Global Star Party 74

Transcript:

6:00 p.m..Scott Roberts - Introduction
here this meeting is being live streamed we have a choice to either do got it or get out of here get out of here doid you
6:05 p.m..David Levy – Intro and Poetry
said yes 74 times in a row are you really gonna say no now
no no David Levy is a huge part of global
6:20 p.m..Astronomical League Door Prizes – Chuck Allen
star party I think no not as big a part as I used to be
6:30 p.m..Karim Jaffer - RASCMC
because I've lost a lot of weight from all the effort of doing
6:35 p.m..Adrian Bradley - Sky Scapes
Global star parties yeah I've lost a lot of weight I think I've lost about 15 pounds wow I need L 15 pounds 15 pounds
less of d right now they they called it the quarantine 15 you know
6:50 p.m..Molly Wakeling - Astronomolly
so uh yeah it it's
7:00 p.m..Mike Weasner
uh but go how come how come the amount of weight we gain or lose what's that
how come the amount of weight we gain or lose always has to rhyme I don't
7:10 p.m..Ten Minute Break
know sorry just popped in my head my apologies without Nathan here tonight I
7:20 p.m..Tyler Bowman - Tyler’s Imaging Journey
figured I have to be the one to come up with witty things on the fly so Nathan will be on tonight oh no I said uh
without without him yeah yeah yeah but he is interested in coming back uh soon he said he's going to start putting
7:30 p.m..Jerry Hubbell - Live from the MSRO
something together right away he was uh he was just so funny Ian he was great
you know so he stayed on the entire evening he like he came in straight after school logged in and then stayed
7:45 p.m..Annie Scarborough - Exploring the Stars with Your Family
with us I think he liked it
so what's not to like exactly yeah how could you not like this
right more fun that you should have on a Tuesday
8:00 p.m..Marcello Souza - Young Stars of Tomorrow; Inclusiveness; Sky’s Up Magazine
night so Harold walk is the first one to log in on chat this
evening hello yeah Harold so we had you know today I
8:15 p.m..Nicolas Ariel Arias - Hammertime with Nico
was supposed to be on QVC well I was on QVC but I supposed to be on at 2:00 p.m.
Central and we're all s we're in the showroom you know we've got a two
8:30 p.m..César Brollo - Live from Buenes Aires
cameras set up and everything and I'm miked up and I've got earbuds in and stuff so I can talk to the show host
over at QVC and we're supposed to go on the air at 2 o'clock sharp at 2 o'clock
8:45 p.m..Maxi Falieres - Live from Argentina
sharp the internet goes down boom so we're scrambling we're going crazy and
uh we end up uh you know we have a pretty pretty good highspeed internet at explore
9:00p.m..Ten Minute Break
scientific but um we Cobble together a like one of those hotspot um connections
you know so we're like rifling through office drawers and stuff we find one of these things and gives us only 15
9:10 p.m..After Party
megabytes up and 15 down you know so we're going I don't know if this is
going to work and so they don't call us they don't call us they don't call us and so I'm driving home to set you can
see I'm home right now okay um because we still don't have internet at um
explore scientific and so I get I started getting Skype calls
that's how they contact us is through Skype and I'm getting Skype calls from the producer QVC as I'm starting to
drive home so I whirl back around we connect up all this stuff they say oh
yeah that that high-speed internet stuff that we talk about um don't worry about
that you know know we can hear you we can see you and so they put me on so that saved the day but
uh anyways very glad to hear that and hello Adrian hello David Karem Mike and
Jerry and Scott uh hiding behind hi this
is the famous Dr Adrien Bradley photographer yeah it's uh early on yet
maybe I'll get there I just have to keep up with the passion of doing this oh we don't have to anymore do is giving out
honorary degrees Yeah I if it comes from D then it's
official and I will I will hang that on the
wall that's right so so you know Scott it's almost time I keep trying and trying with this uh star Adventurer and
um my tracking is off so pretty soon I'm G to have have to uh finally go and get
the explore scientific uh one of the small tracking mounts that you've got and start showing it off pretty good
luck with it um so far so
uh you know the we've had we had a guy get like3 Arc seconds of uh tracking
with um of course with guiding you know so yeah but um yeah guiding would $500
Mount yeah well $500 to a guy who's had to spend
2,000 on the camera um the mount would be worth um being able to track for a
lot longer than I'm getting right now so it's either that or haul out a losman be
Mount and figure that one um I'm going to I'm going to go with the smaller
Mount because I I like to travel and I like to just pick up the whole tripod throw it in the truck and go so
sure is that Adrian yeah it is me Tyler what's up buddy doing
good so speaking of guiding on the isos 100 um Jerry can attest this because
I've told him the same thing I've been able to get with this setup that's back here behind me yeah um
04 okay second for guiding um it's just with a rough um a decent
polar align but rough balance I just make sure that my tripod's level people that say that it doesn't matter they're
they are full of it yeah I mean it all matters every it's the fundamental that
you have to start out with but just balancing it's the way they say it doesn't matter if you do it the way they
did on meatballs you just go up and you say it just doesn't matter it just doesn't matter
but I mean this this little thing back here Adrian if I can walk you to it how to set it up um I use the eagle or the
eagle I'm sorry the ASI a up here yeah and it's it's it's it's dummy proof it's
literally dummy proof and it makes it simple um especially since you travel and that's the reason why I got this is
for just the ability to travel anywhere and just set up in a matter of
minutes that's the goal yeah I'll have to uh I'll have to stay in um check out
your uh present when where are the presentations by the way let's see Tyler so yeah you come on after the break so
I'll be hanging around and uh checking out the presentation so what I'm able to
do with the star Adventurer used to give me a minute up to two minutes
untracked um there is a chance that I might have beaten it up a little bit
going here and there and having it right in the back of the truck but the tracking right now barely does 30
seconds and that's uh if I do half cederal tracking so I can have a single
frame um I still have these annoying star Trails so I'm I'm still trying to
figure out if it's the lenses that I have or just the fact that um I'm I'm
just not tracking very well and I've tried to make sure it's all balanced and everything like you said that there
tripod is level how's the what camera are you using I'm using a Canon 6D most
of the nights uh so full frame yep so full frame yeah all I have is full frame I put on there if I'm not using that I'm
using a A7 R4 from Sony which is recently jumped in and stolen the crown
of unmodified camera to use for um wide-angle shots so um if the 60s
modified so if I want the afro around Orion's head I use the 6D and uh Bernard's loop I think it's
Lambda Orion this is the official name of the uh title but I'm I want to submit
Oran afro to the IU and see if uh see if they'll allow that I'm I'm sure I'll
have a fight on my hands but I think it I think it m it is in fact now I'm going to pull out an
image um so that I can show that if I'm within
my time I can say see you to [Applause]

well hello everyone this is Scott Roberts with explore scientific and the explore Alliance and welcome to the 74th
Global star party uh with the theme of Look Back Time look back time is a a
term that's given by astronomers uh to describe the effect of
seeing something at whatever you know whatever distance it is however long
light took to travel to you that is the look back time so if light took uh um a
couple of seconds to get to you then the image that you're seeing of that object
is two seconds old it's not in real time but as we look further away you know
maybe a few mile you know you know out to the distance of the
Moon or maybe out to the planets now we're starting to get out to light
minutes uh I think it takes eight minutes and change to for light to get from our Sun to the Earth uh when we
observe the sun we're seeing it eight minutes ago um when we turn our sites to
the Andromeda galaxy at 2.2 million lot years away we're seeing Andromeda as it
was 2.2 million years ago and also uh at the
observable you know distance uh of where it was 2.2 million years ago so we know
that we're on a collision course with the Andromeda galaxies so if we could see see it in real time things would
look different to us but we don't see things in real time and that is the look back time it is a concept that
fascinates a lot of people because uh when we see a supernova or something
explode in a galaxy we know that um if that Galaxy is millions of light years
away that that supernova star took off
uh or or exploded that many millions of years ago uh
fact that we're getting those photons the real photons during you know during that that episode doesn't mean that uh
that you know that effect isn't with us anymore it is but the star itself in
real time is maybe not there or some remnant a black hole or neutron star or
something is there in its place so and anyhow it is very fascinating uh it's
something that I bring up a lot during uh astronomy Outreach programs uh and uh
is just one aspect of uh of uh understanding the universe that you're
observing well tonight we've got a great program lined up um you know we're close
to Thanksgiving uh so uh some some of our friends are not with us uh but
others are and they've made that commitment so we're really happy to have them of course up next is going to be
David Levy we've got uh Chuck Allen from the astronomical League he'll be with us
uh Kareem Jaffer uh from the Royal Astronomical Society Montreal Center
Royal Astronomical Society of Canada Montreal Center will be with us uh Adrien Bradley with the skyscapes Molly
Wakeling is uh committed to be with us uh hopefully everything's working uh
where she can show us live Imaging from her backyard uh uh Mike weasner is going
to be talking about dark sky with us out in Arizona we'll take a 10-minute break
and then we'll come back with Tyler Bowman from his his Observatory uh Jerry Hubble from his
Observatory Annie Scarboro uh who's uh not yet participated on a global star
party uh will be talking about exploring the stars with with their family so that's pretty cool marchel Souza uh from
Brazil will be on with us and he'll be talking about the young stars of Tomorrow program uh their
uh program of inclusiveness and Sky Up Magazine uh Nico the Hammer Hammer Time
with Nico will be on uh Cesar brolo Maxi FES all three from Argentina will be
very interesting and then we'll take another 10-minute break and any Afterparty that might happen afterwards
but uh we're glad you're with us um uh I may or may not have mentioned that I'm
broadcasting for my home and uh the reason for that is that that the internet is out at explore scientific so
so I had to reconfigure everything for here but um we got a great audience too
uh watching Pekka's on uh we've got Harold lock uh J Jacqueline aren't and
uh the dad frequency lisanne Fanning and others are watching so welcome to Global star party and I'm going to turn it over
to a uh fabulous person who has just now made us all honor given us honorary phds uh Dr David Levy
um so that that's great we all wanted a PhD tagged on to our to our name but uh
David thank you so much uh it's we're it's great to have you on for yet another Global star party and uh you've
been really really busy I know um doing other events and uh everybody
appreciates uh having some uh David Ley time so so we'll turn it over to you
David well thank you so much Scott and I canot can no longer say that I've been
to all of the global star parties I did miss one missed one I did miss one and
uh uh which kind of I still feel feel pretty bad about that but it's because I
was not it was it was not your fault it was not your fault but I'm feeling bad about it and uh like to make up for it
somehow he will make up for it anyway I'm I'm glad to see that all a lot of my
friends are here Jerry Mike and Adrien and uh and Kareem and Tyler and Chuck
certainly from the astronomical League um Adrian you did mention during
our uh informal thing just now that you were you you were going to try to photograph an area on Orion and you were
going to try to give it a name for it and you were hoping that the IU will accommodate that
well I to suggest that you don't need the IU to accommodate you on that you
can just make your own Adrian's catalog I've done that there's no reason that you can't do that right so it's
done any um as we get into this Global start party the two poets that I think
are most inclined to write about time are Shakespeare and
Tennyson we've talked about Shakespeare before and about Tennyson before I
really wish I had known Alfred Lord Tennison I do know his great great grandson Jonathan Tennison who is an
astronomer and who's done a paper on commentary maker leing n and uh I did get a chance my last
visited to London to meet with him and uh I really I really think that family
is still very interesting and very well worth knowing but Tennison I
think Alfred Lord Tennyson was really tops when it came to writing about time
which is our theme this week and I think there's no better poem than he did that than in memorium which
is his definitely his magnum opus and I'm going to I'm going to share three
passages from the memorium tonight one is pretty simple it's about the
discovery of Neptune and it goes like this a time to sicken and to Swoon when
science reaches forth her arms to feel from world to world and charms her
secret from the latest Moon little thing about Neptune there he
wrote this in 1850 Neptune was discovered only four years earlier the
second one is really where he gets into Evolution and talks about time
contemplate all all this work of time the Giant laboring in his youth nor
dream of human love and truth and dying Natures Earth and lime but trust that
those we call the dead are brothers as of an ampler day forever nobler ends
they say the solid earth where on WE tread in tracks of fluent heat began and
grew to seeming random forms to see in prey of cyclic storms till at the last
arose the man who throw and branched from climb to climb the herald of a
higher race to shape and use arise and fly The Reeling fond the sensual Feast
move upward working out the Beast and let the ape and tiger
die I have one more passage from M memorian to share with you tonight and this is the last four lines of the
poem and I believe that in this these four lines Tennison is doing a
teleological discussion in which she she actually
discusses in the inmemoriam stanza if the universe will be expanding
forever and this is decades before Hubble not Jerry Hubble who we have here
but Dr Edwin hble came up with his theory of the expanding universe and we still aren't sure if
it's going to expand forever or if there will one day be a big crunch and I believe that Tennyson felt
in 1850 that there would be a big crunch and this is how he ends in memorian that
began as a simple elery towards a friend of very dear friend of his who passed
away at a very young age from a stroke and he starts with that but then
he goes on and talks about where the universe is headed and I want to end my
quotation with this that friend of mine who lives in God that God which ever
lived and loved one God one law one
element and one far off Divine event to which the whole creation
moves and back to you Scott thank thank you thank you so much
wonderful is Tennison one of your uh favorite um oh yeah I think so I think
next to ten to Shakespeare and jard Manley Hopkins tennison's my third favorite PLL it I see I see well great
so do we have Chuck Allen here with us we do we do okay all right that's great
uh let me go ahead and bring you on here and um there we are and I see you right
there we're going to add the spotlight to you and uh thanks very much David and
uh we will figure out um I'm GNA figure out something very special for you uh
that will be a special edition of global star party so more to
come all right well Chuck uh I know that you've been super busy
um uh you know I I've heard uh that uh
you are uh you're very involved with some special projects right now Terry
man was letting me know yeah I'm uh in the final week of getting a draft of a
book to a publisher u a royal royalty publisher um and uh it's about a shark
attack victim it's an authorized biography of a shark attack victim in South Africa oh goodness and covers
about eight shark attacks among his friends two or three of them fatal and fully interviewed accounts of those and
basically life in South Africa post aarte and and a little bit about surfing
culture all kind of woven together oh goodness were you uh were you involved
in surfing yourself at all no no and having having written this I will never
be involved in surfing you will never be involv that's right um uhuh a lot more
dangerous sport Than People realize for a variety of reasons not just sharks sure I did it as a you know young man
but uh it's it's a thrill for sure yeah but yeah there there were there
everybody that serves has stories so for sure well Chuck thanks so much for
coming on us for the astronomical league and uh so let's goe and get started all
right let me share screen here it's not sharing there it is
okay whoops there we go okay as usual folks
we we like to uh help preserve and save people's
vision and vision can be jeopardized by astronomical Pursuits that involve
observing the Sun so we like to give These Warnings whether we're talking about the sun tonight or not uh because
you might be around a telescope or you might have kids who around a telescope or a pair of binoculars when the sun is
out and that can be dangerous you don't ever want to leave a telescope or binoculars unattended around children in
daytime uh if you're going to use any type of uh if you're going to observe the sun you need to use professionally
made solar filters that include energy rejection filters at the top end uh the
front end of the telescope not any kind of filter that goes on the eyepiece um and you if you're using
eclipse glasses to look at an eclipse of the Sun a partial or hopefully a total at some point the eclipse glasses are
meant to use alone not with binoculars or a telescope that's right Expo expose
eclipse glasses as Scott Roberts can tell you uh to a telescope beam aimed at the Sun and they will melt almost
instantly and you don't need that kind of problem so with that said we'll move
on these are the answers from the November 16th Global Star Party
within the large melenic cloud is n44 and what was notable about n44 and the
correct answer uh is that uh was notable for its hollowed out core uh this core
is some 250 light years wide the hole called the Super Bubble is a cosmic
Enigma the second question was what plans is the orbital assembly Corporation announced for 2027 and
that's a space hotel for those of you whoever ever saw the movie 2001 this will look somewhat
familiar what well-known chefs helped NASA pick the winning teams for a second
phase of the deep space food challenge the answer was Martha Stewart and Lynn
Crawford okay now your answers need to go uh to
secretary at astr league.org I'm going to get to the questions in a moment uh the correct answers for November 16th by
the way were these individuals uh Rich Eubank Don NAB Cameron Gillis rich kaying and Israel
monteroso so congratulations to them they will be added to the door PR list for the end of the
month okay here are our questions for tonight once again at the bottom of each
slide you'll see where to send your email with the answers first one this long dark feature
called a filament is actually a what is it a prominence a sunspot
a solar flare a spicule or a chromospheric
arch okay okay number two of the primary eight planets in our solar system how
many have ring systems two three four or
six and number three speaking of Look Back time gnz11 is the furthest Galaxy
ever observed we're seeing it as it looked 13.4 billion years ago how far is
it from us now it's 6.7 billion Lighty years away 13.4 billion light years 32
billion Lighty years or 1.34 trillion light years and those are the an those are the
questions for tonight and I'd like to whoops mention that we will have a live event number 13 for the league on
December 3rd our speaker will be Matt Penn and he will be talking about the dynamic Eclipse broadcast initiative so
I hope you'll join us then we have great speakers for these Scott thank you very much and I'll turn it back over to you
thank you very much uh I would like to uh you know mention that uh the
astronomical league is um uh someone that or an organization that we've been
um uh you know closely allied Allied with and um uh we we believe in all
their initiatives that they do uh they have great observing programs uh they um
interact with the community I think in the best way uh not only you know friendship and all of that but uh
through education uh through a lot of hard work in their almost all volunteer
program uh and they are the largest organization of their kind they have over 300 member clubs that belong uh
that are part of that Federation of the astronomic IAL league and uh over was it
20,000 members so um you two can be a member of the astronomical League
through your Club here in the United States uh or um you can anywhere in the
world you can be a member at large and so uh you have no no further uh to look
than the website astr league.org so thanks so much uh uh Chuck and um you
know uh we'll we'll see you guys next week great thank you thanks SC for all you do for us thank you so much thanks
all you can do for everyone um okay so uh up next is uh Dr Kareem Jaffer uh he
is with the Royal Astronomical Society of Canada Montreal Center uh and also at
John he's a professor at John Abbott College uh he is the uh astronomy
Professor that we all wish that we had uh so I'm going to turn this over to you Karine thanks Scott and not a doctor not
a doctor not a doctor but a newly minted got honorary from uh from Dr Levy
today so I did I did and yes as Adrien me mentioned I'm now a member of the lowbrow Astronomical Society in Michigan
and uh so I'm a member of the astronomical league as well I'm now wearing even more hats right it's more
fun that way right that's right um I was so happy when when Scott put the time of
the the topic of Look Back Time uh we talked about this a few gsps ago but I
felt like there was some so much more to talk about and so I got really excited and started putting together the
presentation I wanted to give and then I had my class today and my class today
kind of took things a little bit sideways during class and then after class with some discussions with some of my students and I decided to bring you
on a journey with the perspective from Jack astronomy about Look Back Time the
last time we talked about this I actually talked about look back time within the solar system but what I talked about was not just the amount of
time it takes for light to get from the Sun to the solar system planets but also the amount of time it takes us to
communicate with probes that are studying different parts of the solar system and the amount of time it takes
the light to actually leave the sun tonight we're going to go a slightly different direction but as always before
we do I wanted to do a check-in with the Montreal Center and invite everybody in the audience to join Jo us for our next
public event which is on Saturday December 4th 4M eastern daylight time and it's on Apollo moonrocks and we have
a graduate student Gavin tedi from University of Western Ontario who has
been researching a little bit on some of the past Apollo missions the history and then he actually got to be involved in a
little bit of the research using current Technologies to investigate these moon rocks so he's going to talk to us a
little bit about what we understand about the geological history of the Moon based on all of these moon rocks that
we've had come back from the moon so you're all welcome to join us for that and as a lot of you have noticed over
the last few weeks I've been bringing in guests from the RC Montreal Center as well as the RC as a whole to come to the
global star parties and be with us for the evening share with us a little bit of their wonderful insight and
unfortunately the speaker we had lined up for tonight to join me qua Tran he
lost his voice he's been struggling a little bit with the cold that he's been fighting and so Qua we wish you the best
for a speedy recovery and we hope that you will join us for one of the future Tuesdays but uh our Outreach coordinator
Russell freck is going to be coming on next Tuesday to talk a little bit about uh backyard astronomy that he's been
doing but it's right after our lunar eclipse I wanted to talk to you a little bit about our journey here in the
Montreal center with the lunar eclipse on November 19th uh Adrian and I were both also participating in the virtual
telescope Project based out of Italy with Gan Luca Mass and so we were trying to take pictures and send them in real
time so that they could be shared all across the world and the evening the forecast was not great Montreal forecast
never is but it started out actually pretty good I even got a little bit of penumbral Shadow uh this was at around
1:40 in the morning so before it had actually started Crossing into the Umbra and you could see just a little bit of
the dimming compared to what the full Moon looked like at around midnight when it hadn't come into any part of the
Shadow yet and then you got to see the start of the eclipse you got to see the
Earth's Shadow starting to fall on the face of the Moon you even got to see the curvature of the earth visible to us and
this was fantastic to see and I was so happy and so excited and then the clouds rolled in
and when the clouds rolled in they started to take over dramatically before even half the moon's surface was covered
with Shadow and so I was you know still online and talking to Gan LCA and
messaging a few others that were involved in the project and watching views from places with much better
weather but one of my students decided that she kind of started to understand what it is to be an astronomer and she
was going to be patient and she was going to wait and I'm very happy to report that Vanessa tomasini got a
picture just after maximum and I was so happy for her and so we shared this with
the world uh with the virtual telescope project but we also sent it out locally
and on the Sunday night news they actually showed her image and it's the clip that's the thumbnail that they used
for their clip to talk about the lunar eclipse so I'm very happy because this actually got not just her excited for
what she saw but it also got to be shared with our local community in Montreal and all over the world and
that's one of the things that you really hope when you're trying to share some of this passion that we have for astronomy
and for amateur astronomy is that that some of that actually translates over to the students so talking about the moon
when we're talking about look back time we have to recognize that what she was taking pictures of what we were seeing
was actually leaving the moon's surface just under a second and a half before we got to see it but that light didn't just
come off the moon's surface It's been traveling since it left the sun's surface 8 and a qu eight and a third
minutes before so you know it travels a bit bounces off the moon comes back to us we capture in our camera we upload it
we send it to each other and then we drop it off into a Dropbox and then in Italy they put it up on the web that
takes a certain amount of time that's not exactly what we're considering when we talk about Look Back Time in
astrophysical senses in astrophysical senses when we talk look back time we're talking look back time we are talking
about looking far off into the distance beyond our solar system looking at the
deep space objects and looking as far as we can can possibly see now groundbased
observatories in the 90s were able to get out to about a distance of 6 billion years which is phenomenal and earlier we
were chatting a little bit about the the resolution that some people can get now with their observatories or even with
their backyard telescopes at that time the faintness of
light the size of telescopes that you have the atmospheric opacity of the Earth all of that combats how deep you
can see when Hubble Space telescope went up it expanded our vision and the Hubble
Deep Field got us much much further out to just 1.5 billion years after we think
the cosmic Dawn just after the big bang when electromagnetic radiation actually was able to start to uh be released out
of this radiative mess that came when the Big Bang had happened the ultra Deep
Field and the ultra Deep Field infrared all got us further and further and we're really hoping the James Space Telescope
has a tiny setback right now and the launch date's been pushed back by a couple of days but we're hoping that
once it's up and running and everything's running well knock on wood fingers crossed whatever you know walk
three times counterclockwise whatever you have to do for Superstition we're really hoping that we get fantastic data
out of the James web Space Telescope but when we're looking this far away what
we're actually trying to look at is not the material the way it is now we're trying to look at how it was when the
was released from those objects so when Chuck talks about this most dist Galaxy
that we're looking at it's important to recognize that everything you see the image that you're
viewing that light left that object a certain number of years
ago and so when we're looking six billion years out into the universe
we're looking at something the way it looked six billion years ago and it's been moving ever since then
and so since it's been moving ever since then where it is now in the scale of the observable universe now is different
from the amount that we can actually visually see and so when we talk about Look Back Time the astrophysicists and
the astronomers are really trying to deal with one of the most complicated things the hardest thing it is for any
astronomer to measure when an astronomer goes out there and they set up their telescope whether it's a radio telescope
whether it's a Space Telescope or whether it's your own little refractor or reflector in your backyard
your job is to catch photons and figure out how to resolve the detail within those photons and those photons of light
that little bit of information that shows you what the object looked like when light left it
but where is that object is something that's a question the distance measurement is incredibly difficult and
so we have to have different tools for measuring distances and we've developed a whole set of tools depending on how
close an object is versus how how far away that object is and in 1929 Hubble released his first set of data trying to
understand the relationship between distance and the speed at which these galaxies seem to be moving with respect
to us and that was based on measurements of Sephia variable Stars which were not actually done correctly at that time but
when everything got refined and everything got fixed and since then when we've actually been able to calibrate to
type 1A Supernova when white dwarfs gain just enough Mass to explode and a
catastrophic explosion leaving nothing behind and giving an absolutely beautiful fit curve that we can actually
figure out how far away these type 1 a supernova are we have very accurate
estimates We Believe of how far away some of these galaxies are and when we measure their red shift the amount that
their light has shifted it tells us how fast they seem to be moving with respect
to us but all of that motion is not because those galaxies are are actually conect ially moving that fast it's
because the space itself is expanding and so we have been having
this discussion over the last few classes the whole idea of the expanding Universe the measurements taken by
astronomers that led astrophysicists to revolutionize our theory of our understanding of the universe what we
call cosmology and then last Thursday I had a guest speaker on Andy Briggs from Spain
and Andy and I are both on Astro radio together and he gave a wonderful talk about detecting Gra gra itational waves
with ligo and when he talked about the gravitational waves of course the very first gravitational wave detected was in
2015 and it was this binary black hole merger and we were able to determine
based on the energy signature what strength that merger
should have had so then seeing how strong it was when it got to us allows us to estimate the distance and the
distance to this black hole merger was 1.4 billion Lighty years 440 megap
parex and so Andy made a really clever joke you know he said you know on Earth at that time 1.4 billion years ago when
these gravitational waves left the only thing on earth were single celled organisms and it was probably Keith
Richard's birthday now that idea of there was nothing on Earth it was single
cell organism because it was only 600 million years ago that multicell organisms actually came on Earth well my
students just dug into that that was just a wonderful piece of trivia for them to start talking about the Keith
Richard's joke went over their heads but the idea of these distances relating to
times and what was happening on Earth at that time struck them and then I started
thinking that next class I'm going to be talking exoplanet detection and the Drake equation and the search for life
in the universe that's the way I like ending every unit before the test is talking about the
search for life so the solar system unit I end with the solar system search for life and the the cosmology unit I end
with well can we travel Interstellar can we actually go away from our solar system and go anywhere else and so I
started thinking about how am I going to talk to them about the distances to some of these exoplanets because some of
these groups are actually doing exoplanet transits as their projects the first group of mine that ever did that
was the group that did hat pieces 16b and you can see the dip really clearly
when the planet passes in front of the sun now that star is 740 light years
away the ones the current group are doing are Hat p32 B 950 light years away
and Qatar 1B which is 609 light years away 609 light years away that's the
last 69 years is the last time we had that long of a partial lunar eclipse
here in 69 years ago we had the the the era of the Incas was still going on in
South America and we still had the the belief that when an eclipse was happening it was because a Jaguar was
taking chunks out of the moon so what are we looking at and what could they
see if they could actually see Earth at this moment in time would they see signs
of Technology would they see signs of civilization would they actually have any evidence of where we are right now
as a peoples when you're looking this far away that's not going to happen but when the James web Space Telescope goes
up one of the systems that it's concentrating on is the trapz system and the trapz system has all these beautiful
exoplanets and it's only 39.5 Lighty years away so when they see any light
from the earth passing in front of the sun if there is an astronomer sitting at trapis D in the start of the goldilock
zone and looking at Earth and seeing the signature and they can manage to catch our radio waves they will see all of us
doing the Thriller dance they'll see us in the early 80s with big shoulders and fluffy hair and you know leggings and
they that's what they will see because they will see us as we were 40 years ago
so when we're talking about anything to do with astronomy it's important to recognize take some time for us to see
the signals that we see and with that I thought I'd end with this wonderful video that Scott put together for rasan
trail Center ah good thank you
all wonderful wonderful well thank you very much Karim I I too you know I am
always interested in how people react to um uh you know the effect of you know
you show them a Galaxy you tell them how far away it's it's predicted to be due
to to its red shift and all the rest of that and um and then you tell them look the photons that were made in those
stars to the action of fusion you know the atoms crushing there and they took off all that time
ago um plus you know the distance of uh
of how far it's now moved okay um it's this this connection that they
get because the phot are now hitting their eyes but now they're they're understanding they're looking so far
back into time you know uh some astronomers also call this fossil light
okay because it is so old uh it really kind of throws them into kind of this
different um framework this different position of of what they think
reality their everyday reality really is you know and so it's uh uh it it uh it
it throws them off their base a little bit you know oh absolutely and today's discussion one of the things that the
students really were were trying to get their head around was this idea that if somebody in the whirlpool Galaxy is
looking at us or somebody in a very distant Galaxy is looking at us yeah they're seeing us moving away at that
speed and they're seeing us as we were that many millions or billions of light years ago and so the concept that
there's this cosmological principle where every observer in every place in the universe they see their own local
neighborhood kind of like we do where all the galaxies have evolved to a certain point and there's a certain amount of structure involved and the
further out you look the more disorganized the more chaotic things are the more energetic things
are and that there's no we can't tell if there's a edge or a center to the
universe because everybody sees the same thing they can't get their heads around that because that is such a
unique philosophical Viewpoint and we are so and talking to them about the
fact that every single Evolution whenever we were combed with something
that went against our knowledge and we had to change our theories there were certain things that we tried to latch on to and one of those was that humans are
special and that the sun is the center of everything if not if not the Earth it's the sun if not the sun it's got to
be the Milky Way galaxy we got to be the center because there's got to be something special about us right trying
to get them to detach that from the observational evidence which tells us we
can't tell if there's anything special about us because we'd never be able to see it oh my gosh metaphysically that
just it it some of them they they are still digesting it and coming back and talking to me every 20 minutes or so
going sir my head still hurts can you can we talk more yeah yeah yeah at least their minds are open enough to try to
continue to understand it I have had people that uh absolutely reject it I
mean we got that part of it they were just like
uh it's almost scary to them you know that everything that they know and the
way they think about it okay is now changed they know it's it's different
but trying to wrap their head around it is a big deal and uh so that is something um that astronomers who do
kind of contemplate this stuff um you know cosmologists who contemplate this stuff they are um they're special people
I think you know so at least they have um in one way privilege that we we can
start to try to understand this we can try to wrap our heads around this kind
of thing but uh a lot of this is so tantalizing um uh but at the same time
very um disconcerting for some you know definitely and and just the scale the
scale of numbers that you're talking about I mean even just within our solar system when you start talking about 150
million kilometers to the sun they're sitting there looking at you going wait what do you mean 150 million but that's
just the Earth and everything else is much much much much further out the scale boggles their mind it boggles
their mind and that's that's where it becomes incredibly unique for them to
have this experience of trying to find a way to relate to the topic and to the
observations that we made because the observations that we made are still unsettling to a lot of us when we're when we're sitting there looking at it
and trying to understand it so the fact that it's unsettling to students is a good thing it's for them to recognize
and to realize that there's there's a lot out there that we don't that quote that you put forward for today was
amazing the idea that really the things that we now are understanding we can't
understand why people couldn't understand them 30 50 600 years ago it seems so obvious to now I I told my
students about the olders Paradox this idea that if there's Stars everywhere how come the the sky isn't just bright
white and that at that time we didn't understand that the intensity of light drops off as one over r squared As you
move away from these these objects so that even though there's stars and galaxies everywhere you look lightly
continue to fill up the entire sky right exactly it dissipates out in intensity
and that seems natural to us now we've grown up knowing that all of these Force laws are all one over r squared and we
we take it for granted but if you ever stop to think about it you can understand why it wasn't understood
until somebody quantized until somebody made a model that says look this makes sense now so what don't we understand
now that in 60 years people will look back at us and go how could you not figure this out like you don't deserve
this honorary doctorates let's find out who this D David leaving person is who gave you honorary doctorates you don't deserve them
no he doesn't but could I add something to what said kareim um actually one of
the first people to explain oler's Paradox was none other than Edgar Allen Poe who wrote a scientific paper about
it and I think he had the right explanation all the way back then like the early part of the 20th
century this was brilliant absolutely
brilliant I I am curious though uh uh Kareem when you're working with your
students and you take them to this point where their brains are hurting they are
now um in a spot intellectually or maybe
philosophically or something where they're in a very uncomfortable position
okay uh you've taken to no man's land okay uh is that how important is that to
to learning and making the leaps in learning at at the you know in a young
adult's life incredibly important the one thing that you need to make sure
especially when you're talking about a field that they might be interested in down the road is that they recognize
that there are open questions and that they recognize that there are approaches for everyone somebody who's just
interested in the mechanism can work in aerospace engineering or an optical design somebody who's interested in
observational data can work on data analysis for telescopes or for uh working through vibrational analysis for
satellites somebody who's really interested in the Deep philosophical anchorings can work in theoretical
astrophysics and cosmology but recognizing that there are these open questions and there always
have been no matter how we try to refine our theories open questions remain and
that's why we keep pushing the boundaries of knowledge that's one of the goals of especially postsecondary
education but I think even secondary education is you want students to realize all the answers are not in that
textbook you hold in your hand all the answers are not sitting there on Google you have to actually search for answers
and you may not always find them and that's one of the one of the most enlightening things for a student is
when they come up with an answer that's wrong but they did the process right and
they realize that okay this was not the way to get this answer that
acknowledgment that you can't always pick the right path to find a solution or to find an answer the first time is
something that not every student is exposed to and then it causes them problems down the road when they come up
against a hurdle they feel catastrophic failure they feel this this depression
that oh my God I'm not good enough this isn't my field they don't understand that this happens to every scientist
this happens to every academic this happens to everybody in every field you fail you make mistakes you don't
understand something and you have to go and learn more and so the one thing that I don't do is I don't let that be the
last class which is why next class I'm going to tie them back to exoplanet search and something a little bit more
tangible because I tried my very first time I taught the course to end with
astrophysics and it it was just for them it was too open so then I actually
called them in during the exam period when exams were done anybody who wanted to come in I'll do an optional 45
minutes and we're going to talk about some of the Practical things you can do next year if you want to keep looking up at the night sky every single student
showed up awesome this was right before Christmas so they all wanted something tangible to walk away with
[Music] right very interesting okay well thank you so much
kareim that's awesome my pleasure thank you so much okay uh up next is uh Adrien
Bradley Adrien does incredibly beautiful and sensitive uh
skyscapes um with his uh work of uh photographing the Moy way uh
Aurora comets um asteroid you know or Meteor
Falls um you know and uh putting in context our our world in there and uh uh
and and the way that he describes it the humanity of it so Adrian I'm going to turn it over to you man all right um I
wanted to piggyback a comment that I thought of just as uh my new lowbrow brother
in-arms Kareem finished the statement um real important statement about science
and you may go about a process you may not get the right
result um but it's all a part of how science works and I think that's a real
that's a real important message for those of us that are trying to um promote scientific topics like
astronomy um we've watched our world go into a world of I know everything and
this is the way it is we've watched our world as people of pushed pushed uh
agendas and pushed what what most I think realize isn't a lie is a lie I'm
just going to say it the election and everything around that we're seeing this
and as science-minded people we shake our heads and go how did it come to this
where we're not willing to try we're not willing to get out there we're willing to look on Google and the University of
Google is giving a lot of folks answers our mission and part of the reason that I do these nights gapes um it it's just
part of the mission of saying there's a re there's a reality out here that's beyond your mind and Beyond what you're
seeing on TV or YouTube or other forms of social media and it's my hope that
programs like this um that programs like this reach a lot of you and that those
of you that are on uh watching it live are sharing with others and just say you
know hey there's something out there besides ourselves and I think it's it's a great humility that if you don't learn
it from religion you can re learn it from studying the universe and realizing
we're just a small part of it and it's a said Adrian well said yes big reason I
do um I photography and I'm sharing my screen and this is an image that I took
very recently and I didn't get the results I was looking for the milk way was very
faint these were some tough conditions there were cars on the uh driving by me
and this is uh you know faint Milky Way and the Moon is rising behind me I can I
was able to turn around and see the Moon Over the Horizon as I was taking this photo most probably wouldn't try for it
because well why try to shoot the Milky Way when there's a bright moon out but
it doesn't stop me from trying to create a picture of it and it doesn't stop me from seeing if I can get a part of the
Milky Way here because I did it once before couple years ago the core of the
Milky Way was visible near this receding Moon and I got a pretty good shot on it
and this was before um this was before knowing how to noise reduce which I
would have done some noise reduction here but I was just my results I was
just happy there's uh M8 and M22 is this dot over here I was able to get a Milky
Way shot with the moon and that over here I was able to
get a Milky Way oh I'm hearing you I'm hearing a uh feedback on you Scott something was coming okay but uh that's
okay so we don't always shoot in pristine conditions and that includes
the effects of light pollu ution and I'm going to get to time in a minute I wanted to talk about that um you know
our main topic but another thing that I learned when I do night photography
Milky Way is behind here somewhere and this is these clouds are lit in a bort
four bort between bort four bort 5 Zone Milky Ways behind here somewhere you can
hardly see it um when you go to a dark site
you not only see the Milky Way but the dark the bottom of the clouds are dark black so those of you that haven't been
to a dark sky site there is a h there's a huge
difference between what you may think is dark a lot of people think that this uh
location which was Lake Hudson dark sky Park is dark um but then through Darkness things
change um and you you not only is the Milky Way just shine
through um the bottoms of the clouds are black so for those of you that haven't visited
a dark sky park yet I highly recommend it so I want to move on to the lunar
eclipse because I did get a chance to take some shots of it and um I'm going to pick up where Kareem left off when
the clouds covered his area I was in it I was in someone's backyard
where the skies were clear they cleared up in time for us to see the entire lunar eclipse so this is one of the
images this is pretty much about where Kareem lost uh the eclipse due to the
clouds but I kept on shooting I ended up taking a couple shots here we're getting
closer and you can see Tao the crater here um most of these are either
handheld or on a tripod um there's enough of the Moon to be bright enough to be able to take a picture handh
holding it using image stabilization then it got to the point
where it was around 97% and that's the image that you've seen there's three stars here four
actually that I can see had I done a bit better exposure we might have seen more
stars around this um 97% eclipse moon this brightness here was just enough to
make it a little more difficult to image however I did a couple
composits where I took a I took an exposure in the backyard there are the
pleaes the heidis Taurus and the Ryan
you might barely be able to faintly see some nebulosity over here it's called
Lambda orionis and I wanted to rename it the uh afro of Orion but more on that later but
when when the moon goes um even 97% covered the stars come out and on a full
lunar eclipse the stars come you get just that much more brightness so an
image that I've uh image I'm taking here which is an interesting take on time you have the
eclipsed moon and you have the plees star cluster that are close to each
other in sight this particular eclipse moon was near the plees um I forget how
many degrees I mean I would say seven I think with this um this was taken with
135 millimeter camera on a full frame sensor for those that are out there that know what that means it perfectly framed
the plees and the moon together there are some other very beautiful images of
this some of them are may may or may not be anatomically correct depends on where
they put the moon but there are some gorgeous images with a fully exposed pleades with the nebulosity and
its void here and you've got the eclipse moon
um now the interesting thing is this Moon
is um 238,857 miles away in the PES that light
reached us after 424 years 424 light years away so when
contemplating time looking at this image we're seeing what appears to be
something that's happening at the same time the plees light is reaching us the
light from what little light we have from the Moon and then the Shadow the uh red shift of the uh Earth all the other
lights scattered out and Shining red on this moon it's hitting us at the same
time but different time scales in light years versus the moon so when the moon
changes again we see it within a couple of seconds anything happens any of these
stars were to explode we wouldn't know for 424 years if it happened at that
instant so that's it's just something interesting and then all the stars that are in here if they went out today these
stars have various distances from them if we replate Sol them for them we would
um we would find out when they would disappear or change would be a matter of
the number of light years that they're away from us so it's very interesting when you think
about the differences in the time scales as the uh Shadow the moon comes
back that it was setting it was heading towards um our Horizon and this was one
of the shots I decided to take I took a few of them this is one that turned out pretty good once again
handheld and you have it's you see the uh curvature of the earth as it's
letting go of the Moon and then finally um as the sun is beginning to
come up on Twilight I took this picture of the fully freed full moon um I know
one of the answers I believe for astronomical league is whenever the moon
happens to be in the ecliptic um when it lines up with the
solar system ecliptic it it can be eclipsed and you can have lunar and
solar eclipses this is a similar location to where Mars was sitting I
I've got that image somewhere around I could I think I I have it somewhere it
Mars is not far I'll just click on this one again when Mars was close to the
plees Mars was somewhere around where the where the Moon is and I wonder if
just the Moon being along the line of the ecliptic is what made that a possibility that it
might end up in what is almost the same place that Mars and some of the other
planets end up in in relation to the plees so I found that bit of symmetry
interesting and let's see finally we talk about
time um couple of images that don't have anything to do with space but um it
looks like we're bending time but I think that was a function of my camera um these gentlemen don't even
realize this Ball's been fouled off yet he his glove is staying there I have another image with the foul ball off
this way um how quickly professionals swing the bat an instant like this we
see it instantly if we're sitting in the stadium however we still don't know if
anything happens here we're not going to see it for 424 years Bal juice we're not
not going to see whether or not it explodes sometimes we get lucky and we can capture an instant where right
before a bird enters the water after prey this instant is so quick you blink
and you miss it but when you're talking with space you blink you blink some more you
come back the next day and it looks the same and then somewhere over here Beetle Juice it could have blown up in an
instant but we don't know that the the difference between what we see with our
own eyes on Earth versus what we see in space it can be a very
remarkable thing to realize that I guess relativity time how vast universe is is
at the same instance someone can hit a foul ball and we don't notice it until
we see the ball all the way back to the back stop something could happen in one
of these Stars in that same instant but we wouldn't see it for years and years so that's something to contemplate and
I'm going to end this segment with my bid to make Lambda Orion is here call it
Orion's afro I have plenty of pictures of Orion's afro here's Orion's afro and
zodiacal light well you heard David Levy you don't need permission from the IU or anybody you just make it and publish it
so well that's what I'm gonna have to do all these pictures I'm G to publish it and I'm going to
draw a line and say this is Lambda orus aka the afro of Orion and Barnard's Loop
I'm gonna call it a sash I'm still gonna call this the rosette and I think this was a camera artifact I'm not sure this
is actually anything but and I'm gonna still call this a beautiful scene in one of my favorite places the image um final
note those of you that are using modified cameras here's the original shot of my modified camera with all of
the pink I yes I could use a flat for those of you experienced aset photographers I'm working on it but
um if you change your white balance to
around 27 mine goes down to around 2700 Kelvin and then move the uh tint more
into the green area you get what looks more like a true color image so those of you that are thinking of modifying your
camera so you can take photos like this and get all the hydrogen Alpha data in
your shots um those are some of the things you'll have to consider so Scott I think
I ran over time a bit but um I enjoy talking about the various
things I like to image Outreach is something I love doing um and
so it's just part of what I part of what I do to try and share my own
understanding of the universe and how um you know how it affects me so hopefully
hopefully um those watching got something out of it and um and that's it
I'm turning it back to you
Scott uh up next is Molly Wakeling she is um uh Imaging live from her backyard
uh she's uh she's not able to come on as frequently as she has in the past but
she's very very busy studying and um uh getting things done in in uh you know in
in this time in her life and so if I say something first for a moment oh of course no problem yeah go ahead I'm
still trying to get my Target in the right spot okay sorry sorry Molly but uh
I know that I really should discuss this with you in advance but it's it's pretty harmless uh this Sunday we are going to
have a group getting together over Zoom a group of Junior astronomers we're
hoping to get a group of people aged say
10 to 17 or so on Zoom it's going to be uh at on at um 10 it'll be starting at 3
o'cl my time which is 5 o'clock Eastern time 6 o'clock Scotty's
time I was wondering Scott if I were to send you a link to that meeting this
Sunday and if people in the audience tonight would like to attend they write to you and you could forward them that
link would that be acceptable to you oh of course it would yes and so if you are interested in
attending uh you will just send a email to explore Alliance at explor
scientific.com I'll put that right down here and this is for uh the Sunday what
is the event called it's actually uh the junior astronomical League it is um I
know I'm jumping the gun here but uh we're trying to get a it's a group of people it started in Denver it actually
started when I was a Youngster in 1963 and I am trying desperately to
preserve the magic that attracts young people to astronomy it attracted me to
astronomy and I never lost that magic but so many of us do as we get older and
we get to adults remember that famous Peter Paul and Mary song Puff the Magic
Dragon the final words the final verse a Dragon lives forever but not so girls
and boys I'm trying desperately to preserve that magic that little girls
and little boys or not so little boys and girls can keep in astronomy we'll be
meeting on Sunday afternoon and uh we'd like to invite you to come if you're
interested send you the link okay well that's a worthwhile uh uh Interruption
no problem David thank you so much man thank you okay so um uh Molly Wakeling
is with us uh Molly are you uh how how is it from your side uh I let's see let
me just move this to where I think which one of these I think it is based on
looking at at stuff um yeah okay so uh I love love love love
the topic uh this whole topic of of tonight of um the fact that when we look
out in space we're looking back in time and what that means and just how
staggeringly big the universe is and how far away we can see things even from our
little itty bitty ground based telescope sometimes um so I it's been on my list
for a while to image a quazar but I haven't gotten to it quite yet uh they
don't really make for pretty images because they really they just look like stars which is why quazar short for
quasi Stellar object um but I I decided that for
tonight it would be good if I could maybe get one in my live view so I went ing on astrain for one that was of a
bright enough magnitude that I can probably catch in some five minute exposures stacked and stretched on my 8
inch schmi Crain which is not the right there we go that
one the wrong one there um which is currently out in my backyard here in
Dayton Ohio and the moon hasn't risen yet so uh the sky quality meter is
reading I think it was reading 18 .97 last I checked which is not uh
amazing but is about uh it gets about to 19.10 at the best around here uh a good
dark sky sight's like 21 or something like that so not real uh dark here but
21 is perfect I thinky yeah yeah so um it might sound
like a small distance away but the difference between 19 and 20 on a on the dark sky scale is pretty vast um so
which makes sense um but of course it's not the springtime yet so but I did manage to find one that is in I think
it's in Draco if I recall um and it is uh has a the clever name of kuv 81217
plus 6419 uh that number comes from uh its
its coordinates in in ra and deck of of of a sort um so I in order to figure out
which thing it was in here ordinarily I would go and upload this some plate solve and stuff like that but for lack
of time because I just got home from work a little while ago um or from school um I found a picture on astrain
of somebody else that took it and just kind of triangulated the coordinates of the stars look you know basically star
hopping but on a picture and I think this is it it's a little hard to tell
because my picture is inverted from theirs and some of the stars are brighter and theirs and stuff like that
but um there the the PK 94 plus 27.1 there's supposed to be a planetary
nebula here but it's really really dim planetary nebula so I'm not I'm not picking it up right now um actually can
see where my mouse is because I'm pointing at the wrong screen um yeah so there's supposed to be a
planetary nebula like here um but I yeah I can't see here but I I think
it's either it's one of these three stars I think it's this one it's it's a magnitude
14.1 quazar and it is 3.1 billion Lighty
years away if I'm looking going back and double- cheing my numbers here um yeah
3.1 3.1 billion light years away so so
that's with a B so like we have H galaxies that we could see pretty decently in the telescope like the world
poool Galaxy that's 25 million Lighty years away and and um uh like m33 which
is three million Lighty years away so this is
um uh like three orders of magnitude farther away than uh yeah it's it's it's
so far away guys yes a thousand a thousand million
Lighty years away and moving further away all the time so yeah so you're
saying it's further than from here to Los Angeles a little bit yeah yeah so we're seeing so um quazars
are are ridiculously bright galaxies that are so like ordinarily galaxies
that are three billion light years away you would need like the Hubble Space Telescope to be able to observe and Hol
telescope does observe galaxies that are even farther away than that but with
amateur gear you can actually see some quazars because they're uh because
they're they're so much brighter than galaxies that are at that same distance because of their very luminous active
Galactic nuclei and so that light's been traveling well it's not even necessarily
been traveling for three billion years because space has been stretching in that time so it's actually been traveling for longer than that
um you know if I had time I would have done the math on that but just got back so I didn't get to do the math on that
um and yeah it's just it's it's so cool to be able to with amateur equipment to be
able to and actually there are some quazars there's one that's like magnitude 12 that's I can't remember
where it's at but um I've seen it in like a big dobsonia at the Texas Star
Party there are some of these that you can see visually which is even cooler
because that light like was emitted like before the earth was formed in some
cases and here it is is getting absorbed into our retina in the modern day so it's just
crazy yes you know uh I think the first quazar I saw Molly through a a I had a
13.1 inch dob um was quazar 3c273 oh
yeah yeah and to know I mean that's 3 point whatever billion like years away
and it looked like a uh you know beautiful turquoise blue star
you know and I remember telling a friend of mine that was an astronomer at the
200 in at Palomar he says you know what's interesting he says they look like that through the 200 in as well he
said they're so far away that they're just pinpoints of light you know yeah so
really cool stuff but uh well that's awesome thank you Molly for coming on yeah you're
welcome and my my other telescope is still uh still cooling the camera so I haven't started running it yet um
so I might have something else to show a little later you want to pop back what what Target are you gonna
shoot at yeah so um well so on on this scope that I that I'm looking at the
quazar with now as soon as we move on to the next speaker I'm gonna turn the sequence back on and I'm Imaging the
Pelican nebula and cool um the uh oh
gosh it just left my brain um the heart the the heart of the heart so that like
core the core of the heart nebula and uh I'm Imaging those in in Hubble pallet
because I just recently received a full set of test filters from opal along with
their the new 3 nanometer um neuroband filters that they're going to be offering soon so I'm
gonna test those out and write up an article about it and I'm hoping that they're really good because they're uh I
might buy their sulfur filter because the chroma filter to complete my set is really expensive right now super
expensive yeah the opong filters are a lot more reasonably priced right now so
we'll see and then on my on my Takahashi I am
Imaging on my other rig um sharpless 2 115 which is a
um uh just like an H2 region a cool uh large nebula the flame in the horse head
nebula and IC 342 which is a actually a pretty a pretty large Galaxy from our
perspective but it's in the plane of the Milky Way so it's really hard to see CU
it's um heavily extincted by the dust that's in the plane of the Milky Way so
it kind of has a very yellowish color isn't that sharpless object near the 37 cluster is that an Orion that you're
shooting uh no this one's not an Orion it comes a earlier let me double check
um okay yeah there was a different it's in it's in signis uh like a lot these
guys are and yeah it's just a cool looking um sort of nebula region that is a really good fit for
I've got a um one of those Duo band narrow band filters on here with my color camera that is um the optal along
L extreme and that one I actually own and um yeah it it put out it puts out
some nice nebula images especially from in here in the city okay yeah it's cool and interesting
about the the uh Pelican I'd done some Widefield with the North American and the Pelican nebula
the Pelican was always just this blob after seeing a Hubble image of it and
then going back to some of my images I finally saw the shape of the Pelican and
I can little antenna yeah and I can best describe it as it actually kind of looks
like a football mascot type of uh Pelican with the big beat coming out in
the eye you know kind of a cavity within the the uh nebula itself so it it was
just sort of an aha moment when I uh and then I went back and I said yeah there's the shape of it right there in my own
little crummy little image but um it's like yeah that's uh now I see why they
call it the Pelican it's got a really cool like in narrow band in hydrogen especially it it yields a lot of very
fine detail and it's got these two what I always kind of Imagine as antenna kind of sticking out of it and even on on
amateur Scopes you can resolve a lot of detail in the hydrogen Alpha channel on that and I've imaged it before in
hydrogen and oxygen and uh I wasn't really happy with the way that it ended
up coming out um my hydrogen image of it by itself was really gorgeous um like a
black and white starless monochrome image but with the Hubble palette it it looks really cool in Hubble palette so
we're looking forward to to doing some Hubble pallet processing on that other yeah we're yeah we're looking forward to
it um after your so many hours of integration how many hours you plan to put on it um probably like a 20 or so
you're gonna 20 to 30 yeah so we'll we'll see you in January when you finally process this image be a while
forward to it you gotta get a lot of hours when you're under bordal 7 SK so yeah but that's uh well that's the way
it is you've you've got the equipment to do it so I might be able to get away with with less maybe like 10 or 15
because these are very narrow narrow band filters only three nanometers so okay um we we'll see how long my
patience holds out for well we all know a struble is 30 hours so if you make it to a struble
there's a special door prize or something yeah I've only gotten I think two images over 30 hours before one was
an incredible dumbbell image that I made in hydrogen and oxygen that I am super super proud of so yeah all right Scott I
don't have any more questions all right sounds good okay so up next is Mike
weasner Mike is a champion of Dark Skies he is an Enthusiast of astrophotography
and astronomy amateur astronomy of all different kinds uh he is fascinated with the night sky um and he is working
closely with us right now to uh put together the next Arizona dark sky star
party that will feature David Levy and a number of speakers um Mike Weisner lives out near
Oracle Arizona where it's dark uh where you can see the G and shine and the zodiacal light and of course the Milky
Way but uh we're going to talk about Dark Skies in general and uh and what
it's like out there near his home it's all yours Mike thank you Scott
appreciate that um yeah we got dark skies in it really dark tonight because it's cloudy so that make it even darker
even darker and and the moon hasn't quite come up yet either so I'm GNA share my screen I got a few little
slides I want to show uh let's see if I can do the right one here it looks like
it hopefully uh that's it all right so uh we're going to talk
about Oracle State Park which is in here in Oracle Arizona in the United States and it's an international dark sky Park
so along the way we're going to talk about light pollution and some other things and then we'll talk about the
park um this picture was taken a few years ago I think it was
2015 um from the park showing the Milky Way obviously that little orange glow
that you see at the bottom of the picture is not Sky glow it's not uh
light pollution from a city it's actually smoke and fires they were up the
mountains about 100 miles east of Oracle at that time so uh added a little bit of
uniqueness to this picture I did a video of the mky way rising and you can see
the Flames kind of popping up and down like the smoke blowing along there at the bottom which was kind of an
interesting video unfortunately uh but uh no problems right now with any fires out here so for those of you who don't
know me I thought I'd take a few seconds and just kind of introduce myself a little bit more than what Scott said um
I haven't been on a global star party for several months I guess although I've been on some other explore Alliance Live
Events and I've got one coming up uh with Tyler Bowman I guess in a week or so hopefully so we'll see you all again
on that one anyway so who am I well I've got a degree in astrophysics from Indiana University many decades ago uh
and a little bit of Look Back time I've been an amateur astronomer for many decades the picture there on the Le was
Easter Sunday morning 1962 uh with my brand new Christmas present from 61 uh from my mother an
Edmund Scientific 3-inch Newtonian telescope Mike you're still on your
first slide I think from oreg Street Park um that's weird because I'm showing
the thing again well let me unshare if I can um yeah I think you're you're
showing uh we're seeing you not in presentation mode so if you have a second screen you might have uh grabbed
the the wrong screen oh okay well let me uh let me see if I can get out of
sharing here yeah that's the that image you just had was the one
that I think you were talking yeah that's what you were talking about yeah but go ahead I think yeah try
again so seeing that one right there so we're so we're hit the um present uh yeah so
we're seeing your like the PowerPoint not the slides full screen oh uh do you
have do you have two screens no I just have one that's what's kind of bugging me um let me try one more time all right
uh if not we'll do it the other way yeah we'll just click the each yeah so which
screen that's what we looking for all righty okay now we're good now we're
good thank you thanks for catching that um so anyway the picture on the right is obviously the same telescope same person
uh and and actually the same house that I grew up in um taken in 2016 so um a
little bit more flab on the belly but other than that the telescope's still the same I'm a former Air Force a70 fighter
pilot and t38 instructor pilot I was a former former manager on the Air Force space shuttle program back in the
1980s U senior manager at a large Aerospace company and I retired in
2007 and we purchased our land here in Oracle in 2004 we moved to Oracle in
2009 and I have my own small astronomical Observatory uh about 120
feet from where I'm sitting right now yeah and you kind of skipped over a really incredible book called The Mighty
etx oh yeah said yes indeed as Scott mentioned I'm I'm
somewhat famous uh for starting a website back in 1996 that is actually
still going uh wezner mighty etx website to kind of highlight the capabilities of
the me etx line of telescopes um and I still have all those telescopes too and
I was the chair of the Oracle Dark Skies committee uh in from 2014 to 2018 we'll
talk a little bit more about that in a bit so what is light pollution just really quick we'll talk about that
well so this picture is a recently Declassified satellite photograph showing the United States 500,000 years
ago and as you can see or not see there's no lights coming up from United
States unfortunately a more recently Declassified is that right
what it's recently disass declass recently Declassified satell 500,000 AG
I won't tell you the source okay um anyway here we go so um here's obviously
what the United States looks like now with go of light pollution not good subtle difference there a bit of a
difference so light pollution is basically any lighting that's aimed horizontally or it's aimed upward
they're typically unshielded lights so the bulbs are visible they're brighter than they need to be they illuminate
with a daytime color temperature and or they shine Beyond where and when they're needed so there's
ways to obviously address all those concerns some other terms that are used
to describe such lighting are oh why there we go light nuisance and light trespass that's when your
neighbor's lights or your business light across the street is shining into your house or into your backyard where you
want to do your Imaging or you're out there just as a you know wanting to enjoy the night
sky with your your children so so light nuisance and light trespass are a couple of terms that get applied to that
artificial light at night is basically uh covering any sort of lighting at night eliminating eliminating light
pollution does not mean no light that's kind of a common misconception by the
general public we do not mean no light what we mean is boy my keys aren't
working here here we go it does mean to be smart when using outdoor lighting like L pollution certainly
impacts the science of astronomy as us as amateur astronomers we know it too well uh there's appreciating the night
sky by the general public who know that night sky is worth appreciating and there's you know thousands of years of
cultural heritage all surrounding what's visible in the night sky astronomy is an
important business here in Arizona these numbers are from I think 2007 not
adjusted for inflation but it's still a big business here in Arizona know 300 ion dollar a year and two billion
dollars worth of facilities and so we do want to protect the night skies here certainly here in
Arizona but there's many serious issues and costly impacts from this pervasive
light pollution that go well beyond just science human health Wildlife impacts energy costs and waste and of course
climate change this was something that I came up with uh just a a few months ago from
watching some commercials on the Phoenix TV stations we've all heard that you know spending money on Space research
sending you know people up into space that's all money that could be better spent here on Earth for example feeding
the homeless and the needy commun families well there's there's a here we
go there's a company up in um organization up in Phoenix called and
they do this summer of a million meals uh and they claim that they can turn $1
into five meals h so light pollution energy costs are $7 billion annually in
the United States alone so that's 35 billion meals that
could be provided to the homeless and needy every year if our governments and businesses and citizens would just stop
wasting life that's a lot of meals that's a lot of meals if you add in healthc care cost of all the ailments
that are caused or contributed to by light pollution that number of meals increases even more and of course
worldwide this adds up to hundreds of billions of meals annually so if you tell people that you know some of them
may not care about all the health issues the various cancers blood pressure problem Parkinson par because it's not
affecting them but they say yeah we're wasting all this money on Space research you tell them about billions of meals
are being sent up into space that might get their attention yeah so uh the
international dark sky Association which is headquartered down in Tucson about an hour from where I am
uh promotes this win-win solutions that allow people to appreciate the dark Starfield Skies while enjoying the
benefits of responsible outdoor lighting the international dark sky places conservation program recognizes and
promotes excellent stewardship of the night sky they have several categories of De
designations there's communities there's Parks reserves sanctuaries and urban night sky places these designation cover
places of different sizes of different types of uh Recreation different types
of preservation activities that they do each designation has its own set of guidelines which are available at
darksky.org idsp and you can see the cover of the dark sky Park program guidelines and
there's right now as of today there are 180 places designated worldwide uh since
2001 and they expect that they're probably going to hit 200 here very
quickly oral state Park was designated as the first International dark sky Park
to be an Ida International dark sky Park in 2014 and here you can see the gate sign
that we proudly hung the international dark sky Park sign underneath that and as Scott said it's going to be
the site of the 2022 David H Levy Arizona dark sky star party and astrophotography workshops so we're
really thrilled about that up here in Oracle so welcome to Oracle State Park
this is one of the signs that will greet you up by the parking lot and you notice there that the international dark sky
Park is highlighted there right in the center orgle State Park's a 4,000 acre
Wildlife Refuge here in the northern foothills of the Catalina mountains just north of
Tucson the park offers dayuse picnic areas and over 15 miles of trails that
are used by hikers mountain bikers and equestrians and it's no one very famous
for those Trails a section of the Arizona Trail actually crosses through this through the
park there is a remote area that's available for stargazers when the park is closed uh and I was out there uh
couple of weeks ago doing some Sky quality readings for Scott and sure enough there were like three cars
sitting out there looking up in the night sky people looking up in the night sky so here's a kind of a scenic view of
the from the park showing those mountains about 100 miles to the east of the park the gerero mountains and this
is where those the fires were that I mentioned earlier the fires were out there in the
mountains one of the neat things they do at the park uh is they do live music events and they will place musicians
that you see right there in the center of the picture along the trails and as people are hiking the trails they will hear music as they go along and then
when they get back to the main complex the ranch house and the parking lot area shortly after said we've got telescope
set up them for our star parties very very popular type of
events so you know Scott uh was mentioning about the zodiacal light as I
call it or zodiacal light as other people call it to me it's the Zodiac so
it must be zodiacal light anyway um so here was a picture at the park during
one of our star parties and right here you can see the cone of the zodiacal light coming up in the West e sky and
this was Venus I think up in the sky at that time um so yes indeed you know we do have nice Dark Skies here at Oracle
State Park and because you can see the zodiacal light this next picture was
actually taken just outside of my Observatory here with and I'm about four miles west of orgal state park so you
know the sky quality is still pretty much the same and I'm showing genen shine and that's this little bright area
right here in the middle here's the Andromeda Galaxy the double
cluster pleed and the Hades so just a nice night
sky rendition but gig and shine very visible from this location shows you
just how dark our skies can be here so I hope to see many of you at Oracle state park for the Arizona dark
sky star party next September uh we're gonna like Scott said we're gonna have some really great speakers and you're
gonna have a really great time at a nice dark sky location so contacts International dark
sky Association at darksky.org Oral state parks at Arizona State or aate
parks.com Oracle and my Observatory copia at weiser.com
so over back to you Scott got any questions all right thank you so much Mike that's great um uh we have uh we're
going to do a 10-minute break here um and so uh um uh you know grab a sandwich or a cup
of coffee or whatever you'd like stretch your legs and uh we'll be back with uh
more astronomers uh uh coming back with Tyler Bowman Jerry Hubble Annie
Scarboro uh all from uh explore scientific and here in Arkansas uh
marchelo souo will be in from Brazil um and um and then we've got our contingent
from uh Argentina so stay tuned the argentinan
yes excellent presentation Mike uh hopefully my uh so my image of
the uh clouds with light pollution under them versus clouds at a dark sky
sight um I found that interesting I had taken
the picture of the clouds cuz I was trying to shoot at the Milky Way there and then the clouds just showed up right
at the time I got set up so in frustration I just snapped a photo
little did I know that I would be uh that photo would then be useful for I
guess showing some differences between what a dark sky looks like and a uh in a
you know a sky that's not far from City portal 4 versus portal one right right
um and now I'm intrigued you're you're running around similar time frame to the
uh Oki techar party and now I'm torn because I'd like to visit Arizona and
see Dr David Levy who uh Maxi and Molly you all missed out we're all honorary
doctorates thanks to uh Dr ly he handed them all out to everybody that was uh
here for the early part um here's the ironic here's the irony my wife is a
real doctorate she got her Doctorate in Education uh this past year I think uh I'm
supposed to know the date but you know remembering things is not my strong
point but um it took her quite some time a number of years to finally
get oops uh oh uh oh he got
phras but now now you all have frozen so oh he's Frozen again but he's in a cool
posst he's in a cool like yeah seems to be on your
end yeah my internet connection is unstable it says it so I think everybody
has internet issues really today yeah when I woke up this morning um I found
out that I had absolutely no internet connectivity uh from any of the ethernet
connected devices or the Wi-Fi connected device I actually what we have here because
it's a rural area there's no cable TV there's no fiber um it used to be on
huget up through you know through a satellite but a year excuse me a year ago we switched over to using an LTE
router from AT&T and the cell tower is about a mile outside my window so we have good strong
signal I get up this morning there's no nothing on the network but the phone still had 5G and LTE so rebooted the
router and fortunately it all came back but I don't know what happened but
because it had never just totally died before in fact I couldn't even talk to the router um from my computer through
Ethernet just because the lights are still all blinking on it but absolutely no he used the power button to try to
turn it off but not turn off that can all be caused by a squirrel that decides
to chew through the line or Ray that hit the right bit and flipped it yeah I think the squirrel's
probably more likely the cosmic ray is cooler though we have had some more
solar activity so that might we might get one of those that would be that
would be fun to watch or not if chaos were to ensue but yeah yeah we at least
we would know what's going on what I was saying before my internet rudely interrupted me is that you were trying
to get your PhD weren't you Molly aren't you you're pursuing it now right yeah so
you won't need any stinking honorary doctorate from Dr Levy you'll have your
very own we we should get certificates you know from from Dr Ley I mean he's a
real doctor so yeah yeah I do honary you know PhD certificate signed by Dr David
H Ley I'll I'll ask him to get right on that um I'll be sure to show that to my
advisor yeah you're already an honorary doctor yeah are you sure need to keep taking this class I
mean you could try speaking of honorary doctors uh Dr Maxie is in the building
how are you doing well I'm not actually a doctor neither am I but we I guess I
have to carry on um bestowing the honorary doctor except except Molly
you're trying to get a real one so I can't you know can't shortcut your process Tyler you get one Annie gets
one I think we are selo doctors yeah Soo is PR previously to say
fake so mostly uh well I'm I'm I'm I'm so sold
tonight because I came back from home from my work and my head was
really heavy yeah I take a no no no I
take a i profan to okay I I I felt like
I have some kind of fever so okay I I take a shower I go a little to bedroom
but I didn't know if I'm going to connect but I say now I have to connect because I my mind has to continue and
what if I feel bad again I'm going to bed again
but uh you know I saw a picture from from a person from paray that yesterday
took pictures of the quartet of Gru the four galaxies and it's passing by right
now A a comment call it calling let me
let me find it the name is h leard no no no L we can see it yes
from here it's the cool picture Molly wow is the 190 P Borelli it's
passing by really near through the galaxies and I don't know if what no
it's really yeah it's not coming up for a while too much shine but I said I
thought oh this is a really good opportunity because because I have it here in my over my head but I'm really
tired I and also my wife took off the the computer I could do anything so okay
maybe next time it will be happening again sometime so well you gotta take care of yourself that's right Maxi you
gotta you got to take it easy on yourself it's it you know I understand
you are needing a diversion you know so you're not thinking about how maybe bad you feel but also you have to take care
of yourself so you feel better yeah yeah so I I
really you know when I remember when I spent time outside in my backyard in
Winter I and I was focused taking pictures and and and see how is going
the The Guiding and everything and I forgot that I have to care about the
freezing but and also I I didn't eat I didn't drink any water and I've done
that yeah and when I realized I said I said now okay let's take a break now and then
when I take a break my body is say really shut down and well H it's very
difficult to to carry on but uh it's also it's all for the
pictures for science that's yeah new
there's go ahead Molly on the topic of Arizona one of my friends and I we just
purchased nine acres outside of Tucson nice we're really excited oh yeah
nice the the how far outside of Tucson about an hour and a half East uh near
the town of Willcox oh okay I know where it is sure that's that's almost to the border with New Mexico yeah yeah it's
I've heard the border is a pretty dark area yeah it's on the other side of the mountains from Portal Arizona okay and
uh the skies are are bort to it's like 20 um was it like uh I think the sky the
sky magnitude was like 2197 or something like that very very dark 219 is bort one
I thought anything above 21 I think it's I think it's 22 is is the I have to go check but yeah
it's you're you're probably border 1.5 yeah yeah we're we're just yeah it's it's
it's probably darker than Texas Star Party because we're not gonna have all the oil rigs in the area I can guarantee
you it is yeah so we're really excited we're gonna first a campsite um but
eventually we want to build a remote Observatory out there yeah well we're all coming just so
you know we're gonna hold one of these star parties from Mol what are you GNA call it you've got uh
we haven't named it yet yeah Molly some you've got as Molly so we're going to
Something in that's going to be in here AST Molly Branch or
[Music] something
that was a beautiful sonification it's really cool
wow yeah I heard it a lot a couple days ago that NASA published yeah I thought I
saw it too I I don't think I heard the sound though so speaking about the Dark Skies
I didn't mention it but we're here in Oracle on a good night with not a lot of junk in the air uh we're 215 plus so
yeah that's well anything 21 Milky Way shows
up the sun is the Twilight hasn't ended yet and the Milky Way is pretty bright y
so that's I see that it's time to get the camera out and spend the spend the
night seeing what I can get yeah I'm extremely extremely excited about it so we're we're we're gonna try and go out
there in February and uh do some camping and kind of get the lay of the land so
um awesome yeah I'll be I'll be I'll bringing bring my some of my gear with me so I'll be sure to take some good
pictures looking forward to it well Scott I can show this image of the Pelican nebula real quick yeah why don't
you why don't you and then we'll need to drop off everybody so take care Mike
thanks for having me thank you mik appreciate coming he said Mike see
you yeah so I I transitioned my main telescope the 8 inch Schmid Crain there
over from that quazar to tonight's main Imaging program which starts with the
Pelican nebula so this is the Pelican nebula in hydrogen Alpha and those you can see the antenna that I was kind of
talking about and I guess you can really kind of see one there there's there's a couple there's another one or two um and
this is just this is a single 10 minute exposure I I'm not doing live stacking here this is just a single frame as it
comes down 10 minutes yeah wow yeah it's uh so yeah it's a lot of
hydrogen there um it's just off the east coast of the North American nebula so
kind of in that same complex up in signis it is um about let's
see uh gonna see how far away it was oh 2,000 light years away and is 30 Lighty
years in diameter like this is a nebula that is like 60 times larger than the
solar system um at least depending on how you measure the width of the solar system and uh yeah and and it's just so
much really cool detail that's been blown out by shap shaped by the Stellar Winds of stars that are in that area
right very nice very cool very cool yeah oh I came see live images
coming down and it's something you did point out to Molly that um you know
uh about looking really really far away I mean billions of light years and
recording data that is something that's within the realm of amateur astronomy
and uh you know so to think that your backyard telescope can capture that light and uh you know and you can you
can stretch your your equipment and your mind and your understanding uh you know
to those kinds of distances is just it's utterly amazing we are living in the Golden Age of astronomy I say it over
and over but this is it yeah and and when I was looking up some information
on some of the quazars I was hoping to go observe uh tonight um one of them
it's currently more along the lines of probably magnitude 17 but it had a sudden brightening to magnitude 12 back
in 2016 oh and it faded over the following couple of years so I didn't get to dig
into what they thought caused that but imagine a galaxy from our dis from it's
like that one was like eight billion light years away I think brightening to like brightening by five
magnitudes man like what kind of physic happening in there you know right so I
yeah I want to go read up more on that um but yeah 12 12th magnitude is certainly within the range of of being
able to see it visually and it was probably caught by an amateur you know because we're Imaging these things all
the time it's like huh that's a lot brighter than than the last time I imaged this sure um sure so yeah there's
there's stuff H even in even in ancient distant galaxies there's stuff changing all the
time uh TK uh watching on YouTube was interested to know what scope and Camera
you're using scope camera and filter that you're using for this image yeah so this image is my the telescope is my 8
Schmid cast grain from Celestron I'm using an f6.3 focal reducer so it's got
an effective focal length of 1,280 millimeters this is with the zwo
ASI 1600 mm Pro Camera so the 1600 uh
monochrome camera from zwo and this is the optal along 3 nanometer hydrogen
Offa filter that I'm currently borrowing from opong excellent okay well up next is Tyler
Bowman Tyler uh is the host of focus on astrophotography um uh he is uh one of
the senior tech people at explore scientific he's involved in product development he's involved in uh QA he's
involved in many things in our company but uh we're very lucky to have him uh
and um uh he is uh here with us tonight from his home Observatory Tyler it's all
yours man Scott I guess I got a promotion I didn't even realize it g
me um want to I want to I want to thank everybody that was able to show up um
Adrien Molly Mike Kareem um of course David Levy I wish Jerry would have been
here because I know he had a great presentation to do but a little bit about me Scott basically said it in a
nutshell I help customers get started um that's that's what I do for Explorer
scientific and I am Imaging tonight um but I kind of wanted to go over some basics of Dos and do Nots and Molly's
going to hate me because I'm Imaging a Target that she's wanting to image so we'll get to see that here in a little
bit um behind me I don't know if you'll be able to see it very well is myos 100
now I use this as my portable setup now portable everybody wants it to be
lightweight and easy to assemble and that's what this is for I have the the
2inch tripod legs which you can't see I'm aware of um and I can carry this
around in a backpack it's holding the um ascar f ma230 I believe which is 230
millimeters of focal length with a reducer which is a 50 millimeter lens at the top here I also have a guide scope
of the zwo F430 mm with the ASI 120 Mini
on top is sitting the ASI air plus um which is the newest um raspberry party
that zwo came out with with a Wi-Fi antenna but I wanted to see if it was able to do
fullframe um I'm using the zwo 6200 along with the opal along set full
opal along set of I believe the hydrogen Alpha 6.5 um lrgb and I believe the O2 and the
or the O3 and the S2 are 75s believe or may be reverse
anyway but some dos and don'ts when setting up telescopes that I've learned
over the years and also what you do and do not do when you're messing with monochrome
cameras some things that I've learned the past week with monochrome cameras is do not change filters and swapping them
in and out with different sets don't do it you're creating more problems than
you want to um you're going to involve or get more dust Moes on everything and
you're just going to ruin your whole night's image the flats will not be able to calibrate correctly um for the lights
because of you swapping your filters in and out um but with mounts standpoint you
always starting out is want to make sure your tripod's level the reason why you want to make sure your tripod's level is
just to make sure that you are going to get good balance and you're going to get good polar alignment because if your tripod is off just a little bit or out
of balance or out a kilter with the ground level it's not going to get good tracking and then you'll want to
obviously polar align with the the Polaris or the NCP with your current
latitude that you're using there's softwares that are out there I'll go over those here in a second um the ASI
air does it that has a polar alignment feature sharp cap does it which is free
I think it's 15 for the year or 18 for the year and they have their own um they
they just came out with plate solve you're able to take pictures it's great for planetary uh it is uh it does polar
alignment it does Focus assistant it it literally does everything that you need um if you want to go the cheaper route
excuse me and you also want to make sure that when you polar align or when you
balance is I balance in the central axis some people balance East heavy some
people balance West heavy I balance dead Central um I find better results that
way in my opinion I don't I'm I'm taking away variables that I would possibly
introduce to the system but again everybody has their own thing I'm not
judging you for it it's just what I like to do um recently um I've had back
surgery the P I think it was eight weeks ago and I I hang on I got forgot you got
a screen share I keep forgetting this screen share we're going to do the screen here that way you can see
everything this is my backyard now I know we've talked a little bit about light pollution um you
can see some constellations you can almost see the Big Dipper coming down but this way is north to Springdale of
where we're located you can see a giant light Dome this thing is huge from where
I'm at in my backyard um my bort scale is believe a six and a seven give or
take um but I all I can see I can see the NCP for Polaris from where I'm at
and that's all I need to see because I have my Pier set right here in the
backyard which is six or 30 inches deep at 16 inches around some might some
people might think that is overkill it is for here because our frost line I believe is just 12 in
so yes I went Way Beyond the frostline but I wanted to make sure I wasn't going to move and it's sitting the there's an
ioptron cem60 sitting on top of it with um the explore scientific FPL 53 140 and
on top of that is an eagle which is it's kind of like a Nook computer with the guide scope sitting on
top um right now I'm Imaging currently the heart nebula can everybody see that
I can't tell yes we can see it y Molly I'm sorry for
a while I somehow had Molly spotlighted while eating her dinner and you
explaining your presentation there but yes we can see the uh the heart nebula
there it's very cool so this that one's coming up for me later this evening it's it's the second target I'm doing tonight
correct yeah don't worry okay so I'm I'm currently Imaging with the the es40
um I got the 2600 monochrome with the an I believe the name is
antila uh Pro filters um this is obviously a 900 second shot of just ha
right now I plan on doing a full Sho palette on it
and I'm believe I'm getting only yeah I'm going to take 45 and hopefully make
40 I'm G to then do 03 next which it's not going to be tonight it'll probably
be later in the week because this is taking forever I didn't realize how long
900 seconds was and then I did the math I was like oh my lord it's 15 minutes a single sub so I'm G to be out here for a
while um guiding wise the reason I went with the pier is because I'm able to get
02 on the pier awesome now you can you can get this
anywhere as long as you're able to get I'm going to circle back to a level
tripod a good polar alignment and good balance this is what you can achieve any
mount with with this particular Mount the isos 100 I'm able to get
04 on the the total r or the ra
oscillat so it's it's easy to achieve with a $400 Mount Adrian you can achieve
amazing amazing guide uh not I mean some people like to use the little Sky
guiders uh they're great they help they definitely get you into the
hobby but if you want to up your game up to something that's a little bit still portable and it's not overly heavy this
would be my next bet it really would it's it's still within the same price range as a ioptron sky guider the star
Adventurer yeah on skywat I have it's all they're in the same price realm but
you get a little bit bigger of a payload back here and it it's the ASI a is very
it configures very easily you can literally and you can use an iPad um for
it you can use a SGP for it and it's it's easily configurable and that's the
reason why I love the portability of that particular Mount um because the one out there it does not move it's it stays
I have a trip here if I ever decide to take it off I'm probably ever going to because I like the way the guiding is
going so that that's why I like that one back there because I can literally throw it in the backpack and I can take off
with it that's why I love it I really do one thing one thing I would have to start doing is um turning my images into
composits unless there's a like a half cederal tracking mode because I use that
all the time to take single shots of a uh you know of a scene I go 30 seconds
yeah and you know you kind of It kind of balances The Best of Both Worlds thing but I do have an image that I did where
I I was able to get two minutes somehow it was early on with that uh guid
unguided I had two minutes of a fairly faint Milky Way that I was able to then
you know brighten up and then I just did two minutes of the lake in front of it and managed to stitch them together that
is the one image that showed me yeah you can do composits I think a lot of the
Top Guns in the nightscape business do composits more than they do single 30
second shots just because of the they can turn a bort four Milky Way into looking almost like bort one because
then they can track it and then they can lay in the uh image um underneath it so
so that is something I did start looking at that and I will probably be getting a hold of you uh soon we have specials
going on right now with Black Friday I'm telling you man now's the the time to do it well I to do a sales pitch but now's
the time to honestly do it it really is I'll be yeah I'll be getting a hold of you and those and those that are watching the um the live stream here
will probably get a hold of you as well and if I do get it I will and if there's
one any left Adrian we promise to get you one yeah I appreciate adri yep I it it that may be
coming soon so I'll I'll go back on mute and turn it back over to you all but uh
definitely interested thanks Adrian okay all right so up next is um uh uh Jerry
Hubble had to duck out uh for the night so uh we'll go straight over to Annie
Scarboro hey everybody I'm gonna talk talk a little bit about um Imaging with or uh doing
astronomy with uh your family um I currently right now
um I I currently right now um have a I I have four children um I have three older
three older adult children but um I have a four-year-old that um when I started
working in explore scientific I started noticing some things about him he was very interested in the moon we would be
driving during the daytime and he would say hey Mommy the Moon the Moon you know and I'd think I can't even see it and so
but then I would be turn around you know turn my car around to go another Direction and see it and it was it it
sparked something in me that um made me realize that um he is seeing things in
the sky um and he's starting to recognize those things so um I I decided
to go ahead and take the opportunity uh to try to start teaching him some things whenever um Tyler pretty much Tyler and
Scott and everybody at work pretty much uh made me take a telescope home
right so okay we we kind of just jumped into this talk here to give you a little bit of background you're not familiar
with Annie Annie is um she uh helps manage the explore Alliance she does all
the membership services and and she make sure that uh you know that members are
getting all their benefits in addition to that Annie is a customer service representative she is
learning astrophotography her background is photography she so she has a a good
background in in photography similar to my background I started off as a photographer then got into astronomy and
stuff so uh but uh every day she's up to her elbows and up to her neck and um uh
all things astronomical and equipment and solving problems and stuff so and
she and I have talked quite a bit about her family and the excitement that they've had and getting involved with
that since now Mom works at a telescope manufacturing company so yeah there you
go thank you I'm sorry Scott I'm see I'm really new
to all so um yeah so when I started at explore scientific I had never touched
his telescope I didn't know I I honestly never even thought about
touching a telescope so um I had a lot to learn and um boy it really sounded
like U Charlie Brown's mom when people started talk at customer service so I was like am I ever going to learn this
stuff but um I've learned quite a lot and I know there's still more to it and so um but um it's been really neat to
watch my son's name is Daxton it's really been neat to watch him um spark that that interest to spark in him and
so when I first brought home a telescope which was our FL uh 10 10 102 100000
it's a 102 it's it's 102 with a a th000 millimeter focal length and so um we
brought that home we brought that home and um or I well I brought it home and
he saw it and I got it out one day and I said hey Bubby no he said he on the way home he wanted to see the moon I said
hey Bubby you want to see the Moon up close and he said yes yeah I do and so
um that was his first time ever seeing the Moon up close and he just ever since then anytime time he's with me and he
sees the moon in the sky he's like I want to see the moon and so of course like any mom I go home and drag my
telescope out and get it all set up for him and so um we went from that F that
102 we lost your voice there
Annie I thought it was my internet for a second she froze up you know today has
just been a crazy day for the internet uh 6 millim it wasn't it wasn't very big
at all um and so you know you never can tell with the child like if they're actually seeing stuff because you you
know at four years old they're like yeah I'm looking through it and their eye is actually closed and so um I I learned
really quickly um I asked Tyler I wanted a bigger eyepiece to bring home and so he gave me a 62 degree um eyepiece and I
brought that home and I immediately realized that the reflection that was going through the telescope through the
eyepiece was then reflecting on his face and I was able to tell if he was actually viewing something because he
would stay farther away from the eyepiece so that's that's that's one major trick that I that I've that I use
with him as a little guy to be able to see if he's actually viewing things um
and so and then now we've gotten into etiquette etiquette with um telescopes
about not grabbing them staying you know when you when I when he climbs the uh little step stool to keep his hands
behind his back and to not touch anything so that way that's not all over the place but um I wanted to show y'all
some pictures of him viewing um let me see if I can try
to and and how quickly is is your son Dax I mean absorbing astronomy I mean
you're you would you know what is that like um he is um he is can you see that
yeah okay so this is him the first time viewing with that FL r102 um he is really really quickly so
um he let's see um we moved to the ed80 and then one time we were out we were
out way out in the middle of nowhere I can't remember the name of the town we were out in Arkansas but we came out of
this building there was nothing else around except for this this bu this huge building and um we got out into the
field where we were parked at and I said hey Dax look up and he's like oh my gosh
I can see space so he's you know he and now he asks to see stars when we're
looking at stuff he'll he'll point out things in the sky that he wants me to turn the telescope to um and so um this
is him this is this is our house I have a really small house I live in Prairie Grove I think Arkansas I think my I
think I'm at a bort three where I'm at um but he um he photo that's great um this
is him you can see the reflection in his eye um this was actually taken at night
it of course an iPhone loves to do the whole little dark Imaging thing but um
this was taken at night um he you can see the reflection on his on his left eye but his right eye is open and so um
you know because of that I'm able to tell him hey you know move this way or
you know I'm able to get him more lined up with it because we're using that bigger eye piece um and then this is him
learning e the etiquette of of standing at a telescope um to not touch it or grab it and so that way it's not moved
and um it's staying lined up to whatever you're pointed at um obviously we have quite a bit of um street lights and
stuff around but he's still able to see things um he's still able to see things
and point them out and so um he you know he's real quick um we just came back
from we just traveled to South Carolina and we're driving you know out in the middle of nowhere and he um I I just
rolled down the window and I said hey Bub look out the window and he's just like oh my goodness there's so many
stars you know and so he's he's absorbing it quickly and it's kind of funny I feel like at times I can't I
can't keep up I feel like he's learning faster because I want him to be able to see more and planets and things like
that and so um I'm not learning as quickly as he probably could but he's soaking it up I mean absolutely soaking
it out he has a Galileo scope now um that he asked to get out all the time um
you know this year I'm for Christmas he's going to get some binoculars and in his own telescope I mean he knows he
took a little mini telescope to school to his daycare to show that off I mean he he he is soaking it up and he's
loving every minute of it so wonderful I love those images great um yeah we look forward to
him doing a presentation here soon because we have kids that up yeah we
have young ones that just love the night sky and have gone into it I I I am so I
I I am eager to one day to take him to a dark a dark site so he can actually view
what what the true sky is like without any light pollution and so um I think I
think it'll be an amazing experience not just not just for him but for me because I've never seen one either but um but it
you know if you place that stuff in front of them and um they're just like little sponges they'll soak it up and
they'll learn and and it's it's it's seeing past what's right in front of
them even though even though he's four he knows that up you know he knows that
there's more to our planet than just our planet like he knows that that space he knows that there's other things out
there and so and it's really neat to watch him um you know get excited about
that and and really interested in it so that's very good because you yeah
it's something that can be grasped even as a four-year-old that we're not alone
as long as that's how we're presenting it um save our save our planet by
showing that it's not the only thing in existence and maybe there could be some good to come out of that
so job Mommy thank you Adrian you know and that makes me think about there was
um one day we were talking because we'll talk about stuff in the sky and one day we were talking about the moon and I
there was a planet I can't remember which one it was that was near it and I
and I told him because of course I got out my Star Rocker app because I'm still learning so and I told him what it was
and he just was floored he's like oh my goodness that's you know whatever Saturn
Jupiter whatever been it would have been Venus and then it would have been Jupiter before the eclipse Venus was
near Crescent and then it was a little bigger and Jupiter was near it so yeah I
mean for him yeah here yeah one of those but at four for him to understand oh
that's another that's another plan you know it's a planet it's not a star I was just he was he and he and he would tell
everybody for a week you know couple weeks I saw such and such you know and so he just he really loves it he really
loves it so I'm excited to see him learn so so great yeah wonderful okay all
right so um well so does Annie get a raise now for for uh showing family the
stars in the night sky trying taking out of your paycheck
okay I have to ask my employer no I think I think it's
wonderful you know when when we have um when we have people that work at the
company uh get involved in uh astronomy and they don't just see it as a job but
they see they see what's U you know what is happening uh uh you know with our
community with uh the um seeing the journey that they're on and the and the
uh you know their their Explorations their their personal discoveries uh and you know see that
carry over to um uh people at work whe they're taking telescopes home and
enjoying it and sharing that with their friends and family and stuff uh that that goes beyond um that
goes beyond uh you know just uh the money and the um um you know and just
the mechanics of running a business you know so uh you know I guess I could have been selling washing machines and
probably making a lot more money doing it um but uh I find uh selling
telescopes and uh devices that you can explore and make uh discoveries with far
more interesting and rewarding you know so I'm glad I'm involved in this business and uh and Annie and Tyler and
Jerry for that matter all are very um they they get it and they're they're
into it and so uh that's great and uh you know we hope Annie is with us for a
long time and uh and she as we grow she'll grow too so well that's well and
that's the great thing about explore scientific we're not I mean you you know you're talking about selling telescopes
but I always tell our always tell our customer members we are we are 100%
about um educating and making sure you you are successful in your hobby we're not we're not just about you know our
products so we want to we we want to encourage people learn and and grow in that and that's what I'm trying to
instill in my son and so um you know I want him to grow and learn in that you
know not just sit behind a a an electronic device so right yeah
excellent you all are you all are making me wish I lived in Arkansas sign me up get me an
application we wish you did I want to work for explore scientific now but I'm
in Michigan I don't know how that's going to work out but uh it's just a plane flight away so you know okay
that's right well I'll keep that in mind all right so up next is marello Dr
marchelo Souza um he is uh running the uh young stars of Tomorrow program uh
but marchello is uh uh trained as a cosmologist he is um uh professor of
astronomy he is an icon of educational Outreach in uh in throughout Latin
America um and he's been involved with UNESCO he's been involved with so many
programs uh he's helped young people reach for the stars uh uh not not only
through their uh regular educational programs but through star parties through special events through uh having
kids build Cube SATs um the list goes on and on uh but um uh you know uh Mar is a
a a great friend he is the editor co-editor of uh skyup magazine uh Global
astronomy magazine and um marchella is with us tonight so marchella how's it
going hi nice to meet you nice to meet to all of you it's a great pleasure
thank you for your kind words yeah it's all true hope I I I haven't done it justice really because uh you you are an
amazing uh individual and uh we're all Lucky those of us who know you personally are very very lucky to know
you and uh the students that are affected by you are you know their lives
are changed thank you I hope so I hope but
we have many many students that are very motivated now with the projects that we
have develop and this make not only me but our of our group very happy for some
way we are doing something that can change the lives of these students yes
it's quite I I we talked earlier about the we are concerned here about the
participation of human here in Brazil most of the girls in science and then I
I have now I make a short search and I have data from braz about the
participation of woman then we can see our problem here and the
of scientist like Dr that is a Brazilian that work at n import to motivate the
students I will share here this great then you see what is the problem
here in Brazil because you're having now many many woman in
universities uh you can see here the presentation yes yeah we see your presentation okay
thank you thank you here here is the woman with University
degrees for AG from 25 to
34 20 5% of the woman have University
degree and the man's 201 16 in Brazil this information from
Brazil from 35 to 44 24 this this data
is from 2019 before the pandemic H from 35 to 44
you have 24% of woman that has have University
degree and 70% of men from 45 to 54 we also have more
woman with University degrees here in Brazil 19
% of the all woman with the 45 to 54 age
you have 19% of the woman Withers degree and man 30
13% and from 55 to 64 we have 15% of
human and 13% of men then this appears
that to having more woman here Brazil with University degrees but when we look
I show us what is changing this is what Chang in the in the
Years this is the percentage in relation to the total number of higher education
professors now in 2019 46 almost
47% ER of the professors University are women
nearly half that's great yes almost half but when we look for the participation
inam careers we have this we have most of the woman are in social sciences
Social Services pedagogy and when we look for care
careers like engineering Computing technology we have most of
them are men I have here the percentage you have it in in
Computing you have only 1% of human from the total we
have almost 87% are men that work with Computing
engineering we have 22 that are women that work with
engineering and the physics chemistry and we have almost 8% that are men then
our problem here to motivate woman to study science to study
engineering then this is importance of Dr hos Lopez and the other Brazilian
scientists to motivate the students the girl in the schools this is this is our problem here
in Brazil is a problem worldwide really you know
um uh there are advances in in various countries but I think in general um that
uh this this story is repeated again and again you know um and uh so it's uh I
think it's it's our duty to encourage young girls and women uh to you know
get involved in science and engineering but it is necessary and
important to do this and I hope that in the next years we have more students
that are girls here in universi in high schools now I have we are working now
developing project that we have visit these schools then we just after the pandemic
period here in Brazil because the schools opened in August private schools
and the public schools only opened in October here in Brazil then we began the
project almost in the beginning of when the students arrived again in schools
after almost two years in without participating any activity in schools
then I will show now the pictures here in schools that we have visited I I I
only shows few image but we already visited 13 schools and we have contact with more
than 200 students and most of them are girls wow yes I I believe that what's
happening because the the boys they needed to work because we also have
economic problems here in Brazil then when this happens most of the boys young
now they begin to work to help their families then most of the students in
school now are women brail girl here are
some pictures that we took and we visited
schools you can see here I have 15 students in this class and nine of the
students are your there something that is changing here in Brazil but I don't know the
reason I believe that the reason is because St the the boys need to work ear
because of the economic problems but we have all the schools
that we have used in different seats is the same thing that we
see here you see two this is is making us very happy two girls that received
the prize for the best project about astronomy oh that's great we are given
prizes in every school for the best projects then two girls and we have two
students now here that participate in our group Isabel here is responsible for
the programming to teach programming for the students okay and kolini ER is helping is presenting
about the developing project with the student to develop animations
cartoons with the student Arts so so marello do do you think that
with um uh initiatives like uh young astronomers for tomorrow you know uh do
you think that we will be seeing a lot more women involved in as professional
scientists and professional uh Engineers uh in this
generation yes I believe so on here Isabel here he she
participate in the activity now she is not with the church she has a church that say that cold is
foror then she talks every every day that you have activi she say same thing
for the the girls because they can participate in in programming engineering what they want
to do that's great is what to we try to show to them and we are inviting also
scientists to talk with them you already participate in one of the meetings with
the students and we believe now that any can help to
motivate the students in the region where we live here in Brazil [Music]
in North Region of Jan State and we are also developing a public activities even
with the pandemic because we are finishing the I believe so now that it's
finish here Brazil the period because we have more than 70% of the Brazilian population
now are vaccinated then we are trying to return
the activities and we did uh two Sundays ago the Saturday and Sunday
we done with driving for astronomy here now we have a sub production I don't
know if I can say this but we have characters there was a a big
program for kids about astronomy is it is a driving about astronomy only about
astronomy we have telescopes to show the live of the Moon the SAT juper and the Venus
we show live this is not the first time marchello's done this Drive-In uh event
this is held at a mall uh you drive your car in like you're going to a drive-in
movie theater okay and uh and they show these astronomy programs which is just
fantastic yeah I have a video here that shows what's happened this time okay I
don't know if you you can hear the sound but I I'll take let me see if it's
possible to transmit the sound
here only music here here is the entr of the driving we have more than 40 cars
participate in each in each session the is the biggest uh Shopping Center
off seats you have telescopes and have a lot of cars there yeah and I have these
characters let's participate the people participate from their
cars and what a wonderful way to do you know something with safely in this
pandemic you know people and this show here amazes I think that's not supposed to
see the sound but it is many have kids with t-shirts about
astronomy that participate it's a big success here in
Brazil yeah oh that's wonderful that is
wonderful I don't think this is being done anywhere else in the world Marcello this is this is
fantastic this was a great experience for us and we we received invitation to
do more sessions of the driving and probably we having new experience but
this was a separate production because of the shopping they have the characters of they have music is about astronomy
then involve the kids was a special project for kids for the participation
of kids right we have a we we did six
sections the in this last experience that we had
here that's wonderful if there are Oscars to hand out for people who do astronomy Outreach marello you you would
certainly get one you know thank you it's fantastic uh now earlier marchella
also talked about Dr Rosalie Lopez from the Jeet propulsion laboratory and NASA
will be giving a presentation uh earlier tomorrow um to uh your students and what will she
be covering what will she talk about marchello about he her experience ah yes
and she have the we choose the best students that participate in project in
the schools yes and these students will be in the same home with her to talk
with her live then fantastic I'm sure they're very excited it's it's it's wonderful
too that Rosalie uh Lopez um gives so much of herself you know and her time to
to do these things of course she is also from Brazil uh that's that's her native
country um and she's been working in the United States as a scientist for a long
time if you don't know who uh Dr rosaly Lopez is you can look her up on
Wikipedia But to my understanding she is the world's greatest discoverer of Volcan knows in our solar system and uh
uh so she is a a world-renowned planetary scientist um and uh a huge
inspiration tomorrow at 4:00 Central Rosalie will be on the explore Alliance
uh uh program uh talking to Nicole Ola
she's an 8-year-old uh research astronomer she has been called the world's youngest astronomer and and uh
so uh Rosalie will be uh translating uh
Nicole's story uh for us and I think it'll be fantastic and so I'm looking forward to that um that whole program
overall soell thank you thanks for sharing your Drive-In experiences the
latest things going on with young astronomers of tomorrow and um uh you
know and also explaining uh some of the challenges of uh of women in science in
your country uh but I think everywhere that um people should encourage uh you
know half of the population of our planet uh to uh you know to find the
ways to express themselves through science through engineering uh through technology jobs
um because uh uh there's many brilliant women in the world that uh in years in
decades past of course um uh did not were not given the opportunities and uh
so there's a lot of work still to do uh it's better but much much more work still to do so um thank you very much
marello it's pleasure thank you um up next is uh
Nico uh Nicholas Aras uh hammer time with Nico
uh Nico is in Argentina uh he is uh someone that startled all of us as
amateur astronomers as he showed us stunning astrophotography done with his
dobsonian telescope uh with no Motors no computers no electronics uh just a
camera attached to his dobsonian while he guided it by hand so um he continues
to do that kind of work now and uh are you with us hello how are you Scott hi
everyone yes come on okay
Wella well we have a a a really nice show tonight a beautiful presentations
and the topic uh tonight is the Look Back Time and I think that uh we we
several times er end up talking about the this about the the distance about
the time and the the machines that we have as my D here I'm here in in my
patio in the Astro patio and and the the
look back time is is something that always wanders me because I I observe
and I start just looking up and thinking about okay that happens a long time ago and
prob probably is not there now or maybe change or whatever and as you know I
used to I I love to to make all with my Dobson I have an aqual Mount but I love
the the the Dobson moments and so tonight I will show you uh some
live live images with my live images your do Sony
yes awesome and about the that the time
I I love the double Stars so I will start with a double star in ranus that
is called P idani that is a double star that both
stars is there are about 25 or 26 live
years distance so uh let me share my
screen okay are you see yes yep
okay well let me find my way with my hands
obviously and uh there it is the double star and these two stars is an an
orbital double star and the the orbit uh is
around have it here you can see this is the the the
partial orbit with the all the observations the historic observations
from 1825 to to now and the the period
is about a four 493
100 years so as they are at 25 like years maybe
well no maybe it's is an actually that we are looking how in what position do
those Stars was in the orbit 25 years ago so uh as you can see we have we have
here the historical separations in in 1825 it was a 2.5 Arc seconds and now
there are about uh 11 or seconds so the they are cursing the the
orbit this way from the down to the left and now they are
probably here there maybe at 10 arcc
separation so that is it's really it really makes me think well I
observe or capture that yes we are looking really the past is is amazing
and these stars are only 25 light years ago and now we will
jump to a a really known Global cluster that I show you a few GSP ago that is 47
toan in in toana let me go
there
Nigo yes the seven of December we have to go to Alber again yes and there we
have the 47 toan and now we are looking like
16,000 like years so this
the not not not only that we are looking to the one of the
older stars of the Galaxy but we are looking
16,000 years in the past so this is really is really
shocking and there are there is another glob cluster really close here that is is
Inc 362 I I think if if I'm not wrong
let me find here
we it's really un nicing without the
motors it's a contract to ring work let me find that the the shine of the screen
is flashing me
okay I can't believe that you don't use motor
it's incredible really yeah there it is it's really
entertaining and this glob Blaster is about 27,000 like years distance so we are
much on the past is is really it's really shocking to think
about this and I I I used to go out with my DB and start observing and then I
found myself like 20 minutes just looking up and thinking about
this so well this this was a a short presentation but I I I love to to share
and talk about this so okay thank you everyone thank Scot I
hope you enjoy this I did I did I I love watching the um the style of astronomy
that you do uh your explanations um you know I love that you
dive into uh uh you know some of the scientific explanations of the objects
that we're looking at so you are you're you're a sky interpreter of the best
kind and um uh you know to show us that you can do this with uh uh large
aperture telescope that is very simple I think would make John doson himself very
happy to see what you're doing so I I think so and and he and John Dobson did
was not one uh who enjoyed astrophotography but I think that you might have been able to um you know
Inspire him he probably would have wanted to try it himself yeah that's wonderful it's
really nice and and it's like to to encourage everyone uh that yeah maybe
has no come on a big scope or a big Mount
yes isn't cheap so if you can start with ad option you can observe but if you
have a camera or a webcam you can do a lot of things so that's right do that
yes that's right that's right and just do it that's right that's that's that is
uh um you know a uh a very important thing uh that all amateur astronomers
should do they should try things even if people say oh no that's not the best thing to do or that's not the optimum
thing to do don't don't let that stop you because you might just make uh if
you're out there get getting data and doing astronomy you might just make a discovery okay no that's far more
important than maybe getting the the the sharpest possible image of a star so of
course of I I told you in in a GSP that I I measure double stars and I discover
a double star with my Dobson so everyone can do that yeah it's wonderful it's
wonderful thank you Scott thank you Nico that's great okay uh do we have Caesar
with us I think he's there hi Scott how are
you how are you I am in blue color here I don't know why you are in blue color
Yes fine Scott how are you from your home today I am home today that's the studio to your home right yeah yeah
that's right yeah it's it's great maybe you can enjoy the show in your home
because it's it's I don't know if you are if you are near to your home from the factory but I'm pretty close yes I
am really I'm pretty close but uh today we did not have internet in our offices
is a rare problem but uh apparently a number of us on our program tonight had
had various internet problems so I don't know if it's something going on around the country or around the world but um
but we're here and and it's all working so that's good yes excellent and uh here at
tonight tonight I I'm returned to the balcony and it's just a it's a great
great night um uh talking about the look back
uh about time in uh from from the space from the the the really huge distance
that we are talking about time I chose for tonight um tarantula nebula and
tarantula nebula when we think in nebula uh we think that they are normally in
our galaxy and they are uh at maybe uh
15,000 years like years um but I choose
uh this nebula first of all because it's between two buildings and I can took the
a pictures lights for for tonight for for processing and the another in the
another way is that it's really uh very
far away um this time for a nebula because tarantula is not in our
Milky we if not is in our um that we call it accessory galaxies that
is large maganus maganus cloud and it's
um such While most of nebulas for
example I think that that is at
15,00 years old or or um nebulas are from
three, years old like uh I don't know I
remember if it's M 27
maybe the closest and this is incredible because uh I I
today nebula it's it
close the same distance that oreon nebula uh we can see shadow of the light
in another scale it's the is
um you know maybe if you think uh for United States you think
that you are your Galaxy is New York New Jersey is um a large Magan cloud and
this nebula it's in New Jersey it's not in your city it's a it's in in the in
the neighborhoods it's in the in the Suburban areas and this is incredible uh
because the the scale the huge scale and talking about how was the H the the our
planet uh and when the light starting to that today we receive starting to to go
from the nebula we are talking about the time of the [Music]
first n time n
n sorry the you the the first home um
the first apparitions of religious religious uh things in in in for the
first uh the first uh humans the because
uh it is the the starting uh of the sense of
Consciousness um uh when uh archaeologist founded from
this age the first signs of religion cons you know that is the the idea of a
God or okay why because they started to to found the bones the the the bodies to
the bones of the body together with the sense and in the first in the first time
of our idea of cons of con when humans become an age of
reasoning or something yes absolutely and
absolutely yes I can show you now because I I I I couldn't uh process the image
because I have the the the image now very green sorry but maybe you can see
let me share the screen sorry sharing screen is a problem
in our show every time okay screen of the show yes you
know yes yes it's normal that if not it's not Global Ser party if if
you if you share the screen perfectly in the first it's not the global star party
yeah you're not watching the global star party yes
yes that's right yes sorry Scott no no problem no
problem there is the ne Cesar and there and plus you have blue internet today
you have a blue internet so I I don't know yes Blue tonight
yes yeah absolutely yes abolutely
underwater I don't know but is
um Let me let me know if you can see the
neula here hi
[Music] Mo Cameron Gillis
says blue screen NE the huge F because this is in the
area I think he has some issues with the
connection but he left us the the image so there are the there is the nebula and
there are a lot of nebulas and clusters there the core of that nebula is amazing
also watching with with your dobsonian and obviously taking pictures is kind of
of BL M you know yes it's amazing and and this is a NE in another galaxy so
it's it's mindblowing yeah I see that's very cool that's very cool let's see if
Mar let's see if Caesar comes back if not we'll go to Maxi and then I I imagine Caesar will come back but um
give him a couple of minutes you know it's really cool that that uh you three guys come on almost every Global Star
Party um you know I I always look forward to uh uh the Argentina part part
of our of our program you know so uh I we go I've been
thinking about a show that you guys can do uh that's really just uh for South
America you know so um so if you guys might be you can talk about that but if
you're interested uh I would be interested you know so we have some spots open now U uh Dr uh Dr bar Daniel
bar is uh ran his last show um uh and he
he he had our Monday SWAT uh so Mondays are now uh opening up if if that's
something you guys would like to try to do on a weekly basis or you know or if
Global star part is where you guys like to be then that's that's I'm pleased with that for sure
so oh that that would that would be nice it's SC we can do it yeah I know I I
know you guys can put together a great program so any any excuse is good to us
to to share and to laugh and also to to to meet again you know H we we met a
really good friendship ER of course we have some distance between us well Cesar
and Nico there more maybe I don't know maybe an hour but here I I'm really outside of
Buenos I'm some kind of F and when we met like we did a couple
weeks ago uh you know with the pandemic situation and everything we we we we
have a really good time chatting laughing telling jokes and also doing
astronomy and and and that's um you know of course
the astronomy really join us but that's how you well I'm here talking
to you Scott you're are from United States and I never thought that I was
talking with you a couple years ago and I I never talk in English alive on only
once I translate some a tourist in Mar Plata in my
holidays I remember because he wants to buy a t-shirt churchs and that's all but
here I'm here with all of you ER chatting laughing and sharing astronomy
of the kind of way that everyone ER can do and that's really
inspiring yeah we love it too because you know
you're you're sharing with uh you know amateur astronomers all over the world
and um uh you know they're excited uh to know what um astronomers are doing
down there in the southern hemisphere you know because it's it's a place we all long to be um uh you have uh the
greatest skies in in in the world and uh um you know and so it's we can we can
explode that you know we can H well last
GSP ER when it was I I don't remember his name but it was this person from New
Zealand and he took pictures of er of the Aurora australi and you know Theo
it's more down like New Zealand it's a little more down further south than
where you are and I I I I didn't saw any
picture of if anybody of that place took but you know I don't know if they they
know if if they are allowed to sell that
but I think because of their latitude it's more to the South they're may be
going to see it more that Aurora but I think that is it's not that normal as
the but yes we need to to go to for to take
pictures yeah call and well well you want Nico a couple of months ago I was
there a few month ago yeah in traveling with my with my
family we have Cesar back is he back yes yeah yes team team Argentina it's always
a pleasure to be on with you three right through the direct W know why I didn't
invite people from Chile and we do um yeah but um so far not not a lot lot of you know
participation is intermittent but uh um but uh and then Harold mentioned that
there are Chile astronomers on YouTube all the time so uh they're out there for
sure so yeah they'll be here back yeah Cesar
is back great don't spy the neighborhood yes but was was completely
was completely uh um sh down the the internet um this was because I don't
know how how was that but I I was completely out
connection um well ER as uh we are talking tonight h i i trying to to share
let me I don't know if oh I I well here
I can show you something that is the the process of guiding with the exos
100 tonight exist two things here one of this is I move and the graphics um show
that I move but the graphics when you don't have movements are for an small
Mount ER rly align polar aligner uh you
have two seconds of of movement and that is
really great uh when I move because my my floor here in the balcon is is a a
wood deck and all connected if I yes here if I move here you can see three or
four seconds movements but really were great and existed a little of wind of
course uh if I go to the balcony the winds appear uh it's something that the
wind follow me in my life um and um another thing that I can I can
show you let me see if uh if I can I can share another
picture uh well the the things that that
um that is that I need to I need to to
process a little uh maybe before maxi before sorry after Maxi I can show you
something uh processed but very very fast processing uh to to watch something
more than the blue or green sky that I show you sh I show you because maybe for
internet of the quality of internet today is impossible to see stars I don't know because it's uh here and in my
computer I can see a lot of stars in each um light but I know that it's
really really um it's really difficult and not
easy to to show by internet because the image is really with a green background
a really strong green background and maybe you forget absolutely the the
stars that are really really are pinpoints um and the mon really
worked amazingly tonight um I need to to make
something that is a technical thing for the people normally we talk all time about backlash about the quatal month um
this month is really easy to remove the cover and make the O the the owners make
the two things to to adjust the the the
the backlash of the Moon as the owner like and this is something for me I I
prefer um a little of of backlash more
than than ER than a mount really adjusted a
lot because I prefer er something more
loose um and use the mount with a little of unbalance here yeah and were very good
but if you have a little of wind maybe H you have the graphics that you say
okay it maybe you can adjust a lot but this well you know Scott because you
manufactur the M this is only for for screw move the cover and you you can put
U the level of of of backlash with only two scroll more and another one that is
you can adjust with a coin and it's maybe you you spend five minutes to to
make your adjustment as you like and this is something that I love of this
month really um well I Maxie I give
you give me give me five minutes to to to toal put some calibrations and uh and
get the green or blue background out out yeah to show something about the
tarantula nebula but this is it's a great a great picture and maybe now it's
going to the to the beside the buing but
um but what a great what's a great uh um
Arro after photographic night in Buenos in in a
very absolutely yes I can count only three stars in the sky
now oh yeah six year only three no yes I know bfield
because is yes but not bfield that this isn't from in the south of of woid but
it's really near a I born I in my childhood I live at only 15 blocks from
the the neighborhood of NE of Nico um but actually they have a lot of lot of
lead lights in in yes H it's the same
similar is re Shin that that's why I I hide myself here in a little Pao and I
only can see the the South I don't see the east or the north but here we I have
no lights directly on my eyes so yes I I I found more more easily some Stars I
think you there with the with the buildings is really hard to to to to get
your eyes involved in the night it's really hard absolutely and it's an
advantage when you have a a patio because the patio work like a
Observatory where do you have the walls and this is very important to to know to the people some people say told me that
live in the cities and say oh okay I only I can see over my head this is
perfect for for cities or for for a life polluted areas because a a a a big a big
um uh problem a huge problem of of every cities uh it's um that you have for
example I received the the light from this window the reflection of the my
living yes now I I put it I I I I turn
on the lights of my living room to don't don't H appear so
blue but turn off the blue light and start the white light okay yeah really
of course that this is why because this is why it's a great tool a great tool
astrophotography with everything that everything that you have the uh for
people that live in suburban and City areas because it's unable to to watch
something of course that I if here I I use it I us it um 11 in telescope and
you can see the nebulas and you can see maybe and um some galaxies uh but do you
have a huge huge Dobson telescope or Smith cine or well we are waiting the
vix telescope the the 2660 Scot yes yes I'm dream with it with that
otaa yeah as soon as we get one we'll send it down maybe March or or yeah this is
starting from from Japan now the they Japan yes wow that's right I when when
you told me about this is something like when you told to the you talk about toys
to the kids for me yes your no no no I
confess yeah yes I confess that every one time at a day Scott I'll go to the
bigon web page to to because I I forget
totally vixen but when you I see you in the P say come
on come on bigon yeah we're really happy to become the new distributor for Vixen
products um I you know I might have told you guys this before but back in the 80s
I sold lots of Vixen products uh as um Celestron introduced them uh just I sold
I sold Mixon you too yeah yes by by Celestron yeah I for great you know so
why not you know so I I thought it would be a nice addition to the explore scientific line and U so uh you know
something else uh Cesar I don't know if it's possible for you but it would be wonderful if you could come up to the
Northeast astronomy Forum uh this April and uh I hope they have lots of Vixen
product April 19 April 20 22 next year
next next year yeah next year in April okay I don't know yeah yeah yeah but uh
um definitely have you in our booth if uh you are if you're able to when in
April when when in April uh I will tell you here in a moment
[Applause] okay I'm calling to my wife Evangelina yeah
maybe something happen yeah things
happens that's right uh it is here I'll
share the website also with um the called NE Expo and uh this is the 31st
annual event and it is going to be April 9th and 10th n and 10 okay one week nth and
10 New York okay New York yeah great so you fly into
New York City um you know if you're if you if you come then you'll be I'll make
you part of our team and uh and then you can you know uh we'll make sure that you
get settled in so absolutely we don't have problems to make planes absolutely
no three seats Cesar yes know I
I have to get my passport first it's a business it's a business trip for me no
problem yeah absolutely it's a business trip yeah yes it's really great what maxia I
I live no no problem we are I think because I need time to to I need time to
five minutes to to yes to stack something to show
something more uh to see some something because I I Tred but share with you the
the nebula but I think that you told me that you see something like the Sea Under the Sea or nothing I don't know
it's more like in the lake of Baro something like that very
very blue okay okay I think you're going to get some data okay okay
sorry Maxi before you start I I I I would say goodbye because I need to take my child on bed so yeah no problem man
guys have a great night see you next week cheers that's
awesome thank you Nico take care see you man bye bye bye or maybe next Global St party SC no
problem we can we can uh stop here no like you you tell us no problem and I I
can process much better and we can talk about the the nebula it's it's all up to
you it's all up to you so no problem yeah I think that it's better okay all
right sounds good all right so I guess we're we're
going to Maxi at this point right okay yeah well I well thanks again
for inviting me and good night everyone I'm Maxi feres from CH
Argentina and what I want to share with you is kind of what I did of course we
had some partial Luna Eclipse last weekend h i remember I it was a really
good Thursday came back from the gym and I well also came back from the work from
my work and start to to to put my equipment in my backyard but also what I
did is went outside from my city going to a a rural road from dust Road and I'm
trying to to see this eclipse and make some pictures with my dclr camera but
also I was a controlling remot ER remote
controlling the the mount from that place here in my in my backround my
backyard and well H let me share my screen uh let me
see okay do you do you see it
yes okay well this is a a little selfie that I sent
some we see thumnail images right now I don't see oh sorry sorry sorry
my I have to share everything right there
so there yes well this is not Dar Vader
this is me ER and here behind me is obviously the moon I have a little Mount
this a and Sky Watcher and and you know
I I didn't know if I I want to to go
outside of the city because it was very late it's maybe kind of dangerous of of
the insecurity and everything H and also I was really really tired and it was almost 2 a.m.
that I have my another equipment outside I Was preparing and pointing to the Moon
I focus and everything but I said now I think I no I'm going not and then I said no man you
got to to go because there's maybe one of in a lifetime so I say okay ER I get
my my my equipment my little equipment went to my car and drive almost 15
kilomet H from here okay you know when I was traveling I saw this big birs I
don't know how you call it in English we call buos or
lusas and there was really big they they they hunt a mouses at night and there
was really bigs and they old sorry ah thank you and and you know I I
went to this part of the of farm area that is in the in the entry of a farm
that I don't know who it is the owner but there there was nothing there and I
started to to put my equipment it was almost 2 and a half a.m. and the clips
is going to start at three point um three am. and minutes something
like that so when I was H searching and taking
pictures h of my another equipment with the with the8 inches and and controlling
remotely I was taking pictures of this of of course this is processed stacked
and processive before the clips started because I want what I want to do is a
time lapse with this equipment and also with the dclr and then I'm more later I
will show you some videos that I did H well this case ER it was
really really detailed besides of the bright in Moon
and well here's a a snapshot or screenshot
that I did of my cell phone you can see here is the for G
connection the battery but I was connected to my notebook outside of my
backyard and I'm 15 kilometers a outside and I only was
doing a pictures well in really really fast pictures uh taking uh 10 frames
only maybe per minute and then I I want
what I want to do is stack them and process every every stack to get more
details [Music] and sorry this is a a single picture of
the dclr you can see all the field of view that I have I use um a t objective
is a 17 er no see no 17 no um no yes 17 millimet
um and 2,000 mm of FAL
length put it on the start adventure uh well this is almost at the
at the Sunrise is going to get D but it was like I said it was a
partial eclipse and you can see almost the circle of the
shadow on the moon but the brightest place it was
amazing here's another picture but is a
crop that I did you can see a little well it's a huge bird but at the distance it looks like a little and
also the the moon going down to to the Horizon you know H here I I watch it
almostly Complete because I have free Horizon but in my home I only have a at
least 12 degrees of altitude so er well you know when the moon goes
out I start to see this Sunrise it was really really
beautiful H because this kind of picture reminds me some pictures from a sun set
of Africa something like that you know but there's uh the the Pampas Farm is very plain area
it's beautiful very nice andet wow this is another one you know I
I put out my camera from the the mountain and I start to to shoot it like a machine gun and well you know um this
was almost H six ER well five and no and
45 minutes am or maybe almost 6 because I know at
6: a I came to my home and then at the almost 8 of that morning I have to go to
work I I was like a zombie but I have to go it's my
responsibility but I spent all night wake
up it was a huge sacrifice yes well but you you know maxi that we are um what we
are talking or by by at the same time because of course that I was totally
sure that Maxi was um was wake up taking
pictures of the eclipse and I I send of course that I send
a text message by WhatsApp and from your talk yeah from your
rooftop well this is great well I I I I sent you to Scott the pictures um I I
remember that you you was uh a wake up too Scott and
yes this is incredible yeah well this is from with my eight
Ines and this is the most ER picture that I could took before the
the building start to to pass in by so it was was like I say a partial but
you can still see the the Shadow and the the the pink area uh well of course this
is dated and well H here's a a a video that I did of
[Music] um of the eclipse with the 8 inches with
a time doing the a time lapse you I started now
ah wow here we go beautiful and Co and that was the
last one and let's go again you can see the details and I and I start to see the
the penumbra but with my eyes in the farm
area it doesn't see it you know but ER I
when the the the the the shadow starts to to get over the the
moon I felt like I was in the solar eclipse because the brightness started
to [Music] go down and you know I I remember I can
saw ER really far away because I I was my
eyes well accustom rated to the dark and the mon was a really good reflector but
when the clips starts go on it was like
mostly difficult to see more Beyond maybe 10 Mets and when they the start to
go really dark at the East you start to see this the the the glowing of the sun
coming up it was really very good good
experience well this is a time lapse ER with the
dclr you can see this more a better view feel of
view and so the exposures are compensating I guess that's the reason
why we see some yeah some I I was practicing cool that is cool it's right
yeah at the end in this place when the sun well stat go goes rise up
ER the the this this part of the you can start to to see how it still continues
and then almost disappear it's not horizontal with the field because I
forgot a part of the mount and I have to put it really ER in clean it
so well this is a a selfie that I
took here's the the moon happy happy Eclipse photographer
absolutely yeah yeah and also the mosquitoes oh my God annoying you know
at the da it started to go to to to come again but here's another one and here's
sply this is something that for us or for people from Texas maybe that is
normal we we for for us is normal that we have all time the horizont and we
have this landscape without nothing and maybe you drive three four six hour to
see nothing any m i remember the first time that I I know the mountains yeah
this is something that is crazy because I remember that I never could imagine a
mountain and for me this was incredible because it was an experience uh because
the first time that I went to Cordova that is in this in the middle of the country I think that I was 14 years old
and for me was totally amazed by the mountain because we
we flat area see exactly seen yes it was
like that for me in Texas too I was born in Texas raised at various times of my
life in Texas and yeah there's uh the PLS of Texas are flat I mean really yeah
yes I can imagine the the the same but for me I remember that was I was with
the with the school to the to the first trip to the to the mountain yes small
Mountain because I that happened too when I went to tandil for
holidays to M Plata you had to to passing by the the national route and
you passing by through this what we call we don't call mountains because
there the same in United States yeah and you know you are also
in or yes and when you are passing by this ER mountains that they are more
like meeta because at the top they are flats also they're not it's the same the
Patagonia where you have yes yes the same well you you saw you see all these
rocks and everything and and I and not when you go maybe 100
kilometers outside you start to see again the flat area H but this
these are the the Pampa is all flat
practically absolutely when is Santa Fe we are talking about the The
Province the province that we call to States provincias uh but it's the same idea and
they are not so big like states in United States but you know that Argentina is it's comparably is big uh
um we have a lot of provinces where you don't have mountains this is it's
incredible um um and do you have provinces that have
only mountains yeah uh yes well I have I have
something to show of the of the neula if you like uh
to to see something Scot if sure I I can have have ready this yes well let me let
me share it's
alive you can see the the registering in a live live okay yes 50 or or 50 okay
this is the magic when you are cing something and you put out you get from
the open wow you can see with with good
resolution the the string yes but I think remember that the the
processor it's well it's working and you're sharing and no yes but this with this
computer you don't have problem because we use um I use uh solid dis for that
computer and it's really fast but maybe you know the problem of this is
that uh that um is that I use it now for
to to make something er something fast to show something to
the audience it's h that I choose the first likes that I took in the in the
first time of the of the night um only 50 50 liks of 15 seconds each at
800 H is er ISO um well we are waiting the magic you
know but maybe maybe uh I I produce a a entire uh uh
short uh shortcut of electricity in the entire city I don't
know I am whaiting this um please
work please work yeah yeah if you stuck in pcks inside you have to maybe no to
sleep St no absolutely but I have a lot of
like of two or three minutes uh while we are talking um I I I'll
use I'll be using this the another one the two or three minutes a guided
pictures uh to stack in tomorrow now this is only to show something
because I like to go to sleep happy to to have something I you know
I when when I ER start to do astrophotography I remember when I put
my equipment inside I have to S what I
took and I have to process and then I'm going to bed maybe 8 a.m. and then I'm
going to work is the same illusion absolutely it's the same illusion that
you had in your childhood when you went to to the
laboratory to the laboratory to to get your
pictures um it's really great I well I don't
know here I I I give give it a time give it time yeah yes let me see maybe I can
one in 40 I don't know well okay stacking the the the one in 40 I don't
know is it six maybe four maybe this is for the
next Global surar SC I don't know
well only you no yeah no I when I when I was last
weekend outside you thinking I'm feeling the magic I feel
it yeah you you can you can hear the the
drums and on part that magic called patience you know so that's
right it's frustrating when when the stack doesn't stuck good and you had to
do it again and you had to wait another couple of minutes or maybe more yeah and
well and that's how you do because when you you see that it it doesn't work you
don't do you don't say no this this is a this is um this is bad pictures or I
took a really bad picture no you have to to keep practicing the stacking because
sometimes with the dark ER frames with the the oh the flat frames ER you can
maybe get a better picture and or a a better stack imag
and you have to give it time and still practicing in this case yes something
that that I remember now about this illusion to to to spend to to White
something is that maybe one time we we talk with uh Scott um about uh the time
when we make a photography with films and we went to the to the photo house to
to developing our film you know Maxi maybe you remember in your child in your
childhood maybe you you remember something of the 24 and
30 six uh pictures frames
um I don't remember films we we call it I think it has maybe
what yes remembers in the history books they have
yeah was a craziness because we we spent maybe we had one decent pictures by by
completely film or maybe you normally I remember that that we um we choose
something that we call it contacts to to have yeah you would get a they they cop
yeah all your negatives would be on it absolutely and then you can pick out which picture you wanted from the
contact sheet yeah yes a completely green pictures like the first maxi the
same that that you you watch like the the same picture that I showed you today
you had the the great picture the greatest picture was uh with very very
green color in the background you choose that and you return to the
laboratory for me like I studed in Optics we had um laboratory in our
school I had the darts the the a German copy ER we call
it copiadora was a a a dart um head with
with the the same system you remember maybe Scott the the the brand from Germany d d
d u t I think that
is J JS yes and they have a copy master
and I remember I think in reverse the colors to to to to re the same the same
that we make today with the cues Maxi we make in laboratory H with a system of filters in
the head of the machine where we Chang the the the
colors to to yeah they were dials where you could you could your color and H and
and yeah yes let me sh one
yes if I have something or not but nothing's is cool as
Photoshop yes yes no no no now picks inside no chemicals no uh sure no hazardous
waste you know so no it's too much okay yeah I think Caesar I think this
was this is gonna take a little while yeah no no yes okay for next week no
problem next week okay yeah yes yes if you want to send me when you stacked it
I I would I would like to to process it if you want you know we can compare it
but you know here in my home Austin have in in his computer pix
inside and he's a genius of PX inside he he he come how when I have likes guided
likes he said give me give me that to me give me that me to me yes yes no you
know that that that really really I I have a a a lagun nebula
picture that process Austine I say with the same telescope I say okay bye-bye I
go to sleep and Austin
continuing taking pictures and 100 ISO really 100 ISO I don't know how he used
very low viso really all time I I think because well when you do I figured out
when well in this case I am do using a ah a deep Sky camera H the the gain
that is recommended for this camera is a 100 it's practically the same of 100 and
yes you know when you see the the soft frames er only without stretching
you almost see the the the the stars and everything but when you st and you
process and do the AO stretch it's a lot of information that you get and well ER
you don't try you you try to not burn
the stars because you want colored stars and if you go more H gain maybe will be
will get H White ER yes yes absolutely Maxi it's
something that I I um I don't like um I I think that I think I see that my my
son don't like is make a lot of colors and if for example Austine I
remember that that what in his presentation H he uh he told that okay
here is okay the nebula was really with a very clear background and he told uh to the rest of
global Ser say for me it's okay because this picture was toen from the city if I
start to to put a darker background I lost a lot of information and this is if
I go with the same telescope to the to the to chil Koy for example I have more
more information uh I can get a a a darker uh background but um make a more
natural background from the city is is a great because you have um you have the
things like really are yeah it's it's the same for for for
is the saying that you when you make an over color picture or you know I can see
every time with you you you invite me the fourth of December but of course I
invite you with the this the 7th of December is well well you I think you
you told me that you going to work the next day but of course you were invited because I want to go ahead to iberti and
and I'm trying to do some pictures maybe the global party together from yeah I
was talking with Marcos and he says to me that ER maybe about the internet in in
this place in yes because the the mayor of alberty is going to put H some
security camps and you know in that area is passing by it's passing by um f
Optica fire Optics fire Optics yes and they can get a really good connection
but I don't I didn't talk these days but in a few a couple days is going to put
these cameras and it it will has internet connection H you know maybe we
can do some live view but I I'm I want to do pictures I
I I well I only did this Eclipse lunar
Clips but I I I think that you need you need yes you need uh because you are
told me yes send me the pictures to process I'm really I'm really hungry to
to take pictures yes yes I I know this this feeling I know for me was the first
day that I CH I I changed the the 80 mm refractor instead the the maxut of 127
that was amazing I have my telescope in in the living room because I here for
me it's it's great have two different OTAs Optical Tu assemblies uh a
refractor and the the the the maxut is there are two
different telescope okay well for me it's
okay for me too I think Scot yes it's
it's all yours it's all yeah thank you now really thank you every well okay so
let's let's kind of recap what what uh what happened tonight we had um uh we
started off the global Star Party of course with David Levy uh and then uh we had Chuck Allen
from the astronomical League join us and uh you know he related to us that he was
a a surprise I did not know that uh he was working on a book about a surfer and
uh you know and this you know and the surfer's life and everything which he's
trying to finish up which is really cool Kareem Jaffer uh you know from John Abbott College he's a professor of
astronomy there and very involved with the Royal Astronomical Society of Montreal Center was on with us uh
talking about Look Back Time and uh you know the effect of all of that us as
amateur astronomers uh trying to uh describe almost the Indescribable I mean
trying to give people a grasp of the distant Scale of the Universe and
really just how far away we're talking about these things we talk in terms of light years and Parx and mega parex and
uh you know the numbers that range these huge numbers that you have to put it in
in a couple words in a c words right and often often we're talking to people who
don't think in these terms they don't think in numbers this large you know and and uh so it's it it it offers a special
challenge for amateur astronomers who do educational Outreach uh to be The
Interpreter of something that's pretty complex pretty hard to to wrap your head
around but to make it simple and digestible and relatable somehow what
what I do I do the example for the Sun the eight minutes from the lights that's come from the the the surface to get us
and then I start to do some little math at the talking with the people saying
well you have um 3,000 kilometers per second I think that's how it calls the
in English the lights of the speed and you have in one second that's speed and
then you have in one second in one minute 60 seconds so you multiply then
you have a one hour then you have 24 hours and then you have
35 and 60 30 no
365 days that you multiply that yes and you have one light year one Lighty year
and then you multiply for example of four to Proxima Cent or
alent right yeah and then though the the is
going to many that's right and we're not even out of the Milky Way yet right I mean we
we're to the closest star near us in the Milky Way and so and also what what I
say of course this case an well in this time
is behind of the sun almost but I what I was telling the to the people is you are
seeing a star that that light is coming right now from us it came out maybe when
Columbus came to America yeah right at that time it's original these are
original photons they're not copies of photons they're not reflections of a photon they're unique it's it's the it's
the photon Crush made inside that star flying across space all this time
and we're catching it in our eyes you know yes it for me
connection today when I choose when I choose tarantula nebula and I started to to to
read again you know when you you chose something to talk and say okay I forget
I forget the scale that this nebula is it's at it's completely different for a
nebula 170 miles sorry
170 thousand like years and when I I
went to the I have a story of the science is isak Asimo book in my my uh
in my my biot my biotech and um I I choose
uh in in in the first be before the history before uh the history do you
have only the the parion of the ner tal like something of the scale and you are
you are done talking about far away galaxies if not the local your accessory
Galaxy that is your is your neighborhood it's not the Glo it's not the the Glo
the the cluster uh local cluster galaxies no no no it's is
completely uh your neighborhood and say come on this it's ridiculous it's
something that is completely mindblowing and uh something that say come on I I
can and also I love to to watch the expression of when the people really get
it yeah and that's a light a light is coming on
in their mind yeah yes and they say really yes really it's like that it's
like this and yes whoa they they they get shocked that's right absolutely is a
a kind of Enlightenment you know that they have for a moment and it's at that
moment too if they start to ask questions you can tell that they're really for maybe the first time in a
very very long time they're really exploring you know they're really exploring because they're out there
you've taken them to an unknown Place yeah understanding these vast distances
maybe for the first time and uh and now that they are they want to know more and
uh that's a really important time for anyone at any age because you are
starting to you know that that's a moment of real learning you know and uh
so astronomers have have a special privilege uh when they're when they're
doing this kind of educational Outreach um uh you know to experience
this with other people that's the reason why I love educate doing astronomy
Outreach it's it is um yeah it's almost a selfish thing because I get so much
energy from it you know when I see I see when they get it you know I'm like okay
okay you know right but it's not something they when they go home
afterwards their mind is actually really changed you know still processing yeah
they're still synapsis still happening in their mind
still chewing gum that that fall and that well and
yeah people are their fun their minds are different now because you know they
understand oh wow that that this is going on and if you if you um uh you
know add in that they are connected interconnected to the universe you know
not separated no not separated because part of the universe too you know and they
also they realize or or what I want to to to make
them realize how lucky we are and in this
fast of universe yes and also maybe you
feel really tiny but but sometimes you you start to H to
think of a lot of problems of our lives and also I have my problems you have
your problems and that's that's the life but
you start to do step by step and start to think that now yes it's a problem but
I have to slow down because to the universe the universe your problem is
yeah nothing exactly maybe a photon is bigger than that problem
so yeah yes just it's a great and when you wake up you see these people wake up
a little bit to this and they realize oh what somebody said to me is not really
important okay and uh and then when they think about maybe even the life cycle of
a star or the life of a you know know of a Celestial system or something like
that they realize how short their lives are are our lives to a star is like you
know if it if it if a star could somehow understand how long its life is it
wouldn't feel like it's long but it would look at our life as like a spark you know
yeah only a blink of your eye a blink yes well here I have the nebula is
not a perfect but maybe okay let's see yeah you
know no no it's horrible but you know it's horrible come on the horrible nebula huh
you taking pictures almost 10 no yes but impossible to make something here
but but no um because I touching I touching the the
only with div skyer that and and it is very bad to to regulate the the the
contrast and the and the level of colors it has to be but yeah but of course that
H it's it's really easy to to make uh uh
something maybe if I don't know
maybe no it's it's almost ER save them and yes I save in in in
taranta and and we can see you see in Photoshop ah
okay okay I don't know where
is no yes 1M 1 a.m come on
yes oh my God uh here where is yes H Magness
and so Cameron says you need to add the flats yeah yes yes this was only a a a
experiment yes you know Scott what how I do my flats
images I with that with a t- shirt white tshirt or no this is great people are
doing outside when the sun start rising up they point to the clear area and
start to take pictures but when I did it with this camera I I I have my my pictures
really annoying really noising and and I
did like I still did at before H I only
pointing to my rooftop it's white okay my flashlight that I you saw on
your on your head yeah and pointed the telescope and see the the parameters and
start to take pictures and that's it that's your Flats yeah that's my flats
really cheap Flats but but work very well
exactly yes very cool I I was really get me crazy because I was for
the NGC 300 Galaxy I took almost five hours of pictures and Okay maybe the
night wasn't good it was two nights difference but when I stuck with those
Flats it really changed a lot really a lot
and of course I have light pollution and that's why I want to go to Alberti
because I want to do all night that Galaxy yeah but you
know it it really get shocked and I say okay this flat works okay I'm still
doing inside my house when when I
finish right well it's okay ah yeah yeah yes
you have a lot of all those eight2 many yeah yes I think
that if I make the same but but in the good way I have a lot of information to
to make a great picture no but you already have a lot of information it was
15 seconds only yeah this one only 50
yes this is not this is only 50 H at eight ER 800 800 um
sorry no no no 800 ISO ISO 800 uh 15 second and
50 50 likes 50 likes of 15 seconds each
ah and that's in the yeah yeah it's okay yeah it's good it's
good yeah maybe I can get a little less of
blue no
okay I think you have a goodal to work with I think so it's only now to to show
to to to see the the area where you have the different color of the
stars but for unguided uh pictures it's it's great I think that it's gray yes it
it's for me it's good it's a good picture me too yes it's so only only a a
raw that is the head that's the head of a grizzly bear looking yeah look
[Laughter] that yes all right remember you are in buis
in b n and you're doing these pictures pointing to the South yeah that's no yes
of course hug that's right buing and another one
you have a lot of FL pollution the reflection of the of the wall of the welding the the and the moon also right
now yes yes for example I don't know one of my neighborhoods that my neighbors
that you see that turn on a light very bright why I don't know you don't need
that but maybe look that yeah
why turn the light off please come on I don't know why well this is in the in
the countryside um we have a um for for the entire
family we have a um um in a you know in satelli uh
satellit cities of wenos ciris do you have different country clubs um we have
a house uh from uh from the family of Evangelina my wife um normally we went
uh to the to the um to the night and many many times
I took pictures from the sky in in this well I don't know why the people love
put their reflectors to the to the to the night to the to illuminate uh
trees and don't turn don't turn off the lights in the entire light in the entire
night horrible well here I have my my two houses behind me there's a person
that has a a a a a poll a a a parish
barbecue place and it you know that he puts three LS light like this one above
another one and when maybe 8:00 p.m. or 900 p.m. they they
turns on and my my backyard is completely
white that is called light trespass and uh yeah yeah you should be able to call
the your the local authorities or the police and say this guy is uh I will get
a I can't sleep you know absolutely and P P made a a great work with the light
pollution in in his neighborhood yes yes but here in Argentina I think that's
impossible to make something like it you know I can say to him or say the people say no okay I can
get yes here with us aiming the light down that's okay you know it's not going
into your yard yeah yes it's okay or point it to your yard why you point it back at
himself sure yeah back s yes 10 night absolutely great
idea okay all right gentlemen well I think with that on that note we will we
will call it a night uh I want to thank everybody uh in the audience for watching uh Global Star Party number
74 um our shows as we get closer to Christmas in December um uh there
there'll be fewer of them because it's it is so busy during this time of year but uh of course we'll be back um uh
each week with more uh programming and uh and then in January we should be back
uh in full swing with shows as well um except sometimes we're going to be going
to real events we will go to the Northeast astronomy Forum we'll be going to the winter star party we have planned
uh the Arizona dark sky star party that will happen in September um we have
another another uh astronomy event in Mount Wilson California uh using the 100
inch at Mount Wilson um telescope so if you'd like to have an experience using
what was at one time the world's largest telescope uh then uh you know you'll want to join us um and uh you know so so
some of these things are coming about um but we always plan to do uh programming
so no matter where you are you can join up with us and experience astronomy and
uh learn uh new uh techniques and ask questions from astronomers from all over
the world so have a great night and uh thanks again thank you guys good night
thank you Scott good night thanks to the audience thank you yes thanks to the audience and uh Maxi and Caesar you guys
think about it because uh I would be very happy to do a um a uh show just for
uh um you know South American audience you know so if you guys are interested in doing that yes I think it would be a
lot we we can maybe program to 2022 and specials yes absolutely that's right yes
okay yeah all right take care take care guys bye
