Global Star Party 105

Transcript for Part A:

foreign
hey Chuck hey Chuck there you go hello it's been a while
yes good to see you good to see you Devin I'm really sorry about Wendy
um I appreciate you I I learned about that on a trip uh only too late uh is
there a memorial fund or uh yeah if you'd like to donate something in her memory I would the
Linda Hall library of science ah excellent is being recommended as a um
as a place to donate that's fantastic that's a wonderful
selection but I'm terribly sorry about it uh thank you
I really miss her it's a big it's a big lonely house right now yeah
okay
but there's one thing that works only one and that is when I go out and observe
and uh it's like taking an enormous tranquilizer without any side effects at
all I feel so much better when I go out observing and I think Wendy would have
wanted that
I think many people experience uh tranquility and comfort
when they do stargazing you know absolutely
you know I think it's just uh it's not often that I meet someone
that's indifferent to it but occasionally I do you know occasionally I do I I'm I'm stunned when
I see somebody that's a little indifferent to looking at an amazing Sky you know so
Connor Bradley is watching on Facebook says is there anything out in the universe that is like a tornado similar
to a tornado well in a Christian disk around their
black hole might be a good candidate certainly it would be very
very massive and we have storms on Jupiter uh many uh yes tornadic storms
yeah they're Vortex like phenomena and
several scales and of course even the in the formation of a galaxy or a solar
system uh the angular momentum produces a tremendous amount of rotation you know
that lasts for very very very long periods of course either things rotating
in a star system or uh this is something that's not well understood even yet how
the spiral shapes in galaxies last for billions of years right that's a tremendous amount of
angular momentum that is not in a sense like a giant tornado but in in a sense
it's a similar uh movement
yeah it seems to be a uh a natural kind of movement throughout nature
I also think that one of the Vikings recorded a tonatic like event on Mars
once foreign and of course Martian dust devils are
very frequent and they're sort of like micro tornadoes if you will yeah
we have a little treat in a uh video it's a sonification and also a uh
a short video maybe you guys saw this but it was a meteor uh meteorite that impacted Mars uh on
December 24th so something almost about 40 feet in
diameter made a magnitude 4 earthquake that both Rovers
uh you know recorded
so it's amazing I mean the you know getting uh up to the minute uh
goings on on another planet another world you know like that
we live in a pretty good time to be interested in this kind of stuff oh man yeah that's right
that's right and Chuck you were on like a trip across
the country right yeah 5100 miles worth of driving goodness I I had a lot of
stops to make along the way visiting people and uh and then uh
business to conduct in San Diego and then back across through Texas and stuff South Dakota is not the fastest way to
get from Louisville to San Diego I've discovered but uh-huh it works a friend
of mine uh paramotored into 72 000 volt lines
um lost both hands oh yeah nasty it was burned over 23 of his body good Lord oh
spent nine weeks in a burn center in Denver man oh man
it's crazy
foreign
so we have someone that's joining us new but they had to pre-record his uh talk
was uh vachik uh kacha truck uh you met him uh David eicher when we
were at starmus yeah and so he's joining Global star party and giving a talk about uh space shop 42
and you know uh what they do and the Outreach that they do and
you know very unique uh little organization there in Armenia so
yeah Connor Bradley then then you get those who oh then you get those who believe
there is a Multiverse uh would you get those who believe there is a
Multiverse would that totally change the world of science
um yeah if a Multiverse could be proved you know first off there's a Nobel in it I guess for someone which I heard again
and again and again at starmus if you could prove that Scott you could get your Nobel so I mean it's it's
mathematically plausible of course but but the as far as we know those there
are people working on various ideas about how maybe you could infer the existence of other universes
observationally from within our universe but of course on first second third
fourth and fifth blush the fact that you're in this universe yeah the
conventional singing is you will never have evidence of other universes if they do exist yeah it's like being in a vault
and and trying to infer are there other vaults outside of your Vault you know right but you know we don't know
absolutely but but that's where the conventional thinking is at least at the moment but we don't we you know when we
know really well the character of about 5 percent of the mass energy in the universe were a long way from saying
that we understand everything already oh yeah
a hell of a long way you know way way far far some detection would be
theoretically possible if there had been a collision at some point in the Deep past there was a cold spot detected in
the cosmic microwave Background by the Planck satellite and by its predecessors that was
uh suspicious for that but no confirmation of course
um and many of the inflation Theory
generally regards the beginning of the universes rising from a Quantum fluctuation and it's hard for physics to
come up with any scenario in which there would only be one of those so uh that's about as far as it's gone
yep David just before we start have you do you have a copy of John meacham's new
book on Lincoln I do not I heard him this morning on Morning Joe talking about it I don't
have a copy of it yet I'll have to grab it and he's a fantastic historian and
I've read his books on Andrew Jackson than on a few other people he's about as
good as it gets as an American Lawrence O'Donnell and yes that was
really interesting yeah he's terrific and and you know I think the best historian in in Tennessee if you will
you know academic historian and one of the best in the country so but I had don't have my hands on a copy of it yet
I always remember so fondly the time that you and your dad watched the movie
Lincoln yeah with Wendy and me yeah that was really some kind of an evening wasn't it and that's a such a
spectacularly historically accurate film of course it's a wonderful film yeah but
the best part we're seeing it with you and your dad and that was a tremendous time and and now the two of us are here
and and we miss John and Wendy yeah yeah yeah
okay guys we're gonna get started uh thanks to all of you that are
watching out there in the audience uh this is the 105th Global Star Party windows on the universe
the perseverance Rover is filling up tubes just like this with Rocky material from Mars and it's my job to protect
them what kind of testing are we doing now to make sure that they survive their Journey back to Earth let's take a look
[Music] at the base of a nearly 90-foot drop
tower here at NASA's jet propulsion laboratory places like this are designed to help test out NASA's most ambitious
campaign to date tomorrow's sample returns I'm Raquel Villanueva here with Aaron
Yazzie he's in charge of keeping the sample tube safe on their journey home so Aaron what's the plan from our sample
Richard Mar sample return is the next leg in us being able to bring back Rocky
samples from Mars to Earth so that we can study them here and look for signs of ancient life what kind of testing is
being done here at JPL to prepare the sample tubes for their Journey back to Earth the sample tubes have already gone
through a lot of testing to date but we're going to continue testing to make sure that they can survive every leg of
this Mission some of them involve mimicking Mars environment practice robotic handling of the tubes making
sure that they can survive each of those steps the launch environment The Landing environment
speaking of final descent back to Earth that's what the engineers are working on behind us can you tell us a little bit
more about those tests the tower behind me is actually able to mimic the event from when the canister holding the
sample tubes will land back on Earth one of the designs that we're currently testing out is what kind of crushable
material we want we might want to use inside of that assembly so this right here is actually a piece of titanium
crushable that we're going to use with this Mass simulator to see how best to
cradle and protect these tubes when they land back on Earth what is being done to ensure that this is a successful camp
okay we are currently partnering with agencies across the U.S and around the
world the most predominant one being the European Space Agency we're actually working on building a hundred more test
tubes that we can distribute to all these teams so they can do all their testing and and ensure that everything
will work like they designed it to what are you most excited about when it comes to our sample return I am really excited
about all the information that these Little Rock samples hold inside them especially the exciting probability that
we could find ancient life for me personally I come from an area in
the U.S that looks like Mars the Navajo Nation is a rocky desert landscape and
it really reminds me uh how similar rocky planets in our solar system can be
it's a very cool perspective to bring with you thank you for your time Erin thank you and NASA is sending your name
to Mars so if you'd like to get a boarding pass like Aaron has right here please follow the link below and to keep
up with the latest updates follow at NASA JPL and at NASA Mars or take a
deeper dive on the mission websites at mars.nasa.gov [Music]
hello everybody this is Scott Roberts from explore scientific in the explore Alliance and this is the 105th Global
star party we have a great lineup of speakers uh as usual including someone
all the way from Armenia uh who's joining us via pre-recorded uh he had to
pre-record his talk because the time that we'd have him on it would be 3 A.M there so he really was
he's a working man a working engineer but uh he was with us at starmus and so
it'll be uh it'll be great to bring that on but uh we uh like every Global star
party uh bring on David Levy to start our program with some poetry and some
words to capture the moment here so David um you've got the stage
well thank you Scott it's great to um it is wonderful to be here and wonderful to
see all of you to see some of you anyway but anyway
I'd like to begin by announcing the appearance of my new book my latest book
it's either my 39th or my 40th I can't really remember which but this is it this is it
it is called Clipper Cosmos and children finding the Eureka moment
foreign Rosenthal including this cover
illustration the idea for this book really began when I was 10 years old
and I wrote a book on my mom's old Smith Corona typewriter about our beagle
clipper and I did it put it put it away but
somehow I've kept it I never lost it and one day I was in my
one day I was in my uh in this room here and I noticed Wendy was reading
the original clipper and I said what are you doing and she said I didn't know that you wrote a book
about your beagle when you were 10 years old you have to redo this as an astronomy
book for children and that's what I did it took about three years to do it's not a thick book it's
um it's only about 115 Pages or so and it's about a group of children who
have a magic beagle name Clipper plus a magic telescope named Eureka and there
is a real there was a real Clipper there is a real Eureka telescope it is the um
you don't even have a picture of it here um yeah here it is
right here um this is an explore scientific
explore scientific um 12-inch telescope which is right now my
favorite telescope and I use it quite often a picture of Wendy on the right
is with my original telescope the very first telescope which
is now being housed at the Lindo Hall library of science
anyway the book is available we're going to be doing some book signings
eventually but for now it'll eventually be available on Amazon
but for now if you don't want to wait for that you can get one directly from the
publisher it is Ron W Kramer let me um
yes it's sorry Ron J Kramer Ron J Kramer
k-r-a-m-e-r one word gmail.com uh of course I think uh twenty dollars a
book and this is meant for children to be able to um enjoy it to be able to
go out and look at the night sky and it goes into the solar system Stars
galaxies and there even is a chapter written for the children about the great
voids in space it's kind of interesting to try to sell the kids on a whole chapter about
absolutely nothing but I had a lot of fun doing this the book came out
excuse me the book came out in September release
September Wendy was able to see it she wasn't she was too weak to read it by
then but she was able to see it and I gave her her copy and she studied the
front and the back covers of it examined them and wasn't able to read the inside of it
by then anyway the book is available and I really I really really hope that a
lot of you can get it to get Inspire the Next Generation and the one after that and the one after that to to explore and
enjoy the night sky for my quotation today we are having a theme called
windows on the universe and there are a lot of Windows there's
the one at the back here uh that I can look outside and see stars but there is a real window that one can
see if you look in the constellation of Sagittarius it was discovered by Walter Botta
and uh so to quote for my poem to this week I'm going to quote from John Keys's
on first looking into Chapman's homework with a couple of changes made
much have I traveled in the Realms of gold and many goodly stars and clusters seen
around all the celestial Islands have I been with eyepiece on telescope to the
night sky hold off to one wide expanse that I've been told the Galileo ruled as his domain
yet did I never breathe as pure Serene till I heard bada speak out loud and
bold and filter I like some water of the Skies when a new planet swims into his
King through his Majestic window looks upon the Milky Way he stared at the
center of our galaxy like a diamond shining in the sky with a wild surmise
silent Through The Mists of space and time thank you and back to you oh that's
beautiful that's beautiful thank you David thank you okay all right
um I like the little variations that you do so it's nice it's nice okay all right so
um uh we are heading out to our next speaker here uh uh and this will be
if I've got it right I think it's Chuck Allen Chuck are you uh are you available I'm
available I'm right here they're available right well I'd like to I I always uh uh like to add some Fanfare to
um um the uh astronomical League they are
I think uh probably one of the best groups in the world for joining for
getting involved in amateur astronomy um you know they have I think it's 80
something like 80 observing programs they are constantly
putting together uh events they participate in live programming like
this one you know they often travel to their member organizations across the
country they are they have expanded around the world with their membership at large program and they have thousands
and thousands and thousands of members um uh you know it's an uh largely all
volunteer group in fact it may be all volunteer at this time uh and um it's
been going on for over 75 years and so the astronomical league is certainly
something where worth joining no matter which club you belong to if you already belong to a league club you know where
all the members or League members then you should participate in their programs more than perhaps you already have
um and uh you know I think it's uh it's wonderful that they do come on to a
global Star Party explore scientific is honored to be an
underwriter of some of their Awards um you know one of them is the national young
astronomers award this is where you know I really got to meet Chuck Allen for the first time he was I think he'd already
developed this award and so it was really great to see it in its infancy
and um it has been really uh wonderful as well to see the recipients of the
national young astronomers award go on to do amazing things in their life you know I mean it's uh you know I think
that getting recognition uh for for something you've worked hard at is very
important and uh the league puts puts that on a kind of a high mantle you know
and it's it's something that uh you know when when you see these young people receiving these Awards uh you know it's
a huge moment in their lives and it's a big moment for all of us as well so uh
when when we're there so I'm going to encourage you to go to the next astronomical League mention uh
which will be in Louisiana um and um you know we're we're a little ways
away right now but they're already starting to promote it so but uh I'm going to turn this over to Chuck uh
Chuck has uh if you have watched him uh you know put on his astronomical League
hat on uh you might have also seen him give talks about you know the biggest
the largest the you know the furthest uh you know the most amazing
um things in our universe which often leave me with a my jaw just kind of hanging open
you know so Chuck I'm going to turn it over to you thank you so much for coming on oh thank you Scott and uh for those
of you who aren't aware of it the reason the national young astronomer award program is in its 31st year now is
largely because of Scott and his uh support and sponsorship of the program
with telescope prizes and uh transportation for our winners and so
much more and we really are deeply indebted to Scott for that it's really brought a lot of exciting what an honor
hugely important to us um I'll go ahead and share a screen and get started on our door prize questions
for tonight I think this will be the one
okay one moment
okay we usually like to begin because we understand there are a lot of people who
are new to astronomy who may join us on these very widely observed gsps and that
is a solar safety you can observe the sun safely but it has to be done a
certain way and it has to be done with the use of professionally made solar filters that include energy rejection
filters at the front end of the telescope that prevent most of the sun's life from entering the telescope to
begin with you don't want to use a solar filter that attaches to an eyepiece or
some welders glass or other smoked film filter that you think has cut down
enough light because it may be letting harmful infrared light into your eye you don't ever want to leave a telescope
or binoculars unattended in daytime where a child might aim it at the Sun if you're using eclipse glasses bear in
mind they're only for use just you and the glasses no binoculars
and no telescope I think Scott did a demonstration of what happens when solar
glasses are eclipse glasses are exposed to the light coming out of the telescope where the sun is uh has been acquired it
just melts the film so they're not for use with Optical equipment and they should be certified and safe as well so
if you're going to be observing the sun with a telescope or a new telescope you buy please contact somebody of a local
astronomy club and we can provide that information to you through the league or
find someone who's skilled in solar observing who can help you do it safely these are the answers from the GSP on
October 25th presented by Terry Mann the first was what two planets did the
moon occult in October of this year and the answer to that was Uranus on October
11th and 12th in Mercury on October 24th the second question was on a moonless
night under Dark Skies in Jupiter actually cast a shadow and the answer is yes it can't so can
Venus and the third was what was the name of the first comet discovered and we
accidentally left off the words by telescope so the answer we were looking for was the great Comet of 1680 which
was the first one discovered by a telescope but since we left the words by telescope off we'll accept older answers
as many of you probably know comets were observed in the sky and recorded as
early as like 465 BC and a comet Comet
Hallie even appears on the Bayou tapestry so certainly there have been older observations so we'll accept older
ones for this one uh the questions for tonight and please make sure you send your answers to the
email at the bottom of the screen secretary at astroleague.org
and the first question is does the Sagittarius A star
about how far away is it is it 2 600 light years away 25 600 light years away
2.6 million light years away we're 56 million light years away
the second question what astronaut went to the vicinity of the Moon twice
twice without Landing
and the third question for tonight hailed as the largest combined after
telescope in the world on the Wikipedia list this telescope can be found where
so then Arizona South Africa Hawaii or California
it has two 8.4 meter mirrors combined images
and that will do it for the questions for tonight Scott thank you very much there Chuck
all right um we are going to uh
come back to talk about uh meteorites I had mentioned kind of Backstage uh you
know our microphones were hot before we start our regular programming uh but uh
we have I'm going to show you some video later of the impact of a meteorite on
Mars and uh the sound of the impact of a meteorite on Mars but uh David icker uh
took us through all the minerals well not all the minerals and crystals on planet Earth because there's a lot of
them but he took us through a lot but now he's uh he's going on to meteorites
and this is meteorite's part two with David eicher
thank you Scott and if you can remember far far back in your youth all the way
back to August I spoke about part one about meteorites that was before starmus and before our
big break with doing this it's almost farther back than I can remember at my
age myself but I did talk about meteorites part one which were about Stone meteorite Stony meteorites tonight
I'm going to talk about the rest of them and so I will see if I can share my screen and then I will see if I can
share the correct thing on my screen and then I will see if I can start the slideshow and can you see a slice of a
media right yes you can we're moving in the right direction then this is going to be Stony irons tonight
and iron meteorites and a couple of really weird types that are unusual that
I'll talk about as well but this is a slice just to get us going here of one of the beautiful so-called Palisades
which we'll talk about eskel which is a nice uh specimen from the Bob Hague
collection let's review all this business for a moment about meteorites to understand
what we're talking about in 1492 a stone fell from the sky in what's now Ms shine
France but centuries passed after that witnessed fall before Skeptics came to
believe that Stones could fall from outer space it was a very unusual concept back when nobody really even
understood what those lights in the sky were the fall of stones at ligle which
is a French word that means Eagle in Normandy in 1803 that was witnessed by
many people and 3 000 meteorites fell in that in that event and that converted a
lot of Skeptics at that time early in the 19th century but in the United States of America it was a few years
later in Connecticut there were three loud blooms occurred and a tremendous
shower of stones cascaded down uh in over a town mostly over a town called
Weston that really convinced people in the United States in its burgeoning era
of science if you will and and Academia in the United States that this business
uh could not be denied any further and there was an important uh professor at Yale University nearby Benjamin Silliman
uh after whom by the way a mineral silamonite is named collected specimens
of this fall and analyzed them and it was really clear what was happening then in America
right now there are more than 40 000 meteorite Falls or fines in their broadly classified as Stony Stony Iron
and iron the three broad types of meteorites they're mostly pieces of
asteroids meteorites are and the most exotic or even lunar there there are
more than 370 lunar meteorites now known in more than 175 Martian meteorites
known as well and we'll talk about a couple of examples of each of those well what's this business if you can
remember all the way back to August I you may remember me talking about some of this how are meteorites classified
because of course in science is the first thing that we do before we understand what we're talking about at
all is to try to classify things whether they be bones or rocks or what have you
so the three primary classes of meteorites are Stony and within that
class which accounts for most meteorites by the way and those are either chondrites which have chondrules grains
of melted and re-solidified droplets of early material material from the early
solar system these are not modified by melting or differentiation and then
they're the more unusual achondrites which don't have chondrials those are
differentiated and reprocessed and are more similar to some kinds of Earth rocks
the rare and unusual and beautiful often made into jewelry or into display pieces
Stony Iron meteorites uh it wasn't really understood where those were formed or how they they were where they
came from for a long long time this unusual class but they really represent
boundary material now between the mantles and the cores of asteroids they
consist nearly of equal parts of meteoric iron and silicates and usually
forced to write as it's now called it used to be called more commonly Olivine the mineral and Jewelers uh even it's a
beautiful sort of yellow green Gemmy material often and Jewelers often cut it
into what they call Peridot which is the an August birthstone it's magnesium
silicate and Olivine crystals it's believed now in these asteroids uh form
in in a sort of a sinking toward the core and raft in a region near the core
of an asteroid there that is iron and nickel rich and that's how you get these unusual combinations of palestites that
have both iron and also big Olivine crystals within them
somewhat common although a small much smaller number of course than the stones or iron meteorites those come from the
cores of asteroids mostly and those are metallic they're iron and nickel Lake
consist of roughly 90 percent iron about seven percent nickel and a small
percentage of other uh unusual and metallic elements as well these are cool
and they're easy to get and they're often inexpensive and they're nice to display however a warning to collectors
of meteorites uh what exists abundantly in our atmosphere here that keeps us
alive but oxygen and oxygen of course likes to combine with things like combined with things like iron
so uh iron meteorites are fine but you have to realize that the outset that
there's regular maintenance uh and we can talk about that at another time if you want but what it amounts to is every
few years essentially you have to bake them in an oven and then you have to coat them with a varnish coating of
exactly the right type and that will really slow down and off and almost stop
the oxidation which will stop your meteorite from becoming a pile of rust
and then they are very very uh rare kinds of meteorites that we'll quickly talk about tonight as I mentioned the
lunars and the Martians so after all of that I just thought I
would present a few examples of some of these mostly irons tonight this is a a
meteorite fall that is very well known especially to our good pal David because
it happened relatively close to where he is there this is Canyon Diablo and if
you've ever been to meteor crater in Arizona uh this is the fall that produced the crater
most of the iron material that uh that came down and pancaked and and exploded
and created the crater which is a large crater it's the best preserved meteor
crater on Earth um was vaporized and is gone and and to the horror of uh uh Mr Behringer who who
tried to go down into the base of the crater and mine uh valuable iron and
nickel um more than a hundred years ago but his grandson is still around and owns the crater now and so thankfully you can go
and visit that and see it very nicely with a great museum there as well it's
an iron octahedrite from Coconino County there it was found in 1891 it fell about
50 000 years ago which is uh an interesting uh association with another
well-known crater in America which I'll mention here as well ah it's next forgive me this is from
eons ago August here so Odessa the Odessa media Creator in Texas which you
may have seen by the way if you're driving Westward toward the Texas Star Party you may very well at some point
have encountered the Odessa meteor crater this is another iron octahedride
and it's it's very similar in character to uh meteor crater and there's a good
reason for that it's believed that the same object um splintered and created both craters
meteor crater in Arizona and Odessa in Texas
this is not easy to see here it's a sort of a mirror-like finish if you have the
meteorite right in front of you and angle it just right but this is something that you can do with uh
well-maintained uh iron meteorites this is chinga from Russia and you can polish
them to a very high Sheen and almost have a real Cosmic mirror if you want to
here this is a very well-known Russian fall from just after the turn of the
20th century and reasonably plentiful here as well and very very dense so some
of the irons are so dense and stable that if you take good care of them you can make them you know into fun things
like you know mirrors or belt buckles or Rings or watches or what have you
this is another one that's often used for because it's very easy to cut here
gibeon and it shows very clearly here in this little piece that's a few
centimeters across a characteristic kind of pattern in the iron that that is
shows up in most iron meteorites the so-called vidmenstotten pattern which is
very unique this crystallization pattern in meteorites you know native iron on
Earth is fairly rare specimens but they exist
um but usually iron was combining with lots of other things on earth early on but with meteorites you see this
crystallization pattern and this comes this very unique uh kind of cross hatch
pattern in meteoritic Iron resulted because it's slow it cools uh
very very very slowly over millions of years and that creates this Oddball
crystallization here's another very plentiful iron
meteorite here that is one of the most common cicada lean from Russia also it
fell in 1947 a huge amount of it was recovered in a region primorsky cray
that's also very very well known for lots of kinds of interesting minerals too and here you have really in many
cicotta lean specimens this is really common with these these regma glyphs
that are that are less dense areas of the meteorite specimen uh that were
etched away as the as the iron passed through and heated very very briefly
through Earth's atmosphere often tumbling as well
here's another very very common one this is a little tiny one but there are zillions of these out and about Campo
del Cielo another iron nickel meteorite this one from Argentina this fell long
ago 500 years ago almost and uh I'm sorry was found and then it fell about 5
000 years ago but a huge amount of this was recovered so there's an enormous amount if you go and get you know a five
dollar iron meteorite at the Tucson gem show you know uh which you know kids can
collect handfuls of this stuff it's often Campo because this stuff is so plentiful
this is another slightly more unusual one this kind of looks like a turkey leg or something like that this little piece
Mundra Billa which is an Australian iron a fall it was found in 1911 and fell
prehistorically at some unknown time and it has some unusual inclusions of
different minerals in it but again most all these iron meteorites are very similar chemically
here's another one that allegedly and it's not proven completely but allegedly
was a meteorite that fell in the high desert in Chile down near where some of our favorite telescopes are now Vaca
muerta which means dead cow and and the allegation is that it hit a cow this
meteorite and killed it when it came in but I'm not sure how absolute that is
and then we get into some of the palisites this is braheen from Belarus
which is a very plentiful and pretty common Palestine and here you can see that there's this Matrix of iron and
nickel uh and along with the iron and nickel are these uh beautiful Olivine or
or forsterite crystals so often you know cutting these into jewelry or big
display pieces like this or backlighting them with a light and letting the light shine through the Olivine which close
nicely in a sort of a yellow green uh color is very nice again you have to be
a little careful with these because over time the iron will Rust but the
maintenance is not bad with things like this this is admire and this is kind of an
ugly little specimen but this has a favorite place in my heart if you will because the first time I met Walter
Scott Houston who was a hero of mine and helped me out with this early publication deep Sky monthly and
contributed toward it even though he was a sky and tell devout writer for many
years first time I met him on a trip that was to go to stellophane where a
famous friend of mine was also there with me David Levy by the way this year
um Walter Scott Houston gave me this meteorite and and so it really was a
special thing this this specimen for me and David I don't know if you remember this but we actually spent one night at
stellophane that first year when it rained like there was no tomorrow and we
had to go down you and I if I'm remembering this correctly and break into my parents room who were staying at
the heart in his house rather than camping like you and I were and we slept on the floor the iker's
room at the heart in his house you remember that oh I do that was quite something but
um while you're talking about the gibian I wanted to show that I actually have a
specimen of Gideon right here nice as a wedding ring wow and uh so I show it
from time to time I've lost so much weight since Wendy's passing that I've had to put things on because otherwise
the ring falls off my finger I'm not careful with it well how special that is
David wow that that is really something and a real treasure to have with you it
really really is reminding me of oh that's amazing Dave thank you for
sharing that now we get to that's that s scale which
I think is uh maybe the most or among the most beautiful of the palisites and and it really shines here this is a
piece that uh Bob Hague had he in fact he had the whole entire main mass of
Escala as he did many other significant meteorites and and uh what a guy and
what a what a sort of a genius uh um you know uh just celebrant of
meteorites and and almost what's the word he was almost like a you know had
an Evangelical spirit for spreading the joy of meteorites he's still around in
Tucson by the way he's sort of the dean of meteorite dealers uh Bob Hague
and then there are a few other strange things that are actually these are impactites now Libyan Desert glass this
is uh sand this this is you know uh silicon dioxide from Earth it's not
meteoritic stuff but there's clear uh evidence that this was fused together
into Libyan Desert glass this piece and countless Millions like it uh in the
Libyan Desert by the impact of a meteorite about 29 million years ago so
impactites that are Earth's stuff that have been impacted and changed
fundamentally by meteorite strikes also exist here's another one that's very
plentiful stuff from the region of bohemia the Czech Republic
now and this is moldavite and it's sort of very dark green but very lustrous uh
volcanic glass it looks like it's a tectite that was an impact strike from
the very large crater that uh passes through the Czech Republic and also Germany now this is about 14 and a half
million years ago the nordlinger Reese crater
and this is an interesting and odd thing and I mentioned uh earlier when we were
warming up Ray shabinski when Rey and Michael bakach and I were out at Tucson last year uh from Anne black and other
great meteorite dealer we got these specimens a few of these this is an impact diet called a Sue avite this
block that's cut out of it and this is also from the nordlingeries crater impact about 14 and a half million years
ago this is from nordlingen Germany and what's cool here
is it's both an impact diet a meteoritic artifact and they also took this stone
that was impacted then and they built the famous Church in the City Saint
George's Church out of the impact Stone and then this was taken out of the
church so it's an artifact both of the impact of the meteorite and of the
historic church when it comes to putting on your historian hat from noidlingen
Germany um so it's it's you know both uh meteoritic and historic in nature as an
artifact and uh very strange stuff there and I thought I would finish with a couple of
examples my couple of examples of lunar and Martian meteorites because they're
the most exotic types of course and they're very rare and and you can see you know for a few hundred dollars you
can get a lunar meteorite or you can I've seen them actually marked at the Tucson show you know up to you know nine
hundred thousand dollars you know for you know so they're rare but you can get
a tiny piece of one relatively affordably this is a piece of the
largest uh lunar meteorite on Earth and of course you could ask well how do we know it's lunar well we know it from
comparison of uh isotopes of oxygen in the Apollo samples which were brought
back um and they're identical to a small number of stones as I mentioned that
fell on Earth this is Daryl ghani 400 which is a piece of the largest lunar meteorite it's an achondrite of course
and you can see the differentiation in it and so this is this is basalt um and
the impact age here this is something younger than 3 million years ago there
was an impact on the moon
it fell here in the Libyan Desert and and you can tell the timing on these
things because of a very complex set of chemical analyzes in the recrystallization ages of certain
elements in them so there's a piece of the Moon you can hold in your hand and this thing that
looks like a chunk of sidewalk concrete is a martian meteorite this also I got from Bob Hague and when bakic and I went
over to Bob's house this was a decade or more ago now you know Bob hey you have
to know what a character he is David I'm sure you know him well he opens the door and he throws this thing at me and he
goes hey Dave here catch and it's the main mass of zagami the most valuable
rock on Earth the largest Martian meteorite on Earth and I caught it
thankfully but handed it back to him and he sliced about a third of this meteorite and paid for his house
in Tucson and he has about two-thirds of it still in his possession in his house there
um and it's uh from zagami Nigeria um it's a chunk of a piece of the
largest chunk of Mars on Earth it's about 180 million years old and it
traveled before it landed in Nigeria for just a little less than three million years so it doesn't look uh incredibly
sexy as meteorites go but this is the rarest meteorite certainly in my collection
and that does it for me uh I will be happy to to take any questions if you'd
like or do that later and I will stop sharing now but Scott that completes I
think my at least for now dance through minerals and meteorites and I may here
in a week or two if it's okay with the chief Scott turn back to some real
astronomy it's all astronomy you know and all right
yeah it's all connected so you know that's why they call it the universe right yeah
excellent uh it looks like Mr David Levy has his hand raised here uh
um I just wanted to uh ask if you knew the name of the scientist who discovered
the connection between the nordligan meteorite and the church
oh I don't no and maybe it was Gene Shoemaker
now that you he was his father had just died
and he and his wife Carolyn were in Germany they went to North Lincoln
and um they went to the church first thing
and uh he took one look at the church and he said that's a meteorite
the church is without that meteorite wow that's wild and that's
that was Gene's second big meteorite Discovery the first being the uh
meteorite nature of the Arizona meteorite absolutely and when it comes
to meet impact science you might ask what did she Gene Shoemaker not discover
Maybe yeah well that's that's really really true
but um you know as we got on later as years go
on we kind of will start losing people that really mean a lot to us we have lost
both Jane and Carolyn and Wendy and people who have
really contributed a lot to what we know about science and so it means that the
generation that follows ours now needs to really get on their bicycles get in their cars
and really start to make their own contributions absolutely I got in my car the other day
to go get my images two nights ago so I'm trying to do my part to feed and uh
David your description of the uh
billion dollar meteorite being thrown at you to catch um you reminded me of a skit that um
Dave Chappelle did where he claims to have found the last remaining dinosaur egg a T-Rex hatches out of the egg and
what does he do chop his head off so that he could cook it and have food this
is a waste almost like a waste of a what would have been an incredible Discovery so it's it gave me a chuckle because I'm
like yeah he's he could live off of that meteorite he in generations and he just
throws it to you like it's a common Rock so I I applaud you for making that catch
because that's that was a very important catch um so uh very good and and you all
are convincing me that I need to bring and make more money so I can join you all at starmus that looked like a good
time you will have a riot at starmus Adrian I I can promise you that and and thank you
for those comments which are fantastic and you have to know I mean Bob you know we love I'm saying this in a good way
Bob is a little crazy you know to do stuff like that you know but it was a good thing that I caught it yeah a good
record good hand-eye coordination and recognition in your part so
okay okay well uh you know uh I posted a couple of
uh of sites one of them is Bob Bob hague's sites uh or his site uh if you
guys have uh a meteorite collection uh I also posted a link to how to preserve
your your meteorites you mentioned David how important this is um so they're you know they talk about
the varnishes and the techniques and all the rest of it so you can see that in the chat
um and as well as the Tucson mineral uh or the uh Gem Show
I'm sure you'll see that in the chat but before you before you coat them okay you
want to cook them too so that there are no water molecules nothing in there and
then you coat them and then they let them go for another five years or so just put it on low or something or if
you want it really cooked out fast you just put it up to like a thousand degrees or so honestly yeah I think if
I'm remembering correctly and I'd have to check now but it's something on this order I I think I remember cooking them
at 350 degrees wow you know for two hours so it's like making a fine souffle
you know cooking the water out of your meteorites maybe we can do a live you know live meteorite cooking show that's
right there's an idea for a show that would be exciting we're going to
slice carefully into this meteorized souffle right here so now
I'm going to my Dave Chappelle skit that it's the taste of Health gets coming
back no all right Scott we've officially gone off the rails yes we have but I I didn't
want to remind people they can buy you don't have to be a you know a wealthy person to have meteorites they are
they're rarer than diamonds uh they're they're incredible to look at and to own and to hold this is a very small
specimen uh that was uh given to me as like a gift but uh you know I've had
bigger ones and smaller ones I tend to give them all away so uh if you meet me
sometime maybe if I have a meeting right you're probably gonna get it so anyhow but um it's a lot of fun to have them
and fascinating to learn from so and Scott you're right I mean at the Tucson show or other you can get a nice Stone
meteorite for a few dollars and very nice specimen that's awesome yeah yeah
yep okay so uh as promised uh we are going to have uh vachik
let me see if I get the name last name right kacha shrian catchatrian from
space shop 42 in year of an Armenia and this is this is the hypocenter of where
the starmus event occurred uh David eicher and myself got to meet vachik uh
during uh this event when we first did the uh astrophotography school for
starmus and then later on uh he was with me uh during the time uh that the
starmus camp was underway and I was in a crowd of thousands and thousands of
people um uh with only one telescope but it was a lot of fun and um uh this is this is
vachik here and uh he's going to introduce himself he had to do it pre-recorded because it's quite early in
the morning in uh in Armenia right now so here we go
uh hello everyone my name is Paul chick I am happy to
participate to this event sorry to send the
recording it's too late in Armenia to participate online and thanks Scott
for inviting me so I'm a co-founder
of space shop let me share my screen with you
foreign I will present today uh it's the amateur
astronomy in Armenia the community I was developing going and how we as a
community support our supporting it so I made a short list about what our
company does so we are basically a specialized online
shop for telescope but we also do lots of other activities to to build the
community so we we are trying to educate uh people
and that's why we have a popular scientific blog in Armenian
um we we are and Consulting uh for telescopes for
everyone to buy from from us or from themselves to to become a part of the
community we organize Astro tools to let everyone to see the dark skies and Armenia and
also to observe the Deep Sky objects we promote telescope making and we try to to to
sell uh the telescopes that that amateur
makes amateur people make and we we also meet organized meetups with general
public and and students and kids to
introduce introduce them what what is a mature astronomy and also the promotional science and make some
interest in them from from young age so this is the way that we build the
community in in Armenia so let's dive deep into the each each
point separately so this is a general view of
our website we basically you mostly have telescopes
but also we we saw some accessories with them and
also uh different scientific toys books
and so on let me show the website
for you so you can see the escorts 10 inch explore scientific telescope here
so the eyepieces so
um you can see here
uh overall website so accessories and toys
so on decides
uh okay doesn't go through full screen
um besides uh the product part we also have the log
log part that where we write in Armenian for uh for everyone to
understand like we try to write very general to not use very specific words
and try to explain um not only the working of the
telescopes that I present here but also um trying to write
uh trying to write in um different things like the
space junk about uh a rock around
a rocketry and many many interesting uh
arrests of science to engage kids into this
and we also do consultancy for the
telescopes as I mentioned so um we organize
like people contact with us and ask different questions about the telescopes and usually they don't the uh didn't
even see first time with the scope so we organized some Meetup to for them to
come to see with different telescopes to understand what telescope shows which way and what
you can see and not see how to choose your first scope from what to start if
they are interested in seeing or seeing or astral Photography in general
and um uh yeah we
also organized austral tours so what did uh what what it is it's uh
um We Gather We Gather people we take Transportation go to the dark spots in
Armenia like uh 40 50 kilometers
from the from the main city here everyone the sky is very dark and you
can see the dark sky and deep Sky
objects so and one of the in one of the events we
went this year we went to see uh meteor showers with some campfires uh talk
about science talk about astrophotography with them so it's like
enjoying the nature and also um and and
also talk Talking uh with each other to uh to to build build
the community of of amateur uh astronomers
uh yeah talking about the telescope making
uh this is one of our guys
um Grandpa's uh his name is followed yeah he's uh 92 years old now on his uh
he started to make telescope when he was 88 years old so these are his telescopes
he's building all the mechanics and also the Optics uh he's grinding the mirror
polishing it he made specific equipment for that so
to promote what he does we put his
telescopes in our website trying to sell it to give him additional opportunity to
continue this work also try to
uh connect young people with him to transfer the knowledge and and the
interest to continue amateur telescope making in Armenia
I think they said um and we do Outreach events a lot we love to
[Music] um uh meet with kids and talk to them we
organize lots of events during these two years
like going uh different places in Armenia not only in uh Capital City here
around uh as Armenia is is not so big so we can just drive uh different locations
and um with the help of the local communities they organize to the public to come and
to to listen our talks about science about education and about amateur
astronomy and the uh usually during after the talks we organize stargazing
events so we watch uh usually planets and show them what
what they really have the dark sky in their communities
this is a rest from our recent event
the solar eclipse that was visible in in Armenia so we organized the public event
and we made some sunglasses
a special for to to look to the eclipse
uh this is one of the events in order that we went uh to talk about the
science but it was a big science scientific conference
uh this is a it was space one of the events that we
organized one week Space Camp uh for for the kids
um and we are also did some stargazing
event and also public talks with them foreign
Festival that we did with uh with explore
scientific team and and many many other supporters
we had a great uh
stargazing event in Kearney one of the uh ancient temples in Armenia it is uh
fourth Century actually so the whole event
went there and many many many people came
like Jim barley on here the first Armenian uh astronaut
and like many famous people so also during
this almost starmus Festival we visit to Smart Center which is located in glory
in Armenia um for them we also organized the
stargazing event and also one one of our successful
events was the science as science camp
which was in the center of Iran Opera square and
um where um where we showed
talk about ourselves show our products and telescope and also we did uh
stargazing event there and lots of lots of people and kids
participated in the event so I'm so excited about it and
so doing so much uh
things here we managed to peel the
local community of of amateur astronomers and actually this is the
picture of all uh the guys that help us to organize the
the governing event during the star most festival and all of them were operating
telescopes that dobsonian telescopes they learned to operate them before the event
and did a great job to to show the public
and so how we communicate how we how we
um continue development our community is by
using social media platform like telegram chats and Facebook so they can
ask their questions to the new new
um a mature astronomers can ask their question to more professional worms and
so they can communicate with each other and help each other to build the
community so we usually every um everyone who purchases telescopes or
has a telescope we add them to our groups so so the network can grow
and talking about our business we our
business is full online full remote uh we we don't have a showroom and so
usually we show our telescopes in our house or or
um uh or some other public places
yeah and what uh and about
people who are behind the behind all of this is our team that also work fully
remote and are from different locations of Armenia all of all of the
team members are young and the enthusiastic about what they do and most
of them have said has scientific background so this is a kind of me and my brother
and amelana who's started the
um the business two years ago and uh other guys are from like physics
faculty or this this uh girl uh is like
17 years old working remote from bartanese region which is like 180
kilometers from a far from Yerevan and uh as well as
um other
also 17 years old working
working from territory of Georgia she's Armenian and so
so we are kind of multi-location
and and like a 21st century business working
for remote from from our laptops uh
yeah so uh this is it that I wanted to share with you and if you have any
questions or if you want to connect with me um
I am this is my email that you can can connect and visit the
information about uh about our shop so a little bit Easter egg about
my title everyone in the team has a specific title like the CEO has a
spacecraft Commander type title and and
other team members like our Pilots or uh
over it uh pilots and stuff
so uh and one final note uh y42 in our
name special 42 it is maybe some of you will know the famous
book of two plus Adam's Hitchhiker's Guide to the Galaxy so the 42 is kind of
the ultimate answer to the life universe and everything and we try to uh
try to find the Ultimate answers of knowledge shopping and everything in our
vendor thank you very much
bye okay all right well thank you very much
Patrick um I assume that you'll watch the global Star Party when you wake up in your
morning um we are uh now going to turn this over
to Cesar brolo and Cesar are you are you bringing your son on to the program
tonight
Cesars had a little bit of trouble with his internet tonight here so let's see
uh there he's back
there you go there you go yeah we got you
okay okay I I try because I am outside my balcony and I try to connect my cell
phone to to speak uh my computer for this yes one minute
there we go
it's a pretty slow connection all the way from South America
yeah the network glitch is stopping him in Texas and it's preventing him from yeah there we go oh it's a live view
live view of the Moon yes yes very bad
excellent
okay okay
can you see can you see the Moon Scott come on yes I can yes
they can yes well
Scott I think we can hear the delay it was about three or four seconds before your response came through there
yeah I know but it's a good view of the Moon look it is a good view of the Moon
live from Buenos Aires
okay
well it's called I am sharing the screen yes uh
uh I am trying to to show you your audio is good now
uh okay okay perfect okay and we can see the screen
sharing okay okay yeah finally yeah right yeah the thing is uh
we built the the setup on top of a wooden deck which is very flimsy so
that's why we get all these vibrations yes
we are in the on the towers Garden oh I see
well there's a lot of uh a lot of detail on the craters here yeah we are actually getting a very nice
very nice detail uh perhaps you can describe the setup what what kind of scope uh camera
uh Richard Cartier 8 inches
[Music] to to X to tanks okay
and we are using around four matters Focus wow in a small camera right now in
a Sony it's a Sony sensor
297 it's a very small sensor it Times News only the match is going on these
these three craters are just like filling up the whole field of view it's amazing here's a very very very it's a
very very a small field of view
you're actually real near to where the uh breeders that form the lunar X are
we can move here because the the kind of floor as I I was thinking oh yeah the
floor is not real stable yeah yeah
but you're still getting it done you're still showing a live image to people all over the world
from Buenos Aires yeah so it's very cool
look at that Peak I love that peak of the shadow in the middle of that crater yes yeah right yes yeah
yeah that's very impressive it is we have a lot of seeing because it's
near to uh to a tower yeah all the heat yeah
yeah yes fortunately we have a lot of scene
for a city is I think we can maybe do a video and and get some
yes we can try later give you uh some image more more a decent picture of this
but you know the the possibilities of fly over the moon with a telescope yes
yes so if you're in your living room I suppose you can control the telescope
still right in outside and uh no today watch the uh
watch The View on your on your toilet absolutely we can go it's much further
but we can go uh outside this area and and
of course that we can we can uh Contour the telescope remotely
because it's only with another another computer to
to control this computer the screen and this is enough for
sort of make anything uh but as here is Springtime and today is a great night to
to be outside and you know it's not as told us some past days yes
today is actually warmer than than yesterday and before that we were getting some very cold and windy
days also this peak is is amazing
yes I think that we can we can get a a interesting picture of this
yes
well we can put a video
there we are see
very okay okay well
here here is the is the pool and we have a lot of light because it's
it's illuminated with leads and it's a nightmare but as we are
today we are making a planetary image it's okay
we are don't worry about I'm here you can see where is the moon this is
why we have a lot a lot of seeing because we have this welding
with the heat of the welding you know the the turbulence over this the image
is is really strong yes
but you know the Moon being what it is it's bright enough you can also see Jupiter
yes computer is here yes we can try but
um as we have we have a today we have a lot of problems to to make this to make
this setup um as we return from katamarca and I I
uh I lost the the piece the device for
the find there I don't know where I get I is is is the the
this way and uh yes you need a finder that's for sure yes yes I yes I don't
have a fine there and it's a little difficult with a lot with four meters uh
with four meters um how do you say uh four meters focal
length is a little complicated without finder um put the focus to a hobby there but
not impossible but maybe for a live image it will be uh for the passion of
the people of the audience it will be too much but we can try later
um with Passions [Music] because you know sometimes in your
telescope you can when you know your telescope maybe you can find some scripts that are in a line and you can
point something the problem is that I'm using a very small sensor with a viral
lens and it's not a reflex camera where you have a big sensor and you have the
opportunity to to point to the object more easily because they
now they feel that we have is you you know that it's like using a
1.5 millimeters Maybe in in their in this telescope and maybe
it will be very very complicated to to get a image [Music]
easy to to find quickly you know
right yeah sorry that that we start to go into the
roof and the the concerts have a problem with the kids
yes and say don't worry the keys and say my God okay well
um we return here where we have a field of view between the towers to see to
watch the the sky and watch hope it run the moon and well we lost a lot of time making
the setup again you know but well we have an image of the Moon are less right
yeah no I loved it I think it's beautiful you know I mean who doesn't
like the Moon sure absolutely Maxi sometimes say that that he he
missed the the very uh large focal telescopes
but remember that sometimes they are a nightmare yes
but you know it's it's something that all is it all is a challenge and this is
for us it's great because it's you know um if you use a very narrow field of
view you need to put a more adjustment but it's a real telescope it's something
that is great because because uh you you can feel the potential and the fragility
of the image in very long Focus yes yeah but occasionally the image sharpens
up and um uh it's still a delight to behold and it's very nice
yes absolutely Cesar do you remember the first time you saw the moon through a
telescope yes uh with uh my Telescope yes
we receive I received from the coating uh for from the culture or coaching
bathroom chamber my my mirror and I put
in the cell I prepared the all-day completely and I had uh uh half crescent
moon and for me was shocking because the the the details
so I can see in uh it was around
yes maybe three four four inches four inches uh mirror and for me was totally
I was totally amazed or afternoon maybe it was uh uh for me I was an
accomplishment to make your own Telescope yes yes yes because when you are maybe the entire year
grinding and polishing your mirror by hand of course and this time I don't
have the I don't have the rubber machines [Music]
actually is the best driver machine that I have is is totally functional
um but I remember completely completely all that we talk about the Moon is that
is the first thing that you can if you invite to your home
uh somebody to see by your telescope from your telescope
you have a moon you're a winner because for this
person it will be something like a c
you can believe that you know the the expression of not that the
people don't believe sometimes and today today in the time of the cell phones
social Nets that people say okay come on it's something magic and is is without
electronics um when you put the the eyes in the in
the eye the your eyes and the eyepiece and see the moon is the most
the most if impressive thing that you can see
through the telescope yeah later when you understand what are you watching is the same that I
told that week in in the skies of Captain America things where we we was
talking about you can see the Jorge the horse have been nebula can you imagine
or I saw oh I yes I saw the the horse in the limit yes yes because
the the most funny thing between people that observe from many many years
was something something like if I talk to another another people that they know
how absurd and they know maybe they they told me that I am crazy I say but the
most with them when I felt more confident and another another guy say
the same and say come on you so yes I think that I I saw the the whole the
horse had nebula yes it's not my imagination I was I was
is it was here the flame nebula was like a picture and Flame navel is not Orion
Nebula for the people that we are talking normally You Don't See flame nebula because uh first of all you
have a very bright stars very near to the flame nebula and in the same field
uh we are using expert scientific uh IPS of course in a in a
41 40 uh inches in six sorry 16 inches
Telescope yes um we we really enjoy a lot and now this
from the city the moon for people that that never watched by telescope the Moon
is the is the we know that the Moon is is the is the the queen of the night and it's
something that for the people say my God but if if you have your first side
uh if you're your first view by telescope with the moon you are going to
use more and more I understood a lot it's it's real it's real that's right
yeah that's right many people when I show them uh their first views through
any telescope uh I often show them the moon or Saturn or both you know and uh
they're just shocked that they can see so much detail and everything and it makes me think about Galileo when he
first saw these craters and mountains and stuff on the moon and uh had their
elevation that uh or Revelation that uh um you know the moon wasn't this
perfectly smooth sphere you know as it was thought you know so
um an amazing night that must have been for him you know
yes absolutely it's real it's absolutely uh well we are enjoying this we are
trying to point uh hoopita okay we are
um we will try to get uh a decent image to show you in the second section okay
all right that sounds good uh I guess at the at this point we will go on to uh yeah
but your internet's better right now so it's it's coming across pretty nice I I was still using for for the connection
connecting uh to talk the the cell phone and only for share the screen yeah
yes the computer but yes we are in an area an area where we have the the
condominium webs internet and it's also good like my home but we receive this
boat and maybe it's a mix and I use in the the telephone data that is much better
yeah yes excellent thank you so much all right
okay processing image and we are going to to
try with a hobby there in a few minutes okay all right thank you thank you very
much thank you so much thank you okay
so let's um there we are we're back um so uh it's been a little while since
we've had Maxie on our program uh uh but uh we're we're very pleased to uh bring
him back after I don't know it's been maybe three months something like that so uh but uh fabulous to have you back
on Maxie uh what's happening in your part of the world well hi again it's been a long time that
I've been here yes almost three months I think uh mid of August almost but well I've
been doing some stuff at final of August but then I've been you doing some
planetary in September and that's all in October I've been doing
almost nothing I tried to put the gear in a Pharma area from here but I was
very tired it was very cold I was I it was the night of my mother's
birthday so I know I now I say now those are all much more important yeah
so well uh I want to to show you what I've been doing this this time
let me share my screen sure okay so uh the 23rd of August I was
practicing a with M8 the Lego nebula with my eight inches and the cwo camera
and this is from my backyard this is only one single shot
but I want to uh show you the conversation between
this and in the Portal 2 slash three
area that was days before uh for example
now so this is one bad this is for example let me put it 100 percent and this
is 100 percent and if we compare
for the field of view rotates because I'll change the camera but you can see
there's a lot of a dark nebulas in the in better Skies than here
with borders six and seven and of course the colors and the shape
of the nebula is really really rough
here in my CD anyway uh I was in this case I was doing some practicing but the
the target of that night was two objects almost one but two in this case
because uh I want to do this place is that is in Corona
Australis that I love this area because I we have this
globular cluster but also this double stars and this newborn Stars
uh Crossing this near velocity and well this is a bright star and also
a little Galaxy right there so I've been doing almost two hours taking
pictures but I stuck the health because I been trying to get more precisely in
my processing so the final image that I got it was
oh sorry there was this one but now let me put it
uh what was the last one yeah I think this was
no well this is one of those you can see here there's an inverter
nine they say it has the shape of the nebulosity
and there's a lot of dust in this place that
surround this this place but this is a really good field of view
you know uh I think this place is a kind of planetary nebula I don't know but
some people told me that uh here's the
the Galaxy and well then I focus on the Galaxy NGC 300
I was taking pictures like almost four or five hours and this is a single shot
that I did and this tackle and processing image was
this this is the finally image
and you can see the core right there the arms of the Galaxy but also what we have
here there's a lot of Galaxy clusters you know I A friend told me that these two
British galaxies they are almost at a
2.1 billion light years so I can imagine these places they are really really far
away from here but anyway this galaxy belongs to the
the the nearby Milky Way
so this is the the the finally process image of this galaxy
and that's the finally what I did with
DSO pictures then I started I I put a
only one disk to get planetary captures uh because
the planetary processing is really really tough and I and you will need too much uh
gigabytes of data so I start with Saturn
in August I was practicing a at the first time with my monochrome
camera and the filters but I couldn't have the the the results that
I want so I
I went to the color camera the the the Deep Sky camera but I did planetary
images so using a Barlow 3x [Music]
um I was able to do this kind of Saturn
and in September I got
the most uh Saturn they're really they're really
good one Saturn um I think there was the final image
or one of those
and you can see the more details oh that looks nice Maxi yeah I was practicing a
lot I was talking with Nico and having regulator and they
support me too much to to get this kind of a planetary you know with the F4
telescope yeah it is very nice it is very nice
yeah so I I say okay that's that's all with this uh well I think this was the
better processing because it has better colors and the the lines of the of the
planets you know I was really shocked so the night of the 5th of September has
really really done almost done I pointed to the red planets
so I have to take pictures again to comparison and see the the how change in
the size yeah because in December isn't it uh opposition in December yeah it
will be much a little more uh is M big than this
but it will have a I hope that repeat the the shape that we had two years ago
yes so uh of course uh I been doing
Saturn Mars but also I was practicing with Jupiter
uh I also you can see there's a lot of files that have been taking pictures and
also videos but
this is a animation that I did
of Jupiter and you can see it was almost one one and a half hour
you can see the rotation and
I don't know it was in one of those no I'm sorry and I want the first one
uh this is one
of that night wow look at all that detail yeah I it was a really really good night
because the scene was kindly perfect and then it was really
tough healing Buenos Aires in the premise of Buenos Aires the our skies are not too much good to do planetary so
it's really really lucky if you have really good one
so I was continuing and doing pictures of who'll be there
I don't know no it wasn't sorry if
I can see the the the files oh yeah uh this is one of the finally
another night and I think this is one of the most
yeah that's beautiful you can see all the limb darkening lots of belts
storms I hear some moon right I think it was I don't remember it
was EO but I was to to get this kind of picture
that was practicing practicing a lot really really almost you can see the
fourth the fifth yeah the 12th the 14 and continuing
[Music] but I think the last ones
was almost like this sorry
and I I can't even remember the finally
emerges that I did um
here's an example
oh that's cool that's really cool I was devastating too much almost 10
minutes of videos yeah and then doing this animation this is manually animation
uh because I want to have more details on the planet and you can see the the
storm going by you know I my goal was or
try to go it was find the the great red spots
um I don't remember it wasn't one of those piles yes I think
but I don't remember
and I was
you can see there's a lot of videos that I use and almost
a 700 megabytes each video so you can see you will need too much
um now I don't remember the the file that I
did you know I I don't know it was in October uh because in this case I was
practicing with the Barlow 2x I think hmm
so I think
this is the using the 2x Barlow and this is I think the my last one
um Jupiter that I did you can see in this case is EO
a passing by in front of Jupiter we can see their great red spots
and this is almost a one and a half hour
a videos of one minutes hey look at that oh that's so cool let me Zoom it yeah
I love that you can see almost like kind of disappear but the shallow reveals that
there's something in there you know imagine to be in this surface yeah yeah
this Eclipse watch it go there yeah yeah and you you know this occurs uh
a two at one time every two half days
almost and because the orbiting the orbits of
EO is really fast so the the moon
in two and a half days passing by through this place so this is almost at
the two or three days a little more later of
the opposition so if we if I could take pictures of
this same a um passing by of EO the shadow will be
almost behind the moon and not this a more like at the
right of the Moon so that's a because of our
position in our orbits the perspective like like I like to say it
um I don't know what no this was some rotate the rotating image but I couldn't
have really really good ones I don't remember one of the
because when you derotate with some uh
and there are some moons sometimes the software doesn't help too much and you
see this Moon split splits and what
um now anyway I was doing this and of course I was
taking pictures to the Moon practicing a
sorry practicing with videos trying to to get
some details and well uh
a September uh was a really really good month to practice in planetary
and ah sorry I did a show the the the back
stage of our last our star party that we went in Alberti let me find some
pictures um it was here it was at the final of August we went we
we are almost 10 or 12 people that we met in Liberty
and this is where are my pictures that I did
that night this is a light pollution from bragado another city and this is
one is from Alberti but here
one two three four five almost six or
seven years and we have a really cold night
and almost six minus six Celsius so you can
convert in Fahrenheit I think is almost 24 Fahrenheit here
almost like that um was I this was sticking with my dclr
camera I was trying to do some it doesn't have a really good sensitive
sensitivity this Nikon d80 but anyway you can see the the
Milky Way putting Over the Horizon this is when
the the Milky Way goes down here and you can see it's really in
parallel with the horizon and
then I put my Nikon on the Oscar lens
that I have uh trying to do some deep Sky objects that I want to do is Android
Mega Galaxy but I I was struggling with the the no
the guy didn't but the mount it wasn't really good uh but anyway this is the field of view
of that Galaxy it's almost at the North and then I say
to a friend of mice you know you can put your Nikon and use my lens I
I I was doing with the these high objects so he put his camera and take
pictures and everything and he really liked that so when the sun sounds like a lot of
sounds like a lot of Northern targets to be down there wait a minute it's kind of like us
always wanting to get to the southern objects right you know all shot at all those Northern
well and I don't blame you because I think this is the time of year you get to see more Northern objects better and
you know in the northern hemisphere all the time so I don't blame you
it's October and November I can see Andromeda I'll try to capture it and
then bye I had to wait for the next year but
Orion for example I can start to taking pictures from now or maybe the last
month and a almost March or April I can
still uh capturing you know there's a lot so yeah that's one of the one of the
constellations that I think we have in common with um when we can capture it because um I think it's about the same
for us
well this is some a backstage pictures this is almost done
but you can see here there are some ice creams oh yes it's cold it was cold you can see
yeah I are in my car in this Bank
you can see this white yes no but you are a dedicated astronomer yeah we have
uh of course we have matters to to to warm up but I think it wasn't too much
but uh yeah this we went we went to the sun goes up
because we was freezing and this is my gear
you can see that the The Ice yeah and the spikes next to the cameras though
yeah yeah the cameras are easily I don't like it called yeah their eyes cold so no thermal noise
there exactly you know I remember the the percentage of the the power that I
need to use the the dedicated camera it was almost 10 or 50 percent of the
old Power to use the the to freeze it
you know because it was really really freeze here and well this is a picture that uh that
Ariel Rodriguez a friend of mine took of me you can see me is I I was really uh red
in my face because of the cold weather and you can see the there's still ice
even is down
and this is another picture that also I didn't already took off of
me with my gear this is a to to do some social pictures
on The Social Network because I I ask a lot of times to take
me pictures like this and he said okay this is the night so
uh I I was illuminated with this oh that's cool left yeah it looks good
I love that shot that's great you can see the the almost uh let me
find it out here this is the Southern Cross
and you you can see the the charcoal bag full sack ball sack sorry
and well the rest of the Milky Way it was above our head here I was watching
the northwest so this is a social media picture that I
asked him to to Jamie so he he said on the boat cover it looks
great yes so this is the atropica his his Facebook Adriel Rodriguez
so everyone find the picture that he did and also I have some pictures
I want to to invite him again to because he was doing pictures of that night also
if Ariel wants to to share with me some pictures that he did because they are
really really good ones they took pictures with the observatory
a building and what uh
uh sorry I and now I was with my gear outside
uh because I want to to practice with this a update
um software of a cwo and I was pointing to the Moon
so this is the live view from the Moon
a video this is a live video right now
and I can move the gear inside of my house
so the objective tonight is is to
practicing and see if I can do some deep Sky objects
uh you know I think the planetary season is is crossing over but for me it's
almost done I have to see more more later with uh with Mars but
I want to get practice to 20 days more
at the end of the November so if I can see if I can do some galaxies
um I don't know how to say when you take pictures of the area but a like a square
and you mix them like um I don't know how to say sorry
so so I want to do some Galaxy clusters there have really really good shapes
so what that's uh for me for tonight uh thank
you again for inviting me and I hope you you like uh well my my work absolutely
absolutely that's great thank you so much um uh Maxie
um now we're going to go to a 10 minute break and up next is uh Molly wakling
with her famous astronomally uh program and we are uh she's back there uh
getting all prepared so it's great so we're it'll be a good time
to get a cup of coffee or a sandwich or something like that stretch your legs just a little bit and we'll come back
with a lot more
well I'm gonna go do just that good to see you again Maxie it's good to see you again all of you
say Sad Molly
hi Molly Molly foreign
we can hear you
my correct microphone's not showing up in the list so give me a second no that uh now we can hear you so yeah this is
my crappy microphone good microphone oh you got nine minutes
left so go microphone but I have a Blue Yeti that I would like oh well you gotta
get that working the fancy microphone it usually works I don't know why it's not showing up in my list on on Zoom today
um what happens a lot is I'll log into zoom and it will latch onto my um Oculus quest uh microphone instead
which is annoying it's not even turned on I don't know well it's in sleep mode
um okay why hmm
all right I'll let you figure that one out yeah
let's see here
okay um
foreign
yes well you're talking in English that we are watching the shadow of EO
IO okay
this is why yes we we are going to make
a low Safari in Spanish expression
yeah we have to do that sorry sorry we started talking in Spanish but not in
Spanish Argentina and Spanish yeah my Spanish is Rusty and I'm
no I'm much better I'm speaking it than understanding it
very very fast in Spanish I think yeah I think Argentinian Spanish is more difficult too
we are difficult and my microphone's not showing up on my
computer and I don't want to restart so I'll just use my my webcam microphone I guess which is lame because I know that
microphone has a hiss or so I've been told no but I can hear
you yeah really good my customers all right I can hear you fine
um yeah I know the feeling as soon as you're done you're gonna try the other mic it's
gonna work and you're gonna be like yeah I really don't want to reboot my
computer though because I have a ton of stuff open yeah and you're on in five minutes so well I'm not gonna reboot it
right now but even after and uh my research code is still not
working that's great so I'm trying to do three things at once
here also figure out why my nine and a quarter Edge HD has a single
diffraction Spike I've been unable to figure it out it
happens intermittently a single diffraction Spike too many problems going on it's a line on both sides of
the star but yeah it's been going on for months and but it's kind of intermittent sometimes it's not there sometimes it's
there and I haven't heard the Optics train apart there is nothing in the Optics train I've tucked my Dew heater
cables from for the do heater ring um yeah I've got them like velcro to the
telescope so they can't hang over which I thought was the problem originally but they're definitely not full Spike
spectral Spike [Laughter] I really can't be
can't face drives you nuts I've created a couple images with it and it's annoying but it works but my the
one I'm trying to process right now will not register and um that's problematic because I owe a
couple of companies some reviews on their filters and they would like their data so I guess I really need to get
this thing figured out um yeah so I don't know why it has Wonder
fraction Spike going out well you think of a telescope especially an astrographic system all set up you know
there's so many things that have to harmoniously work uh you know and
there's uh there's always something that they're that you're trying to uh optimize or or remove a problem somehow
you know and uh uh this is true for amateur astronomers and professional
astronomers uh you know so it's something that they're always trying to get figured out
but uh but it's it's amazing what uh people
like yourself get um you know uh and you know
blow away with other others of us that see your work you know so uh I really
enjoy it I've gotten some results recently uh so I went to the Okie Tech star party in
September and got some really great really great data sets that um have just
been awesome to process like yeah on a I I've I've uh I was borrowing a 400
millimeter Nikon F 2.8 camera lens like an 1100 2.8 okay by 9 000 camera
lens yeah you know I I want to point something out
here you know camera lenses can cost way more than telescope lenses and I I
haven't been able to figure that out really yeah I mean they have a ton more glass in them and they're really like
they they really do make a difference for daytime images like I got to bring
it I went to South Africa for a conference and I got to bring it on a day-long safari drive and it really they
really do make a difference in the image quality however nighttime images that
can get a little tricky because the stars are such a a huge test of these lenses yes and when you have 114 glass
elements in there it's not kind to point sources no but actually so I was using a
qhy533 camera that I'm testing which has like a one inch square chip and because it's so small I'm right in the middle of
the of the lens field of view so scarves are actually really nice because I'm in
the middle and those images came out really well that's cool that's cool there are
however some really great camera lenses that make pinpoint stars all the way across even wide open so the Rokinon
series are very yeah and they're cheap as far as lenses go and Dr Chivas far as
telescopes go um I have a 135 F2 rooking on that just
kills it and yeah I mean if you put a big enough sensor on there it does start to comb out toward the edges but on my
fourth third sensor it looks pretty good across the image um it's when you uh put it on a aps-c
sensor you can kind of start to see it um but yeah if you crop it down it's
it's pretty brilliant right it was so dark so Okie text is
darker than Texas Star Party um by a little bit um because they don't have all of the oil fields around them
that yes starting to get and so uh and I have a new camera that I got earlier
this year that this is my first time bringing it to a dark sky site the zwo 2600 and when I got home to processed
that data I thought something had gone wrong with the camera I thought I was having a USB problem because I was seeing all these horizontal lines in the
subframes and then I realized that I hit the noise floor light pollution was so non-existent I
literally hit the noise floor of the camera I was seeing the read noise in myself wow
wow because I look I blinked to the frames and the lines were moving every friend so I was like okay yeah that's
that's just read noise like it's gonna process out it's gonna be fine and and yeah those images from the 2600 are so
low noise even even from here um under bordel7 that camera
is much better than my 294 so I've been really really happy to finally have that hey I don't want to interrupt but this
next uh these next two videos are about the meteorite that hit Mars in decem on
December 24th last year and they just kind of published this data so here we go this is uh this is an
audio uh sonification of the meteorite hitting
um uh you know the hitting Mars which created like a 4.0 earthquake that both
Rovers detected and uh and then there's a there is a
visualization kind of an animation where they go make like the circle around uh
the impact crater so this is the biggest impact crater that they've ever discovered and it's I mean this is
practically real time uh well not real time but but very uh very new kind of
stuff and so here we go
[Music] boom
long earthquake longer than the ones I felt in
California yeah this is barely enough to wake you out of bed but
in California that's for sure and then this is the visualization
all that white stuff is Ice Water Ice um
hundreds of feet across this crater look at the way it kind of
dug in kind of came looks like it kind of comes in a little at an angle and digs in
oh yeah
that is cool that is too super cool
well we're back uh got my jacket on it was starting to get a little cold here
in the office but um uh anyways uh happy to bring back on Molly Wakeling for
another astronomy uh episode um Molly is uh uh you know she's a
scientist she she is an amateur astronomer a fantastic astrophotographer
um and uh she's done lots of uh broadcasts on global star party but lots
of other programs that you can find on YouTube um and other social media channels
um and so uh Molly I'm going to bring you on and give you the stage thanks for coming on again to Global Star Party
yeah I'm Glenn here I I was I always go back and look at the dates of the last uh
slideshow that I made because I I put the date in the title and I realized I haven't been on since July oh wow so
it's been a while yeah that's for good reason though because I had my uh prospectus defense in uh August
um or it was supposed to be the end of August ended up being bumped to mid-october um but I was seriously writing my
prospectus which is like the first three chapters of your dissertation um and so I had that uh defense uh last
month which tied up all my October time and uh I passed so I'm not PhD candidate yay
um and then I was gone the whole month of September going to some conferences and then to the Okie Tech star party so
that was a lot of fun I have a themed shirt on tonight
um it's uh it's actually like the digital check it out encoded as like the
planets and and Circles of color very cool where did you get that uh there's a
website uh called uh um svaha that sells nerdy like dresses and shirts and skirts
and stuff like that um that's uh they've got some pretty fun stuff on there very cool to me it doesn't look so nerdy well that must
just show how much of a nerd I am yeah I I fully embraced that that I
fully embraced it since elementary school so there you go it's great well I will share my screen
okay load the rest of that slide there we go
all right it is November and I am finally back yay so I want some images
have been processing recently have been on the North American nebula because I took one at uh okay Tech Star Party
I took one from my backyard I'm testing a couple of filters for Aunt Leah and opt along so I wanted
to get some of the same Target on the different filters so I've got North American nebula on the brain so I
decided to do this month's or weeks or however often I come on here these days this uh quarterly report on the North
American nebula yes uh all right so uh it is a large
emission nebula up in the constellation cygnus uh it's also known as NGC 7000 or
Caldwell 20. a nice mgc number to memorize unlike a lot of them it's a very large emission nebula and
like most emission nebula or I think pretty much all a mission nebula it is a stellar Nursery so new stars are being
born there and this is a uh the image of the background is a um uh an Esa image that
see it's a combination of um of infrared and Optical data put
together into one cool image of part of that region all right so where can you find the
North American nebula submission it's up in cygnus specifically it's up off the end of deneb and uh yeah it's it's it's
very large and I've got some observing notes on it later um as part of a very an even larger nebula complex all around
anywhere you look in cygnus you're going to find Nebula if you point your camera anywhere in cygnus there's going to be red stuff there in the background and
it's an extremely star dense region up in the uh not quite in the core of the Milky Way kind of out more toward the
side which is why we see it so nicely up at Zenith here in the northern hemisphere a little more difficult for
our friends in the South to reach kind of gets lower on their Horizon um and that's that region of the sky
cygnus it has so many stars that's where the initial Kepler mission was pointing to go find all the exoplanets because
they had they kind of searched one degree one square degree up in that area and there's like tens of thousands of
stars and then thus some thousands of planets in that area so very star dense and very nebula-rich
region here's a like to put it into more context an actual picture of the Milky
Way overlaid with uh some both the consolation of cygnus and pointing out
where some of these nebula are uh thanks to Astro backyard so we have deneb here deneb and Saturn
are pretty easy to kind of point to to see in the sky even if you're under light pollution they make a nice pair
and then up off uh to the side of the neb is North American nebula part of
that is the Pelican nebula and there's just nebulosity absolutely everywhere I'm actually working on a large Mosaic
of that region that I have a lot of data for that I have had have not yet had time to process because mosaics are hard
and this is my first time doing one so um hopefully that'll come out eventually it'll be really cool hopefully
uh so it's called the North American nebula because it is shaped somebody
realized it was shaped like North America now the way I have always seen it look like North America is different
from apparently how everybody else sees it as North America so I'm gonna put it out my way first and then show you what is apparently the correct way to see it
which I just don't really see honestly I've always seen it this way where like
um the region up above kind of the main maybe the region it's like Canada and this dip here I think is the great lakes
and you can kind of see the west coast and the east coast and I've never looked at it this way yeah it's apparently the
correct way to do it is upside down yes um where the Pelican nebula is like Mexico and the region that looks like
the Great Lakes to me is apparently the Gulf of Mexico which is like all fine and stuff because it totally leaves out
um sorry uh not the Pelican image this is the cygnus wall the polyconomial over here is totally left out of the
constellation or out of the um out of the shape of noise America which I think is just rude because the public nebula is so fantastic although the cygnus wall
is pretty cool and yeah that's part of it but we'll just call the Pelican nebula
Europe say again call the Pelican nebula Europe well from this angle it's almost more
like North Africa well no maybe maybe no Europe's much more
it's almost like the top of Africa anyway moving on from that controversy
yeah yeah is it a controversy it is now yes
it is I declare that The Irregular District you've changed all of America
change the globe that's what people are seeking anyways was change right yeah this is It's a global star party so
everybody's going to look at it now right
the view is completely messed up oh well we'll go back to the Molly wave that's okay that's that's for a while process
of science that's right all right so some fast facts it's um
magnitude four although it's kind of hard to put one magnitude value on the whole thing because it's got It's got dark nebula it's got some brighter
regions it's got lots of stars um but I guess it's sort of averages magnitude four
um however it's so large that you're not gonna see it like you would a magnitude for a star because it's so spread out
that you can't really see a naked eye unless you have um like a ultra high
contrast filter under Dark Skies it's uh on average 2500
light years 25 2600 light years away and December was actually in question for quite a long period of time uh it was
thought to be somewhere between one thousand and three thousand but then the Gaia survey was able to pin down the
distances of several of the stars in the nebula to within an order of about
15 20-ish slot years so we now have a much nicer on how far
away it is it is an astounding 140 light years across which like you think about
how big that really is it's really mind-blowing like how enormous this nebula is like like you know when we look at Messier 33 uh the um triangulum
Galaxy and there's some of those enormous nebula regions that have their own NGC numbers like with other people
looking at our galaxy they probably see the North American nebula like one of those like one of those big nebula
regions in m33 in fact that size on the sky is 120 by
100 arc minutes which is the same area as about 13 full moons of area on the
sky so if you ever get a chance to look through um uh deep Sky dudes monocular
um uh night vision optic you can actually see it when he puts the hydrogen Alpha filter on there and it's
very cool just to see it up there in the sky enormous the size of many full moons yes
and the red glow is from ionized hydrogen gas which is very common throughout the Universe and all these
emissionable that we have um is that red glow is coming from hydrogen gas whose electrons are being
Stripped Away by really energetic light from those newborn stars and when uh
when the electrons are dropping back down in their energy then it's emitting
this characteristic red light so I always like to show what these objects look like in other wavelengths
other than Optical and I looked through the Aladdin application which has
overlays of like every Sky survey every done ever done in every wavelength of light
um but a lot of the stuff like in X-ray and gamma ray and stuff is not very high resolution so I grabbed just two images
that I think show something cool about the North American nebula and that is the radio image in the infrared image so
the radio image is actually one of the higher resolution radio images that I've come across and it's a combination of
the Canadian and very large array Galactic plane surveys at the 1420 megahertz line which is
another emission from hydrogen gas it has been ionized so this is a much lower energy transition uh which is why it
emits in the radio which is a much lower energy of light than the optical light that we see and and you can see
different features than than you can in the optical light but also some familiar ones here is the cygnus wall and it
looks quite similar in in radio light as it does in Optical but one thing that's
in the radio image that's not present in the optical image is this bubble here and I didn't get to go look into what
that bubble is but these bubbles exist uh you can see them all over the plane of the Galaxy and above and below it in
these radio images and um they're like oh gosh I remember
hearing about this in another presentation recently um I can't remember what they are
shoot I wish I knew that I'll take a look but yeah there's these radio these radio hydrogen bubbles all over the
Galaxy uh over here on the right is the infrared image from the Spitzer
telescope and it's much more zoomed in because it's got a smaller field of view and this is probably a mosaic of Spitzer
images but again you can see the cygnus wall over here kind of that famous Samos to see it as like a flying eagle kind of
shape here um but a whole lot of other structures don't look as familiar
um I think this might be the Pelican region but one thing you won't see here
is that uh the Gulf of Mexico slash Great Lakes uh pool of dark nebula
because infrared light punches through the dark nebula tends to block the optical light so we actually see the
glowing gases that are behind and within the dark nebula region
um up in this area so that's it's kind of cool like when you see things infrared you're seeing different things
than you can in the optical because that light will pass through all of the dark light absorbing dust that that the
optical light will not pass through so a little bit more science for you so
um looks like I covered up a little bit by the picture there yeah so uh ionizing so
the stars in uh in these nebula are what
are causing them to Glow these nebula to Glow this red and
for a long time people were trying to figure out what star or Stars specifically were causing the red glow
because they have to be really hot in order to be emitting enough ultraviolet light to be able to light up an area
especially an area that large so um it was it was uh so Edwin Hubble
thought in 1922 that deneb might be lighting it but it's far too cool to
actually be lighting that nebula it's only got a surface temperature of 8 500 Kelvin and the star needs to be at least
30 000 Kelvin for this amount of ionizing radiation uh in the ultraviolet
and finally after doing a a lot of uh
searching for it it was spotted in the infrared survey called two Mass
and they finally found a star with that temperature that fit some other characteristics of being the star that's actually
lighting up the majority of the nebula is it is star j2055 1.3 plus four three five two two
five if anybody wants to name it feel free that is its name
um it is uh forty thousand Kelvin in temperature now it would be as bright as
albirio if it was wasn't hidden behind the dust cloud and that's why we had to look for it in an infrared survey so we
didn't see it optically because it's hidden inside of the desk cloud and I've
got a picture on the next slide with where exactly it's at and from within the dust cloud it glows at a magnitude
13.2 um but if it were not in that cloud it would be as bright as alberio
um it's dimmed some 10 000 Times by that dust cloud
so it's it's roughly uh from from what I could find quote off the coast of
Florida and looking at another graphic I found online it looks to be approximately here uh somewhere behind
this section of dust cloud is the star that's lighting up the entire nebula
which I remind you is 140 light years across wow it's insane this ultraviolet
radiation is just spewing out of the star shooting for many light years across uh and and ionizing all this
hydrogen gas and causing it to Glow uh lit by like one star
Hubble just uh surmised that Dana because it was so bright was lighting
this up I guess correct yeah yeah um but it also wasn't really really centered on the nebula either which is
why people were kind of doubting the idea at first but then once we were able to measure its surface temperature by
using spectroscopy then um they're able to see that it wasn't hot enough to be ionizing this whole
nebula but yeah because the net was so bright it was initially thought to be the star that that was ionizing the
nebula all right so if you want to observe NGC 7000 aka the North American nebula
visually uh well so the best time of year is actually it's because it's so high up in the sky for us Northern
observers pretty much up at Zenith you can observe it for a large swath of the Year depending on how late you want to
stay at it's a bit of conservative like maybe at a star party or until two in the morning so you can observe it from
May until December um and uh now observing it visually is
quite difficult because even though it's bright it's very spread out and the way that a parent visual magnitude is
measured it's actually if you summed all the light together it's that magnitude so when it's a small star magnitude four
is really bright but when it's spread out over the size of 13 full moons it's
really dim per unit area so now you can't see it under very dark
skies as a foggy patch with a pair of binoculars and you really need an ultra high contrast filter to make it out but
because it's three degrees across um you either need a really short focal length telescope or you know really wide
wide field of view telescope or a pair of binoculars with that UHC filter photographically though it's quite a bit
easier to image because that red really pops out on at least on either modified
dslrs or on astrophotography cameras that don't block as much red light and
you can do it fairly well from my polluted areas if you use a multi if you use it either like a set of neural band
like hydrogen Alpha filter or if you're using a multi-nural band filter with the color camera is really the best way to
do it I think you can do it with just a light pollution filter but it's so dominated
by stars and that red is so hard to get through the light pollution without a multi-neraband filter but it's just not
as impressive the picture I had here in the background which I've made less are made more transparency read the text is
what it looks like uh when I've tried to do it without a narrowband filter and it's kind of hard to make out the shape
and there's just so many stars it dominates the image but the one I have on the next slide was done with a
um uh a filter that lets through more of the kind of narrow band light in
addition to some of the wideband light um which I'll show in a second it's best done with a larger field of view because
again it's it's something like three degrees across and um or you can Mosaic it
and uh kind of capture and higher resolution with a longer focal length
telescope like a refractor so um I always like to show my best image of it
of whatever Target I have this is when I just acquired uh like two weeks ago from
my backyard using a filter a brand new filter that I don't think has been released yet from
antlia so uh you're seeing the results of one of Atlanta's new new filters called the tri-band RGB Ultra which I'll
be writing a review on here shortly um taking this is with my zwo 294 camera
color camera on the Rokinon 135 lens that I was chit-chatting about earlier
um it's about four hours 42 minutes of exposure time from my portal 7 backyard and yeah with with with emphasizing the
narrow band portion of it it stands out a lot better from the light pollution background and uh it doesn't get too
overwhelmed by the Stars and yeah that's what I got
wonderful wonderful okay great okay so
um let me see where are we
right now we're going to uh Brazil uh we're going down to Marcelo Souza uh and
apparently marcelo's quite happy that they have a a new president uh so I'm um
I'm pleased to bring Marcelo on and uh uh archella congratulations on the
transition and uh I know not everybody's happy with this but uh I think that I
think that you are because of the uh uh that uh this new president is very uh
centered on science is that right oh and you are muted Marcelo
sorry there we go foreign
because you have problems and support for Science and now
we'll begin next year the new new presidents he already was President for
two times here in Brazil this is third time that his rule at present and the
house of the population that supported him in the election then to have part of
the population that don't support him and the we have problems now here but
is only for a few days I believe and so we are we back to normal
but I'm happy in the almost all the teachers and the scientists see in
Brazil are happy with the results of the election and now I hope that's the new future man
the close future that you have we have support for the application of us yeah
science this is the most important that I hope that you're happy
yes let's see what's happening let's see
what happens here but today you have a trucks in the
street it's closing road is having They didn't accept that they
that won the election the part of the population is make the best
but uh it's only for a few days man everything you'll be fine in few days
yes a little bit back to normal I believe so I hope so I believe so
and yeah now because even in the spirit
of Elections we organize the uh ceremony for the close we are closed
the project that we developed with the support of the
Consulate of the United States is a project
okay young stars of tomorrow and then we had the opportunity to
recognize yes a big event now with participation of the the range of the
Department of Education from six seats the year that's where you developed the
project and I will show here a report that was transmitted in Brazilian TV
about the the events that you organize and now you see you can see the students
that participate in the project they developed the
uh animations develop the apps developer
astronomy projects you organize main observations including job salvation of the eclipse
and what is fantastic in Brazil That's it ever motivates me that you see that
most of the people that participate in astronomy events are young people
then this is something that motivates us that's your heavy a better future here
in Brazil because the students participate in all the events that they organize associated with education and
science United States consulate that participate
in life during this animal and the uh what is fantastic that this
event happened in this field of the election here in Brazil then we had the
opportunity to organize these events these are the students who vote in the
events most of their lives far from Big centers
well here in Brazil and the it was fantastic to have the opportunity
to talk about the astronomy and science to them
and now uh something that's very important for us
also is that you have your support of the press here in Brazil and the local
TV channels and gave the opportunity for the students to talk and they showed the
students that developed Pro developed the my educational material that you produce
and this is a fantastic opportunity for us and fantastic you can see let's have
almost 100 people in this ceremony that's why the last events after this
project but the seats I already invited us to continue with the project next
year in these seats
is there and we are planning now to build a big
uh anonymity near the beach in front of the beach
well then we are beginning in December beginning this summer here and we hope
before the beginning of the summer we will have a big analimatic sandal in each of these seats
that participate in the project we already have an app that he gave out
informations to produce the analimatic sandal
and this was the Secretary General of the Department of
Education of another city I go here now I respecting I haven't
I ever tried to follow what's happening on Mars
man and now you have something that he
promised will have a solution but a question that we don't know the answer
until now is about the
and demos we yet not know if they are asteroids
let's see or during the the gravity of
the planets or as catch by the planet now is this is a
small move or if they are part of the planets beautiful through the process
that is the bond planet in the same time you had the the
lose these two moves now that is not most and sometimes later I already decided
here how big I think that in the beginning of 2022 I am a global star but is this book
made something that I ever remembers by Jonathan Swift he wrote in
1726 and in this book
100 years before that's the moons of
mass were discovered who wrote this part in the gullible wires
into the imaginary Island Swift says and I don't know if it's correct way
it's saying yes have discovered two less stars or
satellites which have all around Mars where of the innermost in is distant
from the center of the primary planets exactly three of his diameters and the
outermost five the farmer evolves in this space of 10 hours until later
in 21 and a half an hour this is why something that nobody can can ex
explains why that they consider these
two moves from us wow the time of the evolution around the plants is almost
all the time that you have enough but I think that he he likes to participate in
a lottery and put here I believe it is and something that uh two moves yeah I
think that you have a logical explanation for this because what you have because you can imagine that if
they knew the four moons the four biggest moons of Europe Jupiter then
they imagining one moons do you have to have one move then you have two moves
UMass and you have four months sequence right I believe that this was
the origin of this proposed but nobody knows why it did this but something
fantastic to him and these are the only 18 17
how [Music]
foreign
[Music]
21 hours and a half but something fantastic yeah that is
fantastic how he imagined this right almost one
hour 100 years before 100 years before they could possibly even see it yeah yes
this is a big mystery but you can't imagine something like why
he imagined two moves but the numbers and the he proposes something fantastic
and now everybody as we don't know the judging of the most
if they always they burn it with the planets or
asteroids and now they might Express is analyzing the subsurface of the planet
and it found results that nobody knows how to explain
there didn't solve the mystery but he found the next an extra a
different kind of a structure in the subsurface then we need more studs now
to know what's happening but in 2024 AG you have another mission to explore
the default moves of the
Mass Andy is from Japan and what they will do is they will catch
they will bring to Earth material from Jimmy to be analyzed here like they did
with an asteroids hayabus and then if you receive it I think that
if we are until 2026 or the end of 2005 will receive it will come back
to us bring part of your material of the surface of judismo and there's I
think that should be the first time that you received yeah surface
samples from moons of other planets
and another information that I don't know if everybody knows that's the the
inside Space the site probe is finishing the mission
and they will stop to send the data from her
so he's near the end of the information and from for the people that live United
States now you have a next week you have a total lunar eclipse
November 8th I believe that you'll be the time me the day in United States in
the Coast Pacific Coast I believe because it's the best place to see the eclipse I don't know if you have people
already being organizing the observation but they'll be a total lunar eclipse is
there a fantastic moment to make organized events of the
popularization of astronomy and I believe that in Canada Mexico and the
United States you have a great opportunity to to see this eclipse and
part of it yeah in Brazil you will not be possible to see but we are organizing
already organizing because you have when you have an eclipse some I put here to
remember to talk about this because generally you have two eclipse or three eclipse in sequence
they are not they never comes along this is something that's important to
remember ah this image that I show here is for the home page time and date that
is uh is a difference sometimes foreign
15 days before more or less we have these new eclipse and we have you ever
you have two or three Clips in sequence and what they don't come along easy
research this one because they cross the opportunity of the Moon
evolving around the earth and the Arts of the Earth around the sun when they cross drugs you
have two opportunities now during the full moon and the new moon to have the
eclipses then during the new moon have the solar eclipse is
lunar eclipse then I have the opportunity to have you in sequence but
this is eclipse now this will be our opportunity next
year in another eclipse in October
watching 2023 we are already preparing to to see in our region here in Brazil
it will be partial but you see here you have January eclipse in general of
Brazil and for us here you'll be a partial solar eclipse and we are
preparing for now the structure to observe the clipping out that you will
be visible in all the country most often than a partial work solar eclipse and in
the North Region of Brazil are total solar eclipse in composer you see like
this let's see here how much 40 percent of the the sun will be in the shop
um this is what I would like to talk today thank you very much all right it's a
great pleasure ever is a great pleasure to be here thank you
wonderful wonderful okay all right so um I think up next we have uh I think we
have Adrian uh Bradley coming up here and um uh Adrian is uh been Faithfully
on global star party now how many how many Global star parties have you done Adrian I've lost count but it had to
have been um well if I I look back I see global
Star Party 54 so 54. yeah since uh David
said check his work out I think it's been so you figure another so 50 or so
of these Global star parties yeah um and um
I've enjoyed being in every one I often show up early and stay late till it's my time to present
usually because I'm trying to figure out what part of uh my Cosmos world I'm
gonna present in right and so I come up with something so so I have a couple of
things and hopefully I can keep it relatively brief I'm actually I actually
think I can pull off showing my process as it stands today
and also show some of the uh some of the conundrums that I work on as I do my
um nightscapes I'm always looking to get closer and closer to presenting
these nightscapes the way that the sky color looks the way that you might see
them if you had slightly super human Vision so there's certain things you
just you aren't able to see as well um certain portal zones
um and then I'm also curious as to the results I get and whether or not I'm you
know the night sky that I'm showing our natural colors so I'll go ahead and
share my screen and Let's uh
and I'll begin to share what I am talking about recently
um I'll start right away with an image that I took recently out at Point o'bark
Lighthouse Park and I found this image interesting um I always image parts of the Milky Way
other than the galactic core and um I've gotten to where my
Composites are starting to make some sense so these a lot of these photos are
exposure times of two minutes where I'm and I'm shooting
at lower isos I've learned through being at Okie text I had met Molly when I was there and being at Okie text
with a long exposure your camera pulls in the same amount of data regardless of
the iso you use but if you do use a higher ISO you're basically telling your
camera to stretch the image for you now I think there are problems if you
under expose the other the other thing with that is you have to take a lot of frames in order to get a bunch of data
at ISO base so what you do is you look for a happy medium where your camera
stretches your image to a point where you know all the the data is recognized
but you don't clip any data and you you
know you're using natural lighting um which a lot of this lighting came
from um and I'll show you I'm out at a lighthouse and when I turn around
um this is the view turning around the cygnus um
region setting and I didn't quite get to North American in here I don't think but
uh you have all of this light does this bright red light here he's got a bright
street light you've got a lighthouse light which is now more potent because you're further this time I shot further
away from the lighthouse I usually shoot close to the lighthouse this time I'm shooting away
and um I've got this glow over here a lot of this I believe is Sky glow but
maybe there's excuse me maybe there is some faint Aurora I mean you've got some red you've
got some greens here so we could be looking at very faint Aurora I've shot it where it's been more kind of pinkish
looking yeah yeah it's pinkish looking and then so is this
um when I look at the ground here everything is the proper color so I when
I do my white balancing you know you can look at the sky and say it should be a
certain color but you know when I
when I look at it I go is this correct if this is correct then this is close
um so the sky truly does have this darkish Hue to it but now
let's see let me go back there's okay Tech pictures here
and [Music] here are my October pictures
where I took this photo and we'll show this one again
so over here you've got a you've got the light the light pollution here
you've got this grayish almost gray metallic blue color and over here
as if this part of the Milky Way is dividing the area of the sky that's affected by
Sky glow and the of this part of the sky that you know there's very little Sky
glow and it's it's almost a different color now when I went down
um let's look for let's look for that again October
when I went down the lake I took this image
I'll move this over here and you see there's a more uh you still see some Sky glow over here but and you
still see data but it's a noticeably Bluer tone this these colors look correct the lake color at night and this
bright area across the lake um you know casting all of this light
looks correct well there are ways to process the image
that again it's based on how the histogram
looks and everything else I tried it again and I came up with this which when I go
on my memory of how it looked
this to me feels a little closer to how the eye the color that the eye sees in
the night sky now it doesn't necessarily see these dust bands and again I always
say on global star party that um the Milky Way season doesn't end just
because the galactic core is gone or does not stay in the sky long enough
there are Treasures to image over here and including all the parts of Orion a
lot of what you'll see is just Orion in this part imaged and with these colors
super saturated nothing wrong with that at all um an article that I read about processing
um you know has has some words that I don't
tend don't think are good words to use when it comes to processing images and
those are the words wrong saying something's the wrong color right the wrong you know even though this is
so is this natural maybe maybe not this was after colors
are all colors right yeah and see this this certainly looks correct so
you know the bluish tinge in the sky you know definitely comes from a
location and I I felt like the Bluer my initial
results the um it must be an indication of mortal zone
so once I get a sky meter an sqml meter
I'll be able to look at that but then again
when it comes to processing and you'll put pop this up one more time when it comes to processing
you know you can you can make your Sky look the way you want
case in point go back to an old January image so
so here's that blue tinge and you look at this and you go
well this is obviously winter I could say that I was leaving the sky blue for effect
go back and try and edit it a little bit and I pull some of the blue out this
this begins to look like colors are a little more natural so
the color of this is a is brown you know it's at night so
the snow you know you can see the snow this was this was again January I
recently went back to try and reprocess it and I ended up with this and I will admit that this is a correct
color this is what it looks like when I see it this is still here a lot of light
pollution and the sky is approaching that
certain there's a kind of a grayish orangish Hue to the sky when it's um
you know when it's processed using the methods that I'm using here
um you know you end up with that's sort of the sky that you end up
with um looking at this image
um Darkness Darkness in what shows up yeah here you have yeah you have this
beautiful image at Oaky text of a Mesa and the sickness region there's the
beginning of the Bulge and this is the North American nebula and the Pelican nebula showing up there's the cygnus
wall right there but um I come back home to
um let's see I came back home
and what I want to do is I want to move this over here and I want to move that same
this is so this is the cygnus region image again
and you can see the dust lanes and the darker skies are a little darker that's
okey text back home at a region where I believe to
be Portal 3 and it was it was a very good night I just switched over
to a different image looks very similar
very very similar but this was maybe one or two bortal zones different
this isn't back in Michigan with fall colors present and
um the scene that I have ends up being a very believable this is
the front yard of a cabin in the thumb of Michigan
where my priest lives and uh his uh
it was dark there I had planned on going to point O bark Lighthouse Park that night and I just stayed there to observe
and to take images from and um by the way you'll be happy to know Scott
that this was done um with the explore scientific
um pmc-8 Mount that I had that's great the ISS 100 yeah thank you it tracked for
two minutes almost flawlessly this is all Focus issues and it did
it did pretty well and it also
tracked really well I don't recall if I used it for this shot I know I brought it out to take images and
um it did really well for
um I can find it there's one other there's one other shot that it did
really well for this was the PMC 8 mount and a composite track the sky
and then I shut it off in order to just take a long still of me looking out at
the lake so this tube is an explore scientific shot and uh it's it's made me consider doing
more wide angle photography with it yeah I love that shot it did a solid job
um you know there if I have a little bit of Stars being oblong I'm okay
it uh I think it did well and um
just to let's see finish couple
more images and things that I'm working on here you've got the galactic core
another shot that I consider believable I tried my old Rokinon lens
didn't think it did too bad I needed to catch this moon with Earth shine oh yeah check this
out yep there's the moon with Earth shine so and then there's the Milky Way
and they are in the same photo this is a this is always a goal of mine that if I
catch the moon low enough on the horizon the Milky Way can absolutely be in the
photo unfortunately for us the lunar eclipse I won't be able to do the same thing because it'll be
astronomical Twilight and the moon will be falling fast so I don't know because it may be around
as it processes it's going to be on the other it'll be closer to Orion I believe but
you're gonna say something Scott go ahead no I just um you know to see that kind of range in
the shot you know all the way from the Milky Way down to uh you know the
illuminated Side of the Moon uh and some Earth shine that's that's
you know it's great to see all of that um you know one of the things that I
know also about the Milky Way and the Moon is if you're in areas if you
actually can get up in altitude high enough to where there's less water vapor you can still see the moon uh and the
Milky Way at the same time you know I've seen that yeah yep when I was at black Mesa I noticed
the streak of the the band of the Milky Way going across even though the moon was at it was a quarter moon and it was
or approaching quarter moon and it was pretty bright it's very dry out there you know so that's right when I was at
um uh when I was on Mauna Kea you know you're up to almost 14 000 feet and just
to be able to not even using having to be dark adapted at all you know just
look up to see the Milky Way like that and to see the moon out right up you know almost overhead it was uh it's it's
really spectacular yeah absolutely look at this shot yeah
all of these are composite shots as I've begun to learn how to process for the sky now that with this
lens I get this effect this is part of the reason I use my other lens for most of my Imaging it it does great here but
if there's some sort of thing that goes on where the the Stars over on the right hand side
get stretched but you know from here to here you know it does great and you know
doing the where you take a shot for the ground and you take a shot through the
sky gives you the opportunity to take a longer exposure
and you don't have to have your camera stretch the image as much so there are a
lot of um nightscape instead are saying 1600 is the magic uh
spot for taking you know these images you know as far as ISO I've begun using
that and I find that the darker your skies the more forgiving
you know your ISO setting can be however it does get to a point where
you're you know you're still stretching things out and I will demonstrate that
in only 30 seconds in a dark side you know I get this that's cool look at
that and artistic there's nothing wrong with doing anything artistic and the
clouds come you don't have to put away your gear and uh that's which is why I like that
shot now I took this core shot and turned out pretty well
you can see the um you can see the color of the trees the
Mesa everything looks pretty good here I go ahead and I over exposed the Milky
Way over camp and I get this this uh this does exist you know these
hydrogen Alpha regions are shooting out of the Milky Way the beginning of the
rofiyuki complex but boy that I blast everything out
you know everything else this whole you know the large Sagittarius starcloud is
gone em8 is gone you know everything is just super bright
but again this might be what you know then here's the here's the deal
if you're doing Astro photography you might take a few of these frames a few
of the frames where you're not exposing as much in a few you know a few other
frames and you may combine them to try and get a final image where you've still got this but you've
got a more you've got more detail in the Milky Way and you've you know you it isn't so blown out a lot
of reasons that these blown out Milky Way images where you just try and reduce
highlights the best you can because there's the cat's paw in The Lobster Claw again
and there are certain features you see in the Milky Way as you um
as you over blow it but you know again this is this is
another interpretation I wouldn't say it was wrong there if there are certain things that you're trying to do
then um there's nothing wrong at all and here is if I can find it because I
took let's see that says October an image that I took in
acceptancy the image I took when I got back from um
Oaky tax and I'm looking forward if I don't find it
I'll punt on my um I'll punt on my attempt
but uh I thought it was here somewhere but what I wanted to show
is sometimes an understated shot can also be effective as well and I found it
so this was so this is an attempt to get the lake um you know back in the oh yeah
to see the Milky Way Shine On The Lake though it's really cool yeah you do and and here I am lamenting because I'm
thinking well these are some life polluted Skies the color may not have
quite been this bright But Here I Go
I say all right I want to image everything here color wise is spot on
including the Milky Way but notice the dust Lane disappears and makes
it looked like you know your Milky Way is basically two parts and it's starting
the dust Lane starting to blend in with the rest of the sky when
you're shooting and you are in a dark area
that doesn't happen and here here's an example in the dark sky the
dust Lane is prominent and you see it and it does not blend into the sky at
all it's darker than the rest of the sky as you expose for this and um
that's that's what I learned from these two shots
here you have a very realistic shot and you you're looking at you know what the
foliage from that Vantage Point looking back at the lake this is exactly
what the um sky looks like and the Milky Way has been
exposed so that it's brighter in the sky here but and then there's more stars
than you would see naked eye it's dark enough that you wouldn't see
this natural color of the trees but that's that's half that's absolutely the
natural color so um I think I'm run I think I'm close on
time Scott have I gone is it time for the if it's time for the
next uh presentation uh Nico was supposed to come on but I don't think he's with us
tonight so I've got often yeah a little bit more we can go a little bit longer
yeah I can go a little bit more I'm gonna share okay my screen and show as
much as I can a bit of processing here let's
here we have you know what I put this in a contest and try to win probably not
but here we have a 129 Second shot
at ISO 3200 um would I shoot the same shot at ISO
1600 and play around with it maybe under
darker skies I find that with a Canon 6D the 3200 seems to do pretty well here we
have the shot for the ground so let's see if in a few minutes we can
make a composite here we'll go to develop and we'll go to my process I came up
with a preset that turns this to mostly
the way that the sky should look we'll go
and we'll do that here now normally what you would also do is
do a profile correction and then see if you like the profile
correction it really brightens everything up look where look where that's at
right it's really bright and if I enable profile correction here
so we do the same things to both and
so what we can do now I go ahead and I take the both to photoshop
to layer them together do some um processing on bringing out the DSO a
little bit more and when that's done bring it back here to finish editing
so here you know this uh selecting the sky
this process has been changing over the time over time
but um I've tried it and we're gonna see if the computer will
work so it's selected the sky I go to select and I inverse and I now have a
sharper ground copy that and then all I have to do is come over here and hit paste
and now I have to figure out if I can set this and this is hard because I have
power lines and everything here so it becomes a little harder to match
I can go so let's play around let's see what happens if I zoom in
if I zoom in again let's see if we can
let's see if we can get this closer whoops let's see
so part of the painstaking part of the process is to
try and match and we're gonna go with that I'm going
to fit on screen as you can see there is a little bit of
shadowing is this perfect no but now the rocks are Sharp
the um you've got detail here what I go ahead and I do is I just flatten the image now
what most seasoned images would do is leave this as a smart object so that I
could play around with it I can dive in and clean up the edges and make this
a lot cleaner but for the sake of just showing process I'm just gonna do
we're gonna flatten the image here then I go ahead I run this enhanced DSO
and reduce Stars this is a process that I love to run because it makes the Milky
Way stand out a little bit more doesn't don't know if it needs to stand out this much that's the thing with a portal one
sky the Milky Way stands out so much that um
you know you see it as you're still an astronomic you're still a nautical twilight heading to astronomical
Twilight and um you don't have to um
you don't have to squint to see it or ask anybody is that the Milky Way it
shows up and says ta-da um it's harder to see in different
portal zones but it's still you know the the darker disguise the
better and that's that's something that I'm gonna go ahead and stop sharing while this is doing its thing and that's
something that I think we as any Astro Imager
has to deal with if we're if we're Imaging the sky and we're
trying to do something like I have on my screen where that part of the Milky Way is almost
centered over the bridge um if Milky Way moves on the composition
for my shot is gone so just stacking thousands of images so that I can pull
out detail you know it's it becomes difficult to
try and figure out the two which is why I just prefer I prefer getting enough detail to where
you can see the Milky Way and then making my tweaks so that in the end I end up showing a little
more than what I saw with my Naked Eyes now it's dark when it's dark I can't see
all this but the camera can and it's there and I also
look to um any color corrections I want to do
I'll try and do them once I get into back in the Lightroom so
so that's part of how the process goes once I once I get that done there's
masking you just saw that the Adobe products allow you to mask the sky and
the ground separately and it figures it out for you whereas you used to have to select it yourself and carefully map it
in or do it you can do a sky replacement that way as well
and that's something I've tried the sky replacement I haven't been able to line
it up quite as well as if I do a ground replacement and as you saw the ground replacement wasn't the best but
it was close which for purposes this demonstration is close enough
but that's composite images allow for more and I believe that the
term is dynamic range Scott for each part like that's how I did the moon
image I did I think I did three um I did a shot on the moon I did a
shot on you know for the landscape and then a shop for tracking
the Milky Way and I put both of the all three of those combined them
um and you ended up with the Crescent Moon which is what our eyes see our eyes can see all of that and if
the Milky Way right you just described it you can see the moon you can still see the Milky Way for the camera you
have to shoot camera is a much more limited range yeah that's true our our eyes I call it context switching
um our eyes can see you'll see the moon then you'll see the Milky Way and you'll
you know the night sky you see it fast enough that it looks like you're seeing everything at the same time if you think
about it though you actually are context switching you're going there's the Moon there's the Milky Way if you focus on
the Milky Way and you avert your vision toward the Moon it will be blurry
um then when you as soon as you look at the Moon it instantly shifts into Focus it's it's very fast and then you know
your eyes can move can change so quickly on whatever you're building up images as
you're looking anyways so it's yeah it's very interesting that whole uh the way that our eyesight works and the way our
brain reacts to it and how we think that we're seeing the field of view you know so yeah our our brain puts it together
it puts it together we're mostly everything all the time yep everything appears sharp yep all around yeah but
yeah try it some time if you're looking at something bright and then you're looking at something much darker like if
you go out in the sky and you see the Moon try looking just away from the Moon and
avert your Vision back to the moon and you'll notice how blurry look right at
the moon and you'll notice how instantaneous it's sharp it's uh
it's a gift of eyesight I call it yes that's right that's right
um real quick Let's uh
let's see what this uh experiment looks like I am going to make stars smaller which
is a feature I love to do and that what that does although I don't
know that I need to make stars smaller here um tends to pop the Milky Way out more
so so here we are we've we're going to send this back into
Lightroom we're going to click on this and we're not going to save changes to the ground layer and
um so we're gonna go into Lightroom um
where'd it go and it should pop up and there it goes
so this one's fun because there was so much red light here that
um you know there's there's a lot of playing around that
could be done to try and correct that and this is what it's like
to use curves to try yeah you see the colors are starting to come in
and make things a little more natural
and after this we'll we'll turn it over
let's see what happens if I move the blue
I I find that stacking colors like this seems to be
the way to do it and I'm taking highlights down on everything
and now even this reddish is a little less pronounced you're seeing some Milky
Way detail so much red you can always
try and lower it by
taking a little bit of the saturation out but you have to be careful because uh
you know if there's some red in here too so what do you do masking tool
select sky and it just detects it and it actually
works around the poles too amazing which is this is these are some new
features that subscribers to Lightroom have look it's it's gone around the pole I'm going to invert
and then I'm going to do things like trap saturation a bit
and raise the Shadows
like that red light I could try things like this
and now that you know a little more of an actual color in some parts I could
try changing the tint
but the you know the red there there isn't much you can do when the red lights decided they wanted to blast that
area there's you can try changing the hue
oh it's purple now uh it's weird weird green you know
this is actually the Natural State the uh the red light is actually the Natural
State so that's what makes it difficult um
you can even you can denoise it if you want I use a tool topaz to denoise and
this is only affecting this area maybe I'd prefer to sharpen it a bit
course I usually use things like texture
and clarity so
it's the way it is we create a new mask select sky this is pretty bright but now
if we can fix that he can take that down yep we started taking down highlights
and now you've got some you've got a little more of the Milky Way showing up Shadows
balances it more and then this is you're playing with sliders and they do say be careful
with how much you play with sliders because
um you can overdo it a lot of milk like
that yeah the histogram sits over in this region and
so now if you want to bring now the Milky Way is popping a little
more and
we've darkened the sky now here's the part that I always struggle
with this was
done 130 seconds which is about two minutes ISO 3200
shouldn't be too bad for dark sky you can see M11 here you can see
m17 M16 and this sharpless object here M8
and I would have to zoom in to see even more yeah now this is really
looking interesting yeah and and that's this is where
this is where you go okay now I'm yeah that suddenly
the suddenly the image changed yeah and this
map now it gets arranged you can't see with the naked eye so much right you
know yep and then there's so much more now you can see these dust Lanes naked
eye oh sure yeah but not not to this vividness yeah not to that vividness at
all so at this at this point you're like okay I've got
I've got something that's close here so I'll get out of masking now I can
this spot if this spot annoys you just clean it up
there it's another spot too I'm gonna leave it there for now and so now you have okay is the sky this
color and you can play around with the whole thing
if you want to the real the key I think is using curves
and there's there's just different things you can do now I've heard someone say never move those points but
maybe we like the way that the sky looks when we move those points
and this is this is an example I haven't haven't shown this image before because
it's an example of when you have data that you're not sure what to do with
you know then you you may run into well how do I present it
and you know you can continue to do things to
try okay yes like that's too red but you can move
and I think we get a little closer
there you go yeah and yeah you can see how you can tweak
but with these kinds of things for yeah a long time basically yeah and yeah we
will be sitting here all night like all night and people do you know and people this
is exactly that's okay that's that is the uh that's the prerogative of the
photographer and uh absolutely you know and you know uh when you're looking as
deeply into the images as you do Adrian you know you're seeing you know nebulae
star clusters you know this feature that feature
um and then and then you look at the whole image from a compositionally yeah and uh
you know you're trying to make the image sing and um
and you do that you do that again and again exactly yeah even if I come back and go you know
oh yeah desaturating it is such a good idea I'm just gonna let that red
and then now you know now I have a bit more of a natural look because everything that had a red light on it
has the right color but everything that didn't is now in the right color too so it's like I'm leaving it there
and you know you look at the sky and say is there anything more you can do
probably not yeah I could sure you know you could try you
could you know do things with contrast or all right
well thank you Adrian that's about it and so you've seen you've kind of you've seen kind of how
the mad scientist does his uh processing
excellent excellent yeah and also why I'm doing
longer exposures at you know lower
I'm doing longer exposures at lower um isos because I want to stretch the image
I don't necessarily need the camera to do it
um and I'm learning that you know with that processing so you know using the
processing software letting the camera or letting the
processing software stretch the image you know it's something that we're learning from the classic astrophotographers it's a better idea
but we want it to stretch some because we're not going to stack a lot of images
if we want you know composition so there's a couple of different challenges in what we've called landscape
astrophotography and we try to meet them all head-on yeah but um so there you go
I'll put thank you very much Adrian okay so we are going uh we've got Caesar
back with us at this point and uh he's uh I think he's done a little bit of
image processing of his own so yes uh hi Adrian your your uh pictures are
wonderful wonderful well tonight I I don't have the alduki
but uh yes uh we can process especially within uh try to process let me share
it's green and I show you let me
I think that much better after before
share let me check um
opening sorry that kind of opening
okay now I can foreign
well they are not so good because the scene was really strong
let me check and share the screen
okay but
interesting thing is the shadow of IO
here uh-huh but of course that is but look at
you got the red spot um yes and some was impossible to make
something better but yeah but yeah the red and spoke you can see their rabbits
pot and the shadow of IO iOS in this
area yes and here you can see the shadow and it was interesting that in the
between the first let me check if I have another one
um let me check
if I have
maybe have another one
okay
capitals uh okay let me check if I have this
thank you um here I have the Moon
but something that I was searching was the
another one of of uh of who Peter with the difference of the position of the
Shadow right but now I show you the
the view of of the Moon uh with some details but no more it was
impossible to make something more than this but maybe here do you have maybe
you can see a very small small characters that maybe are three three
hundred meters crackers um these were well it's it's a uh it's
not as a fully retired a picture of the Moon because in the if if
we go to the rooftop of the building we have a last thing that in the in the you
know in the in the ground where do you have between the buildings
the the turbulence was very very high but well okay what's an experience of
planetary image uh not so good but something enough to show to the to them
no it's it's not it's so bad yes no yes
it's a lot of detail sometimes sometimes yes this area of the
off is really small and sometimes something clinging something like this
and the shadows and it's so magic that are incredible that we can talk
about this something that sometimes say okay this is not good image you know but
sometimes we lost the the scale that we are watching or right making when only
when we was we was Childs we only watch
this kind of pictures in in uh in the
books uh now is something that we can make in the live image and make a small
process to have more details um this is something that how to change
how the times has changed that's it's incredible
um with the Milky Way of of uh Adrian or another of pictures of Molly with a big
Tails Maxi Maxi today was oh my god well
we all saw some amazing images but it's still very nice to see you know you got
us live images of the moon as well a very highly magnified it was cool uh you
pulled off a nice image of Jupiter um you know and uh showed us the red
spot uh all fresh data you know so it's very cool yes some right something like
like that that where um I maybe have another picture but but
when we start to to make the video we saw the we saw the the shadowing apart
um if you maybe half hour you can see the Shelby in another part of the planet and
we are talking about the shadow of a society tile come on think only in a
books the pictures of Jupiter in the books of the 70s
and if you are all right lucky because with a huge telescope there is
the the the draw of the of the
um of the planets was very good but not the
the picture the picture was horrible and now I saw I I I give
I give uh to to Nico a camera
simony camera the same camera that I use it tonight was
trying trying with the with the with his uh dobsonian 10 10 ninjas telescope I
don't know if you saw in the picture of who Peter that Nico took with the same
camera that I used tonight I think it's fully fully of details he is
yeah it was it was great it all has to do yeah
it's the seeing conditions that uh that we all face and so
um you know uh you get great seeing uh those details pop in you know absolutely
my idea is try between uh tomorrow or next Tuesday to to have
some something better um share and compare about the thing you
know um our theme is telling me that they say okay I'm interested in make some
planetary image okay but we are go we need to go to the rooftop to have a much
better uh conditions uh because the problem is the local tournaments here
because the all that that we lost in details it was about the planet was
between two buildings and you have a mix between fresh air or they are from from
the day in the welding expelling the hot air
because it's it's early in the in the night and the it's another cold night of
course and do you have the local Reliance all times I remember that I I
brought the first manual in the in the 90s for for my customers
[Music] um a manual for all telescope about
about how to use a telescope oh wow uh yes of course because for for for me it
was a pleasure and talk with I told with a astronomer to to get something about
uh you know some something that of information to me
to write a better user manual for generic telescope
and I remember the local turbulence was something that I brought
one completed page over what a boy
in our places of observations and chimneys and buildings uh well tonight I
have all completely yes something like somebody making a barbecue and
you can see that yes the moon uh Dancing Yeah well come on
yes I was with without finder two but yes I found yeah but you pulled it up
this group hairs yeah sometimes yes you need to yes you need with no finder and
you're putting it onto that little chip yeah that's better than me that is difficult to find her yes yes that's
your skill in using a telescope right there absolutely um yeah Agustin told me how we can we
can point to who Peter because you have two two thousand millimeters of foreign
okay I can point I can point I I pointed I hope it a little minutes after the
tour with you right for me I thought what was impossible to to to point but
sometimes you need to to to believe
something that maybe you you found it again or or a new Adrian when you return
to the the star part is a real subparities in the field and sometimes
not all that you have uh have a great function like you expect
maybe you for example I I forget something I miss something of my
equipment and in the last time you can make something to to work all things and
enjoy the night and this is something okay maybe for example you you I I miss
the part to put my my my finder but if if you remember in your telescope that
you have to scrub heads that are aligning with the Optics yeah maybe
maybe many many times do you have something in your your telescope like maybe the Vixen bar or something that
you can found the object uh and you you
can get something to to continuing watching or making something of
photography and this is the magic of our our activity where we are thinking okay I
can resolve this problem and it's like maybe I have some resources and that I
can use right sometimes it's Plan B sometimes it's plan c
e f g h d h yeah as long as you keep trying as long as you absolutely
absolutely absolutely right yes yes well that's great
Caesar thank you very much Adrian thank you very much I think this is a wrap for
the 105th Global Star Party we'll be back next Tuesday for the 106th Global
star party and um uh we want to thank uh all of our presenters here we had uh
um we had a Full Slate here we had uh David Levy on for our
um you know for our introduction uh we had um
uh we we had uh of course uh Chuck Allen
from the astronomical League um uh presenting uh you know the questions for the astronomical League uh
David eicher with his meteorites part two um we want to thank vachik from space
shop 42 uh for his uh astronomy Outreach
presentation in Armenia Caesar of course you know uh who's on with us now but on
earlier as well Maxi Polaris with his astrophotography to the Max
and Molly Wakeling showing us uh you know amazing views the cygnus region and
all of that Marcelo Souza who is very happy with the latest presidential
return in Brazil and you know her perhaps a new lease on
on science in Brazil as well Adrian Bradley and his incredible
nightscapes and of course the only one missing was Nico who
couldn't make it probably due to again you know his uh rehearsals that he's got
going on he is a uh you know engaged musician and talented astrophotographer
so after being at starmus I could understand why you know the this
connection between music and the Stars absolutely yes but uh and we want to
thank last but not least our incredible audience watching from around the world
thank you for uh being on with us as well and commenting as you go along and
uh we'll be back uh soon uh we have uh
uh presentations coming up with a new program that we call Eclipse experience
and you're going to see um uh you know some amazing uh
presenters uh that are involved with the total eclipse coming up in 2024.
um you know I do want to make uh you know a little shout out for us we are already selling eclipse glasses and
stuff so you've got to get ready do not do not do this at the last minute uh so
many people did in 2017. people done yes
your get your books on the eclipses find out where you need to be you know
there's incredible eclipse of books that are out there this one is from Great American Eclipse with uh uh Michael
backich and Michael zeiler and they cover you know uh southern hemisphere to
Northern Hemisphere here with incredibly detailed maps so here's an equal oh we
do have Nico [Laughter] Nico how are you man
is he coming on yes he's trying to we are expecting that
yeah yes it's like my internet in in the near to the pool of the world there he
is [Laughter]
I'm sorry I'm late but I really miss you guys and I want to be here just for a
minute to say hi and and see how are you doing yeah we're all good we're all good
you know I'm glad you're here because you get to take over from me
it's a rest with Nico now that you are here the hammer
I was talking about your your amazing picture of of Hope Peter because I I I
showed the my picture and say no Nico have the the wood one I I was uh
watching the show in myself on what I was driving at my home so I I listened
to you okay well thank you for popping in now I'm
really happy to to be here sorry I'm late but the this this is complicated
for my other activities but uh understood I I want to to be here
for a few minutes to show you my my last words let me share my screen
are you seen yes yes okay well uh in in the past month I I may make a little
upgrade in my setup with my 10 inch dobsonian but I get a camera as Cesar
said and SB money a 305 and it's
really really great to work with a color camera because with my dog cyan I am
moving the the setup and and I lost a lot of frames and with my monogrammatic
camera I cannot make a good integration of the image
so these past weeks I was working and how to improve my my captures
and I found uh with the color camera integrating maybe 15 minutes of videos
and I found a way with the filter will to separate the sensor of the Barlow
Lane and increase the magnification but uh
I think the results speak for themselves this is a Saturn
wow look at that yeah
it was a really big difference and I'm really happy with the results you can
see well I made this composition with the the moons but the the small details
of this camera are is is amazing and I'm really happy with this camera
excellent and this is the same camera that Caesar loaned to you I guess is that right yes yes I I stole this camera
from season and and it's it's really great because
uh as I say I'm working with a dobsonian and before I was working with a
monochromatic camera so I need to make four videos for only one color image and
this one was 10 videos of 90 seconds integrated so I won a lot of time for
the camera and this camera has a pixel size of uh I think 2.9 microns so
it got a better small details than the qhy that was I was using before
and the last picture I I make I'm so happy with this picture of Jupiter that
oh yeah as I was talking about it's dramatic it's really beautiful yes
because the the night it wasn't the best thing but for a moments
even in the eyepiece you can see the Saturn that there was a really really
sharp details and in this name particular I started a
shooting before he Transit because we have a Callisto around
and I could get this uh
this first look of Calista with some small shallow or something but
it's really it's really amazing to to get this kind of images
with a dobsonian cat tracking at home and the camera Works amazing
and um came to our rooftop
um we need to practice it with you yes we have we have a pending sessions
to to say yes yes and try different equipments with the
camera find the right uh the rate I I
found that no matter what camera you are using but
you need to make some calculations to find the right uh focal distance
to to get the best results with the pixel size and this camera is not uh for example
with the qhy5 that has a 3.75 microns
you need to maybe use an F20 to get
these kind of details smaller and with this camera I was working at F 30 13
and it works great and I am making this week's uh
a little Improvement I found a way to Place models in the dobsonian I am
working with a guy that is making for me the uh a go-to system for as the sea Moodle
and making some pieces on really so I maybe in in the in the next week or
the other I can start shooting with the tracking so that will be a new word for
me right right see what's happening well it's remarkable and and a beautiful
image and uh so congratulations Nico thank you Scott
um well I I was seeing a lot of pictures and histories of the of your traveling
because I I wasn't here the last weekend congratulations it was a lot of travel
in a short amount of travel a lot of people and it was it's really were
really nice to to see you in showing that uh so someday we will do that in
some other place of the world yeah and uh Nico I want to thank you too you uh put together a uh very nice program for
the starmus astrophotography class and uh so they they really enjoyed that and
got a lot of information good information out of that so thank you okay thank you cut
great okay well thanks for popping in it's a nice surprise so we're we're uh
we're batting a thousand here we got all of our presenters uh that we thought we'd get today and yeah and um so again
uh we want to say thank the audience and we'll be back next Tuesday for the 106th
Global Star Party hope you all come back thank you very much good night everyone
good night so

Transcript for Part B:

foreign
that name probably you probably saw it
as a byline you know in the magazine
once in a while so Ray shubinsky's wife
is is a teacher and her name is Carol
okay and for the first time they all
went and the four of them went into the
British museum they're wandering through
all this stuff everything in and out
blah blah blah they go into the Elgin
marbles gallery
okay you know which are the
you know the the marble pieces
dismantled when you have an army it's
easy to put together a good collection
you know yeah and just take it you know
from from the Parthenon you know and the
Acropolis
and so Carol stops looks you know it's a
big long rectangular Gallery both ways
with a and she said oh those kind of
marbles
[Laughter]
she's a little bit of a wonderful sweet
but kind of naive lady okay so that
really happened she that's the Carol
shabinski Elgin marbles story yeah it
sounds like a Gracie Allen uh
response exactly exactly yeah so she's
probably heard that a thousand times in
the last 30 years played back to her
that story exactly raciality exactly
yeah perfect
I need to check something guys uh let's
see
hello everyone
um my name is
participate okay to this event uh all
right for recording it's too late
thank you
the perseverance Rover is filling up two
hey Scott yeah another quick
interjection just of business if I can I
hope that I'll get this ready maybe for
next week
um okay because I've kind of you know
could show minerals until you know the
cows come home but we've we've gone
through all the really good stuff for
the most part there that's well
organized I've started to put together a
list with a couple of really detailed
star atlases that are interesting to
look through after some years of what
I'm calling oddballs of the cosmos okay
very interesting strange objects I like
that uh throughout the sky and I thought
maybe I'd start doing just talking about
one of each of those each week oh yeah
and there's uh you know there's a list
of like you know there's like a thousand
of these we could talk about so so what
what do you think of that idea I love it
I love it you know Celestial cartography
is uh you know I think all of us that
are into astronomy love star maps and
and uh
these are maps right well I'm I'm using
the maps to put the list together but I
would really be talking about the both
the astrophysics and then the
observational aspects of these weird a
lot of them faint objects sure
does that sound appealing enough sounds
appealing okay okay and when we're
talking about business I've got I've got
a little business task as well is it
okay if I plug my new book this
afternoon oh absolutely thank you
absolutely I need to get a
photo of the cover and then I can make a
little commercial thing out of it so
okay I'm very happy to do that I'll send
you one
David what is it
it is uh Clipper Cosmos and children
finding the Eureka moment nice
and there's congratulations
excellent with original artwork by Joan
Allen Rosenthal
David thank you sure that's fantastic
news yeah thank you David yeah who did
the artwork David Joan Allen Rosenthal
my sister-in-law actually oh okay okay
great
but there's
um
just all kinds of art nice
and
um
how long did it take her to do all that
well over well over a year almost two
years wow
[Music]
let's see
astronomical League
okay all right we are
we're ready to start with our
Little David I gotta tell you
much as I enjoyed your presentation last
week I'm glad to see you looking like my
friend David this time you know that was
the most ridiculous thing I think I've
ever done
and I was the thing that haunted me was
not the character I was figuring I'd do
something ridiculous for Halloween but
Terry Mann said when you speak
