Global Star Party 42

Transcript:

from the internet and the router is just right under my desk so it's really nice
oh there you go all right and I see your your cat is uh in the back there that's
nice yeah my friend gave me a Galaxy doll doll bed and I didn't really have
any dolls so I put my cat on it and
she that's great
so how about uh uh have you done any observ observing lately Libby or have
you uh gone out with your telescopes in the last couple of weeks yes I did last
night because we had a full week of clouds and snow and rain and it was just
really bad weather I had the telescopes out so I had all my telescopes inside and then last night I took them all out
and I taught my mom how to use a Gallos scope because she didn't know and she
looked at the mo for the Yos scope um and all my telescopes out in my
Observatory tent so isn't it fun to try out different Scopes it must be nice
because you can look at different things right uh so with are you finding that
you're using certain telescopes for different um different objects or um I usually use my um I haven't used
my doonium for Saturn and Jupiter yet and usually I use my new tonians for
that um just because it's a little bit easier because I haven't tried it yet on my doonium which I need to try and last
night I tried my 6.4 lens on the moon and I haven't tried and I didn't try
that in like a while and it was amazing so I'm really good with newtonians and
I'm learning a lot more about my dog sonian the more I use it yeah it's it's really neat you know
what's really nice is as you as you get more experience with using the telescopes you you'll find uh some
really nice uh you know for example like you say I mean you you don't normally think of using a dobsonian for planets
but boy oh boy uh when you do you're going to really love the view I can tell
you that you let it cool down you look at Saturn or something you'll be amazed it is so the colors are much more
vibrant contrast and and very sharp it gives you really good resolution you'll be
you'll really enjoy
it or maybe not then you go into another field like uh stock market or something
like that never you just got I don't think the way you're shaking your head I
think you've chosen your your field and I'm proud of you liby that's
awesome that's awesome so David you you were um you were actually uh
there was a couple times where you were actually out there in in your field you're in Arizona right I am in Arizona
Southern Arizona I was out watching lyds last night I got six very faint
ones and uh it's kind of kind of fun but uh when on the maximum on Wednesday
there'll be almost a full moon so don't think I'll be able to see any then but or maybe but um I can the meteors that's
my favorite area of observing oh yeah is
comments the other night I was just looking uh you know when I was doing my survey I just glanced up and I saw a
point meter meteor that was really neat um where where it just comes straight at you right you see flash yeah that's kind
of cool yeah yeah po meteors po meteors are illegal in Ariz
Southern Arizona illegal see one here you can get a
ticket yeah
yeah and then Scott you were saying you you just like you're right beside Libya
you were getting some weather how is it looking uh tonight or or in the the rest
of the week well um of course the night after F
of observing we got almost two inches of snow and wow last night when I was
observing usually during the night time it's a little bit more colder um because the sun's not out it was 60 degrees and
it was really sunny yesterday and it was hot and then today we've got two almost
two inches of snow and we had cover all of our new flowers
and everything oh yeah that's true that's that's that's the I mean it's it's
pretty but on the other hand it's uh if it gets a little heavy it's kind of uh
is hard on the flowers that's true well hopefully it it sublimes and it uh melts away quickly and then it'll be
good yes it is melting right now so where I live climate change is huge
because the other day it was hot and then now it's cold and then now it's going to be hot again tomorrow and then
rainy and rainy yeah yeah okay yeah it's uh
hopefully um it gets more stable as we as we get into to May yeah here in
Seattle uh we've been having a very unusual uh incredibly
clear uh Skies that's how I was able to beg I got over 500 Galaxy I would say in
the last week um just I I just like I say I just you know how intimidating it
is when you when you start to dive into like you know coma brus can van and and
Virgo is just like a swarm of galaxies so it's like okay well how do you do this right and uh I I just methodically
went through it and I took one constellation at a time Virgo took me three nights actually um and uh but I
but but just like I say just in incredible weather uh you know I have to say I haven't seen it so good it seeing
was probably two uh for you know on the average and um yeah so it was it was
quite quite nice and of course to top it all off I had the uh the moon the new moon as well
so hey Adrian I like your background dude thank
you hello Adrian good to see you hello Adrian Adrian
hey I am looking for the
um button that'll allow me to change my view but I think I think I'm uh it's
because we're broadcasting the uh two minutes to start so I have to scroll to
see all of you uh can I get a sound check real quick can everybody hear me yeah
David and all the only one that are I'm not hearing very well is unfortunately
Libby uh hello even she's a little better than it
was it's still almost impossible to hear her hello DT hello from
Nepal well we'll do I guess we'll do the best we can with
um with what we have mhm I'll uh I'll be
watching we have pretty good
yeah yeah I'm uh pretty good in the middle of another there's another Zoom
meeting going on but I'll probably just drop that one and uh stay on this one
I'm actually using two devices at one once which is pretty
[Music] cool oh and uh and uh
David the your favorite tree I've I've gone out and taken a couple of pictures
of it oh wonderful yes yeah I'll uh I'll shoot you an email with a couple of
images I have yesterday it was 60 and raining today it was snowing so I took
some identical shots with the different weather uh featuring that tree so you'll you'll get an email
soon and one of these days I'd like to see that tree in person that um winter is the best time
winter is the best time because you can walk up to the tree the farmer plants
during uh spring and summer and so I you walking through his crops probably not a
good idea but during winter when everything's covered
with snow that's when I walked right up right up to it so uh you will I will
I'll send you I'll make a gallery and I will make sure to send you the gallery
and one of my my favorite tree thanks I had been looking to photograph
it for um maybe a couple of years before I finally
did good for you Adan
David and I talked a little bit about the squirrel after you left
[Music]
yeah on January 9th 2020 NASA's Lucy mission team revealed that the
spacecraft would be visiting not seven asteroids of this plant but eight as it turns out Ides one of the Trojan
asteroids along Lucy's path has a small satellite or Moonlight orbiting it finding these tiny new worlds before
Lucy is launched in 2021 means that the team can investigate their orbits and plan for more detailed followup
observations during flybys Dr Keith null and other Lucy signs team members have
been using the hble Space Telescope to search for satellites and rings around Lucy's Targets this can be challenging
since the raw images are often filled with bumps blobs and defraction spikes the Lucy team didn't see any evidence of
a new satellite until November 2019 after experimenting with the brightness and contrast on the H images Dr saw a PE
faint SP ues Dr Mike Brown another team member noticed the spot showed up in a
slightly different position on another set of H images taken two days later this change suggested that the spot was
an orbiting Sal the team went back to Hubble and got three more chances to make observations of the Poss sading on
the first two tries the little moonlet was nowhere to be found but on the third observation on January 3rd 2020 they
found the possible new satellite again it was clearly visible next to Ides which was over 6,000 times brighter this
huge difference in brightness suggests that the satellite is less than 1 km in diameter very small compared to Ides at
64 km with a few more Hubble observations the team pinned down the new satellite's orbit and they proposed
a name International astronomical unit approved and from now on the little satellite will be known as K after enria
Bas the first woman to like the Olympic C evidence indicates that the Trojan asteroid deres is the largest fragment
from a massive asteroid Collision that happened billions of years ago it is possible that the new satellite ketta is
a remnant of that catastrophic event whether with Hub or the Lucy spacecrafts flyby each observation enriches our
understanding about the Trojan asteroids formation and U's relationship with its newly discovered companion the discovery
of this new moon around the Trojan asteroid arities is just a preview of The Incredible scientific knowledge that
will be captured by the luy mission as it explores this area of our solar
[Music]
system well hello everybody this is Scott Roberts from explore scientific
and the explore Alliance and this is our 42nd Global Star Party um so excited to
be back here with you guys uh to do this we we did the 41st just on Friday and uh
uh so it's been um it's been amazing it's been fun uh you know when I look
back on all the amazing people that have participated on global star party uh
both in the audience and and the speakers and presenters uh you know we
have covered a a a universe of amazing
subjects and and imaging and topics and uh and I think we're just getting
started really so uh uh we um so I you
know I'm I'm deeply honored uh to um uh be able to uh participa in this and to
you know be able to do what we can't do to bring this to you and so um uh our um
our first up as as always has been uh is David Levy uh David is uh you know uh a
someone that uh uh really just gives us so much inspiration uh you know I've
heard it from the audience I I hear it from uh the people that are uh
presenting with us you know uh for many of the people in that that are
presenters here they go you know they're just it's like being on stage with like your your
you know favorite celebrity or something you know it's it's uh it is really
amazing and um uh you know a lot of us uh if it would be our first time to do
something like that with David or David Iker or any of these people uh you might
be a little bit nervous okay but uh and I could say that there was certainly a once upon a time I would be too but they
make it nice they make it uh they make it a pleasure and uh and you realize
that they're there there to be uh not only to share and to interact with you but to be your friend and so I think
that's really important I think that characterizes uh the the amateur astronomical community at large and um
so anyways I could go on and on about those kinds of things but I'm going to go ahead and give the stage over to
David Levy um David thank you for for coming on once again yet for the 42nd
Global Star Party well thank you Scotty and it's really an honor and a privilege to be here we have
several thousand people around the world tonight and what I have to tell all of
you several thousand people is that I don't believe there is one of you not one who either has lost a parent at some
point or will be losing a parent or a grandparent at some point even our next
Generation Libby is going to have that sometime in her life and I hope that that doesn't happen for a very very very
long time but uh I think some of us have already have talked about these personal
losses that of effect and how the night sky has helped us go through these
losses I remember when I lost my father from Alzheimer's disease I went outside
just went outside quietly and looked up at the night sky and uh M I didn't even know what I was looking at I just stared
I just stared and stared and could never really stop just staring at the night
sky and I know that Scotty has just had a lot a loss very very recently and I'm
hoping that the night sky will help you and give you some comfort as well David when I think of the fun that
you and your dad have had talking about the Civil War coming to on and watching
Lincoln I will never forget that experience with you and uh the fun that
you had with him and uh when you gave your talk about him a few weeks ago it
was just so special to hear that anyway I uh I remember when I was losing
my dad from Alzheimer's disease I was at the same time at a
Graduate Studies at Queens University in Aro and we were talking about King leer
and King leer was actually having his aged temper tantrums and uh they were all talking
about you know about aged tyranny that uh that people like King Le
were going through and then the professor looked at me and said well we haven't heard from you David and I said
no I just been thinking of my dad who is dying like King Le from Alzheimer's
disease in which every day is having like a funeral for a
person who still lives the group just was
silent and the professor finally said to hell with King leir we're going to talk
about your dad for a while and for the next 15 minutes or so I was just able to
unload in that group I've never forgotten it and uh now I am still doing what I do
doing what I love to do which is loving to go outside looking at the night sky
looking at the larid meteor shower as I did just last night and also to write for other people
the book that I've just completed is actually for Libby's generation and it is a book for
children and the reason I'm writing it is that of all the books I've done my
wife's favorite is a book that I wrote when I was 10 years old it was called
Clipper and was about our dog about our little beagle that we had at the time
and I I wrote about this dog and it was pre- astronomic days so I haven't found
a word about astronomy there although I think I'm still looking for it I may find one
eventually but anyway I'm looking at that book and trying to think of it and
I asked Wendy one day a number of years ago what it was about that that um she
liked and Wendy said that well here's this 10-year-old no nothing kid who sits
at an old Smith Corona typ writer and types out a book about his dog at age
10 and I've never forgotten that and the phonetic spelling that I
used anyway I decided to write a second version of that about a magic beagle
also called Clipper who would take people out to the night sky using a magic telescope called Eureka which is
the telescope that Scotty sent to me a couple of years ago and I've just completed it I'm
looking for a publisher nobody wants to publish it because either they don't publish children's books or they don't
like this children's book but anyway I think think it's the first book for children that's ever been written that
has a whole chapter about the voids in the night sky I'm trying to explain to Children what a void is and how one can
get excited about absolutely nothing even that especially when that absolutely nothing is
huge anyway I've finished that book with a quotation and of all the quotes that
I've uh read to you over the years and over the months that we've had the Global star party this is the one that I
used to end the um this is the one that I've used to end my book about the magic
beagle Clipper it's by William Blake from his augues of Innocence published
way back in 1803 to see the world in a grain of sand
and a heaven in a wild flower hold Infinity in the palm of your
hand and Eternity in an hour thank you and
back to you Scotty thank you very much David that's awesome well it's uh you know some very
special comments from the audience thank you very much um we uh you know I think
that uh as we learn about um uh the you
know cycle of life and the cycle of things uh through astronomy sometimes it really strikes home when uh you know
these things are personal and um so it's uh um you know I think of uh you know I
think of our uh you know they say that we're made a star stuff and uh stard
dust and um you know so we will we we continue to go on and uh it's so some of
the stories are are humorous you know where uh Norm is talking about hearing
his own father's voice coming out of his mouth so it's uh you know those are all
wonderful things and um so the people that love for us love us and care for us
and all the rest of it it's very special and um you know something not to take lightly and uh so uh you know um uh you
know and David David ier has spoken of his father and and David Levy spoken
spoken of David's father a few times I wish I could have met him uh uh he is uh
I love the way that David AER honors his dad um in uh in some of the
presentations and writings and postings that he does that kind of thing is
really cool so David thank you for coming on to the show again today and um
what what's going to be the topic this time well thank you Scott for having me I'm Ed to be here again and last week I
spoke about a little bit about dark matter and tonight I'm going to talk about a another thing that we really
don't know much at all about but it's very very important in the scheme of things Dark
Energy um and just to to to pitch in a little on that thought it it's you know
you've really created our our ancestors you know they really live on through us
and we are of course made of literally made of star stuff as our old friend
Carl used to talk about and uh you know the atoms in our bodies uh were created
in Big Bang nucleosynthesis or most of them heavier than hydrogen helium and detarium and lithium in massive stars
that exploded so that Heritage that of honoring um our parents our ancestors
lives on through us and Scott you've really created quite a family of people
who are intellectually interested and aware and excited about all these things
and are a group and a very respectful unit of friends and family together with
what you've done so that is quite a legacy from for our from our from you uh
honoring forbears as
well um so tonight David did you want to add something okay okay um so tonight
I'd like to talk about uh if we thought we had a problem in that we don't know what dark
matter is after uh 75 years since Fritz wikii came up with the notion and and
after 50 years after Vera Rubin uh collected the observational evidence for
it we've really got a problem that that began in 1998 um with a discovery that that
created a much larger um yet that really really upset the apple cart of the understanding of the
the standard model of how we know the universe exists and and what's in it
from Einstein of course as we talked about last week we know that the Universe uh is composed of mass and
energy and E equals mc² of course tells us c^ s the speed of light is a constant
energy and mass are the same thing in different interon convertible forms and
we can of course uh test that in many many ways the simplest of which may be
eating a cracker and running across the room and converting that mass into
energy from the plunk satellite a series of satellites cosmological satellites uh
since the confirmation of the Big Bang in 1964 by our Pal's Arno penus and Bob
Wilson Bob Wilson is still around and involved with the staris f Festival um
we know that uh beginning in 1992 with the Kobe satellite and then most
recently with the European plon satellite the composition of the universe pretty well we know it's 13.8
billion years old now and we know that it contains about 69% Dark Energy uh about 26% dark matter
and about 5% bionic matter normal bright matter that is normal Barons normal
atoms uh made up of some subatomic particles so that includes you
know stars and galaxies and trees and cats and dogs and
humans in 1998 however uh a discovery really threw an enormous wrench uh into
this understanding of things um with two groups who were discovering and and
examining a huge uh range of super no of exploding Stars some of those very
things that created all the heavy elements uh heavy as astronomers call
them um and those are massive exploding stars of course at the ends of their
lives one was the Supernova cosmology product that was headed by Saul
pearlmutter at uh Lawrence Berkeley labs in California and it included 32 teams
of researchers the other one was called the high Z that is high red shift or
very distant Supernova search team that was headed by Brian Schmidt um in
Australia and it contained 20 teams of researchers so working partly together
um and partly separately these these groups of teams dis made this breakthrough Discovery uh there was one
person who was a member of both of these teams Alex filipenko who's also a friend
and a contributor to the magazine the focus of both these teams was really looking at type 1A Supernova now these
are exploding stars in a binary system um in which one member is a white dwarf
and it's drawing Material off of the more massive star and it reaches a very
precise point in which an explosion uh that's of cataclysmic nature takes
place this type of explosion it takes place at a very precise and significant
stage of the star's Evolution meaning the absolute brightness of the event is
known very precisely this is the same object that goes back to uh Edwin
Hubble's uh discovery of the nature of galaxies in 1923 as we've talked about before so it
can be used of course as astronomers found as a gauge of distance in a very
critical way a very important so-called standard candle to measure distances and
both teams were looking cosmologically at these exploding stars and also their
distances uh in the late 1990s and found that the some extremely distant
Supernova were moving uh more quickly than they would have been expected from
the normal so-called Hubble expansion of the universe that is that the expansion
of the universe derived from these very distant uh Supernova is accelerating
over time it was always assumed to be a a constant the expansion rate of the
universe the results from all of these groups then agreed so this really threw
an enormous monkey wrench into cosmology and astrophysics the name given to the force
it's it's believed to be a force that is pushing the expansion of the universe apart this Universal acceleration if you
will uh was called dark energy no one yet knows what dark energy is
although many cosmologists are working on analyzing the problem if you want to guarantee yourself a Nobel Prize if you
uh figure out what dark energy is I will absolutely guarantee you'll get one it's the primary focus of major astronomical
research groups now over the last generation it represents more than 2third now of the mass energy of the
universe that we fundamentally do not understand and just to back track to last week we know that dark matter
exists and we really don't know yet what it consists of either so big big puzzles
um that we have uh about the nature of the energy and the mass of the universe
for now we need to be satisfied that we understand here's to put to put it
positively uh about 5% of the composition of the universe reasonably
well uh we do not comprehend about 90 5% of the universe so my conclusion is that
astronomers as long as the funding is still there are not going to run out of work uh anytime soon and that we have a
great great deal to understand about the nature of the cosmos in future years
that will no doubt be very exciting for us to
follow wonderful yes so that's
that's that's all I have and I promise next week we'll get back to some more results instead of just some head
scratching about these two great Mysteries I like the pregnant pause right at the very end it's just like
okay that's awesome it's awesome remember that what I there was a very good movie you know in which uh oh it
was a serious man the movie in which uh the professor who's befuddled with all
kinds of life challenges is writing out you know uh the the uh shringer cat and
other physics equations steps back from an enormous Blackboard you know that's filled with Calculus and other equations
and says so if you didn't grasp you know after this lecture the meaning of it all
uh let me summarize by saying at some great grand level we really don't
understand what's going on at all and and that from the Cohen Brothers when it comes to these two things things is no
exaggeration well that's the adventure you know that we're still trying to figure it out with luckily some of the
greatest Minds in the world so it's awesome okay um David thank you so much
thank you up next is uh someone that goes by the handle of the vast reaches
uh Mr Jason gonzale Jason has been on our shows several times uh and uh he has
uh he always blows our minds with Incredible imagery and uh not it's not
only the images that that he's uh uh you know
really uh how would I say it I mean just it goes beyond expertise it goes beyond you
know when you have someone that can present an image like that that can make you pause and gaze into
what you know what part of the universe this is and then you know I mean it's
awesome to have the the the you know to have Jason there too because he's explaining you know he's explaining what
it is and and um uh he interprets it very well and so Jason thank you very
much for coming on uh I know that you've had a very very busy schedule and so I'm
glad that you're able to make it tonight well thank you thank you Scott thanks for having me
um I had some plans on what I was going to show today but I think I'm going to call call an audible and go off script
here okay based on what David said I I I have a recent image here which is
um a shot of a a Galaxy cluster and and uh listening to his talk just got me
thinking a bit about this one of my favorite things about this Hobby and
this discipline of of astrophotography is is taking these uh shot lots of
distant objects and just kind of digging in and exploring a little bit around uh
what I've actually captured because on the surface you don't really see all these little minute details that end up
in pretty much everybody's Astro photos but um ways to look up and and and
understand a little bit more deeply of what what you're looking at and I think that's what I'm going to show here so I'm going to try to share this screen on
a second computer
please let me know if this comes through yes you able to see that I see
your Zoom dialogue box that's okay that's the wrong screen let me share the
other screen we'll get there okay are you able
to see that I see yes we do see that so I'm going to go full screen with this
image that's the Box yeah I was looking at the other night this is the Box
galaxies singular box multiple galaxies W I've never observed those before yeah
so this is a grouping of galaxies and coma Beres and um it's an interesting
cluster um rather small um to to see
this Frame here just to give you an idea frame top to bottom is about 30 arc minutes so it spans about the diameter
of the apparent diameter of the moon in the sky and so this this cluster here um you
know is about the size of maybe one of the Maria on the moon um which you can see visually but obviously it's way too
faint to see with your eyeballs the interesting thing about this galaxy cluster is um is not only this main
cluster but if you look down here towards the lower part of the image there's also a distant Galaxy cluster
here and a lot of interesting little galaxies peppered around there um some
Edge on spiral galaxies you can see over in over in here up towards the top I can
make it go up there yeah there's some nice face on
spirals out there but one of the things I like to do
with shots like this is is explore what these objects actually are so what I
thought I'd do for this is kind of take you through my process of how I identify
these objects and find them so G to split screen here or actually before I
do this I'm G to rotate this image so that North is
up and that will help us Jason which which equipment did you use for this this is with the EDG HD the 8 inch EDG
HD on a with the ASI 1600 camera and it's on an atlas Pro telescope
Mount I mean that's awesome go so deep U this um process I usually start off
with looking at the simbad database CDs I don't know what those acronyms stand
for but this is a um a database collected I think it's based out of France and you to search objects so I
know in this box galaxies one of the main galaxies here I think it's this um
large venticular Galaxy here is NGC 4169 so we'll start with
that and you can find that data just from uh you know a planetarium software
or something like that that's that's how I found it you can see what this gives you here then is a breakdown of the
Galaxy and all these photometric properties and all that uh All That Jazz that goes with it but kind of what I
like to do to understand it a little bit more is to find the distances to these
galaxies because I think that's one of the things that's interesting is the extreme Galactic distances we're looking
across and where I like to do that is if you look down at the bottom of the page there's this Ned extragalactic database
which is a NASA managed page and it just brings you to another page full of full of information but to
find the distances information you can look here at Red shifts and that'll show you based on the
cosm some assumed cosmological properties distances to the galaxies in
mega parex and for closer galaxies it agrees very well with the uh this
singular property here which is light travel time and that's 10
94 or 0.94 gigal light years which is 194 million light years so this galaxy
right here is roughly 200 million Lighty years away from
us where things get really interesting is when you compare um say
for example these these other galaxies in the
cluster you can query the simbad database to a radius and you can't see it there 20 I'm saying
20 Ark minutes around this galaxy show me all the objects it's amazing that
that an amateur telescope can reach that I agree so the um now if you look at
this it's opened up a viewer called Aladdin which shows this field of view
you can see it matches mine roughly this is from the uh DSS Sky survey you can
click through different Sky surveys and see different views this is the sdss
survey alone digital Sky survey but you can then look at these galaxies and you can hover over them and you can see it
highlights over here which one you're looking at or vice versa so as you scroll down here it highlights these
different objects what it also has listed is the object type in this column and you can see um
this is say for example and you can click on here and get a a key but this is a safer type two Galaxy g just stands
for galaxy C is cluster of galaxies this is Hixon 61 so this
defines the box and then qso is a quasi Stellar object so that is a quazar and you can
see hovered over here the green box shows where that quazar is it's in the
The Faint arm of that Jas we've lost your
audio lost my audio I still hear Jason Scott can you hear
me hey Scott are you there can you hear me check I can hear you Jason y okay I'm
good can everybody hear me sorry guys yeah okay so anyway um I don't know
where where I dropped off but um I'm hovering over this this quazar
here which is in the arm of the Galaxy if we zoom in real close to my image
zoom into this image you can see that the same Dot of light is illuminated right so let's have a look at this
quazar in the Galaxy click on here and then into the
med database and into the red shifts category to look at distance your
picture on the right there that's my picture on the right yes oh my gosh awesome looking down into light
travel time to this quazar you can see there 9.
two billion light years away what
wow and so interesting thing with with quazars is is they're tremendously
distant objects moving away from us at tremendous speeds and because this light originated
so long ago the expansion of the Universe plays a significant role in how
distant these objects actually are from us right now just because this light
left that Galaxy 9.2 billion years ago does not mean that it's 9.2 billion
light years away it's actually since that light left that Galaxy it's been receding from us the entire time right
if you look at these velocities up here which Define how far this G Galaxy or
this quazar is receding from us these actually exceed the speed of light which
is about 300 kmers per second second so that that Galaxy due to the expansion of
the universe is actually actually receding from us at higher than light speed well it's
not receding at higher light speed but the universe is expanding right the space itself is interstitially expanding
it's it's like it's impossible to wrap your head around when you start thinking about but that's
incredible and and you have even 41 69 Jason is is a sefr so that that has a
very active black hole is is an AG then you've got a vastly more distant quazar
in the same field there the the center the very active uh black hole driven
center of a very young Galaxy so that that's an incredible field of galaxies
here yeah it's incredible it's great yeah so the you know it's I won't spend too much longer on this because I think
think I've taken a lot of time but I I find this really interesting just to kind of step back and explore these
fields after I've captured them and um you know we can just pick a a Galaxy out
or or let's um let's say you know come through this list and look at there's other quazars out here we'll see if
uh clicked on some of these obviously let's yeah Jason I mean what
you're doing here is fantastic with the the tools and laying it out because is exactly you know how and and what's nice
is with this type of object it it gives you a lot of uh it's like a test object
because there's so many depths of field and for aperture for Imaging that the
facts of all all the different types of objects this is really cool and and also I really like on the left how you're
showing the simbad and the you know how to how to identifying and do your own PL slot
solving visual PL slot solving this is great this is kind of a hybrid between actually plate solving your images and
identifying objects and kind of star hopping using a star map right that's kind of but that's kind of what I like
about it and Jason sorry for interrupting but you're in just to to to add some more you're you're in exactly
the right place these are the two definitive databases for deep Sky observers Ned at at JPL Caltech and
simbad at storg TH those are the two most definitive data sources on the web
for deep Sky objects of all types so those are exactly what deep Advanced
deep Sky observers should be using yes that's
great that's cool thanks David these are great tools you know here's another
example so I looked up this galaxy here and I know I wasn't tracing my path but I I want to know how far away
this galaxy cluster is or at least some components of it right so um I had
looked up this object here which I have my mouse over right now and that's showing a distance
of one 1.8 billion light years that's pretty pretty significant
distance just to that cluster there that's amazing yeah
yeah who would have thought Scott and D 35 years ago that we would be sitting
here with amateur instruments Imaging quazars that are one to two to n billion
light years away yeah that was that was in the realm of the big telescopes for
sure this is Jason's personal Deep Field um image yeah well I take a lot of these
I really enjoy poking around you know and it's this this forum and thanks
Scott for for having it because you know this is a great place to to present present this because you can kind of
walk through it and show people so that's great I hope you enjoy the the little yeah we do do walk through the
field but yeah I mean if there's anything else you want to look up here or anything well my comment is that um one
thing we've learned over the years is that the longer the exposure and the more data you have you can in some cases
overcome aperture but it's a combination of both that just really gets you all of
this dat that you collect and then if you're expert at processing it you end up you
know you end up with this sort of image and I think it's some of that knowledge falling into the hands of uh us amateurs
that you know it really started and the availability of equipment that tracks
well enough really made it so that amateurs could we could provide shots
like this now I my Deep Field would be a picture of stars but it all depends on
you know how much time and expertise you spend time and experience you have doing
this um obviously we can we can produce really good images and I know Jason
Jason's one of the ones in our astronomy group uh we've got a few that produce
some really nice images um building building observa building home observatories and every
clear night hitting the button and Gathering some photons so it's uh it's
definitely a passion yeah yeah actually Adrian we were talking about that couple of star
parties ago about kind of cloud clouds uh cloud-based uh Imaging where where
you you you know you just collect images uh and and do your own plates and then you can combine them you know in the
future that's that's where things will be going right we're all kind of getting bits and pieces of of that puzzle right
now and then you can imagine doing SI you'll be able to discover um you'll be able to discover Nova all sorts of
things I mean obviously there's a lot of lot of other professional telescopes that are out there but yeah but I think
that when when we have an army of amateur astronomers out there with this type of Technology it's G to be un
Unstoppable oh will'll Have Eyes in the sky and a lot of times some of these things can be it can be a little bit of
blind luck too we may have pan stars and um the other major Sky surveys but you
know an amateur could still be the first one to look at a particular part of the sky plate solve it and say hey that's
new what's that and end up still making the type of discoveries um you know that
you know 35 you're talking 35 years ago um you looked at it through a telescope
night after night um you know we're we're becoming more capable of having
kind of Our Own rig to do that and to be able to you know be able to do those sort of things so just having the time
is almost all that would matter at this point because it's U it can be very timec consuming to learn a lot of this I
know you know most like Jason have been at it for so many different so many years um so it's but after spending that
time you know then you then you get to the point where you're contributing real science and that's
that's when it gets exciting when you when you're contributing to ongoing
study of uh of our universe and that's I think that's the appeal of astrophotography in general is being
able to take part in it and there's still room for visual astronomy as well this
all you you like that's where you need all the big apperture into Dark Skies but if you can
do that you um you know you start picking things out with your own eyes and it becomes it becomes exciting so
there's room for both the human brain is still the best computer and uh you know we collect a
lot of data and we still have to comb through it right and and interpret it so yeah so we we all we all look at it and
we we can create a lot of great insights yeah for sure you know there's
alternative ways to do this what I just did um and a lot of the software processing software now has automated
ways to to go in um into cataloges and and um you know plate solve the image and
and um and annotate it so that it's got these these pieces of information but I
still kind of like going in there and poking around see what I can find as we were talking I found this quazar here
that I circled on my image which is um 10.8 billion light years away so
just this field
gosh but if you look in if you look in some of those Galaxy clusters and try to find
properties on some of those things it's just not there you know a lot of these these faint distant ones there's just
not a lot of information on even in these these databases which are some of the most extensive we have it's pretty
interesting still right and and what you were saying Adrian is absolutely true you know I I like to observe mostly for
the fun of it I don't feel like I want to be out there doing science and for many years professional astronomers sort
of gave a wink you know and said well if you'd if you'd like to contribute you know your data that's great and not a
whole lot happened there now this capability you know with the chips that are in cameras now and with the
positional the astrometric Precision that amateurs have we're seeing evidences of it tonight and even
symbolically in this image you really can produce data that is literally of
tremendous value to professional research if you'd like to which really is is a is to be totally honest is
really kind of an evolution of the last decade or 15 years you know so it's very
exciting to have that incredible power in in the hands of of imagers like you
guys yeah yeah and you gota you got to realize too that um this you know this
equipment is accessible it's not you know like um
it's not in the realm of professional you know astronomers anymore you've got you know just a backyard setup here
shooting under moderate light pollution um you know my bordal class is
five perhaps six in the winter when the snow's on the ground but yeah you know
not tremendously good Skies not tremendously good equipment but yet you know would have been impossible a long
way yeah well you we gota we got to be careful with that capability I think um
you know our fight against light pollution if we come up and say well you know we can still get this data um I
often wonder if it's we you know if it's countered to some of our fight to preserve the night sky so that we can
see it visually I me it would turn into a thing where you have to you have to be
an a an astrophotographer in order to really see what's there we hope it never gets to
that point you know we we hope that we we find ways to preserve a dark sky you
know and basically every country that's watching this um and Beyond you know we
we hope that you know future Generations get to see what a dark sky looks like
we'd like to see that improve but in the inter room we do have a way to cut through it you know it takes a lot of
time it t it takes expertise the equipment is there but the expertise of
a Jason gunzel takes time to understand how the stuff works and then to know
what you're looking at um you know you get a bunch of dots or if you if you
plates off you know that okay there's a little Galaxy right there you could look it up and get information there's
another little Galaxy there's you know there these dots and uh blurry dashes
actually represent something in space that's you know so many millions of light years away and um you one more
quick thing we talk about time machines we're looking at a time machine
probably the one real time machine that we do have is Astro equipment where we
can look back into we can look back into time into um when this light basically
where this light comes from um so there's there's a lot of
fascinating um discussions you can have just on the is one image that's that's
true that's true thank you very much Jason that's great welcome yeah our next uh our next
speaker is um is John Briggs and John uh is uh you know I liken him to
kind of like the Ken Burns of the amateur astronomy world uh he uh puts
together so many wonderful programs uh we were talking earlier uh you know
about uh you know the fact that he said well Scott I could I could just kind of uh uh I'm not going to say wing it but
he can talk about all different angles all kinds of subjects of of astronomy
but the thing is so cool about what John does is he reaches back into the history
of astronomy and shows how it's relevant uh to us today and um so uh I'm I'm
interested in his new presentation he just sent it over um so I get to play it for you um John do you want to say a few
words before we get before I start sharing my screen well thank you so much Scott it's great to be here as always
and so um there happens to be this obscure Observatory on an island off the
coast of Connecticut that I started hearing about as a a young person
interested in astronomy growing up in New England and eventually I had a chance to visit this place a couple
times and it's a very special Observatory and so uh I hope uh people
enjoy uh the short presentation that will um uh show it off to you all so you
can uh let a rip Scott and hopefully the connection will be better for you than it is for me here in uh New
Mexico okay let's see let's uh let me bring this up and um start sharing my
screen in fact and sound and sound let's
see so let's bring this
into there we are this is John bricks in New Mexico going to tell you about the E
Wilbur rice Observatory one of my favorite private observatories I have
ever visited because I think it is one of the most
beautiful not go up that loud okay there we
go I found out about it slowly over the years as a young amateur astronomer one
of the clues was this advertisement that appeared on the back cover of the
telescope magazine in the early 1930s what does the caption say 10 and 1/2 in
refracting telescope for the private Observatory of ew Rice Jr fiser Island
New York but built by the Warner and suy Company um none other than Warner and
suy uh what a company what a
telescope to understand what Warner and suy was all about you have to look back
at some of the great observatories of the early 20th century like yores shown
here built by University of Chicago yeres still exists and it is a
wonderful place to visit in southeastern
Wisconsin even before you walk in the front door of course you've begun to realize it's a very special place but
that's reinforced further as soon as you enter the
building look at the scale of the 40in refractor
at yur's Observatory see the visitors down below entering there in the main
doorway the 40in refractor dedicated in 18 uh
1897 was built by Warner and suy and to this day it Remains the largest
refracting or lens type telescope in the
world Warner and suy built great telescopes but who was e Wilbur Rice Jr
Well turns out he was one of the founding partners of the General Electric
Company here he is as a young man with the goatee a little left of center there
um hanging out with other pioneers of electrical engineering like uh Lord
Kelvin on the right and ELO Thompson the other figure so connected with General
Electric and many others and if that picture with rice
with Lord Kelvin wasn't enough here's rice closer to retirement he's the
fellow on the left and the fellow on the right is none other than Thomas
Edison growing up as an amiter in New England I heard clues about this Observatory
even from Walter Scott Houston the famous author of deep Sky wonders column
and sky and Telescope magazine Houston had been out to this Observatory Fisher
Island is off the coast of Connecticut and it's part of uh New York State and
it was there that Rice built a beautiful summer home and here it is and to make a
long story short with the passage of time as I grew up I was able to get
acquainted with the people who own the observatory and eventually go out and visit a few
times behind the beautiful house there's a lovely little New England
garden and above the garden there it is
the rice Observatory wow to get inside you pass through a
warm room let's check it out immediately on your left there's
wall clock built by the Howard company and it keeps siderial time inside the
cases are beautiful accessories very different from what we typically use
nowadays in another corner there's a workstation and of course it's a nice
table for spreading out a big star Atlas this place was built before goto
telescopes and on the wall a nice little Library sky and Telescope magazines no
no this place was too early for that these are popular astronomy published by
goodso Observatory of Carlton college that was the the main magazine of ason
omy before sky and Telescope but curiously there's there's a a basin why
the Basin well that was because in the opposite corner of the room in a closet there was a small dark room so of course
it was appropriate to have a sink just to wash your hands after developing glass plates and the like in the small
Observatory dark room but finally a after ascending a
small small set of stairs and going through a little spring-loaded gate the
main attraction the 10 and 1/2 in refractor built by Warner and suy with
Optics by CA Robert
lundine and it is simply a very beautiful Observatory beautiful
instrument of a great facility
the controls of the telescope what a magnificent focuser it's a 5in
finder the big knobs on the right are locks and slow motions for our angle and
declination the small textured knob is the hour angle lock to engage the clock
Drive um the smoother knob below it is
the blck for declination that allows the Observer to tell the difference easily in the dark
notice that all the handles are wood because wood doesn't conduct heat so
ofly as metal so when you using this telescope in the cold winter time it's
not so hard in your hands it just makes
sense Warner and swayy built telescopes and mountings that were simply
rollsroyce quality their main business was building a heavy machine tools like
like turret lathes and Milling machines things of that nature but Mr Warner and
Mr suy were amateur astronomers in their own right they loved telescopes and they
built magnificent private ones like this and among the world world's largest in
the early 20th century for the most serious
research there it is the Warner and suy Company Cleveland Ohio
USA the German equatorial mounting came with standard setting circles beautiful
big setting circles nicely illuminated but uh up near the North End
of the Polar axis there an additional polar setting Circle that's a slip ring
circle like what's built into a typical Schmid Crain telescope that allows you
to set the right Ascension of any object you're looking at in the beginning of the night and then that circle is
carried on as long as you have the clock drive on synchronized with the sky and
allows you to point the telescope reading right Ascension directly right off that Circle a very nice
feature there are details of the ey end however that um uh deserve special
attention let me show you the beautiful focuser components
detach by means of beautifully machined bayonet
mountings with the heavy focuser removed the telescope could carry large
accessories like this plate camera made by the William gerner company in Chicago
this camera allowed the use of glass photographic plates not quite 4x5 in
format I can't remember the exact format now uh there's an off-axis guider built
into this the the uh rim of the eyepiece is black and it's pointed down to the
lower right there are X and Y slow motions so that to use this camera you
would do the guiding by moving just the plate holder not the entire telescope of
course the camera would be mounted to the back of the telescope at the correct position angle but what a beautiful
accessory what a wonderful thing here's the camera attached to the
telescope notice how it's mounted on a big ring that is connected by four brass
bars that crank out down away from the main tube of the telescope allowing The
Observer to focus the camera there's a spot on the side of the telescope
allowing The Observer to insert a big Crank that when you turn it this whole
apparatus for mounting the camera or other accessories Moves In and Out in a
fine motion up behind the back of the telescope now that's the way to build a
big refracting telescope if the play camera weren't an
interesting enough accessory there was also a combination spectroscope and
spectrograph this instrument was made by the fcker company um and it had for the
dispersing element in the instrument an interchangeable prism for low dispersion
spectroscopy or a fraction grading that was ruled at the Johns Hopkins
University for higher dispersion work um what a very cool
thing here's the front end of the telescope looking rather curious because
I've removed the 10 and 1/2 in objective to clean
it here's the 10 and 1 12 in objective in its uh brass cell which happens to be
painted black and it was made by CA Robert
lundine now lundine like his father
worked for the Elvin clarkinson company in Cambridge
Massachusetts but by the time this telescope was made lundine had set out
on his own in Watertown and by not so long after this
scope was built lundine was actually working himself for the Warner and suy
Company here the lens cell has been lifted away from the two glass elements
interestingly lundine used a flint forward Optical design the Flint type
glass is actually closest to the sky in this particular Optical design the
thinner Crown element at on the top of the stack here was actually towards the
eye end here's Robert lundine in a publicity
shot recorded at the Warner and suy Company testing Optics in a large
laboratory but this rare photograph shows the same man Robert lundine here
on the left hand side as hardly more than a team teenager and this image was
exposed in the Elven Clark and Sons Factory in MA Cambridge
Massachusetts when the the the staff there were working on none other than
the mighty lens and cell for the 40in refractor at yur's Observatory that is
the objective cell shown there suspended on the chain hoist but to go back to the picture
showing the front front of the tube with a lens off notice the tube was really quite a bit bigger than the lens this
telescope could have carried a bigger lens in fact the rice telescope mounting
is mechanically twin to this one this is the bural memorial Observatory at
Baldwin Wallace University and in this case the Warner and suy mounting is
carrying a 13 and 38 e inch aperture refractor but these mountings were so
strong larger tube assemblies were just no problem at
all my youthful interest in the history of rice Observatory was really rewarded
and that's because I learned why Mr rice had such a strong Warner and suy
mounting he had not been satisfied with the first tele scope he had in his
Observatory the the pictures you've been seeing are not actually showing what his
first telescope was I learned that it had been another telescope an 8 and 3/4 in refractor and
his 10 and 1/2 in had been a total upgrade I learned that the 8 and 3/4 in
have been donated to a school but never used and never housed it was lying
around in a pile of parts I built this Observatory to house
it and I did everything myself the windows the doors putting the glass in
modifying a farm silo into that Dome I was very proud of it let me show you how
it turned out this here was the original telescope in rice
Observatory an 8 and 3/4 inch refractor with Optics also by robertt lundine and
the mechanical Parts contracted through Robert lundine but it
was a little too rickety for Rice demanding
taste but it was sure good enough for me when I found the parts in storage at the
birkar school in Western Massachusetts and they gave it to me I lovingly
restored it I painted it red um I lacquered the steel setting circles and
everything else and I had a wonderful time with it for many years at this
Observatory I built back in in my boyhood home it wasn't as fancy as the Warner
and suy on fiser island but man it sure was fancy enough for
me uh we could go on at length admiring telescopes but thank you for your
attention uh as I've shared images of the 10 and 1/2 in out on fiser island uh
truly one of the most wonderful private observatories that I have ever uh
visited or come to know wow that was great
um is there anything that you'd like to add to that uh presentation John
I I should have mentioned that the observatory was built the rice Observatory was built in the early
1930s um and the uh what what what came to be the red telescope when it was new
cost a little over $5,000 of course that was a lot of money in the 1930s sure I I don't know how
much the Warner and suy upgrade cost but I bet it was pretty expensive but Mr
rice was obvious viously uh quite a wealthy man and um anyway these
telescopes uh they're objects of art as well as objects of Science and uh if I
were interested in cars they'd call me a a gear head because I love the hardware
maybe I I I could have grown up uh tuning carburetors but instead it was um
learning how to callate lenses and stuff like that so anyway thank you for your
attention and uh I'll keep sharing these kinds of things in the future I hope
great great thanks John thanks and uh you said you might have a presentation
later on tonight so um I I'll I'll see I'll see what I can
improvise a little bit of technical difficulty with the other one but we'll see what we can do but thanks a lot
Scott all right thanks John okay so uh coming up next is uh Libby and the Stars
Libby has has um has uh really grown
with us as uh you know as she's gone along she has been at I think almost
every one of our Global star parties except maybe for one uh when uh she was
um uh uh back back East but uh she can correct me on that if that's not the
case um she uh as I've watched her give her
presentations she's gotten better and better all the time and uh uh I think by
the time that she keeps this up uh by the time she's a young teenager she'll
be quite expert at uh giving presentations and uh disseminating
information about the cosmos and so Libby what are we going to talk about
tonight so tonight I will be talking about satellite images and I'm willing to share some
images from my um for my absorbing I got to do last night I've been with all of
my telescopes too so satellite images um the satellite images of Earth and um I
was thinking about this because a long time ago when I was at space camp all the way a long long time ago I remember
doing a presentation on what would happen if um nasaa there is a
volcano like from Earth on all of their satell lights um or any natural disaster really
um if it's big enough to see it from space NASA can see it from up there and get help to authorities around the area
that might not know there is a natural disaster going around and um in an image
over here out here a little capsule you can see a hurricane so you can also see
hurricanes from space too and you can see the eye of the storm which also helps know
like how storms are coming through and this also helps with Radars too if you
look at um The Weather Channel that that stuff if you're going to check the radar
the radar um is um you can get some of the radar
from um if it's a big storm from space and most of The Radars come from space
and that's to helps with that stuff and um I always thought that was cool because I'm very into weather too as
long along with space and um it was really cool to know that um and NASA can
see all the clouds from space too so they can also see if a bad storm was a
bad hurricane or storm was forming over one area theyd be able to let people run
the area know and then um another thing is satellites from other planet so I
took um I made a little chart and I took um some information from Jupiter so all
of Jupiter satellites that ored around and watch it um all satellites I orbit around and
watch Jupiter and some of some um some are not satellites that go around
Jupiter some just go around Jupiter before they make the missions kind of like the moon you think that there would
be satellites around the Moon well there's not I mean there's one right now from China but mostly people would go up
into space and then they go around the planet and then they would land on the planet so there's not really a lot of
satellites around our moon but I took um I made a little bit of um a
chart um of all the satellites that have been around Jupiter and Jupiter is a
very Stormy Planet so um NASA would be able to
watch Jupiter's storms go around the planet and that gives us a lot more
information and another thing is signal satellites so signal satellites give us
Wi-Fi and stuff so some people a lot of people around here have signal dishes
outside and um your signal dish connects all the way to um the satellite out in
space and then back and then back to give you satellite to watch TV and stuff
so my grandma and grandpa have that because they live very far out in the country and um whenever it gets rainy
there satellite gets messed up so they can't watch TV so um I thought that was really cool
because I have experience with satellites and um a long time ago when I
was about eight I got to see um Falcon 9 launch with a satellite giving um
ringing satellite to remote places in Africa so I got to see a rocket launch
with a satellite in it and that's probably like the best space experience I've ever had in my
life and um I wanted to show some pictures from my recent observing so
um this photo here I have all my um those are my newtonians and then this is
my Galileo and um I have my tent set up outside and I just took a picture of my
um like my uh neonian not my neonian my do tonian in the um tent with the moon
which you can't really see any details on the moon and then um this telescope here is a telescope we found in my dad's
my dad's childhood home addict that my grandpa owned and I never knew he owned it and so um I took it and I got a new
lens for it that Scott gave me and I tried it out and this is the picture that I got from it and
um it it was really nice to be able to um see that and um very nice I put my 6.4 lens
in my do sonian and um I did have a very hard time trying to take a photo with a
cell phone but I most likely more enjoyed it when um when I wasn't taking
a picture with the 6 for lensing because I just mostly got to experience it and
um I say my um my Tasco telescope probably did the best out of the full
night and I um my best part of it the full thing is um I taught my mom how to
use a galileoscope which um I recently got a galileoscope because I um have been
filming a video for one and um my goal with that telescope was to share it with
my family because um my dad had like is good with
binoculars cuz um he likes to um do fishing and stuff and so I thought it
would be a good idea to let them use my um galileoscope because it's kind of like binoculars and so I taught my mom
how to use it and she got the um she got the moon in her lens for a while and
she's really excited about that which I was proud for her achievements and um I took home my um
newtonians photos together in my Gallos scope that's my first
telescope my um second the newest telescope my newest one and then my and
then my probably second third newest one so I
had all my telescopes out last night because I didn't have school today because that was um remote learning so I
got to spend a lot of time outside during night time taking some photos of
um of after like a week of cloud so I just thought I would share um I thought
it was very inspiring um that the telescope that was found in the Attic
could take an amazing photo of the Moon like this and I wanted to share some of that because I haven't gotten to do a
lot of astronomy in a while so well that was very good that was
excellent I I really enjoyed also to the fact that um uh your images through the
eyepiece are getting better and better all the time so um you know you're doing
a great job Libby so you know thank you thank you for having me on um by the way
I think I joined um about the seventh or eighth Global star
party oh I see I see I I've been trying to um keep track of that so I know and I
don't foret so you're almost up to 40 star parties that's that's pretty good
that's pretty good awesome well wonderful um liby uh
thank you again uh up next we go down to Argentina uh to Cesar brolo uh Cesar how
you doing today hi hi SC how are you uh
well actually I I uh shooting uh to the
to the um Southern Cross last week we um
I show uh um only one star of the
[Music] sou um mimosa and and a part of uh Co
sack Co sack is okay in English because it's yeah yes in my mind all times in Spanish
is a s Caron but this Sal uh sack No Coke sack yes sack Co sack sorry my
that's good you got it you know I I have a mix of Italian
genetics I live in Argentina from thir generation I move my hands like an
Italian but Argentina and it's awesome it's good yeah actually
actually I am stacking the pictur um where we cooking the the things well I I
can share this because okay I'm using actually I'm using only let me check if
I can
um I don't know if the process ah okay okay stacking is another
another is like another um you can see the the window of
stacking yes is like another stack okay it's like another window um and do you
have the bars of the processing yes okay okay here no because the
problem with sharing the screen is that I never know who is that I sharing
because we don't have the system that where you choose different Windows to sharing and well actually
sorry but I am only the N uh 19 of 63 I
I took uh um 63 pictures the darks and
vas I don't took the flats because uh it's no easy for a um Regular SS or
photography take a real flat because sometimes in your flat for example here
where when uh I'm take taking pictures from from the
balcony I have different I have different Reflections in the lens from
you know another another window real windows and from another weldings and
lights parasit lights and it's not easy to recreate in a
flat um flat is it's well we know all
that is a flat but the flat is in information for the people that maybe are listening now and say what is a flat
is the information the picture where do you have the information of
scratch uh different type of B in different uh condition of life in in
the in the screen or much better say uh
in the sensor of your camera and um it's
really uh easy to to have an uh great um
flat with the great information from a telescope but sometimes it's not
easy take a great flag with the the right information to to subtract the the
errors uh in a regular uh photographic objective
this case is assume is 130 100 sorry 300 millim uh last week um
um we talk about uh with uh Adrian bradle that he told me the right way
that is the crop sensor when you have a es uh uh let me
think in English a APS apcs
uh sensor size you need apsc yes one yes yes see yes thank you
Adrian I'm for me talking in Spanish when I translate to English it's a
nightmare and uh you're doing fine yeah and the calculate is
1.6 if you don't have a fullframe camera and you have a normally regular reflex
camera most of people use a pssc uh sensor size and um when you use
not when use a vintage zo like this you need to you have a vintage Zoom or
vintage objective uh uh for the 35
mm uh diagonal size of a sensor of the analogic film uh uh um system of the
cameras uh maybe Le say
what because like my my kids uh I sometimes ask me or said you
really took pictures of sky with with film yes was the the most normal in uh
um before the 2000s uh in the 90s or in
the 80s we used uh film uh for for take uh
picture of the skies and you know maybe you left a com two or three 35 exposers
film to to have one do sh well this is too too this is too long
it's only stacking 49 and 63 to I don't know how is this picture
is is something like uh develope I this
sometimes when uh I don't know if you Adrian or another
astrophotographer have the expectation when start to stacking in a program uh is something like a remember
me or remember myself the time when I went to the photographic photo store to
have my develop films and now it's too comparing but for for us this process is
like our develop of a pictures stacking pictures where I used 63 pictures okay I
don't know I I can I can't expect anymore but maybe maybe in the past with
with a if you was lucky if you have maybe not I don't know three or four
days days or sometimes 24 hour in laboratory to have your uh develop uh
film well is I think that this uh this is really to be to be uh near to have 40
this say 44 seconds we can check if it's okay and we
we can uh we can see how the picture of the Southern
Cross is because I'm really too now these
pictures
okay this is the worst part because I'm sorry that that really I I started to to
took pictures more early I I could be
possible for me today but okay Computing finale
picture SC you can see the the the bar of of the process
not just starting yes yeah just starting well
okay six well um this is this is interesting
this this this week I um I was interested in in show
um uh the the especially the the the C sack
because it's interesting that the C sack is a huge a huge
um um formation of dust and it's really
very in a very different distance of uh the Southern Cross I
don't remember the the the the the distance of um for example Mimosa or H
acus or or or uh the another stars of the Southern Cru but I know that the the
this formation of of dust is really more near to us like the the
stars of the Southern Cross the the
the this the formation of D is around
600 like years I I don't remember the the the
distance of for example Mimosa but I know that it's in another in another
uh uh distance completely different maybe two or three times
more uh that the this with the with the co
suck and uh this is something that you can see when you you see the the cold
sack you you can see that the quantity of stars of stars from the M way is
completely different you can see really a few number of stars this is really
because it's it's a in a plane more near to us that of course the the the the
another stars in in the South Souther uh
cross uh constellation Sorry by but sorry by the
the EXP expectation the expectativa is in in Spanish but this really is cooked
now it's like a you you are opening the [Music]
the yeah it's like you're opening up the CP door yeah yes C is this it's a
disaster it's okay it's completely yes hey the computer's working as fast as it
can okay so I'm happy to share that's right there's a lot going on a lot going
on I think it's still valuable because remember it's sometimes it's not about
the uh end result so much as it's the journey it's the process is um this is what it looks like
for that are interested or you know that do this sort of stuff as a hobby um
they're very familiar with the long time that it takes so I think it's very
relevant and and those that are new to it or haven't done it before have no idea okay so it's it's a good it's good
to show it's good to show this in real time I always thought that this was my
favorite part of the whole process watching the final stacked image pop up on the screen yeah it's first time you
actually see the you know yeah
another suspense yes like am I gonna get something good or is there GNA be a real
streak going across my picture and is it gonna be no good or is it gonna be all
whitewashed and your your analogy to to uh photoprocessing in a dark room with
chemicals and film AB you know uh was a much longer process you know and so yeah
this is when I was kid my father b a a copy the copy to project in
the paper we developed the the black and white film and I remember when he bought
the the was like I don't know copy Adora or copy copy machine to to to to to put
the the image in the papers when you you so magic when you put uh the
photographic paper and start to to to show the the image was magic here is
maybe I need to to have something more uh not so um you know you can see only a
bar but okay
well the Moment of Truth this is the city of wo really really I can see only
the the stars of the sou cross only sorry that this is not F inside but
you know you understand me that this is but I love this because it's easy it's a
easy program to understand for the kids especially I don't know if I am Mega
disaster oh no Soo much sorry okay but I
can any any suggestion is
welcome no normally the best normally the best thing is is uh
export without touching with this program this
okay okay and don't make with this if
not okay looks like you got a few more stars to come out yes yes I I can I can
move a little to the to the left this to use
more okay Y and
now better yeah better better yes with more
of course that you're going to be doing yes yes iise make a better work with this
because we have a lot of information here here well okay here we
have maybe I don't know if I can use okay here you can
see uh the red the red one
star uh very near to to Mimosa star here
do you have
yes here if I process more I can maybe I can show you here well okay here in this
dark area maybe you can see the the the co sock the co sack the co sack
yes and really do you have a lot less of stars really a number very few comparing
with this or this area the chicken the I I remember that the chicken the running chicken is in this
area if I make a better Pro process with P inside I can use I can maybe take
information in this area and let me check if I can
normally the best
green um in in every pictures do you have a lot of of green more that than other
colors it's okay it's normal because the sensors have more
green I'm checking if I can see something of
the the running of the running maybe here a little but I can
make something to to to see this area because the problem is that I as I
can I can make a great flat of to to to have the information the uh of this
objective maybe I can't uh develop more areas
interesting especially the the the nebula but well okay is do have here a
lot of stars uh and um I can I don't know now I
don't have more time because we are going to the 10 minute break I think but maybe I prepare this with a better
quality for for our next talk and we are I propose start to talk about different
objects uh you know history uh with more
more ER for example this this the sou CR area
that is different because in people from North Emer don't see in a gray in a gray
altitude the the this constellation a real south Emer con constellation um but
um I prepared something for the next next week about some some something of
the physical properties or you know about the different stars or clusters of
nebulas in this area great great okay all right thank
you very much Cesar okay yeah you can if you want you can come back after the break and show us
again we have some other people lined up but uh let's let's see more that's great
yes absolutely it's is a all times thank you for your attention every every time
is a real honor for me be a part of of this it's an honor for us too Cesar
thank you it's it's you make it uh truly part of the global Star Party experience
so that's awesome that's awesome thank you thank you okay so next up is uh president of
the astronomical League Carol ore who has uh spent much of his uh adult life
working with the astronomical league and uh working with amateur astronomers um
it is um uh it's a it's a privilege for us to uh to have him
on um our programs and uh he've been on several times and uh and we love it so
Carol I'm going to turn this over to you and thank you very much thank you Scotty
uh fascinating talk by our previous speaker that was really fascinating gives me a new appreciation for all the
work that's really involved and all the stacking that takes to produce those beautiful images okay I bring Tidings uh from the
astronomical League uh we are a an organization of
uh uh 18,000 members and we uh are
really uh celebrating some major events lately this year in fact we're going to
celebrate our 75th Anniversary one of the things we do each
time we have one of these parties is giveway door prizes so uh we start with
giving warnings about anything you would get as a door prize that would be an
high piece or something like that or just in your personal observing make sure this is one of our standard
procedures we want to warn everyone not to look through Optics uh toward the Sun
so we have to have the filters on that okay first of all as I said before
in about two months we are going to celebrate our 75th Anniversary as an
organization and in addition uh my colleague John Goss was on a couple of
nights ago in fact last Friday night and we are for the first time in a couple of
years going to have a National Convention we weren't able to do it last year and had to cancel or postpone I
should say our convention at Albuquerque New Mexico however uh we find ourselves
still in a pandemic mode again this year and we are postponing that until 2022
however the good news is that Scott and explor scientifically explor explor scientific
have graciously agreed to do a lot of the heavy lifting technically and so we're
very fortunate that that's available the dates we didn't have last star party but
they will be August 19th which is a Thursday through Saturday night the 21st there
will be blocks of time around the dinner hour uh in the uh Central Time Zone and
so I encourage you to consider that okay first of all we're going to
give the answers from the previous GSP uh
41 the first question was to obtain the clearest sharpest views of surface
detail when is the best time of day to observe the first quarter moon through
binoculars or a Telescope shortly after Sunset around midnight or just Before
Sunrise and the answer is a shortly after sunet it's the highest in the sky at
that time so it makes it much easier to observe the second question
was on April 26th and 27th Mars will lie in
the sky next to M35 Maier object 35 a bright star cluster SE in binoculars how
much farther from Earth is M35 than Mars 100 times farther option A about
100 million times further or option C over 100 million times further and the
answer is about 120 mil times further that's
option
C the number three question when looking
through a telescope an eyepiece with a shorter local focal length gives a lower
magnification than one with a longer focal length is that true false
the answer is B false the shorter the eyepiece is focal length the greater the
magnification so the one on the right would give a greater magnification the 5.5 millimeter as opposed to the
26 and the answers to that star party of April
16th are Andrew Corel Norm Hughes and book Davies all right and the we are
doing this we're doing this just a little bit different now we're using a number generator and award door prizes
on the last GSP of the month and they'll be added to the list of door prize so congratulations to these three and good
luck as you move forward in the process right and the questions for uh our star
Pary send your answers to secretary at astro.org yeah you do not want answer
them in chat you know yeah that slows the process down we want to get those to
you as soon as possible so that's the best way to do it so question number one for tonight's star party what is the
name of the bright red star in the constellation
Scorpius what is the name of the bright red star in the constellation Scorpius
and again send your answers to secretary at Astro league.org everybody got that I
hope we're flooded with answers to these questions number
two what is the name of the latest United States Marge Rover that arrived
on that planet in February of 2021 there's the graphic to the right I think
it has eight uh eight wheels and it's a a super cool
uh vehicle there what is the name of the latest United States Mars rover that arrived on that planet in February of
2021 and the final question tonight what star appears as the end of the
handle in the Little Dipper what star appears at the end of
the handle in the Little Dipper H everybody's got that you're already sending the answers
right and everybody should get that one get a thousand answers for that yeah set
up to secretary at astro.org thank you so much thank you and the next
Astro League live number five will be coming back uh this Friday night April
23d featuring Howard Escalon from uh
Alpo uh he's going to be talking about the Galaxy song cosmology Perman python
col Richard reaching out to the Future that's great wonderful that's it Scott thank
you muchl thank you so much and thanks to the astronomical league for uh
supporting all these uh star parties and doing all that they do for astronomers all over the world so and thanks you for
your great Support over the years Scott we couldn't do it without you oh likewise likewise by so thank you very
much sure thank you all right so we are going to go to a 10-minute Break um time
to stretch your legs uh get a sandwich get get something warm to drink and
we'll be back uh with more Global Star Party number 42
thanks
for
for
for
e
e
e
e
e
e
e
oh
for
well we're back after our 10-minute break here and uh I wanted to mention to
you that a lot of the presenters on our programs have also written books uh most
notably here on the program tonight is uh David Levy and David AER uh behind me
here um you'll see uh David Levy's book uh a night watchman's journey and this
is um this is his uh personal story of uh of uh Triumph and and challenges and
uh you know all the uh Adventures that uh David Levy has taken in his life uh
so it's it's a it's a great book a great read um and then there are a couple of
other books here uh now both David Levy and David ier have written many books um
and they're all worth a good read but uh um this is one of uh uh iker's books on
Galaxies here uh this was uh um this
explains many of the complex uh aspects of galaxies black holes um you know star
formation in galaxies that kind of thing and uh it is just a spectacular book
with lots of great astrophotography in it as well um a presenter that comes onto our
program regularly is J Jerry Hubble this is his book on remote observatories for amateur astronomers he also has a book
on scientific Imaging from the Patrick Moore practical astronomy series um so
that that's something to be watching for and then behind me here is um Cosmic 3D
clouds um by uh Dave eer and uh Brian
May who is a league guitarist for Queen um uh Dave Iker and Brian uh have an
incredible collaboration where you can see uh a lot of your favorite objects in
3D by um using this uh kind of uh I know that there's a technical name for it but
basically I cross my eyes and look at the images and can see them in 3D there
are a pair of special glasses in the back of this book which you see right here to help you do that and it is a an
amazing Voyage in itself so joining us from Halfway Around The
World is uh deep tea gam deep tea is uh from Nepal uh she uh is uh you're still
going through high school I know and uh um she is a big inspiration to uh not
only to us but uh to all of her friends uh back in Nepal that are involved in
astronomy she also belongs to uh the major U astronomical Association in
Nepal as well and uh deept thanks again for coming on to our
program hello everyone and thanks for having me again
here last time I have talked about
the Asom so I think about to take about the
why not to take about the history of astronomy so this I have studied about the history of astronomy so like
astronomy is the oldest of the Natural Science
and getting back to Antiquity and with its organs in the religious and
mythological and astrological practice of prehistory and a few centuries ago in the Western
World see astrology and astronomy and Early Astronomy involved observing the
regular patterns of the Moon of visible celestial object and especially the sun
and moon stars and naked eye planets and an examples of this Early Astronomy
might involves a study of the changing position of the sun and Al the horizons
are the changing appearance of stars in the course of the year and which will be
used to establish an culture or ritual calendar in In some cultures
astronomical data was used for astrological phenomenas and but ancient
astronomers were able to differences between the star and planets as star
remain relatively fixed over the centuries while planets will move in appreciable amount during comparatively
short times and talking about the early history and early culture cultes
identified Celestial body with the gods and spirits and they related with this object and their movement to phenomena
so the rain drought season and tides and it is generally believed that the first
professional astronomer were priest and S is the for example the M was the pr
and that their understanding of the heaven was SE is they been and Hance
astronomy ancient connection to what is now called astrology inent structure
with astronomical align alignments and SES and probably fulfill both
astrological and religious functions and the calendar of the world have usually been said by the Sun and the Moon
measuring the day month years and WS of importance to Agricultural Society in
which the Harvest dependent on the planting at the correct time of years
and as Nepal is also an agricultur country so it is most necessary um to
know the harvesting and defending the planet and the cor the most common mod
calendar is based on Roman Calendar which divided the year into 12 month of
alternating 30 and 31 days of pce in in 46 BC that is Julius caser instigated
the calendar reform and adopted a calendar based upon the 365 uh one upon
one by four days your length originally proposed by fourth Century BC Greek
astronomers and uh talking about the Mesopotamia and the origin of Western
astronomy can be found in Mesopotamia and the land between rivers and tiges
and ofus where the ancient Kingdom of Summer and asies and BMA
and classical Source free quently use the term CL Dan for the astronom of
Mesopotamia were in real reality PR scribe and specializ in astrology and
other form of deviation and all significance um and the in the Egypt
where this astronomy is origin the the precious orientation of the Egyptian
pyramid efforted a lasting demonstration of the high degree of technical skill skill in watching the heaven attend in
the third millennium BC and it has been shown the pyramids were aligned toward
the full star which because the Precision of the Equinox was at the time
and to one of Fain star in the colle conation of drao evolution of the site
of the Temple of amund at kak taking into account the change over time of the
OB of the eclipse and uh is has shown
that the great temples have aligned on the rising the mid winter sun and the
length of the cor town is sunlights will travel will have limited illumination at
other times of the year and um astronomy uh Early Astronomy has played a
considerable part in the religious matters for fixing the date of the festivals and determining the hours of
the night and titles ofing the in phes of the sun moons and
star and the rising of Cyrus and Egyptian sovet Greeks and that sis at
the beginning of the in IND ination was particularly important uh point to fix
in the year calendars so this all the information I have collected about the
history of the astronomy uh so thank you thank you very much I think here the
uh the uh background noise of
Nepal this true you can are do you have uh is there the window or something
nearby the uh uh to the street of Nepal
there yeah yeah okay yeah very cool very cool gives us a
little International flavor there that's awesome okay um uh up next uh we have Cameron Gillis
we come all the way back from Nepal to um uh Seattle it's Seattle Washington
right Cameron yes and you've been having some clear
skies correct yes and in fact having another one today been really really lucky great
great thank thank you for coming on again tonight and uh thanks for becoming a regular on the global star party oh
thank you Scott thank you very much so um yeah no basically I I I really um U
you know what you've been doing here Scott is fantastic uh I love you know the the uh the the the mind or the the
you know the the whole team of of amazing astronomers and there's just a a wealth of and and a dynamic group here
that's uh just really wonderful it's really nice to be able to share and collaborate and uh and uh and and share
in this experience so thank you for setting this uh this platform up and uh and really uh it really motivates
everyone and it's it's it's fantastic so thank you Scott that's great that's great well you know it's the group here
that makes it all happen so it's awesome I love it too yeah yeah so uh yeah yeah
actually it caught me a little bit off guard but it's okay I want to share a couple of things so what I've been doing
is uh we had this swath of amazing weather in in Seattle and um uh starting
last year uh I kind of uh I actually went from a manual uh telescope to a
go-to telescope and um and uh and I uh started to and I also bought Sky Safari
and I started to uh come up with a master plan where where you know as part of my
journey here going from visual observing to astroimaging uh I'm I wanted to do a
visual Sky survey of every object that I can see with an 8 inch
schen and uh and uh and then basically start to catalog and and uh record all
the different objects uh that I could see um you know and and and what's
interesting about that is uh like I was saying before we started
the the star party here is that uh as a visual Observer you notice you know the
surface brightness is a huge thing especially with I have bordal six to bordal eight Skies so uh what's
fascinating is some of the fainter magnitude galaxies that are small um
actually come out more uh more pronounced and they're much easier to find than some of the let's say 10th
magnitude even ninth magnitude larger low surface brightness Galaxy so so I I
wanted to kind of do a broad brush um and and look at you know what are the
things that are observable uh with with that aperture and then also identify
candidates that I can use with a smaller for example an ed80 um you know if I want to just pop
out and see uh see some skies and see some different objects in different constellations so I kind of uh
constellation by constellation I made observing lists and uh let me actually share my screen here I'm doing this all
on my smartphone so let me uh let me just give me a second here gonna open up uh Sky
Safari there it is okay let me share my screen
now start now Okay so can you see my screen
yes okay so basically if I turn this off
okay so if I just I have many observation observing lists so I have
best and brightest is what I call it I keep an adding at uh you know I have
510 11 objects in my best and braist but I for every for every constellation I
have everything down to 13th magnitude um which is within grasp of
an 8 in um and um you know Stellar magnitude 14 but but
visual magnitude 13 and you know I did that mainly because uh like I said some of the smaller galaxies you can actually
pick out um anyhow so I did that across and you can see every constellation has a number of objects in it and what you
can do is uh I got all the way down to uh last night actually I finished up
on virgo this was a big one 290 6 objects it's always very intimidating
and I have to admit I had in my past I had a I had a um an 18inch dob and uh
and you know it's quite overwhelming uh you know you start to do that but with go-to technology I'm actually seeing
combing through a lot of objects that I wouldn't never have normally found or never wouldn't have discovered uh if I
just you know uh unless I had many many nights uh uh but in Seattle we don't
have that so so now I'm able to actually categorize and uh oops did I stop
sharing let me just uh let's see what happened can you still
see my screen uh not yet okay it looks like it
just uh timed out give me a second share my screen again okay let's go back
to okay now you can see my screen now right yes okay so yeah so any know so um
I I started really it's so fun in the Journey of Discovery I mean we always look at an image a lot of familiar
objects and and that's cool I I love it and and that's nice especially if you're just you know trying to um uh you know
do quick looks and stuff like that but uh or we want to study something in detail and that's what I want to get to
but what I wanted to do is kind of see everything I could see and I started going through the list and if I look at
for example the best and brightest and I go
and I highlight it you can see uh you know I turn off
the uh the equator here we go equatorial mode if I zoom back out you can see that
the Southern Southern hemisphere is a big hole of course I can't see the LM large
and small so you know I'm jealous of uh Caesar but uh one of these days I'll get
there um but uh but I've basically started categorizing there's still a bit of a hole here around Virgo
uh because what I've done is I just finished observing them and then what I do is I go through and I highlight those
ones that I if I have a good uh observation like let's say we go to uh
maran's chain here and I just click on on this object and I go okay let's uh show the
observations so this I made on Tuesday nice bright oval with bright core right
for example very very crude descriptions and then sometimes I say faint patch or whatever
I have a number of things and I can do this efficiently because it does Auto autofill as I as I uh as I start
selecting those so if I choose a constellation H let's
choose uh sorry about that go to observing list and let's just choose best and
brightest for now and I go uh unobserved and what I do o sorry
highlight objects yeah that's fine and what I'll do constellation by constellation I'll go okay so let's say
I'm looking at this galaxy here I click on it it's a magnitude 11.8 and I go
okay I'm G to make an observation so I go create new observation I say let's
say faint faint patch or something like that or whatever right and then um and then I
go down here and I let me just turn off
my sorry yeah that's good enough and I'll just go
enter and then yeah there we go and then I log the uh the seeing let's say it's slight uh seeing
level two I choose my 8 in and then it goes away so what you can
do is you can you know methodically uh go through item uh you know um object by
object and then it starts to take it out and that when it's rainy time you know which happens a lot in Seattle I can go
back through that catalog and start identifying which are the good ones and uh which are the uh you know the ones
that I want to kind of say that's there's no chance of me seeing that based on conditions and then I can
already make a good night's observ so what I'm going to do is I'm going to finish this and I've just finished a
Virgo like I said I'm going to start to go through and identify best and brightest there that will connect
everything up and like you say after about a year of doing this uh I just finished it uh and I started in booties
and then I I finished in Virgo but I still have to do uh some of the other ones once I've done that this is all
setting up to my my next plan which is you know getting an Imaging uh system
going to have ed80 uh with you know the your um PMC
probably the exus 2 and and then I'm going to start to uh you know
constellation by constellation I'll set up image sequences and start um you know
categorizing all these through Imaging and I like what Jason gonel did you know
start to get a little deeper and see the fainter uh fainter galaxies uh in the
behind and so anyhow I wanted to just share uh kind of what I'm up to and uh
and I'm just wanted to also say that I was really happy to make it through a survive Virgo so that was that was
pretty overwhelming it's Galaxy season right so it is Galaxy season I see galaxies all the time now everywhere
like when he showed me the David iker's galaxy book I was like oh yeah oh you gotta get that
yeah send it to David he'll probably sign it for you so that's awesome yeah
yeah uh yeah also I wanted to mention too of course and David Levy touched on
it earlier uh it is the time for the larid meteor showers so uh you know the
U uh 21st and 22nd will be the I guess the peak of that um but uh that that's
that's awesome and we have uh also uh Earth day this week um that's being
celebrated around the world and so it's our it's our favorite planet that we
just happened to live on so anyhow um let's go uh next to um I think
Molly Wakeling Molly are you uh are you Imaging at this point or is it dark
enough there it's not quite dark enough to uh
to do any deep sky but I do have the moon all right it's so bright you can get it even during the daytime and it
looks nice so let me uh switch over here okay um yeah so uh this is through my
11inch migrain on my Paramount Mighty yeah and this is all my
monochrome zwo 1600 camera I think the uh the luminance filter is what's
currently in place um but it doesn't particularly matter since it's monochrome um and we've got ourselves a
um a we're almost at at a first first quarter or are we are we at first quarter um it's first
quarter yes today is first quarter um yeah so it's almost exactly 50% filled
now um let's actually the imagees flipped right now so I'm actually G to
go um let's let's flip that around so it's more normal let's see uh yep that's
right okay so this is how you would see it on the sky um bring that video up a
bit that's like the ears of the rabbit are showing oh yeah somebody I I did finally
like like figure out uh some of these things that people see in the moon but I
didn't I couldn't really see them until I was in the Southern Hemisphere and the moon was slipped over right very weird um yeah the moon
was the Moon is upside down there uh all right so um we've got some cool features
here over so see can you see my my mouse there we go um this is mar
chissum and so so Mar is the Latin word for for C or for C's plural um Maria
being a a single version of that and um you know because when people looked up
at the moon in in ancient times one might imagine that these are seabeds so Mari chissum I don't remember what
chissum means uh um but it
means yeah a sea of crises as one might might guess that
people like name these things pretty creatively yeah um this one here we've
got uh Mar s seren see if I can pronounce this serenitatis yeah this
Serenity sea of Serenity um and then of course we have Mar tranquillitatis or
the Sea of Tranquility which is the General site of the Apollo landing and
if I can remember from I've hunted down the site before now obviously you can't actually see the landing craft from a
telescope here on Earth but let me zoom in and show you roughly where it's
at get my bearings
here yeah all right so here is the Sea of Tranquility and we we can't see the flag
we cannot see the flag unfortunately um here's this uh this
channel that connects down to um another uh Maria below and you kind of get this
uh curved shape here and right about um where it's got this uh this Inlet here
um the poan site is is right about right about here where my mouse is uh to the
right of of a of this crater that you can see here um it's approximately here
uh in the nice empty Maria area uh now even with the even with
powerful groundbased telescopes you cannot see the Lander or the flag and it's it's even difficult to spot with
the lunar reconnaissance Orbiter the uh satellite in orbit around the Moon that Maps the surface um but it has been
spotted and so have um like other craft that have crashed into the the moon uh
you know you can SP spot the debris fields and stuff like that um so it is
it's it's not visible from the ground on Earth even with really visible really large telescopes but uh with the
satellite around the Moon they can pick it up although it is still small and hard to detect even from there space is
Big y'all it's awesome it's awesome okay great okay all
right Molly well that's great um I'll see if I can get a uh a deep Sky Target
up um before the end of the broadcast here okay all right so we're going uh
we're going to have another presentation by John Briggs uh John uh uh was um uh
putting together some programs uh the second program he sent to me is is
longer okay uh which is okay um but uh
uh before we go go to that I didn't I wanted to check in on Caesar Caesar is
there something else that you'd like to show us just before we go on to uh to John's program uh yes yes I have I have
let me show you that I make now I now I am taking pictures of uh ETA Karina
nebula but this is beside of a
wiing let me show you how each picture
there are the live the the live live pictures now
wow yes and he now here is the nebula
because you can see the open cluster that is I think that is 3 three five2
the number of NTC of this but um
let me check well here you can see now how the
the the the welding is moving yes and in few minutes I'll be
clear this area with here it's mostly here the the nebula is in this
area I can try make a a decent not decent well
comparing with the picture of Jason or Molly my pictures are horribl
but you know Caesar what you show people is how they can use uh uh small
telescopes uh and do astrophotography from the city you're in Buenos Aries
okay this is a very heavily light polluted city okay and you're still
making images and um so it's good it's good
yes yes it's something for encouraging people enaging people to to make this
right all cameras cell phones or you know you can see how how it's moving the
sky not the well the sky and you can see
how this part of the Wilding that is in this direction the south south East
yes and exploring the area where
the is okay okay all right so we will run um
uh John Brigg's second program here this is about y's Observatory and uh something that's near
and dear to my heart we have yuris is a charter member of the alliance of
historic observatories which is a new organization dedicated towards uh you
know promoting and preserving uh historic um observatories not only in
the United States but around the world and so this is uh this is our mission um
and uh certainly the uh y Observatory and the UK y Future Foundation is a big
success story on uh being able to save uh one of these observatories that very
nearly met its demise not only once but a couple of times so um and and I know
that John worked there John do you want to talk a little bit about um I'll just
comment that um I prepared this presentation for the antique telescope
Society last year uh which has a membership I think of about 220 people
uh folks especially interested in historic observatories and old telescopes and history of astronomy uh
so this is another history and Hardware oriented presentation But it includes a lot of cool pictures of historical
artifacts that kind of came out of the woodwork of y's observatory in the
course of University of Chicago transferring the facility to yur's
Future Foundation so um I just thought that folks here would enjoy seeing this
because yeres is a wonderful historic place so thank you for letting us share
it Scott thanks John okay so let's see if I can do this right here here we go
and let me share this in presentation mode
and share sound uh I will just in a moment but let
me share the screen I I can show the pictures of an
historic uh an historic uh hi everybody this is John Briggs in
New Mexico and I'm uh thank you for being here uh I'm going to speak on a
brief report on the status of yor Observatory with some highlights from the inventory of 2018
I was inspired to offer this uh presentation because I had a chance to visit y uh in September of this year and
learn I'm sorry did I did someone say they could
not see this okay let's start
again let's start again yeah um Scott it's uh not coming
out out on the YouTube channel it's not the video is not playing it's not playing on YouTube we're just see well
we're just seeing you see okay all right
let's make sure there we go that okay
yeah hi everybody this is John Briggs in New Mexico and I'm uh thank you for
being here uh I'm going to speak on a brief report on the status of y's Observatory with some highlights from
the inventory of 2018 I was inspired to offer this uh presentation because I had a chance to
visit yeres uh in September of this year and learn a little bit about what's
happening with yur's Future Foundation although my business there was very limited I still learned uh interesting
things that I figured you would enjoy uh hearing
also back in 2018 when the university had decided it
was closing y's Observatory they asked me to come and do
an inventory of things in the building and I went nuts on the project I took a
lot of pictures and so today I'm going to draw upon uh that archive to show you
things that I'm sure will interest you that were many of which were never
shown uh uh normally on on Public tours or anything like
that in the very beginning of my inventory I included this little quote
from the late Don UST Brock he had taken me aside one
time back at yurys and he knew how interested I was in his history but he
wanted to encourage that to with anybody who who shared the interest and he said
history of astronomy is astronomy too and he that was his way of encouraging
me as strongly as I think he possibly could and it's been an inspiration to
have heard that from him so I thought I would share those words with you all
too now when I did the inventory uh this is one of the pictures
one of actually many pictures of bricks that I included with it because I'd
actually been taking pictures of bricks there for some years out of
concern because the these bricks are in the Dome of the 40in on the upper indoor
balcony but look at the powder building up in the floor the bricks were
deteriorating it appeared that the deterioration of the bricks was accelerating and although University of
Chicago had done a lot of of of serious work on masonry all around the building
man I was worried about how these bricks were deteriorating and what that meant for the future of the
building well um it's good news as I'll
explain the good news as this newspaper website
headline explains the Yury Future Foundation celebrates the donation and
takes ownership of yur's Observatory and there's Diana Colman uh the president of
the foundation on the front steps of yeres um and Ed strubel the longtime
caretaker at yeres well Diana and her colleagues in the the foundation are uh
pursuing the brick masonry problems in the building very
aggressively I want to show another picture of Ed strubel uh because he
really represents a very important continuity at yur's Observatory um he
was hired in the early 1990s when I myself was back there on
the staff and he continues there as the uh the site superintendent with York's
Future Foundation um the university uh employed him right through the
transition and he's really impressing me with the great Insight that he has on
just about everything going on there at yeres through this transition it's very
fortunate here's a picture that Ed sent me recently showing the uh refurbishment
of the masonry going on inside the Dome that same area where I took that picture
sometime earlier so they are really going to town doing right by restoring
the support under the main Dome and thank goodness yur's Future Foundation
is able to do this as a first step for the future of the
building in many places the uh brick replacement is going right through the
wall from inside to outside they can't finish all of this uh before uh cold
weather so the work will continue also this
spring the specific reason I was there in September was at the request of the
foundation to talk about the future of the Bruce telescope shown in this uh
great old drawing the Bruce astrograph was made by Warner and suy um for uh
Edward Barnard and it was most famous for the Milky Way Atlas that Barnard uh
recorded actually mainly taking plates at Mount Wilson Observatory when the
telescope was brand new but this instrument continued to be a Workhorse for many other astronomers including
Frank Ross who used different optics for even U more extraordinary pictures of
the Milky Way a number of ATS members will
remember having seen the Bruce mounting um still in use in the early
1990s uh here in what we call the south building or the laboratory building on
on the grounds of yeres uh this is essentially the same location where
Barnard had it set up in the early 20th century uh but when we saw it at our
second annual meeting it was in the dome uh closest to the camera but in more
recent years uh staff there decided to take it out to put a more modern student
friendly telescope in the dome and since then it's been in storage but the idea
now is uh it can be refurbished and put back to
use here's the Bruce pillar uh like so many interesting things uh in storage
under the gigantic floor of the 40-in
refractor and right beside it uh the astrographic equatorial head it's a very
heavy instrument now fortunately it has been set down there quite tenderly um so
I think this thing is actually in in still in very good condition um because
the the yur staff moved it here uh not not so long ago and mainly it's just a
matter of putting this equatorial back together
again unfortunately not so much survives of the original tube assemblies that
were carried on this mounting uh these parts were part of the 5-in refractor uh
guide telescope for the Bruce the the objective lens unfortunately is lost the
10-in Optics made by brashier for the Four Element uh petsville of
astrographic lens uh were shipped to Greece now Bart freed and myself and
others have been uh working to get those Optics back from Greece and now because
the foundation is interested in refurbishing this instrument the motivation to getting the Optics back is
stronger than ever the 10-in Optics are gone the guide
telescope Optics are gone but uh the 6 and a/4 in Voit launder lens Optics that
I believe went with this tube fragment turns out they
survive thank goodness they were labeled when they were taken off and put away
and it says right on it front lens for 6-in Bruce telescope removed and stored on January 9th
1953 and here also it says back element but there's actually two pieces of glass
in the cell for the Voit launder lens um but optically everything survives for at
least this component of what was originally a three tube astrograph
and something I did not realize until very recently turns out it was the 6 and a/4
in Voit launder lens that recorded one of the two exposures used by
Barnard uh to to discover Barnard's star the high proper motion star the highest
proper motion star in this multiple exposure um uh graphic here uh showing
its changing position from 2007 back to two to
1991 uh the companion plate for the discovery of this fast moving star was
from the Willard lens at Lick Observatory um that had the same focal
length so it was plates from two different telescopes that actually were
blinked against each other with a Zeiss Bling comparator by Barnard another instrument that does survive at yeres to
discovered this particularly famous star so the fact that the the the the Voit
laer 6 and a/4 in Optics survive at yuris and can be
resurrected um and can and can help tell the story of the discovery of this
highest of all proper motion Stars well it's really cool and makes me quite
excited with the prospect of refurbishing and reactivating the
bruise now of course among the smaller but very famous instruments associated
with yeres that we are all going to be curious about was the Kenwood refractor that
here uh hail himself had it in his personal backyard Observatory that was
integrated into yur's Observatory as it was built the 12in uh
brasier lens Warner and swayy mounting canwood uh
refractor and here it is after it was installed in the north
Dome uh at yurys and it served as a Workhorse for students and many many uh
different projects but of course with the passage of time it was extensively
modified and uh it will be an even an even bigger project to refurbish the
Kenwood to restore it to Service uh to approximate its original form as seen
here but it's still quite possible in fact here's the base of the
Kenwood in the South Dome of the lab building on the south lawn of yeres we
can't get the whole instrument one picture because it goes right up through
the ceiling uh Beyond uh uh to an observing floor that will show you the
scene up above next slide and here's the equatorial to the
Kenwood sometime in the 1960s it began to carry a Schmid camera
with about an 8 in diameter corrector plate and a 16in primary obviously this
instrument hasn't been used in a while uh folks were actually using it in the
uh early 1990s but it's sorely neglected now but
it hasn't been forgotten a side view of the Kenwood
equatorial it's a massive instrument um the Schmid cam camera
above but try to imagine hail's excitement his thrill as a young man
when this instrument instrument um was new in
1891 and in his backyard Observatory what a historic
instrument Hill's family was wealthy so he had not just one 12 in brashier
objective but two one on the left for visual work corrected for in for yellow
observing in the yellow green and the one on the
right hail's family was wealthy so he had not just one 12in brashier objective
but two one on the left for visual work
corrected for and for yellow observing in the yellow green and the one on the right corrected for photographic work in
other words corrected for blue light sharpest focus in Blue
Light see this one is labeled
Visual and this one is similarly stamped on the lens cell photo for photographic
of course here's the original Warner and
suy focuser a beautiful piece of work not everything uh survives of the
Kenwood but enough does to indeed make it practical to resur the
instrument what's a little confusing perhaps are these tube
assembly sections under the floor of the 40 in all from the Kenwood we can count
them 1 2 3 four five how do you get five long 12-in refractor tube sections for
one telescope well the reason is sometime in the 1920s fcker
re-engineered the telescope and they set aside the original Warner and suy single
Barrel tube and they made a new one like a double barrel shotgun the gray tube
sections there's actually four of them there though you can only count three in this picture those are the fecker uh
tube assemblies that allow using both uh Visual and photographic objectives
simultaneously here's the center casting that fcker built uh looks like it's made
out of aluminum of with making the double barreled uh design obvious and
unfortunate thing is that the Warner and suy Center section for just one barrel
which would have been an iron casting unfortunately does not survive so that will make it harder but
still not impossible to resurrect the instrument in a single tube form
what the Kenwood is especially famous for is hail's early work on the sun with
his Spectra heliograph made by rasher shown here in which hail and his
associates successfully recorded monochromatic images of the Sun in uh uh
uh h K uh blue light and I presume also
ultimately uh the red light of hydrogen Alpha but this was the this this
instrument um unfortunately has long been
cannibalized but it astonished me being back there recently dur doing the
inventory to actually finally Discover at at least an original fragment of
it wow now believe it or not this
thing is is is a highly modified
but unquestionably um a surviving part of
hail's original spectr helioscope pardon me spectr Helio graph the scope is when
it's designed to look through this one was for photography um and I did not see this at
yeres as an employee there starting in the early 90s but when I went back uh to
do the inventory it had materialized on a shelf I don't know where it had been
in the meantime but I feared this is likely the only recognizable piece left
to the hail spectr heliograph here's a view of the back of
that same assembly it's actually the plate holder and there's uh the moving
slit that would have been right in front of the glass photographic plate uh small
details in this mechanism uh correspond perfectly with some of the
early photos and drawings of the instrument there's no doubt in my mind at all that this this came from uh the
original although what we see um has considerable evidence of modification
along the way we don't have time but to touch on a
few things from the yores inventory uh
there's still a tremendous amount of stuff at yeres but one place the typical
tour certainly did not get to see was inside the yy's Vault um here the door
is open let's take a peek inside I inventoried
everything here's the door open beckoning Us in um it it's very interesting to
consider the I the the forethought that that hail
had including a vault at the observatory
anticipating that certain things were going to be so important maybe data or
maybe uh valuable Optical Parts whatever just the the necessity of having a vault
in an observatory um this was no afterthought I'm sure it was there from the very
beginning now by the way as we step inside there's
a key hanging from the inside of the door with a screwdriver but a little tag
says warning this key is for changing the combination only it will not get you
out if you are locked in do not experiment and I'm not sure whose
initials those are on the tag wow
there are Curiosities inside what is
this notice there are concentric circular
patterns on the top of this looks like a piece of
ice uh with frost but no that's not what it
is here's the backside and you can see
there's a tag on it let's check out the tag it reads fragment of the 36in disc
intended as a photographic correcting lens for the 36 in object glass of the
Lick Observatory which exploded in the grinding wow given to e barard by Elvin
G Clark at Cambridge Mass in 1893
wow how about this thing maybe it's a
meteorite um perhaps not a meteorite with a thickness like that and
a curved Edge I'm sure many of you remember how
in the very early days of yur's Observatory way before the expedition of
Mount Wilson there was a solar telescope set up out on the lawn the horizontal
solar telescope this was uh supposed to be an improvement from the heliostat
room in the upstairs between the North and South Towers where the thermal
conditions really were not so good for solar astronomy so they built a
horizontal solar telescope out on the lawn but a very bad thing happened I
don't know how whether it was an electrical spark or whether it was
sunlight uh off a primary mirror it's a pretty cloudy day who knows how the fire
started but man it
burned uh the Optics were not exactly uh low thermal
expansion let's let's read the tag that survives with the artifact it says Mr
Kyper these quote paper weights are fragments of the seal stat mirror that
was destroyed when the temporary seal stat building south of the observatory in the early days was burned
MRC well that's Barnard's niece Mary R
Calvert uh she was the one who co-authored the Milky Way Atlas with
frost after Barnard's death it wasn't published until after his death he was
such a perfectionist he couldn't he couldn't uh finish it he struggled so Holding Out
for the most perfect reproductions of the plates but Mary Cal Calvert uh and
frost did Mary recorded many things around
yuris um sometimes with handwriting sometimes with a typewriter uh after her uncle was
gone and if Mary's uh testimony wasn't enough on the back of the fragment
there's this tag part of mirror destroyed by fire in first horizontal
costat telescope south of York's Observatory but at the very top there
EB so that there is the handwriting of Barnard himself
wow what about this thing well it relates to lunar
atlases um there's quite a cult following for lunar atlases in the
earliest days of the Space Race uh but here's an artifact it says
on it 5 in diameter objective lens acromatic and Brass cell used as
projector lens for rectified lunar photographs at yur's Observatory 1959 60
then at lunar and planetary lab University of Arizona 1960 on original
property of yuris borrowed from unknown telescope focal length 215 CM about 85
in well that was the handwriting of EA Whitaker the famous expert in lunar
nomenclature British born astronomer who lived till
2016 and nearly a century uh of life and
he returned this lens uh towards the end of his life to yuris um because he was
the one who remembered where it had come from
wow he said it was from an unknown telescope but perhaps some of you will
agree with me the characteristics of the cell uh speak volumes the index marks
there for the retaining ring so simple the nature of the threads the way it's machined it screams fits to me of all
things Henry Fitz or maybe burn or maybe Henry's son Harry
uh who knows but it's not a Clark and it's not a Warner and S um sure looks
like a fits here's the side view you can judge
for yourself I have a 6in uh fit subjective and it occurs to me one of
these days I'll carry it to yeres and compare it uh side by side to help uh
convince myself that this lunar cartography related lens is
certainly a fits but that's sure my hunch let me know what you
think this box was clearly labeled to forewarn us what we're going to find
inside but unfortunately we know nothing else about it it seems quite clearly a
Warner and suy style cell uh some people might call it a brusher style
cell um it may have a very long focal length I didn't have time to check that
when I was doing the inventory at all there was just no time it may have been
mounted piggyback on the 40-in refractor and it may have a focal length similar
to that of the 40 in and therefore it would have been an a lens to estimate
the quality of the seeing as was often
used uh during Parallax work um uh as
plates were recorded was the seeing good on a particular night it was judged by
looking at the stars through a very long Focus finder in effect typically with no
tube so I have a hunch that's might be what this is but only if it has a very
long focal length when one of these days we'll have to check what about the ship's wheel that
came also out of the vault in this case it it there's a
label wheel removed from Bruce building January 6th 1966 when building was
raised wheel was and then it goes on on the other side uh but what this wheel
did this was the Dome rotation wheel H so barard and others had their hands um
um a lot on this wheel in the course of their very long exposure photography
keeping that Dome slit aligned with the slowly tracking astrograph this wheel
rotated it cranked the Dome here's a box that maybe more than
almost anything else I found at y during the inventory kind of caught me off
guard and blew my mind this did not come out of the Vault this was in the empty
or well nearly empty office of professor emeritus Lou Hobbs who was a
spectroscopist high resolution uh uh spectroscopy among other
things the Box though says Michaelson take a look at what's inside
it says 3 and 1/2 in Gold I had my suspicions when I read this but my mind
was blown it's a defraction grading one of
the few examples surviving of those ruled by AA Michaelson the first
American to be awarded a Nobel Prize in physics wow and it was there I had no
idea it was in the YK building um until I did this inventory
Lou had it in his office well I'm already over time and I
have to wrap it up we could go on and on talking about artifacts at yeres here's
a picture from some years back when I was visiting with my solar physicist
friend Steve tomek from high altitude Observatory and uh we were measuring the
lens and uh well first we cleaned it you can see how fil it was but I have
finally just a few artifacts relating to the mighty yuy lens
itself here's an un an unusual view of the lens with a camera handheld inside
the tube looking out through it uh through it I'm I'm holding the lens
through uh holding the camera through an open port as part of our
cleaning and here as found in the vault uh what I found uh related to the lens
two 60° prisms cut from sample squares of crown and Flint glass of the 40in
lens and it goes on and on and there's a test report inside there too let's take
a look here's the test report from the uh National Bureau of Standards dated
1928 it's giving um the uh indices at very standard wavelengths for both the
crown and the Flint uh lens types glass
types and here are the little bitty pieces of glass uh that allowed those measurements
to be made by the National Bureau of Standards so uh just it's very
interesting and fortunate that these things survive
well I'm out of time um it has been cloudy above y's
Observatory for a while but I believe uh we have uh uh bright things coming in
the future happening at yeres the sky is going to clear uh the yeres Future
Foundation is is doing and will continue to do very good things I'm I'm really
very optimistic about that so uh I look forward to reporting future news from
this beloved Place uh as as we have it thank you for your
attention wow that is a great presentation
um John that that was uh wonderful is there is there anything else you'd like to to mention about your your
presentation of the yuris observatory and your IM inventory there well I um I
I can go on and on uh talking about things there especially with photographs
but I think I've abused your audience enough for one night but I I hope people
enjoyed uh uh seeing some of that stuff that isn't normally seen but obviously
it should be and it's easy to become wonderfully interested in history of
telescope technology so there's uh there are many opportunities for historical
preservation all around the world some other people here already have been
showing pictures of historic observatories close to their homes those
types of presentations are of intense interest to me and to all other members
of antique telescope Society so to become engaged with uh history of
astronomy and historical preservation is is simply another opportunity for
amateur astronomers um at a Grassroots level that's the way to attack these problems
individually closest to home so thanks for your attention everybody thank you
John I mean you're it's wonderful to have a presentation like this because John Briggs is really one of the few
people in the world uh that could uh describe some of these things to you and
in fact this inventory uh your Observatory had it not been uh shared by
John might have very well been lost um so it's very very cool this is our this
is one of the uh the common or the threads that reach back to our history
of modern astrophysics and uh um you know and the way that it was developed
and the tools and the gear and the people and all the rest of that stuff that made it happen so John thank you
very much that was awesome my pleasure my pleasure folks that was really great
okay um let's return back to the astrophotographers
um uh who has uh who's has something up live right
now uh I have a so I just rejoined
um yeah I um rejoined briefly and if we're looking for something rather quick
um I can go I can go over a couple of things that I've been uh working on um I
think a good place to go might be um a few pictures that I've taken
from uh spring solstice uh does that sound like a good idea
or yep uh all right let's see I can and this this will
be maybe two minutes sure that's fine yeah bring the solices are a great time
to go Aurora hunting and so let's see if I go to just
share my screen because that's what I'll do um so this is a page I put together a
web page of galleries of a lot of pictures you've seen some of these um
spring solstice great time to go to a place and
you don't have to go all the way North to see the Northern Lights so this is a uh
this is a good example of that um now they happen to be we happen to get a
good storm during um the uh Solstice in 320 so all I did
was aim my camera North and this is an unmodified camera so you can take your
regular DSLR mirr less camera go to one of these sites aim North and
um if Aurora is happening you will catch it and in this case we had a number of
be we had a lot of beautiful colors that um took place this particular oh yeah
Aurora I'm gonna see if I can forward through yeah I can
so lots of just taking lots of shot in point O barky's Lighthouse if you're
ever in Michigan you go to the thumb this is a great it's about a bort 3 dark
sky a great place this red light is there there is a red light that shines
in that direction leaving these Shadows um you can see that the Aurora was in
the background um so let's see I went the wrong way of course CU you know why do
something okay okay so so if we keep skipping through here
this is these are some of the shots that I took I tried so as soon as you're not
facing north the light here and some of these are on process this is about what you see Milky
Way wise maybe not quite with the colors but the detail is there in the portal 3
sky and those are the lights from across Lake hiron in Canada so
um that's uh these are some of the images that I took there and they they
get more impressive because this I was there at 3:40 in the morning you want to do asro photography sometimes you got to
wake up early in the morning when the events are taking place and this was
3:40 a.m. I showed up and I looked North and this thing these things were
happening and so different exposures um different shots not every
shot's perfect the first time around so you just have to keep shooting turned
over the Milky Way core was Rising this is what I was here for um found out
there as Aurora try to dark you get some interesting images here if you just go
you don't do a long exposure you miss a lot of detail but you do you kind of see
how dark it is out there even with those lights from the lighthouse um then you process a little
more and you end up with a better image um man you end up with something like
this so um you can look at um and I'm trying to
remember the site it's um spaceweather.com I just looked at a
presentation by an naid uh Aurora Chaser uh Mary Beth kazinski who um had has
fantastic pictures of Aurora if you haven't heard of her um she takes she
was out taking pictures in Minnesota the same night I was out here and I think a
week before she was at another location in the thumb um there was Aurora the
week before as well and she got some pictures there um but uh you can check a
bunch of different sites to see when the Aurora might be
visible and in addition to it being clear um the KP index is just one factor
check out um there's a setting called bz I'm still learning about it there's some
other factors that tell you the real nature of the storm and if it's going to
happen and so if you or you just go one
night and you see you can face North and get lucky um I wouldn't recommend trying
that so yeah that night was clear and there was Aurora so it was a it was a
beautiful night that's a nice shot which one this one here go back
one there you go yeah this shot one of the better ones
that I took U with the Milky Way going over to Lighthouse this is uh and I
ought to process it and straighten that Horizon out for you but um I did have a
couple where I like this I think this is where I straightened out the Horizon this was the uh that was the fixed
version of the shot right there and this was the over you can overdo your astrophotography too you're out there
and you're trying to do these night images you have to be careful not to
overprocess your images on Instagram it may look great
but on a bigger computer you begin to blow lots of things out like if you look here I've got some detail in the
lighthouse there's you know the light is pretty bright I think that's the same image and I just tried to overdo it and
I lost it's like I blew away the whole Lighthouse there so so be careful with
your um night images and make sure that you don't just lose them this is a sort
of a real real time shot and I think that's me taking the image right there
um this is one I I had forgotten I'd taken um I kind I kind of like it actually but it's a uh there's the
Aurora I think this is maybe a 30- second shot this is kind of what it looks like facing away from the
lighthouse it's like me turning around from here and then moving closer to the
lighthouse and then turning around and that's what you saw so you just got to keep going there
go the pillars um another closer
view actually like that shot as well because I didn't blow away the uh lights
in the lighthouse um don't know if anyone's living there or caretaking they
certainly don't care if I come out an image so you know I'm still with you
today um this is one of the uh best shots I took with the uh this was both a
photo photography type shot where I trained it and just being a night shot
um with the Aurora right in the center this is that shot was composed I did
some more work with it um and then there's me processing
looking around there's a lot of red if you open up the exposure all the red
light just sort of shows up you have to there's some stuff you can do to see
there I fixed it so that it wasn't so red so this uh solstice night it was a beautiful night
and took a lot of images but fortunately it all came to an end if someone would
want to buy one of your images for a print or something like that how how would they go about that well they could
talk to me and show tell me which image you are interested in um I use local
Printing and can ship um I know I can ship to anywhere in the United States I
will have to find out if they will ship all over the world to ship to other
countries but um I will my email address is ATV Sigma
gmail.com um and um W I generally work oneon-one
with folks to say if you're interested in an image let me know how large you want the print to be and how you know if
you want it want me to have it framed or if you'll frame it we'll work together and we'll come up with a fair price
Adrian why you put uh in chat your email address and I'll post it I will and I'd
be happy to yep and we'll finish this so daylight came and so did some birds I
didn't have my birding lens and I will definitely put yeah
they there's a couple of there's a couple of shots that are worth showing Now flip through um I will put that in
chat and you know what let's see if I can click out of here let's just do this
okay um roll all the way down I took a lot of images and the image this is the final
image I'll show everybody Sunrise um put the camera on a twig near
the shoreline and took this photo another photographer's photo uh dep of
field with the sun rising in the background and the um the little icicles I think you know I think they're back
out there now because it snowed today but um that is um I had I was there for
maybe six or seven hours yeah and um enjoyed Imaging at the for the winter
solstice it was a beautiful um sto to take a look around
to make sure you know just to enjoy what I was seeing the Aurora never shows up as brilliantly as you photographed it
from that far out um once you take the photos you see all the colors that are
actually there your sensor picks it up but you can see movement in the Aurora the light the um you know the excited
plasma that's going on up there um and uh and again Milky Way
Photography I'm I'm an avid Chaser now so I have to yeah as soon as it gets clear again I'm
gonna try and go back out there all right Adrian um make sure that you put in uh your email address or a website uh
where people can go and look at these you're you got some people interested
so let's see that so I put that website that's the website I was showing you um
okay button I can yep so Yep this is the website and it's fairly simple this is
what you'll you know what I will quickly sh I don't want to take all the time but
I will quickly share so this is my website that I was um showing this these
are the images I've got up there I'll leave everyone to uh click to it David
Levy who was here loved that image of that uh tree I've got a bunch of pictures of it uh University of Michigan
where I graduated and then on further down these are early images there's Comet and I do Wild Life
photography as well for for fun but I think most most of you most of you
watching right now are going to be interested in these images the night
photography the spring solstice here's some earlier Milky Way shots other Dusk
and night Dusk and nightcap and even dabbling in astrophotography actual
shots of images um uh deep space objects in the night
sky and the comet was including the comet there's other be space objects I
put there so yep Wonder there you go and thank you thanks Adrian no problem
wonderful okay so we have uh cesara and Molly here who who who would like to go
first um I gotta get off at some point to go eat dinner so okay all right so you're getting hungry all
right have the thing ready we not
yet awesome okay um so excuse me here we have Messier 65 and
66 so uh two of the three members of the Leo Trio I can't quite fit all three in
the field of view of my C8 but I'm working on an image uh that took on my
refractor um recently um that uh it's looking good so far but I want to apply
some new techniques to it before I put it out um but uh this is a live view of
M65 and m66 through my 8 inch M Cass grain there and I'm taking three minute
exposures just through my my light pollution filter um the the're
relatively close to the Moon right now so there's a lot of extra light pollution in the image there but the uh
the one on the left is uh 65 and the one on the right is 66 my images is flipped
um so they're both about 35 million Lighty years away in in like the Leo I
think it's called the Leo one group of galaxies and they're actually both of the same type they're both an
intermediate spiral galaxy but they're at slightly different angles with each other with respect to us so they kind of
look different to us from here here and they're they're kind of close to each other physically um something like uh
200,000 Lighty years separate them which is I think about twice uh no less than
twice the distance uh from here to the melonic clouds but um there there's
there's not a whole lot of star formation going on in both these galaxies so they're not gravitationally
interacting a whole lot they did in their past it looks like from some of the weird warped shapes shapes of the
two but um yeah a lot of heavy star formation is usually a sign that that a
galaxy has been disrupted by usually another galaxy and you know that there's
a lot of star formation when there's a lot of of uh hydrogen regions so those galaxies that have lots of pink and red
clouds all throughout them and um in uh Broadband pictures of them and stuff
like that are ones that have recently interacted with other galaxies and and
are having lots of star formation going on as a result of that um so this is a a
live stack I'm taking three minute subframes and let's see I've got I had
to restart the stack um so I've only got nine minutes total integrated time here
but you can kind of see their shapes yeah that that low integration time um
and yeah they make a nice pair and are are really cool to look at in the the telescope to because they're quite
bright along with the third member that somehow Messier left out of his list
even though I think it's about I don't know there's some galaxies I've been I've been looking at Imaging
lately that I I just don't know how messy I missed these you know yeah I was reading though that there was a comet
going through the area at about the time that he was trying to catalog things that were not comets and suggestion that
maybe he missed um missed the third one because he was paying more attention to
this Comet um but I'm not sure I don't know that's just what I quickly saw when I was uh looking up some some
interesting information on these Gala there's a little question here uh Herold lock is asking by interaction do you
mean consumed by other galaxies not necessarily uh that that is one way that
interaction can happen but um think about um like if you hold think about a
a balloon that you've rubbed on the carpet and and charged up with with
electricity you only have to hold it near your arm in order to get the arm hairs to stand up they don't actually
have to touch and it's quite similar with galaxies um they only have to pass near each other as they're moving
through space in order to start pulling material Across The Emptiness of space
and that movement of material can often times spawn rapid star formation because
you're you're mixing things up you're adding some energy to the system and um that can cause the star formation so
they only have to pass near each other they don't even have to um consume each other or even directly pass through each
other although like the wh poool Galaxy for instance is is interacting with uh NGC 5951 or whatever it is a little one
next to the world Poole Galaxy they've actually passed through each other a few times in the past um but these ones have
probably just passed by each other sometime in the last several hundred million years very cool very cool
all right Molly thank you yeah and uh enjoy your dinner yeah I'm gonna log off
and and go eat it's nine o'clock 9 almost 9:30 here I Wasing online tutorial with someone so
all right Molly thanks again for coming on that was wonderful absolutely good night all all right Caesar you are up
next yeah yes Scot I I have really
really near to have R the stacking of the of the picture
okay well we can we can share my screen to suffer together
okay here you can see the the the end you can see the my screen now it's okay
yep okay okay well you're you're you're watching the the end of
stacking and I think that uh I'll have the the final image maybe I think we're
just seeing the dialogue box of the stacking I don't know yeah the stacking dialogue box and the and the maybe you
are okay yes the problem is that you you are only no problem I can search I I can
change this to this share screen again and
here because there are two different uh um windows I see yes now is is where you
okay we will set we will watch in few seconds I yes the final the final
image Computing final pictures median and yes again we need to see
what is what we have in the
cook um this time I uh do you remember the last time I showed you pictures
separate pictures with a part of the buing wherea Karina nebula was was in
the back of the was blocking the ne NGC uh third
3 three five6 I think I think that is is the number of this and general nucle J
uh GNC uh Catal well now we are waiting for
to have the the final stacking stacked picture I took uh around 50
50 lights I used the dark master dark and a a vas dark a
bias master or Master bias uh I don't have flats for this objective
unfortunately um but maybe we will have a medium
quality uh picture from the city from the balcony
and sorry that it's this is all real time and we are we are waiting this yeah
that's the way it is yeah yes few seconds it is yes you can see
the bar called live yeah
yes and this time I'll I'll first of all I take the the cubes
here with the same program and we reopen with Photoshop only to see a bigger a
bigger uh picture of more completely in in a in
a full size screen and and two we can take with the
better quality the cubes the the luminance but here we start to talk we
to touch uh luminance and and
saturation but I need that this software finish
the picture of course well 3 C 30 20 seconds 19 17 come
on yeah it's like a countdown to the launch absolutely yes like a SpaceX Dro
is tomorrow or how how is the the loue oh I I'm not sure I'm not sure I'm
a I'm a little I'm a little out of sink right now with SpaceX yes maybe one or
two days I don't remember uhhuh I think that the the crew is is going to the to
the capsula um but I don't know when is
this I was really happy to see the Ingenuity uh uh you know drone uh fly on
Mars that was really amazing come on you see that
mindblowing yes mind blowing yeah because it's so historic because it's
not a a um it's not propos proposed by
by only um Rockets if not is using the air
of another planet right well here we have there's at
Karina here we have something interesting first off all we can make
the saturation in 18 is okay ah see I clear the
building yes it cleared the building yes I started to take the pictures or site
the pictures when the building put off of the screen of of the of
the of the field was off of the field
luminance maybe a little more is it a mosaic or uh one one frame so sorry 50
frames I understand you okay or or or you ask ask me another thing sometimes I
don't understand all completely in English what I mean by a mosaic Caesar is that you have like multiple adjacent
fields of you that you're tiling together yeah I okay yes the field is
around you know maybe three or four degrees because it's a oh yeah this is
one single shine wow was is an ed80 or what what is
the what St this is the stack the
stack um what are the Optics St 50 yes the
firstr they are a composition of uh uh 50 50 lights of 15 second seconds and
what what is the focal length the focal length is around uh is originally
is um 400 MM but with the by the crop
sensor because we are using a b ABS CS H is around 600
mm I see I think that this it's
around I an idea of I don't remember now but
it's five degrees it's around five degrees that's a good feel though yeah
nice beautiful Caesar thank you ah it's a pleasure thank you that's great
nice to see southern hemisphere objects like this so a
nebula a nebula is a very great nebula let me see if I can see no the best keep
them coming Cesar this is great we love the southern hemisphere
yes yes is if you have an opportunity to go well you tell us that I I think that
I I listen you that you you went to the sou
ere or it's a goal of mine to get some of my own images of the Southern
Hemisphere Stars I'm not sure how we're going to pull that off but maybe if I'm
patient in a couple of years I'll finally get to go so I I enjoy seeing
that it's a preview of some things that I'll try
when I get down there yeah yeah closest I came to the southern hemisphere was uh
was the uh Singapore Singapore just uh just right on the equator but uh I never
got a chance to do any observing it was just too too light polluted right
Singapore is very light polluted that's true last Friday Pedro my friend Pedro
saai describe it like a big dome like a real life uh
planetarium because in the in the night the thing is that you have the center of
the Micky way in the Senate um of course that I I know from Atlanta
Georgia the sky in in in united in the north hemisphere is amazing too um but
something that many people that came from the north hemisphere ER told us
that the the sensation to have the in the Senate the center of the Milky Way
that is really bright really really uh um looks like solid
like something that you can touch is is amazing it's it's something different
and sometimes we forget this but in in winter when your summer ER when we have
the the Milky Way you know we have a Capricorn Sagittarius and and Scorpio in
over your head and this is a huge a huge area of full of star um is um it's
amazing we we have uh one of of our places where we make the S party in in
in Mendoza near to the Andes to the mountains um it's a very clear sky very
very ah thank you that I had I I don't stop to share the yes uh it's amazing
that um we turn off the lights because when the people you know um um after the
dinner the people go to prepare the telescope and we use an amount of light
because it's a it's a sport center uh field and have lights and we turn off
the lights like a and in this is amazing
because sometimes you need maybe 15 minutes to see the stars there in Mendo in SF is so bright
this the sky not so bright it's dark really but the milway is so bright that
the sensation is that you turn off the lights and it's like a turn on the
projection of of uh planetarian wow this
is a people from the ABS well I I I told this to to Scott when we received
the the abso spring meeting in the
2010 uh we make together with a really amazing meeting with Aron Scott and I
don't remember the names well of a lot of people from the ABS from Boston um
was an amazing contion of people from Argentina and United States UK uh came
people from Brazil Chile and um really uh we enjoyed that um that sensation of
to share the the hemisphere uh souer sky
with where people say wow yes and um really is it's something
that um it's amazing well I I am for me
for I ever I'm helpful helpful for the
uh to the people from atana sonomy club that they invite me in the
1999 uh to there star party in in pach state
star Gaz in M near atana Georgia um was
a a wonderful I have I never feel
so strong Hospitality for the people and something that is is incredible that all
people that went that you uh found in another sari in another place of the
world make the same Jes uh talking the same Jes the same humor the same sense
of of uh Soul or Hospitality you know it it's amazing
it's something that is is like now Cesar don't re too much we are
coming from Sweden to your secret hunting [Laughter]
lands yeah well peka how are you today I'm
fine I'm um I was shooting the
moon almost until it uh uh Drive uh pass uh western western uh
uh area where I have my house facade so I took a movie when it flew by oh cool
it it disappears behind the wall so I was shooting uh I have processed now all
my almost four of them I can show you then please please if you want to do you
see them right now or sure okay let's let's go on
[Music] business can start with
the today Sun maybe
okay no it was yesterday or yeah
yesterday [Music] see it ah okay see some sunspots yeah MH
it's with ed80 and 178
mm there something on the limb there near the limb there's
three different spot groups uh this is the new
one and there is uh I think uh I have to
check with numbers this is but uh I uh I will go get my u p Continuum
green filter today okay and with
UV uh IR block filter it will be much
more detailed right so right now I'm shooting only with the white light
filter but let's see some
moon start this is only processed very fastly for this show so I I haven't done
any any work very
nice let's see where we are okay
it's this one of them should I uh let's see if I can move this one
yeah can expand it a little bit so you can see little bit
detailed on it it's going so slow in your in your
uh very nice
nice yeah I got it quite sharp actually this
uh Aus mon Aus it coming soon for you it's it's a
delay about 15 seconds from my screen it looks beautiful it's beautiful
nice and it's only 88 80 mm wow and when I take when I take my e
pass 652 nomers filter with my Ed
120 I can expect the little bit
more very nice and then we
have this one very close up for craters and don't ask
name not yet have a funny story about observing
the moon uh once I was at Palomar Mountain where the his Palomar 200 in
telescope is behind the 200 in is the 60 in uh that was I guess put up by the
Oscar Meyer family that makes Oscar Meyer Foods or something anyways um the San Diego astronomy
Association was there and they had turned the telescope onto the moon and
you could see that the eyepiece was not on a diagonal but pointed straight out the back of the
telescope uh now normally of course they don't put eyepieces on uh such
telescopes but they did for this observing night and uh everybody wanted
to see deep Sky objects through this five foot diameter uh mirror but they did have the moon and
you could see the image of the Moon projected on the floor I mean it was so
bright it was so bright so and so they asked who who would like
to see the moon and all of these other amateur astronomers they said oh no no I
don't want to I don't want to ruin my night vision I said get out of my way I want to see the moon through a 60 in
telescope yeah peka I will tell you that the image the scene conditions were so
still that night yeah that it looked like you could see gentle Rolling Hills
on the moon like mine yesterday last night oh my God and then we got to craters and it was just so much detail
and everything it was mindblowing it was incredible I was the only one in the group of I don't know 30 amateur
astronomers that actually saw it uh because everybody else thought it would like ruin their night vision for the
night I was I was so pleased I I just you know after that observation of the
moon I I was completely satiated I was just like this is great I'm happy you
know uh you know I I if that's all I could see that night I was I was pleased
but of course it didn't take so long for me to regain my night vision to look at other deep Sky I can show you my night
uh how how condition was I can show you some movie clips okay but Scott I have
done that I have looked once full moon through my 8 in geston ah with the 32 mm
I think yeah okay and you know I will never do that again no no because it it
was so bright it is pretty bright and it hurts it hurt your eye
yes I got it was I will never do that without a
filter wa out of solar filter yeah no yeah almost let's see if it's my picture
is yeah you might want a neutral density filter can you see that we have a thousand of
pictures yeah it looks like we're Vanishing off into Infinity is that because me or let's see
I I sh can I yes I stopped
sharing we're back should I show you some move it quickly so you can see the
conditions okay how how how good condition it is it
was let's see I will move this
uh somewhere else so I can see you as
well there
see there and
share oh come on share and
there there we go oh that looks familiar
peka I I uh I encounter those conditions regularly now in this picture there is
do you see those very thin clouds yes yep but they will disappear very soon
after that is like uh I was like in in in the you
know so that was a really really good night yeah very still MH can
so that was that that that is one m I was looking to see if you were
Imaging it looks like you imaged it before lunar X and lunar V would show
up what's lunar so though there are features on the moon there's a couple of uh
bordering craters if the uh Terminator the Shadows hit them just right near the
uh southern part of the Moon it looks like a little X on the moon and if the
uh near the top near theare it looks like a little bitty V on
the move and it's just it's just a feature of how the Shadows hit the moon
as gross I haven't had time to check them yet because uh I shoot them for six
hours ago well you're you're shooting you're shooting a little bit better than that
you're you're going in and seeing actual craters I mean you're you're digging a lot deeper um I would say that these
images are more impressive than you can handheld you can handhold a camera with
a large lens and get lucky enough to take a picture um but like you can
see some of the ridges in your picture right now if you look kind of to the lower left what happens is sometimes the
shadows will hit those ridges just so that it would appear to form
those letters but um it it's a novelty for those who take pictures of the Moon
using uh you know using our cameras um but I'd say what you're doing
is far more impressive okay thank you thank you very nice this last one is
when the moon is going it's coming soon for you there it's
going right behind the wall cool well there we go
bye and Fade to Black yes yeah and good night for
me very cool there you are thank you thank you thank you
yeah okay well gentlemen is there anything else to share or do we call
to okay let's do it uh if I can share the
screen oops sorry was that you Jason you f oh hey Cesar okay so um let me uh
share the screen here okay so the moon we were just on the
moon let see
okay okay so I just got the Moon it just went off a little here oh yeah so can
you see my screen yes so I want to do a little Moon cruising with you guys
soing Moon Moon cruising cruising the moon so this is just uh this is with my
um 13 millimet langler so it's like 156 power with cell phone with a cell phone
with a so it's in an 8 inch I know you don't like eight inches looking at the
moon but this is the way to do it Pekka yeah you know your eyes you don't have to worry about
your eyes you can look at now here's the cool part though watch watch what when I zoom in this is what an 8 inch this is
what an 8 inch can do for you right yeah if I it's shaking around because
I'm let me just let me just let it stabilize wait let me just go a little bit to the left yeah mine was 80 mm I
have 12 left and then my 8 inch and then my 11
inch so you can see quite a bit of detail and and if I it's really nice to be able to
see it uh if I go wow the mountain peaks there yeah now
it's a little you can see a little bit of seeing but let me just focus a little bit more o sorry sorry for the jigglin
here there we go that's that's that's pretty crisp and then you can see you
can see all the little ridges inside of the Mari oh yeah and you can see
the impressed really you go a little bit Yeah
impressive and you go this way hold on sorry there we go W see all the little
cradle crater LS but and you can see I love I love when you see on the right you can see
some of the uh Peaks coming through uh just just peeking out and getting there Sun I think it's awesome
unbelievable and then just uh go in here I think one of those features you just
looked at uh Cameron formed the lunar v um it was a little
further you know Cameron your your your
uh 8 inch is so well cated that I'm a little bit
jealous well I all right so let's uh let's have some fun with this view before we go let's go to the Apollo 11
Landing site is that fully visible yet let's take a look here yeah it's over
here to the left it Apollo 11 is
visible but it's uh it's on somewhere around here e forgot exactly little
further south I think it's actually if you go yeah I think you go a little further
south zoom out a little bit Yeah okay zoom out some I I'll I'll look at yeah
you guys tell me where to go all right let's zoom out a little more all right so let's see the
okay okay yeah you were the backwards view so so I do believe
Apollo 11 if you go a little further south it's
actually it's actually down yeah now it's in the if you zoom in you're
zooming in towards where Apollo 11 landed now you it's so that's the mar
and to the right somewhere is where Apollo 11 actually
landed yeah it's to the right of what you're showing excellent you can see that some of the crater lets
there yeah and so in this
area if I am not mistaken of course course um one of the planes in this area
is where they landed um Apollo 11 Apollo 16 is not too far away from the Apollo
11 it's a little it's even further to the right and a little and a little bit
above where you are but um Apollo 11 and Apollo 16 landed SE
Tranquility um to the left and then Apollo 17
landed North on the Northern edge of the Sea of Tranquility so you would have to
zoom out let's see if we can find that we zoom out and
then we go north a little bit same sea
but in this in the area so if you go if you go left
of where you are now um let's see y if can go that way and
then we drop go up a little further yeah it the northern the upper part of your
picture um is the area where Apollo 17 would have
landed and yeah actually there's a really yep you
good oops sorry let me just get this that's okay yeah go ahead and zoom in we
we'd have to we'd have to look up some of the crater names I know there there's some names there we could look up and
then finally Apollo yeah Apollo 15 is the other I
think this well that'd be a lot of that would be kind of dangerous for
17 to land there I'm not so sure that was the actual site I know it was North probably a little south of that area um
South and well it's East you've got a reverse view of the moon but um kind of
where there's a v leading into the Sea of Tranquility um I believe that was
Apollo 17's landing spot uh
15 now 15 there's 15's a little e e to spot this
Ridge if we go if you go north so you move north down to the
center this was the all Michigan crew of Apollo 15 they landed in a small Ridge
next to the Sea so so this mountain chain so if you go north and I guess
left so if you go up in left of where you're looking there's this hu okay so
that's the wrong direction let's go to the other Yep this that that area right here is the Apollo 15 Landing site
that's drifting South and off of your screen that we just passed by the Apollo
15 Landing site so now it's no it's at the top of your screen there's a little
plane in between these two ridges and I'll have to double check
because it's either it's that little area where Apollo 15 would have landed there's also this um area here and but I
believe they actually fit Apollo 15 down here so um so those were four of the six
Landing sites are visible and if you count Apollo 13 that would be seven
because Apollo 14 landed where Apollo 13 could not land because of the
complications they had so 12 and 14 are on the other side facing of the Moon uh
South quite a bit way south of the crater cernus which I think is the large
crater that right now it's not visible it's it's in Shadow uh when the moon becomes more full you're able to see the
other two Apollo Landing sites and uh there were six total
um I am I am always okay to be correct Ed if I rick Hill's not here some of the
other lunar experts we have aren't here to correct me
um if you if those but I know that the landing sites are close and you can see
why those are not Landing sites uh those were not pick there are obvious reasons
um you do not want to land you know where is going to be easy to crash and
that part of the move moon and the whole moon is Pock marked but those Seas
provide enough flat ground to uh to land to land and um I know that the um I
don't know where the uh Chinese Landing spots are um I know one I believe is on
the far side so we would never be able to see it um naked eye from Earth and
they they managed to land on the far side and did some exploration there but
um yeah Cameron these are some these are some beautiful moon images kind of proving what kind of detail you can get
with a well columnated small aperture scope and an iPhone mounted to the
eyepiece or or however you've got it mounted
um but uh yeah and most important most important
good seeing I I just lucked out I mean this is pretty darn good seeing tonight
I have to say Adrian uh do you know what angle size uh
was for Moon Landers that they could not
exceed to reject from the Moon
surface um I do not know that um I know
that none of the missions aside from 13 because of a problem
none of the missions aborted Apollo 11 almost missed their Landing site they
were coming down on Boulders and so Neil Armstrong took control of the Lander
manually and moved to the site where they eventually would touch down so that
manual adjustment yeah but I mean don't know what the angle of Entry was no
no not the angle of Entry when they land
the The Landing site so the when the M Lander lands it can land on the surface
that is on two uh how do you say on angle I I think
it's only three or four degrees that is that is something that I
think I'm going to be looking up yeah they they could only so they cannot be
te too much they can't land on yeah if the ridge is like this that's
that no no but they can not shoot they cannot re it anymore because they have
to it it must be almost flat flat and level yeah I I'm
sure there's a yeah which is why your
Seas area was a better place to land than anything over to the right I think
Eagle was three degrees tilted uh and that was uh really almost
maximum yeah um and plus with the with the adjustment that uh Armstrong had to
make I imagine it was it was a little bit of a gamble actually yeah because
I I haven't seen anywhere the actual maximum Ang
angle or the Tilt when they are able to land on that spot where they are going
to land because afterwards when they land and it's tilting too
much they will yeah not be I imagine it you know if you talk totally level at
zero it can't be very far from that at
all um that's an interesting that's an interesting point and something to look
up because I'm sure that play factor in I have a lot of project but there is
some questions I I haven't get haven't been able to yeah
yeah and I don't know if I don't know if well targeted Google searches will direct me to Publications but uh I still
think that's a very good question um I know that other the moonlanding since
have had to take that into account as well whether manned or unmanned um all
the the unman moon landings I'm sure had to make sure they were um they were
landing at a correct site yeah this is yeah but the te on
69 yeah on my watch in my Samsung watch I could land on Mars
almost yeah and see I think well we'd have to look at because they landed perseverance on Mars right and they I
think they had to pick they picked the crater I think uh yeah the zero crater
if I'm not mistaken on Mars and they had to make sure the landing
site you know wasn't very well tilted either um a lot of exploration that they
had to do and I want to say that the crater they picked on Mars is similar to the feature that we're seeing on the
moon right now on Cameron's screen um not the uh I don't know if it would be like this crater here
um but uh yeah you're hitting a small with something like this you're hitting a small Target from you know from you
you your calculations better be spoton um that NASA team
landed um perseverance I I don't I don't think they missed if they missed they
didn't miss by much at all where they landed it so that that level of prision it's interesting I'm reading an article
here and um uh when they did land they they were off by several miles of of the
the place that they had chosen uh and it said there's some worry inside NASA about whether from Earth
they'd be able to pinpoint the lunar modules Landing location the moon was
mapped but not in anything like fine up close detail there were no
constellations of tracking satellites around the moon in 1969 with a rise smile Armstrong radi o
Houston he said the guys who said we did we wouldn't know where we are are the
winners today in the 22 and a half hours uh Armstrong and Aldren were on the moon
in the eagle NASA never found them the crew mate Michael Collins was overhead
orbiting the moon in the Command Module col Columbia The Command Module had a telescope as part of its navigation
instruments and Mission Control asked Collins to search for the lunar module and his crewm mates for every time he
flew over it was a bit of like a wild request even with the telescope Collins
was orbiting at 69 miles looking down on his on his space bigger than Manhattan
trying to find a spaceship that looking down from above was just 31 ft across
with himself traveling at 3,700 mph according to account had just two
minutes search the in area during each overflight so they they never actually
found him in the and during the time know where they are then not exactly oh
my God yeah exactly I'll tell you what they ended up alive because of uh Armstrong's
maneuver I uh think the alternative would have been uh a little
more catastrophic than that very true 29 seconds left of fuel
yeah it's something that you can imagine it's incredible yeah a gutsy but heroic
car yeah oh that that documentaries has been
watched so many times and every time have you seen this uh very slow motion
or original video from uh Saturn 5 launch of the engines
I have it on the launch pad that's something I'll need to uh
look at as well um it's it's not it's it's it's an original video and
it's the one camera filming in high very high speed the highest speed at that
time and you can see how the iron and the uh first of all all the all
painting works just float away it's like
powder and you can see how the actually the iron begins to
burn when the four five engin started and uh you can feel the power of
them actually that is that's very interesting yeah when it
when the uh moon is out it itself is an interesting topic you know Scott you
mentioned that um a lot of astronomers the amateur astronomers they avoid the
want to ruin their night vision with the moon right but I A A lot more I would
say a lot more amate astronomers those that are still watching when the moon is
out um take a look at it and uh you know
see what you can find because um reflected sunlight it's not it's not like you're looking at the sun or
anything so right it it can be bright and the bigger the aperture it can your
eye will suffer a little bit if you don't use a Moon filter and the moon is
full but um yeah the the moon gets a I think you
learn you know who's come into astronomy amateur
astronomy or or who the mentors for some amateur astronomers are depending on how
they um view the moon I remember with the hardcore visual astronomers the moon
was pretty much the enemy and um and you're almost taught to hate the
mooners the deep and yeah and you know visual observers it's about it's about
these faint fuzzies and that's that's where excitement comes from so there's
nothing wrong with that view but I I found it less stressful to go ahead and
take a look at the Moon itself and see what I could learn I get the email from uh Rick hill now and um it's fascinating
some of the uh you know all of the craters that he observes and then he shares with us yeah each of those
creators is named and if I was was able to Rattle off the names of those craters
like I can rattle off the names of stars you know that would be it'd be fairly
impressive trivial knowledge because you can always look these things up right but it's uh it would still be fun and
impressive I only know of um look how Majestic a couple of them look how Majestic that is that's beautiful it is
it's mesmerizing yeah I'm just uh I'm really happy to be able to share this I mean this is the first I've seen it like
this um and uh I have to say this is a wonderful way to uh to look at the Moon
without burning your eyes out yeah exactly I would just if you remember the
settings you put I mean I think a lot of these are standard I see you're using Pro mode um yeah let me tell you yeah
thanks Adrian just for just for everyone's benefit so I'm using a a Samsung Note uh note and there's three
different cameras when you put in Pro Mod it uses the middle camera okay so that way when you line it up with the eyepiece it doesn't flip around that's
what was happening earlier um changing changing camera so what happens is you do that it forces it to the one camera
and then uh and then I'm uh it limits the the zoom to 10 times uh so I'm at 10
times right now uh the native uh one times this is my eyepiece uh resolution
which is 156 power um but when I go 10 times I mean I'm really impressed that
it keeps the the Integrity quite nice and the pro settings I use are um I use
for for Focus I focus to infinity and then I go and then I go
160th of the second uh 160th a second and I I you can play with the iso like
uh that will make it sharper less noisy you can play with that so you you you
can do different things um yeah you know obviously that's your game right so so I
I change it to more and then you can change the uh
the exposure time obviously but uh I think you know you can you can like go lower exposure time but with this seeing
uh we are really really good so the the 160th of the second seems to be pretty
Optimum and then if I change it back to 100 so yeah this seems to be a pretty good pretty good setting yeah but
another thing you notice as I'm as I'm doing the cruising here um you can see it's shaking around a lot and and and
it's there's not much wind but this shows you the mount right I mean I I don't forget I'm multiplying by 10 right
on top of the uh the the power I think that's atmospheric
disturbance you're you're basically going through the at you're going through the atmosphere and it's like you're underwater a bit um not much do
that that wavering it's true but when whatever I touch and I'm playing like you can see when I'm like doing doing this type of thing and then you see it
takes a while to there's some vibrations like right now then it starts settling that's just the mount right and and then
I I have to go my taxi is coming I am going to good morning good morning yeah
I have to leave some PL samples to my doctor but uh if I can share my last
picture I I just got it ready here do it you bet awesome let me
stop sharing it's the last one before go
go nice nice beautiful yeah it's hard to take the the
picture this this is really good really good thank you nice and
it's great work it's and that's with an 80 millimeter too that's an 80 millimeter awesome yeah yeah yeah so uh
when I got going on with my uh 8 8 in and 11 in with AC you know what you
might want to try peka do you are you using are you using a Barlo or a a power
m not not yet not yet not yet you should try you should try uh try that and
increase the fing that that will that will help yeah I'm trying to because I
have several cameras I have several uh telescope so I have to find the optimal
combination combo sure yes so it's it's
quite uh it's not so easy to find the right combination actually yes but you
figured out your your your your setup I mean you you've got your Mount which is great and you can just switch the
optical tube right which is great I love yeah I love the mountains it's as good as almost as uh
Scots uh this big one or the gm1 yeah yeah a
beauty yes but I'm I'm pleased with the ggx it it's it doing well excellent
excellent take thank you yeah thank you and have a nice upcoming day and sleep well and see
you tomorrow all right see youor good night good morning bye bye bye bye bye
thanks byebye I think that Caesar had one last one that we wanted to show yeah Southern
Skies gonna call it a night yes good call good
call finish the one more for the road one more for the road this is the the
the last is that the Jew box is that the jewelbox cluster yes yes
yes here do you have a cluster this this
the Mimosa star for the Southern
Cross you know the more you you you CH us the St this is this is great I mean
uh we'll be all ready to go when as soon as we get access to the southern Skies it'll be really fun yes here do you have
the the the oh it's the coack yes the co yes oh yeah yeah you can see it this
area no because do you have you have this area yeah actually yeah I see there's a
string too and the coock has a little bit of dark NE velocity that kind of goes into the chain up up up there too
yeah yeah yeah in this area you have you can see the the
[Music] the this and um today I first I started
with this is it the entire sou crass well
this is yes I wasn't not so good uh I need to
to re uh reprocess again and I I will show you the next week for the entire
next week and the C sack and
this is just thear neula oh
yeah nice looks nice beautiful not so good but yes is very interesting for for
a only a camera you know this this is very interesting
because this this shape is part of the explosion of the star in Tarina oh
that's cool yes yes that's that's called the butterfly nebula is that right H but
not in this area uh yeah khole nebula is the name of hehle hehle nebula yeah
yeah yes and when you zoom in the Hubble the Hubble image of that right um sciss
there the Hubble image shows it like you say there's kind of like a a darken band in the middle and it kind of explodes in
two directions like like an hourglass is it right um yes The Hourglass yes yes
The Hourglass yeah exactly right yes yes that and and is in the middle of the
city this is a polluted area but amazing it's amazing the middle bueras oh that's
great it's great lights and you know it's um but it was a great was a
great experiment from here to with a only a camera reflex camera with a a a
suum of 300 mm Us with a cop sensor
of 60 the 40 40 sorry 40 mm focal
length um well it was was an amazing no not amazing was was a nice a
nice uh uh to to take a picture tonight
yeah thank you very nice you guys thank you very much for your contributions
tonight sharing and camaraderie and all of that so uh until uh the next Global
star party which should be next Tuesday um we will uh we'll you know we'll see
you later and uh and to the audience thank you for all your great comments
and everything and yep as my as my great
friend Jack kimer used to say keep looking up and we'll see you uh next
