Transcript:
7:00 p.m..Scott Roberts - Introduction
one guy who came to one of their shows and they always remembered him as a hero
7:05 p.m..David Levy – Intro and Poetry
and they played a full set plus two encores for this guy
wow that is awesome i mean musicians they need their they need their listening
7:15 p.m..Astronomical League Door Prizes - John Goss
audience they do yeah so
it's a great if you like zz top at all or or the blues oh yeah i i like them
documentary yeah it's called the little z top little that little old band from
texas i think is the name of it yep probably on uh amazon prime or something
7:25 p.m..David Eicher - Minerals and Gems
yeah or yeah yeah
really good well done as a film even you know
yeah yeah i think i gave a lecture once to no one in the audience
wendy was on a band tour and there were three people in the audience they never they never
advertised it because they forgot to advertise wendy's performance that's their loss my friend
8:10 p.m..Barbara Harris - Strange Stars
that's right yeah
i remember wendy and i visited um visited suny at cortland
8:25 p.m..Molly Wakeling
where wendy went to school we had lunch there with the president who we really liked
and he asked wendy if she was part of the large group of students that awarded
8:40 p.m..Pekka Hautala
their final exams that year after kent state
and she said oh no no i was going to teach him and i wasn't planning to avoid to avoid
any exams and the guy looked at her and said well why not
8:55 p.m..Ten Minute Break
she said i was young and stupid but
9:05 p.m..Deepti Gautam
[Music] well
9:15 p.m..Adrian Bradley
oh here comes john gloss comes on
now we have a quartet that's right
9:30 p.m..Rodrigo Zelada
hello dr john hi john [Music]
hi dave we've already been in contact today so yeah
9:45 p.m..Cesar Brollo
that smile you see on david's face is that scotty and i have given him a happiness bill
10:00 p.m..Maxi Falieres
yes well i needed one after today yeah i bet you did oh yeah
david tell david next time be careful what he asks for next time be careful what you ask for
10:15 p.m..Ten Minute Break
i i think if anything falls in on me it would be nice if it were a meteorite rather than a plane
i would think so yeah you saw your own plane crash
apparently you did not see it you didn't actually witness it no i did i didn't see it but i
we all heard it all the neighbors and myself as well um and then went out a little while
later and and their place started to swarm with sheriffs well so that that was in your town that
that happened a plane crash in our neighborhood john about two houses away
across the street a small a two-seat uh uh uh um experiment and
maybe not well i guess it is an experimental one of those two-seat kit built planes
right yeah called a what is it called i i'm not a pain expert but
but uh it's a if you want to look at you know it it's a glass air glass star
it was so it looks like uh kind of a very small cessna you know
two-thirds scale cessna two people who were squeezed in and unfortunately they did not survive
the people but it came very close to hitting a house near us so it could have been much
much worse geez yeah unbelievable
makes you appreciate what you have as wendy says yeah yeah yeah
david i have you on for a span um i had friend i i copied the last um time that
you were on where you had like a uh 45 minute span so i'll see why if i can get some
people to come on a little bit earlier especially considering the circumstance so
scott unfortunately you know me so you know i can talk as long as you want me to
but because you know me you know that you don't want me to talk as long as i could talk so
the endless droning of those who drone on endlessly yes
barbara harris is on
barbara hello barbara good evening
of everybody well we're fine today
we're all set for our um global star party
i was up all night so i just woke up from my nap oh did you
um
gotten very quiet all of a sudden yeah
it's fatigue for me yeah yeah yeah you got to feel a little
a little beat up i think
are you going to describe your events in your lecture tonight david
the events of the day today yeah no i don't i don't think so not for the
whole audience yeah it's too out there i think probably for that but
yeah there was a this is something you can't say very often but in case barbara
wonders what the hell i'm talking about there was a plane that crashed in my neighborhood today barbara believe it or
not really yeah yeah and unfortunately uh the two
people on board are deceased but it actually came in very close to a
neighbor's house and clipped a sheered the top of a tree off and so it was
could have been a it could have gone straight into this house and so at least that didn't happen but
a very very unusual strange day in the neighborhood here
when you said that i was thinking of there was one that happened yesterday
yeah san diego san diego that i think went into a neighborhood there yeah and yeah
it killed it hit the ups truck first and then crashed into the house so it killed
the ups driver but the people in the house were able to get out
gee oh boy well that was similar it sounds like but but more deadly than today's here yeah
well that should leave you a little jumpy well life is a fragile thing we need to this
this is more evidence for the value of the global star parties that we all need to get on here
[Music]
hmm
[Music]
time [Music]
hmm [Music]
[Music]
well hello everyone this is scott roberts from explore scientific and the explore alliance and welcome to the 68th
global star party um this is uh a uh
our special theme is strange universe and if you once you start learning about the
universe you start to understand as you peel back some of the layers of discovery and exploration and
findings latest findings you you start to find out the universe becomes even more strange as we go along
but it is a fantastic journey for anybody to embark on and uh
so that that is our our topic and um we will uh uh discuss that in various
ways because it can cover just about anything to do with astronomy you know
um joining us of course tonight is david levy uh david uh
david eicher we have john goss here and barbara harris we have more people joining us later in the program
um but uh i uh you know i always want to say something
special about uh david and david they are they've been uh
stalwart uh companions for most of the astronomical community for
decades now uh you know writing books uh giving lectures
uh traveling the globe uh to share what they know about astronomy and to share their passion
um you know when i when i look back on all of their accomplishments i'm
i you know i'm in awe you know my my jaw drops you know and uh you know we're so lucky to uh
have them with us tonight and uh i look forward to all the other things that they'll do in the future but
anyways we will start off with david levy who always uh
gives us uh you know some nice words and some nice poetry
some mr levy and i'm going to turn it over to you why thank you very much scott roberts
it's really a pleasure to be here and uh it's going to be
a lot of fun to excuse me
i'll try that one again it's going to be a lot of fun to to hear and see what everybody has to
say tonight and i notice in the ad you had neil tyson saying that the
universe is under no obligation to make sense to you and which kind of inspired
the quotation that i would like to read right now the first of two quotations
this one is by stephen crane and he wrote this obviously between 1871
and 1900 a man said to the universe sir i exist
however replied the universe the fact is not created in me a sense of obligation
and i think that's a pretty important thing much as i appreciate the writings of the
poet stephen crane and neil who i know very well
i disagree with it i don't think that that's true at all and we really said it it was the night
before the 2001 total eclipse of the sun
in africa and the then editor of sky and telescope lee robinson was talking about a similar
topic and he said he did not agree with that at all he said each of us is unique
and precious and of course that reminded me of that famous star trek episode balance of
terror and i think everyone here has seen that when dr mccoy says that that he's talking about the
universe and everything that's in it and in all that and perhaps more only one of each of us he's making the very
appropriate and salient point that each of us is unique which brings me to my second quotation
it's from max hermann in 1927 he wrote a poem that is now called the
sitarata and i'd like to quote from that right now go placidly amidst the noise and haste
and remember what peace there may be in silence beyond the wholesome discipline be
gentle with yourself you are a child of the universe
no less than the trees and the stars you have a right to be here
and whether or not it is clear to you no doubt the universe is unfolding as it should
be cheerful strive to be happy and now back to you scotty
very nice very nice that's great um uh
you know i i am uh i'm always amazed at how you're able to
find so many uh very appropriate quotes poetry
you know for every moment of of of the star parties that you've attended in
person and this series of global star parties that you've done uh you know it won't be long before
we're hitting 100 global star parties um but uh you know i i can imagine that
we'll never exhaust uh your ability to find just the right words to say so thank you all we're all
here in this book [Laughter] every one of them so if someone comes in
one night and steals this book we're in deep doo-doo
that's great that's great okay well um thank you uh
we will uh uh now go to uh john goss at the astronomical league uh
uh john thanks for coming on tonight and uh um
you know uh happy to uh oh as always to have the
um astronomical league uh you know attend the global star party
and uh we are um you know it's really kind of a uh an
honor uh because you know the league now in its this is the 75th year uh has just added
so much to the dimension of of uh of amateur astronomy yeah i got my actually i have my cowboy
hat right over here and i do sometimes wear it guys
especially if it rains or whatever but i got my 75th year pin right here on that side and then on the other side
i have the virtual astronomical league pin right there and
i'll add some more league pins to that hat that'll be my astronomy hat
which is uh it's great to use for covering things up and and keeping the light out of your eyes and all of that
so yeah starlight if you like pins we've got pins
you've got fans that's right that's right i think you wanted to say a few words before we got into the questions and
answers and yeah i think i have two two topics one i think i'll i'll uh dovetail in with one
of the questions you you'll see what i'm talking about in a moment but the other one on it's something i'd just like to
bring up i've been discussing this this topic with some other uh astronomical league members across the country and
they i hear coming towards the end of the year and
this tends to be more of a time for gift giving um the idea is that if you have some
small a small unused telescope an unused but usable telescope why not
put it to good use by giving it away to somebody who could benefit from it sure
be nice if clubs could have programs you know a club is is the focal point of
astronomy in the community and you know if you're in a club people are going to donate stuff to you all the
time that you really don't need um small telescopes um i will say beginner
telescopes but you know your club members aren't going to use them and so you have this
pile of equipment what what to do with it well why not fix them up and give
them away to a young person who will likely not receive a telescope
on his or her own perhaps donate it to community service organization to
your county or or parish benefit society united way i don't know
find some organization that does stuff and you can fix it up and give it away to deserving young person
i don't know that that might be the support it's a good idea uh years ago uh
you might remember mike reynolds dr mike reynolds oh yes and uh
meat instruments had eight containers of small telescopes
that were going to be just they were just going to be destroyed you know and for me
when i see a telescope if i see a telescope that's made and i i know the effort that it takes to make a telescope
uh and if it never sees starlight you know if it never gets to see
starlight i think that you know i i feel like it's it's lost
its purpose you know and uh uh it's it's a little sad to me to see a telescope go from
department store exactly to being returned and then just tossed okay
because the smallest telescope can still work the smallest toy telescope works better
than galileo's telescope did and he changed the world with his okay so uh you know the um
uh you know so i've always uh i've always kind of felt uh strongly that a
telescope should at least get to see stars at least once you know and um
so astronomy clubs can do that and the northeast astronomy uh
northeast florida astronomical society took eight containers of telescopes
was as i recall a couple of thousand telescopes something like that
and uh and with the boy scouts distributed these telescopes and they trained
everybody how to use them it's quite one thing just to give a telescope to somebody here have fun you
know it's quite another to be actually trained how to use it you know because it's that training that can really send
somebody off a long way you know it's uh without training that they might join the astronomical league or join up with
your club uh or to subscribe to astronomy magazine you know and they start this lifelong um
voyage of exploration that can start with a very humble instrument you know i often show
my little kmart telescope that i was given when i was 10 years old but you know
wow what a ride it's been you know so as you said that the smallest telescope
they they can take you on a journey to the moon and back that's right you know or you know some of the brighter planets i
think part part of the trick is is if you have a used telescope it's it's is determining how usable it really is to
make sure it's in good working order has a couple of decent eye pieces uh and always keeping in mind who this
is for you know this isn't for you who've been out under the stars with
huge dobsonians this is for a newcomer a kid who just wants to see the moon and get
started you know and it needs a spark right and needs a little bit of gear last year um
a couple years ago your friends at celestron sent me a telescope and they sent me the wrong telescope
and so i told him about that and they said well go ahead and keep it and give it away and i was thinking well you know i'm
i don't know i don't want it it was about a three inch tall three inch three and a half inch reflector
and i thought you know i'm certainly never going to use it none of our club members are going to use it so we gave
it away last year to the the county department of human services and boy they were
too they were really happy to get it and they knew of at least one person who would appreciate seeing that as a gift
come the holidays i don't say which holiday with the holiday season so um anyway
i guess i'm just bringing this up we wanted to put this in the back of their minds and maybe they something can get started with this that's right that's
right that's how it all starts so well that's great thank you
let's uh move on to some questions here
i gotta start it up helps
then we'll do that okay
i hope we all can see this uh the astronomical league has been on
the star parties and we've offered three questions each time the three kind of trivia uh questions about
something to do with astronomy before we do that we always like cautioning people about when they do
observe the sun uh these questions tonight aren't about observing the sun but if you get that hankering to go out
and do so you should do so in a safe manner and it isn't really hard to do if
you have the right equipment you want to make sure you have the the right solar filters that fit on the front end of the
telescope and not over the eyepiece you want to make sure that the uh if you
have a finder scope that it is uh blocked off so you don't accidentally shine it on the sun uh illuminating a
strong beam of light down to who's ever standing in front of it but anyway if you follow these rules
things will go well for you with a telescope so let's get on to question number one i think
i asked from last week there were three questions asked last week and we will answer them now we'll also give another
three questions this week uh last week in the global star party was carol orange our
organization's president who gave these questions
uh what is the name of the new astronomical league imaging award for women sponsored by explore scientific of
all of all people thank you scott for doing so now obviously the answer there is the
william fleming imaging award uh this is kind of a good thing to
bring up because i understand scott that molly wakeling is going to be on later on tonight
yes actually she will okay well she's the very first winner of that uh from this past year so
you can um tease her about it uh we're continuing on this coming year
and thank you explorer scientific for helping us make this possible thank you
question number two right out of shakespeare i i thought david levy would really like like like
this question right out of shakespeare ariel umbriel miranda titania and oberon are all moons of which planet
well the planet uranus um and i think these moons are also in a
pink floyd song but i can't remember the name of it i won't go there question number three
uh what unit of length is equal to about 3.26 light years now
astronomers we all know this it's parsec but to newcomers to the hobby or to science fiction
thanks to the thing is battlestar galactica parsec was tossed around every episode
and it was wrong parsley is not a i think it was a unit of time in the show
uh but no it's a unit of distance so those are our three questions uh the winners uh with winners we had uh
some what we do is we select uh the correct answers that people submit and put their
names in a hat so to speak and they will be drawn in a few weeks for a door prize so last week was norm hughes josh kovach
andrew corkill israel monterroso and cameron gillis so thank you for entering
uh we'll move on to this week questions for this week uh if you know the answer
uh send it to the secretary at astrolege.org they will not be announced tonight
obviously but they will be done next star party which i guess will be next tuesday night so please send it to
secretary at astrology.org question number one
which i think we're going to ask and then i'll say a few more words about it
yes this is question number one nebula immediately oh we aren't going to say
anything about it right now all right i'm sorry the famous nebula immediately east of deneb is known as a
the north american nebula north america nebula b the great nebula of deneb
c hubble's nebula so if you know the answer to that excuse me sin is the secretary of
astroleague.org
question number two number two question number two and what caused sun
lie in front of tonight or today
okay let me read that off again i just had to note that my internet was unstable there
and what constellation does the sunlight in front of tonight if you know the answer secretariat astrology.org please
question number three
which major planet is closest to earth tonight which is farthest remember they all won't be lined in a row and they all
won't be on the same side of the sun it's the closest venus
farthest neptune or b is the closest venus farthest uranus
or c the closest mercury and the farthest neptune secretary at astrology.org if you know
the answers to that one more those are the three questions i have one
more slide kind of a plug for this coming of friday night the astronomical
league is um presenting its live uh um zoom meeting
courtesy to help with scott scott roberts again uh we will be having
a uh i guess a holiday theme type type meeting some interesting stuff uh
kind of the spooky and strange um yeah you know well uh terry mann our our
secretary is gonna be talking about aurora soul of the night uh rumor has it that i'll be on it
talking about the moon david levy will be on it uh celestial incantations i'm sorry david i made up
that name i hope that was okay i'll be on there too
uh barbara harris we'll be talking about um algo algol the demon star and molly
wakeling who we were just talking about a few minutes ago uh spooky nebula of the of the night
in our uh two two more people uh mary stuart adams will be talking about passing between the worlds under october
skies not that i'm interested interested in saying because i'm not quite sure what she means by that and astro bob
who's always a very interesting speaker and always has a lot of great topics um i guess it's talking about everybody's
favorite topic black holes you know where matter goes to die uh you you can never
lose talking about black holes your audience will always stay with you so that's that's great but anyway uh this will be
this friday night uh see what they call it same bat time same bat channel type type thing so we hope
to see you all in um that's pretty much what i what i have unless we
have some questions and then i can try to think of some goofy answers uh there was just um
uh some questions about where to go find
a used telescope like that you know and and i recommended an astronomy club but
uh where else do you think uh and and cloudy nights was also recommended
um but uh where where would you where would you start you know if we're looking to
get a a used telescope well remember what i was just saying it's
just it's not just a used telescope it has to be a usable one right really usable means something that
can't be too frustrating to use um so you want to have something that actually actually
actually works so you look at places like second-hand stores or good goodwill
sometimes those have them but sometimes they're also missing components they're missing parts that's true and and yeah
you know at the old finders or the the it it's so worn out that the mount is
too wobbly to make it usable and these kinds of things if you're handy you can
of course fix these things and uh you know you ask where to find these i
again i as you said i think the best place would be an astronomy club over the years people donate stuff to
clubs and you know clubs are like everybody else they don't want to throw this stuff out
now so it's in somebody's house right now in their basement and they probably have several of these things right um
and it never comes up because uh amateurs who are really into the hobby that they're they're not
interested in this at all but you know these scopes still still work they still work that's right you can
still see the rings of saturn you can still uh with a small refractor i took one to
the texas star party uh one time i took a 70 millimeter department store level
type of refractor and um you know texas star party is really dark and uh i was able to find
the whirlpool galaxy with it and i called people over that were using big dobs to come and look
through the eyepiece you know i threw an inch and a quarter ip sign you put a decent eyepiece on some of these small
telescopes and they provide decent views you know and so uh you could just make out hints of the
spiral arms of the whirlpool galaxy with it you know so um
so there's a number of things that you can see with it occasionally i see in the magazines
challenges like uh trying to find the herschel 400 with a very modest
telescope and uh and and it can be done so you know and i'm talking about a 70 or
80 millimeter refractor reflector type of telescope um uh you know that three and a half inch
reflector that you got from celestron uh you know could could see a number of uh
yes a sizable number of deep sky objects so well i'll i'll tell you something that's
that's uh top secret so don't tell anybody this okay um but we're only
broadcasting yeah so just keep keep it down keep it down keep it under your hat
uh you've probably all heard of a program called the library telescope loaner program yes that's right that's a
great here's the top secret thing uh sometimes things wear out on these telescopes so
they don't work quite properly but the library telescope program group
of people have managed to figure out how to 3d print a number of
parts components i see so you know once you figure out how to
print it something that costs you know 20 30 bucks to buy
it costs you a buck 50. nice well uh you may hear more about
this initiative um remember it's top secret so don't tell anybody else but you may be hearing
more about this as time goes on very cool
that's that's what i have for tonight john thank you so much thanks for coming on and thanks to the astronomical league
it's great okay all right so up next is uh the one
and only david eicher uh and david is um uh going to
uh he he has shown us his treasure of minerals and gems uh
but he has so much of it that uh that uh you know it's been a nice series
um the the specimens that he shows are amazing and beautiful and of course
they're all made here in our home the universe so uh but uh
you know it's um uh you know some of the specimens i saw in the last programming that he did were
just stunning and i can't wait to see what he has tonight they're custom made to order scott
right here on earth on our own planet right nowhere else yep
we're not talking meteorites here and so this is the next chapter in exploring
how the universe makes planets and this is not an accident i'm going to try to
switch into screen sharing here this is not an accident this is the chemistry of the universe
showing us that what am i trying to do here sorry it's been a long day um
this is the chemistry of the universe telling us that chemistry is is uh systematic and and consistent
throughout the cosmos we know that through spectroscopy of course and we know that it's no
accident how planets assemble uh atoms uh logically and in a
in a precise order and before they get all mixed up in a blender and become rocks and other things like that
they're assembled in in order because the atoms in them are electrochemically attracted
uh in the kinds of very hot fluids that get going um as
minerals form like earth so we have about five thousand mineral species on
earth scott i don't want to gravely disappoint you we've only gotten through about uh
40 so far um so there's a little ways to go but i
thought this is a tanzanian tanzanite crystal here that's a very beautiful gemmy uh stone mostly from tanzania thus
the name that's a kind of zoocite and these silicates are very very dense
they're very hard minerals because of the silicon atoms in them so
they're very popular for jewelry and tonight i thought we would look at another popular
group of hard silicates that are colored by different impurities and they have different constitutions but they're all
similar and have these sort of substitutions of a few elements that go in and make make them a
little bit different and that is the garnet group this is not a mineral but is a group of minerals
and they're very popular for jewelry as well because they make nice little gemmy crystals
in cubic and isometric and tetrahedral and and other kinds of
crystal shapes that can be cut very nicely and they vary very well and they have strong color and all that kind of
thing the color from the in these gems comes from impurities of a few
iron atoms or in the case of the strong green ones chromium
or a few other contaminants that get in there and cover them and make them really nice and pretty
so i thought we'd do a very basic uh introduction to the garnet group which is a whole group of minerals and there's
six major types these are not all the varieties if you will it's kind of like talking about galaxies but these are the
major types of them and you can see that they have some sort of substitutions of some of the elements
in here in the same basic uh chemical formula here almundine that's
an iron aluminum silicate androdite a calcium iron silicate
grasular calcium aluminum silicate pyrope which is magnesium aluminum
silicate spacerteen a manganese aluminum silicate and uveravite which is a very
strong green emerald green colored calcium chromium silicate with those chromium chromium
atoms in there and you can see the chemical formulae there and it's uh it's too late at night
to get into the whole bases another time when you're really hard up for material scott we'll talk about
chemical formulae and how they're derived and what that means sure i don't want to get into that tonight it's too
late yeah we'll have to make all the connections though
yeah absolutely absolutely maybe a little earlier in the daytime um but here is the the sort of a
basic simple if you can believe it or not diagram showing you the basic crystal
structure of a garnet group mineral this is a grasula and you can see that there are
numbers of oxygen and silicon and aluminum and iron atoms that all go into
this crystal lattice and the hot fluids that flow um through
these sort of pegmatite rocks and make these kinds of minerals
cool down and they crystallize over long periods and the arrangement of these atoms is the same and so that is one
crystal lattice uh and then the more fluid there is the more of these uh lattices can build and
you get larger and larger crystals so that's how the world likes to make
minerals so without further ado we can look at a few examples of these these are from my
collection you can collect minerals too which is a very handy form of planetary
geology one of the areas of our of our love and our interest of
astronomy um because this is how what planets are made of and because we know
the chemistry of the universe is uniform everywhere we look because of spectroscopy that wonderful invention
we can imagine that although temperatures and pressures and other local conditions would be drastically
different from planet to planet to planet throughout the milky way galaxy and other galaxies
all the other 100 billion galaxies that are out there the basic chemistry would be uh pretty
similar on a lot of planets and so there might be minerals that are quite similar
to many of these 5 000 that we have on earth so without further ado we can look at
just a few examples of these natural minerals that don't look quite like the
you know the garnet rings you might buy but this is the the natural stuff in matrix as it were
or in country rock as mineralogists like to say that is these are garnet crystals that
as they are really dug out of uh mines uh here and there so this is
grossular it's called nicknamed raspberry grasular you can see that
from the color here and it uh is colored in part a little bit by magnesium and a
little bit of iron impurity in here as well and this is from a very well known uh
mineral locality in kohila mexico so this is where some of the very nice
raspberry grasular garnets come from this is a specimen that's about us and we are kind
of handicapped with these because to show you the really nice images here we're not showing the
their rocks live as it were but this is about a a sort of a uh a little larger
than a softball a size fairly good sized specimen there and so those are pretty
good sized crystals well this is somewhat smaller and these
are tiny tiny crystals and and this is that chromium-rich kind of garnet this
is from russia very well known locality there there tend to be sometimes with
minerals uh important places where some of the best specimens come from although
they can come from many many localities on earth uh some of the better specimens come from a handful of places on earth
and men mineral collectors and mineralogists are obsessed as we are with the ngc and the
the messier catalog and other things like that they're obsessed with localities of where minerals come from
not only a region and a state and a district
and a mine but sometimes even down to the specific shaft
or stop or horizontal at it within a specific mind even of where these things come
from so they're really obsessed with locality because that defines the the quality and and the origin of the
specimen so this is that chromium-rich really emerald grass green euverovite
which is an unusual kind of garnet this is a uh a kind of guy you can see
this is a huge crystal this this is uh about a six-inch uh piece of schist here
it's called uh the rock and and so you can see this is about maybe about a three inch
diameter big crystal here this is called almondine and these big dark red sort of
bronze fire red almondine crystals come from the alps this is from the tyrol uh
region of austria uh high up in the mountains there and they form there and and so this is that almandine which is
colored by chiefly by iron atoms
well this is back to some grossular from mexico again but showing you
um see if i can go back from from one specimen to another from the very same mine you
can get some tremendous variation in color and in what mineralogists call the crystal
habit the way that crystals form the structure of the crystals very very different even though this is from the
same mine this one and that one this sort of bubblegum pink
one here so that shows you the same mineral the same species the same mine but a good
variation so it gives you a huge variety of collage if you get addicted on collecting this stuff you know it's as
bad as collecting galaxies at the ivs yes this is one back in europe this is from
lombardy italy and this is a very famous locality as well and it's a kind of
andradite that's called dementoid and this kind of pearly uh olive green color of these uh sort of
rounded um crystals very popular and and a very good specimen of that
showing you kind of the variety of these are all very closely related in the same family of minerals here the
garnets this is andradite this is a with it with a an iron-rich
sort of silvery looking mineral there called hausmanite as well but this is andradite the the rich red garnets it
comes from south africa and this is a greek specimen now of
andradite and you can see very very different looking crystals here between this is the same mineral same chemical
composition different color because of the impurities here but they're both in part colored by iron
and you can see the larger crystals here of this greek specimen uh the chemistry changed as these
crystals were crystallizing were forming and that gave the crystals this kind of
dark boundary around the edges of the crystals there which is very unusual
which mineralogists call zoning this is back to a chromium uh colored
mineral this is a grossular garnet from the jeffrey mine a very famous mine
in quebec canada and it's colored again by chromie atoms that are the impurity
here and give it a very very strong green color this is a very common kind of garnet
called specine it's cut a lot for jewelry and and this is a chinese specimen there are huge numbers of
speciatine that have come out of chinese mines and are on this whitish matrix and are
cut and used for jewelry and you can see that kind of classic shape that can be cut into
stones there this is back to that same mine in quebec
as we saw a moment ago but this is a grassy layer that is colored by iron and
other impurities that give us this sort of honey orange color from this specimen
beautiful yeah i'm sorry scott i said it was beautiful
yeah it it you know the there's a tremendous amount of variety in in making a planet and we don't normally
see it because we see you know the the ground up you know soil on top of
our world typically but there's all sorts of adventure if you dig down and
and find some uh things that are a little more unusual and then i thought i would finish with this is a sort of a big
crystal here this this is from tanzania and it's called a specertine and is
colored orange by iron chiefly and this is about a two inch single crystal so a very large
crystal that could be uh cut and made into jewelry which again shows you the kind of you can see the
crystal faces on this um piece and again uh i will close with
uh the uh shamefully commercial um mention of
books and astronomy magazine once again good would you occasionally talk about
how stars form and minerals and all that kind of nonsense and that's all i have
today scott is another little chapter in how we make planets it's great it was great i'm curious
about something uh um the uh
you know of course we found all these minerals and gems and all their variations and stuff here on earth
do you think that we'll find those eventually if we mine uh uh you know
create mines in mars or there's no question now mars is very
mineralogically rich as well and and you can see the most uh abundant mineral on mars even looking
through a low power telescope because its orange color gives away uh its famous mineral iron
oxide aka rust but that's partly a joke but not really um
but mars has a lot of minerals now it doesn't have the free oxygen in its
atmosphere that we do there is oxygen there is water on mars it's locked up mostly now in subsurface
aquifers but mars probably has about uh you know
50 percent or so or maybe 40 of the mineral species that we have on earth oh
wow earth earth two point uh uh two point some billion years ago i think
i think it's 2.3 but i may be wrong there uh underwent a critical moment in in our
planet's history and that was the great oxygenation event the goe that was when
the uh the very simple organisms uh
cyanobacteria and other very simple organisms suddenly then not suddenly but over time
produced enough oxygen such that there became a lot of free oxygen in earth's atmosphere and oxygen
likes to what chemistry students react with things it's extremely
reactive so when we had a lot of free oxygen after a couple billion years or
one and a half billion years of microbes on our planet we
exploded the number of mineral uh species tripled them from about 1500
to near 5000 because oxygen combined with all these minerals in new and
different ways and it made life explode as well and the eventual
emergence of human beings so the great oxygenation event if you want to if you
can't sleep tonight and want to look up something on wikipedia was a critically important moment in our planet's history
for life for what led to us courtesy of the dinosaurs disappearing thanks to
that asteroid and the explosion of mineral species on earth all due to that great oxygenation
event a couple billion and change years ago now to answer your question so mars has
a fraction and it's a fairly good fraction of the minerals that we have but not nearly as many as we do and
a body that has almost no free oxygen the moon for example uh has uh maybe
about a thousand or less mineral species so many many planets out there in the
universe have a small number of minerals compared to an oxygen-rich world like
ours very interesting very interesting great
wonderful well david thank you very much and uh and uh you have a
good night and get some get some good rest thank you scott will do take care pal
thank you okay well up next is barbara harris
barbara is someone that i've known for at least 20 years uh i met her
initially through uh don parker and tippy dioria that were uh
people that were always at the winter star party but so i think barbara harris is probably also one of these people
that was at almost every winter star party that and this is a very famous star party down the florida keys if you
haven't been you got to go next year i'll be there broadcasting the event live so it should be a really cool
experience but uh barbara is also a discoverer of at least one supernova she
is very involved with the american association of variable star observers
she has a beautiful observatory down in near her home and she's an avid
astronomer and has contributed a lot to both the amateur astronomy world but
also to variable star research so barbara thank you very much for coming on the program
you're welcome scott glad to be here
okay
okay i'm trying to do this with my ipad
we'll hang in there with you barbara no problem yeah i'm usually on the desktop but i'm
gonna try my ipad tonight
uh
okay is my slide showing not yet
okay then i'm not sure
there's your camera back okay
get to share content
i know it can be done
[Music] nope that's not what i want
bear with me please no problem barb don't worry
so
i may have to get to another computer
that's fine i could probably have uh switch you up with uh with someone else
if it's going to take a few minutes let them
okay earlier today i ran into something very
similar where my whole sound system went offline so i had to fix it
there we go
so do you see my slides i don't see your slides but i see something that says screen broadcast
oh now i do now i do strange stars
and there we go you did it now sorry no problem
okay so tonight i'm going to talk about some strange stars in our
galaxy and in our universe so i'm going to choose five particular
stars that are kind of bizarre uh the first one is r corona borealis
and it's a star that's described as a reverse nova
i'm also going to talk about 3c 273 which is a star that is not a star
also going to talk about epsilon it's strange behavior behavior from one of
the kids and also tabby star it's the wtf star
and i'll tell you what that means uh and lastly i'll talk about barnard
star the fastest star in the galaxy
so many astronomers look at stars as just a way to guide them to a deep sky
target most amateur astronomers uh they're only
interested in what's between the stars and and using the stars as guideposts to
get there but each star is unique in itself and they all have a tale to tell
and some of those tales are very strange that we'll discover with these few that
i'm going to describe so the first star i'm going to talk about is our corona borealis
are as the variable star observers call it r corbor
it's in the constellation of corona borealis which is the northern crown
and this time of evening like this right after sunset is low in the western sky
it's uh it's mostly a spring constellation but it's uh tucked between
the keystone of hercules and the constellation botase
and it is shaped like a horseshoe and just
east of center of uh the middle of the horseshoe is our
core uh r corbor
now it is a variable star uh it's it's one of my favorites that i've been following for several years its
magnitude ranges anywhere from 5.71 to 15.2 mag
and it's the prototype star of the variable star group r chord for
stars and these stars uh they start out bright and then at irregular intervals they'll
start to fade
and this fading has uh is unpredictable
as to when it's going to occur and it's also unpredictable as to how long it's
going to last it can last anywhere from weeks months or years
and our corbor itself is a yellow supergiant that's about a hundred thousand times
as bright as the sun and the reason it's uh described as a
bright nova is because a nova usually starts out very very faint and then becomes very bright and
then it will gradually uh uh become
dim again but this star's baseline is very bright and then it will fall
at the regular intervals um and and basically recover and just stay
like right now the last observation yesterday was about 6.1 mag so it's
still up here and we don't know when it's going to to dim again and that's why it's
important to follow it and try to figure out what's happening when it's dimming and
if anything new is occurring uh in the star
so this is an artist's rendition of uh our core boar and this artist's rendition is based on
observations of the star from the european southern observatory using the very large
telescope in chile the dimming of the star
is thought to result from large clouds of dust that are spewed from on the star
um it is composed of 90 helium and less
than one percent hydrogen and the remainder is carbon and this is unusual since the majority of the stars are
mostly hydrogen so this star contains very little hydrogen um mostly helium and
carbon and it starts to actually spew
um carbon soot from the star and that soot
develops uh envelops the star and creates dust around the star and
that dust is what's what is causing the dimming of the star
and it's uh unknown how long it takes the deming to clear up but once it
clears up then we can have our bright star again
so the amount of dimming is basically how much dust is around the star and how long it takes to clear up
3c273 is the next star i'd like to talk about
uh it's actually a quasar or quasar quasi-stellar object uh it's in the
constellation of virgo it's a variable star that varies between 12.2 and 13.57
magnitude and it's another one of my regular variable stars
the image that you see identifying uh 3c273
is uh one of my images from earlier this year in march
march 18th and i measured it at 13.08 magnitude
now what's unusual about this compared to other stars that we see is this star
which is actually not a star and we'll get into a little bit later but it's actually 2.4 billion light years away
and it's probably the furthest thing that we as amateur astronomers are are
going to be able to visualize uh with our telescopes um
but this uh is actually not a star it's an active
galactic nucleus meaning that it's a galaxy with an active nucleus and uh
this nucleus is most likely a massive black hole and the name designation 3c 273 means
that it's the 273rd object in the uh the third edition of uh the
cambridge catalog of radio sources so this um
this quasar is actually a very has a very strong radio source
this is a hubble image of 3c uh 273 taken i think around 2013.
um and what's unusual is at about the 10 o'clock position
uh in the image this streak here if you can see my cursor
this is a jet that actually protrudes from 3c 273 and this jet actually uh
extends 200 000 light years away from the center of uh
of of this quasar this active galactic nucleus
so it's a pretty bizarre um item in the sky
and besides being a strong radio source this is also a very bright x-ray uh source
okay the next object that we're going to talk about is the star epsilon origi
it's one of the three kids in the constellation auriga uh so most of us uh
know about uh capella and the kids so uh
here's capella and here's uh the three kids this particular one is uh epsilon arriga
it's a variable star also and it usually varies from 2.92 to 3.83 magnitude
is 2 000 light years away from us and it's an eclipsing binary star it's
one of my favorite classes of variable stars eclipsing
binary stars are two stars that rotate um
around each other so that one star eclipses another now this particular
eclipsing binary has a period of 27.08 years it's one of the longest
known uh periods in eclipsing uh binary stars that we know of uh the last
eclipse uh of epsilon orega happened in 2009
um and the eclipses usually last three years so it was between 2009 and 2011
um that we had the last eclipse and the next eclipse is going to be in 2036.
now this is an a vso light curve of the last uh
eclipse of epsilon oragey uh this is uh i think probably
about a four year span uh of epsilon orage so the baseline is
close to three magnitude and then uh the eclipse starts
um around here so it it dims and then it stays dim uh
for for uh almost three years and then it starts to brighten again until it comes back to baseline
and uh so the next eclipse isn't until uh 2036 but we still monitor it on a
regular basis uh in case we find something else bizarre happening to it
uh this other picture is a uh an interesting picture it's taken by the
michigan infrared uh combiner and it
that instrument is an interferometer um that is housed on um mount wilson it's a
collection of six telescopes and they combined the um
they combined the light from those six telescopes to actually uh get an image of the star so what we're
actually seeing is an image of epsilon iraqi and what's unusual um
about this eclipsing binary is that what she clicked eclipsing um
the star is not another star but it's this disc uh this dark disc uh
that's actually eclipsing the star so it's one of the most bizarre uh
eclipsing objects that we know of and it has been a uh
a mystery for years uh trying to figure out what's eclipsing it
because we've known for years that it wasn't a typical eclipsing binary system that
something strange was eclipsing uh the stars but we couldn't figure out
what it was uh but it looks we we think it's this disc type object we still aren't really
sure what this disc type object is uh but we know um that it it's a disc
type object that's causing uh the eclipse every 27 years
now the next star i'd like to talk about is tabby star and it's labeled the wtf star
and tabby is a real person tabby uh uh
boyajian is a uh professor i think she's at lsu
uh but she discovered this um star uh
that was undergoing really strange uh behavior the star is actually what's called a
kepler input catalog star it's uh official name is kic8462852
and uh the kepler stars uh were discovered by the kepler space
telescope and if you don't know the kepler space telescope was launched in
2009 and it was launched specifically to hunt for earth-like exoplanet
and it basically only looked at a certain area of dye it looked at a
115 square degree area of sky between uh
cygnus and lira so it concentrated on that area of sky only and it looked for
uh stars that it thought may have uh transiting earth-like exoplanet
[Music] it would take images of the stars in that region on a regular basis
and they had a computer algorithm that would analyze the photometry and the
data that came out looking for exoplanets
uh at the same time they had a a group of citizen science
scientists uh in what was called the uh the planet hunters
um and and they would visually look at these these light curves from the stars in
this area and they found this star uh
kic8462852 they found that it was dimming
but it wasn't dimming in a pattern that they they knew it there was not a um
an exoplanet uh causing the deming so um
they started uh to investigate this and uh the the paper that that came out of this
was called uh where's the flux and that's what the the wtf stands for uh
they wanted to know where the flux that was coming uh from these deming
episodes and um
there were several theories as to to what was causing this unusual unpredictable dimming of this star
uh but it was really difficult to find what it was
some of the theories uh trying to figure out what was going on
uh one theory was that there were several comets uh surrounding the star and and
uh depending on how we the angle we were looking at it
they and what the comets were doing at the time around the planet of the remember star
um was one theory as what was causing the dimming one theory saying that there
was a ringed planet and asteroid clusters orbiting the star
uh one theory was that a a planet was basically swallowed uh by a
star uh and one of the most bizarre is that there was an alien megastructure
um around the star and the the press had a
field date with that one yeah that's that's one of the reasons uh tabby star became so popular is because
some someone proposed that if there was an alien mega uh
uh structure around the start that it would explain the the uh the brightness
uh the dimming and uh so that was uh that that one
kind of took off with the press anyway one of the leading theories so
far is that tabby's star is uh
basically being dimmed by dust surrounding the star um not sure where the dust is coming
from but that's one of the leading theories as to uh
to what's causing the deming and um we're
we're still monitoring this star is one of my uh favorites and in fact if uh i have
almost 80 000 observations in the aavso database
and i probably have about 16 000 that are of tabby's star
and as we speak my observatory's open and imaging this star right now
so uh i i image it every chance uh that i get
so it's a very interesting star and uh
i'm i'm glad that i'm contributing to trying to figure out what's going on with it sure
now the last star i'd like to talk about is uh barnard star
a lot of amateur astronomers know barnard star uh it's actually a red dwarf star that's
six light years away in the constellation of ophiuchus and that six light years is actually um
one of the closest stars to us it's only second to the alpha centauri
group as far as uh near nearness to earth
it's also a variable star uh it's uh variable star designation is
2500 uh ophiuchi its magnitude is around 9.55
and only varies by about a quarter of a ma of a magnitude
and we do know that some of that variability uh is due to flaring of the star
but it also uh might be an exoplanet around the star uh
there was an exoplanet discovered using the uh
uh uh it was discovered in 2018 um but recent data this year
calls that exoplanet discovery into question so we're still not sure whether uh
barnard star has a uh a planet around it but one of the most significant things
about barnard star is not only is it very close to us but barnard star is uh has a very high
proper motion meaning that it moves very fast and most stars
um that we can see have some proper motion to it that they're moving either
away or towards us or in some direction they're not just sitting still
it's just that uh the stars are so far away and the movement is so slow that we
cannot see the movement in our lifetime that when we're looking at at the stars
you know 10 years from now 20 years from now almost 100 years from now they're all
gonna look the same to us but barnard star has a very high proper motion
where literal you could literally see movement uh every year from the star and one of the
projects that i've been doing with this star is uh is i take a measurement i
take an image every year and i stack those images uh on top of each other and it demonstrates
how the star is moving every year so uh wow this is where it started in 2014
and then this is where it ends up in 2021 and every uh every little dot in
between is the years between 2014 and 2021
um so in our lifetime we can see that that
this particular star uh is moving and it travels about 10.3 arc seconds a year
so uh that's that's one of the claims claims to fame of uh bernard star
uh and and then now also it it may house a
exoplanet uh around it too
so uh i'm not gonna finish without plugging my favorite organization which
is aavso all of the stars i i mentioned are variable stars
and more information can be obtained about these stars and other stars
from the aavso all these stars can be observed naked
eye with binoculars or monetize uh telescope additional observations of these stars
will help to solve the mystery associated with them uh so uh like something like epsilon
arriga uh when we had the the big eclipse back in 2009
they encouraged uh uh people to observe it either naked eye
or by d using a dslr and we recruited a lot of citizen scientists uh to uh
to observe this in either naked eye or with a dslr so
a lot of that data that was collected during the eclipse came from citizen
scientists these are some of the books that um
that i i use for uh data about these stars and they're some
of my favorite books because i love stars and i love these books uh the one by
patrick moore called astronomer stars it basically uh has a chapter on
unusual stars like the ones that i've shared with you um so every chapter is a different star
telling you how unusual it is uh the next book the hundred greatest stars is also similar to to that book
also it basically looks at 100 stars and it tells you why it's a great star
and what's unusual about it and this book and the and the next two are by
james taylor uh uh james kaler is a professor emeritus
at illinois university and he's most likely the godfather of stars like
anything you want to know about stars he he knows about stars
one of his other books is uh stars and and their spectra and then this other book extreme stars
at the edge of creation these are all excellent books about stars and at the bottom here i have his
website um where he basically it's a website of almost any star that
you want to know about uh he has basically like a little biography of of the star
uh so he's he's the godfather of stars and it's interesting to to look at his
website and also read his books
okay wonderful so barbara um
it was uh uh one question that also came to my mind too is
uh we had learned about uh uh i think it's pronounced beetle geese
uh or beetlejuice or you know fatal gallows
i've heard it pronounced many different ways but um uh you know the red red star
red giant star in uh in uh you know near orion
right uh and it didn't so much you know i mean it was startling how much it
dimmed you know and we were we were all it was just something you could
obviously uh that you could obviously see and uh
uh we were um you know wondering you know is it about to explode is it you know there are a
lot of things that were coming out about it but i guess one of the um determinations was um
that dust had spewed out from the star and it was obscuring it
yeah that that was the conclusion and that one also the press had a field day
with because we know that one day uh and in astronomical terms it's
relatively soon that one day beetlejuice is gonna uh explode and become a
supernova so when it started to dim uh you know people started to to uh
wonder if it's on its way to becoming a supernova right and uh i i the press
latched on to that and it's like okay is it ready is it ready to go any second now it's
going to blow all right and it it was determined that it's not quite ready yet uh and it looks like um
the the evidence shows that it spewed out a lot of dust basically kind of like
uh our core bore um and that that dust accumulated around
the star and then as it started to dissipate uh it started beetlejuice
started to brighten again and even before that beetlejuice was known to be a variable star
and it would dim but uh this was the most significant dimming that we have
seen since monitoring um beetlejuice and if if you want to know more about uh
that that recent deming uh aavso does
uh weekly webinars usually on saturdays and this past saturday uh
a professional astronomer gave a webinar basically on beetlejuice and
what happened during that dimming period um so it happened live last saturday but you
can go to the aavso um youtube channel and you could view the
presentation for those who want to learn more about beetlejuice it was actually a
very interesting presentation uh so it's up on aavso's web uh
yahoo channel nicely youtube there's links to it from its main website which i just put up
there um and you know the organization you mentioned is 110 years old so this is
you know there's a wealth of uh information about stars there it is an
organization that absolutely will take you under their
wing and show you the ropes on how to make scientific measurements of stars
and basically prepare you for a life of uh of science you know so
uh which which uh the next steps and that is to do some pro-am uh yeah
and even though many of us amateurs have
uh cameras many of the observations in the aavso are visual
observations either naked eye with binoculars or through a telescope uh
you know there there are people with you know a hundred thousand or more
visual observations of stars and um visual observations are still actually i
think a few years ago ccd uh digital observations just surpassed um
visual observations but until a few years ago most of the
observations uh most of the data was uh visual observations and especially
bright targets like beetlejuice beetlejuice is actually hard to do
photometry with the camera because it's so bright it saturates so quickly
uh so um in fact that's how they discovered that
it was dimming unusually is the visual observations that were done in the aavso
database you know professional astronomers routinely uh look at
and monitor stars looking at the stars in the database of the aavso
and visual observations of the star was they were coming in and they noticed
that the star was dimming which wasn't unusual but then it started to jim significantly more than
um its usual pattern of dimming and that's what alerted the professional
astronomers to what you know something unusual is going on with betelgeuse
so especially bright stars like that and bright stars like epsilon origi
uh they're very bright and they're actually hard to do uh digital photometry on
uh like epsilon origi i met i monitor with a a
dslr um it's a little bit easier than than trying to monitor it with the ccd camera
right wonderful wonderful thank you so much barbara thanks for taking you're welcome evening
with us um gary alban uh says to says thank you
and he's watching on youtube he says looks forward to seeing you at the winter star party in february
um so we we hope that you're there um
centil nagapan i don't know where he's watching from but anyways he says very
interesting and uh anyways it's great great to have you on and to explore the universe of stars
it's wonderful okay well up next is um
is uh molly wakeling molly has i met i think molly only once in person
okay and it was at the um the advanced imaging conference in san
jose uh and then uh uh covet kind of uh obscured our ability to to meet face to
face again uh but she when i saw her i have mentioned the story before she had this big beaming
smile you know and she had just got this print of her uh image of ro fuchsis that
she had done it was just spectacular um but uh what i can say is and this this
is real uh uh that uh you know molly and i have become friends um uh although
we've only been able to do this virtually through through zoom and these lectures and global star
parties and stuff but uh and i i could have been more proud when she won
first place in the wilhelmina fleming award with the astronomical league so it's very well deserved and uh i guess
i think you might be a judge for the next one i i'm not sure of that so yeah
wonderful wonderful so it'll be great okay so uh i will turn this over to
uh molly wakeling uh also she runs the astronomy's universe
you can find her on many different programs but including her own website so
thank you molly yeah thanks for having me on again scott and uh tonight's target i was trying to
think of of something strange that i've imaged a couple of times and said that the whirlpool galaxy is strange-ish and
has some uh oops my focus has gone a little fuzzy there we go
okay um that it's got some really interesting
aspects to it that i want to dive into so go ahead and
get my screen shared here let's see yeah let's do that one
and get my powerpoint running all right
that was minecraft
um yeah so uh tonight i'm talking about the royal poke galaxy
and so this is one of my most recent pictures of it here in the background it's got a lot of cool stuff
going on so uh the whirlpool galaxy is a target
that many amateur astronomers are are i'm sure familiar with it's also known as messier 51
and it is a grand design spiral galaxy so that means that um
it the fact that it's a pure spiral and without any barge structure and i think it also has to do with the
number of arms and the fact that has complete arms and things like that make it this really phenomenal looking spiral
galaxy that just looks like perfection where can you find m51 it's actually
quite easy to find even for people who are kind of uh star hopping novices like
myself who tend to use mostly a computerized go-to for all my work
if you go to the end of the handle of the big dipper which is quite easy to
find and i think it's uh it's been like two and a half for three degrees i went
and looked it up and i already forgot away from the star at the end of the handle the big dipper alcade
and um kind of drop below the big dipper and that's how you can i can't see my
own cursor here that's so you can find m51 it's pretty easy to to hop to
you can also while you're exploring m51 you can hop over to m101 as well which is almost a little a little further
above the star alkane
some interesting facts some fast facts about the whirlpool galaxy it's even though
it's so close to the big dipper it's not actually in the constellation ursa major
it's within the borders of of canis fenetici which is a very galaxy rich
constellation that is a lot of fun to explore with a big enough telescope to
see a lot of those galaxies it's 31 million light years away so that puts it outside of the local
group and it's got its own galaxy group it uh was discovered by charles messier
in 1773 and added to his catalogue of things that one might mistake for for
comets that are not actually comets its spiral structure was discovered later by uh by lord ross in what did
what did i read 1780 something actually might have been lighter than that might have been 1800's
uh i'm mixing up things okay it's it's tuesday so tuesday after holiday weekend
um has an apparent magnitude of 8.4 so it's relatively bright and it's easy to at
least see the fuzz ball of it from a variety of skies it's a target i typically hit up
at public outreach events even in the city but uh and i've got some observing notes
on it at the end but you can see it in a wide variety of skies and of course the darker it is the larger telescope you
have the more of it you can see to include its spiral structure it is 76 000 light years across which
makes it about three-quarters of the diameter of the milky way so it's a little bit smaller width-wise
so m51 is really interesting and strange because of its interaction with the very
nearby galaxy ngc 5195 a lot of the time 5195 is kind of considered part of m51 as the catalog
object but it is a separate galaxy now it looks like when you look at pictures of it when you look at it in
the eyepiece it kind of looks like m51 is swallowing a 5195 like it's sucking
it in but that's not quite what's happening there it ngc 5195 is gravitationally
interacting with m51 they uh the orbit quite close to each other i
didn't get an exact figure but it has passed through like between like kind of
coming forward and back through m51 a couple of times
most recently sometime in the last 500 million years it's located slightly behind in 51 right
now and because of this gravitational interaction a it's causing a lot of interesting
things to happen in both galaxies so it's causing a lot of star formation to happen in m51
which is evidenced by all of the red regions that you can see in this hubble image
of m51 all of these red regions are star-forming regions and you think about the number of of bright
red nebula that we have in our galaxy there is a far greater number in m51
because of all this rapid star formation and you'll see on the on the next slide
um the star cloud that is formed because of this gravitational interaction of a lot
of stars and dust being ejected from both of these galaxies
and ngc 5195 doesn't even really look like it has any structure it's just been
disrupted a lot um they're not sure whether it's always been an elliptical or if it kind of if the structure was
disrupted and it kind of became this way i'm not sure but another thing about 5195 is that it
has a black hole in it that is actually burping out
a lot of hydrogen gas so not only do black holes accrete and sometimes uh
uh gas and debris fall into them but they can also kind of eject gas from
their accretion disks and and that and because it's been swirling around their accretion disk and
because the physics involved that gas can get very very hot very energized
it's actually sweeping out cooler gas in front of it and that's one of the other mechanisms that is spurring a lot of
star formation in 51.95 so this image here
it's uh it's actually an x-ray image inset of 5195
and it's this was some of the data used to observe that behavior in 5195 uh because
that that hot gas is is glowing in x-ray
so you can see in this this is one of my pictures here from the 2017 texas star party with my
dslr a good old trusty dslr and you can see
this kind of um i almost think it kind of a b shape or an e shape it has some
structure to it dust cloud plus there's a tail going out here and that's all ejected stars from
these two galaxies because it's glowing so there's probably there's probably dust in there too but there's there's
stars in here which is crazy cool in uh so i meant to say september 2020
it's not september 2021 on this slide in september 2020 a candidate exoplanet
was discovered in in m51 so a lot of the in fact all the exoplanet discoveries
that have been made have been in our own galaxy of course because that's hard enough as it is to
look for exoplanet transits and radial velocity shifts and things like that
inside of our own galaxy but this exoplanet candidate would be
the first extra galactic planet yet known if it is confirmed now we of
course expect that other galaxies all all have many exoplanets like our own there's no reason why they wouldn't
but we haven't yet actually observed one it was detected by observing eclipses of
of a high mass x-ray binary system that that planet orbits and that binary
system itself is really cool because one of the stars is either a neutron star or a black hole it's actually pretty
difficult to tell the difference in a lot of these systems because both of them are very small compact dense
sources and the other one is likely a b type supergiant so on the scale of
of spectral types of stars the the mnemonic to remember them is oh
be a fine guy kiss me and there's two other types l and t so i like to say lol
[Laughter]
or you can say via fine gal kiss me if uh if you're uh if that's what you
prefer to be that's what you like whatever you prefer um
so on the on the beginning of that mnemonic ob a these are hotter
bluer stars larger stars and then over toward the uh
k m k and and t and l stars you're getting into
small red stars and then into brown dwarfs and and whatnot um the sun is a
g-type star so kind of in the middle of that spectrum yellow main sequence things like that
the planet is uh they can tell it's that is slightly smaller than the size of saturn and it
orbits at some tens of astronomical units so that would put it um
it would be like it would be like a kind of similar distances to planets in our own solar system astronomical unit is
the distance between the earth and the sun it's about 10 times further away from the sun than the earth is so really
cool system i was reading the the paper published on the archive about it and they've got
just tons and tons of data on this and it's it's always amazing to me what we can figure out just from light
you know who's we've seen a potential planet inside of another galaxy i know that's mind-blowing i mean
this galaxy is what 25 million light years away 31 yeah 31 okay
yeah so here's some of the uh here's some images that are that were in that article on the archive
and um so the the left image is a little more zoomed out has uh the scale
marking is an arc minute and the x-ray source in question is
inside of that dashed box and then over here on the right this is
an x-ray image here on the left that's been colorized by the uh different x-ray
energies or xy wavelengths over on the right is a hubble image in um
i think it's in optical light or near optical uh that's at 10 arc seconds
of of the scale here and the pink dot is where that that star
system is located and right next to this kind of cluster here
and here's the actual eclipse data uh as the um the planet
uh went in front of the binary star system
and they have lots of other plots showing other aspects of this but this is the
background subtracted one where you can see that yeah there's a dip there that looks relatively statistically
significant so it still needs to be confirmed with another method but um it's looking oh
there's my kitty hello kitty his name is apollo um
looking pretty good that is probably something there so i like to talk about like to show
pictures of what these objects look like in other wavelengths because how we see them in the telescope and how we see
them in most pictures from hubble and from other astronomers
is in the optical wavelengths like that we can see with our eyes of course there's a lot more to the electromagnetic spectrum than the light
that we can see with our eyes there's light ranging all the way from very low energy long wavelength radial light all
the way up to very high energy short wavelength gamma light so um there's a lot of different types
of radio images out there in a variety of frequencies wavelengths the one here on the left is
actually the carbon monoxide one of the carbon monoxide emission bands
taken by a telescope in spain uh a radio telescope
and it's kind of cool to see where this molecule is concentrated and also to
remember that elements in space we're not just talking elements here there's not just elemental hydrogen and oxygen
and sulfur and things like that there's a lot of chemistry going on in space and a lot of organic
molecules are are made in these space environments
and you know here's one here carbon monoxide that we have here on earth a lot from
incompletely burning gases or fossil fuels like natural gas and and
gasoline and things like that so it's really cool to see that also exists out in space
on the right is a kind of a close-up infrared image from the hubble space
telescope showing where a lot of the the dust is at and also peering through
the dust to the bright infrared sources that are throughout that galaxy
of course we've already seen lots of pictures of the optical range so i'm going to skip that and go to ultraviolet i couldn't find a good
picture on google images so i used a piece of software called aladdin that i have that
has a uh a visual database of a huge variety of
of different survey databases everything from hubble to swift to chandra and
xmm-newton to just things all over the electromagnetic spectrum so when i can't
find an image easily on google i'll hop over there and see what is available from the huge variety of databases that
are in the aladdin software and it's free by the way and here's an ultraviolet image it looks like they've
applied some color mapping to this they're probably used a couple of different ultraviolet wavelengths from the the galex telescope
on the right is an x-ray image of the whirlpool galaxy taken by the
chamber telescope and you can see here at the core that there's some really interesting structure going on as long
as as well as several bright x-ray sources this is probably material around that black hole
in ngc 5195 and and lots of other hot stars and gas
x-ray sources things like that finally to observe n51 visually
it's a it's circumpolar above for people who are above 43 degrees north
for the rest of us in the northern hemisphere it's best kind of between march and october so for a lot of spring
summer and fall and that's kind of more to see in the evening if you get up early in the
morning you can see it for pretty much most of the most of the year
it is visible with binoculars under dark skies as a smudge in small telescopes you can see its
outline and you can see ngc 5195 and in larger instruments you can
actually make out the spiral structure i got to look at it through a 36 inch dobsonian at the texas star party in
2018 i think it was 17 17 or 18. yeah actually i think it was 17
night camber anyway one of those years and it looked like a picture of m51 it
looked like kind of a bluish picture i could see detail of the spiral structure i could
see the arm that appears to connect in 51 to 51.95 it was it was just absolutely
mind-blowing and i will also say so a lot of a lot of times people say that the andromeda
galaxy or m33 the triangulum galaxy are
the uh the farthest objects you can see naked eye
uh this isn't quite true some people myself included have seen i i've seen m51 naked eye i
was in west virginia it was high in the sky with averted vision i saw a smudge kind
of off the end of the tail the big dipper i thought at first maybe it was like an open cluster or a globular
cluster so i checked my star map and it's exactly where m51 was so i did the
the technique of you know you look away you look back see if it's still there uh you know double triple check the map
yes i saw in 51 naked eye from west virginia wow it's it
that was so cool the fact that it's 31 million light years away and you can see
it naked eye under a dark sky it's oh man it's just it's so cool
photographically it's really excellent at a variety of fields of view i've imaged it with my 500 530 millimeter
long takahashi telescope managed it with my 500 millimeter borg telescope
i've imaged it with my 11 inch cassegrain that is 2.8 meters of focal
length it's it's really excellent at a wide variety of focal lengths
deep images can you can get it pretty easily with even just 30 second exposures because it is quite bright but
deep images reveal the extended star clouds coming off 51.95 including some of the the tidal
uh features that are that kind of long stream coming off
and if you have like a hydrogen alpha filter there are tons of h2 regions to get and add some
really nice red and some really nice detailed structure to your color images
so it's uh it's a great photographic target and was one of one of my first
astro imaging targets back when i was first starting out i've imaged it
11 times now because it's just such a nice target it's so pretty oh yeah
and you do such a good job thank you all right here's one of my favorite images of it i took
this one when i was in west virginia when i saw a naked eye with my
76 millimeter borg refractor and it came out a little on the yellow side but um
i i quite like how much detail i got even with the small refractor how much of kind of the the title stream
i was able to get and kind of that b shaped uh star ejection region beside 5195 and
yeah it's i'm quite happy with this one oh yeah and there's also other
several other galaxies in the erics like i mentioned it's in canisfinatici which is a very galaxy rich
constellation so you can see that there's a little guy here there's one here
there's one here and i'm sure if i took an even deeper exposure over multiple nights at this
focal length i would find even more galaxies buried in the background and there's there's probably more in here that i
haven't spotted as well so yeah that's m51 you can find me on
the internet as astronomy images and astronomy.com is my website
thank you very much molly that's great i've posted a link to your website there and
um we look forward the next time you can come on so and good luck on your uh i know you're you're working hard in your
studies so yeah um that's that's fantastic i think i might have to stick to every other week uh still right
oh yeah yes but when you can that's great yeah yeah
by the way you were missing okey text molly uh i wish i could have gone it's uh it's
a big trip it's a long big trip for me i can attest to that with classes and
stuff like that i wasn't going to make it back in time for classes to start so yeah i can attest to that i just got
back today oh yeah and next year's a possibility though because i i won't be able to make
the texas star party i don't think so i'll be in class but i'll be done with classes in june
so that will open up my uh my at least remove some restrictions on
when i can go do things even though i'm going to be working very hard to work on my dissertation work so
i'll see i'll see what i can do yeah get that dissertation done yeah it took my wife a time some time to get hers done
and she finally got it so keep working at it that's important yeah yeah okay
great um next up here is pekka hautala uh
from stockholm sweden he's been on the many of our after parties for the global
star party and is uh has given a couple of uh featured talks uh with us but
pekka how are you how's everything out there in stockholm i'm fine thanks scott team
everything's fine cloudy rainy so is that normal this time of year
really normal yeah stormy and so so uh i get stuff done
like at home and today
because i have a lot of time to to think and
visualize about our universe and
i heard a small article about how we see the universe and big
bang and what i read that we all always think
backwards to the beginning we are researching what happened then
but it's hard to us to think that we are stardust
we all everything is from stardust and i begin to think
from the big bang forwards then
suddenly everything gets so clear that if you think all that stardust
or material and force flowing around and then
get a little bit uh closer together and begin to build some
some more mass and so on and it's like thinking
if you think from adult to baby face
that's difficult to imagine how to
crawl in in inwards but it's very much easier to think from
baby or pet dog to grown adult
and if you begin to think universe from big bang and forwards to our time you can realize that there
is small part parts that has more matter
and gravity gravitation and mass and then they get
they are going to build a galaxy and we have lots of those
points and inside the galaxy this they start
for for solar systems like ours and they are like billions of them
maybe on each galaxy and if you think
more further from big bang i was like thinking about okay
black holes what are they okay if this universe grows
and the mass grows maybe the pressure inside the galaxy
grows and the black holes could be like winds
that ventilates out the pressure i don't know but i i do that kind of uh
meditation during cloudy days
and it everything becomes more clearer if you think
like from the beginning to today then from today
to beginning you have to go backwards it's more for me it's more difficult to think like
that than from beginning to the this time
and uh the wonders even more is that there are planets without a
mother star that floating and they are probably a size of jupiter
and they're just looking for a mother star a rogue planet yeah
and so everything that became from the big bang
until today is unbelievable hard to think clearly
but a good start is to begin from the big bang and then get some small
places there there is stardust and mass
and then build to what we have today and
be people we didn't just appear to the planet earth
it is a long it's like a galaxy builds
and when you think like that 14.7 billion years it's not so long time
it's quite quite short sub period of time when you think in cosmological time
perspective so i think the the whole universe is
just in the in the baby phase so it's a lot more to come
that's uh i think we can absolutely be assured of that yeah absolutely so
that's what i do daytime and nighttime when it's cloudy and tomorrow i will
we have a clear day so i will do some uh our close star observations and
and train me to next summer to get a little bit better images
but i will do my best i'm sure it'll be quite good so yeah yep
thank you thank you for having me thank you very much thank you thank you great
okay uh we will um we will take a ten minute break and uh
we have more people coming up um uh including uh deepti gatam from nepal
uh adrian bradley uh rodrigo zaleda cesar brolo and maxi fellaris
down in the southern hemisphere so thanks for tuning in and we'll be right
back in about 10.
good to see you maxie again hey what's up man hey adriana how are you i'm
back a face that you have a a
big trip you done yeah it was it absolutely was a big trip
and uh it was fun though i um got a chance to see
some bortle one skies and of course compared to
what i have known you know what so far and um
i've got some more processing to do i did a little bit of processing um
you know while i was there i had a little tablet that had lightroom so i uploaded a few of the photos that i took
but i'm in the process of uh uploading photos now
from my second camera the uh one that's not modded i uploaded
pictures from my modded camera so i'm still off work so i have time to go
through some of these images and see what i got
but the few that i did collect that did some quick work on
look very promising excellent i saw a couple of words of you
that you upload on your facebook page and they they are stunning you know
it's amazing the sky makes it very easy to um
do to be amazed yeah to be amazed it's a lot of things i
yes that picture that i comment you you know a couple weeks ago when when i went with
a fr with two friends uh in in farm skies you know i remember saw it
with my own eyes and i and i never saw that and i'm glad that you have captured your
camera you know and well yeah yeah it's hard to describe
and that's how you know in my presentation i'll mention but it's very hard to describe what it's like to see
the full night sky um it's one of the places that star parties held
is is one of the few places you know touched by civilization and um
so it gets you're far enough away from uh any kind of lighting you know man-made
and otherwise and it produces some uh it produces some beautiful sights at
night it i did the little bitty test about how bright is the milky way
um and i uh i do have to say that i did see
it was faint but i did see a shadow um the
i don't think i have one of the other pictures that i took quite ready
but the brightness of the milky way i have a picture that looks like there's a full moon being covered by clouds that's
not a full moon that's the milky way shining that brightly through the clouds
are you shooting with dslr only yeah it's a dslr it's a
both wide field and i've got a larger lens on a tracker uh getting more narrow shots
yeah i will short order some young 135 now
it has they have stock in finland so
yes that lens that that land is killer do you think molly i can shoot
with i have asked you about the full modifier because film modified with the ordinary lens
it's hard to get focus and you don't have any lenses in the
front i yeah so um when you do that you pretty much just can't use autofocus anymore
which we don't really use much in in astro anyway um i have used that lens with a modified
sony a7s before and it worked fine full modified yeah without clear class so
that i i don't know for sure whether it had the glass or not yeah because the glass
you put it's clearly glass and that makes that you reach focus
and my dslr is is pure naked yeah um
[Music] are there black holes at the centers of galaxies
if they are how common are they we simply didn't know could astronomers ever hope to find what
lurks at the centers of other galaxies millions of light years away as guess
did in our milky way [Music] it would take another innovation in
astronomy to make that impossible and liftoff
on the universe when the hubble space telescope starts delivering clear images of distant
galaxies a team of astronomers gets to work they become known as the nukers because
their focus is galactic nuclei the centers of galaxies
one of them is todd lauer step one we take a picture of a
galaxy with a hubble space telescope it shows us where the stars in the galaxy are tells us its structure and
exquisite resolution key to finding supermassive
black holes is to learn how fast the stars in the galaxy are moving
galaxies outside our own are much too far away to measure the speed of individual stars but by analyzing the
way light is shifted from blue to red at different points in the galaxy astronomers can put together an average
speed of stars orbiting the center it's accurate enough to create a replica
in a computer the second step where the real work begins is to try to model
the observations and we actually do that by building models of galaxies in the computer
it's known as short shields method developed by princeton astronomer martin
shortshield son of carl schwarzschild his mathematics first described the
possibility of black holes martin schwartzshield's trick was he
would actually build up a model of the galaxy that not only had where
the mass was but also had how the stars were moving
for each galaxy they investigate the nukers painstakingly build a computer
model and then using trial and error to adjust the parameters of mass and velocity
trying to make the model match the original observations they got from the hubble
and we say let's try a star here let's try one over here let's have it go around this way let's have this one go
around that way and we do this thousands and thousands of times until we build up a library of
how stars can orbit this galaxy
success is when observations of the model match the observations taken with the
hubble space telescope but that doesn't happen
the models are missing something we try it again and again and again all
with no black hole yet and say gee we really can't get
the observations explained by the model only when they add an enormous invisible
mass at the galaxy's center does the model match the hubble observations
almost always we have to put in a black hole the center we can't match the observations without
a black hole in the model of roughly three dozen galaxies that the
nukers investigate virtually all of them require a super massive black hole
and since then other observations have made us even more certain that supermassives and galaxies go together
every galaxy we've looked for one we have found a supermassive black hole in its center
it's a stunning revelation super massive once an entirely
unexpected category of black holes may be common
[Music]
well we are back um and uh it's uh uh you know the theme of our um
of our global star party number 68 is strange universe and uh
uh so uh coming on all the way from uh uh nepal is deepti gatam uh
she is from the astronomical or the nepal astronomical society uh nassau and
uh she has uh been on many global star parties and um has been a host of a
global star party as well and uh so that's been awesome and uh so i'm gonna turn it over to her
dt uh often creates poetry you know really nice concise uh
presentations and uh she has she's done a great job and so
deep dee thank you very much for coming on to uh you know this 68th event
uh hello everyone it was really great it was great to be
back again after some after missing a lot of global because i was busy in the
old space week as i am coordinating in my state province um for the world space
week managing the programs and is our theme is this strange universe
as we know uh the universe seems uh strange itself and
its former sharing and all the things uh like how we bond how we are in all this
how it is linked with each other's everything now i have a small point that is trans strange universe they do not
know why people born and die even a child doesn't know why does he cry why people walk and move here and there they
do not know even why do they fear here they take of each other's do not
why thinking more on the many break in the side sky flies with stark clouds
filled with rain
oh i hope we haven't lost deep tea
hopefully she comes back [Laughter]
sometimes the internet falls a long ways away
okay yeah we can hear you we hear you now okay
we we see you we got cut off during during your poem
it's something in the universe wanted to try and stop you we can't let that happen
carry on carry on yes science sources for many galaxies and
planets some sleep in a cold for pleasures in cover blankets some got
some foods some got get food some do not at all and fall downs one become liver
another way see your crown saul does action but doesn't able to know snow
falls on hill like attitude soul does so slow again goes away from body injury
and others he travels in between what and dead further historian plants are hung in space in dark matters never fall
down even more in the track it's look better force of gravitations control walking up
off on earth god knows all secrets of strange universe in arts uh it was my
poem in having some glimpse i was working for uh
old space week uh entire this week or um in tattoo this
last two week
can you see my screen yes
[Music] now you might want to take it into prison there you go
okay very good as i was working in the old swiss week uh since last week uh in
moderating the programs different programs around my uh my province around my locality um
this week october uh 4 to 10 and this is my 60 mm telescope uh which uh i
have taken in the observation programs uh observing the jupiters and
moon in the sun using the solar filter similarly uh this is uh the glimpse uh
by which i have taken in this observation program night it is night sky observations around 6 30 p.m we have
shown we have stoned the moon to this kid and uh this these are the kids from
the orphanage uh they didn't have the parents and um in this small they lost their parents in
the small areas and the organization is helping them in uh carrying them and
you know the organization is carrying them and giving them education etc and
uh while we uh go to there and um tease them about the special astronomy and
show them the moon jupiter and their excitement level was so high and it was um it was so great uh to look them and
to look them up look them very carefully like how they
sit um mutually and understanding by having having understanding each other's
and how they see it uh while some while we are leaving from these organizations
and we were busy in the um the status for terrorists for some hours
and after we go to the uh down in the in their room and some were making the drain somewhere looking up
the cartons and somewhere uh playing each with each other's and okay
and and this is uh the uh cliffs that is um
of the one boy who was very excited uh to see the moon of festivals he was he
was say i want to look from finding scope so we let him okay you can see from heinrich scope and he was so
excited uh to see the moon and this is the uh programs uh that we
have uh then is this also the moon observations uh around the six uh six pm at 6 30 pm uh in the evening uh in the
school um uh we have taken uh this small kids uh it was a holiday
although it was a holiday but uh this kid were invited for the observation and they came and they really enjoyed uh
and uh next is um this is the program that is a presentation making
competitions in the school uh that is in the topic of introduction to astrophysics and
in this programs um this program was held in my school i was i was the organizer and i handled all
the programs about the presentation working competition all my juniors and my friends were participated in this
program and all my teachers and all those lecturers professors were there uh
to look up and the profession of the finance uh he was not from the science faculty though the profession of the
finance was present there and he explained how he loved uh he said that uh i'm not from this
field but i really love this space and science after listening them after listening my
students he really loved
all this uh presentation by the students and uh he was excited to know how the life forms
and all this universe fact and uh as he explained me later on i was
excited and expected other all programs and here's the finance teachers uh sitting here
my sister and he was so excited and he'll sit in this program entire all programs and listened carefully to all
the students and he got so excited and he was my science teachers and he was
there for adjustment of the students on the programs and this month of those all this glimpse
and today i'm going for this nike scale observations in another orphanage home
and looking after all more excited and to see this kid excited kids and to
expecting to teach them more and i have also tried um
sidewalk astronomy and i set up my telescope and take uh in the outside of my home and i just
i was putting the telescope there and my small kid was here and he said oh what's that and i said uh it's a telescope and
uh he was like can you see the moon can you see the jupiter and can i see and okay i let him
yes of course you can see and when he was he kept his eyes in the eyepiece and he was like whoa it's the
moon and what's that in the moon i said it's the crater and
okay and is there any creatures in the moon and any things are what's the black spot in the moon
and uh he said i also want to see the jupiter and i turn uh out of the status of into the two features and what he
said um from my telescope i can see this jupiter's very finely
but uh i can see the round safe and not uh clearly because it's a 60 mm telescope so when
you see this jupiter and moon and i invited him for the solar observation
next morning you can come for the solar observation because you sit near to my home and he comes to near um early
morning and see uh okay i want to see the sun you as you
have promised me yesterday and uh okay i saw him the spawn too and like when you
see the black black spot i saw his foot in the sun he was like
it doesn't have the sport we can't see this foot here
um like all those old old mains old main and green margarine fathers all were
there for singing this moon and it is they believe in the traditional belief and they were like
making joke like am i going to uh pray this moon can i take the anything to pray
okay and they were related uh with the astronomy and uh traditional astronomy basically will strengthen instruments
and i said them always and creators and it was really fun uh to take uh the
telescope and observation in the public creation teach the people what is this
and to share them for the astronomy inspire science thank you
thank you so much dt is great it's great uh we had uh
at times some interruption in the internet but right now it's like it's very good so
remarkable really so thank you so much and it's wonderful it's really wonderful to see um
uh you know the uh the children uh getting involved with
uh astronomy and uh and for nassau to
uh you know cross the bridge to all people of all ages you know so it's it's
wonderful it's wonderful uh are you spending um more time with
nassau and uh uh in presentations i mean it seems to
be a very active club yeah i'm involving it always this week
is actually the next coordinator of holy spirit week is monsanto is he has been here in the next uh in
the the previous old uh easter party when he sees the restaurant coordinator
and uh she decided uh to divide the work in all the province we have seven province or called state in the nepal
and she divided all these provinces to east of the member of the nassau uh uh junior
members member of nasa and i am handling the my province uh all
are around this i have tubal district that is in our um province and i have been uh going
attendings all the presentation com programs present in um
90 observation or solar observations i am handling in today as i'm invited for
uh coordinators and people invites me in this different school college and me
with my summer friends that it's pretty starker and all this team you know we
have team from and around here and we go togethers and
conduct the programs and return back like we are conducting
through the nassau it is once this week uh this province coordinator are afflicted uh with directly indirectly
with the nassau and nasa is handling like uh serious work right after portion
of nasa is helping us though he is not connected with the old space week monsoon is uh but he is helping us uh
directly and in the every phases so and beside this all this uh beside this
we are making the outreach not only for the old space tree but for the pro
promotion of the space science and astronomy so yeah um
i'm connected with old space week that is our events and also in my own
organizations there is um me with my team from my organizations where is
helping me out here for observation program uh they come together and tease the people from small kid and uh the
people that's what about what the astronomy is and we call it tb uh working from the nasa in my own organization
astronomy enthusiast in nepal and uh in the event of uh we'll specific for now
wow okay all right that's great all right dt thank you so much that's
great um we uh we hope to see you uh maybe next week i don't know if you're what
your availability is like but it's always a pleasure to have you on global star party thank you so much
thank you all right um let's uh let's bring on adrian bradley
uh adrian's just coming back from the texas star our oaky tech star party not the texas star party okay
okay tex and uh so what did you think what was it was your first time i think
right yes it was and um i enjoyed it um a couple things
that i remember being really cold the first night in the rv asking around for sleeping bags and uh
blankets and that made the experience a little better
they're very um i think yes they are yeah the showers are warm the tarantulas are cool to see as they
walk through the uh you see them kind of on the fringes of the uh property
and there all they're trying to do is get back to back home before being stepped on
sure and uh and the hospitality and there's so many
um people there the group that i went with university lowbrow astronomers and i had to give a
shout out to uh camp lowbrow we were there um the uh they had been going when there
was mostly visual at okitex and um
it's become uh there's a lot of astrophotography that goes on at okeetech so
the for them it's a little bit of uh it's a sad change but it's kind of the way things are when you go to star
parties you see a lot more folks coming in with huge computer setups and
tints and if something goes wrong as it invariably does during the night you click on the a bright light and then
the visual astronomers yell turn off that light um it you know it can get a little testy
but by the time the night's going usually everyone's sure into the uh night so i will as anticipated uh
share the screen some of you i know harold locke is out there a couple of others some of you have seen
some of the pictures because i went ahead and shared them while i was out there
out at okitex uh and on our way back we um i shared a few photos so i will describe
what i've got here and try to go in chronological order first this image
um most of us aren't uh able to get a milky
way shot using our iphone um why this isn't coming up okay it's
coming up over here and this was the best i could do
that's pretty good iphone uh yeah keeping in mind it's the iphone that's an iphone iphone i'd like you to
try this at your home uh your home state or home area
wow this is one of the shots that basically lets you know just how bright the milky way is
yeah it's bright enough adrian you got to send that to apple really i mean i will send that to apple
definitely yeah and if they want to use it for marketing purposes i'm sure they will
that's right um so long exposure that was a 30-second exposure
on a track putting the iphone on a uh star tracker barbara would you ever leave you know 10
15 years ago that you could do that with a phone i mean come on i know incredible
yeah that was my experiment to see that there were a number of pictures i took
just to indicate how bright the milky way was i'm going to show you a picture
now this is the brightest milky way i had to date and actually the terrain looks similar in oaky text this was at a
portal 2 sky after a minute so comparing what you see here to what i
took with an iphone in 30 seconds that's the uh the difference
um this is and i'll do a prelude this is um if it loads
a picture of the other side of the milky way that i'm trying to load here and it will eventually
um orion and this was with a non-modded camera
um and that was about a minute or so exposure to get that um i had where was that taken adrian
that was taken at uh in michigan uh port austin um near the thumb
so comparing that to this close-up of the milky way core this was a minute long exposure at oaky tax
at okeechobee and wow
gorgeous that is yeah i knew you were going to take some pretty mind-blowing uh
you know night sky photography like this so it's uh it is uh for any of you who have not
been to okie tex or the black mesa state park in the panhandle of oklahoma
folks it's dark real real dark you know and real clear you're up about
i think about 4 000 feet yeah yeah fourth time no you're not up so high that altitude is a problem for you but
the transparency is awesome and uh it's beautiful so here's another proof of concept thing
um clouds came the first night and this is what it looks like you're at the
northeastern uh corner of the field where the star party's held
um this was a wide-angle lens you can see some of the distortion and you see this shining through
this is something else you probably won't see at your regular sky depending on where you are you know unless you're
out in a place like this the glow the milky way shining through the clouds the glowing it's light
pollution you know yeah it's not it's it's the glow the milky way and
yep it's milky way pollution you have let's see you mentioned something here i
think this image is the other side um and you've got this normally this would
be your light pollution this is air glow that the camera picked up yeah and
there's all sorts of so i used the aha modified camera so you've got
the hydrogen alpha data of things coming through here look at that the milky way is like a
dagger coming into this beautiful uh like a pool of uh
of of effervescent green coming down through there and then this beautiful
uh you know landscape of the plateaus and stuff out at black mesa yes
it's it's beautiful and it looks like you got the andromeda galaxy or something off to the yeah i did let me
i'll fire i'll fire that back up that you got the andromeda galaxy just
sitting over here and m33 over here
okay the triangulum galaxy is over here ngc 752
the double cluster and the heart and soul nebulas which a lot of visual
astronomers tried to view and they couldn't and they they'd get asked are you trying to do imaging because the hydrogen alpha
the the light output tends to only be visible if you've got a camera picking
up that light right um then there's there's a lot of there's a lot of uh
there are nebulous here that i still haven't looked up to say what they are but they all shine through
okay norm hughes is go ahead there was not many either
international dark asiations uh members there i probably
think yeah there were so here's one when you wait for orion to
rise and go ahead scott you were saying someone had a comment oh yeah it's norm hughes
watching on youtube he says i've been to the park but not to okie tex been here all my life and haven't gone
to okeetex crazy dude you gotta go
i've been i've been many times it is a i can attest after being around the
country around the world this is uh one of the darkest sites that you can go
to it's it's really great yeah all of these are roughly 30 seconds
it's easy to get data would call it there's california
the pleiades someone pointed to me that this void you see sort of this shape around the pleiades does exist it's it's
a bit of a void in that in that uh part of well part of the galaxy
um now the pictures are pretty rough i i actually am gonna process them directly
and so they'll come out a little clearer so you've got the air glow you've got orion rising
and all of the data that comes you know with barnard's loop so
the moment of and i'll even this here's a close-up um
if it comes in a close-up of the heart and soul this is a single one-minute frame okay bubble cluster heart and soul
all right now can you go back to the previous image one more time yes let's go get it find it here it is i
called it orion so you have a detail of that but this look at this and and when
you look at it just look at the whole uh view of it you know because now what
you start to see is like this formation in the center like it's
like you're looking at an orion nebula or something or some sort of matrix of of uh bright nebula and dark nebula uh
and it looks like one kind of object you know and it's just beautiful it is
beautiful this is this is this is something you could sit in front of and contemplate for hours really
it's a part of the milky way that we milky way shooters typically don't shoot this part of the milky way
um i did see one the southern hemisphere gets to see this view we get to see this view a lot more
in our hemisphere the northern hemisphere and um it you go to a dark site to truly
appreciate it and i'll show you the shot of the a couple shots that i
kind of itching to show and i'm trying to hold the uh good one for last i thought i had a
an orion rise with a regular a regular modded camera here's the same area
with a camera that doesn't get modded and this is what you can still get
in roughly 30 seconds we had some haze the final night so it produced this
image you still have air glow and they're the dust lanes even in an
unmodded camera there's a bit of a void and because of the haze you could get
this cool effect with the larger stars as orion rises
so there's it there even if you don't have a modified dslr
or you're not using a wide field lens on an astro camera you can still take beautiful pictures
using the camera you have um and
now for the let's see there are a couple star trails
um there's one the mesa this was about a 15-minute exposure those of us that love
star trails here's yeah you know here you go and
this milky way picture to me define also defines how bright the milky
way is look at this detail and look at this twilight
you know if there was a if there was a uh coffee table book on the okietech star party this should be on the cover i
mean absolutely beautiful uh it shows um the the star party field the people
interacting there you know the red lights that amateur astronomers use and this amazing uh you know the drive of
the you know again the dagger coming into um uh from the sky down to the star
party some clouds in the background to kind of give you a terrestrial feel you know and
then you've got this meteor that's streaking across the sky really beautiful amazing
yep and amazing to me is how visible the milky way is
and how twilight still hasn't stopped yeah it's dark yet yeah it's bright over here
yeah so this was one of the shots of the night from a city that's that's from the sun yeah exactly exactly and uh
so yeah this much detail you usually have to wait till you get dark enough
even in that portal 2 sky before you see this but the milky way pops out at you when
you go to a place like this and what else pops out at you uh before i click on this picture the
story goes like this i woke up at around five i was just
tired i was cold and i got up walked outside
and i saw this if it it'll come up in a couple minutes but uh
it i was floored when i saw ryan over this hill winter milky way and zodiacal light
crosstalk look at that that's beautiful and this picture doesn't even know i love
that yeah so i i said oh i guess i gotta take a picture walk back into the
sleepy eyed got the camera 30 set it up when a 30 second exposure
did a little bit of editing so you could see this okie and tex are the two flamingos and
they're over here somewhere um you know they get put up there there were a lot of photographers that
started going up here and up over the other beats to get beautiful photos yeah but i would challenge them if they'd
stayed on the ground and we're up at five in the morning to see this you wouldn't even need to be up here
you can get a youtube right it's just as beautiful a picture and of course when you use a modified camera orion is
exposed and you can see the uh you can see more of the details there
now barbara what do you what do you think of the i mean just that that here i'll put this gradual gradient of of
light getting darker and darker but starting to show like these bubbles of nebulosity and uh
the zodiacal light uh coming across it's just it's just super i know it's really
beautiful yeah i just took a picture of the zodiacal
light last month for the first time and got up early yeah
it is uh yeah and you got up early to do it i took mine um
my first zodiacal light in michigan um it was spring
equinox and um i started i as i went out i noticed it
and took it of course going the other way with sunset along the ecliptic
um so i you know instantly recognizing this what you're not seeing and what i
tried to capture but i still have to process a crescent moon with earthshine
coming up over the horizon right and you know in the zodiacal light so that
picture is forthcoming if i'm able and it may have to be a composite
but um that picture is one that i hope um i hope to be able to share if i took it
i took a few frames i wasn't happy but i did my best to capture the moon itself
as well as the um just you know just being in the zodiacal light so that's uh that's coming up this
is uh my friends trailer and some more star trails i took a few different
exposures so when i layer these together chances are the star tree is going to look a lot longer
um it's beautiful as it is i uh you know i have to uh i mean really
tip my hat to you adrian because you're capturing a feel of the okey tech star
party that really this is the first time i've seen it photographically you know um yeah uh the
you know i've seen and i've seen a lot of photographs taken you know images taken from okie texts okay but uh
um you know seeing these wide field views uh you know the amazing uh you
know spectacular effects of the milky way um these are things that you actually
can start to visually see except for these colors you know the
colors are now coming out uh because of photography uh you know adrian talked a little bit
about uh you know doing uh you know mixing some images or doing a montage
not a montage but also um you know layering in some images uh
uh yeah to capture the moon and stuff and sometimes you have to do that because in photography and you guys that
do imaging know this you only have a certain range and then it stops
yeah right and then now you go into a different exposure you know deeper you know and
start to mix these images together to try to capture what you can see visually or how it
impacts you you know how it impacts you seeing it you know and so it's not it's not like
photo magic or something but these are the tools that astrophotographers have to use absolutely
to convey to translate the feeling yeah when we want to show something
as we saw it sometimes we have to put like scott said put some of the pictures together because of the dynamic range of
the camera sometimes we don't and sometimes it can surprise us
uh depending on in its knowledge of your camera and how bright things are i'll
end on this picture um for those out there that do have um as i do we have um you know we're
part of a church and you know we we think of the universe both in and of itself and then
spiritually with um with god those those of you out there that don't can look at
this and just notice you know this is a beautiful picture if you know anything about camera
photography you would expect this to have been a 30 second exposure this was an 8 second exposure wow an 8 second
exposure on a tripod with um iso turned all the way up to 8 000
with a 50 millimeter lens f14 was the uh aperture setting
and i i went for eight seconds fired uh with the cross and this part of the mesa
basically a little hill in the background and look how much detail i got now
wasn't perfect but just right over here if we stop here
right over the cross if you think about it most milky way shooters are not going to
go for eight seconds out wherever you are
and you can't you really don't really get to do that unless it's so dark in the milky way so bright that even in
eight seconds you can still get this much detail you know this much nebulosity going on
there's m8 m20 i believe these are and i see gary has joined us could tell
me uh if the m7m i think
17 m16 there's something here my wagon walking up the milky way is
something that i would love to do but just haven't spent enough time
um getting all of these uh objects and there's actually a couple clouds i
don't think this is a part of the milky way a couple of the clouds here are just dark
they're in a lot of places they may be lit by whatever light pollution or you know local cities are there but
um here the clouds are just dark so stars just sort of disappear as clouds
go over them and that's you know is the old uh this shot that scott loves uh i'll have
to send this one to you scott uh you got the clouds yeah i'll print it and have it on my
wall it's great yeah i'll get you the i'll get you the high resolution copy
okay and um you know you've got milky way here the sun the twilight has not fully gone
i've got some hot pixels here but it's cool it is
you don't need it gone in fact yeah perfect like it is so that's cool there the offshore one
telescope under the cover adrian yeah this one hasn't been yep they haven't opened it
up yet yeah so i think from the united states yeah this is a little closer view
i i said i'd end here's your closer view i got into my hiding spot so i wouldn't be shining
lights on anyone and a little you get a little more milky way than you do where i am at 41st parallel
i think this is 39th parallel and this was a 30 second exposure there's some other uh
ghost here because um the first night one of uh one of my friends from
our camp camp lowbrow did a little bit of uh imaging himself and then he went to purely visual
astronomy and that's where everyone else was i went out and got a few more
shots but so this was the um this was also day one after some of the
clouds had disappeared right and you know this was
this comparing this in 30 seconds to
this in one minute gives you sort of the idea of what it
takes to get the milky way at a dark sky a lot of
data just comes at you if you don't require as much time
to get the same amount of data and that you know when it goes to classic astrophotography
um or wide field you know imaging on a tracker
dark skies you know they things that you can do with dark skies just it shortens
your time and capture here's one more iphone milky way
which will come up in probably 10 seconds at least i think it will yeah
another yeah it's a very crude photo it's dramatic it is yeah this was handheld
and the glow the milky way still shows up wow you know you're right that's amazing
that's that's how bright the milky way is there and i think i've shown all these photos
here so yeah that concludes gary you'll laugh at this one i didn't show this one and this is why because it uh this was
my one minute attempt at getting the belt while i was there oh
look at that i got the flame you have the orion uh there's the horsehead exactly
yeah you know yeah yeah
so and then i think a dust spot on my on my lens so
yep and and that's how i got round star so it was it was a good start and then i just went into
i went into other stuff so adrian i i wish i wish all my friends that are
astronomy friends that have passed on could see your images because they would be utterly blown away they really would
you know so and this is i think this is the one that i love the most you guys watching it
right now live just soak it in because it's awesome yeah and then go out and see it for
yourself this is mostly what i saw now i had the aka modded camera so
you know you got some more you know you undress the drawing a bit and you got some more detail there's the
rosette right here like pelicans over here somewhere and so you've got a little more detail a
little more red in the photo but when i tell you i stood there and this is what i saw
um yeah you know just imag imagine seeing it you may not see all of the
you know all of this detail but you would see all the stars and you would the milky way was that visible and so it
was like sacred and when you say it's spiritual it absolutely is this stuff
strikes you to the core and this is why people go to really dark sites and this is why we need to protect
our dark skies yes that that's a great note for me to end my uh presentation on thank you
scott for your annotations and uh to all of you here pekka gary
cesar maxi rodrigo and barbara thank you for your uh
kind comments looking forward to seeing your work uh don't have to go to work for another few days so i can hang out
and listen in so uh thank you all
right yeah so next time uh you know uh
you uh you know if you're looking for an amazing astronomy experience go to the
okie tech star party it's super super amazing super dark um
and they often have many back-to-back nights of clear skies so
wonderful okay all right so we are um moving on to um
uh rodrigo zeleda down in chile uh rodrigo is um uh you know
someone that he's still the owner of uh north optics down in uh la serena but um
uh he is and he still does backyard amateurs astrophotography but he's
becoming a professional astronomer a professional researcher and it's great to have him on
global star party thank you rodrigo has gone for you
yes yep we can see you rodrigo
hi um tonight i
share with you my last picture from my bachelor and the
other nebula is a great object for a
photography and i take a the picture from
two days ago and it's a very nice picture [Music]
i i will use my screen
in
18 minutes
okay
we can see it do you see my skin now
we do i see some beautiful uh images of uh m42 and 43 in ngc 1977.
yes this is my my final imagine
this this picture is uh take the shuttle diet tonight
when my refractor telescope from las vegas in the city in
in my backyard it's a nice photo for a
audio nebula it's very difficult study the center is a
very very bright and and it's very good
and reduce the lie in the center and
this is my my last picture wow look at that
this this picture is for a little time is a
20 photo to 20 seconds in the center
you see the tradition museum yes
beautiful and my plan is uh with this result which made the
20 seconds for imagine is it take four hours break
20 seconds and in the last star party
i i plan to share with you the photo of the
and i work for the data of the professional telescope in
chile's vista telescope this telescope is work in
infrared and i i
see the the nebula in infrared is a
very nice and share with you this photo
this photo is oh wow it's a comparation for the
sector of the messier 17
this sector is a busy in visible visible light
and this sector is is an uh near infrared
and uh wow this is the
no is it uh rodrico could you explain a little bit more um you know we're looking at the the visual image and the
uh near infrared uh why why is the um parts of it kind of this more
dark brown color and then we have this cooler uh blue color is it is it because
of the uh uh any uh energy or temperature differences what's happening here
well in the near infrared this this color is a false color it's a
and the light is a the the lights blue is for a
near to the visible and the um [Music] okay brown is
more near for the infrared more in the infrared okay interesting because you start to see
you start to see uh areas which i think are star formation you know those those dark tendrils of uh
of uh dust that are coming in and uh probably at the tips uh of them and maybe towards
the edges are you know primordial stars or newborns stars right yeah the
the light infrared um is more a transparent for the dust in
the galaxy and the this area is a
dust and the blocking the
the light spectrum in the visible spectrum in infrared uh
this is transparent for the dash in the in the galaxy this this this project
maybe is for a studio valley of the star
and the this teleco is a survey take a many many pictures
and the astronomer using this picture for another study for a
global cluster and extruded a new galaxy
is not visible for the dust in the galaxy and this picture is in
the this area in the sagittarius and this nebula is uh
wow is completely different yeah what do you like in the receiver
yeah look at the dark nebulosity you know towards the top and left and
uh it just makes it in stark um contrast to really bring out this nebula
but it's just you know it's scattered with all these beautiful stars it's it's amazing you
know yes amazing this is
the oh yes and so you can see also the star
formation area right how does this make you feel
rodrigo and you see an image like this i am
when i when i the open [Music]
fields images yeah and process yeah it is amazing
yeah i process and now about the uh
um 500 clear 500 and
i mean okay
and this moment is uh amazing it's a
first time and i see the strokes on galaxy and stars
and new for me and
i found for astronomers it's imagining new images it's very very
very yes you know it's it's hard it's hard to describe uh
such an amazing image like this because you know an astronomer like rodrigo he
knows he knows a lot of what's going on in the background but trying to
uh it verbalize that okay beyond saying amazing okay is just really tough
because this is creation you know this is creation this is destruction this is
you are at once seeing the entire dynamic of what's going on in star formation and the star cycle you know
and it's uh it uh it it grabs the um
you know the or captures the uh the understanding and the moment and
everything that uh it just takes it beyond words it really
does so and then i'm not trying to i'm not trying to uh
be real tongue-in-cheek about this but this is uh these images and to witness this kind of stuff is really
um fundamental to what drives astronomers to understand more and more
and more about star formation and what drives our universe
yes the most um impressive one imagine is uh
in the disks on the galaxy the milky way um
in this imaginary you see many many galaxies
your light is blocked for the milky way in the infrared the dust is a
transparent and you see the more galaxy in the the film
it's beautiful and this is my presentation
rodrigo thank you so much that's wonderful that's wonderful uh i know that caesar and maxie are
waiting but gary palmer is out there and it's quite early in the morning gary did you
want to share anything with us hi scott nice to see everybody on here again
um yeah i am i'm up late anyway i've been running the workshop this evening so or
overnight here so um yeah we're uh sort of ticking along so it's a few bits
this week uh we've done some soda weather's not been brilliant we've got the change of season now so we're
starting to get the fog come through get a couple of hours clear or the days are a little bit hazy for solar
um but i'll share a screen over so
i've been doing some more work on this 3d system on the solar oh wow so we can actually see that
generally when you look at this two-dimensional yeah you'll just see the prominence like that on the edge of the limb
and this would be the same if you image this on a standard system you can't actually see that this is coming back
onto the surface it's very hard to actually see the the filament there and that the filaments are drawing
off of each other so um still needs a little bit more work on it but
um that's detailed with one of the songs wow that's amazing
that's using the double stack system um it's only 80 millimeter aperture so it's
pretty close up for 80 millimeter at this time of year incredible go to the standard system so
this is a cork on the uh fcd-102 yeah you'll see it's there um
but the double stacking just adds the contrast that's the big difference between the the two images and also you pull out
the active areas so if there's any areas with flares or things like that you can really see those starting to uh react
on what's going on you know more and more of these kinds of images
these incredibly high revolution images of the sun have been coming out from guys like gary
and a few others but uh gary is really really at the you know leading the pack
in a lot of these guys doing this kind of imaging it is because he spent so much time uh knowing understanding the
equipment uh improving his his skills including his basic skills but uh
and and teaching others you know by teaching others you you your skill level gets higher and higher by doing that um
but you know you're staring right down into uh you know the cauldron of a fusion reaction you know it's amazing
thanks it's um it just takes uh i think it takes potions
that's the same with all of this it's really about um patients looking at what's going on
looking at the images that are coming in and working out whether you can change anything whether you can improve on that
or whether you know something in the equipment can change it's not all based around the weather
um i thought we'd put this up and have a quick look at this this was an hour's worth of data last night on m33
um and just run through and see what's there for an hour you know so um we can
just run off we've already stacked and calibrated the image but if we did a quick
um photometric color calibration on it we can set it up so
if we go in type the object number 73
search it out but that we need to acquire the pixel size for
the camera and then the focal length of the equipment is about 500 millimeter
so i've heard a few people complaining that this is not working um this photometric color calibration
they're getting problems it's normally in the focal lens you know if you you have to work out that if you put a
reducer on the system your focal lengths changed and this is actually going to plate solve it off of a database so
it needs to be fairly correct it's going to solve against the styles that are in your image against the database that's
held and once you've put in the the actual target
the pixel size and the focal length is pretty straightforward if you just apply it to the image
it will go off it will reference it download the data upload your image and then it will work
it out from there and a color calibration it's a fairly good system because it's calibrating it on the night sky
that's on record so any changes that go on there then it will be updated in your images
so it takes a couple of seconds for it to go through but it is fairly straightforward
and gary this is uh this is another feature of pixen site right yeah yeah
i've played with lots of different software played with extra pixel processor
um we did some tests on that and the new weighted batch uh process or scripting uh pics insight
it's far quicker now you know people used to use that pixel processor and deep sky stacker because they didn't
like the amount of time but i always say good things come to those who wait
yeah so if you if you're prepared to wait you're going to get the benefit out of it
so that's the image calibrated still raw so we need to brighten it up a little bit to see
what's going on and so next thing is really a little bit of uh work on the noise in the
background because if we zoom into it we can see it's a little bit speckly it was a little bit foggy last night it was
like bits of sort of misunfold coming through so they're going to affect that and it's pretty straightforward to do
this as well so we can just go in screen transfer function and then we want
uh multiscope linear transform and just set this up so this is pretty
straightforward start off on noise reduction we've got four layers there
first one starts on three all of these are around 50
so next layout noise reduction we come down to two
17 again 50 this is one of the easiest processes
but combating noise or high gain of the cameras you can get all sorts of artifacts some filters actually create a
lot of background noise just in their generic design so these new extreme filters the dual band filters
they're very noisy um so down to one for the third layer and the last one
yeah if we click on it go to noise reduction bring it into point five which is half
there we go and then the same thing again fifty percent so with the image being
linear or raw it's not stretched yet and if we use any mask on this it has to be
stretched the easiest way to make the mask is use the clone tool at the top this will give
you a black and white mask but we need to stretch that to be able to use it otherwise it can't mask anything off
so if we use the histogram i don't know what happened there
histogram tool select the mask
okay then activate this and with your screen transfer function hit the nuclear button
that puts a false intensity in here no one transfer that into the histogram
so we don't need to do any settings or anything all we need to do before we apply the histogram is reset
the main image we're only using that for the light intensity that image is permanently stretched now
so you could even post that out on social media yeah once it's at that point where it goes but we're going to use it
for a mask to bring it across attach it to the name bar
select the main image and then what we need to do to apply the noise reduction
just move that up out there we need to invert it so we've got our mask controls here we're going to invert
the mask so it's covering the objects in the stars and then this just removes the visual
effects of the mask it's still active got the orange bar at the top and then we apply the
morphological transfer multi-scale transformation and that you'll see it makes a massive difference
to the noise uh gary hey how are you
i'm good thank you can i ask you a question uh you you
don't convolutionate the the mask
there's really at the end of the day you have to look at it how much data you've got so if you've only really got an hour or an
hour and a bit's worth of data um there's only so much you're going to do with it and that's the same with any
image it's like adrian if you've got an image that's a minute yeah and you've got an image that's five
minutes there's so much more you can do with that image that's five minutes the image that's a minute you can only do so
much with it so you have to ask yourself is it really worth it and that's the key thing if i had 10
hours worth of data here then i'd spend a lot longer on this but that's the big difference with
this sort of thing so if we zoom into that and go over to the edge
and then we go back you'll see that it's flattened down the background
so it's smoothed everything out it's taken off the harsh edges on the styles that makes it a lot more appealing
what we can do now just going to drop this down so we can close the mask off
there we go so at the point with this image whether um
i'm stretching really and the easiest way probably is mild stretch i use that a lot on things like um
andromeda orion things like that holds the callback and also it holds some style color
yeah and what we're after is trying to keep style color in the images because this actually has quite a lot of nice
colors in this target so there's a lot of hydro now for you can see the pink sitting here and the idea is is to try and
retain some of that so if you use a mouse stretch on this yeah then it will mask over some of this
and it will stop it over exposing so we put a little preview box here
go to my stretch select the preview box
on the image that's its background reference you can adjust this value and take this up to
like 150. i'd generally stick with this at 0.125
apply it to the image it come back white because i didn't reset it but it's fairly quick
i should be able to actually do these in my sleep now [Laughter]
yeah you've done it for so long yeah to me to me it looks like uh
you can take you know a few years to get to this level but then again
um i know you've been doing this for quite some time so and he does it every day yeah maybe a
couple of months six weeks like the six week workout you
know yeah okay so but we've got this here it's a little bit dark but i purposely
want it like that at the moment because it's retaining the colors in those styles so yeah
and give it a little bit of a kick using the curves yeah so we can put up a live preview
just give it a bit of a kick contrast just pull a little bit more out
apply that to the image and now what we need is to actually add some color to it
so at this point with it being a one shot color it's quite green
yeah um you've seen the green cast they use the 90s filter on it so that adds a bit more green to the cast on it
so probably before we add the color is just neutralize some of the green in there so you can use the scnl
um when i can see it there's there there you go now you don't have to hit it a hundred
percent on that you can bring it in at 60 still retains a little bit of diversity in the middle
there we go so we've got that back now we need another mask because we want to add some color
and add in the color we don't want to add color to the background you know we only want to add
color to the styles and the object so with this mask i don't up the histogram
and select that particular one always reset the histogram otherwise you
add two processes it holds the one from before and then the left hand slider we're
going to slide to the right just apply that to that image so what that's done now is it's darkened
down the background and when we apply it to this one
if we actually put the visualizer on yeah you'll see that it's allowing the styles through and it's allowing the
core of the object through and that means now we can go to the curves tool
put on the live preview and switch it into saturation mode and when you switch it in saturation mode you've got the uh
purple lines where the first four boxes join raise those up
and you'll start to see the color coming out in the stars and then the target
okay just a little bit more not a lot more somewhere about there
so last thing we really want to do is just bring out some more structural detail in the middle
and probably the easiest way of doing that remove the mask
it does take a minute to do this process and that's to use starnet to create a
style mask so click on the create style mask
apply it to the image and then just sit back and wait for a minute until it's done
wow
uh gary i have the quick question during the processing
what is the maximum exposing time with lund 50 or so
there is no maximum exposure time it's about keeping the histogram set
so the the histogram for the camera i generally use sharp cap because the histogram is very accurate in it that's
the only reason um but the histogram really wants to be about 50 to 60
yeah on its linear scale and if you get it in somewhere around there you'll always get nice surface
shot images okay so i mean it's no problem so sorry
three minutes yeah three minutes fine but really you have to look at the amount of files i mean if the camera's
really fast yeah then there's no point in recording three minutes worth of data so
what what camera are you using 178 mm right the 178 is quite a high resolution
camera so you would actually find three minutes on that the time that you stack it is probably distorting the images
yeah um less is more with the camera like that so um you could probably record 500 frames
and stack a hundred and you get yeah you get really nice detail because it's a high resolution
camera yeah yeah so the 174 um
it works very different on its pixel sizing so on that camera you would probably want 3 000 frames and stack a
thousand or hundred yeah but the 178 um yeah i would just be
like 500 frames 1000 absolute maximum and keep your stacking number low
oh okay 150 frames you get some really nice images
now that both of those or all three of those images that i showed for solar earlier were off
of the 178 equivalent they're off all player one version nice
we'll try tomorrow yeah we need some sunshine there's some nice activity going on at the moment
yeah thanks corey that's right just gotta wait a couple of minutes for it to do this star mask
unfortunately when these images are really big it takes a little bit of time to calculate everything
so what's the weather like out your side stop sorry say that again what's the weather
like out your side you know it's it's uh amazingly warm uh it's it's been uh
in the 70s you know fahrenheit and um
very nice you know for this time of year arkansas can be very unpredictable though you know it can be
raining cold hail tornadoes snow and then warm again so
you know we've had it really warm over here it's really unseasonal
this october's had some very warm weather um and normally we would be going down
to you know maybe around 10 degrees something like that celsius right you know dropping into the sort of high
50s something like that but it's been up just you know just the bouldering on the
70s um for most of the week right yeah okay so we've got ourselves 28
degrees outside right now and it's uh you know it's 10 o'clock at night so
last night it went down to 3. it really plummeted it went
you know have a real drop off that's the reason why we keep getting the mist in the fog
right temperature changes yeah so we've created a style mask all we need to do
is revert back so we've got the styles in the image apply the style mask
then we're going to invert it and we'll just run something like a hdr
multi-scale somewhere around six or seven and put the d-ring in on and that's to try and draw out some
structural detail in the core
there we go wow all we now need is a little bit of brightness so we just run a little
lot on it so normally run this at about 1.5
just up about 80 should do it just have a look
here so if i feel that's a little bit harsh what i might do at this stage is just drop back one
and then bring this in a little bit lower so bring it in at about seven instead
sometimes it's a little bit trolling out just depends on you know what data's coming how much you've got there
but always prefer it a little bit softer you can always sharpen it up later on and then something else
it's beautiful this is real simple processing it's real basic stuff this
okay so we'll try that again now put the yellow that's that's pretty good
that's pretty good yeah and then we'll play around with this and see whether we can get this a little bit nicer
it's easy to go too much i think yeah there is a balance there
you know with all of this i mean sometimes it works out that you don't need to do the lot you know i mean it's
it's really a case of it's down to you i'm probably going to leave it at that
that looks pretty reasonable detail's nice very nice very interesting in overcooking it
so yeah that's that you can play around and add some more color in and do some other
bits to it it's um it's really down to you as to what you like to do
beautiful yeah i've always been a fan of the accuracy side where you ended up the
image where you ended up where you stopped for me would be something to just that would be the post on social media
m33 you you you could get it's like the backgrounds in a lot of
the images just in the background really really dark so they've got a really harsh edge from the target into
you know space yeah and you know by keeping it soft and keeping
it gentle you make it a nice image even though it's really very little data i
mean if we take an hour's worth of data it's not a lot right
we've got a we've got a measurement over here in our little corner in michigan a gentleman that uh
minimum 30 hours of data we've named it after and we call it a strupel so uh if you can spread if you get 30
hours of data you you've had a struggle with doug strubel uh scott you may remember
yeah he's been on um the show uh he's got two he'll take two rigs um
and point it at the same target and go 15 hours each and then he'll and then he brings his
data i believe he uses pixen sight as well um if not you know he may still be
back in photoshop um he gets an awful lot of data and then he goes in and he plays with it so
there's no real substitute for data you know yeah at the end of the day but i've always looked at it that you know
not over the weather you've got other things going on you know um time limitations with work all sorts
of things so the average person is only getting a couple of hours a night if they're lucky
and a lot of that time is kicking the equipment trying to get it working yeah so
if you actually really boil this down yeah with frustration um they are struggling to get it so it's
really coming up with ideas of how to process that and get the maximum amount of it just for fun
you know here to do 30 hours is probably you know a couple of weeks something
like that because of the weather you know this time of year now i'm at the moment for the last week or so hour
and a half an evening something like that before the weather will change yeah so it doesn't matter what it's
forecast you just know that that's gonna happen here but sort of three miles over the mountain
we've got the massive lakes here and they hold the water so if you get yes temperature change you'll just get
the the mist and the fog start rolling in yeah and i can watch it yeah look down the mountain and look in the
valleys and you can see it starting to build and that's it you know so 30 hours a day
sorry guys that's right as much as you'd love to do it is it's just not possible
you know right that's the thing yeah it's one of the things i saw being out in that dry area
um at okitex is uh you know the difference in the sky itself
and we were up 4 000 feet um you know there's
it it's a difference in what you're able to pull down
in the same amount of time changes as well and there's just more data to get
um in a shorter amount of time but then you'd have to travel
to wherever those and i don't know over in the uk i don't know how far down in europe you'd have to travel to get to
something similar or if you'd have to just come over to the states in order to
be under those skies and then thank you for having me um two to three here
yeah so that's a nice even though you've got humidity that's still a nice sky when you can
shoot at it is your issue here yeah yeah but it was like i was looking at your
milky way shot and really our cutoff is well certainly for me here is about
just underneath the swan so at the triffid anything below the trifid
really you're not getting yeah and see we we can i've actually got the portal 2
milky way behind me and that's our cutoff the uh core
yeah and then you know under over here we're done
you know this is when it was rising and it this is about as much as we get in michigan where i am that's our our
portal 2 sky and uh when i go out you can look at maxie's behind him he gets all of it
lucky maxie over there look at it look at his milky way behind him he's got both sides of the core going he's got
the whole bulk so yeah it it does depend on location most of the
shots but like you're like you're demonstrating a lot of really good astrophotographers
you when what data you get you can use tools and really bring it out
and you know there you go and i think that is the thing you know the progression in the software has really
allowed you to do that it's only a little bit with the equipment as well but in general i mean we used to do the
same with a dslr you shoot for an hour on whatever you got for an hour and always yourself that
old adage that if i spent more than an hour on processing i was bored so i still really run with that yeah
everybody seems to think that i love processing that i hate it it's um that's why i find the easy ways around it yeah
it looks like a lot you've got a lot of the scripts there figured out and fixing site you've got your process down so
first you want to do this to the image here are the steps now i want to do this here are those steps and it i know it
takes a while once you get it you're just going through and then you're looking at your image to
see what you got to take your next steps so if you've got 30 hours a day today
you're going to spend a lot longer on it processing it if you put the effort in you you know capturing it you're going
to spend more time processing it but for this sort of stuff that's probably why i'm into wide field
astrophotographer wide field you know it's nightscaping it's
um however you want to call it um you have something to start with and
then from there you're tweaking it to make it look more real or if you i've seen surreal stuff
done and i i i draw the line where it gets to be a little too surreal
you know and yeah i prefer having accuracy excuse me getting the milky way shots
with the um the meteors coming towards you you know and all that sort of stuff it
doesn't do anything for me you know yeah it's got a technical ability in photoshop but that's about where it
stops right you don't all of it has to have some realism
and i think that's what drives a lot of astrophotographers is you know you're capturing
what is there or what was there back in time um in a sense so
that that's really what you're trying to represent and what drives you is probably to improve
on that exactly you know the next time you go out is to improve on that to get a
better image than what you did the last time so it's a never-ending uh battle no matter what level of astro we do
um you know we we're trying to show what's out there and what's real
and um you know it's you look at an image and say okay yeah
here's where i could improve um i remember what i saw with my eyes and you know the eyes tend to
yeah they're your best critics it's like yeah you saw this this and this trying to capture that is
it's kind of a chase that's no different to putting a phone on the moon is it
if you put a phone to get that exposure correct to actually resolve any detail on the
moon even though it's going to be small what the eye sees what a camera sees is
totally different you know yeah and um i think that's what makes it interesting
you know and it's trying to pass that fun side over to people it shouldn't be a chore it should be
that you're having fun doing it and enjoying doing it absolutely yeah absolutely well gary thank you so much
man thank you for coming on yep up next is uh uh cesar brollo um and uh all the way
down to buenos aires and uh um we're always happy to have you on cesar thank you for
for hanging in there it's a pleasure
listening to gary about after photography
the conversations with adrian the pictures
of adrian of the sky the processing the image processing live image processing of gary palmer
it's really it's it's an honor to be here let me change my internet
connection it's something that i think that maybe you cannot listen
good because i think that okay well now is working i don't know how many
times um well i i in in
in the last salary i i show a live image
of jupiter um uh with a
five inches uh maxotop telescope from my balcony
i process the image let me share the screen
and this is that i i could uh
i could uh very nice meg sir yeah yes it's do you remember that
i remember that you tell you say you say say uh ah i can see the the
the brother spot not now now again this is this is
the the spirit of this kind of image the processing is
is choose the better pictures
make something with the wavelets and west a really really
uh uh very balancing right with a lot of turbulence and
you know a mix of uh of of uh local
seeing or local turbulence i don't know if the word turbulence is okay it's it's okay turbulence is in
spanish but i think that turbulence the mix of air hot air and you know
the big part of the program of the scene the movement of the air um with different temperatures of course
and well last saturday
we was preparing the next saturday star party in observatorio
san miguel and we went to the observatory you know to to work
in some plans for you know for receive the
people for where we can put the telescope to to show
leave image um of course that we start
i'm i'm carrying my my telescope the
first slide [Music] 1 27
maxutope and i took a series of pictures of
jupiter um computer and something something of
the surface of the moon look the difference between these pictures
and the next let me hear wow
telescope wow excellent uh yeah
yes it was really different because when when i had uh
we had a little balancing but only uh because um
it was incoming a uh shutter spring current and when you
when you have this kind of of current you can see something like like
um you know like a grain of uh all
uh 16 millimeters filming
when you use uh maybe high high [Music]
high as a high sensation film
and you see the grain moving in there in the because it's not
very high yes a very high altitude turbulence um
but we can make something great for this and for this telescope was a really uh
a huge uh proof that of quality
here you can see uh a part of the red spot
here the one to three storms some people told me that
this one are more recently this storm this uh uh
points in jupiter maybe in the last few years uh
um here were i think there was a europa hero
i don't know if you can see uh was interesting because uh first of all i
thought that they had some out of collimation in the telescope
but uh was not was the the the uh
how do you say was ah [Music] an optics
like effect of optics but by the by the [Music]
by the turbulence exactly to replicate another rematch
of the of the satellite ties um was very interesting because when
three different telescopes were fractures maxo tough um schmidt castle and we say
the same is enough because i i know how how uh uh and cali may and colin kalimate
telesco is and i say come on i can see something like a ghost of the aio and a
ghost of of europe um but it was great to see that
the optics work very very well and here is a crop of a computer or i think that is from
another video because the position of this is a little different
here um the surface uh of the moon in in uh a
quarter crescent and very very very nice to to shoot
spectacular this is a very yes this is very interesting um
thing to see in this friday i don't remember the name now but it's
in the first time of of of the present moon you can see with the shell of this and
this is very very interesting not all the time you can see that
here another picture pretty pretty for you know for a telescope that that the
name is first life that you think in the first telescope
really really we had a lot of fun
and really the details comparing i have pictures that my friend
fernando ricardo took with his uh with his uh mid 10 inches telescope ace
as hfc is um of course that have more resolution
especially in jupiter with details that we
thought that really was the limit was the diameter because really we can saw that uh
the the difference only in the same times between the same camera type
um the same another mod for conditions uh
was uh really the difference between uh five inches and ten inches uh but in
the moon was really really similar the details um
was really uh a great to have a telescope that
you can carry in a small you know in a small
box or and that work in this quality of of image
here with the do the concept oh that's beautiful i love that yeah yeah yeah
here uh [Music]
that was amazing with here was a scorpio
here is the last last week in the
global sort party in my balcony my balcony observatory here is the
school peter nice my yeah yeah you know the mess that i
have here because it's time to make my daughter and my wife is planting
tomatoes or a lot of things um i i i confess that all time i
kick i kick the pots oh no no no no because in the darkness you
know scott yeah i know they say oh i see come on i kick the pot i put all in
there well i sometimes i make a disaster because you know it's not a big balcony
yeah yeah right yeah i can imagine what your wife is
saying in spanish yeah yes yes
yes of course there are some people are watching this but i i
can't pronounce it but i think what you can what what what you say that's nice yeah i really
i imagine it yeah i here do you have a a wide view of
the balcony this was the last week with the the
with the position of peter uh going back
in the background of the buildings and the the
the clouds that every time that they put the telescope in the back on
okay of course that need to appear um well this is this is the
the this is the thing this is a picture of this saturday of the trees and
confusion and the conclusion this kind of tree is very nice it's the name
is araucaria this is a great tree is from the patagonia but
you can plant in buenos aires and grow and have maybe these trees have more
than 50 years so it's very interesting the shape is it's
really different yeah
here is here is uh fernando ricardi that is a member of
of uh uh victor gosmos that is our group to
to restoring and preserving the observatory here is the willing of the century
and of course that i'll prepare a lot of uh pictures that's next saturday to show
you in a presentation for our next uh event is is the
the first uh the last uh one of the last event in the year
uh this one is for all public er in november we have uh only four
amateur astronomers with their telescopes um next saturday they come
the people come come come
go to his uh telescope too but you know it's a mix between
all people and is it it's more for the people visiting the the
the installations and know who is the the plans to to rewild in the terrorists the equipment
and here what is is the the flyer one of the flyers here we use a laser
from from the used refractor and well this is a pla part of mariano
poisson for of course for solar that is he's a genius for that
um well and all different uh expo exposition
is for uh to talk us about about
the all things of of uh things about the
observatory um november is for for amateur astronomers of course at maxi
faggieres and anybody that can
come [Music] can go to argentina no problem
and uh really of course that i need to advise maxi knows that that is a suburban skies
with very light pollution sky
like maybe a little less than buenos aires city but you know it's
it's to to to share a time with the people that love astronomy and
curious people at this time before this saturday in november maybe we we made uh
discussions about astrophotography if anybody
if somebody of us adrian gary scott uh
like to appear in a video conference
for next time yeah i'll volunteer sure completely completely yes yes for us
it's a it's a great because it's especially for for amateur swimmers uh
maxie of course that he he need to come here in november because he told me that
yes his wife his wife yes i i know that he was thomas
no but in november yeah yes in november he promised me
that he came to buenos aires to visit us in the observatory
yes you have my word
and we have to see that because the pandemic situation it doesn't allow us so now
well certainly we can we can be together again
of course yes and and of course i will send you this eco from here
ah yes yes we are we are waiting that okay
uh so maxie you're drinking the mate right yes yes it's a company
to well i'm here alone right now but but
and also when the the nights maybe it's it's cold but tonight
it's fine a little wet but uh
yes i prepared the dinner it's a
unattached it's a pie from with cheese and and
what a jam come on and so i i will be eat that more later but
the mate is a ring to to have that company
when you're talking and of course if you have friends to in person you you share it
but but when you say thank you that means that you don't want anymore
oh i said that's it thank you
usually i say thank you can i have another yeah yes no no no yes if
for me edward needs the same no sense that you because because maybe you see
okay i'm an american i don't know the culture of this crazy people but the first time the first time they say
no if you say gracias thank you yeah you are you're
saying that you yeah you know the idea because thank you i don't know i i
yeah yeah sometimes sometimes yeah i'd say we say the same thing and then we go great thank you like that you kind of no
i don't know why thank you because you say thank you
why come on i think it's because uh it's maybe a
little offensive to that one who is uh preparing the mate
yeah if you say okay i don't want any more so that's maybe
yeah the body language would have to help yeah yeah maybe maybe see that that
changes everything we we're so used to having to say it over the internet so you have to
you have to fill it in um the body language i would tell because i would
uh like you say all the time says i would say come out and bring some more
or i would say no thanks and push for the audience
that doesn't know what mate is it's kind of a tea right like uh
something yeah and it's got a lot of caffeine in it right it says sounds
not too much caffeine okay no no too much not too much maxi
no no i i just was talking we were talking yeah you notice that maxi stays up all night
okay right you know
if you change the the the way that you prepare the mate yeah depends from the region it's
offensive to another place from where they prepare for example in brazil they all
they prepare the mate but they prepared a different way they put the they share
about the plant more to a corner and then um
they write yeah and then put the number one brazil only
why and also i think it's important some neighbor from europe but here now
it it can be prepared with some libation
as well to kick it up so i i'll have to find out when i finally
make it down there to see how the different present the different ways it
can be preferred looking at the night sky it sounds like a delightful time to
me are you using a t-shirt from netherlands or i'm crazy
no no no sorry the shirt is just somebody came up with
this from years ago and yeah it's orange but it was an old softball shirt it's you
have hardball baseball and then you have softball with the larger and it's slow pitch
back in the those days i played slow pitch softball and now now i just play
hardball even though it's worse it's harder to do regular baseball but i enjoy it when i
get the chance no i may try and play this week but we will give you
a t-shirt of river play of course i look forward to that i i will enjoy it
i will wear it often yeah again remember still figuring out the promise
of paxi yeah yeah still figuring out how i'll get down there but it's it's on the
list it it will happen just get on an airplane adrian and go yeah i well i
have to pass that through the wife and weird that's different yeah and that then we we have the pandemic to consider
this long trip was a road trip we didn't actually fly to elky texas we uh we drove down uh took a few days stayed
at a friend stayed at her friend's place he came with us but it was a good trip we ended up we saw a lot of a lot of
america's heartland in the process that's right this is the t-shirt oh that i look
forward to that that's a beautiful shirt sorry er getting lost in the universe yeah yes
no we could but i can see for the most part um whether or not i can actually play is a
different matter um i'll have to continue to work on my work
on my weight loss goals but i'm sure that would uh i'll take whatever shirts are offered
so right now no no yeah if you have 2xl though that would

uh we have uh well let me just kind of go through the list of people we're watching today we have
harold locke uh martin eastburn tarreck was watching from the uae
jeff wise um billy's astro was watching scentil
nagapan was watching um we had um
uh let's see gary alban uh who's uh wanting to go down to winter
star party we um uh before we always knew him as book davies
his real name is steve he was watching uh um
and uh let's see who else a lot of they're all talking to each other
uh friend friend kaido zhong is was watching um
on too many people tonight yeah yeah i'm only through half of the list so there's a lot of people here thank you all for
watching and participating and asking questions and chatting with each other that's what it's all about this is a
this is a star party for sure exactly well good night everyone
tonight what i want to show you is some things that i've been doing this couple
days ago first of all the last gsp i was doing a
live view with the the camera and the equipment outside and when
was we were talking i was doing pictures of a 47 to canada
and then i process and and i get this that
that night
yeah that's a beautiful globular cluster i think there was only 20 minutes of
taking pictures of one minute you know yeah too much because there are the they are
all stars so yeah and also you have to prevent to
to get very brightening the the car because the core exactly
it will get it will get very white so well
uh that that was last tuesday and the the fri sorry the saturday i
i well i have some three days from work that saturday i didn't want because i
have one day of holiday i left so i i want to do some
solar pictures and put the equipment outside very early it
was maybe 12 p.m 1 p.m and
well i grab it you know it's very at the
midday and i was doing well he's the notebook covered with a box of cartons
mission control right there maxie mission control exactly and i was you know because i
can't see anything for the the shining sun i was doing the uh
working with any desk a controlling inside in my in here in my
home and and taking some videos and well uh you know
we have in this days uh some kind of solar activity
and we have the the dark the the
the sunspot um that the two two eight eight two this is the
principle and now it's going to the to the border of the the sun
but uh this is what i get that midday
with this scope and of course a solar filter a water solar filter
and here's the principal
dark spot and also a couple more very near
also this region has some kind of dark spots
but i i love when i see the at the edge of the
the sun this uh whites or more uh brightening places it it looks like some
a ladder of course this is plasma but uh
i don't know it's like it's getting um
a cover out i don't know it's like a broken egg something like that
and i i i don't know what i love to see that this oh right yeah these places sure and and
in this case they are in a very very places of the sun
so that day well my wife say oh you are going to with the telekopo we
we went to to have a lunch
outside in a place called choripaso it's a place where you go if you're traveling
uh you stop and eat some choripan and
or some sandwich with meat or something like that
and well then we went to [Music] because i want to to teach teach her how
to drive the car and we went to a a a farm town called um
sorry ramon diaz it is that's what how's it called
and we it's been taking matters that
evening and well this is my car this is a very farm area this is in a in
an abandoned station but maybe i don't know 40 or 50 years ago
the train passing by from here but right now it's it doesn't but
they this town is very quite very calm and
they have this amazing view of the sky in in the middle of the of the town
and well the streets are from like this no it doesn't exist the
the the the asphalt the payment exactly and
but you know i like i like how it looked like because they have of
course some old structures from very old 100 years of construction
but also a new houses and that is
very colored place and and quite i remember i saw um
a firestone place they well they have the the fuel
bombs pumps i don't know how to where you they
put your fuel yes exactly and they are very oxidative but very old
they still have firestone put in there because it was a a place to change their
wheels and then near of there is the
this river that calls a salty river or rio salado
is a very quiet place where people go to to fishing and
and also you can see this view on this case it was the
the at the of the afternoon and the sun was
downing and you know i i told her i need to take pictures of that because i want to do
some nature pictures you know in this place you can see a bird
it was uh in there and also well the fishes was i
don't know the words champion but the river is getting dry
uh it's maybe the season but it was very low from another sunday i
went there and this is another picture maybe a dream
do you like it yeah no it's a great picture you only if that's not a bird that's flying
towards it um then and that might be a bird there
it's a it's a bird it's a bird yeah there it is there's the wings the big bird
yeah yes yeah no it's a beautiful it's a beautiful picture that you got the sun
of course your camera you know you see it a lot brighter like
that you typically see it a little brighter um your camera you had a lot of birds flying around too
but um yes you do have some of the sensor dust but that that happened like i i tried to
clean it up but i i couldn't uh so well then
i remember see this sunset and then the moon was a i think you called
waxing right a waxing moon when it's growing yeah uh the growing waxing moon
it explodes the sun into the ground yeah and also you can see venus and because of that it was
jupiter it was like this is the sky it was a
very huge perspective so when i get home i
i have my equipment outside and i say okay i had to of course take pictures to her to the moon
so i only did 20 pictures with a single
picture with the camera in with the cwo and when i started i did some grizzly
1.5 the my computer was up very
in the point to explode but
you can see too many places uh i i love when the the
the the characters it comes comes up i don't like they see the moon when it's
full you know i i i really don't enjoy it because
you have too many irregular places and craters and what
it's you can see maybe 100 kilometers or maybe more and
it's like a little circle but it's a huge place and also deep for example
that's huge so well when the moon starting to go
out i started to to one i i was getting to the my
neighborhood because they started to to start the fire for a barbecue and i
don't know really upset yeah they gotta block that the barbecue itself is fine but the uh
light from the fire no the smoke is the also the even worse
yeah exactly and also another neighborhood
turns up the his backyard lives and
it was like morning but well i
was trying to do some pictures of the dumbbell nebula this is only
a dbe well i think gary is here
he he knows what it is and i this is what i get when i get
stretched and i'm 27
and 27 except the dumbbells nice
i i i i didn't process this i i think i did maybe
one half an hour maybe stuck in doing pictures of three minutes
but i didn't process this yet i only
put up the the dynamic background extraction and well i had to to still working on
and was when i i realized that it was getting low from
because i haven't to the north uh passing by the the meridian
uh to the northwest and then starting to go very low so i have to say okay that's it i can't take
any more pictures from there and also i was the more later starting to
to er
upset from the clouds because i remember was inside watching a movie with my girlfriend
and you know i i heard that alarm
constantly and i thought that was in the movie but she said no it isn't the movie
exactly from the phd software and oh no i had to stop and now i don't
know how no it was awful so i wait uh more later and i remember to
to talk with cesar uh to chat with him and
it was saturday night we have nothing to do what's four a.m saturday
night when i returned yes when i returned from from
observatory only at 12 past 30 past 12
and say okay this is great to go to sleep or maybe i can start to
to process a computer the pictures that and another
picture with the pixel with the notebook inside with a precise tags or auto stack
and say okay hi maxi how are you and we started to talk
and and also you know i was
processing and seeing what i was capturing that time and and i need some
kind of company and of course well cesar is up so let's talk with him
yeah [Music] so i went to m42 i just today i
finally get the the process image but i really don't like it too much but i
have to be working on this is the picture that i took of m42
this is what i have processed and nice you know i think i will have the
with the stars uh some reflection but no you know uh
it's a good thing i guess and also
exactly and i thought maybe well i was practicing with m42 again because i don't want to
to burn the the core but i think it's a little bit but the structure air surrounded
is it's allowed to see it but like i said the night it wasn't
a great night i remember it i have um well here in chicago we have still a
mercury light it was very orange and i have only a descended a
some kind of dark circle small and everything was very orange and white
from the red slides and now it was awful and
well then when i tried to do some things because i want
to see how uh works the camera and the field of view
i went to m 78 i think it calls and
it's also in the orion nebula but you know the the light pollution and
i think the clouds also or something clouds uh
they bother me look how much dark nebulosity it looks like two eyes are sticking out of the
uh out of a cave or something exactly but i really like this place
this is beautiful this place from here because they have
stuff but it's like when you when you see the moon through the the
clouds or something like that when you see that that kind of light you know uh
you know there is something behind it yes
mysterious exactly exactly and also this
places here that have a reflection from the stars but also the
darkness velocity is amazing so uh
days before of this i i tried well i put my equipment outside
it was a clean night everything but when uh
the the place that i want to to take i started to to comes up
the clouds say me they put your grub inside again and go to sleep so
i was really upset because i want to capture the 67p comment
the two most but i don't remember the russian name of
that comment but because it was passing by very near from
the m1 the crab nebula and i want to do some
uh two pictures of that place that night and now the
the clouds doesn't allow me so this saturday night
i was able to capture it i only did a
23 minutes of one minute
pictures and you can see here is the 67 comment
oh yeah and also it has a little say i was i'm still practicing of a stacking from a
place a the comet and the in another image the the stars and then put it
together but some kind sometimes the background goes very
weird here's for example the the stars the brightening stars have a little
shadow from the down but that's why because from the stacking
a comet only a well i don't know how to say uh
grabs the that light of the stars uh so well i want to show you this kind of
um well a blink well it's like a recording
this is all the the frames that i took that night and this is an animation to see
a how a very fa how moves this comment is very
very fast yeah we i can put the the
emotion and
you can see how moves yeah this is only 23 minutes
uh when you stack this when you stack all the stars in the the
the way of always uh it's the comments it would be
in all this place uh stacked so uh
this was maybe i think it was three yeah yes uh it's still very down
because for the light pollution and also the guy was awful but allows me to still
taking pictures and still practicing so what i think that's all yes i show you
yes uh that's what i was been doing uh this saturday i was a
santiago mayes from caesar invited me to
the the star party that they will do in the vista bell but my professor of physics here
um asked me a a month ago if i
i was able to do some some views of the moon because it was it
would be the international international moon
view or something like that so he wants to [Music]
so well um to he invites me to be there but i i can
be in both places so the next month i will be with caesar and that's why
i i i think i will i will bring my equipment so let's see
what happens so thank you everybody yeah well let's continue
the after party yes okay so yeah like uh we'll take a short break guys um
and be back in a few more minutes and uh we'll we'll uh uh convene on the after
party here okay excellent that's exciting good so unfortunately it's about midnight
here so uh hopefully folks join you all for the after party
um i am going to head up uh and grab some sleep after my long trip
um this has been very enjoyable it's good seeing you all again
thanks i just i thank you yep i uploaded some of the data i found
so there's so many other pictures i'm going to find that i took from the uh
from the okietek star party so you saw you saw one of the other close-ups i didn't even know i had
and so there's uh i also have images to start stacking so
there's gonna be some work on the computer to uh see what i got here but uh
yeah that's coming up you have too much to to working on yeah
it's all good to have too much yeah yes here in this same in the states
we have we say a lot and when we say too much then it's it's more than we can handle but uh
no it's uh too much for too much is a good thing i even got data
another person handed me a usb stick with uh even more data to see what i could come
up with maybe i should send it to uh gary or one of you maxie and say here
use pixel sight on it and see what you can come up with he had some wide field uh views
some good some nice sharp wide field view data and wanted to see what i could do so
i'll play around with it as well but uh but i am going to take off i
my camera finally working the one that i want to use with my setup on the computer is finally
working so hopefully it can keep going it's it's the camera that can zoom in and out so i
can get a good close-up picture a closer picture of myself with this so
hopefully that will continue and uh that i can use this instead of the little wide
small cam that doesn't work or yeah don't like it anyway
but uh yep i see uh jeff and a few other people thank terrek
um thank you all for the comments i see it and um
i will go ahead and head out you guys
yeah i'll see you two gentlemen in the near future
okay man all right take care we'll be in touch yeah
good night yeah
so i think it's only you and me cesaro what i don't know
in spanish do you want [Laughter] poor people if you
if you start to talk in spanish in our spanish that is sadly this
with a people say no no [Laughter]
we talk too much we talk very fast and our spanish is not
not spanish
well we have some kinds of little words in arabic i think yes
yeah well i yes we we finished the last time to 4am
but i promised tonight to to finish to go to sleep in 15 minutes
then the two by the way and me
[Laughter] yeah now i
that is it's amazing your your picture of the comet max he is
yeah i remember for me was amazing that i accompanied you
in the in the little mode yeah yes i and you you too to me because
the process of jupiter was uh great in the in the morning i say okay i try
to i try to to put in in sequence equator sorry um
out stacker i put a 1.5 bristles let me say okay and you prepare
because yes my computer can explode too um and
i couldn't see some difference i don't know why
i made two kinds of different uh process one only with the video point dot iv
pointing pointing only
in the in the pixel cycle but since i know in the rec
tax program we we say a job with friends
that are astronomers amateur swimmers like us that will say oh these
um they use really they use over his tax yes i have my biscuit
from 1996 i made a show that because the joke is that never
was um maybe the last the last uh
edition of practice taxes from three or four years i keep this from
2016. and but it's still working very well because
i put the video of the who picker great to say i only move the wavelets a
little and i i of course i i
i used a mix of your
conceptuals advisors devices and devices or and advices
[Music] a mix because the problem is that we are
using the big size uh pixel galaxies
were regarded as island universes isolated realms of gas
dust and billions of star that were separated by distances unimaginably fast
but no galaxy is an island in fact galaxies prefer company
the gravitational pull of a large massive galaxy attracts like-sized and smaller neighbors
galaxies may gather in modest groupings like these or congregate by the hundreds in
enormous clusters this is a bill 1689 one of the largest
galaxy clusters known this view spans some two million light years or about the distance between our
milky way galaxy and the nearest big spiral into the space a bill 1689 packs more
than 500 galaxies as astronomers mapped nearby galaxy
clusters a more complete picture of cosmic structure emerged
galaxy clusters gather in super clusters and overlapping superclusters form
chains and filaments spanning huge swaths of the sky
welcome to the cosmic web this all-sky map shows structures
created by more than a million nearby galaxies deeper studies show that this pattern
continues to even greater distances the cosmic web appears to be the
backbone of our universe
the universe came into being 13.7 billion years ago
about 400 000 years later it had cooled enough to form the first atoms the event
created a sudden pulse of light that astronomers now measure as the cosmic microwave background
but then the universe went dark for millions of years
eventually hydrogen gas cooled enough to collapse and formed the first stars
these stars not only re-illuminated the universe they became the seeds of all
future cosmic structure the james webb space telescope may be
able to see clusters of these first stars
it may even catch a few of them dying in supernova explosions
either the first stars or their progeny gathered into the first galaxies
these were small gas-rich dwarfs nothing as grand as the big galaxies we see
today but they were the building blocks of modern galaxies
as the dwarf galaxies form collide and merge into bigger galaxies
the cosmic web begins to take shape with the james webb space telescope
astronomers will glimpse the earliest phases of construction that led to the universe we know
[Music]
well is it just you and me maxie no i think he says he's here too
hey questo
no no sorry uh we was talking um what a kind of fun to
talk in the after party yes
well tomorrow will be lunch the
i think that is the blue origin yes uh the region blue region yes
majesty yes it will be tomorrow right yes
who's flying on blue origin this time the blue region yes
william shatner right he's yeah we're in chattanooga yes it's amazing
yes yes maybe you you watch the
is it fake but it's so so amazing that somebody turned the colors and the
design of of the jackets of the of the member of the crew okay the crew members
to the enterprise now with the colors of the captain
kirk i say it's it was amazing for me was you i'm so nervous i i i know i think uh
well it will be traveling with the in in scene well the
lunch with that so yeah yeah for for the fans is something
apex something epic yeah yes i think that that is
something historic because it of course that is the time the the age of of the
of the civil uh the civil flight to the space and
i i saw the in the netflix the the last uh
documentary of uh i think that should that shut down
maybe the name of of the documentary puente regression in spanish but i think
that sometime i turn my netflix to english or spanish i i don't remember the name of the the titles of the series
or the movies you know and i think that this should shoot down um
[Music] it's very the history of this this four
crews is amazing it's very very the history of of of the girl that is
actually uh she's medic and she's doctor in in in the same hospital
that saved her life it's it was very inspiring history and i
think that these four guys that they went to the space and
they lived uh three days in the or within the
health it's it's it is it's a it's a this is magic and um
i i think really the people today see this documentary because they say
it's incredible i couldn't i couldn't stop this story
sorry maxi i i know
because you you have before or before the the lounge you have to watch
in netflix the the this documentary to know the people for
me i i thought no i i cannot say i cannot watch this
only uh because if i just i will start to know the people that is going to the space is
something going wrong you know because i watched the the
challenger and the uh live tv and for me was something
um you're not just got that it was for our generation was something like ah
terrible because we had an aspect of of the idea of or
in the time of the channel yeah the gentles that
and for me it was impossible to to start to watch this program and say
okay i can see that only if they return is safe and
safe safely and i can i need to watch the show because if not this is possible
to me because i have i've had an idea of the the people going
to the space and something is wrong because my my fear was remembering
the the challenge oh yeah yeah yeah yeah the colombia and the colombia
yes yeah yes yes you know yeah that's right
and now you remember too apollo one you know when they were whoa
yeah you know so these yes the job that they're doing is dangerous and it's also dangerous
for tourists you know but sure you know uh also diving very deep and
the ocean is dangerous and skiing uh tall mountains dangerous and
getting on your freeway and driving to to your work is dangerous yeah
absolutely living in argentina everybody's like oh okay there's okay
but if they go on a spacecraft okay and there's a fatality somehow it's worse i don't know why
yeah but there's a lot of um i think part of it is there's a lot of hope
and uh uh we project um uh the
you know our our feeling of their adventure you know uh is it goes with it and um
and we know it's dangerous you know all for every minute until they're back down and
and the the mission is over right there's there's uh so it was um
really interesting when i was able to spend time with buzz aldrin and we were talking about
uh his mission on apollo 11
i had read i told him i i said i had read that um that
you guys only had a 50 50 chance of making it back he says
he says they weren't giving us he said that's what they told the public he said really what it was is they had a much
smaller chance of success okay oh much smaller chance than 55. oh yeah and
i said so i said did you think that you weren't coming back and he said no he said i knew i was
coming back you know so and that's why they still going and
because your mind maybe if you start to think about it but
it it's like you say it's very risk risking it's pretty risky oh yeah
absolutely yeah but you know we we live uh being alive is yeah being alive is risky
yeah yeah so um you know a lot of
you know i've i've been asked i've asked myself many times would i go
if i had the chance yeah i would go i would go you know yeah i would love to see the earth from space
you know like that so yes i choose yes i i'll go absolutely i
i think the tickets they cost 100 million dollars
okay okay we need to sell that no problem okay so so here here's harold harold
lock he says as a truck driver i had to avoid and think fast to avoid being
killed at least once or twice a week if it wasn't for a constant because la
traffic is is insane or yes that's true it is our plan is
aries or london or you know everywhere world's in argentina
yes yeah yes um something that you tell about the diving it's something that all people
say okay they've been safe but it's first of all it's something that you
went to another another space that is water
and another planet one minute yes you feel like another planet for me
i i remember that that i died at the 20 meters at night for example in a
in a dumber lake in san grace here in argentina or you say come on without i remember that i
started to die when the the life jacket that the company that actually we use and we change and
change the the your level without swimming we we use that
we started diving in the end of the 80s without treats because the street was
started in the in the the first time of the 90s and i remember today they say come on it was
crazy because i i have only my compensation with with
the the counterweights in my belt yeah
no no jacket no my kids say so you didn't have the inflation
and you calculate you remember that and when you went down
maybe you was more able to to go more down because the
your skin sweet yeah yeah we're living with low pressure
yeah that is sweet sorry yes come on and we started with that and
when this is a little thing comparing with the people that go to the space
especially when the the walking horses have the same sport
space walking space walking the lane yeah they are they're they're a
spacecraft when they're out there yes yes and it's the opposite
in the water you have pressure when you go more down you you start to feel it
but i in this place
because yes absolutely yes yeah no i um uh once i was at a science show
and they had the trainer for uh
for astronauts he was from russia he was a former cosmonaut i guess and
his job was to train astronauts on what to do if they are hit by the
small pieces of um of junk space junk in space like you know like the the bolts
and the he said there's a lot of this stuff out there it's flying at unbelievable speeds you know faster than
a bullet okay and he said that i said so what do you do if you get hit by this you know
you're he said if you if you can he says you have about you have about two seconds okay and what
you're supposed to do is take your thumbs because it's probably going to pass
right through you okay and you jam one thumb into one opening and jam the other thumb into there and
then the vacuum of space will seal around your thumb
no in around your thumb so you don't bleed out okay and then they need to get you back into
the spacecraft this is insane it's so easy yeah
no no no it's incredible come on yeah we need thinking yeah and these
people think that this is possible and it's real and it's i remember saw a documentary
i think nasa was a practicing with a space suit
in a vacuum a huge vacuum chamber and it was recording that
the the person that was uh doing the the practicing has the the the suit uh i don't remember
what happens that they he start to to
to go sleeping and gets to the ground because it has a
little infiltration that the air it was passing
it will go out and the the his blood it starts boiling
yeah the worst part is that and i think
they realize that how much maybe you feel well if you have
if you don't have atmosphere uh or a thin atmosphere that we have
here but uh now i it's very
i think it would be horrible to feel that yeah
like the bends they call it the bends and this is what divers get my father my father was a hard
you wore the hard hat deep-seated okay and um
yeah he experienced people that uh they came up too fast okay and then they had
to be put into the chamber to you know to survive and uh he said
some people they could never they could never equalize them
you know they they could live in the chamber but that's the only place they could live okay yes yes absolutely yeah
yeah yeah yeah so they could never compress that all the way to normal and
only people that only can walk in the chamber vacuum chamber
uh or um it's not back on chamber so how do you say that uh
to the chamber in this yeah it's a it's a pressure chamber it's
what it is pressure chamber yes yes i i i was in one i was in one to oh really yeah to
learn yeah yes only to learn but i i suspect that they have uh
a small blend in in the in the shoulder it's called the hyperbaric
hyper heparic cavity yeah
yes yes for me was was very interesting the
first my first
learning to dive in this time in the 80s um
i remember that we visited um we went to the inside the barbaric
chamber and we inflate a balloon only little and we
swatched how the balloon starts to start to
drink or express the whole story no yes we yeah we fly completely and we start
to watch all the balloons going uh smaller and smaller are
like without pressure um yes maybe we we went one hour i remember
and i the the things of the blends is are so real that
i suspect that i had one because in brazil i lose
my my counterweights belt i go to the surface
come on no it was impossible to me to yes stop to go to the yes first of
all i remember i returned to the sixth meter i i make uh
we call it this compression i think that is
maybe this curve until pressure
to resolve something of this six meter three meters and go outside
but in in in few in in two times later uh
in different times that i i took a fly
you know i felt pain in this area
oh because uh when i start talking with people with divers or
doctors that know about diversity maybe you had a little pants because
it's it's really normal that you have something and maybe you lost with the time that
because yes uh in two years more i never
felt in a fly uh some pain
but the the bubbles in the blood are really really dangerous dangerous yes
yeah but it's but many people say the same because these are
small bubbles inside the muscles inside the articulation and this is why
uh for example for older divers in the past they can't they can work
only they can work diving with the you know
with the same kind of dive streets like the helmet
i don't know the helmet is the name spot or yeah helmet that they've helped
in the museum of the the navy from here from argentina they have of course too much of uh
the guys hanging with chains
that a diving helmet and you can put it inside and you feel that you know
i don't know how many how many pounds no it's really heavy it's really really
heavy and you you see only this circle and ins and
the other side and i don't know how to and
for example in argentina the waters they are not very clean because we have
some a mix from the river and have a very brown waters uh
yeah so yeah i don't know how they touch what they have to touch and that's it
maybe it's a rock maybe it's a fish i don't know but they couldn't see anything
yeah so uh during one exercise on a ship
you know the navy guys with the with these diving suits they practiced a lot on different things and uh
uh one of them was uh salvaging an old ship okay that was had a lot of mud
inside okay so they had to have these big hoses that they were putting
inside the ship to to vacuum out the mud and then and then
what they do once they have all the mud out then they uh they flow air inside the ship and
then it raises up okay that's how they do ship recoveries um
anyways he's down there sucking the mud out and the hose breaks
and what comes flying out is all this mud and he's buried alive okay
buried alive in his suit he's got the he's got the air still coming down to him they can still talk to him
but he could not move and there's no light okay so it's like
complete darkness he had to stay down there because uh he had to stay down there for like five
hours because they had emergency vehicles that were they were a couple
you know they were like a couple of hours or whatever out from base and they had to get the equipment and everything
to come back out and dig him out and everything which they did they got him out
but once he got back on the ship they said okay put on your suit go back down again
right away oh no he said he said that that's to help the psychological
effect of being buried alive like that you know
no no immediately again yeah i believe you that is great it is training so hard so
hard that is yeah because this these guys uh for example here as maxis says
here in our river rio de la plata the
yes once at once a time i tried in the delta with friends to
to make to make a diving only to try and was
absolutely black the under what yeah
[Laughter] this is in the museum of the navy in
marvel holidays
but this is something that we are talking about the two different space no water and vacuum and space real
space
[Music]
the subject the subject of that we are talking uh
for me it's incredible because uh from last saturday to next saturday that we
will have a an astronomical event for for us it's impressive because
uh we have the well we have something like like a
fire in the one month ago
we are making last next saturday this is february in november i don't
know what which one of the weekend the third party
for amateur astronomers and the last one i think that is
december 12 that is the the last uh the last uh surprise
of the year in in observatory and we are i
uh i i although we i'll be go to uh san juan observatory caglio
uh to make a star party with eric gonzalez with the san juan government
this will be maybe in the end of february and
our mainstream party uh san rafael uh
star party in uh one two three and maybe four
of april in 2000 but next year of course
okay i i have this is the the yes give me the dates because well
finally february maybe i will have the holiday i don't know yet
and i don't know where we if we go home in holiday but maybe we go to san luis
from my my but the the apartment of my parents and
we are maybe i don't know 300 kilometers maybe a little more but
you know we'll be in a very good sky so maybe i can of course save that one week
for that and then maybe for for april i don't know i have to talk april
yeah april is is the main surprise because it's our i don't know how many
star parties in san rafael who made with hayem garcia but is is
maybe from 2004. i i made it so paris from 1996.
uh yes it's like a couple years
yeah yes first one was 24 1996 was the
second one and we made uh investor and this year in that year we made a
winter and summer edition and we started to make was uh
a lot of different parties but in
2004 we changed from from buenos aires
farm area only 500 100 100 kilometers 60 miles
from the city we changed to san rafael because we had a milky way over our
heads and big hotels hotels for for the uh
for the people and make the star party inside the hotel very dark it was
our best uh uh best solution to have a safe place
nice nice to have you know you know your room
you have your rooms yeah yes actually we can
we can get uh you can get your telescope outside because we are
using the uh beautiful terrace yeah that is excellent to to to put the
telescope and don't touch in the three days that you have
yes because we have absolutely all and you can go
uh to your room only 20 meters very very nice that's nice
and yes yes we we choose the the
first of all we start to think first of all we can turn
off the lights of the entire area
the for example the one kilometers where
of the road that coming from the main road to the hotel
they had uh electric leds illumination we can turn that
we can turn the entire system off of the light of course
really dark really really the only thing that we you can see is the city at
maybe 50 kilometers of san rafael but this is not a big city it's normal right
and here like a small dome yeah and as uh you have maybe
uh 25 25 of humid uh
in the air you know it's it's like arizona is
yeah and maybe you have a city but is you don't have dust or humidity there
um really so the dome is not very big and uh absolutely yeah yes yes and it's a
mix between maybe you we can go more to the mountains and have a more darker uh
skies but something like this that you put the telescope and if you like
you can left the telescope outside you can put the cover you know
it's really we start to say okay the people need something uh that com
more comfortable sure have a strong amount that's right and they say it's okay because
i remember in another parties the people go more
outside and we need a lot of tables to to bring him to breathe
them and people say no but i'm not sure and
yes i'm carrying again the telescope at the end of the night night
now we it's funny because we can use the telescope i say okay you can get the
telescope here no problem it's safe it's really safe you don't have any problem
um and we can go to to the barbecue
eat uh teresa's or blah blah blah all that you and you can go to sleep
without the pro only off your computer maybe your computer
you can you can you can get to the to the room of course
but the telescope with the cover say okay or the moment if you if you
feel a little scary you know but uh
this is was this was some years ago the change
of the comfort's ability to make astronomy in the surface um
i saw united states that the people don't uh disassembling the telescope in the
three or four nights that is right no it is real
in the third parties in the united states the people say put the telescope and only when they
go disassembling uh yes it's the best way it's the best way
you're right that's right yeah and the comfort but having a more comfortable star party have facilities
bathrooms something to eat someplace to go to sleep these kinds of things are very um
it's it's nice and you may not be in the super dark area but uh
but it's the facility you're describing sounds excellent so
yeah come for the table yes yeah like our our first
uh sense was come on the people need to to
to feel a very comfortable about use their telescope
and my photography and when they need to go to sleep
only for the covering in exist uh
an excellent in argentina maybe the best cover
to put the telescope is the same color that you do use for
motorcycles um are the best way
if you know if you of course that if you have the security
that you can get a storm in the night because you you
for for us like your organization say okay we don't have any any
uh advice of storming or very uh strong wide winds in the in the
in the night of course sometimes if we are thinking about
strong winds we can talk with the people say okay
carry your chest the tubes the optical tube assembly inside to the room or put
in the lobby normally the people put in the lobby of the of the hotel no problem
yeah when you can go in the morning you can put outside again
or if you like you can you can left the complete telescope
computer studio if you have something to cover that oh it's safe it's safe out
there and yeah yes it's because the the place is
safe for for that's good that's great yes
yeah i want to go i ain't thinking that i i can i can wait okay yes
i want to go sure yeah i think that maxi
maxi i i really want to go with two i really wanna
all right gentlemen well it is midnight it's one minute yes it's the best yeah
