Global Star Party 99

Transcript:

kareem i think you have some static oh no okay let me let me adjust my audio
hey kareem did you take that image that's behind you i wish is that better scott
yeah that's better did you use fill flash to get some of the details up in the that
nebular wall [Laughter] honestly it was all good did you use and did you use the new special jwst filter
to add all the galaxies in the background that's what i did all 26 filters
yes man you know the the camera the light path inside of j
west is so complex yeah i mean if if we had those things that you know in our
lab to you know amateur had to turn that thing in to be recollimated
[Laughter] yeah the amateur would just try to re-collimate it himself
you got to re-collimate it by by eye right as close as you can get
porter was amazing at that right david i remember seeing the porter museum yeah
hi kareem it's good to see you good to see you too you're joining us tomorrow with shad uh
the shad kids get to hear david tomorrow evening yeah and what time is that going to be
kareem uh i will log in uh at about uh just before seven and we'll go live just
after seven uh i'll stream you into the classroom okay great that's the plan fingers crossed
everything works that's that always the case you have a plan b
in case but uh my my impression of dovid does not do justice unfortunately
no i know i know david will be there and then david can't make it you can ask conal
cono how are you doing doing all right adrian how about you doing good so what's your impression of
the uh the um show and tell for uh jwst this
morning i gotta say i i loved it um i think they released the other four images this
morning but my favorite is still that deep field i just finished a book by jeff knight
chasing hubble's shadows and it was about some of the different deep field images and
i think that was good timing because comparing hubble to j west with
you know what it can see in terms of gravitational lensing redshifted galaxies and all that that that had to be my favorite image
so i can't wait to see some more of that yeah it's still there um if you haven't seen the stefan's quintet
image actually it doesn't matter all of the images one of the one of the constants about
all the images is that there's a we call it the jwst filter where you
just add it to the image and then boom there's a whole bunch of galaxies in the uh
in the background of the image that lens you know gravitationally lens galaxies too yeah
right so we got some someone called him uh so-called one the salvador dali version
galaxy because it was because of the look it had to that similar to that clock
um so yeah well when you see them you'll you'll definitely uh
i think we'll we were all amazed at uh oh definitely well we could in a short
period of time as david mentioned it's uh you know that's a short period of time
wait till it tries the image um correctly image for weeks who knows what
we're going to see at that point that's true that'll be crazy this is the first day of a revolution it
really is yeah and see they they ought not have me at
the controls because i'll blow everything out we don't see anything what happened ah i
turned the gain up too high ah weeks of work wasted gotta start over
that's why the experts are running the telescope but not me well the issue is once we get i think
it's like a six and a half meter space telescope a world-class observatory that means a lot of clouds i
mean you know how it is a new eyepiece or a book or something oh yeah the earth might be in trouble but
it's going to go on right on tape that's the reason why they put it a million miles out there yeah
that way it gets as far away from the clouds in michigan as they can yes
this is why you buy it and pay for it at one point then you don't wait till you wait to launch it until you have clear weather right
right right you just remind we've had clear weather really good clear weather i've been able
to image for the last uh couple weeks so now that i know what's about to happen
to my skies and everyone's around the world probably be covered in a giant cloud for at least three days
on the dark of the moon so we'll see if that happens i think we need you to knock on a lot of
wood here well i do have some baseball bats i can use those
yeah well for my area it seems the uh the situation is always
that the clearest and calmest weather is during the full moon and for someone who's interested in deep sky that's
i don't know i i suppose it's just the luck up here your only bet is to
as soon as the full moon sets but i believe um
it's because of where we are that only gives you maybe an hour or less of
total darkness and then astronomical twilight begins again yeah
so here it's it's rough but if there's no mosquitoes biting at least
you've got a nice night out that's that's all i can tell you if you
have a nice night out try to make the most of it yeah there's some things you can still see
too um most of the most of the guys just go to
clusters star clusters and trying to split bubbles and triples
the visual astronomers anyways that's true it's a very different camp
yeah some yeah i i try to um
you know tread the uh both sides at oaky text it's become a lot of
um astrophotographers and my friend who's a visual astronomer at least once a night
is telling someone to turn the lights off oh
i can almost count i can count on him telling somebody to turn the lights off every club has a screamer okay that will
tell you shot those lights you know he's striking a match or
something but you know yeah you know people get sensitive about their night vision
oh they i yep i hide my camera equipment far away and behind things
i want no one to have to come at me i'm not even sure what i'm gonna do for my polar alignment
of my little amount because it uses a laser so i will have an alternative
um way to do it when okie text comes in a in a couple of months here
a lot of star parties might have been okie texts i was reading about have an astrophotography section in the visual
section no it doesn't yet it really should not there no it really should
some some do um and then there's some star parties that are visual astronomers only
so it depends on who runs it yeah i forget there's one in virginia that one of my um clubs
mentioned they were going to go to because they're visual astronomers
yeah so they're a couple that are out there astrophotographers out of there
with our bright red and white lights and troubleshooting at night instead of
testing the equipment one of our guys does it the correct way and i see we're about to start he does it the correct
way all of his equipment is in the trailer and all he's got running outside are wires to the
you know the um telescope with his uh camera in the back and so he runs
command central inside where he can cover shades and no one has to see all of his lighting
and um and it works great most of the time it's a tint it's bright lights
it's oh something's not working it's not tracking right and and then
then my foot says turn off those lights and then there's
then there's the big old fight yeah yeah so that that's where
we have together yep
well uh it is about just time to start here
so everybody's watching right now we have some people already logged in thank you for tuning in to the 99th global
star party and we're going to kick it off now
we have uncovered wonders undrepped by our ancestors who first speculated on the nature
of those wandering lights in the night sky [Music]
we've crossed the solar system and sent ships to the stars
[Music] but we continue to search
we can't help it a central element of human future
lies far beyond the earth
[Music]
if we crave some cosmic purpose then let us find ourselves a worthy goal
[Music]
[Music]
uh [Music]
so
so
[Music]
well hello everybody welcome to the 99th global star party we have a great lineup of speakers here as
we always do but uh i think everybody's kind of just on a new high because of the james webb
space telescope images that have come across and uh you know it's just amazing
amazing views that we're getting right now and you know we know that this is just
the tip of the iceberg we know that much deeper much more detailed images are
going to come out many many more discoveries will be made
it uh and it's absolutely amazing that we uh we pulled this thing off uh virtually
without any flaws and uh so uh it's it's just an amazing time to be
alive and if you've been thinking of you're watching the program you're thinking about gosh i
should get into astronomy i'll tell you the time is right now you know this is the golden age of astronomy and
discovery and exploration and you can get started at any level that that you'd like to um
but uh you know we're here to get you started so
um i last week i was with the uh george the
extended family of uh george ellary hale and if you don't know who george elder
hale was he was a just an amazing individual
every time i read about george ellery hale i learned something new uh but in his lifetime uh what he's
probably most famous for is building four of the world's largest telescopes
in sequence he built the 40-inch refractor that's at williams bay wisconsin uh
that's that's the yerkes observatory uh he went to los angeles to pasadena and then up to
mount wilson to build the 60-inch uh reflector the great 60-inch that
discovered that uh that the sun was not in the center of the universe you know that we were
somewhere out off on a spiral arm in the milky way um
and then they built the hundred inch he built the or arranged to get the 100 inch built which is just the story of
how he did this is just uh uh stunning you know he pulled together the world's best craftsman
got together you know rich industrialists and
and got these things built um the 100-inch telescope discovered uh with
the skill of of edwin hubble and humison uh
the the fact that uh the andromeda nebula wasn't a nebula at all but another galaxy
and uh and from there you know overnight literally overnight the universe went
from being just maybe a hundred thousand light years or so to millions of light years in size
um and then uh sadly before george elery hale could see it finished the inch had
already been got started got underway it is still the 200 inch is still a
leading research instrument today and so it's just uh an amazing legacy but on
top of that he was one of the founders of the california institute of technology
he founded the american astronomical society which all the professional astronomers
belonged to today in the united states they also are now inviting amateur
astronomers to be part of that so you may consider joining the double a s
he started a science journal called the astrophysical journal in fact he's the guy that
started astrophysics and so all these accomplishments these many
many i mean huge things any one of them you know building out the city of pasadena is another one
helping uh henry huntington establish the huntington library i mean it's just all these things could have been done
you know would have taken up a lifetime but he just did many many layers of these things and plus he was just an
amazing solar astronomer as well and uh so
it was as we went to caltech to hear
the president of california institute of technology technology talk about george ellery hale
and his legacy and to hear ed krupp from griffith observatory talk
about the accomplishments of george ellery hale was was also amazing
but i thought it was just really um interesting how turned on how switched
on the whole family was uh and and their concern about uh you know establishing um
a path for the the future legacy of those observatories
uh the um a path for the inspiration that george hillary hales had started uh you know
something that will continue to inspire people for the next century and so uh i've never met a family like this
before it was it was really thrilling really amazing uh getting to know them
and be able to make to further my friendship with sam hale who's the grandson of george ellery hale
so he invited me to come down and shoot some video of that uh which was
great and so uh when we went to mount wilson it was kind of a two-part type of deal uh we
went to mount wilson so that the family could see uh firsthand uh you know all the things
that were done at mount wilson from the snow telescope to the 60 inch and the 100 inch
wendy friedman who is uh devoted her life to
refining something called the hubble constant the hubble consonant is this kind of cosmic yardstick this this
method of determining the uh the size and expansion of the universe and
from what i understand and talking to her and it was a real honor to be able to sit down and talk to her for a while
and she joined us for dinner and stuff we could ask her lots of questions uh but her and her team apparently have
already refined the hubble constant down to about one percent and they think that with the james west
space telescope they're going to refine it down to about a tenth of a percent so we're going to learn a lot about the
dimensions and size and expansion of our universe in a way that we never could before with jay west and we have uh
really the world's best team led by wendy friedman who's going to be i think
i think she wouldn't actually say it but i think that they're going to be the first research team on j west so
um i have just a little clip that i'll play here uh it's about four minutes long but uh gives you a little bit of a
flavor the flavor of what that uh that whole event was like uber is delivering to us right now so
we'll see what happens with the james webb space telescope which is what i'm really excited about for the future
so james webb as i mentioned was launched christmas day last christmas and um it's
about to release its first uh science observations every tuesday so i think you'll want to stay tuned for this i
think it's going to be pretty exciting this is a telescope it's six and a half meter telescope hubble's a two and a half meter telescope it has 18 mirrors
these are made of beryllium and coated with gold this telescope um i first
heard about 25 years ago i was on a scientific advisory committee that i had been charged with coming up with
what would succeed the hubble space telescope so this was the idea and a few
astronomers were asked to go to the goddard space flight center we were giving some advice scientific advice and
we first heard about this telescope that would have to unfold its mirrors in space it was going to fly a
million miles away a million miles from the earth unlike hubble can't be serviced it would have a sun shade here
that would have to unfurl in space these things uh each of the five layers
of this sun shield is a width of a human hair has to unfurl in space and then the um
locked into place and the astronomers in the room looked at each other and said this is insane it will never work
and it worked [Music] yeah it's amazing
it was a picture-perfect launch it could not have gone more flawlessly and i think they said there was something like
a hundred um you know single-point failures it was we were literally waiting with baited
breath for each one of these things but it made it a million miles away now so here is um here's the moon this is
hubble's orbit hubble's in a low earth orbit but um here four hundred thousand kilometers
above the earth and this uh the james webb space telescope is now about a million miles to earth and it's a place
called the l2 lagrangian point i'm not going to ask you about that later either
but the first images they took of a star there are 18 of them here that just
happens to magically match the number of mirrors there are so it's actually one star but it was all
over the place they had to spend weeks fine-tuning the positions of the mirror so they knew where each of these stars
should go and eventually they were able to focus it into a single image and that image
for the calibration image turned out to have galaxies in it that had never been seen before so even the test images now
are proven to be just spectacular here is a an image that was taken by the
spitzer telescope at the 24-inch telescope in space and the infrared telescope uh here was again a test image
shown well there's a little red instrument taken in may now why is web so interesting why do you
want to observe in the infrared here's a picture this is the eagle nebula it's a
region in the milky way where it's essentially a stellar nursery new stars that are being born in these pillars
here they're um i think the number is something like six trillion miles high these things
and that's small by astronomical standards um this is a small region in our own
milky way galaxy and you can see these dark patches here we can't see any stars in this nursery
um but when we uh observe a near infrared light suddenly you can start
peering through the dust and you can start seeing where there are stars that just are not visible in the optical
wavelengths and then in the minute when you're going in longer wavelengths you start seeing the dust radiating
radiating itself and and you can find about the dust properties so it has this incredible capacity
also because the universe is expanding with the time as we look farther and
farther back we're seeing earlier in the universe as the universe was when the light left those objects
because light travels at a finite speed that's something that albert einstein taught us
and because of the expansion the wavelength of light is being stretched and it's been shifted to the rim and so we can
observe further back in time so that's uh that's just a little bit of
the you know hour and 25 minutes long uh lecture that she gave um
but uh i felt just you know i just felt so honored to be there uh to see her uh speak live at
mount wilson at such a historic place to such a you know amazing audience the
energy was just incredible and uh and just knowing too that you know jay west
was about to release images and uh so i i was um
you know and further to be able to uh be asked to you know do that video for them
so one day i'll have to upgrade my cameras and not shoot images through my ipad and iphone and webcam
anymore but but uh it's working out so so far so good um
but uh you know today's program uh is about shared horizons and shared
horizons uh like most of the topics that we
choose for a global star party are meant to be either literal or metaphorical you know there
the uh exploration uh that we do in astronomy
takes a lot of uh brain power and there is also um
you know uh a lot of just uh uh elbow grease that goes into uh doing
the work of discovery and um some of that is uh for a lot of this is personal discovery
uh uh that we're making uh for others uh they get so skilled that they they make
you know foundational discoveries that are included in science journals um
but um anyways i think that you're gonna really enjoy the 99th global star party
and we're going to turn it over to david levy now david
is david i wish you could have been there for this particular event in fact i wish
you all why yeah it was uh it was a somewhat private event and um
so um but you know uh i will uh i will make uh those videos uh
known to our audience as we go on because uh i was able to capture a good part of it so
but uh so david uh what did you you know everybody kept asking me what do i think
of the james west space telescope images what did you think
well thank you scotty and welcome to the 99th global star party
i remember 99 star parties ago i got a telephone call from scotty roberts and
he said he was planning to start a global star party and he was wondering if i could come in each one
and begin each one with a quotation from the world of poetry
and i have tried to do that i think i missed one out of the 99 so far
but i am uh really very happy to be there and the theme today shared horizons is
so appropriate because i think in no other time
of the amateur astronomers the professional astronomers the population of the world
and everyone else has had a chance to get as close as they did today with the release of the first
images from the web space telescope i
i've taken a look at them and i certainly looked at the one that president biden
released last night and they're two of the four that are really the really stand out in my mind
one of them is stefan's quintet and of course we all know it's defense
quintet because if we've ever watched if we've ever watched uh it's a wonderful life
the movie begins with a one of hale's telescope's images
of stefan's quintet at the very beginning of that movie
and i have seen his defense content innumerable times with my telescope
and to see it with the web was really stunning stunning today the other image that really stood out in
my mind was the one of the edicarina nebula
i knew bart bock very very well we were good friends
we we started talking short few weeks after i relocated from
canada to arizona to take advantage of the good sky and i
went out i remember visiting him and uh doing an interview of him for an
article i was writing for astronomy magazine there's one person here who might remember that article
anyway thanks david anyway i was there and i
started i brought in an hour tape to tape record what he had to say and i asked him one question
i said when you were in australia you wrote a book called the astronomers universe the first five words of that
book were astronomy is on the move all these years later how would you
assess the accuracy and mood of that statement lord started to talk
and he finished the first half hour of the tape he finished the second half hour of the team
i asked him to to be quiet for a minute while i ran out to my car to get a fresh
tape and then he filled that one as well a two-hour response to the only question
i asked back then and uh we got to know each other very well
we got to be friends i remember one day when uh
a girlfriend of his had decided that she wasn't going to visit him as planned
he was so upset that he telephoned me in tears crying his eye eyes out
asking what does he want what am i going to do and it was really something and i thought it was really special
that he could trust me to reveal one of his deepest emotions
anyway one of the books that i've written was a biography of bart bach it's called
the man who the man who sold the milky way so university of arizona press look and i
believe it's still in print after all these years of all the things that bart loved
and that he knew and that were part of him the thing that was the most important
was his wife priscilla and it was very difficult to separate his accomplishments from ours
the two of them loved the night sky they loved the milky way
and especially they loved the southern milky way and the edicarina nebula one of the most
beautiful things in the sky at the opening of the flandero
planetarium in 1975 november 1975
the imprison arrived pretty early that morning priscilla had been in declining house
for years and they went to the back room the room called the galaxy room
to look at photographs that were there and priscilla stopped when she got to
the at ocarina nebula and bart said maybe we should go in and
let them open the planetarium up now and she said bart
you know i am not well you know i'm going to die soon
she points at the uh at the picture and she said this is where i want to be
when you are alone after i'm gone whenever you want me just look at the etiquette arena nebula because that's
where i will be that is where i want to be priscilla passed away just four days
later and bart loved
to visit one of the things in tucson the desert museum one of the
really wonderful spots in southern arizona and
he decided to build a a bench so that people could
sit there and relax while studying the aviary and the bench was installed in
the aviary and if you look at the concrete structure of the bench you can
see the galaxies inscribed on that concrete
i ended the chapter about the death of priscilla with this paragraph that i would like to
share with you now the bench became a noble retreat for bart
in the coming years he visited it frequently sometimes alone more often with friends
another audience with the roadrunner soon take place out from the bushes she came scampering
through sitting on my shoulder as he watched this roadrunner bart's
thoughts wandered back to a far-off place and town a memory of priscilla
happy and alert as she fed a group of magpies filled his mind
slowly the image faded and he imagined once again the exquisite
swirls of the nebula in korea thank you and back to you
oh thank you so much the very nice it was a very uh
private uh you know view into a great uh astronomer bart bach
you know uh bart bach was uh certainly known for
uh the uh you know his work on the milky way
we were talking about him a little bit earlier if you're you know a newer
into this uh into this lifestyle of astronomy and you're kind of new to it you may not
know who bart bark was but i certainly recommend that you uh you know get on amazon get get one or
two of his books and dig into it because this he and his wife love the milky way they
weren't just scientists they were uh it was such an uh an intimate uh portrayal
uh an investigation into our our home galaxy and uh david was
great friends with that family and um so it's uh if you ever get a chance to
uh visit the jarnac observatory i think david still has a
glass plate of the milky way that's backlit in his observatory that you can see and that is from barkbox so uh
very very cool you know we are so lucky david to have you on global star parties so that you can
reque recount uh your personal experiences with so many of the uh
luminary uh people in the astronomical community so
thank you for being that bridge it's awesome okay so um
we are always blessed to have the astronomical league be with us on global
star party they they have also committed to being on virtually all of the global star parties
and they are you know the astronomical league is one
of the world's largest if not the world's largest federation of astronomy clubs
they have over 300 clubs over 20 000 members and they celebrated their 75th anniversary i
think it was last year was that right john well it's we're still in our 75th year
we haven't hit 76. yeah okay so i don't know how that works unless you hit 75 you're already in your 76th
or you know i don't know so that's that you know i get birthdays
mixed up that way too so anyhow um uh but the astronomical league
has an incredible uh uh canon of observing programs that
people can take uh they have a uh a huge uh uh
you know array of uh astronomical awards that they give out for all kinds of different types of
recognition everything from uh you know the the best uh
website for an astronomy club to um you know awards that support uh young people like
the jack horkheimer award the explore scientific is the very proud
underwriter of two of their three other awards actually now which would include the national young astronomers award the
leslie peltier award for lifetime achievement in astronomy and
also the uh the the uh well wilhelmina fleming award which recognizes uh women in
astrophotography so we're very pleased to be part of all that uh the league comes on each week with us
for global star party to uh to read off uh questions that they that they uh come up
with and uh they do the door prizes for global star parties so i'm going to
turn it over to john goss um john thank you so much for being able you're welcome
you're welcome um i've been telling everybody that today
is all about the james webb space telescope so i i got got my little version here so
that's cool yeah i i was trying to get it to put on my shoulder but it kept falling off no velcro yeah
okay well uh you know you're talking about how old the league is 75 years uh
since i've been advancing in years my grandkids have asked me how old i am so i instead of telling them you know it's
always a big secret i uh i convert the number into a base six notation
so the league is now 2-0 to 2-0-3
uh years old in base six keeps them guessing makes you sound makes you sound smart too okay well try
to fool everybody at least but anyway uh thank you for having me on and i'd like to jump into something right now
and uh see what we got here
hopefully i got it here
okay i got a blank spot right here but let's go the first slide sure
now this is personal uh stephan's quintet as we're just talking
about a few minutes ago the image on the uh this side i guess that's the left side
is something that i was acquainted with uh when i was a kid you know in the 1960s this is from uh
burnham's celestial handbook which i'm sure you've all seen but this is this is from luke observatory in the 1960s so
this is my image in my mind of what stephan's quintet looks like of course the one on the
right uh blows everything out of the water um and the one on the right is actually
kind of compressed up to to match the old image you could certainly zoom in on it and get a lot more detail than you'd
ever expect to see so to me this is a specific advancement in my lifetime
on on what astronomy has has come into and that's great you know i that that
that that that's that's really super um so anyway i'll i'll leave you with that let's get on on to our questions
because i don't want to take up too much time here first thing we'd like to do is remind everybody about proper solar observing
this is especially coming in into importance because we're now entering into solar max
which there's a lot going on in the sun and so more people are going to be looking at measures but make sure you
have the proper solar filter fitted on the front end of the telescope make sure that your um finder scope is
covered up make sure that your red dot or your reflex finder is
unattached uh so the sun won't damage it but if you have the the right filter in there you can see some great stuff let's
go on to the first question well from last week
answers from last week scientists have begun to announce the first results from the analysis of material brought
uh or back uh from asteroid uh ryuku what spacecraft brought this material
back to earth well the correct answer is is c hayabusu two
and that's pretty cool because you don't get much material from outer space pristine material like that
this is kind of tying in with the uh james webb since we're talking about ada karina well this is a another nebula uh
messier 16 contains a nebula contained nicknamed the pillars of creation that was from the the
the hubble era what's another name for the for this uh nebula it's the eagle nebula
um you see an eagle in there i guess johannes kepler was a german astronomer
mathematician astrologer which we won't talk about and natural philosopher he is
best known for his laws of planetary motion he had three three laws tying it
all together so if you had your answers to that and uh we had some
a number of people who had had correct answers uh cameron gillis which i think he's on on the program today someplace
uh john williams larry birds uh colonel richards i call and andrew corco
thank you for submitting your answers the gsp winners for june kerry todd cameron gillis and larry
burge so let's move on to tonight's tonight's questions
okay we're all about the james student space telescope something which i i think that
people don't really realize is that it's really up there in space someplace you know you can point it out or at least
point its direction if you know where to look so in what constellation into night sky is the james webb space telescope
located uh if if you know a little bit about the telescope's orbit and all that this
should be kind of kind of obvious that's question number one number two
what is the true field of view of the james woods space telescope's primary instrument the near infrared
spectrograph is it a three arc missed by three arc minutes b
three degrees by three degrees or c three radians by three radians
it does have a field of view question number three
um i have i happen to have a 17 inch dobsonian
and this primary mirror is about 17 kilograms
something like that so i was thinking about well what about this james webb that it has 18 4.3 foot mirrors i know
mine mine is a little 17 inch hexagonal shaped mirrors how much does each beryllium mirror weigh on earth
a about 20 grams actually has to go up in space so they want to keep it light
b about 20 pounds or c about 20 kilograms so it's one one of those three answers
now if you know those answers uh be sure to send them to secretary at astrology.org
and um you do that soon and uh it'll be entered into our drawing
for july now i'd just like to put a plug in for our con 2022 july 28 to the 30th
embassy suites hotel in albuquerque uh this is a three-day event with speakers and tours and workshops and
and get-togethers and gatherings afterwards and star parties and such so it's a lot of fun but uh you might
consider going uh although registration is closed but maybe if you show up at the door they'll still let you in
anyway i think a number of us are going so i'm looking forward to seeing all of you
there um that's what i got thank you scott great
thank you thank you very much that's awesome okay um
so where are we at now we are uh at the point where uh
we will introduce david eicher david is uh uh
uh the editor-in-chief of astronomy magazine uh he is but he's more than
that i mean he's this is a guy who has really devoted his whole life to writing
about uh uh the science of astronomy uh starting i think when he was a teenager um
and uh david's no longer a teenager but he still has this youthful appearance and i
think that has to do with uh his good sense of humor uh if you get to meet and know david you'll
know that he is uh quite the crack up and um he is also someone that uh has been a
driving force in both amateur and professional astronomy uh you know he is uh
you know they they put out astronomy magazine puts out not only a print issue but they have their website they do a
digital issue they do special events and they're coming up on sponsoring one
of the biggest events in the world for astronomy which is called starmus and so
but david sees the universe from all all angles all corners and uh we've been
following him with his special collection of of minerals and crystals uh of course
these are all things made from uh you know the uh the cauldrons of
stars and and so uh and the the things that he shows us are just
beautiful and uh so we're lucky to have him on to talk
about all these different aspects of the universe and i think today he's
going to be covering is it calcium calcium potassium and a bunch of other
stuff and a bunch of other stuff okay well uh you know thank you again david for
coming on to global star party and uh i know that you've had a really busy week
uh so far and it's just really started so thanks for coming on thanks scott so
much for having me i'll share my screen um and see if we can start the slideshow
and it is a very very special and now let's see if we can view the slideshow
it's a very special day as we all know because this is the first day of a
revolution and uh this should last we hope about 30 years but uh
we had just a small taste of what's to come of course this morning but we saw a lot of new places that we'd
never seen before at very large distances and we were talking earlier about astro
imaging and how we're going to have to get used to now all these new images that we're going to see
with all these little pesky proto galaxies in the way everywhere um but
but they're places uh where uh these minerals are coming from and so
this is really planetary science and how the universe creates planets
uh from the stuff that makes up stars and makes up people and other living
things as well and i think we were obviously wow david you talked so very
eloquently about uh bart and the carina nebula
and the images were all beautiful but i think there was a kind of a sleeper in there as well and adrian and i were talking about this a little
earlier uh the spectrum of the exoplanet which uh you know was thrown
out as a kind of an ordinary uh exoplanet of which we know of many many similar planets um which has water
vapor in its spectrum which is very interesting so anyway we'll get to
uh in a golden age of astronomy a flood of amazing data that we'll have to race
to keep up with as we get more results from webb so we're in a very exciting
time but to step back and talk a little bit about planetary science we'll start as
we always do uh with thomas jefferson saying i believe in a divinely ordered universe
well even before jefferson's time he both these guys are even older than i am scott now i'll have you know you know
i'm no longer young but isaac newton was even older than jefferson and he said
truth is ever to be found in the simplicity and not in the multiplicity and confusion
of things so of course as we know back to the time of galileo and and before
even we've taken what were relatively primitive uh modes of thought
um uh all of which had analogs that transformed into the sciences for
astronomy it was astrology and for chemistry it was alchemy
and coming together in between the two of them we never had alchemists who met
their greatest goal of converting lead into gold but we found out a lot about these
substances and how interesting they are and how they show us what our planet is all about
so the universe is ordered not by supernaturalism but by the principles of physics of course minerals demonstrate
that because their atoms are assembled in precise ways by electrochemical attractions inherent properties of the
atoms that make them up and guide them into assembling into what mineralogists call a crystal
lattice that builds these substances as fluids typically fluid warm fluids hot
fluids come together and crystallize these substances
so we're starting to sort of run out of uh great organization here because we've done so
many of these and and we're getting into some sort of groups of things that we're on
photograph together on particular shelves so we have some calcium here we have some potassium
potassium and we have a few other things and i thought i would mention an interesting sodium mineral
which i'll show in a little while here is sodalite which is a really beautiful blue typically blue mineral sodium
aluminum silicate chloride but it comes in all sorts of colors it's
not inventively enough a member of the sodalite group all sorts of related
minerals and it's usually an accessory mineral that that forms in alkaline igneous rocks so this
is we're getting into a little bit of grab bag type stuff here because these were all organized in display shelves
and we're running out of big groups of things that were all together so anyway here's the crystallography of sodalite it's
isometric which is a fancy word for cubic uh and brings together uh sodium
silicon aluminum oxygen and chlorine atoms to form these crystals
but we'll jump around a little bit here and and talk about some of these minerals that are kind of loosely
related by these chemical elements this is an alcene uh which is sodium aluminum
silicate hydrate this is kind of interesting not so much that it's a sexy mineral but you can see the these
dodecahedrons here i hope in the image that are making up the crystals but this comes from a very famous island that all
astronomers should know we know the great places to observe on earth
which david isn't about the best place you can be in the continental united states in
southern arizona there but we also have mauna kea in hawaii that's very good and we have
of course chile and the atacama desert probably the best place on earth overall
but we also have the canary islands and it's on la palma uh where this specimen
is from where the great observatories are on the canaries where undoubtedly
scott you mentioned starmus undoubtedly the starness festival at some point is going to be headed back to
uh the canary islands so we will get to visit this locality
great and we'll jump around to a bunch of related minerals here this is another
calcium mineral serandite sodium manganese calcium silicate
hydroxide the pinkish color here coming from manganese atoms this is from a famous mineral locality
uh in monsanto quebec canada which i think is relatively close uh for
a couple of you as well or or your past heritage uh to a couple of you
as well um so there are great specimens of really unusual and complex minerals that
come from this area this is eudilite which is sodium calcium
cerium iron manganese zirconium silicate hydroxide chloride now can you cover
your screen and repeat that back to me three times here we're getting into a real chemical soup a complex massive
stuff that got together to create this uh reddish crystal that's that's near
the top of this specimen which also has a gerine which is the black stuff uh
that's a silicate and some other minerals as well but the udiolite is that sort of a beet red crystal and you
can see it's got just about everything under the sun in it and it comes from another famous
region the cola peninsula in russia
now there was once a great crystallographer in fact he was the father of crystallography renee hui
h-a-u-y he was a french chemist natural philosopher and invented the first
complex models explaining and understanding how the different crystallographic forms come
together rene hui and queen
which is named after him is the mineral that bears his name this is sodium calcium aluminum
silicate chloride another real grab bag of elements here and it forms this kind
of gemmy bluish bright blue peacock blue uh crystals of stuff and you can see
this is in volcanic basalt so this comes from a volcanic very high temperature
region of forming this mineral from germany
now this is angled and you may have seen this stuff it's fairly common but it's very pretty so this is kind of a
star feature of many mineral shows where you can pick up a piece of this
this is a pretty common mineral feldspar type mineral called a northite
but it's a particular kind called labradorite and it's very very fairly common but but also very
popular because it's beautiful and what this does it has several layers
of hydrated stuff in it so that you can change the angle of this glassy surface
this has been polished the top surface of this and light will diffract uh and
reflect through it and so it gives you this what what scientists call a shiller effect of a shiny
multi-colored surface here so it's a not terribly uh
super rare but but pretty thing and so it's often used for jewelry as well and this is sort of the
their their canadian area of course labrador um the type locality but also
more recently many specimens of this that are found in this area of madagascar so it's pretty stuff that
gets made into a lot of jewelry now we're getting into some more weird stuff just to show you kind of the
range of how nature makes really different things out of some of
the very similar chemicals but combined in different ways in different
temperatures and under different pressures this is a lavenderline which is sodium calcium
copper chloride arsenic hydrate this is a chilean piece and the blue color here comes from the
copper and and also the green related greenish mineral called glamorite which
is also colored by copper in a different way which is the green stuff here so you
can see subtle variations of how nature likes to make stuff
produces really different results out of much of the same components just as the way we see
another 10 000 galaxies in a web image that are made largely of the same stuff
but they look all different you know so there are analogs here at small scales and large scales out in the universe
here's another example of levindulin and again you can see it's really sort of bright peacock blue here in a kind of a
not so wonderful looking gang uh rock specimen country rock specimen
and this is a greek specimen here
samplite looks pretty similar to what we just saw the last couple of frames but this is sodium calcium copper phosphate
chloride hydrate with a water stuck on there as well so
all kinds of complicated chemical soup formulae going on here to create this
stuff this is another chilean specimen and these chilean atacama specimens of
course come from a really what's good about the atacama for observing two things
it's a pop quiz high elevation and of course it's exceedingly dry you know a wet day in
the atacama is probably about four percent humidity so these minerals are
dry minerals that are sensitive to humidity as well
here's another example back to germany from a different but similar volcano in germany of hueen again this is just kind
of these are cycled in here uh in the order in which the shots were taken here
um but again it's sort of pretty stuff that that even forms in almost
grain size pieces here in this volcanic basalt
here's another quebec specimen here from also from mont saint-hillaire
this is carltonite which is a somewhat rare mineral and again we're getting down to you know
chemical formulae as long as our arm here potassium sodium calcium carbonate
silicate fluoride hydroxide hydrate it's got everything but the kitchen sink practically in it here but gets a very
pretty blue color here from this famous canadian locality
this is a polished piece of very pretty stuff and again this is fairly common
and really uh popular at jewelry and rock shows and
things like that it's called cherowhite and that's because it comes from uh the best stuff of this type
comes from an area along the chera river in in siberia
and this is sort of a mixture of things but the purpley stuff is cheroite sodium
calcium barium strontium silicate hydroxide fluoride hydrate
again it's got you know practically everything you can think of in it um and a couple of fairly rare elements barium
and strontium uh and is a polished piece and this stuff again is fairly uh um
popular uh with jewelry and mineral rock collectors who are
collecting these polished uh stone pieces now here's something of kind of special
pride for me this is about one of the ugliest minerals in my specimen collection uh but it's it's a it's a
favorite uh of mine because it's called rakavanite and this is named for the professor who
researched it who of all places is a tiny little miami university in oxford
ohio where i grew up um and it was a friend of my father's uh
john who was a professor there at miami as well john rakavan analyzed this piece and and
it's named for him and and it's pretty rare stuff doesn't look like much it's sodium vanadate hydrate
and it comes from primarily one mine a few others but but
the goods believe it or not this is a good specimen even though it's kind of not the prettiest stuff in the world and
it comes from just one mine of this caliber in colorado is it is it kind of delicate this this
is very delicate and you can see there's a crack through this piece that goes
from the uh sort of mid-left down to the middle right and it's sort of crumbly it's not it it
okay many many many radioactive minerals by the way which we've talked about eons
ago but they have this kind of a bright yellow look so this kind of on first
blush looks radioactive frankly to mineralogists it's not radioactive but it is fragile and
crumbly and delicate yes absolutely right
here is another one of these minerals that here's a polished edge of this and
this is again very popular with mineral collectors and jewelers jade this is
jadeite sodium iron aluminum silicate and this comes from a very famous region
where this greenish jade is found in myanmar or as jay peterman on seinfeld would say
that must be burma to you but now it's myanmar and that's where a lot of good quality jade
comes from here's another one that's very very delicate and you can see it almost looks like a flower the large
crystal here called nature light and it's quite fragile here and and is made
up of what mineralogists call acicular crystals that means needle like
and it's fragile too on this kind of ugly country rock but this is a new jersey specimen this is sodium aluminum
silicate hydrate and again contains a lot of h2o that's locked up in it very fragile and looks
uh sort of like a ball like flower
okay here we're going back to some purpley cherry and some of this ordinary
black green green black looking agering but the unusual stuff here is this uh
rare stuff here is this kind of tan colored tinka site this is again from
this eastern siberian region of russia where the cherowhite comes from
uh of course but this is potassium sodium calcium manganese titanium
silicate hydroxide so again as we're running out of minerals here we're getting into some
weird more exotic combinations of stuff here and this i threw in for my pop john this
was in an old timepiece in his collection this is sodalite which i mentioned which is a fairly common
mineral of this type it's sodium aluminum silicate chloride uh and it's from a very well known uh
locality in ontario the bancroft district of ontario which is very rich
in mineralogy and this is an old timer this i think was uh found in the 20s or 30s
but it shows you kind of a good look at what soda light looks like
here's one for the astronomers any astronomers in the crowd after are you talk tired of talking about
starting at eight o'clock this morning um in the central time zone this
is astrophyllite named wild because boy this radial
mineral crystal looks kind of like a star there doesn't it a little bit potassium iron titanium silicate
hydroxide titanium rich crystal and this again is from this
russian locality the cola peninsula with a lot of these exotics there
and this is another one that the jewelers really like here and this is not really one mineral but lapis lazuli
which was one of the great early stones if you will in the uh
in the region of afghanistan and pakistan and other areas of the
early world this was a bright blue and exciting rock that was mined
three and four thousand years ago in afghanistan and other regions nearby and
uh it can lap it's largely sodium calcium aluminum silicate sulfate but it
consists of other stuff here and you can see these little golden specks in here which exist along with it which
is just ordinary garden variety pyrite so that there are some other minerals in here with it but
the blue stuff is lapis lazuli which is one of the earliest minerals to be mined
in human history and also was ground lapis in the egyptian times
and used for some of the earliest eye makeup um for cleopatra and friends
so this was one of the earliest minerals to be ground and used for non-economic purposes if you will to
make uh eyes look better and by the way in egyptian times it's not just the
ladies the guys put on eye makeup too so you know we're kind of falling behind the
times here guys so anyway i'm starting scott i have a confession to make i'm starting to run
out of shells of minerals at this point and a few more times we'll probably can
wrap this up and go back to well you know there's going to be some astronomy to talk about but first i'll talk again
one more time or so about starmus and uh we're excited about this because we have
actually a full slate of speakers now and charlie duke and nicole stott and other astronauts and kip thorne and
george smoot and garrick israelian and jill tarter and other astronomers are going to speak there and we hope that
queen are on tour right now but we hope that we'll get brian may our pal and rick wakeman and peter gabriel to
play some rock and roll there and scott you're going to help us put on an incredible star party yeah
and you're also going to be speaking with uh our pal michael bach and myself
at an astro imaging school and we're really happy to have you involved this time this will be in
september in yerevan armenia yeah you can't i mean this is so huge for me uh
to be part of this so i'm i'm really excited about it i've uh followed uh starmis since it
started and um uh you know was thrilled to be asked
to go so that it's fantastic now i'll tell you uh
the people that organized starmus have made it inexpensive to go um i think
ticket price is what two hundred dollars something like that i think so pretty much for the whole week and yeah i mean
that's i've never been to armenia and and i don't think you have either scott but we're discovering that
you know uh room and board you know hotels and food are cheap too so it's really the
getting over there and flights are not so expensive either i was just i was looking on uh expedia and found flights
starting from about 680 bucks round trip you know from the united states so
a lot of europeans uh will go there you know so so there are lots of flights
regularly which i think explains that i believe so
it's much less exotic if you will inexpensive than you might guess going
to a place uh such as this so we're really looking forward to it it's a very dark
sky we're going to have a star party in front of a 2 000 year old armenian temple yeah
this is gonna be really unbelievable and we're gonna we won't give away too much but we're gonna have a band there and
all kinds of things in a a couple thousand people so this is gonna be a great adventure and we're really proud
and happy to have you along this time scott with us thank you thank you i'll be sure to wear my lapis lazuli uh eye
makeup [Laughter] gotta look good you know don't look good
you do that i like my blue eyes so i promise you we're gonna get you and keep you up on stage if you're wearing lapis
lazuli blue eye makeup okay uh
anyhow david thank you very much thank you you guys don't know what goes on behind the scenes before we go live
okay between me and and david and and uh and virtually everybody else that uh that
shows up here so uh the new the new guys um
that come on to global star party really don't know what they're getting themselves into but uh we try to keep it
fun so um but uh i i david i really want to thank
you for going through all those crystals and minerals with us i've learned so much
about uh stuff that's right here on this planet so um and i and it makes me realize that
there's so much more to learn well thank you and and you know we just saw this morning
several hundred galaxies at least we had never seen before you know and
you know of course through spectroscopy that chemistry throughout the universe is uniform so undoubtedly the elements
that we know of are combining on worlds that are orbiting uh stars that
we see in those images and galaxies that we see for the first time and holding those in our hands so we can imagine
what some of those worlds that are so far away must be like as well right right and so it's
amazing to look so far back into time like this you know so uh we're getting to experience something
that no astronomers no humans have ever been able to do you know so
and it's uh it's it's just uh just another shared horizon so it's fantastic
and speaking from north of the border and i'm sure david will agree with me on this we were happy to see the amount of
canadian content in david's minerals today there are some good canadian localities
and the minerals that really come from canada from various uh
sites don't really exist in a lot of areas elsewhere so so canada is really
uh the top of the pops if you will for certain kinds of minerals
it's one thing that is really incredible they're they're really unbelievable specimens of garnets yeah that come from
uh the asbestos region in the jeffrey mine the asbestos region in canada so so
canada is king or or queen however you want to term it uh in a variety of ways
for mineral collectors it's shared horizons so just like scott was saying yeah
well uh that's a nice segue to uh professor
kareem jafar jafar uh from john abbott college kareem uh was really excited to
put together a presentation about the james west space telescope images and uh
so i i think that uh i i don't know how i arrived on having a global star party how i did
this you know two years ago so it would land on this day uh when they're announcing all this stuff but uh we're
lucky that that it happened this way so well you know like you talked about the behind the scenes we've been chatting
away and we've come up with a new holiday that'll fall every july 12th you're going to dress up in gold foil
lapis lazuli eye makeup and give us all presence of infrared imagery that's right this is this is now work
i will you know so i think it'll be fun you gotta have fun
i mean come on you know so plenty of stuff to worry about but
wow what a time to be alive really i mean you just gotta
really be thankful that uh you're live at this time and able to witness this uh
firsthand so i think we're gonna have to take your uh your airstream and redecorate it as a
jwst on wheels hey you you've got her you've got her
mind right now that's right that's right so uh with today's amazing um
press well last night's first um deep field image that was released by president biden and then this morning's
images when scott brought up the idea of shared horizons they said you know let's talk about extending these shared
horizons and talk about the james webb space telescope and i have here the crocheted james webb mirror that my mom
made me and so i kept my background off for a moment but i think i'm going to spend the rest of today coming to you
from the karina nebula because i loved david's story and the the
it really was touching and so i think this is this is where i should come to you from for the rest of today's talk
and i'm going to share with you a little bit on these incredible images that we received
today from the james webb space telescope now a lot of us had a chance to be part
or to watch the nasa feed and uh it was really unfortunate uh that the csa portion did cut out but i
will go to some of the content that would have been covered by dr natalie willette and maybe at some point one of
our future global star parties will get her on to talk a little bit more about nearest and some of the work that the institute for research on exoplanets is
doing uh today during the day the space oddities we actually had a special
tuesday show to talk about all the different images that came out and i want to thank some of our gsp audience
that joined us yesterday during our regular show yesterday when we live streamed
president biden's release of the first image and today i mean we have a lot of really dedicated astronomy enthusiasts
out there and honestly it really is shared horizons across the world maxie came on and
immediately you know said congratulations on a historic day internationally and if you look at the google doodle it is the james webb deep
field today with the james webb space telescope uh little cartoon there and
you'll see it on the google doodle and it takes you straight to those first images
now before i jump into all of that though i always start off with a little bit of a check-in and if everybody remembers when we had our last gsp i was
talking to you a little bit about our rasc general assembly which happened the last
weekend of june and dr natalie willette who i mentioned earlier was our helen sawyer hog lecturer
it was a fantastic talk dr sarah seeger from mit was announced as our honorary president for the national rasc we had
alan dyer give us a talk on imaging dr robert cardinale talked about first nations and
the connection to nature and to the night sky but i was really touched during the
general assembly because one of my former students emily laflesch won the president's award from the rasc
that's the award on highlighting something beyond the normal in terms of a contribution and she was the inaugural
chair of the next gen committee we also had our own jenna hines who was
our past outreach officer who received the killak award which is the outreach award and jenna was the co-host of the
great conjunction uh global star party back in december of 2020 if anybody
remembers that far back in time the other thing that happened during the general assembly is we had an astrophoto
competition and one of the winners and a runner-up in another category adrian bradley our very own is going to be
giving a talk for the rasc montreal center this saturday and so you're all welcome to join us it's during our
clubhouse so it's our regular clubhouse zoom you can come straight in bit dot lee slash rask montreal saturday 8 pm
and it should say eastern daylight time my apologies it's not central time not pacific it's eastern daylight and he's
going to talk to us a little bit about his sleepless summer nights and take us on a journey to his pictures his
favorite pictures and a little bit about his processing approach now i can't get
those those amazing wide field shots that he gets one of these days i have to go down to michigan and do them with him
but i have access just like the rest of you to the james webb images like the one i have here behind me so i want to
talk to you today about these first images that came out and it's very hard in 15 20 minutes to
do real justice to the amount of science and the amount of information that is in
each of these images but i'm going to try my best to do a little bit of each image and talk to
you a bit about some of the highlights that you'll be hearing more and more about over the coming weeks and i'll try not to go too much more than what three
hours scott is that good three and a half okay so with the james bond
it's just time any of it right so exactly we often hear about the james webb as the successor to hubble but it's
a very different instrument we've heard about that already it's not just different because of the size of the
mirror which i'll mention in a few moments but it's also because the amount of different instrumentation built in is
specifically to look at the infrared region of our of our electromagnetic
spectrum there's very little overlap to the visual and none at all to the ultraviolet area that hubble did touch
on at the extreme low wavelengths of its ability to look at the night sky
the other difference is the fact that it's a much colder telescope in the operating side because of that amazing
sun shield and so when we put it in its position in orbit it's to particularly keep it out
of the shadow of the earth or the moon at all times so that you have a constant
temperature differential across that sun shield and that means that the majority of the instruments are naturally cooled
by that sun shield and the cold expanse of space and then you have a few other
instruments like the mid infrared which require additional cooling and so those instruments run off of a little bit of
an additional circuit cooling them down to operational temperatures that allow us to even see some of the dust-like
structures in some of the targets that we look at now we said this is shared horizon so i wanted to show you a picture of some of
the individuals who took part in building the james webb space telescope and it really is a conglomeration of
many different countries the three leading groups that put it together are nasa the
european space agency and the canadian space agency we'll be seeing a little bit of the results of the work from all
three today so one of the questions is what can the james webb see and how does it differentiate from what hubble can see
so we have several different instruments that we're going to talk about at different moments but one of the big things to keep in mind is that when we
talk about near infrared there is a slight overlap into visuals so near infrared runs from just about 0.6 to 5
microns and 0.6 to 0.7 microns is still within the red of our visual range
but in total for near cam the near infrared camera you have 29 filters
available to you so the images that we're going to see are not images from just one band of infrared they're images
put together over multiple different bands and the precision of those bands depends on the target we're looking at
and the resolution level that we want to see and then you have the mid the mid infrared and the mid infrared mirror cam
takes you all the way out almost to 30 micrometers now 30 micrometers takes us
almost 14 times longer in wavelength than the longest
that hubble could see and because our resolution changes as per the wavelength that we look at it
actually gives us a lot of versatility to look at different types of targets with different degrees of resolution
the other thing that's really different about the james webb is the size of the primary mirror because we've built it
from hexagonal smaller subsets the total mirror gives us seven times
the light gathering of the hubble primary mirror so you have more photons coming into your light bucket you have a
different visual range that you're looking at you're no longer looking in the direct visual you're now looking
into the infrared the slightly longer wavelengths and because you have a colder telescope
you're not affected by the heat of the actual operational machinery as hubble was because hubble itself would get hot
as it collected those photons the james webb space telescope stays cold on that side
so the first image that was released last night and i gotta tell you i keep coming back to this image because
there's just so much to see here this is part of the
smacs0723 region of space that is a massive galactic cluster now smacs for
those of you like i didn't know what it was when i first saw it it's the southern
southern maximum cluster survey or massive cluster survey
sorry southern massive cluster survey and it's a survey of clusters of galaxies that are so massive that they
do bend space time around them which is why you see all of these gravitational lensing effects around that central
galactic section of of core of galaxies so many of them that are visible to us there now this area is
about uh 4.6 billion light years away from us the the target smacs
0723 when we look around it what we're seeing lens are much more distant galaxies
that's light is being bent towards us and how do we know we know by looking at their spectrum and in fact if you zoom
into one region here around the top right of this image you can see galaxies
of different intensities because some of them are very faint distant galaxies and some of
them are brighter galaxies a little bit closer to us around five six million light years away a billion light years
away apologies different types of galaxies and then you see a lot of these lensed effects and
these lens defects are often the same galaxy showing up at different points around a circle from this cluster that's
bending the light and that's that einstein cross effect that we've heard about in previous gsps
what i find really amazing about this is the closer in you zoom to any part of this deep field you really do see more
and more galaxies of different types and you see more and more evolution of less evolved galaxies that you can start
to see and you can start to pick out like that one interesting one uh just here at the top uh left of this zoomed
in image where there seems to be this elongated side of it where we don't know if we're seeing it side on or whether
we're seeing a stretched uh gravitational lensing effect and that's one of the ones that we do really want
to study but when we look at any of these spectra from the galaxies we look at the atomic
spectral lines sorry we have some renovation being done at
home so there's a lot of dust in my office unfortunately but the placement of these lines is
something that we know from molecular and atomic chemistry so when we see where they're actually placed we can
determine the shift of these lines which tells us using the hubble constant how
far out into the universe they are and this particular galaxy that we see here works out to about 13.1 billion
years away so within this entire picture you can take different galaxies and you can
figure out based on where the placement is of for example their hydrogen bomber lines how far away they really are and
how much you're seeing them shifted and lensed into our field of view
we've managed to get to galaxies that i believe go as deep as 13.4 billion years
which is just a little bit further than the hubble deep field had gotten now that hubble deep field is the one
that we're hearing a lot about this comparison between the hubble ultra deep and extreme deep field
compared to this james webb image now there's a lot of differences here first off the hubble pictures were taken
over days and days and days of time this james webb picture was a total integration time of 12.5 hours
so that's less that's just a half a day in total across multiple filters
but the other big thing here is because hubble has to stare at the same region of space for days upon days upon days
you have to pick a region of space where you have no bright stars that are visible from within our galaxy
no bright close by galaxies because if you have either of those the photons
from those closer targets or brighter targets will wash out anything else that you might see
whereas the james webb space telescope image had very bright stars from within our galaxy directly in it because we
didn't image for a very long time it didn't wash out the rest of the image so when we look at the james webb
compared to the hubble you can see just in this one region of overlap how much more is visible
of smacs0723 when we look at it by the james webb space telescope and
the area that i love here is in the bottom left corner because in the bottom left corner you can see a couple of things happen you
can see that the stars diffraction spikes that we get because of the 18 segments and all the trusses of the
james webb space telescope yes those diffraction spikes are bright and they're longer
but the area closer to the star is much more sharp so there's less of a diffuse
area around it so you can actually pick out the occasional galaxy very close to the star in between those diffraction
spikes and then you can see how many more galaxies pop into view when you zoom in
if we look at the core of this area and we compare hubble versus james webb space telescope at the core
again you can see so many more galaxies pop up look at the top left area you can see a string of galaxies pop in that
were not visible to hubble at all so when david eicher mentioned that we saw you know 500 or so galaxies we didn't
know existed i think that's a very underestimated number to what we
actually will see when we zoom into all of these different points and we do you know some sort of a plate solving to
compare to the ones that we already know are there sticking with galaxies stefan's quintet
the one that starts us off on it's a wonderful life the one david mentioned this is the james webb image that was
released this morning it is a beautiful image of this group of and it's actually the four galaxies on the right are an
interacting cluster of galaxies that is around i believe 290 million light years
away and the one on the left here is actually only 40 million light years
away so it's a much closer foreground galaxy but the brightness is comparable
to those when it's taken together so it actually looks like they're a quintet but they were actually a quartet plus
one a little bit closer but there's some really amazing things to see here for one you can clearly see this this
colliding set of galaxies here right in the center you can see an extreme tidal
tail actually a few of them off of the top galaxy and if you zoom into any part of this
you see so many faint galaxies that we did not know were there now this total image
in width it's about a fifth of the size of a full moon so that's around six arc minutes in size
but it's this whole picture was developed from a thousand separate files
that were combined together wow now if we compare it here to the hubble composite image versus this one you can
see how many more of those distant galaxies are visible you can also see that the details that we can see with the james webb space
telescope are different than the details we see with hubble added in to chandra
because this has some x-ray information in it as well the composite picture that's there that we compare to and
thanks to harold locke from our audience for telling me that there were these awesome gifts showing us the before what
we knew of the stefan's quintet and a few others versus what james webb has given us
now our own russell fralick here in the montreal center dug out his view of stefan's quintet
and i wanted to share this with you because this is a target you can actually go look at in your backyard
and you can actually see all of those galaxies right there that you see within
the james webb space telescope release here so i've decided that russell is now going to be called james webb light from
from here on in that's his nickname now i wanted to compare for you the near
infrared with the mid infrared when it comes to looking at something like galaxies so this is the image that was released
this morning this is the mid infrared version of that image notice that not only do you see
different features and different details because the dust is highlighted more than the gas when you look at the mid
infrared you see a lot of star forming regions in a different way than what you see in the
colliding picture here on the left but what i find incredibly interesting
is the center of this top galaxy is now totally blown out
so that is an active galactic nuclear core it is a massive supermassive black hole
a mass of about 24 million solar masses and it gives out energy of about 40
billion suns worth of flux so what's really interesting about what
james webb can do is that if you take near cam and you take miri they have what's called an integrated
field unit and the integrated field unit can take spectroscopic slices
of this specific target and you can see how much is atomic hydrogen how much is
iron how much is atomic hydrogen in a different energy level and how much is molecular hydrogen and you can pull out
the actual jets coming out from inside of this active galactic nuclear core
290 million light years away from us that's just incredible that's
tantalizing and astronomers getting on this instrument must just be salivating to get their data the way nasa was
referring to it was slice and dice it's the way in which you get an mri when you go in and they take slices along the
vertical of your spinal column and they piece it together to show you exactly what's inside the 3d aspect of this is
just absolutely mesmerizing amazing and then you have the cosmic cliffs the
one i have behind me from the karina nebula and this picture just takes your breath away
but then you start to see what this picture is showing you because through the dust and gas
of the karina nebula even these areas these pillars that are some of them are up to seven light years height
when you look at these these are larger larger sets of of dust and clumps of
matter that have not yet been blown back by these groups of stars that are really
hot young stars that are blowing back and ionizing the radiation and that's what you see with this blue glow
around this this wave that appears to be there and then inside this wave you see
little pockets of other new stars being born and when we look at this
i wondered where the heck this was because this was the picture of the karina nebula that i had seen before by
amateur astronomers this is what i remember the korean nebula to be so i was trying to figure out where the
cosmic cliffs are and rachel wood from our space oddities figured out that it
was that top right the northwest corner if you look at that bottom part of this
this is what we were seeing in that other picture but this is the hubble version of this
so when we compare the hubble to the near cam to the nearest version
of this exact same region you see the amount of detail you can compare to when
you look visual when you look near infrared and when you look at mid infrared all of a sudden not
only can you see more of the dust you can actually see protoplanetary disks
around some of these stars because it's highlighting the dust it's
incredible and so harold again shared with me a link where you can see the hubble image of this
area the cosmic cliffs overlaid with the james webb space telescope image into
the exact right proportions and so i felt that this was kind of a really good takeaway of just where like
our increase in understanding of what's happening in this region right here
now that we can see through the dust with the near infrared and this cloud this area this this star birth area is
about 7 600 light years away from us coming a little bit closer we come to the southern ring nebula ngc 3132 this
is 2500 light years away and here we see on the left the near cam and on the right miri and here while you
see why miri is so important because when we look at the mid infrared what we
see here clearly is that this planetary nebula is around two stars
those two stars are here as well in nirkham but the one star that's brighter is not the one that gave rise to this
planetary nebula it's actually this fainter one and it's curve it's covered in dust which is why it doesn't show up
as much in the near infrared or in hubble's visible and hubble's visible
it's so faint but in miri you can see just how bright
this star actually is that's given rise to this multi-layered planetary nebula
what else is really interesting is this thing right here and apparently there were a lot of scientists a lot of
astronomers that were arguing as to whether this was just a jet coming out from the planetary nebula in the top
left corner it's actually an edge on galaxy and they were able to determine it's an
edge on galaxy because you can actually get spectral details from that as well and in the bottom right there's actually
a face on galaxy as well hidden into the nebula itself and these were all aspects
that we did not know were there with the southern ring nebula and then we get to the part that i was
really fascinated by because the instrument that did this is an instrument from canada it's what's
called the the near-infrared and slitless spectrograph
so wasp 96b is one of these exoplanets that we've looked at with the wide-angle
survey and this is an artist rendering of what we think it looks like and there's been four different transit studies of this
of this exoplanet and with transit studies what you want to do is you want to catch the planet as it moves between
you and the parent star now what's really lovely about wasp 96b is that the parent star wasp 96 is almost identical
to our sun in all ways it's a g-class star it's about the same size it's about the same age everything's about the same
but the planet 96b is unlike any planet in our solar system
it's 1.2 times the radius of jupiter so it's larger than jupiter
but its mass is actually smaller than the mass of saturn so it's a puffy hot jupiter it's also so
close that it does a full transit or a full orbit around its star in under
three and a half days so it's very hot it's very big it's not very dense and
it's very very close to its star so when we did all of these incredible transit studies of wasp 96b in the past
what we found was that there was this incredibly sharp amount of
sodium a little bit of lithium a little bit of potassium but a lot of sodium and very few clouds the cloud opacity is
negative here because there didn't seem to be any clouds on this exoplanet so we thought for for a really long time that
this was an exoplanet where we could actually see the full atmosphere and see
exactly what it's made of because there were no clouds there to be seen and there seemed to just be some heavy
metals well we thought it was cloud free because of the way in which those spectra were
really showing us the full amount of absorption not just a truncated version
so last month the james of space telescope put 6.4
hours examining the transit of 96b across wasp
96 they took a bunch of what's called reference baseline data which they can
then subtract off what they visualize while the planet blocks the starlight
and that allows them to see the absorption spectrum as peaks rather than valleys
now at the moment that the planet is just entering in front of the star and at the moment that is just leaving the
star any sunlight that gets blocked is being blocked by the atmosphere so if we can
do this nearest spectroscopy we can figure out what molecules might be
making up that atmosphere now up until now we're limited to the technology we can use from earth or from certain space
based telescopes and all of that was typically in the visual and the visual allows us to see really
well some atomic data but it doesn't allow us to see molecular data and when
we're looking at exoplanets we want to see hydrocarbons we want to see methane we want to see water
and so today they released this first nearest spectroscopic data of the transit of
wasp 96b and look at the amount of water lines that pop out
four different water line transitions were absorbing photons from wasp 96
before the light got to us and that gives us relatively clear
indications but the other thing that we found was that it actually has clouds wasp 96b
does seem to have cloud-like behavior which tells us that either it's a more
volatile atmosphere where sometimes there's clouds sometimes there's not or there are clouds and something else
was causing us to not see clouds in the visual when we can see the clouds in the infrared so now we have more data that
we can use to try to analyze our models of these hot jupiters within our solar system
or sorry within our galaxy our solar system my apologies so i didn't hit three hours i did almost
hit 30 minutes and i want to remind everyone that next week gsp 100 and i hope everybody will join
us for another week of incredible astronomy and uh thank you everyone
thank you so much that was uh that was amazing um i do have a question um
i would imagine that uh j west with all of its modern uh instrumentation although
that instrumentation was installed maybe 25 or 30 years ago okay as it got
characterized into the spacecraft uh it must be so much more productive than
hubble space telescope it does seem to be especially because you can you not only use it 24 7 but
because it's cooled at such a constant rate you always have the exact same thermal fluctuations uh the random noise
that you subtract off is incredibly predictable the other thing to recognize is and i
was i was spending a lot of time trying to understand james webb a couple of years ago when we were first looking at
the possible launch it wasn't that it was technology that we had 25 years ago 25 years ago they came
up with what they wanted to have happen with this telescope and then they said okay now what exists and what do we have
to invent now and so much of what we did was actually you know the solar shields the technology
for for folding up the telescope the actual film that goes on top of the secondary to protect it the gold foil
being used instead of aluminum or anything else you know the the materials that were used to try to keep the
cameras from suffering from cosmic radiation and the cameras themselves all of that
had to be invented once it was determined what we wanted them to do wow
and that's just you know that's a feat of science of engineering and of this shared horizons it was a it was a
international effort to say this is what we want this telescope to be able to do
how do we make this happen what do we need that doesn't exist now and let's figure out how to make this
work and now all of these different technologies are now available in private industry and even in public
areas here on earth and so we all benefit from this and this is where you know i i actually got flustered when i
saw some of the comments coming out well you know what's he doing what's biden doing you know sharing an image there's
so many more important things to happen it's there's an element of wonder of
curiosity that drives the human race and we all benefit from it so it really has
to be part of our day-to-day not just this thing that we occasionally celebrate
right yes but i do i do wish that uh they had had uh professor kareem jaffar there
with them uh to walk us through that first image so this is this is what we actually talked
about amazed as as we all were you know we talked about this on space oddities the one thing missing last night was
having a science communicator there to to answer some of the questions that people had and even that that president
biden seemed to have like you know having somebody there to to give why this was so monumental and make sure
that that was first you know it was foremost in everybody's minds is there's something that is here that will make
not just our knowledge and our understanding of the universe better but also technologies on earth that we can use
now that we've tested out in the extremes of cold space that's right yeah i would say that these
kinds of uh grand missions that cost billions of dollars is money very well spent because
we'll have that spacecraft hopefully for a very long time but beyond that the spin-off technology is priceless so
absolutely okay well karine thank you so much thank
you for making that presentation and i think everybody loved it uh
it's certainly well this whole program you're going to want to watch again because there's a lot of
information coming at you here up next is maxi flares uh
from argentina maxie has shown us what you can do with small telescopes with
modest equipment he is really a guy that among some of his friends in argentina
that totally pushed the limits of what you can do with your astronomy here maxie thanks for coming on to the 99th
global star party thank you scott hi everyone good night and well
i really i really i'm really very excited for
the pictures i think you too of the james webb telescope you know i
saw the transmission yesterday of the president biden and nasa
and wow it was don't mind and today
it was almost at the middle of the day here in argentina and i was working and i say oh man
they're going to show the pictures and i'm working and i couldn't see it and well
anyway i i figured out and of course chatting with my friends nico
another from whatsapp groups and everything we we were very very excited and well
you know uh my presentation for today is is going to be let me show you
it's going to be what i've been doing this
weekends ago last weekend i think it was a really cold night and let me share my screen
okay do you see it yes excellent so
the last weekend i went to alberti to the observatory
and you know it was a really winter afternoon that the sun was really
comfortable and the night it wasn't it was really really
cold but i we have a really good chance to to do
some deep sky pictures uh i want to
to do some sculpture galaxy the the
pan stars ke2 and this is
the another view preparing everything this is ariel another friend here's the the school they are
continuing with the reconstruction and
yeah we went doing some prepared chatting checking some
jokes so my my goal was
like i said the sculpture galaxy but i started with a comet and like it's
in my background here is the the pan stars
k2 this is a one hour exposure stacked and
processed in pixel size you can see the the core the nucleus and the coma and the collar
detail of the of the comet
and well i
then i i want to er to to see what kind of galaxies that i
wait for before a sculpture so i i thought that i can do this
place in i think it was a year ago the ngc
4567 you know it's a really good place
to with too many galaxies but
i have some trees and there and they say okay now i have to go another way
so i went to the ngc 7582
this is the the
quartet of gurus uh
this is what i get in the in the final second process
you know when i did this i already did this place here in my home
but the colors of the galaxies and the background it wasn't the same
and you know this was last sunday not not this the another one
and uh when i saw yesterday the
the picture of the james webb telescope it reminds me what i did you know with
all this field of view completely inside of galaxies of course this is not mine is the james webb
but now i'm about to ask you about that [Laughter]
no well uh this field of view is like well i want to take pictures from this
place but for example it's going to be i think more like this
you know we have a lot of galaxy clusters
and of course i cannot have that information but or details
but yeah where's the warp galaxies yeah i don't see all the i don't see the
gravitational lensing no i don't know no i think it's going to be i'm just
kidding so well when i i saw these pictures i
really get emotional because i was
watching something like i was always dreamed to do
in my entire childhood life and of course i cannot
a reach to the chainful details but
with a regular equipment i can do
a one percent one percent of that and it really worked for me because
it's it's like it's almost you can touch it you know
it's and of course the colors are the details and the entire worlds nebulous
uh they are going to be in all these galaxies in this field of view and you
know you can't image in the entire universe the vast universe
so well this is uh what i've been doing and then i went to the sculpture galaxy you know
i was taking pictures of three minutes at gain 110 [Music]
degrees minus celsius this is a single picture and when i get
stuck and process this is one
i get this picture it's not the james webb tells me but i
have something beautiful that's incredible
thank you guys it makes it beautiful you've got light from those light years away
and you've got structure it never has to be perfect that's what
those other instruments are for to get more details but just with your modest setup
you've got all of that this isn't this isn't someone just pointing a camera at a sky and click and uh if it were easy a
lot more people would do it you can even tell apart the arms like it is incredible the resolution you got star
forming regions the h2 there you see some nebula in there uh it's pretty rich
even in the in the edge of the galaxy here for example i i still watching
clouds and behind it and here too you know
and wow i really really get excited well
of course here i think this those nebula with those
fancy colors and oh man i i i was
like a jumping will in one leg
and well in the field of view you have a lot of galaxies they are
really behind here for example here's another one
here another one now there's a lot and well some friends say to me that this is
going to i have to print it and doing some to put it in my wall
like a picture absolutely so this was the goal for that night i've been doing
taking pictures for almost three hours of this object i went to sleep i
i remember when i was sleeping illusion i i love
hallucinating hallucinating hallucinating for like the cold weather
when i was dreaming you know i thought there was there somebody hit me oh but it was the code
that was hard it was awful but anyway oh um no i i didn't download the
picture but we have a we don't have condensation what of the weather
because is gets ice instantly my
my my window of the cars are full of ice and the the telescope this
has this crispy ice they're going up
so um for finish and actually before you go on
what was your telescope camera combination like for that right now right now i'm having let me
show you this picture okay well this is an nx eq 5 pro
i have the the eq mode connected all to my scr uh
zwo scr plus okay and here i can control with my cell phone or
if i go with some good wi-fi with my computer uh
my principal a camera this is a cwo a 533
mc because this is color here i have inside of the
user the the coma corrector of course this is the back focus that i
have right and here i have a zwo 290
mm because this is monochrome camera and this is a regular
a finder a finder star that i put
for take an auto guider and well now i also
i received the the cwo aff focuser okay because
to to do some really good focus when i inside or when i have to do this
particularly tiny focus because it's really really
yeah yeah even when it's cold yes you don't want to touch anything and
well so well basically this is a cup that i did with this neoprene
a thin cover right and staple
here you can see the staple there yeah yes of course it's really
cheap right and of course the the cables but this is all
what i do and the telescope is eight inch an eight inch and f4
um four yes and and you know i don't need even the
computer using this i can only connect and i can do the polar alignment i can do the focus i can
a use it the principal camera or maybe the
the secondary i can do the auto guide all in this and even i can
it has a little a sky
stellarium you know to find some objects and select them and say go to there and the
amount goes you know and even you can connect it to the an explorer scientific
a 100 ax of 100 because it stays in the the
settings so it's really really open for almost the the known mounts but
of course the camera it has to be zw that's that's really tough if um
not if you are using a dcr you can connect the
the intervalometer i think i don't know how to do it because i have an old camera and it doesn't have that
but well this is my my gear for now and also i have another little more
telescopes but this is what i do here
uh and for finish i uh of course to a karim
did some conversations of the james webster scope pictures and i want to do the same with
my own and the james webb you know this is what i what i call the
a caring name and the gabriela mr
and the james webb telesco space telescope so this is basically the the calina
nebula the enchanter in the nebula that i did last may
and here at the bob you can see sorry
you can see this square and this is the field of view that i did with my telescope of the same region you
can see here is the gabriella mistral because it has the the shape of this writer from chile
and this a really good star cluster and
sorry here is the square and here's the the star cluster doing
with my 8 inches telescope and you can see
here this rectangular
that is all the field of view of the change web telescope practically upload
today and when i when i compare this to the james webb
you know it's going to be like this
it's [Laughter] yeah this is my goal
yeah that's the new goal yeah like i hope someday i can have some kind of change work telescope but
now it's a joke but you can see here the entire details that this equipment
has it and you know this is just the starting in this new area so
like we say another and like we said in another gsp
we are in the golden age of astronomy astrophotography and science
so [Music] you know i i'm really grateful to to live in this area even
for all the things that happen in our world but and of course the the humanity
has a feel a view from the to the our
horizons like a species with this so thanks everybody hey i'm maxine i'm
really grateful to be here and of course i i will be in the 100 event the next
week uh like with you i hope that you can join us too
because you know 100 events of this gsp that's a lot
wow that's a lot of hours and chatting about it you know i'm really grateful for
know all of you the invitation of the first time that you
made me to be here and you know i i
now i know that i have really good friends in astronomy and not astronomy
you know in some places in in this little world around the world
around the world that's right so i'm really grateful uh and of course of the
audience that's always support us and well of course to you scott to invite me
here thank you thank you it's been a special honor for us to have you on
maxi so thank you so much thank you well uh we are going to stay down in
argentina for a little while here we're going to uh meet up with caesar brolo and his son
augustine and uh caesar you want to come on to uh global star party
yeah yes there we are
i think it bears important to say because a lot of us that are in the northern hemisphere if you may be watching from whatever
site or you're um watching this after it's played um
you have to understand the southern hemisphere is now in winter and it's cold some of us may not realize it because
we're we're in 90 degree weather 80 degree weather yes now here
yes we share horizons but on the southern part of the horizon it is cold now and
uh everything will even itself out our january and february it's warm so
there's uh you know i think that's worth uh mentioning so those of us that are in the northern hemisphere and we see cesar
with this big coat on and we're wondering what's going on we can get we can give you some
cold weather to feel good we will get plenty all right we know we will get hit when it is our
turn to face away from the sun we will get plenty that's right let me uh go
ahead cesar [Music] hi how are you hi everyone uh
well here i am in the balcony uh as i can see yes 10 10 degrees now this is
beautiful nice the permanent is is for hunter for astronomers amateur
astronomers is that sometimes you say okay 12 degrees it's not horrible it's okay 10 degrees
but you are staying in a place it's the same that the people that make hunting
yes with with awaiting something well we we made the same normally very
many amateur astronomers and look that the
people that make hunting in winter use like for for the weather
and really it's something that because something that you need because you
you are going to be quiet stay in a place and your body
going to to to feel more more
uh cold and like me now especially in my hands but you know you need your hands
because the the telescopes are sometimes have parts that
don't was designed to to use um gloves and
you know that that is a program that many times we have um
but we enjoy really we enjoy for the people that say okay these crazy people no no but really we enjoy because they
when you have the lights like maxi that
maybe make a picture like a change wave of nine hours of expositions
uh because have a great uh great place with the great uh skies
no in the city of chile but but
in a place that he have maybe
15 minutes driving he he can he can reach the rural
skies like many people but in the city maybe we need to go to the maxi house
two hours driving and uh expecting an assad or you know
any any time anytime yes
and and here the tools that we have to catch part of
the skies are really narrow the possibilities but um
in long focal telescopes or sometimes
in small apertures for for apochromatic telescope we we can reach a great part
of the sky made different astronomy astrophotography
um really we we have we have fun
something that i i can show you now just a little because uh
this telescope is maybe my idea tonight was uh use uh yeah the
exodus by exodus 100 with a a white telescope why filter let's go to
this uh it's a entry-level telescope that's very nice it's a it's a [Music]
four and a half inches telescope f5 very short focus
but i i couldn't i i returned very very
late of my work and i don't have time to to make uh the setup of another telescope next
time next time i promise because i i try it and it's beautiful for for the city
too and uh well i can show you maybe i have in my
telescope and an area of of a global cluster
very let me check if first of all if i have something
to show in my in my field view my telescope and i'll
share i'll share the the screen
um it's it's not very impressive no
because i i don't have the target about the about the cluster that i need
to show it's only a i i'll show you but it's a poor part of the sky it's near to the cluster but
it's not the cluster that the the ngc three three three five i think
but a shared
it's screen black but i can check i can i can try if i have something
in the field um
no no well but
but for tonight maybe later i can
before my my son augustine can show you
pictures i try i try to make something with omega centauri
okay i try but you know sometimes for a bigger telescope is something that
is not easy i don't have the time it's important to say we need time to make the setup correctly
and today tonight i i didn't uh yeah you can't rush these things you
cannot write yes yes we can show to the people that sometimes we can fake
right i'm introducing to my my my
son i would say well sometimes uh last saturday um
we went today the roof of my
tower and with the same the same telescope and
we made two different pictures of the classic
the classic object of of
winter here somewhere in north america of
i would think especially he took the pictures uh because i'm you know i i
i assembled the setup i put the the first part of the polar alignment
but agustin finished the process made a very precise polar alignment
using an application that the name is
bhd to have a tool to make uh for example
when you have for the people that maybe don't know this telescope is the same
that uh near to two meter focal focus
large telescope and you have the same problems that
you need to be precise to make the polar alignment and
to make maybe two or three minutes exposure each of each legs
um well something that today it's for the people more
um more available to to to have
have a lot of different tools to align very precisely
the polar alignment to to have uh long exposure pictures
because we make uh like today that we was talking about about the
the change web telescope with their amazing
uh also i don't need i i i don't have words to say
my impressions that i had for the pictures not only the pictures not only the image
something that karen explained tonight uh dr karin that
is the the opening to science of the these potential
optics this is because maybe we can make a beautiful images that are awesome that
are impressive but this this
made something potentially that it's opening to the science
uh a world and universe of of possibilities
because um as maxis say he said okay i have something similar
i feel of galaxies and i love the maxi pictures because it's a real a feel
of of uh galaxies and when you have to have or start going
to another telescope bigger and bigger professional telescope the steps and you
have for example when you
use large focused telescope for example now
um talking about instruments
the vixx and telescope have near two meters long and the telecom that you have in your
back spot and it's another universe it's another area
where you can go to the core of the of the nebula for example
and you are yes this is the same like like this in another design but
but when you go when you go to to to change the the
things about the the field of view or uh you know
the focal length the you can get different effects
um because you have the magic of different optics
um well it's something that that is is uh
amazing because we choose for example from the city make
you sing yeah i love it i love it you you grab the
baby yeah yeah yes okay you're talking about i appreciate it
yeah yeah my god yeah no yes i need one i need one it's a very lightweight
telescope as well you know but nice one look look i will thin our next telescope
being home because we need one to you know to try okay can you send me that one
yes another one for maxi yeah yes absolutely i love
i i grow with uh schmidt casserole and telescope
and i love the apo telescopes because it's beautiful but
i felt i feel very in my home using very long
focal distance and it's something that is a challenge because you don't
all for example tonight the win come on it's something that that is
something to to fight um but but really is another phase of
astronomy and it's something that that really we love we love the this one about about
optics the wide the the wider
field of view in the sensor the another one with a
small part something that i miss is
who is which is the the field of each camera
of the james webb telescope because somebody say no no it's like like a piece of sun
you know in in your hand less than one minute only no no it's
impossible uh because i i read this in the paper it said no no these people don't understand
nothing but i i know that have a really really small wild camera but i think that
if somebody knows um the difference why
of each sensor of each camera it will be very appreciated by me because
this is something that that i'm very interested to know well
i introduced again because it's not his first uh
global star party to a routine i would then make all that i do hey what's up
i will tell you is good for process it matches but actually he's going to to
to go to to finish the the the small adjustment and take the
pictures take the flats and he's going to to use more the complete history of
the picture or you know have made her have a
more complete part of the action maybe well okay
i think that he's he deserves uh explain the pictures because he made
mostly the most part of of this he have two pictures to show and the process you know by picks
inside you know techniques stuff
thank you very much scott thank you cesar thank you and welcome to global star party augustine hello thank
you how's it going it's going great it's going great we are still in the glow and the uh the
afterglow of uh witnessing some of the most amazing astrophotography ever made
from the james webb space telescope but uh it's still a thrill to see
uh incredible amateur astrophotography so and it always yeah so
yeah yeah the amateur it's a a constant fight against uh
this random [Music] things that can happen to the to the
the moment of doing you know the taking of the photos sure because
talking about this my dad when he when he set up the the telescope with the mount and
everything um it's been so long since we last used that mount
the ccm that i completely forgot how to you know how to
do anything so yeah when when he first set it up i was in my room
and then well i decided to go up to the terrace and
well we find out because i always i'm just like that you know like trying
to uh i always find problems everywhere
it's maybe it's a course it's a bless i don't know um yeah i find problems everywhere so
when we when i just when i i arrived there we started talking and i find
that the polar alignment was i first thought i mean it's kind of off
but then we checked with the on the hand control uh you have a
setting that uh it will tell you the the actual uh
error in each axis right so it was about a 15 degree error
on on each axis which is more than the uh
declination can can correct because i think the declination the the
physical movement and that the mount can do it's about uh nine degrees to each
side to each side so yeah we had to physically physically lift the tripod
and move it i see literally like that we just yes this is why we don't use uh explore
scientific mounts i know
sorry i just kind of think it happened with any mount i know yeah yeah yeah i've had my own
experience you know of course i've uh i like like your father i sold all kinds
of mounts and and there's so much good equipment out there but the point is is that you have to
like like if you're going to be a musician you have a guitar you have to practice with that guitar really all the
time yeah yeah good at it you know so and if you switch equipment or whatever then that becomes a big challenge too so
yeah yeah it was it was a fun moment uh then we started to try doing the
go-to doing the for alignment the polar alignment never ended to be uh
never ended to be actually like perfect uh but eventually we reached a minute
error which is usable i mean for the conditions in which we were
they are almost perfect so well that's done
um we did all the setup that that took a whole
uh three hours maybe like we started taking photos about
two in the morning like yeah wait wait too long
yes it took way too long uh were you having fun now were you having
yeah yeah okay i mean i mean the the funny thing about this is that um
you you actually have fun uh like the suffering makes you have fun
it's weird it's like we are masochists like why we do this yeah that's true
it's like golfing if you hear people playing all the time while they're golfing but they're having the time of
their life right so yeah but i mean it's it's so fun to like just shoot the ball but yeah now you have to go and travel
all the way to the 100 yards you just yeah so
we we we we did that we it took that not many hours one i think
maybe two hours and [Music] yeah uh what i said that the about the
three minutes error in each axis um that was using the uh celestrons in
built-in uh polar alignment thingy uh but then
there's this program that my dad mentioned which is phd2 ph guiding
which every everyone should use if they are using something else well i don't know but this one is like the
software to go to um it has a polar alignment by drift
so what does this this mean somehow uh this software calculates
first you have to select a star from the
guide telescope camera obviously and while you select this star and uh
it starts making little little movements and also measures the drift and it will draw a
vector on the image that tells you where you should uh move
that star to to counter that drift so yeah we use that
yeah it's it's awesomely useful and first it's funny because you're when you
you you set up your tripod kind of kind of good using the
the south the south cross um here in the south we have a a cross
instead of the polaris like you guys right our star so the way we measure is we do
we grab the the longest axis of the cross and in the same direction that
it's pointing we we go three and a half times
and then we go straight down and that's the south the south uh polar um
not the earth's south south but the celestial south and yeah that's how we
measure the south the real one yes yeah so once we did that we we did all
everything else and uh when i wow wait what i wanted to say
which is really important is when you are doing a polar alignment
the idea is to use a star that is
away from the east and west
because of how how much will the like it's like a a factor
a multiplication factor if you are if you are no let me
dial it back for example it's like having precision if you grab a pencil by by its tail and
you try to draw that's right you will have very little precision so that's the idea
and yeah because i saw an explanation the other day that it was really useful
and once we we have all this setup i want to show you
uh well now comes the taking of the photos so what i want to show you is
the first thing related to taking the photos which is light pollution i want to show you how bad
the light pollution is in the area which we took it which i mean yeah
this this is in the buenos aires city uh inside the capital city
which is like um one mile from the river from the from
the the sea let me open the light pollution map
here i'm gonna share screen
to show you all the oh yeah okay oh this is from 2015 let me
change here let the the latest information okay so
if someone is used to the to the to the units if someone is
already familiar to the the the magnitude which is uh
magnitude divided by let me check okay
it's oh it doesn't say wait well you can see now i mean yeah it's
it's in the middle of the red which is the worst
okay well it doesn't say but it's a value around 7080 which which is a lot
it's as you can see in the middle of the the worst zone you can get
um so yeah we did uh
we are in the middle of the city and even with all of this
um we took some photos uh i'm okay i'm gonna tell you it was one
uh one and a half minutes for each exposure and we did about 20 photos for each one
uh we took photos of m20 and m8 this being
the thriffi nebula and the lagoon nebula and
here you have the final images that i that were
i think i forgot to add the i forgot to add the calibration frames
to this one but yeah so the final processed image is this one
okay i mean obviously you can see that everything that is not the brightest
part of the nebula it's covered by light pollution
because this is not the the sky really this is literally all that uh
that light bouncing back and forth and yeah i mean
it you don't have flat fields or dark frames or i did take
let me see i think for this photo yeah i think i did
because i think i forgot for one of for one of them the thing is one thing i found is that the amount of
flat frames i took was not enough ah yeah
i don't know why but what what i saw is that let me let me show you it's amazing
you can get that kind of nebulosity and detail from such a horribly really light polluted area yeah it is
it's i'm impressed i'm also impressed let me let me show you the master flat
that i took
i'm gonna stretch it and yeah you see nothing
so in in the in the first stretching you see nothing but if i go further
you also see nothing let's go even further i'm gonna check this out process
histogram so
okay now you're starting to see yeah here you can starting to see the first like uh
dust that's okay well that was that was way too much but yeah you can see it's right
right here and uh yeah now with the resolution it gets
but you can see it in on the top right and then on the bottom left you can see some also
grouped up and yeah uh so the the question is do you need
exposure time do you just need a [Music] amount of flat frames
uh this is what i'm gonna try to figure out because the amount that i took it was 15
15 flat frames with a short exposure time using the same iso
than the light frames so the question is for some if someone
wants to know how to take flat frames uh well the the the first thing you have
to do is put a white uh white translucent uh
material on the on the front of the telescope
and take a photo that will let light will let light in in a very
uniform way the thing is well uh this happened and i
didn't get enough information of the dust in the sensor and
yeah the only thing i i it was of use is the divinity because the flat frames gives
you uh information about the vignetting that the the circular uh
yeah the the pattern of illumination of the yeah because you are you are going with a
circle um shape in a rectangular sensor and it will obviously
can generate somebody so yeah i want to show the other one which is and i like to know i like to
to to so again to see again the the details of the
center of the new england that this was amazing for me was something that that
is not a regular thing the the details inside m a and m
31 i forgot to take the let me i'm gonna do this fast
but yeah the i didn't finish this the process because
of this problem with the flat frames uh i'm gonna i'm gonna retake those flat
frames until i i get a useful information
because even even when i even when i hear you have
even when i process see you can you see this black yeah this is
oh it's horrible yeah so yeah this is a horrible but
yeah i know yes it's there but yeah but for me i am i'm most you at the center
yes sure for me the the the details in the center of of both nebulas are are really
amazing and have because the sensor i can clean the sensor no problem i have the owner of
the laboratory but but it's interesting to know that i was
synthesized about how many how many exposure you need to make or
about flats and is it is sometimes it's not enough the
information or ever ever you need to make a
trial try and try again to make it trial and error
yeah yes i i saw that the pictures have not a lot of color are more flats in
their their level of colors and yeah and knows one one good thing you could tell
if you keep working with it you know you keep taking more data and keep working yes you can you can get there
yeah sure what i found is that actually the uh the color of the stars it's actually a
very rich color because here in the trifid nebula you can see here that you have
three tones in a very close you know here you have well but here for example
on this preview this is a very orange star and i didn't
even process this image so yeah at least the color of the stars is there
maybe not not that much uh the velocity you know all the dust
but we are getting there it's this is about 30 minutes of exposure
with this amount of light pollution so yeah if anyone that lives in a
a like polluted city it's good that he knows that
he will be able to take like at least some average of photos
like this like you can actually do it
for example you know if you live in new york or or chicago or i don't know any any big city
that has like crazy amount of light
do you have a picture maybe i don't know if you have in your in your computer or with an
ed ipo periscope that you took last year of mhm
that might be possible
yes
yeah no but this is another one but it's with the camera
[Music]
yeah this is uh 480 millimeters which is the the zoom lens that we have
it's it's from the same this is here you have the both the nebulas and
here you have this the real sensation of the change of
field yeah yeah i don't have the an 80 millimeters
photo i mean i'm in a photo with the with the with that that too
but yeah i mean what i wanted to show is the possibilities that that you can
actually take photos from like the the brightest objects
if you have some i think i don't know the the magnitude like the average magnitude of
m8 or m20 but as you can see if you have about the same light
pollution level you are completely able
with only 30 minutes of exposure you are able to uh to reach
this level of detail that's what i wanted to to show like it's it's
it's very possible uh it's beautiful it's
yeah i know that you can get it and uh i think it's very inspiring that you have what you're showing here and it's
good to show it's good to show uh you know what it takes to get uh to the
to the next level you know so yeah obviously uh
jumping from not being able to do guiding and
to being able to be to use some guiding it's obviously a very
big jump because you go from taking you go from needing to take about
hundreds of photos of 30 seconds to just go in and take
five photos of five minutes each and that will change the
the information in the photo completely so this is one of the jumps we made because
now we are able to guide which was the thing that i was wanting for for
a very long time because you know it's it's not the easiest to have
one camera dedicated to the guiding and also having a camera dedicating to the photography
because you know money always is an issue but it's that's the thing that we all
struggle with but yeah with guiding and another thing that they use
was 400 is iso 400 yeah 400 iso
400 iso with a digital with a canon 600d which is kind of an
old camera but it's a dc dslr but very old enough for they will come
out yeah so nothing really yeah equipment right so yeah
yeah kind of outdated but it works i mean it's the the the quality of the sensor is enough
right it's really enough but my dad needs to clean the sensor
yeah yeah all this all these things my work my work yeah just
it's a whole new star it's a death star somebody knows over the sensor
you are all right well gentlemen we're going to have to
wrap this one up and go to our 10 minute break we're running about half an hour behind but it's been fascinating
and we love having you on so uh augustine you'll have to
uh join global star party more often uh yeah a lot of our audience remembers you
and they love they love that you're here so excellent okay and see you scott bye bye
thank you very much guys bye-bye to everyone yep enjoy so we are going to take a uh 10
minute break uh right now and uh um
we are uh coming back with uh in our second
session with uh martial asusa from brazil uh daniel higgins from master world tv
dt good tom from nepal and
connell richards and bob fugate and there may be another you know a couple more surprises here and there as we have
people uh actually backstage with us so
anyhow thanks for thanks for watching the first half of the 99th global star party and stay tuned
through this intermission for the second half
who's going to be first today you are you just no no in the chat
oh tariq tarek is going to be first yeah he won you're right
there [Music]
your presentation curry because you explain a lot of things about about the
the change web telescope how that made the image
this is something that that we need because it's it's a it's a gate to the science a new gate to the science the
telescope is amazing i know that they make dementia beautiful but
it is it's amazing the possibilities well thank you
you deserve that well as you all can see my background
changed uh inspired by uh kareem i decided to find my own favorite
image of um from the jwst nice dipty uh naveen is
closer to you he's not exactly there but he's getting closer he's in india now okay
oh wow
we're happy to be back and i'm looking forward to figuring out how i will finagle my
schedule to make sure i can attend if not present for the 100th yeah you
can't be missing next week there adrian i can't be missing next week so something
i uh i have my schedule right here so worst case you do what i did uh about a
month and a half back you just record yourself doing a 10 minute segment and send it to scott in advance but it's
better to be here in person yeah so i'm actually going to be sharing
with um some grade school kids some solar viewing on that day
so i'm sorry daniel uh i just pictured you as a frog uh with what's up
[Laughter] oh yeah there he's in yeah you're in on
both sides uh-oh i don't think we can hear you daniel
that's a good thing to fix before he has to go on yeah
either that or scott did that on purpose and he's actually muted both of us as well and we're just talking to each other
that's quite possible i'm sure
oh alfred um there there's a lot of people asked
spouting nonsense and yeah i tend to ignore it and i it's just it's not right
now we hear you ah there we go
we've uh yeah even before these images today
were released there were there were a few channels on youtube of uh
james webb space telescope images um that were really either hubble images
or taken from other another source and
i saw a couple of posts because they ended up in my feed and i did my best to report them as
sending uh false information that's about all you can do exactly is uh just if you if they're in
your feed and you want to do something about it report them as report the video is uh spreading false
information and hope that the powers that be can help you you know help take those videos down
i know a lot a lot of people with the images freely released um
are going to be using those for likes and you know subscribes and everything else
it's just the nature of the beast that we're in with social media which is why shows
like this are on to uh we bring on daniel higgins to tell you all the truth
about what's really going on you know just just watch you know watch shows that
have the backing of a kareem astro an astronomy professor
you have dr souza on astronomy professor dr higgins
and yeah i'm trying to figure out where i got all these promotions
bing promotion adrian is giving out honorary doctorates from the university of bradley
nice thank you i am honored they're so and i see uh a freed i see i
think it's pronounced afraid i'm not sure but i see that you know you've reported it how many astronomers work
for youtube um so there are like nasa does have an
official page and anything that comes out of that esl
eso has um an official page all the you know there's
there are things it's out there and you just have to look you have to look at them and you can sort of tell when
it's uh it could be real information not always not always uh it's it's a
valid concern and it's a question of whether they go to somebody with an authority to give uh to give some that's
right yeah if they're sometimes you have to you say okay this is what they're saying
so you look it up and you see if you see if it's being repeated
in in different astronomy um streams like this one
or yeah you know other streams you you see if there's something consistent now if
there's you know if there's something out there that's doing something on a religious or
you know a different spectrum you're kind of on your own as to whether you want to believe
um you know if we go down a religious path now we'll leave we'll leave that out
from from right the gsps you've got there are some legitimate faith in science there's a
legitimate faith in science uh pages you can even go to for that but um
as far as you know a pure science um
as far as that goes after a while to me i think the source
tends to speak for itself there's an air of sharing with humanity all of these
things that we're seeing versus if you've got someone who's sort of
pointing at themselves as you know as the one who has the information then
you then you begin to question it and uh happy belated birthday to naveen to set
the stage for part two happy happy belated yeah yeah happy belated birthday
i'm i'm halting the uh the timer here because of all this okay guys we're
gonna get started again but uh yeah naveen is uh uh visiting i think family in india right now so
hope you're having a good time and uh glad you're watching global star party
hello everyone it's bob fugate from albuquerque new mexico congratulations to the global star party
on achieving 100 exciting episodes please keep up the great work thank you
howdy scott explore alliance astronomical league and esteemed global star party friends this
is cameron from camp astronomy wishing you all a hearty congratulations on our 100th global star party keep looking up
and enjoy the journey cheers hey folks sean here from visibledark on
youtube invisibledark.ca on the web just want to send a big congratulations to scott and explore scientific on the
100th episode of the global star party fantastic stuff keep up the great work here's to 100 more
this is karine jaffer explorer alliance ambassador and rasc montreal central public events coordinator i'm coming to
you under a strawberry full moon and i'm looking forward to a couple of weeks of waning moon and dark skies i'm looking
even more forward to the 100th global star party coming soon to a screen near you
[Music]
[Music]
foreign [Music]
[Laughter] [Music]
[Music]
[Music]
hi everyone dan higgins here from astroworld tv and as one of the newest presenters of gsp i'd like to send a
congratulations to scott explore alliance and all the presenters of
global star party for 100 episodes of the show so outstanding job thank you so
much for having the perseverance of doing this and relaying all the information that everybody does every
week so thank you so much thank you for allowing me to be a part and as always remember to keep imaging keep educating
and clear skies we'll see you soon
so thank you everybody for uh you know all the props for uh 100th anniversary or
900th anniversary 100th show global star party that will happen next week on
tuesday so it is a milestone uh i can hardly believe it's happened myself but um scott are you feeling like
we've aged you 100 years no not at all no no i love this i really do i i
learned so much from global star party with all you know i don't know how many
100 hours of of information that has come across uh since we started doing
all this stuff you know and and you know dan higgins can uh concur with something like that because he runs shows
and you just you just get this incredible um you know
uh all this information compacted down into uh you know a a
a short amount of time but it's years and years and years of experience you know and passion and interest and all
the rest of it and people they do bring their game on when they're when they're live and uh uh you know having to
present in front of a you know a live audience it just does it to you i don't know but um
that you could tell from me that i don't really do i don't have a script guys so
unscripted is good it is very unscripted unscripted is good yeah yeah yeah
but uh uh up next is uh we're going to go from argentina back up to brazil uh
and meet up with marcelo souza who is also a professor of astronomy and
physics uh and uh he and i have been working together to
get the next issue of sky's up magazine out which he is the uh editor of that magazine so
marcelo thanks for coming on to global star party it's been uh it's been a couple of weeks so it's it's great to
see you yeah it's quite high all the people that participate congratulations to you and
they are all the participants of the global staff part and also my colleagues here that
participate in many of the editions 100
editions is something fantastic and we are talking about science that is very
important today and i i i will share something
first here's something that's very curious i don't know if someone already talked about this
here is the home page of your group and here is tommyhang
and now uh today is july 12th
and the in new york you have something that they call them manhattan
that i think that's happening again today that's what i i don't know if i i read
in some place let's see if you have clouds that are or isn't possible to see but something to think about because
maybe one day they will find these buildings and they from
between these buildings you can see the sunset or the sun
rise and then they can imagine that they built for this reason right like we
imagined about the stony hang and it is fantastic that you will see so many people
that's a in disappear to go to these streets in manhattan to to city
i i don't know if you need sunrise at sunset that they are seeing up but it
happens every july 11 and july
12 today there is something that you can think about
and another thing that i would like to show is this i think i know that many people right
shy this maze but something that is fantastic is that you see
the maze with spikes here right and the hawaii is amazing
from the james webb telescope have these six spikes
uh something that i i shall now have an article about this
that is important to know that it is happens because of the
mirrors and the truss i will show now what this this is i
suggest to everyone that wants to know about these spikes
to read this article i will show part of the this article here but there is
something that can explain very well to everybody why you see these
spikes in the maze and we will continue to see stars with the spikes
they are diffraction spikes and they will continue to [Music]
how the stars that you see we have these spikes and something that's curious and they talk about this why galaxies
and the other objects don't have the spikes only stars in the
images of the james webb then i will show this then one of the
reasons that you have a 18 the james webb it's not on one mirror you have
eight individual segments that is uh corresponds to
the primary mirror of the james webb telescopes and the
it's very difficult to make it configuration that you have audi 18
mirrors these segments function so they are a single mirror
with your optical perfection this is very difficult to do here is a measure of this mirror you see
here the gaps between the mirrors
and it is necessary to compensate for the space between each segments
the edge and in particular the sharp corners of each segments job through imperfections induced by the
truth that's holding secondary mu in front of the mirror and individual variations both
across each segment and from segment to segments these are what they need to compensate to have good image
and here you have these two sets of mirrors right
j segments that you can see here image these are images from others but also our part of this maze most of
the images that i'm showing here are available in the article that i show in the beginning of the presentation
then these the a segments that you can see here
which are for the interior segments where five of the six hexagonal heads
will boil another mirror segments here five of these brothers
have contacts and near other mirrors and everyone
then the most one will leave a gap for light to be reflected inside onto the instruments here
then you have also the b segments here
that you have the b and the c here we tell the outside coordinates of the
hexagon shape it's honeycomb it's have three edges i have three edges here
db that's bother another mirror segments
but three edges here that comprise the outside body of
the primary mirror and the six segments also
which go between the b segments and the c we segmentary to go between the b
segments and process for edge yeah
that's about another mu the c one sorry i showed the b a c one
and four segments four borders here that connects here near the other mirrors and
but two adds that along with the b segments here
you find the outside border of the primary mirror
and the goal is to have each of 18 segments from a single plane together that has a
parabola shape and what is something fantastic
is that the variations in the plane of each mirror
should be right around approximately 20 nanometers for optimal performance is
something very difficult to imagine a plane that you have the difference in this plane
cannot be more than 20 nanometers so i'm thinking
that is difficult to make to imagine what is 20 nanometers
in these mirrors wow then here is a three panel animation
that shows difference between the 18 unaligned individual image those same
images after each segment had been read together conflict configured and then
the final image was individually made from all 18 of the
mir of the telescope space telescope mirrors had been stacked and co-added
together the pattern made by this death star known as nightmare
snowflake can be improved upon with better calibration then this is the
image that you see and it you can have a better image but
ever with these spikes i will show here this is a line
that you had the first image and from the james webb telescope that usd alignments
in maze you see these spikes here man there's diffraction spikes
and here you can see jurism here you have a second there is a mirror
here in zargo mirror nd murals with gaps and the last one is the james webb
telescope that you have the gaps between the 80 mirrors and they also have the truth is here
that supports the secondary mirror and these wires predicted in 2007
that this was the pattern of the image this was a prediction
that then you can see here the last one also
is what we have for the james webb telescope three supports here
right for the secondary mirror and this is what you expect for the image and it is what you
see something like this what can we can see something better yeah
but with the six spikes it's impossible don't have these spikes
then if people is imagine that you see stars like a dot
well like on a point it will not happen all the stars we will see like this with
these spikes but even if it is the amazing fantastic this is made of fantastic i saw a lot of
images today everybody saw them and they have the effects of the gravitational lens
have many things happen here because we are looking very far right
there will be a excellent opportunity for us to understand more the universe
and then other standard sauce that i i said before as their light is spread out
of a larger area on the sky as a result these spikes are no existence you don't have spikes in the
image of galaxies here only in stars that's a point right it's like a blood
as a result is packing since light arrives from more than just a point and that optical effect is effectively
equation outside that the extended object provides in
this region we have only spikes in the maze of the stars
like that you see from the demon's web telescope these are the amazing i
came back from the beginning to show again the reference is from this bigfink.com
and the it's a good article for if you would like to know who are you having my
image like this man with spikes let's see we are going to see many mages
now from james on telescopes and these stars will be with the spikes this is because you have an
exagon that is called purify 18 mirrors
mirrors and they also have the support for the secondary mirror and then there's your reason that you have these
spikes six packs this is what i'd say i would like to say today's question
thank you very much for the invitation however it is a great pleasure to be here
and now next next week you'll be celebrating the 100
[Music] program that is a fun task
thank you congratulations yes thank you and uh thanks for uh sharing uh this
webpage big think with our audience um i believe that uh many of those articles
maybe most of them are re written by ethan siegel and uh yes i don't i i forgot to
include here the name of the auto sorry i have here the the page opener
and then i'll share the page and then i'll say i'll share i'll show you
the alpha that's important just to say yeah who wrote it
uh i will sure i'll share here on a moment i will stop here and i'll share the
sorry for this mistake [Music] is here okay
okay he's here now i have tried to find here also
because it's not um what's happening oh i shared i
do wrong you are sorry is here i think that the mouse correct
yes is it even single yes yes
he's a great science communicator so um if uh you are
um because you're here we don't have like you can
yes i suggest to everyone to read because it's something that
everybody you see now the maze of james webb he starts out the star with the spikes and
if maybe someone i received a message asking me about this who is have these
stars have spikes and if they will show better images if you don't see
if it starts if not he spikes but it's not possible
right yeah it's a hard thing to explain it's a it is uh a cause of uh physics you know
so well good thank you so much
my pleasure yeah and uh let's see let's
pull that off and um we will uh come back to our next speaker here
um which is uh daniel higgins for master world tv
who so kindly um uh has appeared on many of our global star parties as of
recent and uh he has a fantastic program of his own devoted to astrophotography
for people of all levels so if you're getting into astrophotography you want to
uh you know interact with people that have a lot of knowledge but are willing to take you
from rank beginner to you know or if you're very advanced they know how to handle uh all of your
questions and so daniel uh you've got the stage dude how's it going tonight getting
the pen ultimate 100th episode i'm telling ya next week so right yeah
absolutely it's you know i i can't belie i mean i i only got into it i think my
first one was 88 so i'm very i'm a youngin here okay and uh you know and it's just i mean i
don't even know i you know i feel you because you know what you're on this you're on social media
every day every day every day so so so god bless you i mean you know i mean it's it's definitely
it's you know you said it before you know you you don't know you don't know it until you do it it
takes a lot to get this stuff together and it's not just the two or three hours that you see on the tv it's it's a lot
into it so i got to give give you and all the rest of the other uh presenters that have been doing it a lot you're right in there with us daniel
so it's uh um if you're doing educational outreach uh you are prepping a lot you know and
uh um you know you can get in the flow of it for sure um
but uh you know think thankfully there's always something going on there's always
something to talk about you know so and astronomy is just a fascinating subject
from every angle you look at it you know whether it's you know gear or you know um
exploration uh to just new discoveries to you know it just goes on and on and on just like the
universe so yeah and we're on we're all on cloud nine you know coming down from the big
problem that we had today absolutely and um you know that being i gotta i gotta
throw a quick plug in maybe one or two but um tomorrow if you guys or girls out there
that don't know or don't aren't watching the show or whatever you haven't heard about this yet tomorrow is
the eagle giveaway on astroworld oh wow so you gotta yeah
so it's a big deal tom bramwell from prima luche is gonna be on the entire show um and he's gonna be hanging out
with us and we're giving this eagle this eagle is sick scott it's crazy
it's tell me about it totally maxed out 64 giga ram
brand new 2 terabyte 980 samsung hard drive wi-fi six
and it's not red it's black what happened it's it's a black eagle
with red writing and uh tom bramwell did a lot of work putting this together uh for it it was a
love of his he wanted to see if he could do it and he did it and he gave he made one for himself and one for us to give
away and so there's only two of these in the world so uh so uh if you want in on this giveaway you only have a couple
more hours to sign up for and sign up for it on astroweb.com we have about a hundred and
twenty people in the giveaway on the wheel so it's it's a big deal so um you know come on
down and yeah that website was i i may or may not be signing up right now
uh who's speaking this is adrian hey i thought so adrian i'm not giving it to you
no no it's it's www.astroworldweb.com
yeah i'm going to put it on i'm putting it in chat yeah so just go there and there's a whole bunch we have a whole
tunnel oh you guys are all watching right now you need to sign up for this i see it
so um when you go down there's about six or seven i mean i have
i have so much stuff over here that i'm giving away i mean i can't even tell you how much
stuff i'm giving away all right look at that so we got we got three nanometer
optilongs we got planetary filters 2-inch lrgbs we got scopes that were given away we
got cameras that were given away so i mean it's a lot of stuff going on so and these are all people that are just
throwing stuff at us so so get on the daniel yes hi it's
it's kareem from montreal hi korea how are you doing are those of us from canada and nepal uh allowed to
participate uh canada yes and nepal i don't i'll
have to talk to tom about that but sign up anyway um you know did you get that deep d
yes getting everybody in nepal to sign up
well well it's one it's one sign up per household and i believe it or not i do
check the ipa addresses for everybody but um um it's one per household
this is awesome that you're doing this daniel this is really great you know and and it just gets it gets
astrophotography i mean this is a when all said and done
probably about a three thousand dollar computer and um for for this to cut and tom has and the guys
over prima luche filippo and omar and all the guys over there have been super gracious uh with this i
never thought of anything like so thank you to them but um it's tomorrow night
nine o'clock on astroworld tv on youtube so sign up and go check it out yeah so just
just so you know uh nepal has a population of 29.14 million people so
29. they all just sign up only one time yeah well that that you know it will
increase right everything's failing to have some shipping we may we for nepal we may have to work on the shipping deep d so uh you know we have to work on
something i'll work on something with tom i mean if you get it to if you can get it from italy which is where you
know yeah it shouldn't be a problem in the fall so well it's closer than we are
but it will be coming from california because it was made it was all the parts were brought in it was made in california so right now it's in the
states it's a small planet daniel i mean that you saw the pale blue dot it's tiny
i did i did and you know what the funny thing is i'm not just another pretty face
i was able to actually do some astrophotography
i have not shown a picture this is you're seeing it here on gsp
soul excuse screw it totally exclusive i don't show my pictures out to anybody adrian will tell you maxi will tell you
i don't show my pictures out but i was able to take some pictures and you know what except for the ones behind me that
those ones you see those are the same ones that have been there for like years so so so um i'll show you real quick
that you know i i i think uh i forget who augustine i think was talking about the light pollution and uh and how bad
it is where where he lives and you know and and then he said you mentioned something about new york so i kind of waited for my hand i mean actually
showing some pretty nice stuff so absolutely and you know and it's not i'm not going to show the same thing because
you know i i did use an nbz filter with this but i'll show you one what that's just
rgb that i took this year and one that was um narrowband that i
just took the other night um so let me see if i could share my screen here if i
could do let's see what zoom meeting i got a share screen share screen one
share okay so the first thing i want to show is this
is the um this is the first one of the first things that i did this year um this is
lrgb from bordeal 8. um m101 yeah
that's very impressive you know from my backyard in nassau county long island um
i think the i think the the local um sky quality meter the last time i did it
was like a 17.8 if i remember right so uh it's it's pretty ugly so so that's
uh m101 uh that's about five or six hours
um that's it not a lot of data i just wanted to see if i could do anything with uh lrgb beautiful image long island
it turned out pretty pretty good if i got a lot more data out of it i think i could get a lot more out of it but um i
i for those of you that follow the show i just was able to acquire a new telescope
um i purchased an astrophysics scope um and i got a 130 starfire so i'm
looking forward to trying that the other one this one is um
this one is uh the dumbbell nebula and it's a little
it's a little over saturated for my taste again but just so you know this is
about an hour worth of data with an nbz um in my backyard an hour and a half i
think it was um in the backyard nbc and um
uh right from borderlate right in my backyard and again it is now been but you gotta remember what was going on
also i got o3 data coming in right from the nbz and it was almost a full moon
so um think about that for a second um again i over saturated a little bit and
this is literally this process that i did on this i timed it i did this
process in 12 minutes so there is no masking no nothing i didn't do anything
with this picture i just wanted to see what i got so um that came out pretty good i was just so
happy that i started to get the the wings detail of the dumbbell
right oh yeah in there so with a lot more data actually i
totally the stars are too hot the nebula is too hot everything's too hot but um i just want to see what i can bring out of
it right um [Music] and i just got back from cherry springs
how was that it it was good we missed you i saw your buddy up there yeah yeah so you got to
meet sheldon yeah and i knocked on the door i said scott and now he's not here i was like who are you
so so uh so uh yeah i was able to see uh scott and i took these pictures this is
about that's about three hours look at that
from cherry springs very nice um that cherry springs has some pretty dark skies though that's mortal too
okay um so border two skies and this was taken with a red cat
and a just the um 2600 the red cat uh with an l pro
uh not that i needed it but the l pro uh light pollution filter but um but that came out really well
yeah and the last one that i'll actually show is this guy
and that's m106 um and uh that's nice yeah that i i'm going
back to cherry springs um at the end of the week with a bunch of people from astroworld actually
actually at the end of the month i'm sorry not the end of the week the end of the month with a bunch of people from astroworld we have about 10 people going
and um it's it's uh i plan on dumping a hole but whatever
however long they're gonna put the rest of it in data on this on this object just to get some more um and uh we'll
see because i had a nice the reason why this is cropped in so much i must have gotten a
light splash from the moon or something there was if i i don't know if i could show you real quick um
and let's see if i could find a file open uh it picks it for do i have it here yeah
m106 and um get a splash from the moon because they
discovered water there i'm sorry that's a bad dad joke
um let me look at the uh that's not the right one that's the final um open recent
open m106 let's see register
caliber caliber light and we'll just pick one
and and of course you can't see it here okay i say something no that's just a
satellite but there is no i saw a galaxy yeah but there's a whole
splash of garbage that i just had to crop it out i see
well nothing wrong in that no it's odd that it's
now when i want to show it you can't find it um i could i bet it's in here
uh
that's okay it doesn't matter it's like when i'm doing a sales demo somewhere you know
yeah and you set up the equipment and it doesn't work nope exactly oh man and then the client walks
out and it works perfectly m106 here we go
let's see if this will load up real quick and my computer is not that slow so it
should be okay so master light no filter is that it yeah here it is so if you
take a look right here yeah like an arc yeah a total arc going
all the way over to the end and i tried with dbe and a couple other things to get it out and it was such a nice frame
i got this little galaxy up here i got a little galaxy i got all these galaxies here and i had
to crop it right right here to get rid of this i could i did
everything i could do to get rid of that even like i tried an axial gradient remover and everything it was just it
was just a big pain in the you know what i even i even i even broke down
and um i i called my buddy ron breacher from masters of picks insight and i said ron
i need you for an hour i'll i'll pay you i don't care and uh even we could that's the best we could
get it it was that bad it was that bright but um but yeah so i was able to take some pictures and uh looks like i'm back on
i'm back on the horse again so i'm really psyched so well thanks those are pretty good thanks
for sharing man thanks adrian it's even better is uh all from new york city it's uh it's
gonna amaze folks because the lights in manhattan are pretty bright i'm sure
from where you're at yeah so um so in long island or are you in manhattan
no i'm on long island but you know in the west when you when you're looking
in the west oh it's you literally have a 40 to 45 degree light dome
yeah from from literally like the the south west to the northwest that goes all the way
over so so if you want to shoot in the west at all from where i go you need to be
above 50 degrees and yeah that's it you know but it's it's pretty bad but that that
uh you think that that arc was coming from glare the moon or something is that well that's the only thing that i that's
the only thing i can really think of i don't know where it came from it's in every single sub it's not one sub
um you know when we were this was taken in cherry springs bortle to sky okay so
dark skies yeah the only thing that was there because for whatever reason
cherry springs star party was during the first quarter moon
okay it wasn't during a new moon so i was taking some data during you know because the new moon was memorial
day they didn't want to do it on memorial day and um so they did it the week after and
unfortunately uh you know i i that's unless if i got some random light scatter from somewhere yeah um i i
honestly can't peg it down to anything because it was pretty dark with the exception of the moonlight
the only thing i can suggest in situations like that is um you know flocking the inside of your
tube you can buy flocking paper or material
putting in additional baffles into the tube as well can help and a nice long
dew shield you know so uh that can also help you know and this was with my esprit 80
um and a uh well the esprit 80 and the uh what was it the um
my uh qhy 268. so um you know that that's you know it was
i never had this issue before in yeah even imaging in new york could have had this problem well
another thing that can also happen too we discovered this when we were building uh ccd cameras that meet instruments was
that you know we always just black anodized parts okay
you didn't flat black paint everything okay black anodized okay
well black anodized is really really shiny in the ir
really shiny okay so it's so it it does help to go in to the
adapters and couplers and stuff like that take some flat black paint go in there fog it or paint it you know with a
paint brush and just get all those little shiny surfaces out uh because stuff like that
will drive you crazy yeah i mean i'm not saying you're crazy damn no i'm not trucking right now
but uh you know i i i just did that um that uh um m27 that you just saw
same scope yeah no problem no problem so you know it could have been just like some little
you know bright star from the field or something like that doing that to you so yeah somebody actually mentioned that it
could be um a bright and there is a bright star right to the right of m106
um that that could be it uh but i i don't know it could have been it could have
been et for all i know yeah i don't know these are the little things you chase as an astrophotographer so nah you know
what i'm not chasing it i'll just crop it out i don't care i'm not chasing anything
i don't have time to chase anything yeah that's right but that's all i got so deep down come
on and hang out with us tomorrow that's a lot that's a lot thank you so much man and uh you know good luck to the person
to uh win that uh that new asi so that's going to be awesome eagle jesse
eagle sorry sorry sorry that's right you just answered adrian
all right good luck man yep i'm in there i also dropped some photos for the uh
contest i don't know if i'm good for uh this month but i just downloaded them tonight
so they'll be up going up tomorrow so all right well i threw some i threw some
in for whenever maybe next month if you don't get these
i throw up new ones every week and take down the old ones so it's pictures of the week and then all the pictures of the week and voted for pictures in a
month so all right all right great all right good night everybody we're going from
the east coast all the way from long island all the way around the world to nepal okay
and uh deepti gatam is joining us uh for the 99th global star party thank you
dpt for coming on hello oh very nice moon shot did you do that
photo yes wow that's awesome beautiful this is the uh
i thought through the mobile phone and this is my favorite picture
i kept it up to now beautiful perfect
so today uh junior squad it's been all i think you know more years according to oklahoma star
party and uh hundreds of global parties on next week
next week and i really i remember i was doing the first global staff party in
20th october okay and the day has gone so fast and we
are already in the 100 closest party and congratulations for that
and best wishes for upcoming days and we'll be joining global star party um
more and thanks uh for this opportunity and it's really feel good to connect
with the all likely minded peoples where i'm getting a knowledge and listening to you all
um so uh today uh my topic of the presentation is
i think about let's talk about expanding universe so let's begin i like for thousands of
years astronomer restless with the basic question about the size and age of the universe does the universe go on forever
or does it have any is of some way has it always its steps or did it come to
being some time in the past in 1929 edwin hobbles an astronomer at
celtic made a critical discovery that soon leaked scientific answer for this question he discovered that the universe
is expanding the universe was a born with the big bang is an unimaginably hard tense point
when the universe was just 10 to the power minus 34 of a second are so wall that is a hundred of billionth of a
trillionth of a trillionth of a second in ego is it experienced an incredible blast of expansion on its inflation in
which space itself expanded faster than the speed of the light
during this period uh the universe doubled in size at least 90 times
going from sub-atomic size to golf ball size uh almost intensely
the ancient greek recognized that it was difficult to imagine what an infinite
universe might look like and so on uh
what the infinite uh universe look like in the greek two problems with the
universe represented a paradox the universe had to be either finite or infinite or
end both alternatives presented problems after the rise of moral astronomy
another paradox began to puzzle astronomers in the early 1800s german
astronomer henries alvarez argued the universe must be finite if the universe
with infinite and contained star throughout albert state uh then if you
uh if you look in any particular directions your line of sight will eventually fall on the surface of the
star although the apparent size of a star in the sky becomes smaller as the distance
to the star increase the brightness of the smaller surface remain accustomed
therefore if the universe were infinite the whole surface of the night sky should be a brightest star it is the
seal of all birds and obviously there are dark sky dark areas in the sky so the universe must be finite but indeed
when many of us were at the school or when we were small we were told that the
universe was expanding but that eventually the gravity of all matter in the universe would cause the expansion
to slow down and reverse leading to the end of the universe scenario known as the peak trance
nowadays uh we know the expansion of the universe isn't slowing down it's speeding up we call the unknown force
behind the acceleration is dark energy and when cosmologists uh say
the universe is expanding they mean something very specific they're saying that the separation
between the galaxies the basic building block of the universe is growing systematically with the tiles and the
big bang equations continuous skill factors which is if it is double in size
double the separation between the galaxies if uh therefore possible for the distance between the galaxies to grow
whether or not the universe is finite or important in in the case of infinite universe just
imagine the galaxies as raising in a sleazy rising kick the mother of all gates
one that extend forward in every direction and how fast universe expanding this is the uh biggest
question which everyone have the rate of expansion of the universe is expressed by a quantity called the hovel constant
and there is always most argument over its precise values and it
is figured that it's continuously updated by a new dishes but however's constraint is about 70 kilometers per
second per megapixel one megapixel just over three million light years you know
that and what is what this mean is that the galaxy that is three million light years further away the anode is residing
73 kilometer per second faster than the expansion of the universe and the
expansion rate is calculated as the ratio of two quantities the velocity of recession of celestial absence and
distance to the object the later being quite difficult to determine how we were calculating how big the universe what
was at any time in the past is even more probiotic this is because at different
time its expansion has been driven by different things like inflation we know that and the radiation pressure of
photons the gravity of matters trying to slow the expanse expansion down
and the repulsive force of mysterious dark universes and the universe may actually be fine infinite in extents but
we can only see the portion from which slide has had time to
reach us in the 14.8 billion years since the bank and we believe that universe is
expanding and that's my presentation thank you
it's good to see you and today i don't have any frames but for that yeah that sounds okay i've been
following your um growth on uh facebook and it's always been it's just interesting to see
you grow before our eyes um on global star party and just seeing you go
through life through the posts online and um you know even with the hairstyle
change and uh presentation was very crisp and um just shows that you
you know your knowledge of astronomy is growing along with um yourself
and um we're we always look forward to hearing your perspective of it and um we
hope to see you on some more star parties in the future and i'm clearing out my schedule so that i
can be at the 100th though hopefully we'll we'll see all of you there
so it is always a treat to watch your presentation and yes that
is uh that is a beautiful moon shot right there behind you yes
right thank you it might not beat the one that i stole from a billion dollar telescope behind me but
still multi-billion dollar telescope motivation i will be taking picture like
you have captured i'm still for that yeah this well this photo probably beats
anything i will take but just like yours and like scott was saying all the photos that we take
whether they're multi-billion dollar um mirrors or a simple camera they're
ours and whether or not they get likes on social media more importantly it's our
way of um learning about the universe and uh studying it for ourselves and you know
bringing a little bit of it home with us which yeah makes it very it's actually a cloud
decision in nepal and night sky is not clear here and i capture uh before five days ago
and this guy is a cloudy and uh it's rainy season here so
it can be difficult for a nice sky observation this day it can be tough i
i deal with it by noticing that at two in the morning maybe it clears up
and there are times i've jumped in the truck at two in the morning just so that i can see the sky because
the clouds finally push through it so so yeah it can be it can be tough to
um deal with and to try and find when the night sky clears up but
you know it hopefully hopefully it'll be clear again soon um dark of the moon it's full moon
now so dark side of the moon or i should say dark of the moon as we call it when
when it starts to uh wane um so that's coming so the night's
uh darkness will be a little bit longer and um
hopefully there will be some opportunities out there i don't know it's just uh okay i don't know it's just a scenario or a ride but
when i take the telescope out the moon is covered by the cloud you know
that this scope inside this guy's here that's that always happens
whenever i pack up there is a mathematical equation for that you know dt so uh and the more expensive your
equipment and the more you want that equipment yes the worse the weather's going to get okay so
yeah that's why we all we think the entire globe is going to be covered in
clouds for the next couple of days now that uh we've seen these beautiful images like this right here so
yeah just just be prepared for it it is this is the way that it happens but uh
yeah but no it it clears up eventually and when it does hopefully we'll be able
to get out and sometimes just seeing a star and trying to name it even though i have no context
for where it is that sometimes just becomes the challenge so you take what you can get
sometimes that's right that's right before we transition to connell who's up
next um i do want to i do want to uh make um a little announcement uh
uh dt's camera turned off here but um but uh uh dt is looking for an
internship uh here in the united states so uh anyone that might be catching this
video uh you know certainly i'm casting a wide net uh but i really do want to
um help out dp dt uh in her uh you know in her search for an
internship uh uh in an observatory at a science center
uh any place where she can apply her knowledge and skills uh she's actually
you know very very knowledgeable very serious and i think that you would find her to be a
great candidate so but um uh dt thank you so much for coming on to
global star party hope to see you uh next tuesday so yeah i will be attending next uh global
survival question great thanks so much okay so um
up next is connell richards connell is uh your program is uh local library
outreach now uh there is something called a telescope lending
uh library uh where people where some of the libraries do lend out you know i think you can check
out a telescope with a library card but uh you're doing outreach events at libraries is that correct
yes that's correct um and a little bit of both actually you mentioned that library telescope program
um it's very probable we'll be a member of that in the future i'm thinking of the the astronomical leagues
one in particular but we have a program like that right now with binoculars and i'll i'll go into a little more detail
with that a little bit um but anyway i guess i should begin here um when i first spoke on on your program on
global star party and uh similarly the astronomical leagues live i was sharing my experiences with
outreach with high school students i was the founder and president of a high school astronomy club
and we were a junior society of the astronomical league eventually i extended some of that to the community
i was working with the library a little bit but this summer i've been working on a pretty exciting project this for ages
7 to 11 and tonight i'd like to share that with you and go into a little more detail on how you can work with a local library
and some good options for programming with that age range
i'll start by sharing my screen here just give me a minute to set this up get my slides here
that should be presenting correctly does that look good deal yeah it looks great all right
well about i want to say a month or six weeks ago i was made aware that there was some funding available from the pa
department of community and economic development and they have what they designate as
educational improvement organizations or eio and these organizations they they
allocate funding to for various educational programs they might be school districts they might be libraries
they might be educational clubs maybe even something like an astronomy club and my local library the abington
community library was among these organizations and i approached them
asking about the opportunity of of doing an astronomy program there over the summer
for kids and you can see on the right picture here this was an image from
a previous program i did this was the summer of 2021
is that forwarding here give me a second here we go
so i've done a similar program last summer at the library was having uh this
summer event they had an ice cream truck there and they had some various groups from around the area
uh just try to come together and it was sort of like a festival as you might describe it and they had these different
stations and it was very friendly to to young people to kids 7 to 11 about that age range
elementary school middle school kids and i was one of those participants i had my own little booth i
suppose you could call it and i had a collection of handouts that i was able to share with a lot of the children
coming through and included you can see on top of the stack here there is what's called a dark sky wheel it's a really nice educational
tool from nasa's night sky network and they have one of scorpius and one of
orion and essentially what you do as you can see here is that you have
i want to say it's six or seven different um cutouts of the constellation in this
case scorpius along the wheel and there are these different images these illustrations that show what that
constellation would look like in various light polluted levels so as you turn the wheel maybe you only see
antares and a couple of the bright stars uh in the in the scorpions pincers up here but as you turn it you see more of
the stars come out here it talks about ptolemy's cluster m7 i believe that is
and it helps kids really understand the effects of light pollution in a very simple way it shows you well if you're
standing in say the middle of times square this is what scorpius looks like and if you're at a nice dark location
like cherry springs well this is what that same constellation would look like and then on that wheel there are some
recommendations about sky friendly lighting dark sky friendly lighting and how to understand light pollution and
and really make the most of your outdoor lighting without polluting our night sky so it's a really good tool to get out and
families see this as well uh light pollution is of course a very important
subject in our outreach that we do as amateur astronomers and you'll also notice here right under there is a
little cardboard planisphere so there's kind of a cardboard uh cutout and there are these edges that
fold in and inside those folds there's a wheel that you turn that that forms the planosphere and these are from the royal
astronomical society of canada we bought those in in bulk off the website and those are really easy to use a nice
take away planosphere for something small like this and i also had a moon map a meteor shower guide
that talked about radiance and that kind of thing and then there was a sky chart from nasa which showed the
entire sky for that month i believe it was august showed you where some of the bright constellations were and also
it had an illustration of the ecliptic that i thought was really interesting instead of one line it actually had two
dotted lines that were parallel and it showed that you know with the various inclinations
and various different orbits of bodies in our solar system they can fall a little bit above or a little bit below
the ecliptic and that helps new observers and kids uh know where to look for the planets in the night sky
but with this start to library outreach i found this really to be a simple and easy program to put together i had a
couple of planispheres and moon maps laid out a little bit larger ones that i use for my observing and people were
really interested so when i found out that this grant funding was available i came back to them uh this summer
and i was able to put together a larger program called a tourist's guide to the stars
and this would be a four session program we would focus on the moon the solar system constellations in the night sky
that was a that will be this week and it's much more observing based what we like to do and i'm very excited for that
one and then a fourth and final program on cosmology and galaxies and exoplanets
so we started this a couple of weeks ago and it went really well we were trying to figure out what
kind of resources we would have available there and how the program would be structured so i decided when i
was writing the proposal that we'd do about a 20-minute talk for kids that age that would be
what i thought would be the the best i could manage with you know their attention spans they're always
distracted they're trying to find new things to do they want things that are very hands-on but i would later find out that they were deeply interested in this
and they they wanted a little bit longer talk so in the two remaining programs i have i think i'll extend that a little
bit after that of course i had an activity i figured kids would want something very hands-on and at that age that's the best
way to learn so for example with the moon i had an exercise with the faces of the moon that
you'll see in a little bit with the solar system i had some stress balls just
they were i want to say there were 10 of them the sun moon and planets and they were all these printed colored nice
little foam balls that we were able to stick on to this poster with electrical tape and learn to put the planets in
order you'll see that in a little bit so with those two things the talk and the activity combined i thought i had
things set and that was a turned out to be a really good formula for teaching kids this age and of course you want
them to take something home something to remember something to learn from so i had a couple of handouts uh that i
collected from around the internet various sources that i knew and trusted well
in fact this week you saw that night sky light pollution wheel earlier that's
going to be a handout again this summer i had a handout on the craters of the moon earlier in the first program about
the moon but then there was something really exciting that we were able to do and i'll show you that in a little more
detail soon uh we were able to give books to the kids it was the stars by h.a ray
which is a really nice introductory book for learning about astronomy at that age
and here we have two posters i made from the first uh two programs that we did on the left is a
poster of the phases of the moon and it looks a little unconventional with sometimes how you see this type of chart
represented so you have the sun shining on the earth and there's of course the new moon here and normally you might see
a bunch of half-lit moons as of course the moon is always lit but i wanted to show what the phases look like relative
to where the moon and sun are in our sky relative to the earth and after presenting this a lot of the
kids were wondering well where does that dark part of the moon go why do we always see the same side of the moon and
to explain that i took uh the moon over here this little phone moon foam moon and a flashlight and i turned
out the lights i put the flashlight here next to the sun and i put the moon where you see the new moon uh cut out there
and i pretended that the moon was orbiting around the earth i swirled that ball around and they were able to see
that no matter what no matter where the moon is positioned it's always half lit and so that was kind of i suppose like a
eureka moment for the audience they they always know that they see the moon as different phases so i was able to
compare what it looks like to what it actually is is physically represented as in terms of how it's lit
and that was a really nice activity i thought to help kids understand the faces of the moon and then you see on the right here
i had this other poster and if these foam stress balls were removed you'd just see this uh sort of branch
structure with a bunch of circles i drew in and i i had this bag of planets and i
was able to say all right we know what's at the center of the solar system we have the sun here now what's the first planet from the sun and they might say
the moon they might say earth and it was kind of fun to see what they knew and teach them a little bit more about
how our solar system is structured and they really enjoyed that quite a lot so as i stuck each planet on here mercury
venus earth i was able to share some information through a slideshow talk about what the hottest planet in the
solar system is the largest which has the most moons and they found that really intriguing that really captured
their attention well and i enjoyed doing that quite a lot now back to this book i was talking
about earlier this is the stars by aj ray he was the same author of the curious george books that many of us
have read and of course he's an illustrator as well and you can see on the right here this is one of the the pages from the
book it's a really well illustrated uh version of how to observe the night sky
and the first couple sections of the book talk about all the constellations it introduces them it talks about what
the ecliptic is how your latitude factors into what parts of the night sky you see
and then it goes through these seasonal sky charts and then at the end of the book it talks a little bit more in detail about eclipses and occultations
and some other things like that and how our night sky is is
geometrically spaced relative to where we are on the earth you could look at it as almost a mirror of of our latitude
and longitude and i think this is one of the best books that you could use for introducing kids to astronomy of course the
illustrations really help it's written for that age range and they're from my research there weren't many
comparable uh books out there for introducing this to people and i had read and heard from a lot of
people this book was first published in the mid 50s right before the space age was getting started and so many people had
said i read this book i remember this is what got me started when amateur astronomy was starting to come of age in
the 60s and 70s and knowing that this started off so many of the uh
well-respected amateur astronomers today i figured this would be a great choice for a book and fortunately we had the
resources to be able to hand out these books to uh all of the kids in attendance
now as of my second program we only have two of the books in this stack left i'm
very happy to say that and as i gave the books out they were all looking through it they had a lot of questions and i think it'll answer a lot
of those questions for them and help them get out observing you know in the backyard or at a local park or something
i really think it's great to get kids hands-on with astronomy instead of just reading about it or seeing it as
something intangible that's that's important for every age range in fact
i agree now with that said uh we have two programs left i have the observing program this week
that will be on thursday and the week after that will be the cosmology one and i'm really excited to to see how much uh
how much information i can i can fit into there and what they think of it and all that
and after that after that program concludes a tourist guide to the stars my local library is
hosting a star party so a couple of months ago this was a long time ago
they bought a five inch newtonian reflector on an equatorial mount
and it took forever to get here with all the supply chain issues and with all the things going on um
who knew where it was just just probably sitting on a ship but eventually it got to us and unfortunately it is ready to go for
a star party or something like that i was able to check it out a couple of weeks ago collimate the mirrors and
align the finder scope and all that and like an equatorial amount seemed a little unconventional for an astronomy
program but i figured it would be great for tracking if you have a long line of people and we're going to set that up that
telescope up early in august uh i have the date currently set for august 3rd we'll be
hopefully looking at the moon the first quarter moon or waxing crescent i think it is from the parking lot and we have a
couple of rain dates set for after that and that i'm really excited for because we finally have a telescope to do
hands-on outreach with uh they're not just looking at something in a classroom or
on the internet or in a book as valuable as those things are they're really able to see the moon for themselves and i
can't wait to see you know the look on everyone's faces they see the moon's craters in a telescope for the first time
however though we do have that telescope the library started a program recently where they had these backpacks in the
young adult section and there were all these different topics included one of them is ghost hunting there's an astronomy one there's
outdoors there's cooking and you get a backpack and there are a number of items in there and you can check it out with
your library card just like any other item there and basically learn to do some kind of skill or trade or craft or
hobby or something like that now in the instance of the astronomy backpacks that they had they had four of
these with celestron seven by fifty cometron binoculars and a book on 100
things to observe in the night sky and they said they still had grant funding available the state was
very generous with what they were able to help us out with so they asked my opinion on what we
should add to those backpacks to kind of round them out a little bit more and you can see the list on the left
here are some of the things that i suggested they add uh there was a guide to the stars planosphere an 11 inch
version uh orion's moon map 260. that's a nice simple paper map with 260
craters and impact basins and ray systems and all that kind of thing on the moon of course there's also a red flashlight
in there for reading those at night and using with the binoculars and two books which i felt uh were instrumental in
getting me involved in in amateur astronomy and observing which were of course night watch by terence dickinson
and turned left at orion by guy casa lemano and that last book turn left at orion if
you've never read it before or if you've never seen it it's a book on deep sky objects and i think it has 50 or 60 of
them and say you have a page or an entry on the swan nebula it'll have a sketch as
to what the swan nebula looks like in a four or five inch telescope uh to what a new observer is doing the
author actually had this artist go out and he gave him a telescope and said look at all these different things and basically
make a sketch of what you see so it gives a really great representation of of what you can expect when you're being
introduced to astronomy uh compared to the famous hubble pictures and i'm sure famous web pictures will soon be added
to that list but anyway that's a really great book for for setting an example of what you can see through a telescope
now i'm currently working on doing this with another local library the dalton library
the acl abington community library is able to help set up programs within our
school district and that applies to to this library dalton as well and i'm currently working on a number of dates
for running the same program there a tourist guide to the stars and it should be very exciting to reach another
audience in another part of our community and expand this project a little bit and then last uh but certainly not least
and you talked about this earlier scott there are a number of programs out there where you can
essentially a library can acquire a telescope and you can check this out just like the backpacks are just like a
book from the library and the league has one of these the most popular
library telescope program out there i think it was the new hampshire astronomical society that started to set
this up they take a tabletop orion uh four and a half inch uh telescope it's this little
thing maybe about this big you know if you can see on the camera um and they make some modifications they
put a zoom eyepiece in there and and secure that with a screw so it doesn't fall out or get lost there are warnings
on the side about looking at the sun with telescopes and binoculars and how you shouldn't do that without the proper
filtration and expertise there and it's it's a really they take a very
user-friendly and introductory telescope and make it even easier to use with a zoom eyepiece and a couple of mechanical
modifications and guides there's even a cover put on the back so the mirrors don't get twisted or knocked
out of collimation and then these are awarded to various libraries so the astronomical league has
10 different regions and they award a library telescope to each of those regions and then they also
have an 11th telescope that they award to their members at large which would include myself
now i was reading in their reflector magazine the other day in the last pool of applications it
which i think that was for 2021 or 2022 there were some regions which had no
applications at all so i would encourage the the astronomical league members out there if they do know of a local library
that would benefit from a program like this and they're in one of the various different regions it's certainly
something to apply for and i know i'll be applying myself i'll fill out that application
soon and that'll hopefully be in the next pool and secure another telescope for our
library that can be checked out and so with all that said
i've been trying to expand my own outreach efforts first i focused on high school students like myself and college
kids as well and now it's nice to work with younger audiences and parents as well and see how it works with families
and kind of broaden my knowledge of how i can best reach people in terms of astronomy
and i would encourage many other people out there to research their local libraries their local astronomy clubs
perhaps a group like the astronomical league or the royal astronomical society of canada there are a number of
wonderful grants and resources and clubs out there willing to put in this work and it's certainly worth doing uh
because i'm sure as amateur astronomers i'd assume would agree uh local libraries are a truly great resource for
learning and expanding your skills so it's certainly worth getting out there and and trying to help others and
expanding our hobby so i i really appreciate you having me tonight and helping me to share this this
opportunity of reaching younger audiences and libraries and i certainly hope to see more people doing this in
the future so thank you very much thank you very much connell i i hope that uh you know the whole community can wrap
around uh your program and and uh you know give it even more strength as you continue on um you know
i know that you have uh an incredible energy and passion for this and i think it probably helps fuel you for the
for the next thing that you do but uh it does help to have others uh join in
so thanks for all you do connor thank you very much i appreciate the help yeah
okay all right so um up next is going to be adrian bradley um
he is uh tonight he's going to be taking bob fugate's place uh bob had a family
issue he had to deal with and so uh adrian thanks for coming on uh
all right well since i'm taking over bob fugate's place
i can thank him for the level of detail that i began to get
in the milky way shots including the ones that you may have heard i
snagged an award for the um light pollution um
category for the royal astronomical society of canada there weren't many entries but it was
still a good thing to have work recognized and even more important the runner-up image
for having a detailed the most detailed milky way of the bunches of entries that were in
um that made me feel good and let me know that the process
started by listening to some of the presentations bob fugate's done on here and his work
really understanding your camera and what its limits are if you want to go for a higher iso
just have to be prepared to deal with some of the luminance noise that you might have especially if you're shooting
a dslr some dslrs are a little better than others for
doing night photography just because their signal-to-noise ratio is very high at those higher numbers
um some sony cameras come to mind and the canon 6d that i use that's modified
comes to mind as well so i will go ahead and share my screen
and share some of the images that i've gotten recently which includes this this isn't a
nighttime image and i'm sure you're going well what gives why are you showing this
well when preparing for a shot it's sometimes important to go to the
site that you're at that you're going to shoot get an idea of how you want to shoot it
um so you so this is a daytime image especially when you're at night and you
want to come to the same place and you want to shoot at night you want to be prepared to um
know where if you're on terrain like this you wanna have an idea of where you're
gonna sit where you're gonna look and where you're gonna shoot from so
this is facing south and here's why that was important
because as you can see same perspective
maybe slightly different um but same perspective there's my shot and there
was the light pollution winner um for
the uh contest for the rest contest i submitted this there's different colors
here just sort of there's some fog over here as well just representing
different ways that light pollution can affect the sky and you have a faint
milky way here now you can see that this is purple
it's a purplish um sky but
you never stop working on images seeing what you can do with your image
and as far as detail goes the level of detail in the image
can also be important depending on what you're wanting to do especially if you use a lot of noise reduction like i did
here one of the neat things that adobe products lightroom photoshop
they've come out with a way to select the sky and the and then you can inverse the sky to
select the ground so now a single shot can be edited
as if it were a composite shot
so let's see here's here's an example of that on the beach where
i edited the sky separately from the beach even though this was
a this was a single shot and ended up with this image
and so it's it is possible to if you're not good or don't like
composites single shots where you won't get any of the uh
you know you won't get any halos from not quite matching up the uh
landscape you know some of the some of the things that you'll see when it's a composite
shot um you don't get that you you get a straight image and you can edit the
basically the two sides of your image separately your milky way shot and
your beat shot now unfortunately that requires that you be somewhere that's
dark enough to get enough photons for from your milky way
in in order to do that so learning composites is still a good idea
and so i'm gonna start closing down and going through some of these shots here's another
version of that and i like seeing things like this there was
a windmill farm in the distance and you can almost see the poles of the windmill farm here
that that's off in the distance so and then this log right here you know
whatever this is details can really make an image um
stand out and um you know just if you choose to leave a lot of colors in
you know that's that's also a choice there this bright white light was there
obscuring the core here but you know that i chose to bring all the colors out that particular version
of the beach image so this image of course i did not take it
but you saw it in the in my background i was going to start off with this and
give my nod to the wonderful day that we had with james
webb an interesting thing about this is
perspective this is closer this galaxy being closer to us but
similar in brightness from our perspective to these other galaxies
um it just gives you perspective it gives you some perspective that uh
oh yeah everything yeah everything that we're seeing here um
you learn something new and this is a low resolution image and i'm still looking at all those galaxies
yeah on my own computer so right you know that imagine the original image
you know that after it almost blowing image on your screen and then
taking a a loop you know like a little magnifier that you put up right up against the screen to see
how many small galaxies you can actually find right
actually here galaxy yeah these are all actual these are all every little dot is a galaxy here they're in another galaxy
yep that's that's an amazing thing so when we look at our own galaxy
um if prior to that those of us who you're on the ground and
you like doing wide angle and you still can see another galaxy or two
there's m33 right there yeah so
you know i guess a you've got our own you've got light from our own galaxy here and a lot of haze
and then using kind of the light that's behind me um
and you still and there's even at our level where we're looking through a 16 mm
16 millimeter lens on a camera the universe is still big enough to show
us light from these different areas it's amazing what you
can catch on your camera um here's a double cluster and here's the heart and soul these are favorite
targets of um astrophotographers sometimes they'll focus on one or the
other or both and there are a lot of other objects in here that i haven't even
looked up this little nebulosity here so sometimes when taking an image i like
to take it for the sake of if i get detailed enough
that you know it shows me a lot without you know i may not have been
able to see it or i may not have a telescope but i can go back into an image and just sort of study it to
see what's there right and then you have capella here um
and the pleiades which lets you know one thing the winter circle is coming back
um even when it's uh even when it's summer sometimes reminders in the sky let you know that it's going to be it's
going to be winter in our part of the the northern hemisphere and it's going to be warm again in the south
so this was the runner-up image yeah and
again this is where crediting bob fugate um
comes to mind because this image was picked as the
best detail of milky way in an image i have a fairly simple
this is a fairly simple composite of a park that we were doing this image a dark sky preserve and there's some
there's even somebody in here going back and forth observing had their red flashlight on
um you know you see landscape photos with beautiful foregrounds
and you know where it mountains the winter was a mount a mountainous region with the milky way over it which
um i don't blame them for picking that one first but what they and it surprised me
because i threw this image in because i personally liked the detail i was seeing
and i did not know that this would that they would also like to detail so
milky way shooters when you can come in at a this is a
portal somewhere between a portal 4 and a portal 5 site and i have the some parts of the lobster
claw here and the cat's paw and the prawn nebula down here
there's ptolemy's cluster there's the butterfly m22 is right here there's the lagoon
there's the triffid you can look you can even see barely see dust lanes in the trifit the
uh blue over here looks like it didn't quite make it but dust lanes on the trifid and
then you go up here this is an ngc object i forget the name the sagittarius star clouds here
you can see the shape in m17 remember they call it the swan and the omega
nebula and you can barely pick out the shape of a swan here
here the eagle nebula as it gets near the edge of the image doesn't quite turn out as well you see
barely see any dust lane here at all we know that in the middle of this is where the dust lanes where the
pillars of creation are a little too small with a 35 millimeter
lens but but going in here seeing nice round stars and seeing focus
makes a huge difference in the appearance of the milky way this was a two minute
exposure untracked and even in all the haze that you're
seeing here we're picking up milky way detail a lot of it has to do with how sharp your how
good and sharp your lenses are how sharp you can make them and
if you can track the longer you track the more detail
you pull out and this was with a canon 6d um
there will be some shots later we'll go go through some of these where
i started taking pictures the milky way by the road and in a spot that was a little darker
here you have another picture by the road
things i like to look for in milky way detail now we just saw in
one image you know parts of the core so these
may not have been as sharp as i could get it but they were still pretty good there's barnard
yeah which you can see next to tarzad and altair if you can see that and you can see
the coat hanger you've got pretty good detail on a milky way shot there's the
yeah yep so so there you have it there was an oncoming car behind me which is what lit
up the sky like that or the ground this was
a you know another image the code hanger i kind of cut the coat hanger off there but
you can still see barnard z which
i consider that a neat little trick if you're not sure your milky way is very
detailed zoom in and see if you can see this nebula and if you can see does
it look does it look like an e or does it actually show
it's uh that it you know two parts here it's a little blurred
but if you you know if you can find it there's a good chance you got good
detail in your milky way shot and even in the shot with the oncoming
car which is why the trees are lit the way that they are i would love this
these trees without a car coming at me but any light when it's dark enough any
light affects how um how your shots are going to turn out and this is the danger of trying to
image in the middle of the road you have to get out of the obviously i got
out of the road and i got my equipment out of the road too yeah turning north
i shot north because i said why not and it turns out there was aurora
happening that i could not see to the north and then beautiful part of the milky way
so aurora borealis does happen if you're far enough north these are fireflies by
the way this from taking an image that's the truck i drive in um
you can see spectacular yep this is um this is just the middle
of the road in the middle of a dark area in the upper peninsula of michigan
sometimes the most uncommon and in some cases just flat out not so safe locations but
they can produce beautiful images so sometimes you take a chance if you want
to get a unique image kids don't try this at home yeah
don't try it at home all right so this looks familiar however
this is with the ace the sony camera a7r4
um let's zoom in that cloud down there looks like a storm cloud and then the
milky way kind of like you know just crashing into it it's just yeah
like and then you can see kind of like waves you know of uh
of the atmosphere it looks like it's kind of curling around it's really spectacular yeah a
lot of drama there which is why i shoot with clouds i know there are a lot of
folk i've seen posts online where people are apologizing because there were clouds
and how many more decide not to shoot because there's clouds
i wanted the galactic center i didn't get it at first and you saw a few shots that i took where
the galactic center was covered up to about here here the galactic center starting to show itself
um so i took a few more shots and if we scroll
the precision on barnard's e turned out
even better than with my other cannon only problem if we go look at the
coat hanger the stars are a little oblong so my tracking wasn't as spot on
but the focus was good and the detail was good enough
that you still if you pull out you still have
a lot of good data now it doesn't show up quite as much you know the uh color here
doesn't show up as well but it's still there so there's a trifid
it's this reddish color and the dust lanes don't show up as clean because you're using a because i
was using a stock camera but the shape of the omega nebula shows up
you know shapes here this is it encourages me to do a little more
imaging with this camera because if i can if tracking works out
you know the detail here i think is pretty amazing and i also
know that i have a true color this greenish glow is sky glow
i'm in a zone where sky glow begins which
some portal 3 sky sky gloak or air glow can begin
in a portal 3 site but i guess it has to be a pristine bortle three not a
you know not something that is bortle2 turned into portal 3
because of light um hey either way you know light pollution
or like domes which there there still is you can kind of see a light dome here um just by
the fact that this doesn't keep going through you can see some stars but the color change underneath these distant
clouds it's like the clouds are kind of catching what light pollution exists down here to
the south of where i'm at and you can see the color change here so
you know that st ignis in michigan is over here and the underside of the cloud shows
light from that city so if this were a completely dark sight
everything would be this under this grayish tone or even black which
look at the color this was the aurora is taken with the a7 r4 there's a big dipper my
original reason for firing at firing to the north was
i may as well get a shot with a big dipper in it and i got so much more than that
now i might be able to exp to show
and it would be this where my hand is that's actually m51
it's been because of the way that this has been processed it's blurry but that is actually m51 so
you can pick up a galaxy so many
you know billions of miles away and yet
see it in you know in a uh in a fairly simple image
as long as you've got in a good focus you know a lot of this information here
is just stars so so that that's always amazing when doing
images we'll quickly go through a few more these are very these are fairly new i think i shot these a few days ago
again attempting to use techniques that i'd learned
um to try and get some precision
there's a trifit again now you can see the colors of the triffid you can see that the stars are
some of them are not quite so round so you just have to
depending on what you're going for and when it's windy the trees will the tree will blur out as
well so this was an attempted composite here
a couple meteors and shooting other parts of the milky way is something that i always attempt to do
um just because it's you you begin to
your pictures begin to become predictable i think using the you know using the galactic
core um you know putting it in front of whatever foreground
i like to simply take people to where i am and show them that this is this is what it looked like
and this is what it looked like when i decided to point in another direction so you've got a couple meteors that
showed up this is jupiter mars and the pleiades this is our new
planetary lineup and i don't know if i've put one of my panoramas in here but
we'll we'll see if i did this was an experimentation with uh
light painting there's andromeda over here and
do i think i reduced the noise a bit much yes i did a lot of noise reduction here
but the concept is amazing it looks like it's you know this presence you know
yeah yeah for me for me in my cell phone i saw in 3d
the tree i i see i have uh of the sky it's amazing the
the the the effect that that make this
is amazing really white painting can create this sort of effect and it's something
i'm going to play around with more um because yeah
of the images of the crap of images that i took this one was pretty well liked
so but and it's again it's it's it's uh you take the winter milky way
and so i was on this other road over here when i took the other picture
so the tree was more distant and my light didn't reach it this road is right next to this tree so my light reached it
just fine and i was able to create that look so
that's all in experimenting the other look i love it i i love that
picture of the tree yeah it's amazing i think that this isn't a special thing
between the life of the tree you know the sky is something like a universe
around it absolutely absolutely i love that yeah sorry
yeah no thank you cesar i i appreciate that the moon setting over here
milky way showing up it's been something i've tried to do for a while
is to present the moon in the same in the sky at the same time as the milky way if i wanted
to do it tonight i would have to get up at about three or four in the morning
and try and get the moon which would be somewhere here
and take that photo i believe it's possible but i also know that i have to
go to work in the morning so i will probably not make it out to take that photo
this is a single 20 second untracked image and just sort of shows
how you get this from a single image um processing it because you can process
the sky separately from the ground and in this case i ended up doing that
so there's no composite so there's no even though you got power lines photographers and power lines sometimes
don't match even though you got the light of the moon here but
one of the advantages of single shots is you don't have to worry about when you have things sticking up
like trees you don't have to worry about them not being perfectly aligned
or doing tricks to get rid of you know the horizon and then replacing
it um if you get a good if you get enough
good data then you simply process the
you do masking on the ground and process that you mask the sky and you process it
differently and you end up with a pleasing image you may not in 20 seconds
if you look down here remember the detail that you saw in that other image you don't get that same
amount of detail with only 20 seconds it takes time to get more detail for more light to
come in from space but if you're looking to make
a pretty picture or show people exactly where you were
then you can do that without a tracker just a tripod and
if you're shooting with a wide angle lens of 16 millimeters or more or less i
should say 16 15 14 wider 20 seconds is
a good time in which your stars will remain mostly around you may get
these you see these are kind of football shaped so round stars
at 20 seconds for 14 millimeters if i go down to 18 seconds or
something the stars may still appear around um with my 16 millimeter lens but of
course using a tracker you don't have to worry about here we use the tracker again
and i think we go about 30 seconds and or we may have gone a minute i think
we went one minute and so you can see a little more detail and a few more
stars the more time you can spend the um
you know the more time you can spend the more detail you get out of the sky and if
so this is a composite there's a little bit of a shadow but it didn't turn out bad
i was able to work on the ground as it's processed separately
layer it in and this is a highway that i'm on all the time whenever i go an image
so you get better at composites it can look like a seamless image and this one looks
pretty seamless so i mean there there are some small things here um
i bet you if i scroll in uh it's not bad so so getting better at
composite images either way and then i this may let's see how many i have left i have two okay
so let's so we'll go through this was a two minute image and it was comp it was a composite image
so that the ground i could um you know i could process the ground
and then process the um sky and the level of detail the milky way comes
in from imaging it for two minutes the longer now those that like to
stack the reason they do one removing noise to
um pulling some of the detail out with shorter
um with more shorter exposures and those that can stack two
two-minute exposures you're simply you know you're creating this turns into the level of detail of
an astrophoto and then as long as you combine it
that's where some of the some of the images that have a lot of detail will come in what i found
um slightly decreasing saturation brings the sky closer to how we see it
with our eyes
one site have seen this coming at us and we've seen the shape and the dust
lanes and we even see m8 right here we see all of this coming
at us maybe not to the level of detail but we see this outline we know that
that's what the milky way looks like naked eye and we um
and then we we pull out more detail and then we can
start going in and taking a look at what we're seeing from here
noise when you noise reduce it then you get this overall painterly look
and you know that's how you can finish your image now this is again too low for me to look
for the barnard e um look you can
look at some detail here where if you go far back enough this looks kind of like
the horse i believe this is has an official name of crazy horse nebula
and the more detail you get the more you deconstruct this horse into various dust lanes
as you go in and then you've got this part of the milky way that
almost looks almost looks like a chamber of its heart or something even though we know it's hard is here if you're really good
you can you get the constellation sagittarius to still be very visible
in your shot and along with that m22
so just a few things to look for
yeah and one more quick thing i've learned that lightroom can stitch together
panoramas and even if you've got a 16 millimeter lens with distortion
it actually corrects the distortion so that the sky is
properly sized the distortion ended up on this power these power lines here right and i'm
okay with that it's sure it's like looking from southeast
to [Music] northeast that's a pretty nice field of view
yeah it's such a wide field of view so you're you're normally stopping like here
and then as you're looking what i did this for was the new planetary alignment
here's saturn there's jupiter there's mars there's the pleiades
venus is not hasn't risen yet and that's capella right here
and this is a part of the winter milky way this is andromeda over here
so this is um this was my attempt at the new
uh planetary alignment um with the pleiades in in line with jupiter and saturn
and there that goes and then finally
if it's dark enough in the sky the milky way can still make an appearance even though there's tons of light light
coming from the lighthouse they've lit this area up this is a bustling campground
full of bright yellow light yeah and other i think there's other bright this bright light over here um
i used to image here a lot in the winter everything is dark no one's around it
doesn't feel as safe which lets me know that it's a good place to image
but it felt very safe i felt like
all i have to do is walk over here and see if anyone is up
stargazing there's plenty of people around so of course animals typically
go away when people are around and yet the milky way still shows up because the sky is dark enough
so this was a three panel panorama that i shot i aimed at the milky way i
aimed in the center i aimed towards the lighthouse
each shot had distortion but when i put it together in lightroom
they the distortion was corrected everything is the right
angle here every well everything is there's no distortion so that was a very
pleasant surprise that i found that lightroom could do
that which means i can shoot panoramas using my 16 millimeter lens i don't have
to worry about the distortion anymore i can let lightroom take care of it
so that's that's where that super wide panorama came out where i was doing that but this this is essentially
us looking at my favorite place when it turns into a campground and a
tourist site yeah which is why i left it and i went to that road that
you saw earlier where it was still dark
this place shows up in the light map now because of some of the lighting that goes on here
but the sky is still sky is still dark enough to get a
reasonably uh reasonable looking milky way although you can see it's a little more faded
it's more into the background you can still see it in the sky even with all this light
but you know it isn't going to be as clear as some of the other shots i took
so with and this is what it used what it looks like when it's colder these lights
are off like you're seeing here um there's maybe one or two other lights
in the lighthouse itself there aren't any other lights around here everything is dark
and you can see this was uh this is back in
like april i believe when april of 2021 or something when i was here
no other cars i'm here by myself dark enough sky and
that's when that's when the place really shines as far as uh dark of night goes and as far as using
it to do some astro imaging um so to me this is this is when it's at
its best although it's a great place to camp during the summer but
you know the winter the winter months and then leading in the spring they leave the place darker and
you come out you can see the star as well here so well i've gone on for quite a bit it's
10 37 where you are scott so i'm gonna stop here all right and i'm going to give you back
the uh give you back explore thank you all for
letting me talk about the uh my milky way imaging how it's been
progressing and some of the things i look for to determine if i've taken a good shot or not
that's great that's great so uh yeah i think it's time to call it a
night um but uh we had a great 99th global star party and uh
uh we're ready for the party for the i just got a notification that seth
shostak from he's the he's the uh the official astronomer for the seti
institute and he is going to be on the 100th global star party so that will be really interesting wow
yeah if you've never seen really nice talk he's uh he's very knowledgeable but he's very
funny very entertaining guys and uh you know so i think you have to have a uh sense of humor when when your
job is to find uh uh extraterrestrials so yeah
yeah yes and something that is real that that we found in our surprise in argentina is that
uh professional guys professional astronomers really really are
enjoyed because we invite hymns yeah we buy them and
they they have a lot of fun maybe more than one
than us oh yeah really happy people they're not competing they're not competing with other astronomers yes do
you remember to to eric gonzalez for example that he works from uh he's
really it's it's our our soul of the party today [Laughter]
yes completely completely yes i i i'd agree with you that the professional
astronomers are the best for a photo yeah because they love to to to explain
and enjoy um make more fun to the subparties
yeah yes absolutely well great oh and cesar i meant to ask you how is
the the renovation of the historic uh observatory complex in argentina how is
that coming along uh the the well we are awaiting
the the the government of san miguel that is a small
city the major have the keys for for the observatory
the complete control because we can make we can
start to make improvements but we need you know we need the permissions
some support we don't start to work hardly because we start to
work in some parts of the of the old telescope that actually one of um the gustav telescope are
working now um but well we are
preparing some cameras ccd cameras or something
that the we call it municipio while they go the local government of san miguel
to buy some cameras first
they need to to make improvements in wieldings because the weldings the
constructions are very old and we need to to make improvements to
make the building safe yes safe absolutely absolutely scott this is the
the most important part now i think that first of all that is that
um the government national government is going to change next year
uh in one year one and a half year more
the political color of the san miguel
city you know it's uh maybe the
of the same next president maybe because
instead south america is going to the left we are returning to the right
is something yes we are
yes yes we but we are going we call it right and its center is more liberal of
course um both both parties are uh very democratic
um really but but the the economy now is going to the to the
hell absolutely and this is the problem that in the next
next next year we can make a lot
uh for for re make the improvement in the observatory but
in the wild time in the in the in the same time we are preparing
more equipment and we i i i am totally
um ready to to to
to to helping disguise cleaning optics repairing because it's totally possible
the size refractor is a beautiful piece of optics and
we have already the the septic lenses to clean we clean
actually only to keep safe uh with uh you know about the
department of humidity or oh
yes absolutely i i in my uh official
story in one of our groups about astronomical optics i
put uh i i showed a mirror that i cleaned
next last week with fungus and without and i told to the people please don't
don't store your telescope in in you know in in the
backyards uh with the tools to gardens i'm liking the shad outside
totally humid place it's like maybe mississippi
i don't know but it's really because we are in a story we have a very near to
the driver uh if you live in mendoza in arizona or
you don't have problems but i and many people say okay thank you
because you know sometimes this kind of uh of posts that you
make you post something that explode by the people say oh yes i have the same
problem yeah that's right because i maybe i i clean them maybe i don't know
maybe i clean a 1 000 mirrors
fungus in the mirror in my career but maybe 1 000 is possible because it's
the most thing that they say come on and sometimes is a
don't make the make uh how do you say don't make some uh problems in the in
the coating but many
well for for refractor is is the is deadly it's terrible
yes for for for mirrors maybe do you have some damage but it's not so that's
not so so bad yes but especially on refractors
i mean you have to take the lenses apart you know and then get them yes you need to disassemble it and that's that gets
to be either difficult or it takes a lot of time so if you send somebody like caesar to get it yes
enough
yes absolutely i disassembled the the 127
127 of septic triplet um this is very very nice the the mechanics
very really was for me a beautiful work because
i do you remember maybe scott that customers i don't know why he put the telescope he
forget the telescope outdoor in the in the backyard and
coming a lot of humid between the the glasses and i disassembled it uh
between the the second and the third objective i put out the cell
but it was easy because the quality of mechanics all was completely
soft yes but it's a pleasure i was a pleasure and we made uh
really uh i think that that
worked very very well and actually this customer don't have more problems of
of uh humid inside the lenses that's good yes i i enjoy the make this my work
i'm near to to have 30 years of working in
in optics in astronomy optics yes yes and we are opening maybe in two
weeks in two months a new store an epic store but with the middle of the
store completely full of of uh telescopes
glasses sunglasses in one side and in another side okay so
you need to do you need to let us do a show sometime from your showroom okay so
yes absolutely completely yes middle of opt in the middle of optics
i'm going to get going fellas with this adrian take care man joe thank you great oh no me too yes
happy jwst day yay that's right all right so
thank you thank you thank you so all the audience that's out there watching uh
and for tuning in and sharing and helping us out here uh on the global star party
we as i mentioned we'll be back next tuesday with the 100th global star party
uh with many of your favorite speakers uh including a you know a surprise uh special speaker
with seth shastack who is the principal astronomer for the seti
institute so uh you'll love his uh presentation and i'm really excited to have all of those
people on as well so you guys have a good night uh keep
looking up and we'll see you soon
