Transcript:
7:00 p.m..John Briggs - History of Adaptive Optics - Introduction of Dr. Fugate
i'll throw in the ladder if you guys buy 65-inch telescopes i'll throw in a ladder for you
7:15 p.m..Dr. Robert Q. Fugate - How Laser Guide Star Adaptive Optics Happened and Astrophotography in the City
you think that would be a good sales pitch includes free ladder you buy the scope we give you the ladder all the
ladders yes i like it your ladder to the stars it's
7:30 p.m..Daniel Higgins Astroworld TV & Shawn Nielsen - Visible Dark
it's that's right it's writes itself that's right absolutely mark that let me i'll be back
and i'm talking i need to call my lawyer yes stairway to the stars
we might have to yeah i mean robert never get copyright infringement for that jimmy page might demand a look through
7:45 p.m..Adrian Bradley - Star Scapes
the scope now it's that other band that had that
copyright suit against him for stairway to heaven yeah was it called spirit or something like
8:00 p.m..Lisa Ann Fanning - RASC
that they didn't have it against them it was i can't remember anyways the fights it was against led
zeppelin for stealing the chord progression
8:20 p.m..Ten Minute Break
who was the rapper who stole the the baseline uh from under pressure remember that queen
8:30 p.m..Jason Guenzel - The Vast Reaches
got a big payoff for that i don't know yeah that was vanilla nice
yeah vanilla ice yeah he had to cough up a few millions to queen as if they needed more money yeah right
8:45 p.m..Marcelo Souza - Sky’s Up Astronomy Outreach
yeah i'm sure vanilla ice needed the millions though you know so
yeah i think you're cool so vanilla is expensive you have to scrape it off a tree bark
9:00 p.m..Cesar Brollo - Star Party Valle Grande 2022
that's right you did all the coin he could get who was the first guy who discovered that if we scrape this
paste off of this bark it's really yummy
9:15 p.m..Maxi Falieres - Astrophotography to the Max
these are the things i wonder about this is why i never got into any of the really good schools these thoughts oh
yeah i think you got into a very good school day now while we can thank you debbie
where did you graduate from david i went to miami university the the old it was
established believe it or not by george washington in southwestern ohio it finally got
going in 1809 and it was a little school that was like a high school
until the 1830s and expanded where my uh father taught for many years chemistry
but not in 1890 much later on yeah when john i i want to give you tell
you why your school was so good they years ago used to have a telescope
at that school yes it was a beautiful 12 years alvin clark refracted yes and
at one point they decided they didn't need it anymore yeah and uh guess who they donated it to
leslie c peltier yes yep they gave it to him can you imagine that what a
connection called on the line and they said would you like we'd love to donate to you a 12-inch refractor
yeah alvin clarkland said boy was he excited oh you imagine getting a call like that
with observatory and transit room and thankfully leslie actually did some
really really great stuff with probably not too much happened when it was in oxford that tell us probably not yeah
but uh leslie did a wonderful wonderful thing for him yep and he likes to describe how he how that
telescope and his six inch uh refractor would talk to each other after he went to bed
and uh the refractor would say the 12-inch would say i can see 16th magnitude stars
and the 600 would say yeah but you can't catch a comic [Laughter]
nice very nice hello chuck it's good to see you
chuck both davids how are you doing good yourself good to see you
how goes the league tonight everything in order it continues to teach me
a great lesson in life and that is that uh the secret to life is moving from one
failure to another without losing enthusiasm i'm wrong
no they'll deliver philly's doing great we've got a delay on the website uh it's
aggravating us a little bit and uh we're hoping in the next couple of weeks
two weeks maximum we'll be able to review it and get it going that's good good yeah boy is it hard to find
developers these days well we found a good developer but we're trying to merge the store with the
website and we have a lot of databases award databases membership databases and uh
getting all that incorporated has has had some
difficulties associated with it so tricky business yeah
it sounds like things are getting close though they're very close
good this particular quilt from neil degrasse
tyson is pretty poetic in itself you know it may be that our cosmic curiosity
is a genetically encoded force that we illuminate when we look up and
wonder i like that i like it it's a little touchy feely but but then again you know
you think of the earliest hominids who we'd derive from were around uh about
six to seven million years ago clearly you know they looked up and saw the moon and things like that and must
have thought in some way you know what is that and you know as brains got bigger you know
creatures were we tend to think of past generations long ago as fundamentally
stupid but they're they weren't you know a lot of our ancestors they were reasonably
smart but they lacked technology and experience you have to think that for
many countless generations our forebears looked up and wondered what these things were you know and so there's
there's some truth in geneticism and encoding there i think from this
right what i like is from jill tarter we all of us are what happens
when a primordial mixture of hydrogen and helium evolves for so long that it begins to ask where it came from
nice thank you that's great now jill tarter will be at starmos won't
she she will indeed yeah she is on our board wow so you will meet her
that's very cool she's wonderful she's really really wonderful and you know her perennial sidekick seth showstack
yeah he's a funny he's one of the great guys he's funny yeah you have to get him on
global star party pretty i'm sure he'd love to yeah yeah he's been on global star party once before
yo he's a brilliant guy and of course jill is is a genius yeah
wonderful well i guess we're ready to get started folks here we go
[Music] scientists used supercomputer simulations to throw eight different
types of stars at a monster black hole their goal is to create more realistic
models of tidal disruption events which occur when unlucky stars stray too close
to black holes gravitational forces create intense tides that deform the stars and break
them into streams of gas these simulations are the first to combine the physical effects of
einstein's general theory of relativity and virtual stars with realistic internal structures
this schematic shows the star's trajectory in this version of the simulations the
black hole has one million times the sun's mass and the stars are about 24 million miles
away at their closest the model stars range from about 1 tenth
to ten times the sun's mass the colors reflect their densities
from the lowest shown in blue to the highest in yellow [Music]
in some cases the stars are fully pulled apart in others
they're only partially disrupted as these stars move farther from the
black hole their own gravity pulls them back together surprisingly the stars that fully and
partially disrupt aren't cleanly divided by mass the sun-like star along with those with
0.15 0.3 and 0.7 solar masses survive their close encounters
but stars with 0.4 0.5 3 and 10 times the sun's mass are completely torn apart
the difference between survival and destruction depends on the star's internal density
simulations like these will help astronomers build a better picture of these catastrophic events
occurring in galaxies millions of light years away

[Music]
well hello everyone and a big howdy out to our audience out there around the world uh it's great to have you guys
logging in and checking us out we have an incredible lineup for the 90th global
star party uh starting with uh david levy we'll move on to chuck allen from the
astronomical league we've got david eicher
editor-in-chief of astronomy magazine with more minerals and crystals of planet earth we've got john briggs who's
going to introduce and talk about the history of adaptive optics but he's going to introduce dr
robert q fugate and he is the father of
laser laser pointed artificial
stars i guess for working on large aperture telescopes for
adaptive optics so it's uh pretty exciting and these uh when i understand an incredible
astrophotographer as well um daniel higgins from master world tv and
sean nielsen from visible dark will be on together it's awesome we've got adrian bradley
and someone new also lisa ann fanning from the royal astronomical society of
canada the halifax center she'll be on jason ginzel the vast reaches uh rejoins us of course
marcelo souza will be there with us to talk about sky's up magazine and what's going on with his uh
new event that's coming up here in a few days cesar joins us back again and he's going to be
talking about the star party valley grande 2022 so that's pretty cool and of
course maxie fellaries with astrophotography to the max so we'll get started now with your
friend in mind david levy david well thank you thank you scott and
it's good to really good to be here and especially to talk about the cosmic
flow that that is our theme for this week and uh for a poem
to introduce cosmic flow i was thinking back to shakespeare
and um i wanted to ask how many of you have seen the omega
centauri star cluster i think a lot of you have dave it has just about everyone on the
zoom session has and i'll bet you a lot of you facebook and other people
uh listeners and watchers have seen it as well rick hill called it oh my god centauri
it is a beautiful cluster and it's probably the most beautiful globular cluster in the sky
it is so beautiful and shaped like a lovely oval that some people say it's not a globular cluster
at all but the remnants of an external galaxy that interacted with the milky way
somehow but we really don't know for my quotation today
i go back to william shakespeare and he wrote julius caesar and as he was sitting down
in his um in his uh study writing the final words
they find that uh brutus has been killed and he writes his famous this was the
noblest roman of them all speech and after he's done he closes his
book he goes outside and he sets up his explore scientific
telescope and he takes it and he looks up at omega centauri
and which is a bit of a tough bird to try to find from the logic of london so he sails a little bit further
south so that he can see it and then after he sees it with his explore scientific reflector
he writes these words this was the noblest star cluster of
them all all the star clusters save only he did what they did in envy of this great
cluster only in a general honest thought and common good to all made one of them
his life was gentle and the elements so mixed in him that nature might stand up
and say to all the world this is a star cluster thank you and back to you scotty thank
you so much yeah absolutely you know the first time i saw omega centauri i mean
it's it's it's almost a heart stopper you know you just can't believe
that your amateur telescope can be flooded with stars like that you know and it's just uh
it's spectacular and it takes it takes a while to after the initial shock of seeing this thing if it's your first
time to kind of let it absorb in you know and you just go wow and then it's just uh
it's there's a tranquility and a beauty of it especially if you've got a real wide field eyepiece you know
uh you've got this concentration of stars and it's spreading across
and it's just uh it's just it's a great place just to kind of
stay on sort of hover in you know and uh and to just uh wonder at the amazing uh
illumination of all of that so thank you so much david thank you thank you
yep okay so um
up next is uh chuck allen chuck has been with the astronomical league for
uh decades and has supported them in so many different ways and so many different roles
but the role that i i always finally remember him is is the when he was
president of the astronomical league and uh we um got to talk about and share our
enthusiasm for supporting young astronomers uh you know and the astronomical league uh
i think that is one of the organizations that does it best they recognize them they they nurture them uh
and uh you know we have uh been uh honored to uh you know do what we can uh to help
support that a little bit but it really is the strength and the venerability of the league
that has helped encourage young people to you know change to
inspire them to to learn more you know to become scientifically more literate some of them have gone on to be
through their exposure and their recognition from the astronomically have you know taking up uh
studies and astrophysics and i think it has better their lives so and
in so doing you know i think it makes the world just a little bit better every time if they do that
uh of course i'm speaking about the national young astronomers award and uh
chuck can can tell the story better than i can but i've been honored to um participate in
all that i also want you know i every time i want to give a nice shout out for the astronomical league they are a
constantly growing organization over 300 uh clubs in their federation over 20 000
members and you know all the individual clubs that make all of that
up uh really make a powerhouse organization when you think of all that together so
chuck thanks very much for coming back on to global star party well i think that's my line scott
you're inviting us to be a part of this for these last several years has been a great benefit to us
30 years ago when i came up with this national young astronomer work program it was scott who
jumped in one year later and started providing amazing telescope process to our winners and he's still
doing it now three decades later and has made this program really sale so uh
deepest appreciation to to scott for all you've done for us over the years thank you it's been an honor
let me share a screen here
one thing when young people get involved in astronomy we like to make sure that they protect their vision
and mistakes can be made especially when you're starting out in astronomy at a very young age
and some of those mistakes can be result in permanent eye damage if you're not careful observing the sun can be
done safely but you need to be very careful about certain things i won't touch on all of these but
certainly never observe the sun without professionally made solar filters that include energy rejection filters that go
at the front end of the telescope not the eyepiece end you don't want to use a solar filter or
welder's glass that attaches to the eyepiece for example because heat can build up in that eyepiece in that filter
and burst it don't leave a telescope or binoculars unattended where other young people
might try to acquire the sun and i have actually seen someone try to do that
be very careful about using eclipse glasses make sure they're certified or from a reliable source the astronomical
league can help you with that and never use eclipse glasses for anything other than direct viewing
through the glasses only don't use them with binoculars or a telescope i think scott did an experiment with
some eclipse glasses by placing them over an eyepiece through which the sun was shining and they melted almost
immediately so be careful consult local amateur astronomers and you can do this safely
but you have to learn how first we'd like to first of all cover the answers from a week ago from april 5th
and here were the questions which four letter word beginning with the n is a star showing a sudden large increase in
brightness then gradually returning to its original state over a period of weeks to years the answer is nova
and the second question from a week ago whoops wrong way
titania miranda and bianca are all moons of which planet in our solar system and the answer of course uranus
and the third question from last week in space or astronomy the big bang machine
is another name for what and the answer is the large hadron collider
all right the correct answers from last week are these eight individuals
and i will let you just read the names these names will be added to the door prize list at the end of the month
okay these are the questions for tonight please send your answers to secretary at
astroleague.org secretary astrology.org that email address appears at the bottom of each
slide i'd like to start off by the first question by showing you
uh a image from an edmond scientific catalog in 1969.
um quite a bit before 1969 my first telescope when i was seven years old was
a three inch admin reflector just like this and i used 20 and 12 inch telescopes now
but some of my greatest memories were first views through this and one night in october of 1956
uh i was trying to observe a number of objects and tried to observe a certain galaxy that was very large on
the charts in fact it was huge on the star charts and for some reason i just could not see
it and i was very frustrated by this i went to bed and i just stood in bed i'm eight
years old why couldn't i see such a large galaxy in the sky so i
my bed was right up against the window on the second floor we didn't have air conditioning in those days so i raised
the window and scooted out on my back so that my neck was on the sill and i took a pair of
binoculars and looked straight up at the fall constellation where this thing was and boom there it was a thumbprint
smudge very obvious in binoculars and it was then in october of 1956 that i learned about surface brightness and how
it relates to what you can observe and that object is pictured here and so our first question tonight is
this is the second closest spiral galaxy to the milky way identified by one of its two popular
names or one of its two catalog designations again the email address is down below
whoops sorry now this object on the surface of mars was discovered by christian huygens in
1659 and it was the first surface feature ever detected on mars for many
years it was thought to be a plane of some sort it measures about 930 miles
vertically about 620 miles wide and it extends north from mars equator
the mars uh global surveyor however determined that this was not a plane but
actually a shield volcano with a very gentle slope of about one degree on average
so what you're seeing here is dark basaltic rock from a shield volcano on mars very large
shield volcano and so the question is what is the name of this conspicuous dark
area originally thought to have been a plane now known to be a shield volcano
at the center of this image of mars
okay finally former planet pluto was the subject of
considerable controversy back in 2006 when the international astronomical union
uh decided that it was no longer a planet in a vote that was taken during their convention i believe in prague that year
they established three criteria for a planet one that had orbit the sun and two be massive enough to collect itself
into a spherical shape which pluto qualified for in both cases
but it was found that the third criteria the ability of a planet to clear its orbit of other
objects that pluto failed this test because of other tnos
in its region and the neptune itself so the international astronomical union
is the world organization of professional astronomers and question number three is what is the u.s organization of
professional astronomers called
okay and again answers to secretary at astrology.org
please join us on april 15th at 7 pm for yet another event that scott so
generously hosts for us and that is the astronomical league live event uh we have john weskowitz weskovitch who
will be talking to us about lagrangian points and the james webb telescope it will explain to you how an object can
orbit absolutely nothing in space and so we look forward to seeing you
then and scott thank you very much i will return it back over to you
very nice thank you very much yes it's uh it is a little bit hard i think for
people to get their heads wrapped around um the lagrange point too so
uh i would join that group but it's amazing that we were able to
figure it out and i look forward to hearing hearing his talk during astronomical
league live so that's going to be great we have uh we we will turn
our gaze from the sky back towards earth uh with
our our good friend david eicher he is the editor-in-chief of astronomy magazine he
is an incredible rockhound um as well and uh someone that understands
the uh you know the universe not only through the lens of a telescope but
through the lens of crystals and minerals i like the way i said that last time so i'm just going to say it again okay so
anyways david eicher thank you for coming back on to global star party and sharing your minerals and crystals with
us thank you scott thanks for having me and i will see if i can
share my screen and while we were sitting here
over the last few minutes maxie um sent us a beautiful image can you see
my screen yeah a beautiful image of omega centauri and
let me add let me share it with you it can you see the cluster and i will just add very briefly to what
david beautifully said and that is that we do now know that
omega centauri is the defunct nucleus of a dwarf galaxy that encountered the milky way
gravitationally it's and now is the largest and most massive globular
cluster in the milky way it has a a mass of about four million uh sons um
so lots of stars there and as anyone you guys i think i've done it probably with scott and with david and maybe with some
others here literally we were down at the texas star party looking at this together and in
one of those big dobs like scott makes so nicely you can see this cluster and
it's almost as if you're orbiting this thing it's such a beautiful sight so you definitely want to try to see omega
centauri at some point if if you can and now i will stop
sharing and i will try to share a different screen oh dear there we go yes now let's see if
this works and now we'll come back to earth and i will see if i can start
a slide show and you'll either be delighted or horrified by the fact that we haven't
gotten through all the minerals yet but we're working our way through there's some element of randomness here
as well because tonight i'm going to talk about aluminum and barium minerals and sometimes the groups of images that
i have together without getting into a resorting of hundreds and hundreds of
images kind of represent what's on a display shelf together so that's that's the only thing that's going on here
really between aluminum and barium but we'll look at some common minerals of the many
many kinds of of both that are principally made up of of those important elements
as we talk about all each time the universe is ordered uh thomas jefferson
said i believe in a divinely ordered universe long before jefferson's time isaac
newton one of the principal founders of modern science uh gave us the quotation
truth is ever to be found in the simplicity and not in the multiplicity and confusion of things
and the universe is ordered not by supernatural design
as our pal richard dawkins likes to say the universe doesn't need to be magicked
into explanation but by the principles of physics which in an ordered way show
us what's really happening minerals demonstrate this because their atoms are assembled in precise ways by
electrochemical attractions inherent properties of the atoms that make them up and guide them in into assembling in
what mineralogists call a crystal lattice that brings these crystals together
when they get disordered ground up moved around and you know lost and
and pulverized is when they turn into rocks and other stuff like that but the
universe likes to make things in an ordered way and that's what minerals show us
so we can talk for one thing about aluminum minerals a little bit tonight uh of the many many many kinds of
aluminum-related minerals corundum is an important one because it's well known by
a couple of other names and it's a simple one too it's aluminum oxide it was named
coronvindum in 1725 by john woodward and derived from the sanskrit
kruvinda which is the word for ruby richard kerwin used the current spelling
corundum by 1794. it was known by many names in antiquity adamant sapphire ruby
hyacinthos hysteria and so on it comes in many colors colorless blue red pink yellow gray
golden brown and others it's the aluminum dominant analog of several other minerals the common one of
which is hematite iron oxide and the red variety of this which is
colored by contamination of chromium atoms is ruby and the blue contaminated
version of this which is uh contains iron and titanium atoms um is called sapphire and those are very well known
of course because they're super hard minerals and they're good they're pretty and they're good for making jewelry
the crystallography of corundum is trigonal and of course it has aluminum
and oxygen atoms in this kind of a lattice that come together and and crystals are made like
this whenever the material is available in the right way at the right temperatures and at the right pressures
and the right abundances usually in hydrothermal fluids that will
flow in rock and accumulate these atoms and make crystals but not always
barium is another important mineralogical producer the com most common barium mineral is barite which is
i'm using the official which is the english spelling here with hawaii because the international mineralogical
association not giving away any clue uh for chuck's quiz here this is mineralogist
um spell it they they accept the y spelling it it's spelled in the united states ite though uh it was named in
1800 by dietrich carson from a greek word for heavy because of its unusual
weight for a non-metallic mineral it's very heavy holding a you know a small size
even partial hand size sample of barite you can feel how heavy this stuff is it
comes in a lot of colors as well including colorless but white yellow brown gray blue and so on it's typically
found as a thick to thin tabular crystal usually in groups or clusters with
crystals that grow parallel to each other and also as bladed masses
as well so it's a very common mineral too barite crystallography it's orthorhombic
and and you can see it's a crystal shape with with barium with sulfur yellow and
oxygen atoms as well involved in those crystals
so again as always here are just a few examples of what some of these things look like from a typical uh struggling
editor's collection here's a a corundum this is a variety of corundum we would
call ruby although it's almost transitional here between ruby and sapphire with this kind of purpley pink
red here this is a madagascar specimen that also has a lot of mica biotite in it as
well this black stuff and this shows you kind of the natural way that ruby crystals often are found
in nature before they are cut of course by jewelers which horrifies mineral collectors because we want to show the
minerals as they are naturally here's a small ruby but a very nice
colored ruby specimen from vietnam this was one of the first minerals that i got in the modern era
after my father contaminated my mind with interest in this among many other things remember
collectors you can never turn back you can only collect more whether it be books or you know observations of the
sky or minerals or what have you so you got to be committed because you'll never go back
here's another uh example of a ruby this is also with black biotite and you can
see little tiny almandine uh sort of honey colored crystals those are little
members of the garnet group in there as well this is a russian specimen from a very well known locality
there now we get into some different aluminum minerals this is called wavelite and i
threw this in there for scott this is a aluminum phosphate hydroxide hydrated
and this is from a very well-known area of quarry in montgomery county arkansas
all right the best locality in the west western world for wave of light which is
an unusual uh phosphate good stuff that said a lime green color
this is a turquoise which is a copper aluminum phosphate hydroxide also very
popular of course for jewelry this comes from a famous old gold mining town where there was so much turquoise around
they didn't worry about it and in the old days even when i was a kid you could go out to creek and when there
was a rainstorm in the streets of creek colorado you could see the
little blue green bits of turquoise flowing down in the in the little areas
around the roads there's so much turquoise there so this is a little piece of turquoise
from creek here's an unusual one let aluminum
phosphate hydroxide hydrate some of these mineral combinations are a little bit of a mouthful this is a chinese
specimen of what's called plumbo gummite which is an interesting aluminum
phosphate that gives you this sort of very nice dark blue color
brazilianite is the glassy yellowish crystal a sort of lemon yellow crystal
here it's a sodium aluminum phosphate hydroxide this is from a well-known area
of minus gerace brazil which is the state in brazil which literally means the
general mines there's so much mineralogy that comes from that region brazilianite named after the country of
course here here's an odd one that's an unusual mineral potassium aluminum phosphate
hydroxide hydrate that's a chilean specimen called tinsleyite that gives you a very you see there's some very
basic elements that are involved that are similar in many of these and different little contaminants are
creating these very vivid colors in some of these minerals
this is an illinois specimen of benstenite which is a barium calcium
magnesium carbonate also with some gypsum here whitish gypsum from a famous region that's really well
known for its uh fluorite but this is another similar mineral that's in there as well in illinois
kyanite is a fairly common and simple but a pretty mineral it's an aluminum silicate this blue stuff blades of it
here this is another from that area of brazil that's a fairly chunky specimen with
quartz in it as well and this is that common mineral of
barium barite this is a big piece of it here from the michael mine
in nevada that's a famous united states mine for barium minerals and this is a big piece it's it's a sort
of a table top piece here with these kind of glassy lemon colored crystals here's another one
that's a little bit different a sort of a sky blue colorado barite from another
famous and barium mineral location in up in the
mountains in colorado all golight is another unusual
aluminum mineral and it produces some of the recent fines of it from peru give you these sort of very vivid
lime green crystals of this stuff which is pretty cool with a lot of quartz there as well
this is an unusual mineral it's an aluminum fluoride mineral durango
which is an odd one it's a fairly small piece here from utah and it just shows you that sort of vivid orange red color
here here's back to barite this is a recently there have been very good finds in china
of barite this is on quartz but a very vividly colored barite crystals here that are
very glassy looking uh here's barite but from back to colorado here from a famous another
famous mineral town gilman in colorado here
this is a very odd mineral it's organic meaning that it is
principally composed of oxygen and hydrogen bonds not that it's
you know extra expensive fancy strawberries and blueberries in a special case
but organic chemistry means that it's it's carbon um dominant and and contains carbon
oxygen hydrogen bonds this is mellite and you can see it's dipyramidal
uh crystal structure here and and this is an aluminum benzene hexa
carboxylate hydrate so that it's a very long i'm sperry i'm not putting the formula in here this
would be a long one but this is a hungarian specimen and one
of a relatively small number of minerals that are so-called truly organic minerals sorry scott i didn't mean to
did you say something yeah i just said that was a mouthful yeah yeah yeah yeah that's a very
unusual you know you don't hear that one very often no it's a kyboc
hexa carboxylate yeah yeah and start using that in conversation so i'll try that tomorrow
again when i get some more sleep i hope tonight
that's a weird one but you can see in their little crystals that are dipyramidal that formed as the fluid
presumably ran out on the on the surface of the larger crystal too so you can see these
generations of crystals sometimes that form in uh in proximity
and the last one here is just a sort of a stark white barite on on
hard stone-like mud that comes from of all places muddy creek
appropriately named rio grande county colorado and that just sort of gives you
a variety again of of kind of a typical aluminum and barium minerals and just
very quickly again scott and i will pipe in on we're both going to be
involved at starmus in armenia in september which is the international
science festival in which we'll have many astronomers astronauts you can see them there
and nobel prize-winning speakers in other allied scientific fields like chemistry and biology we'll be
announcing many many more speakers over the coming weeks i already secretly know of some but we can't quite announce them
publicly yet our star must folks will be doing that soon and we'll also have some rock and roll and other entertainment
there with some of our good friends uh like queens brian may rick wakeman and
peter gabriel and others so that will be a great great time it's actually very easy if you get to europe it's very easy
to get to armenia from there and cheap so consider that or
maybe you'll see the after um uh effects of all of that uh uh later in
the fall as well we hope had to have a lot of stuff and exciting things to to share with you and scott
is going to bring over telescopes and put on a gigantic star party for the
starmis attendees we think there'll be three to five thousand people at starmus and maybe a thousand people at our star
party so it's gonna keep us busy scott that's gonna be busy yeah
i hate to get bored so i have a question yes uh david
uh i was looking through a kind of an interesting list last night called the most valuable
substances in the world and antimatter was at the top of the list at
62.5 trillion dollars per gram number six on the list at three hundred
thousand dollars per gram was a mineral called painite a bore a crystal
uh have you have you ever run across that anywhere yeah the crystal of painite in my collection
which i paid thousand dollars per gram i paid vastly less than three hundred
thousand dollars for for my crystal i can tell you but i can i can get the image of my painite and show it next
time next week please take a note for that it is a rare mineral and it's an
unusual looking crystal um and it's often accompanied by little very bright
uh purplish and orange garnets that go along with it so i'll show it next time
and we'll talk about what it is mineralogically i'll dig that one out um and it is a rare mineral and it's
somewhat valuable but i had no idea it was that way maybe we should have gone public with
the fact that you haven't there are people now breaking into your home david too
if it's that valuable let's sell it and we'll go have a party you know with the telescopes
i think i'll figure out what you can do with that 300 000 david
sounds good well thank you scott as always and at some point through more minerals and i'll get back
to some more uh straight astronomy one of these no yeah i don't know i think you're teaching us that uh
the study of minerals and crystals is part of the straight astronomy so well we have to have something to do
during the daytime that's right yeah that's right absolutely
okay well thank you so much david that was awesome up next is um
is john briggs john is uh uh known by many in uh
not only in the amateur astronomy world but also the professional astronomy world and he is um
uh he's with us tonight and he will be introducing uh uh i think he's with us tonight
let me just check here hey scott i'm here but i uh
okay my video and i'm getting up getting something i haven't seen before that blue comment can you see that
i do see it yeah yeah it's it's uh saying that you have a v cam um what i'll be on here with you so that
people can actually watch a moving figure but uh but uh uh john thanks for coming on uh
and thank you for um uh introducing um
uh dr fugate uh to our audience and
you had mentioned before that you showed some of his images but through you i learned that
about dr fugate's work in adaptive optics so maybe you can
explain absolutely now i had a few slides i wanted to share but i'm um i i'm i
haven't i don't understand why i'm not sharing my video um
i think you can share your slides oh okay you don't have video okay so i'll
share screen and let's see uh share
yay okay and i'll try to make it big and all this stuff
from beginning there okay can you see that yes
very good it's going up it's it's still a gray all gray box but um
the title is introducing dr robert q fugate founding director of the united
states air force optical range uh let's see your screen
sharing is paused um i think i might have to redo this so i'm gonna stop share okay and i'm
gonna share screen again and sorry that i am uh bad at this
no problem do you see a picture now uh we do yes oh good good
great okay so let's let's see if i can make it advance from the wilds of uh new mexico
here and it did not it seems that i always have this problem
there okay um i am i i want to explain
uh how i got acquainted with dr few gate and it relates to this um
photograph that i am so proud to have from my own backyard
and uh bob fugate recorded this picture from my backyard
and uh what happened was i subscribed to the albuquerque astronomical society email list
and one day a few years ago there was a message there from a fellow and it said well i'm up here in
albuquerque and i've done about all i can really
accomplish with my current equipment from the bright skies of the city and
i'm looking for a darker sight where i can go deeper with my astrophotography
is there anybody out there who could recommend a site and it was signed robert fugate i saw that and i thought
holy mackerel i'm gonna reply to this very promptly because i knew who bob
fugate was and um to explain uh i'll i'll continue
uh but bob ended up coming to my uh backyard and i have i've shown you some
of his pictures before and i have to admit when he came um i felt like a kid
interested in rock and roll but having somebody like the rolling
stones come and practice my garage that's how i felt about having right
astronomer bob fugate but anyway how it happened that i uh had that attitude
towards uh bob was that earlier i had worked at yerkes observatory here with
the 40-inch refractor and the very first project that i engaged in
was to create a uh sodium star in the upper atmosphere as shown here
with a sodium laser shining parallel to the 40 inch refractor that's in the left
hand side with the refractor pointed towards zenith the right hand side here
is a of a ccd image that we recorded through the 40 inch
showing a a blob in the upper left that was actually the sodium so-called sodium
star in the upper atmosphere and the light saber to the lower right with some
rayleigh scattering from the laser beam going way up about 90 kilometers to create that blob so so we were
undertaking this experiment in very early 1991
to understand how to how to make a a blob of that
like this in the upper atmosphere given whatever laser power we had available this was
interesting because it was related to this new science of adaptive optics and
the person that i was working with in this small team was a fellow named
walter wilde and he was a became a great friend of mine and
it within a few years after our experiment which which was just a small stepping stone
in adaptive optics at university of chicago this article came out co-authored by bob
fugate and my friend walter wilde it was in sky and telescope magazine
in a let's see it was the may issue of 94
untwinkling the stars part one and uh this article actually it was a series of
articles in over two issues in sky and telescope that involved 19 editorial pages to
cover this topic when it finally came out it was a big splash and bob fugate
was the first author and and and further uh part of this splash was a
biographical article about bob with text and photographs by the famous and
excellent photographer roger restmeyer and i just encouraging people who want
to learn more about the revolutionary topic of adaptive optics to look back to
these articles and sky and telescope back in 1994. they are great and uh but
perhaps the coolest thing was how in the first of the two issues there's bob
fugate on the cover um beside the gigantic telescope we do in fact have
here now right at the air force base outside of albuquerque new mexico adaptive optics
straightening starlight but how it began
bob had uh smaller tall scopes a meter and a half tall scope here projecting a bright
laser beam and early experiments related to all this
i've never explained some of the details for you but roger's photographs are just so
spectacular i could not resist reproducing some of them from these magazine articles but the quotation from
fugate who's with us now is let me just read it in the movie jaws there's a scene with
two guys in a boat the shark comes up out of the water and he's wider than their boat fugate recalls
one man turns to the other and says we're going to need a bigger boat and that's how i felt in 1987
when i went into director pete avanos's office and said sir we're going
to need a bigger telescope and he threw me out on my ear but i just kept going back unquote
first persistence hard work and the 1.5 meters results paid off for fugate and the air
force eventually approved the 3.5 meter tallest project
and here it is and bob will have to tell us is that actually he
uh climbing the ladder there on the left-hand side for uh some human scale
on this uh amazing telescope that is here in new mexico uh doing quite uh
fantastic things the article that i'm referring to um is a great reference to learning more about
uh the technicalities of ao and there's also a book that's been published the adaptive optics revolution
a history it this technology truly is folks a revolution for ground-based astronomy
and it was written by this air force historian robert dufner now is as nice
as the title pages it's actually the dust cover of the book that i think is
especially cool there it is again adaptive optics or revolution a history
who's on the cover bob fugate as a young young man
with i presume his first telescope and bob you're gonna have to tell us is that is that a little criterion reflector
looks like a three-inch criterium reflector to me so there's a there's a very tasty introduction to bob fugate uh
who i'm so grateful to call a friend here in new mexico so i'm gonna
stifle myself and i hope that bob can take over and continue the discussion
okay can can everybody hear me yes yes let's uh yes okay um
well gee whiz um john is always really good at embarrassing people especially me
yes so i i don't know this is a hard act to follow
let me uh let me try let me see if i can share my screen here and
uh get the uh presentation started
and i wanted to give a first of all that was in fact me on the
uh on the telescope and um what else did you ask yeah that was a
three and a half inch refractor i think the very one that was shown earlier in in a catalog
so it's uh it's a small world uh any rate i have a lot of material
here too much um i'll see if i can get through it um this is just a collage of
how how laser guide star adaptive optics has evolved and um over the years
and let me see if i can hide this um
so it all started in 19 when we did the very first experiment in 1983 and i'll
talk a little bit more about that and that moved to a one and a half meter
telescope as john mentioned [Music] and then to the three and a half meter
and these first two uh experiments were done with rayleigh guide stars
created by rayleigh scattering in the air and uh hang on just a sec
and so it's evolved and it's actually become the enabling technology that
makes these very large telescopes uh practical and and feasible
and uh so we expect with the extremely large telescopes coming up in
in this coming decade that this will be a very important
if not essential ingredient in the operation so let me tell you how this really happened and
came about so i i started working for the air force
in 1970 and it was the height of the cold war
the soviet union were launching satellites every two or three days the u.s was desperate to know what they were
about a lot of them had military applications
and so the air force built a telescope in cloudcroft new mexico a 48 inch
and the observer if you can see here actually rode on the telescope
and you know they were they were recounting on the i brain neural network
to see to help the distortion caused by turbulence but um
mostly what they got was a lot of blurry images and why was that so i'm going to
give a quick explanation if you have a telescope in space and it has perfect
optics you have essentially a diffraction limited telescope here's an example of
the trapezium imaged by hubble but if you're on the ground
here comes your nice plane wave traveling through the vacuum of space for 12 billion years
and in the last millisecond of its journey it has to go through the atmosphere and gets totally screwed up
phase wise so it becomes a crinkled mess and you get this blob and
now the resolution of your telescope is limited by the atmosphere
and in particular by a parameter called are not the freed parameter and that's typically at a really good
site 15 or 20 centimeters so if you have a telescope that's bigger than that you don't get any bigger
resolution you get the same blurry image that you get in a smaller telescope
you just get that blurry image faster but
what if we had a magic mirror and by that i mean what if i knew what the instantaneous
distortion of the wave front was and i could put that shape or its or
actually its conjugate or the inverse of that on the surface of the mirror almost
instantaneously so that when the distorted wave front reflects off the mirror that distortion gets removed
and i'm i'm back to my plane wave that i had when i entered the atmosphere
well this is the basis of adaptive optics and it was originally suggested by an astronomer horace babcock
in 1954 but it wasn't until 20 years later that we had enough
technology to actually implement it and so we put our magic mirror behind the
you know in the reduced optical space of the telescope and we sample part of the wave front
with a sensor shown as item number two here and that runs up and
and controls the surface of our deformable mirror this magic mirror that we're talking about
and so the the first of these uh in operation at least for
you know anything real was built under the sponsorship of what was arpa
at the time now darpa by the company itac installed on the 1.6
meter telescope on maui and it was a
tour de force i mean it was still very difficult piece of equipment
this is a big operation i don't know if my cursor shows very well but here is
take a look at the size of a person standing on the floor of the observatory here
the problem with this instrument was yes it worked on bright targets but it didn't work on fainter targets and a lot
of the satellites that the air force was interested in looking at were pretty faint
so one of the people sort of involved with the project julius feinle was standing on the ground one night and he
and he noticed the lidar going out to measure atmospheric transmittance
and he got the idea that maybe you could use a laser to create a beacon that could be
sensed for the turbulence um independent of the target
so you would use the laser to you know do atmospheric wavefront
sensing and then you could integrate as long as you need it on a faint target
so he actually called a meeting in
the fall of 1981 i was at the meeting and david freed the kind of the free
world's expert on turbulence was there and initially he said it wouldn't work
because it was too low not measuring enough but he did some analysis and what he determined was
the idea would work but only for small apertures it needed to be higher and and it was going to be too difficult
the air gets too thin for rayleigh scattering for that to work well by chance the group called the
jasons asked to review this project they got word of it and uh
so in the early summer of 1982 uh will happer from princeton chaired a
committee it had people on it like freeman dyson so i and david freed went to brief these
folks and will hamper said so your problem is you
can't get the beacon high enough and david freed said yes and
will said well why don't you resonantly excite mesospheric sodium it's at 90 kilometers
so david and i looked at each other we didn't know what the hell he was talking about
uh but you know that's how we we now had and so this so it turns out there's this layer of
sodium atoms that are about 90 kilometers above the surface of the earth that are deposited by micro meteors
and sodium is light the meteor burns up the sodium is light it sort of hangs out it
has nothing else to react with so now we have two concepts
um one that used rayleigh scattering shown on the left
the idea being that you know this could only go to a certain altitude maybe 15 or 20 kilometers
because of the air density on the right though we could get up to 90 kilometers if we could excite these sodium atoms
so we have the two concepts and um darpa
immediately classified the concepts and they also sponsored two experiments
and the objectives of the experiments were you know they wanted an experiment for each concept could you sense
turbulence with back scattered laser light was that even possible and the second was do these results
agree with freed's theory he had a theory about the fact that the beacon is only at a finite altitude
and not at infinity so if you're using it to measure light that comes down in a cone instead of a
cylinder you're going to make an error and he had and we called that focus and
isoplanetism and he had a theory about how well it would work so i immediately volunteered to do the
rayleigh experiment because i had no idea i was going to build a sodium laser that was powerful enough to work
and lincoln laboratory mit lincoln laboratory unfortunately got stuck with a harder experiment and it took them an
extra year or a year and a half to get the results so here's the only picture because this
exp because this whole concept was classified and limited access and
there were probably 50 people in the country knew we were doing this
we the idea was that uh we pointed a pulse laser at polaris we didn't have a gimbal
telescope we only had a gambled flat and the idea was to compare the light
back scattered from the laser in a range gate and only at a certain range
um with the light coming from polaris and when we and you know all of the
setup and we had sort of a shack hartman arrangement
with made out of risley prisms and a 40 centimeter off-axis parabola on the
bench to make a telescope and so here's a couple of the measurements here's on the left you see
a wavefront reconstructed from polaris and on the right away front reconstructed from the laser
and in the middle at the top you see the difference and the question was does that agree with freed's theory
and here's a plot showing two sets of experimental data and the dashed line being freed's theory
so this was an incredibly important chart because uh it basically verified that
we understood the theory about how this would work and later lincoln laboratory did the
experiment with a sodium laser and demonstrated uh even further how it depended on range
we we demonstrated how it depended on aperture diameter and and they demonstrated the range part
so eventually this technology this was 1983 and in 1991 eight years later it was
declassified mostly because of the demise of the soviet union
and we immediately published the results in nature
and that even created some
some uh humor by the editors of nature and if you know anything about nature you know they're not very jovial
they're serious dead serious all the time and uh so
what they they published a little editorial in the in the issue where this article was published and it was
entitled beam me up scotty so this is a picture of the one and a half meter which we
got a copper vapor laser installed on so it ran at a high enough rep rate that we
could close a loop continuously with a real deformable mirror the other the initial experiment was all
open loop measurements and so we were able to do initially some science with uh with that setup and one
of the first things we looked at was the trapezium and we looked at it in with a h alpha
filter and a continuum filter and so here you can see the difference and
this this shows the formation of these uh polypropylenes uh you know new stars
forming that are not yet emitting in the continuum so we we offered the telescope to the
national science foundation and we had a regular parade of astronomers coming through
uh using the system but while this was going on
i you know john's quote there was perfect because i went into pete avazonos the day after we
installed the meter and a half telescope and said we're going to need a bigger telescope and that's when i got thrown
out but we um we kept going back and eventually
we built a three and a half meter it was based on uh spun cast borosilicate mirrors by
roger angel at the university of arizona and uh that telescope um
got installed in the early 1990s and we even had a collapsing
dome because uh we were mostly interested in tracking satellites
and they go over fast and the telescope has to go around fast and we couldn't move a dome with a slit
so we decided just not to have a slit and we just lowered the dome
and this worked out incredibly well so we got the adaptive optics working um
in by 1997 our budget had been slashed a lot in the in the 90s
but we finally got through it and by february of 98 we had it tuned up pretty well here's an example image
this is a um this is a .098 arc second separation
binary star and having a stroke ratio of about a half at 0.8 microns
and a comparison of the open loop and closed loop image
so it was very successful in looking at satellites and uh but it wasn't until
uh 2004 that we had um you know solved the problem of how to
build a sodium guide star that was practical uh the pro you know problem is
sodium vapor can't lace it has too short of a lifetime uh you can never get a population
inversion going in a vapor and uh so it turns out that
our first laser was built by mixing in a non-linear crystal the two ir wavelengths the strongest
lines of neodymium yag 1064 and 1319
and that comes out perfectly at 0.589 and um so that's what we use to
build the guide star and it was all done in-house at the air force research lab
so it's been used to look at faint objects uh one one of
the one of the things the air force is always interested in is um looking at uh geo uh geosynchronous
satellites and making sure that high value assets aren't being approached by
nefarious objects and so you have the problem of a bright object relatively
speaking and a very faint object and so one of the things that we've looked at are uh asteroid moons
and here's an example uh we also still have the meter and a half and now we have a modern solid
state frequency double jag laser on this telescope and here's
a picture it almost looks um here's looking down the throat if you will
the three and a half is on the right and on the left is a seeing monitor
that is used to measure the the scene this almost looks like
a graphical package produced but it is a real photograph
and um we have at maui now at amos where they for that very first system
operated there is a 3.6 meter telescope and you know they they beat us out by a
tenth of a meter so they can claim the rights of having the biggest air force telescope or the biggest telescope in
dod i guess and so they have a guide star on that system
as well and in the middle of the picture in the background here you see the noa solar
telescope there on on maui so today
all large astronomical telescopes have laser guide
stars and in fact people uh don't even think about
you know all the new extremely large telescopes basically uh have
uh adaptive optics laser guide stars built into their design
and this is the eight meter uh one of the eight meter vlt telescopes in chile
and um the astronomers have advanced this art quite a lot and uh using multiple guide
stars and multiple deformable mirrors in order to increase the
corrected field normally you're limited by the isoplanetic angle but if you use
a asterism of guide stars and multiple mirrors this picture at gemini south for
instance where they have five laser guide stars has a two arcminute field and is well
corrected over that whole field oh yeah um so
let's see what's happened here i'm going the wrong way oh
so where this is leading of course is the new telescopes uh
um the two biggest being the 30 meter and the 39 meter telescope being built uh
now and of course there is still some contention about the 30 meter telescope
on mauna kea but um we're hoping that gets worked out
and uh they're they're working away on the um 39 meter
european extremely large telescope uh in chile
so um i'm 17 minutes in let me see if i can tell you a little bit about
if i'm if i'm getting too long just cut me off i'm going to switch to now the famous
fugate observatory which is in the backyard of my house in albuquerque new mexico
and the thing that makes this famous is the mount is on loan from john briggs
so uh i would not be where i am today without it yeah yeah
it's really uh i'm seriously indebted to john because one of the things i've
figured out is by using short exposures i can i can run this telescope unguided even
on narrowband images and uh and get 95
of my signal to noise in a shorter exposure so i just really like the idea of not
having to fiddle with a guider i show one on the telescope here but it's rarely rarely used
so just let me you know the imaging strategies i'm using are not new they're not revolutionary they're
they're common and in fact the i'm a little embarrassed to be
showing any images here because they're ordinary and uh but let me just let me just tell you a
little bit about my strategy and that is uh if i'm looking at broadband targets and i do that it just
takes a lot longer and i'll kind of show you why
uh to to reduce the shot noise associated with the sky
your choices are a monochrome camera with broadband filters a one-shot color
camera but in either of those cases you have to average a very large number of images to
get to where you would be if you were at a dark site on the other hand in narrowband a mono
camera with narrowband filters as narrow as you can afford and i'm using three nanometer
filters um that's a really good choice and now of recent we have a technology
that we've actually been using that i used in the air force a long time ago and that is specially
made filters that have multiple lines that are narrow so you can get duo or trio or even quad
line filters now that you can use with a one-shot color camera so you can take advantage of the
bayer filter pattern in the camera and the filters all at once and you're
not being inefficient by using an you know a single line narrow band filter with the one shot color camera
and quite often if you're doing this you'd want to capture separately rgb stars stars are bright compared to the
sky so you can do you know short exposures 30 seconds or less
and get star colors and then add those in take out the take out the monochrome
stars and put in the rgb stars and then of course it still helps to average lots of images
so the one thing i've done is tried to be quantitative and here i show a plot of
[Music] on the left is the photo detected electrons per minute per pixel for my
setup with the takahashi 106 and the zwo
asi 6200 monochrome camera as a function of sky brightness in
magnitudes per square arc second and i have a little uh sky quality meter
which i carry around with me mostly everywhere that i go which isn't very many places these days
and um keep track of what the sky is like and uh
one is easily able to convert uh the sky brightness measurement into
what kind of signal what kind of mean signal you have on a particular setup and in this case
it's mine so here at home i get about a hundred photo detected electrons
per minute per pixel for a g band filter for a one minute exposure well this is
per minute so if i go to the helo and i have some friends that have property there
where where it really is dark i get about 10 electrons here in
albuquerque i get like 100. so what that means is if i were to
sample the pixel values in an image like do a horizontal scan to the to the image
i get these kind of results the bottom down here is a dark frame but then in the gila it had an sqm of
21.95 nice you can see the noise level here in albuquerque the noise level is
quite a lot higher and if the moon is out even in albuquerque it makes a big difference
so our so our problem here is all this noise if we're looking for something that has a small signal value
in a single exposure you're not going to be able to get that so that's why of course we have to average
in order to you know if there is a gradient on this image and let me show you an example here is the witch head
nebula this is an average of 100 one minute frames
and it shows quite clearly the the gradient of light pollution and this blue line is a sample through
the image which is displayed over here um
for instance this little bump here i don't know if you can see this but on the right side this little bump
is the witch's chin and
if i look down at this lower one here at the bottom here i've removed the gradient but i've
also compared it to a single frame and this is an l filter not a
you know one of the color filters so it is a wider spectrum the noise is enormous can i see anything else in
there not really and what i've done between these two is i've removed the gradient but the
important point is i haven't removed the noise so i still have this fuzz this what's ever
left over from averaging 100 frames of the shot noise when i when i subtract the dc gradient i
still have that shot noise so the only way to get rid of that is to average more and more frames
so this of course brings up the question what is the optimum exposure time
i keep clicking the wrong button here sorry um and it really depends upon it starts
to depend upon uh how bright the sky is how bright the target is
and how much read noise you have and also how much dark current you have if that's significant although
these days it's for a cooled astronomical camera it's not very significant
so this just shows um typical read noise values for cmos
cameras the new modern cmos low noise cameras compared to ccd cameras
and it shows a slight slight advantage to the cmos
for achieving you know the ultimate signal to noise in a short sub-exposure time
and you know as you get to a darker site if i were to look at this plot for instance for the gila
this would be much more pronounced i would need much longer exposures at a dark site
so you could say one of the advantages of living in us in a bright sky is you can do shorter exposures
you got to look at the bright side of things right right [Applause]
so then let's talk about narrowband quickly here's two exposures of one minute each
of the flaming star nebula the one on the left is a red filter of 100 nanometers bandwidth the one on the
right is an h alpha filter of three nanometers and so clearly we we see the advantage
of going narrowband in in light pollution because it's greatly increased
the contrast by simply reducing the background and
if i sample these two images along these lines i get this so the black dots are the r filter
and the red dots are the narrow band three nanometer filter
and here i've estimated the noise just as the square root of the mean signal
um you know again assuming poisson statistics for the random
arrival of photons you know i didn't say it but uh this is a spatial sample
of pixels uh which is for these kinds of detectors
where there is such uniformity pixel to pixel it's equivalent to doing a temporal
average of one pixel over a lot of samples
so you can still see a little bit of a kind of a gradient and you can still see the
presence of a signal even in a single frame here but the signal to noise down here is
much higher so um the other
uh aspect and at least half of what you get in an astro image is the
processing so i've been using pix insight for some
time and uh lightroom and i i think
um you know what you do in the processing is
is a whole big super topic and i think following me we're going to have
some people that know a lot more about it than i do um but
one of the things i do do in lightroom that i've found and if there's any secret sauce to any of my imagery
it's using luminosity masks in photoshop to enhance the contrast
of various parts of the image based on their luminosity
and so i can bring up the stuff that's weak and um compared to what's bright and not
affect that um so let me just show you some images
uh i'm already out of time this is a um
the boogeyman nebula barnard's loop and m78 i think everybody probably
recognizes this was 14.98 hours and this is you know this is a broadband image
so if you integrate long enough in the city you can get pretty good
results here's um you know another classic
and this was for only 4.42 hours
and it does have some h alpha enhanced red channel uh here is the witch head nebula
you know that we were looking at earlier and this was 3.67 hours over two nights
here's my last falls andromeda again these these bright these these broadband
targets are bright and uh it's it's going to be hard to do things other than that this was actually
10.3 hours over three nights here's the iris nebula this i just love
this target this thing is really cool uh and you can see lots of uh dark dark
nebula here and this was 18 hours over five nights and it's two panels
and here's the classic um m81 and m82 and uh you can even see
some integrated flux nebula in the in the city of albuquerque in a broadband
image here so it's pretty good and 11.4 hours
uh here's uh orion and um
you know this is just this is just such an incredible target this is uh
a lot of different exposures i should have left all the details on but it's a high dynamic range kind of uh
construction and it's only 2.6 hours though because you know it's so bright
for narrowband targets here's the cygnus loop this is a modified sho
and 20 hours 20.3 hours of total integration here's
the pelican uh nebula this is highly cropped out of the frame
in only one hour here's the inside part of the sole nebula
and it's five hours uh here's the inside of the heart
uh five hours again over three nights and the nice thing about narrowband is
you kind of have an artistic license to modify colors
to make them you know kind of a work of art if you if you're so inclined
um this is lbn 581 and ngc 7822
here's my meager attempt at thor's helmet and
here is the elephant trunk with the stars removed i kind of like it this way
because it really shows a lot of structure in the in the clouds
seven hours of integration and i really like to do
single line monochrome images because it really gives you lots and lots of interesting structure
and here's only two point 2.08 hours on the horse head
and this is m42 but it's with a sulfur only filter
and uh and by the way this is a single 20 minute image
i did use tracking on this one but it's a single 20 minute image and of course
uh orion's right in the middle of the geo belt so in one image i had no way to
get rid of the satellite trails here it's amazing that you can see geo satellites through a three nanometer
filter but you get to see all of these uh
shock fronts and stuff and i want to do more work on
sulfur around this region and here's a three panel um
h alpha uh mosaic four and a half hours one night
and i dug up real quick omega centauri since it was uh the topic earlier and
this was made from the albuquerque astronomical society's observatory
the general nathan twining observatory south of albuquerque
and here is omega centauri in all its glory in the new mexico desert
um here's another uh new mexico desert shot of comet neal wise
and it just so happened that uh this uh t-rex was running for his life at the
time so uh sort of a cretaceous extinction shot
okay so that's all i had i'm sorry i kind of ran over um but um
that's uh that's what i had to show actually bob you you landed almost
exactly on the right time because the next speaker comes up at 7 30 central so you you guys
were in combination doing pretty well that's great um i really
like that you know i i want to to add to my um enthusiasm about uh
uh you know that i might have expressed earlier uh bob in in my emails to you
but uh we are really honored to have you on this program so um well i'm i'm really honored that you
asked and um so thank you very much for the opportunity thank you so much that's
great hey scott yeah can i just ask bob a question real quick please do please do yeah i was
just wondering bob uh it's shawn nielsen here from visible dark um yeah hi sean hi um i was just wondering your exposure
time is it typical that you're doing one minute is that yes short exposure okay and what's what gain and offset are you
using for the camera i'm using the standard one i'm using a gain of 100 and an offset of 50.
okay all right fair enough that's good you got some fantastic images some great results very very high details in it
yeah i have um you know i skipped over a lot of stuff there but um
you know like i mean you know if if you don't have to guide i mean first of all you you have to do the
periodic error correction on the mount and you have to do the polar alignment well
but uh but the paramount me and software i run the whole thing on a raspberry pi
and and i run it from my office over 150 foot ethernet cable that just lays on the ground
and i i have a linux workstation inside that runs k-stars and ecos
and i run that as a server on the raspberry pi which also runs the sky x
which is absolutely required um to run the mount
but it turns out that that the raspberry pi actually runs the sky x
you can you can run the full deal on on the raspberry pi so
and i download 128 megabyte files in a little over two seconds over the
and i get them in real time on my display and on my workstation and
uh they go on a nas server and i can also look at them in detail on another
computer uh in pix insight while it's well the observations going on so
i can keep track of whatever i need to but with the um
with the um good polar alignment with t point that's available in the sky x i make a
mount model and get a good polar alignment and with the periodic error correction curve
installed in the firmware i don't have to do any guiding for
well the the drift rate is about a tenth of an arc second per minute so in 10 minutes it drifts one arc
second which is way less than the seeing right yeah no you have some fabulous images
the details are just just incredible so i i feel honored talking to a famous guy like you
sean famous guy no no that's dan no that's not me man no that's
but you're it famous no not even close man i mean i made my first four dollars on
youtube i think uh the other day so i can't charge william shatner prices
for my autograph so i'm not famous [Laughter] oh well well well i gotta say but but do
you have a william shatner autograph oh dan
i actually got i got two of his autographs i got one on a actual figure so do i i have two
that's a great one that's a good one yeah that's fabulous but i was lucky to meet him on the uh 50th um 50th
anniversary anniversary right yeah that's awesome that's great well that was that was a great presentation bob really enjoyed that thanks for joining
us man those those things are great man what size scope was that again that you
were doing it's a takahashi fsq106 so it's a 106.
wow that's awesome you got some great stuff man then thank you
thank you hopefully hopefully you don't have to give john back his mount you know i don't know what i'm going to do if i
do no i'm not you know it's it's being way too productively exploited
um it's uh it's really i just uh i'm a reflection nebula
uh uh uh shining in bob's uh accomplishments so
um it's really great to see what he can accomplish right from the city that's this can't be overemphasized that these
so many of the images he shared were recorded in uh albuquerque what's the
population in albuquerque bob uh i don't know it's 350 000 or 500 000.
i don't know i haven't kept track yeah well it's probably a half a million in the in the area here in this so an
amazing an amazing thing is wonderful
all right thanks again guys for the opportunity thank you bob i i hope that we can get you back on to one of our
programs i think that we could probably do just a program just on you um with all your experience and
everything i think that our audience will find it fascinating so so uh i'll hit you up for that sometime
all right thank you thank you very much thank you too john all right so um
uh well uh dan and sean it's the dan and sean and sean
we just need some beers you don't have man no no
i'll make sure i'll make sure i make believe you can't see me hold on a second oh no oh
dan where did dan go oh there he is [Laughter] how's it going john it's
going great dan good good it's awesome to be on the show with you man again and you know we've been on each other's
shows over the past year yeah we have you heard absolutely and uh a lot of fun yeah we sort of just bounced things back
and forth with each other from show to show absolutely it's it's great it is yeah it's really good i enjoy the
astroworld show i i try to tune in as much as i can and uh you got a great thing going there dan
yeah really great job and you're as well man i mean i i i've been watching you for years so i
mean you know we only started i guess we started about two years ago in earnest
like two years ago and uh we were on like four years ago me and charlie walsh
and he was like cosmic charlie and declanation dan i remember i remember i had yeah i had
said i saw the one episode where you guys were in the kitchen talking about an eagle if i'm not mistaken yeah
yeah we were doing an eagle and then we were in a basement with a blue couch doing something i think we would have i
think we were talking to chuck iu one day on on on the cell phone we had the cell phone on the table and we were like he
was on speakerphone because you you you didn't have any stuff set up yet this is before
you know but uh before you exploded but uh that's awesome yeah so but you got
you you got some great stuff with the pix insight tutorials and and and your beginners tutorials i still watch i
bought it i watch it and like i i continue to watch it uh because i always
pick up something new every time well that's that's that's the thing right you i like to i like to sort of see what
other uh astrophotographers are doing how they're processing their images because you can pick up little nuggets of
information little techniques tricks things like that that you may not be aware of so
for me it's it's about sharing the knowledge that i have that i've accumulated with regards to image
processing um but i really enjoy watching other astrophotographers like
bob i'd i would love to get bob there back demonstrating his uh luminance
technique there for inside photoshop and in lightroom and that that he uses to bring out details the fainter details
and that it would be really interesting to see how he does that little nuggets of information like that are fantastic
yeah absolutely because you know it's it's everybody knows that like that that that
does the processing of imaging it's it's so subtle
and the things that you do are so little you know basically you see yeah you see it you did too much and
you know it's it's like one of those things that i picked up from you on your youtube channel and you know if
if you're blowing it out you're blowing it out okay go back and do it again because you can watch you can watch the
video over and over and over again and and and it's really really i mean
visible dark in itself uh your website and your your channel is just helped me
out personally immensely i know i talk to you over messenger all the time yeah hey man what's up with this qhy camera
i'm i'm from the u.s i don't know what qhy means [Laughter]
it's uh you know it's it's it's different it's a different type of uh you know different type of camera than
what i'm used to i you know started with an spig well my first real camera was it s big um and
uh you know i i went to i kind of went to zwo and then i kind of veered away i
would i went to the qhy route um so uh and i'm loving it actually tonight i'm
going to be getting first light with the qhy 268. uh it's all set up ready to go yes the
monochrome yeah that's good that's great it's basically the same thing you got set up in your in your background yeah
it's almost identical yeah because we've got we've both got explorer scientific 127 set up and we'll have the qhy 268m
uh connected yeah so yeah almost identical setup so it'll be interesting to see what results you get using yours
uh you've got worse light pollution than i do that's for sure but i'm still doing tonight so
yeah well ha is great yeah definitely if you're in the city in that um and you got light pollution problems narrow band
is the way to go um i i really only get about an 18 or 19 on the sqm meter here
um which is we're in a population of about half a million uh where i am in the city
so it's not uh it's not huge but it's enough that it certainly uh impacts the
skies and uh the quality of the sky so but uh you got to do you got to work with what you got you know right now
with the eagle eye i am at us according to the eagle eye pointing in the north
yeah i'm at a 17.21 so
so uh just pack it in and take up xbox and that's why i mean that's why i do a
lot of nara band and yeah you know because right now we got what uh i guess about a um
75 to 80 moon up right now yeah and you know so but i also have the the red
cat set up i'm going to be testing that with the i access 100 mount tonight um and uh i i
got like this m81 82 project that we're going to be doing but that's awesome yeah well you've gotten some you you
know you've gotten some really good results with uh you know considering your situation there and the uh light
pollution that you're dealing with so fantastic uh stuff that i think that's one of mine yeah i can see that behind
you that's great yeah that's really good yeah that was awesome that was with some help from a friend
is there okay okay yeah so so i got some processing help there uh did i run yeah
i was wrong yeah but uh but you know i was like i i need
to get this gradient out of here man it's crazy because i'm doing rgb and portal eight plus guys it's just
horrible yeah it is yeah yeah well what do you in pixon site where you're using dynamic background extraction normally
for your gradient removal yeah i only use uh dynamic i don't use that's all i use now too i know a lot of people like
the automatic but uh i find the dynamic background extraction works a lot better in yeah i think a lot of people are
scared about it though i think well yeah they don't know how to use it necessarily yeah yeah which is why i
actually put out a video about how to use it a little in depth a little probably a little long for uh for most
people but uh there's there's really no way to explain it any uh
uh in less time basically you know it it but once you pick it up once you learn
how to do dynamic background extraction in pixel sight it isn't that difficult to do actually so yeah yeah
pretty quick the one thing i should i should probably tell everybody about dynamic background one of the things
that people overlook a lot is the background map and they they just say ah i don't need
that and and just go and place blocks all over the place and uh and you're
really gonna do a lot more damage to your photo than what you would really
want um and just take a look at that super stretch it see what see what it looks
like and if if you see if you're doing one shot color and you still see a little bit green in this area or a
little bit blue in this put another sample somewhere you know maybe you have to do a diagonal or a radial or horizontal or
vertical and to get because if you're dealing with nebula you got to get that you got to get that area
you know yeah exactly yeah exactly so what do you got coming up on the show astroworld oh what do i
actually i i just picked up and i'm gonna say it max i'm sorry i'm gonna say it so so
max who's in in on the uh on this show all the time is gonna be a
guest uh in may so uh he's gonna be coming in may and adrian
what are you smiling for you're next so uh [Laughter] putting it together i'm putting together
how i'm gonna follow up all of these excellent images with the uh stuff that i've got because lately i've
probably done a little more birding than i have uh night photography thanks to our cloud
cover but um i've got a couple things uh brewing that i think is gonna work so
we'll cool we'll see how it we'll see how it goes i'm collecting a couple of images right
now and um i'm gonna try and put a slant on it that's going to make it
in the theme of the uh starscapes that i usually share so uh we'll see how we'll see what's uh how
this works nice i know scott loves uh
is also loves birding so i've begun mixing in some of the uh
some of my birding to the um show and
yeah kind of an irreverent after showing night uh photos i end up
showing a little bit of the birding that i also do and i'm gonna kind of combine the two this time
there you go got birds see how it works well there won't be birds in space
they'll be they'll be within our atmosphere probably close to the ground all right
cool but uh closer to the ground than us but um so
is it my turn to go or you have to you have other well if i could just uh really quickly go ahead and um
we got so this wednesday i think it is it's like tomorrow tomorrow um we have charles
bracken coming on uh he's uh he's an author he did uh i'm sure a lot of people know the deep
sky imaging primer he just came out with the deep sky planner the the second
edition uh he's actually going to be going over he put the presentation together of 17 steps of how to improve
your astrophotos so you may want to check that out um after that we got april 29th we got dr gaston about that i
might have messed that up um from innovations foresight and he's going to be going over
i guess a less known way of guiding known as on axis guiding and he's going to be going
over what he has uh at intervention foresight then we got on may 4th we got richard wright from starstone software
formerly of software bisque and on may 13th we have eric coles uh who's an
astrophotographer as well and one of the the main guys over at the astro imaging channel um and he's going to be coming
down and and hanging out with us there so so and and then we got uh
maxi going to come on on the 20th of may he couldn't fit the thing but he's going to be on on the 20th and showing us a
lot of photos and and we'll talk about we haven't even spoke about what we're going to be going over yet but we will
that's great that's good that's a nice lineup that's a nice lineup of gas way to go
um do you mind if i just scott do you mind if i just show a couple images real quick uh hey absolutely okay let me just
have an astrophotographer come on and not show astrophotographs
hey can you see my screen there yeah okay so i i just wanted to show a
couple images um first of all this is the setup that i'm using right now and i'm really really
impressed with the explore scientific the 127. this is the carbon fiber edition um it's been working really
fabulous i've been getting some really good results with it um so there's the 127 i've got my auto guider
underneath and i've got we won't we won't mention this other telescope here we'll just
ignore that one yeah you can mention it that's cool is it okay
explore scientific does underwrite these shows but it's not the explore scientific show so right yeah well
that's that's a william optic 71 that i have there and i use that primarily for for one shot color work um just because
then i don't have to take cameras off the the the main scope and and switch things out so i use that it piggybacks
on top and i don't use it all that much it's really just extra weight but i do use it sometimes so primarily i'm
using the explore scientific right now but this is one image that i took of ngc 2264 that
turned out really nice i think uh using the explore scientific 127 and uh
this was and this is all shot from uh bortle i'm gonna on average i'm about a portal
seven uh it depends what direction i'm facing if i'm looking more towards the city core
um i would be bortle eight um if i'm looking away from it i'd be into portal six maybe but on
average i'm about portal seven sky so this is um this is a
an lrgb uh with h alpha image that i took of ngc 2264.
and this one here i'm really happy with actually uh ngc 1333
um again this was shot from you know fairly light polluted area and
uh it is not using any narrow band this is all uh this is all lrgb heavy on the luminance
a lot of luminance data went into this i can't remember i think there's about 14 hours of data
for this image and the majority of it is luminance the color data is only about maybe three hours of
that but it turned out really well and it captured a lot of the dark dust and and so forth and a lot of great detail and
colors within the uh the nebula region the reflection nebula and the mission nebulas and whatnot so really happy with
that uh that image and the the quality of both the telescope um and also the
camera the qhy 268m has been a really great camera i've had a really good success uh using it so
um and then just to end it out this is uh just to go back in time this is me
way back in the day yeah check out the hair rock and roll man hey flocka seagulls
you know why we're here this is this is actually one of the
first telescopes that i had and um it was an eight inch newtonian and uh my my
dad and myself we actually built it we bought the components and put it together and it's uh not what started my journey in
astronomy but it was part of that journey and uh it's uh um i wish i still
had it but i don't anymore i actually don't know what happened to it i was out of the hobby for a little bit before i got back into it so um it's a
lot of the older telescopes and that that i had uh i don't have anymore so that's uh but i just thought i'd show a
couple images anyways for you guys very nice check it out and and sort of uh brag
about that 127 a little bit hopefully i'll have something to brag about next week
so you know yeah i look forward to seeing the results that you get dan yeah it's gonna be pretty cool but um yeah so
so it's been it's been a great night so just uh yeah that's all i got that's great yep and and before you take two
guys go uh daniel i've posted um askforworldweb.com that people can go
and visit sean you teach people um uh how to image process and i do yeah
they can they can they can go to visibledark.ca uh that's my website and uh there's
information there um i've produced two tutorials um for pixensight uh to help
um beginners get uh started in it and i also do one-on-one uh tutoring with uh
individuals as well that you can hire me basically to uh help you
navigate your data and uh learn how to process one-on-one great yeah
what better way to learn it so it's awesome yeah yeah absolutely that's awesome
okay guys thank you so much uh thanks for having me i hope to have you on uh
next week's program uh the theme next year or next not next
year but next week uh will be um
uh uh stellar streams so you know there are streams of of stars that flow through
galaxies and uh but there's other meanings to stellar streams as well so
like we're streaming right now live and we're talking all about the stars
um our next uh speaker is adrian bradley adrian has uh
that's right adrian has been on many global star parties and uh
uh he is always showing us mind-blowing nightscapes and so we're going to turn
it over to you adrian all right so let's start i'm just going to start
right away by sharing my uh screen too i've gathered all the images that i'm
going to use and some of them are probably i'm going to spin it in a way
that makes you make you think that you're still looking at starscapes um
so i'll start with the image that has defined the weather that we've been
seeing lately lots of these clouds now this is back in the winter but
the snow has melted but the stock the clouds haven't really gone away
um as i was looking at um i think bob figate's uh
presentation i noticed the attention to detail that he had and i thought what a great person to
you know listen to the way that he he sets he gets his images he he knows
enough about the equipment he's using that he's able to get the type of images
that he does and it's something that i've strived to do in my own images
um coming from a photographer
um if you are out there and you're interested you're you're more of a
photographer and you're interested in now transitioning to get nightscapes i've
had a few people say i'm interested in doing nightscape photography or landscape astrophotography
whatever it's called they could come from any kind of world
which is the world i've kind of gone back to um the world of bowling where
you're shooting in low light and you're trying to capture motion and
you may not always the motion is a lot faster than when you're tracking
night sky but you're also trying to capture certain moments with a certain camera it might warp
the moments are warped so i would have to seriously process this or i can just try i can take other shots
and now i can get a good shot that's not worked now these are
local guys that are good at bowling but i also had the opportunity
to take some pictures of some professionals um you're looking at some you're looking
at different images and i'm going to somehow tie this tonight photography
what you shoot at you may get something that doesn't look familiar but it's a
part of what you're doing or you may get something that looks familiar
this happens to be a professional bowler here that pulled the same sweeper that i bowled in
this gentleman has had his professional card as well and you can see the similarity
and this gentleman with the two hands is also a professional
and you know you see in some of the photos i showed you see some of the similarity
in the night sky what people will look for is something similar and a lot of the milky way
photography becomes the part of a core why because it's a something similar that makes
sense that um that we look for in photos to say okay i
have a good photo because i got this but there's a lot more to it
you can do birding photos for instance and
scott recognizes this as an osprey carrying dinner
you can you can or you can try to do something a little more dynamic
and catch birds in the act of fighting each other like this
and you try and do something different with your birding so that you're not just catching the
same thing you're catching something unique that um that isn't seen very often such
as a juvenile bald eagle flying upside down yelling at an osprey because the
bald eagle just stole his fish so you come from that world of photography
take it with you into nightscapes here is the cygnus region when you're at
a border one site like okitex which is where i'm going to be going soon why not shoot at the cygnus region
there's cygnus this is with and this is with the stock camera here the telescope's here this is
what okey text looked like facing to the northwest um generally during the time that we go
late september early october it's a beautiful sight i may try and get
a um get a few more images of this when we go down and shoot it with the modified camera
why not try this and see what you get leave the sky glow in
and see what hap see what happens to your overall picture when you're coming from a photography background and you
may not know that this little thing here is actually the north american nebula and the pelican is hard to see when
you're not using um you know when when you're not using h a or an h a modified camera you
can still see some of the uh the ha light that comes through this
with legit with the 30 second exposure you know try shooting at that the winter circle rises try shooting at that and
see what you can get you know the milky way may not be bright but and there may be haze out but that
might grant you stars glowing bigger the larger stars glow
bigger and you may end up with a really nice landscape just overall landscape
photo um in in astronomy the stars can take the
center stage and the landscape is merely framing it and if we go back to
this image that's exactly what i did with the this is
there's a cross of billy joe this is about an eight second photo
i'm going to actually look at that i'm going to go file information eight seconds f14 50 millimeters you can
see m8 and barely the triffid as well m17 m16 the light from the sagittarius
clock the uh star cloud and with eight seconds of exposure because
of the dark sky with a little coma correction i can get rid of this the way that these stars are being
it looks like a big old circle here but um but that's those are the sort of
creativity that you can display rather than just looking for the same
shot of the milky way going across look for different shots that show
different things the beehive is trapped in the zodiacal light here these are the images i've shown on the
show before but it makes it very very interesting
when you zoom in you see different you see all of these stars here to the point where
there's just a lot more there than you expect and this bright thing isn't a star
that's m41 um didn't have quite the uh granularity so you can't quite get all the stars or
any of the larger stars that are here but everything you see here is out there in
the sky and capturing different things and trying to capture different moments
is um is what makes your photography
it isn't so much as standing out as it is taking something different learning from
it seeing something else that's in the night sky and
i'll end on the fact that here you have a nice picture of a sunset and prior in progress
you could rename this as starscape because well the sun is a star so that means
this counts in some ways as a starscape even if it's just a star of one and it's blocked by
some nebulosity this is where you combine your terrestrial photograph with
the uh things or the light that's in the sky and you understand
what it is you're taking a picture of something 93 million miles and i hope i got that
right away providing enough light and warmth and heat and everything else
that it provides and distance the right distance and don't be afraid
to shoot straight at it just don't hold your uncovered censored long remember what
the astronomical lead says do not look at the sun directly without proper equipment there's more you know
there's more to it and uh do be careful when you decide to shoot at the sun
if it's too cloudy to get nightscapes you can make some interesting pictures
using the sun so be creative with that and don't be afraid to change
exposure because you never know what you might get so not only with regular terrestrial
photography you want to be creative with your nightscapes your astrophotography all of those were
single shots those that read skies up magazine will recognize this one
this is a different region of the milky way that doesn't get a lot of um attention because it's the orion region
but landscape astrophotographers are discovering
some of the things that they can do here in the orion region
just because it it's a very active as far as nebula nebulosity goes
it's a very active region and can be quite beautiful if imaged
in a way that shows what's there and in my mind if you can do it without overdoing it you can you get
data that's really there and it can it can still make for a beautiful image so
you don't have to compromise between detail that's there in a beautiful image depending on how
you frame all of your shots and go out there and create
and there are formulas that you use there it's about understanding your equipment
but it's also about seeing the image and saying how can i capture that bring that
back so that i have a copy of that and i can share it and in fact
this image itself one of my favorite places to go that i use as a background
for my computer screen is another example of me just saying i'm
not worried about all of the man-made objects or the even the slant of the wide-angle lens
i just want to capture a moment in time where i was standing there looking at the lighthouse
with the lake in the background and the milky way overhead and i ended up with this photo
i can always go back when this scene repeats itself and see if i can do
something a little bit different to um to mark the passing of time
to you know to in contrast to this photo you know the deep sky astrophotographers
we shoot the orion nebula over and over again but each shot that we take teaches something new about the image we may
pick something up in the orion nebula that we normally don't or we may shoot the orion nebula and say this time i
want the trapezium visible how do i do that you know we just had um
you know we just had a talk on that and um each time even if you're shooting at the
same image be creative and see if there's something different you can do
to show something another aspect of that image that um
that teaches that teaches you something new about it let your photography help you discover
things and not so much you know i want to get a good picture i can't wait to put this on
instagram and i can't wait to see how many likes i get you know you do it for the science and you may be
surprised um how well the image comes out because your focus is on seeing what you can
learn with the equipment that you've got and um and so scott that's it hopefully you
liked some of the bird photos i snuck in there i love it and uh i really enjoyed it
adrian i have a question so any evil will be a stellar sea eagle sorry
say it again i said any eagle can be a stellar sea eagle um just about especially if you shoot at
the eagle nebula if i had a shot i mean the only shot i had at the eagle nebula was this little
pea-sized thing so i couldn't make the you know if i were to go in there and do some
uh deep astro and then put the two side by side pillars of creation and the
eagle flying backwards i think the eagle was just about in the same orientation i
mean that that would be a cool shot i'll have to i'll have to put that as a goal to uh
get a real legal eagle nebula well they're both real that's that's the one thing about this all of this stuff
is real and um it's it's a joy to capture it on a cmos sensor and
present it so so excellent yep yeah you had some great images there
adrian that was fantastic the nightscapes were fantastic and you really actually you know i'm not gonna
look at things the same now that you said about the sun being a starscape that completely changed my perspective
in terms of daytime shots and uh the clouds being nebulosity and so forth that's fantastic perspective yeah really
really like that yeah a lot of our problem when it gets cloudy or some other limitation comes
what do we do we shut off the rig and we go inside and we watch youtube videos on how to better do our astrophotography
but if we look at it and say well what would it look like if i shot it through the clouds that's part of what the
landscape faster photography it's like it or as i call it nightscapes because
sometimes there isn't much in the way of astrophotos but the combination of which it teaches you
something else the starlight coming through it um there's
and if it's okay to if i can find this photo quickly
i like using it because it's an example of well if all else fails just shoot what
you got out there um i went to image and it got cloudy
as i was going and i'll see if i can find it it's the dippers northern hemisphere
um as the clouds were coming in if and i think this is it right here so i'll do a
quick share for you all this is one it's one of the images so i'll go with this so
here you have the winter hexagon region
it's cloudy but you learn that bright stars get bigger you can buy filters to do
this for clear skies or if you shoot when it's cloudy
you get this sort of effect i had one of the images where i did this end up in a
calendar at my job because they thought it was cool this is the um
this is the whole well there's a lot of clouds here so that explore scientific rig that's
shooting at orion right now probably isn't getting a whole lot but
you can still look see fifth and sixth magnitude stars of the little dipper
with this exposure you can still see the stars of the great bear and leo's
getting stretched a little bit over here where the stars are really thick and then there's also light pollution here
from a neighboring town you're not seeing any stars but up here
you're still seeing stars even though even though my tracking didn't go so well but you're you're still seeing the
bright round stars and this is interesting too the um
bright round stars if your tracking is not that good but you've got a bit of a haze going
you still you get you get dashes but you still get round stars in the major
the major stars do be the pointer here and i think this is mirac i know that this is al kade i used to
look for m51 the light from m51 coming off of uh
alcade here you'd barely see it i can't tell you that that's it or not that there's life it would be nice if i
could tell you that there is light from a galaxy 51 billion or 51 million light years away
peering through our clouds that would be awesome to tell you but i can't because i'm not 100 sure that is light but it is
in just about the right spot for where m51 is it's close so
i would have to look at it and make sure that that's exactly what i was looking at but that's that's a part of where you
say you can take any simple image even this and you may discover you captured something you didn't realize you
captured um just like comment hunters look and go what's that you know i
didn't expect it you can do that each time even with a wide field shot you may
capture something that surprises you so it keeps you going
thank you adrian thank you up next is lisa ann fanning
now lisa is new to the global star party she
was recommended to us through professor kareem jaffer which i'm very
glad i always love new faces uh to come on and
to make presentations i i did learn that you uh kind of got your start with the
royal astronomical society of canada correct me if i'm wrong the halifax center and uh that you are a relatively
recent member of the astronomical association of astronomy of
princeton is that correct yep i live in i live down in new jersey yeah though even i'm a rask member
yeah that's awesome so tell us a little bit about yourself uh you're making presentations um
and uh you've caught the attention of uh some uh you know some great people and uh so
we want to know more sure so here's a little bit about me um i've always been a bird appreciator
since i was a child um i grew up in brooklyn and actually uh after today's events my heart is in brooklyn tonight
so um brooklyn strong um i did love watching the gulls at coney island um
eventually i ended up moving to manhattan boston and over to new jersey
so that love of birding followed me all through those states as well um i did become a full-fledged
murderer haha in in 2010 sorry how to do it well lisa i'm glad i shared those
images with you so you were looking at those things to see if i did right i was
i was we're we're going to be in into touch i do volunteer with
working with beach nesting birds here on the jersey shore um and i do perform other birding outreach as well such as
field trips i met my husband robin cape may we were chasing a rare henslow sparrow that that wound up in a field
and he was standing next to me and you know i heard violin music and all that
um i started appreciating the night sky more in 2019 um as as many birders go
through i did come um come up with a bout of lyme disease unfortunately
which sidelined me and uh the medication which is doxycycline makes you very sun
sensitive and this is actually a common um ailment uh with birders
with uh yeah lyme disease unfortunately you know if you're bushwhacking you end up with ticks and here in the
northeast um it's just it's just an awful problem
so um i was kind of bummed out because i i was feeling all these things that i was losing and i couldn't go birding my
husband said hey let's take the spotting scope out um let me show you saturn because he had taken an astronomy class
in in college and wanted to cheer his wife up you know happy wife happy life so he uh
showed put saturn in that spotting scope and my gosh i was hooked from there
um i bought john reed's book and uh because i just wanted to learn more
um and then in the summer of 2020 i was sparked by neowise
and decided i i wanted to take this to the next level so i joined rask halifax
um and did their explore the universe program which i highly recommend for anybody who
um who is looking for a start to learn how to navigate the night sky
um from there i i was asked to become the editor of nova notes which is ras
halifax's newsletter i'm also a member as you mentioned of the amateur astronomy association of princeton
princeton new jersey uh which is about 40 minutes from where i i live i do run my own astronomy facebook page
which came from came directly out of the uh head of the pandemic ironically enough because
people were feeling that same sense of loss that i did when um when i had lyme disease and
couldn't go do the things that i wanted to do um you know we found ourselves in a situation where we were all on
lockdown and couldn't go to the park so i started issuing these challengers these challenges to my birding friends
and said hey go out there and point your spawning scope take your binoculars just point them up at the night sky and
you'll be amazed what you can see from there i started to see that my posts were going global literally um so
i started my own page back in july of last year and that's how and that's how lisa's
look up was more wonderful wonderful so
quite an interesting journey for two years absolutely
so i did want to focus tonight on migration and the moon and um
it's not just for the birds even though that's what i'll be focusing on tonight but i did want to talk a little bit about insects and um some of the studies
that uh some of the studies there that that have taken place um around
uh periodosity um study for insects that started in 1927
so this goes back a ways um and of course i think many people know that bat
behavior is affected by the moon but also remember that they're dependent on insect activity so um that is definitely
um influenced by the moon but what i love um songbird migration in
the moon phases so this quote i love this quote because uh it was once thought that birds migrated to and from
the moon that was a quote by charles morton who was a 17th century english
minister and scientist this was taken in 2020 this was fall
migration and i was standing outside and working on my explore the moon
certificate for rask and i realized that i could see the
birds migrating in front of the moon which is such a neat thing because here
are my two passions and uh so i was these are captures just with an iphone
and a single shot um the one on the right i was playing with starry sky stacker and was able to stack images of
two birds going over the moon in their and their transition so this is a fun little challenge um that i'm i'm gonna
issue two um to the audience here today
beautiful i thought i invented something new i was ready to cash in on my millions but nope
uh so this this idea of moonwatching for migration was first described by george lowery and
robert newman in the 1940s through the 1960s and they figured that if you point a telescope at the illuminated disk of
the moon you can facilitate the ability to see birds migrating at night so i had to you know
unfortunately break that deal with the house that i was going to buy on the beach so
um so this definitely piqued my interest and i started digging deeper and found
that there was a great study done out of london university in sweden that was published in 2019
and they looked at european night jar migration in the moon so they charted the activity of 39
european night jars so this is the cousin to to our whip or will or the
poor will family here in north america and of course you know they discovered
nocturnal hunting activity for flying insects doubled on moonlit nights because that's when the bird that's when
the bugs are out flying around but even more interesting they found that the birds would all
depart for autumn or southbound migration consistently 10 to 11 days after the
full moon and they found that this species was synchronizing their migration and flew off at the same time
so that was uh that definitely got me going and started crunching some numbers
on my own uh this is nexrad so for anybody who's not familiar with nexrad
um here in north america we uh have access to the next generation radar or
nexrad for short and they're real-time maps that show concentrations of migrating birds bats and insects
and uh cornell lab of ornithology actually produces these maps but it's a
whole consortium of organizations that have uh have helped to underwrite this this effort
and what i did here was i mapped out the bird migration this was southbound
migration in 2021 of the full moon on the left versus the new moon and you can see consistently
that um the migration traffic rate is much higher on the full moon
so this is just one demonstration looking at those two days i took those numbers even further and i
decided to crunch them and and chart them and you can see the dips around the new moon
sure enough uh if you look at that full moon of september 20th you see a peak now i'm going to point out um something
that's that's a little skewed here but right before the new moon in october
you see a little bit of a peak and then the dip at the new moon so here on the east coast we had some an
awful run of weather and those birds were backed up for migration so that um
that anomaly can definitely be explained away it's the songbird migration and moon
phases this is where i'm gonna this is where i'm gonna issue the challenge uh that's video i took recently last month
um of a bird flying over over copernicus crater and the conditions were right
that night for northbound migration so this was march 16th um this was at 10 o'clock eastern i was
just out with pointing my scope at the moon and we had uh winds from the southwest
which are ideal for for bird migration um and the moon was 97
full so for i would say for the hour that i was out there i encountered
maybe a dozen or so of these birds without keeping an official count so april is is sort of the beginning of
migration here in new jersey um and so i'm going to be out there with my
telescope next next full moon for sure tracking this
so i said i was going to issue a challenge right how can you try this at home it's really basic equipment if you
have a spotting scope of telling a telescope which i think many of us in this audience do um you can even watch
it with binoculars um a cell phone if you wanted to take video or or or
you know a snapshot and a smartphone adapter for recording video if you want um i do tend to freehand but smartphone
adapters a lot cleaner and a lot better experience you want to consider your timing so peak
northbound migration begins in march or april that's starting in point south so along
the gulf coast that's that's when it starts when you move up the coast for example in the atlantic flyway um you
know we're looking at peak migration we're getting there now in april but may
is the hot month so consider where you are in this map and then peak southbound migration
begins in july and august from canada it it also does depend on species so we have um shorebirds departing here in new
jersey uh around july or august but when you're talking about songbirds for new jersey uh october is the hot month
so choose a night around the full moon i usually recommend plus or minus three or four days for best results you want to
check the winds as i mentioned north brown northbound where spring migration you want that that southerly component
because it pushes the birds you know birds are are very energy efficient so they're going
to go when the winds are in their favor same for southbound but you want that northerly component
you want to set up your optics as you would for any moon observing session i always recommend taking video because
you can always extract it also try slow motion video and then once you have your images you
can even extract them and stack them like that second photo that i that i showed originally uh where you see the
two birds crossing the moon and you see their path so i just wanted to say thank you and um
thanks so much for this opportunity and if you have any questions you can contact me through lisa's look up on
facebook um if you have if you want more information or just just message me i love to talk to fellow bird and
astronauts so thank you lisa i just joined your uh followed your
page so you've got one at least one new subscription already
awesome i want to say i want to see some pictures that's what i want to say yeah
i should i guess i should send a friend request um yeah if that'll
right on yeah if that'll work yeah i'll send a friend request lisa can i just ask a quick question um it's
sean um i was just wondering if you could demonstrate on nexrad um how you got the
bird migration map and stuff uh demonstrate it live sure yeah
is that possible yeah let us show you just so people can see where to go and how to do it how to
access that information
so bird cast is um the real time bird migration maps let me
change my uh my sharing here
okay can you see that yep i can see it great uh yeah so that's birdcast.info
and uh you know here's here is the team that puts this together
so um i mentioned there are a lot of people nasa i think also is one of the one of
the underwriters so here is here are the migration tools and they do it around the peak season so here there's a note
um saying that the forecasting will end around june 1st so they'll shut that down when there isn't migration going on so this is
specific to the bird migration forecast yours tonight
okay so they're predicting 104 million birds will pass through uh the us tonight
wow that's incredible and then if you look over on the right of the bird cast you could see the
migration intensity you can see you can see you can see where it is it's it's low in the west right now but um
you know medium-ish if you will on the central and uh eastern flyways
up up to about new york state do you know of uh any maps
such as this that um display the migration paths within canada since
that's where i am is there anything that you're aware of i i am not aware of hand but i can
certainly pass that information well i'll look into that it's a good question it would just be interesting to see the
uh the canadian component of the migration paths as well yeah
because that's definitely going to start to heat up as well in the next few months yeah for sure
yeah i don't know if anyone else has anything else to say but uh i guess we can pass it back to scott
it's scott on mute yeah i just sent the friend right unmuted that's right yeah yeah you were me
something called the canadian migration monitoring network oh okay all right great i'll look that
up canadian migration monitoring network canadian migration monitoring network
the cmmn it's on birdscanada.org
oh okay it would be interesting to put those two these two maps side by side i think on a
heavy migration tonight and see you know sort of where where it stops because when birds hit weather they'll get
grounded or um so it'll be interesting to see if they continue on to canada on one particular night or if they're grounded
you know they hit weather up in new york state or vermont that'd be interesting
so it's not a heat map like this is i mean this interactive heat map is really cool you know so but um but there are
resources out there for sure yeah look into that
thanks sean that's great thanks lisa thank you great yeah it's also uh lisa one of the
other things to point out is the importance of dark skies to birds you know absolutely uh since the majority of
of the migrations happen at night you know there are unfortunately they get uh turned around
because of bright lights from cities um and uh and from tall buildings there's
millions and millions of birds that die from bird strikes on buildings so you know
i'm not sure what the fix is for that but certainly um
you know maybe smart lighting practices where lights are turned off
and they don't need to be used um you know there are so many you can drive through a lot of cities and you see like
all the lights on in an office building and no one's working you know so
they say that even 20 minutes makes a difference i i um before the pandemic was working in
jersey city and on following heavy migration nights would find lots of dead especially white throated sparrows
certain species in particular yeah woodcocks to hit buildings in big cities
yeah so yep yep and uh you know so save some money turn off the lights save a bird
right absolutely saving a million birds
lisa thank you so much for uh for coming on and um i think it's about
time that we took a um we took a ten minute break and um
uh there's a a little feature in there as well and uh
i also like to do some shout outs for um the people who write books um
uh in our program uh that appear on our programs of course uh david levy's uh
autobiography is there and iker david eiker has mentioned a children's book a
couple of times so i did a little uh video uh a plug for that as well so you'll see
that but uh that's by mike bakitch and david eicher they collaborated on that
children's book about space exploration so uh you're welcome back anytime lisa ann
and uh uh we also being that you're so much into birding we'd like to have you as a featured
guest on uh our on the wing program which is all about birds so i would love that thank you we'll hit
you up pleasure okay thank you very much all right so it's time to go grab that
sandwich and uh stretch your legs and take a little break and then we're gonna come back with um jason gonzale the vast
reaches we have marcelo souza from brazil uh cesar barello joins us once again
from argentina and um uh and then we end with maxi fellaris
also from argentina with astrophotography to the max so
we'll see you in a few minutes
so lisa um after you mentioned the uh limes lyme disease that afflicts a lot of birders i
decided i must be a uh a fair weather birder or a concrete uh
street birder if uh we do have a metro park here kensington metro park
uh it's quite a nature preserve and a lot of uh a lot of people shoot
um at this park oscar there's nests built osprey obtain it there's eagle bald eagles
there great blue herons you saw some of those in the pictures and um so a lot of us are spoiled we
just show up with a camera sit on a park bench take aim and nature just waited
not having to walk through any of the brush to get to the action having to sit still don't even need
camouflage on your big lens you just show that's crazy you know we got to get that one extra
species so we have to bushwhack yeah i i have a friend who does that and
um he's uh you know he he's very good at getting the species
you know that that sharp beautiful photo isn't his thing his thing is uh he's like a hundred or so
species under his belt i think or he's trying to catch somebody who has even more than that
so right that's that's a serious birder so i was younger and crazier
i salute all of you who know a lot of species i i generally know
the like the common seven or eight that we see at some of our metro parks and hang
around me and my husband we'll teach you everything you need to know all right when it's cloudy outside
that's uh that's the other thing that gives me peace um oh yeah oh yeah
and we're waiting on the hummingbirds back i can't wait it's any any day now
yeah i got one good hummingbird photo submitted it to one of the nature
facebook pages and it ended up being the cover page for about a week
capturing the uh hummingbird is it's just cool to watch it go and it reminded me of
shooting at the butterflies it was almost the same type of thing it's like yeah just
you know shoot fast shoot quick because uh those things those wing fly actually
froze the wings on a hummingbird oh sweet yeah i had to i had to do some
editing so so sean the editing that you learned from uh editing nightscape photos some
of that goes into the birding editing too topaz denoise which is one of the tools a lot of a lot
of people are using because it's it's gotten really good at separating signal from noise really well
well it does the same thing for birding photos too it'll it'll separate the now i almost
think it was originally for birding shots and then it just it's like they've tweaked
it every month or every few months to get better and better at different kinds
of uh images and it really does the birding images it does really well
i've had i've had images like the the low lighting images that i took you
know i i threw those through um topaz denoise and
you know it it gave me the type of image i i was looking for and um
i i've been happy with it it's yeah i haven't i i actually haven't
tried to opacity noise at all um i do i i don't do any birding uh shots and
stuff like that but um that i would need to use something like that uh but i've heard good things about
it so do you do adrian do you do most of your processing in photoshop or lightroom
i do most of it in lightroom for tweaking colors and things like the
image behind me but i'll take it to photoshop and run the astro tools
they've got the enhanced dso objects that tends to work well with milky way
shots it tends to make it brightens the milky way region without screwing up the
uh land if you have some sort of landscape yeah you got a mountain or
or you just have a mesa because that's all you can afford right now um but the me yeah it doesn't ruin the mesa
so much as uh really it still makes the milky way stand out a little more
no matter what part of the milky way you shoot so um so i use photoshop for that i use topaz
denoise um somewhere in the process to if if the shot yielded a little bit of a
noisier if there's a little more signal to noise i will send it through topaz
denoise and um let it clean some of that up send it to
photoshop to brighten up whatever part of the sky and then use lightroom cc to just do the
final edits where i'm doing things like um their dehaze slider
that you know darkens the sky a bit gets me more of the kind basically getting more
of the contrast that i want out of the full image you know whatever however that looks without trying to overdo it
i haven't gotten into using pixen sight and it looks tempting for all of the the
way that it can be set up i just have to sit down with you or anyone else and just say all right let's go through you know
let's go through step by step here's a here's a image you know the pink image
from the aha camera of milky way over a lake because it's my
favorite thing to shoot and now it's time to turn this into something
um usable and okay yeah what do we do so
i would be yeah i'm getting to the point where it may be worth it to
set up pics in sight because it looks like you can just run through a few scripts
and your processing is basically hit a button and have it go through the routines that you want it to do to your
image and if you like the result export to some degree yeah to some degree it's not it's it's a
little more involved than that of course but um there's uh there's a lot that goes into setting up
the processes uh the parameters and so forth and getting the the right tweaks done to them uh to apply it to the image
um before you apply it to the image but uh i've actually never done uh in pixel
sight a milky way shot um all of the all of the work that i do in pixensight is
deep sky objects right yeah so i'm not sure how it would lend itself to something like a milky way shot but it
would be interesting to try that's for sure yeah i have astro flat which is nice
when i when i do actually try a deep space shot and that looks like it works really well
i tried it on a full picture and it broke the uh landscape i think there were gaping
holes in the landscape and you know then other things went wrong so i said that's it's a little too much it
makes the sky the you know it it takes care of all the gradients in the sky but it
it takes the ground right out from under you too and then you're you've got it you've got a weird-looking kind of image you lose your light tower
did you want it to be a part of it though
i can see the pink reflecting from me from scott's uh screen
[Music] [Applause] [Music]
i was going to say to uh for you lisa i'm not sure if you're familiar with
flap canada no okay it's
hard to talk over the music but um flap canada is at flap.org
and they have a lot of good information on there they're very active in
outreach educating people about birds and the
the challenges that birds are experiencing right now with regards to
urban design but also light pollution and so forth so it's a really great resource it's got a
lot of good information on there it might be something useful to you and um
yeah flap.org yeah check that out for sure thank you check it out just something i thought
you might uh be interested in i also follow um there's a
a website called journey north and they track the uh hummingbird migration
yeah and they have they actually have a map that uh is a user interactive map where you can take photos of the
hummingbirds that you see in your backyard and you can post it on the map and you can actually get a visualization
of where the hummingbirds are how they're moving along as they do the migration north and south
you know and that's a great website and people get excited about that yeah about
creating hummingbird gardens at our local garden center with my husband and uh
[Music]
[Music] it's too bad we couldn't mute the music
i could hardly hear i was trying to talk [Laughter]
well you're muted scott all right well i'll hear you guys
there you go that's for sure so uh we're back uh hopefully uh you enjoyed that little break and um
uh sean was uh talking about a website called flap is that right yeah
flap flap canada so it's flap.org and they have a really good website very
resourceful website on birds the challenges that birds are
experiencing in our environment in our urban design that we you know
buildings that we build and also light pollution and they also have strategies for how you can help the birds um things
like bird safe windows and and uh solutions for commercial and institutional buildings oh wow as well
as residential and that so it's really good and the other website the other website i mentioned
they're talking about yeah and it's like the numbers as i'm watching is racing up like crazy yeah
yeah it's in it's incredible the the number of birds that get killed due to impacts with uh
buildings and whatnot so and it happens during the day and it happens during the night so
um the other one that i'd mentioned to lisa was journey north where it's a
an interesting website for the the map that shows the migration of the hummingbirds and it's user interactive
so people anybody with a camera uh can take a photo of the hummingbird in their
backyard and post it to the website and you can actually get a a a visual
where the hummingbirds are what type of hummingbirds are are where along the migration road as they progress through
it it's really interesting next one i'm posting these in the
live chat so yeah for those of you that are interested in um protecting birds and uh
and and you should be uh because uh protecting uh you know nature and birds
amongst all the other things in nature directly linked back to us we're not somehow disconnected from all this stuff
so right that's right yeah if you're interested in just protecting your what yourself
and your family new jersey audubon has a lot of great resources lights out baltimore does a
fabulous job at um talking about mitigating those risks and and some of the studies about turning lights out for
20 minutes and chicago audubon also has great resources great all right
so now you all see that uh the global star party slash on the wing
tonight we uh we we love both birding and the night sky the two are related and lisa just
showed you how connected yeah and uh yeah there is the kind of lesson of of uh
you know the global star party is that we're everything's all interconnected all interdependent you know and absolutely
so that's right it's all part of the universe well next up is jason ginzel uh
jason is a an amazing astrophotographer he has been on global star party uh several times he
has um very popular social media um uh you know outlets and uh where he
posts his images um but um i always love to hear about jason's uh journey in
astrophotography um because he's he's not too proud to show uh his very early attempts uh
uh you know in contrast with where his journey has taken him and
those images are nothing short of breathtaking so jason uh you've got the stage here
thanks for coming on yeah thanks for having me again scott um i don't have anything old to show you
and i don't have anything bird related so i'm sorry about that ahead of time
um but you know i can i i live near adrian
and i can feel the pain with the clouds and not getting a lot of astrophotography done so you know i've gone back and re reworked some older
images and worked on some that i uh shot earlier in the season and never got to so
that's what i plan to show everyone so let me share a screen here i'm sharing a different screen that i'm
uh working on but that i'm that i have them that i have the meeting on
hopefully this comes through let me know if you can see it yep it's coming all right so
we'll start off with a topic that the the subject that needs no introduction right i think most of the
people on this meeting and watching out there know
a little bit about this target uh may have not seen it um in this type of exposure before so i'm
going to kind of blow this out jason
i have seen an image like this before but it was a combination of all different kinds of
telescopes that made the images is that similar to what we're seeing here yeah so i'll explain a little bit about
what you're seeing so this this image was shot entirely through
a 40 millimeter aperture telescope the tpo ultra wide so it's a 40 millimeter
aperture 180 millimeter focal length tiny little telescope the telescope's about the size of a can
of red bull and then i've got an asi 2600 mm camera on the back with a big filter
wheel with two inch filters so the camera and filter wheel assembly is this massive
hunk of optical machinery on the back of this tiny little telescope but the advantage
to that tiny little telescope is it shoots a very wide field image and a fairly well corrected one too out to the
corners you know we're getting sharp stars and and so it's been a lot of fun shooting with that telescope and this is um one
of my early images with that scope this is the belt of orion or the sword
of orion region um with the well-known horse head and flame nebula there in the in the left
and then the orion nebula off to the right um it's it's cool to see it like this
because it's um unless you see people present images with a
telescope or sorry a camera lens or a mosaic like you said scott multiple different
shots it's hard to get this field of view but uh it's possible with this system
and it was shot in with the luminance as narrowband light so i've got a radian
triad ultra which is a multi-narrow band filter and i use that in front of a narrow uh
in front of a monochrome camera to shoot a narrow band image basically collecting hydrogen
sulfur and oxygen light all for the luminance information
and then i went back and shot through red green and blue blue filters to present the color image
in natural color although the natural color is overlaid on top of a narrow band image so it's a it's a little bit
of a unique way to look at it um a little bit different than a lot of them you see out there so you know i was
really happy with how it came out in the depth of exposure in the in the dim areas
and also you know some of the details in these areas that are
you know not only these bright uh commonly seen areas but some of these dimmer
zones where you know you just don't normally see those presented in an image so it's
a lot of cool undulating waves of hydrogen gases out there it's beautiful
and then um yeah over here it's uh what is this and you see uh
it's a 1999 you know it's a little h2 region and then inside there it's got the tiny
little keyhole nebula i don't know if you've if anybody's familiar with the holo image of that but it's a little
tiny window into the background space here right right within all this nebulosity
and the running man nebula orion nebula and it was shot with a
hdr process to preserve the details down into the core of the orion nebula
jason what's the uh integration time on that uh [Music]
total is 13.3 hours so i shot okay but i don't have a break up here but i shot
the majority of that probably eight to nine hours was with the radiant triad ultra and then i shot a
little bit of luminance to bring in some of the the uh dusty nebulosity that's not
captured in narrowband and so that's blended in there and then rgb for the balance so the total is 13.3
hours nice it's a fabulous image really fantastic yeah it's something i've been
doing i appreciate that something i've been doing with a lot of these recent images is the
now that we're in this arms race with um star removal software where um we've got
star exterminator and starnet both releasing better and better versions it's a lot easier to
remove stars from images and process the star layer and the
in the nebulosity separate so yeah absolutely a purely star layer and a purely
starless image where i can just click on and off the stars because if this will refresh
i am stacking something in the background and oh there you go
you see that right yeah start with image i mean um
love it or hate it it really allows the eye to concentrate on the details of the nebulosity behind even
with the you know the star field i had on there was minimal uh it does really help to
pull the stars out and you can just see all the all the details yeah i think that's there is some use
especially when what you have is accurate yeah you can focus on that
the stars i think just give it sort of the if i were floating around in space
that's what i would actually see is a ton of stars and um i'm actually thinking you'd see way more
than that yeah than when you when you add the stars back in but if you were floating
around and had on your you know your filter visions where you
could see things like this right you'd see i think you'd still see
tons and tons of stars you know as a and it would just be a part of what you're looking at so
i think there's there's value in all of it yeah so another i shot another image here with the same
process so this is the flaming star um tadpole nebula
region um what is this m38 i believe this open
star cluster down here so again it's a expansive view i think it's
five degrees by seven and a half degrees uh field of view just a massive field of view
um and this is in in auriga constellation you know it's
not it's a popular target but it doesn't get as much attention as the orion and
riot region which is right south of it but again we can do the same sort of thing where we click on and off the star
layer
man my computer is bogged down i apologize for this
maybe it'll refresh a big image right yeah i've got a lot of i should probably
start closing these yeah each one of these images then because i i drizzle this data so
each one of these is about a 85 megapixel image so yeah i've got a lot of open here
um [Music] but you know these these areas look cool
and you know a surprising amount of detail coming out of a really tiny telescope it's like two eyes and a beak
like maybe some sort of uh raptor bird maybe like an owl or something
yeah we just we just tied your image to uh
we made it happen you couldn't do that jason but here you are oh you know what i'll let me do this here
um yeah i think if you turn this
let's see counterclockwise yeah then it really starts to look like a
bird you can see these two eyes in the in the beak oh man see look what i'm doing to myself
the detail is just phenomenal it is incredible you ever seen it take this long to
rotate an image yeah when i only had four uh mag of memory you know four gig of
memory in my computer everything's not that long pull this closure in the background here i have my
telescope outside and it's looking at the moon so i've got a live view of the moon i also took
images of the moon and i've got it stacking in the background so that's why this is
barfing at me but so the scope that you use there is that
similar to the ascar fm a180 is the same telescope different color
just a different color okay all right yeah i mean it's it's the same telescope it's just it's branded and sold as a tpo
which is opt's house brand okay all right that makes sense then yeah i actually have one of the fma 180s and
now now you've got me interested in using it yeah i mean the the field of view is just awesome um
unfortunately like now with it being you know galaxy season like in the middle of the night there's nothing to shoot
because i yeah no galaxy looks good this wide um yeah unless you're looking at andromeda
well if you're going to you go at virgo you can you can make yourself a deep
field we're gonna we're gonna skip off that it's taking too long to rotate that one
all right um so this is the uh siamese twin galaxies these are uh
interacting pair of galaxies uh shot this one last year um finally got around to
editing it this was shot on the 8-inch edge hd telescope
and i've got 19.75 hours in here
l rgb natural color
beautiful beautiful i don't i don't have the distance to these right
now but um which objects are these again but they're they're called the siamese twin
galaxies well they were and then nasa realizes there's a little bit of insensitivity in
that name so they changed it to the butterfly galaxies but i have the numbers here it's ngc
4567 and 68. 4567 virgo cluster galaxies is that what
they are i believe they're in virgo somewhere yeah yeah virgo cluster
uh these guys are about 60 million light years away yeah what's their new colloquial name now
well the butterfly galaxies okay yeah
so yeah they're listed both you know butterfly and siamese twins
okay so they yeah for for reference yeah
august 5th 2020 nasa announced they would not use the nickname
siamese twins you know so the other cool thing like i was talking about
star removal software that software has gotten smart enough to now you if you feed it a galaxy image
it will remove the milky way stars but it leaves all the background galaxies so that's actually what you see in this
that's pretty cool no stars just all background games those are all galaxies yep i was wondering that when i saw the
image it i knew you had a lot of other galaxies in there but now you've just shown me which ones
really are the galaxies yes if you look at you know the reason the
star software doesn't take these away is because they're not circular objects so they're extended
galactic objects and you can go in and verify that these are all
whether you're really stellar objects but yeah there's incredible yeah i thought i thought starnette or
pixensight worked with um you know where it would actually plate
solve so every little dot on there it would decide if it's a star or a
galaxy and it would not use that i don't think it's that
um involved yet i see that technology could come along at some point but i mean right now it just looks to see if
it's a round object and if it is it takes it out okay so in this image is
there this um uh is there any kind of uh of this
integrated flex nebula between the the two closer components it looks like there's
like this sort of ring or yeah
i don't know if you would call it integrated flux nebula um i mean
but it is you know they're interacting and there is like a stellar stream or uh yeah you know around that the outer lobe
of this this lower galaxy
so along these lines i also have a second galaxy image to share this is
not that one this is uh m100 mm-hmm
which is a fairly well-known messier object
and this one was shot with an h-a-l-r-g-b and this totaled 28 hours of
exposure and you can do the similar sources do
you do all your processing in photoshop then i do uh no i do all my
all my stacking and um initial work in pixel site and i
moved to i usually move to photoshop after i stretch it
and i say i do the rest in photoshop i'll use some tools occasionally um
you know go back to vic's insight for it but mostly i stay in photoshop i just
get a little bit more free it's a great image really fabulous
details in there again yeah it was like i like this core because it it looks like a blown out blob um at
this scale but if you zoom in on it come on computer
look at that there's quite a bit of detail down in there that is amazing if
you ever get a chance to look at the hubble version of the core of this galaxy it's amazing
but it's a classic grain design spiral
and again you know with the stars turned off everything you see here are background galaxies and smudges
uh so a couple weeks ago i was having after a night of uh deep sky imaging i had the telescope out
and the sun was up just above the horizon and i saw venus shining there so i
uh pointed over there and i took a shot in uh near infrared and rgb
and that's uh i love doing these crescent shots of venus with them tilted up on their side
like that but it reminds me of something out of 2001 of space odyssey i mean it's just yeah it looks like a it looks like
an album cover from the 80s or something absolutely i mean i had some fun with the colors obviously but um you know the
the planet venus was this is shot in our jeep with rgb filters so so you've got some sort of shine there
because you've actually got the whole disc so what what's throwing
you can capture the dark side of venus i there's no doubt to help this one
along a little bit but i've captured in the past the
dark side of venus and near infrared so it does glow um because of its heat signature okay
around around a thousand nanometers if you can get a filter that light isolates that you can't capture the dark side of venus
and i've got you know many images where i've i've captured it and i've tried to extract
detail because you actually can see surface or sub-cloud features
uh with a near-infrared feature but i've never actually got in detail the problem you have with the with capturing the
dark side of venus is that the light side is so bright that it
washes over the image so you you've really got to take care with gradient removal and all
kinds of tricks to to get the dark side right yeah i was like well that's not earth
shine so thanks for the explanation because that i think that's the first time i i've
seen your image like that before but it's the first time i'm looking at it and realizing wait that's a full disc
you know so so yeah that's you know when we look at it through the telescope we never see the full disc we
see some form of the crescent this is also a really good composite right here yeah
so this past week we're coming up on two years until the next
[Music] total solar eclipse that's coming across the us
it's actually going to be april 8th of 2024
so in honor of that getting ready for that i kind of went and retouched the
totality image i shot in 2017 and with five more years processing
experience under my belt i was able i've always wanted to dig down and get these coronal loops that are in close to the
sun and that's kind of what i focused on for this image
now did you pull up the shadows enough to get the actual mario on the moon
as it appeared yeah literally that's from the longest exposure shot i
think i shot a range of exposures from like 4 000 of a second all the way up to i
think it went up to like eight seconds which was pretty full out but um that movement yeah that's that's from
the exposures this is all yeah so that's that's what that's where the moon
yeah where the mari were if you know a superhuman vision if you looked and saw it i always wondered if you could
capture that and uh that gives me ideas for this solar eclipse
that's i mean i didn't superimpose that moon that's that's the image that's it that that is the moon yeah that that is
always cool to see because you're looking at uh it's like looking at the moon the way we see it
at night even though it's you know it's darker but those features are still
there yeah and i you know i do a lot of solar imaging and and
you know capturing prominences and stuff it's just it's amazing
that i was able to dig out you know all these loops out of that data yeah and stuff that i just kind of
blurred over you know my first time through so i really had a lot of fun uh revisiting this one
really uh really proud of the result finally i was able to get out of it five years later
yeah i think i saw the uh the rays that you've got down there part of the corona i remember
seeing something like that through the telescope and visually um
i mean you can see the corona visually it's just yeah like the camera yeah it didn't have nearly the amount of detail
when i look when i remember seeing it first time seeing it it just kind of looked like
it almost had the look of a fried egg the way the corona the light of the corona just sort of spread out
and you had the moon in the center um all of that detail was there but
i don't know that i looked at it enough to start to pick some of that detail out with my eyes
and then i put it under a telescope and i started to see more detail like the rays coming out and saw some of
the prominences there as well um didn't look at it long enough because it
took me too long to take the look through the telescope the diamond phase was getting ready to start
so we you know we we pulled all our eyes away and said you know cover your eyes
put your glasses on yeah we we were trying not to get blinded when that
when it uh moved beyond yeah so i mean i
i was in a rush this whole day because trying to get down there and all the traffic and everything i finally got set
up just like a half hour before the before totally and i was taking exposures making sure everything was
working all right totality hit and i like i just i was like oh wow look at that you know and
i was trying to take pictures and i'm like i don't see anything on the camera but i want to look at i realized i forgot to take the solar
filter off the camera for totality so i was like trying to take exposure nothing was showing up you are not the first
person to do that so yeah so halfway through i finally fixed that problem and i was able to get one
full set of exposures and um you know
exposures and the filter and i didn't end up getting that so i definitely think next time
i want to try to fully automate a camera they have software that'll
yeah for one of my cameras eos backyard i have an intervalometer
that um you can set up you can put on the hot shoe and it'll do you can set up the
exposures and groups and all that i'll have to play around with that because i think there's
software called the eclipse orchestrator oh cool it's it's keyed into the time code and
it will actually adjust your camera exposures to capture first contact you know bailey's beads
the diamond ring it'll um full hdr totality it'll do it all
that's that takes all the guesswork out of it set it up on the tripod make sure it's tracking
and hook it to the computer and let it go i might have to check it out eclipse orchestrator
yeah i've never tried it um i thought about it for this 2017 eclipse and i
yeah never never got around to it but i think you did fine with what you did
it wouldn't be a star party unless we looked at something in space right true
this is a live view oh look at the clouds just in time um this is a live view of the of the
moon through my telescope i got it set up outside it's hoping to do a little bit of imaging tonight but looks like i won't
be able to but yeah we can look at a close-up
waxing gibbous yesterday copernicus i think made its
first appearance and now um now it's growing larger
there you go there's copernicus i gotta learn a lot we've got rick hill
teaches a lot in his uh articles is uh you know exploration of the moon
and so many craters that you can get the names for and some
of the and some of the information about uh just copernicus tycho
the really bright one whose name escapes me um a fairly recent one to the left
that's not quite in view yet yeah starkist or yeah air starts
no i think that's well that's the way i'd know to pronounce it here stark because that was right this one this this is
shiller crater yeah potato look at the wind
so i was able to uh like i said earlier i got i had this stacking in the background
because i was able to take a set of exposures earlier when the
we lost your audio a bit but you've got something that looks an awful lot like google moon
now this is the moon from tonight so before the can you hear me yeah we hear
you good now so before the uh i was not facing the microphone sorry
so before the clouds came before i started talking today tonight i took a set of exposures
so this is a video through the red filter of the moon tonight
and then this is sharpened and presented for your enjoyment but the the
seeing was really good earlier so i was able to get some pretty good details here yeah you've got the splash middle region
of copernicus yeah i always look for the uh if you can see these four crater lids
and plato you know you doing all right yeah one two three four
knowing that if we were standing there that one crater lit would be big enough to swallow us
right i think those are uh i would i would be lying if i said a
number right now but i think they're less than 10 kilometers across these crater lids i think they're just a
handful of kilometers across yeah that's still
still bigger than us i think you can see our starkists here
maybe barely i think it's just coming in there isn't it is that it that looks like it
i know it's it's deep and it's it's like a very striking
deep and it's a fair i guess it's fairly new compared with all the others that maybe yeah that may be it
i mean look that all right well outside of that i don't
know how much time i've taken up scott but i got some videos i can show
some solar but i can easily let it go if i've hit my time i feel like i've been talking for a while
well let's look at the schedule here we are we're running uh yeah quite a bit behind
right now so i know there's always more from the vast reaches so um
so i appreciate it i appreciate you having me on again scott you know if anybody wants to see my stuff yeah you
can find me yeah i posted i posted a link to your
website so that's awesome and the beautiful uh eclipse shot um
you might have mentioned which telescope you did that with what could you that was with the camera lens that was with
the sig sigma 150 to 600 legs
and a canon 60 60. just yeah so i happen to have the same equipment
the shots i took is with that same type of lens except i don't know jason if you've got the sport
or the contemporary it's the contemporary yeah i have the same lens that's the one that i do most of my
wildlife photography with and um i'm finding it's not bad as a uh
a lens for some um shooting at the sun or shooting at the moon so
yeah i mean i've been pretty happy with it i've shot uh things like uh iss
transits with it and it's done cool it's done an impressive job seeing if i could pull one up real
quick
yeah here's an example of the iss transit with that lens there you go
not bad for um yeah yeah not super expensive but it
yeah if it compared with the right little fit the right camera
it zips into focus pretty quickly and it's it's pretty sturdy
yeah so this was just with a white light filter in front of the camera and ripped off a couple exposures as quick
as my camera would but it only caught three frames i mean that the 6d is not a fast camera so yeah
it only caught it three frames on the on the surface
okay all right well thank you very much thank you very much um
up next is um marcelo souza uh martial marcelo has uh
been on global star party now many times and he is the
editor uh senior editor of sky's up magazine but uh he's preparing for an
international aeronautics and astronautics
event and he'll tell you more about it marcel you want to come on to the program
hi here we go thank you very much thank you for the invitation thank you very much
to be here uh today i was talking with my students
about something that i'm before the pandemic i
did a lot of presentations about the stem that is we are talking about elementary
particles and they also do fundamental particles and
i will shall hear uh try to make a free talk
about this stem because i think that
something that many people have done
and the something that is important when you talk about the elementary particles these diseases on
cartoon that i think that is fantastic about that they are a physicist is really very particular
that he said that quack is nutrients museums all those done particles you can't see
that's what drove me to doing but now i can see them
you have so many particles today then who works with this i i work with
cosmology and i have to study uh
and something that's fantastic is uh here in brazil i don't know any other countries
and when i talk with students from high school and they are
also the students that is is studying physics is in the
engineering at the university in the first years about the structure of the
atom and they imagine they have
the atom the atomic nucleus composed by protons and neutrons
and the first question i don't know why they didn't ask before is if
the electronic electromagnetic force between protons is repulsive
how the protons are inside the atomic nucleus
something that in 19 30 they begin to
try to find a way to explain this then
when they try to explain these now they found two different kinds of force
that now is based on free difficulties
and who predicted first the existence of the defiance
that are responsible for this was your coward in 19th at
five and the pyramids right score very in 1947
with a participation of the the most famous brazilian physicist
that he says a lot he's so famous here in brazil that the
platform that you use to insert our
kuhiko in brazil has the name of the scientist that is
caesar in english i think that this is a lot not to say but since portuguese is
his name he works in bolivia
and they are also a when we go to these small words well we have something very
strange that today everybody talk about this that the audience particles
that he was proposed or by dirk
that appear as a solution of his equations and the deposit that is the
anti-electron were discovered in 1932 by anderson and here you can see
a photo that's the case in bilateral in the position that is
uh anti-electron but you can imagine like this and you see that in the same magnetic field
they go in different direction they have a different choice
from the election he has a positive choice
now everybody talks about such particles even in movies and the many place
and also another strange part was a new dream
that was proposed by paul
to explain what's happened in the balance shelf for energy in stars
and the fam quality neutrino that gave the andrew has found the first time in
1956. let me see how many gold inside
this small world many things are different than we imagined
and something that is fantastic here you what happens when applause during the
latin they meet they
disappear and have own energy here and he is deposit
and here now is the structure of the matter as we know we have two kinds of
the family of particles that are the leptons and the hardness
leptons are the particles that don't have nothing
like electron that is a fundamental particle the neutrino the moon
then these are this you have six kinds of laplace
and we have the harders that are particles that you have with
internal structure they are composed by quarks then for us now the proton and the
newton
is composed by three kinds of quarks and the neutron by three kinds of cracks
and the museums like it by and they are composed by aqua and park
and i will show now how this is now then first i will talk about the atoms
that are particles composed by quarks and the force between the quarks
as we call the strong nuclear force
what you have from this force is what makes inside the atom the protons
have a attractive force between them that is inside the atomic nucleus is
more intense than the electron electromagnetic force that is here perceived this is the reason that you
have the the parameters inside the atomic nucleus then we have
three kinds of hydrogens that he has the values and the museums
variants are like a protons and neutrons that are composed by three quarks
any museums you have one quark and one and square like the piles
and they will have six kinds of leptons that are the electrons towels
moons and three kinds of neutrinos the fundamental are the electrons
they the most energetic towels then they come for the mules and then
photoelectrons and we have a nutrient associated with each one of them you have the electron
neutrinos you have the tau neutrinos and they move
then you have here the mole that's more energetic than the decay and i elect
them and when they this happens you have neutrinos and nutrients
but it's not sorry some they are in portuguese the presentation then you have six kinds
of leptons have three kinds of families different families that have electrons
removals and towels each one electron have a neutrino associated with him that is electro neutrino the same for the
moon the same frontal then we have six kinds of electrons then for symmetry
it's necessary to have also six kinds of quarks
then i'll not talk about this and the gelman proposed the name quack
from a book of james joyce and this id book you have this this phrase that three quacks from
mr mac they means nothing different then this is name of this
particular and you have six kinds of quarks that you call flavors different flavors
you have strange charming top and bottom
then you'll see the symmetry you have six kinds of laptops and six kinds of
quarks and these 12 fundamental particles are
everything that we have in the universe are composed for these 12
fundamental parts [Music] something very different than we can imagine but then
here you have the charge of your uh of that it's not it's
part of the the charge that you load the electron charge for example
two thirds of the electron charge minus one third of the electric charge
and these are they you see here that have different kinds of energy the most
energetic particles at the top they're in the bottom
then they will imagine that they com they are
responsible for the structure of particles when we have more energy in the universe in the beginning of
generations for example then you can something to illustrate this in size and
see if cameras in size is like we don't have the you can't see like
this but it's only an idea then if you you imagine a size
50 pack something less than
12 uh 10 minus 18 meters
something like this different measure size then i have two kinds of size
it's something that here is only to have idea here you have the flavors and the charge for each
quark and each quark has a month work
you have the up once and ante up down and down charm and charm strange and
strange stop and stop here are there this device
and here are the flavors i have to have each one you have different one but
you have something different also that see they have a characteristic that is like
to charge for the particles that you have they're different you have to charge here but
the quacks has another characteristic here you have how is a neutral a proton
a neutron is composed by a quark up and two quake is down
and the proton is composed by aqua down into
wax up then this is the basic structure of the protons and the mutants until today
maybe they have we're trying to find something that's most fundamental than
this one and also these quarks have charged and also now
he has another characteristic that is color we have three different colors for each
pack it's not is not colors like we imagine is the name that they use but a different properties of these
sparks now then you have a red bluing green and this is something that's minimalic i
don't know if it's correct to work in english because it you need to remember that
a algae particles needed two that are composed by quarks need to be
white because erratic blue green as lights they turn into white lights
then and they also have giant red plenty blue young green then they have colors
with we have quarks and the antiquarks with different kinds of charge and they
are also different kinds of colors then something very different than amazing here you see the three
quacks that's the proton composites they have different colors
then we can image that is like white
and the same thing happens with museums like this then i i'm not
go more and you haven't packed that in this car that's car carrier
and the grooves that that is responsible for the interaction uh
they changed colors these are responsible for the force between the parks
and here you see the protons neutral well that's the
quak and the residual interaction between the quarks
that are responsible to make the protest be together being been here inside the atomic
nucleus but this is part of the is responsible what is responsible for
this force between the gibraltars and neutrals inside the atomic nucleus is
the strongest nuclear force between the quarks and the residual
force that is responsible to make the de proud to be together then we have
four fundamental interactions in universal phenomenal force the gravity the
electromagnetic explains everything that you have here in our words here but when
you go inside the atomic nucleus we have two different two new forces that are
destroyed nuclear force and weak nuclear force this fourth
interactions uh the fundamentals interactions explain that we use to explain everything you
see in the universe here you see likely his you don't force you have gelato magnetic
phosphorus you doing that magnetic force that makes the atoms to
a b in molecules is the same what happens inside the nucleus
the atomic nucleus and something that's very strange when you have uh you try to
find an isolated you need so many energy to do this
with you that is not possible you you have the energy makes that you have
two packs of equals two new pairs of cracks they you didn't find i isolated
a quack until now they at least they are in paris then this is
the important question of when you find a particle excuse me are you a fundamental particle this is the
question that how this differences start to work you will feel elementary part asking all these
and this is the structure of the universe you have you have these 12
kinds of fundamental particles here well the
quarks you have six kinds of packs a quacks and six kinds of philippines
and here you see you have three kinds of families that can image like it is
generation of america the first one down the electron and the neutrino
physical electron neutrino are responsible for the visible matter that you have in the universe
when you have more energies you have this second line here that's the quaksim strange
the new neutrino
we can find in the universe these are the theory that you have here of elementary parts for the fundamental
part okay i try to make a free talk about this i don't know if
i make a it's a very quick presentation and yes i try to to show only that here when now
we're talking universe i have many things different than can imagine that this is possible
through our mothers to explain jamaica as we see
and we measure into universe okay thank you scott thank you so much thank
you marcelo wonderful uh you know i i
you know being that this is of course all invisible to our to our everyday experience you know the
uh the the tiniest levels of the universe are really really strange you know and
uh um you know understanding uh you know
the physics involved in this is also foreign to most of us so
um but uh needless to say it is still all part of our universe and
the largest things in the universe are built up from these things so so there we are including ourselves so
science is fantastic is the most powerful tool that the
the human produces until now that response for our technology that we have in our days
thank you for the quick lesson marcelo thank you
talk just briefly about your um uh your event that you have coming up oh yes
next week on april 22 and 23 we are organizing uh our international mac

caesar brolo and so caesar has been away for a little while but uh
he went to a fantastic star party and he's here to tell us all about it
yes can you hear me because uh yeah i don't know very clear thank you okay
well uh yes scott i returned to the party
grande in mendoza in san rafael mendoza
it's a star party that i i be i i'll be
being the partner of uh jaime garcia from the instituto copernico
um that he live in in ramakaida that is an area of san
rafael mendoza and we made together a necessary party that
it's a myth of a lot of directors and presidents of different
astronomy clubs associations uh nor people that is only amateur but
this time uh la that uh as was this the first uh
the first meet in person uh after the the pandemia was really
really amazing and we was only near to 70 people
but was great because we can watch to each one
again in person to meet the people touch the people you know
it's this is something yes without a screen it's just really magic oh yeah
it's you real yeah and um and well what's really really a nice a
nice meet we had a beautiful night um beautiful
uh people that really we each other to talk uh to talk a lot you
know um the the sensation to to to be
in the place to to talk in in in a real life situation
yes absolutely and for me was it was a shock uh
because i i forget the the the quality of
this skies in san rafael because maybe because it's not in the middle of
the mountain it's not uh it's great because maybe if you need
something you can go to the city and you have a city of two hundred
thousand people but um i
found that science the city have all left and
that have all the illuminations only they have first of all
we are at maybe 20 kilometers from the the city
and the city i don't know why don't work over the sky
like you can suppose and you are in this in a safe area if you need something you know
about healthy or you have a big city really near only a 15 20 minutes
and you have a lot of area of vineyards in
in the area of the ballet jaime garcia is a is a
great producer and he produced their own wine
excellent wine he knows every time more about how to work in wine
and it's a process that because he's astronomer um
it's very interesting that jaime of course that in two weeks more jaime is coming to to the global star party to
talk because he's a member of the aavso
um he was 50 years work
watching and working for the episode um the absolute it's a the episode is a
very important part of of the our meeting in 2010
we were we make a meet uh together
uh with the spring meeting of the episode abso and our autumn star party in in april
um really really well we have we had a lot of fun i have a lot of
pictures to to share with with the audience um i hope that you can
you know enjoy enjoy
the pictures let me
you can see that it's not the presentation if not is the photo viewer of
well this is star party vasa grande april 22 was the one two three
april last two weeks ago this is the institute of
copernicus boys uh is an instituto that jaime garcia founded uh next year uh it
will be the the 50th anniversary anniversary of indigo
pernico and [Music] and we of course we are
making a bigger party um
well here is the picture that i took really the first thing that i i remember
i i thought in adrien brownley our friend
let's say oh i because i was working in the you know that
in this sister party i was all time working thinking if the connection for the telescopes or you know
but um i took some pictures quickly
and all pictures work properly um without
make nothing normally the the dry uh the the level of humidity is only 15
percent and this is why the the place is beautiful to take pictures
this is part of the roof of the hotel
here is a light this is likes are only the likes that are in the in the
who we say dk damn damn
because it's the only likes in in the area where you can found
but we turn off the completely system of illumination of the
of the hotel the the [Music] all completely is is turned off in in
the hotel and in in the in the area of the parks
well you can see that in this picture you can see the
magianic large cloud
is another picture that i took i took only three or four pictures here you can see a much better quality
this is a picture of mariana masino he took she took
this picture and only the light is only the light of you know may we we can't see this
trees in the in the night but you know you have the reflection maybe
of some lines in the distance and it's a beautiful combination where you can see the
large uh magellanic cloud
this is a another picture that i took only 30 30
seconds this is the the area of of uh truth del sur southern cross
um well i don't remember that that that is an amazing milky way carbon is in
spanish but uh
i forget the name in english here is is another part is the roof where we
make observations normally here we make all that is after photography because
it's more easy to connect you know uh connect your computers your telescopes
and in the grass of the park you have all to to make only observations
especially with obsoleans or or if you have a small mount
with your own batteries and a camera is much better go to the to the grass
another picture that i took but without the quality of adrian
bradley of course i i i think all china i think you're gonna have to invite
adrian yes i don't need to go yes need to come here and
enjoy this this is the center of of the milky way and it's only at 45
45 degrees maybe 3 a.m a.m
in the morning this is a picture of uh fernando ricardi
fernando took the area of eta carina nebula
in 30 30 exposures of uh
of two minutes each another picture well this is in the day
before the night of course we prepare all telescope that was for
for uh the all people that say okay i can make astrophotography and here well
casablance richie gretier in another part here you can see the uh we
prepare uh three or four um national geographic that we carry
to the event only for visual we enjoy a lot a lot
this telescope to to use in the night in this skies you know this is the explore scientific
national geographic uh telescopes thank you yeah
you're welcome but what really was amazing
really we enjoy a lot only for visual um we we
use it a lot this telescope of course that we use uh dobsonians too
on a lot of different telescopes to take pictures or or only
watch the sky of course yeah it looks like a very comfortable uh and beautiful
place to have a star party yes absolutely because you can go to your room
and return to use your telescope or go inside of the hotel
without work nothing nothing is is and you have your room
very comfortable and cozy and you know it's
it's very you know sometimes you go to the subparties with with a tent and say okay
i suffer a lot but i love of course for me it's beautiful well here they have a
camp uh special cam very near in the same complex if some people
like to go in in a tent but all people choose the the rooms of course and
it's wonderful to eat and you know the is is is the joke that we
we talked about this isn't about a meeting of astronomy um with the g of
gastronomic astronomy or gastronomy and spanish is is all about food it's the
the business of food you talk gastronomia only the g is
different with between the astronomy and the g yes it's it's
amazing and well this guy um [Music]
making something similar to be a photographer but no um
and this is why this is the the most important uh
uh clouds yes yes of course that is science this
is only to make uh to make uh spectrometry
and this is sure of course yeah yeah
yeah yes at 3 p.m at 3 00 a.m sorry 3 a.m tourism at 3 am
theresa's yes it's like a sandwich choripanis this year my um
my partner in this uh this business uh that is a professional astronomer is eric gonzalez
you know to eric gonzalez uh he couldn't
went to the star party um and i i carry this with a
a maestro a musician specialist and
amateur sermon that is uh luca rocco and he uh
helped me to make a good quality asado with chorizo choripanis you know but
it's only science of course of course of course
this is a beautiful a beautiful picture of centaurus a galaxy that took fernando
riccardini i think that fernando ricardinis is the the
demand that the amateur strummer that more pictures by telescope took
um and he you know sometimes you have the people that work
in the in the store party and say okay i really take pictures and don't only
speak with the people or take pictures of the sky with the camera only because i am
well i sometimes i work but i i work i talk a lot with the friends and you know i
spend all my time talking in the night but we really have so so huge
fun you know you understand it completely but sometimes you say oh you think you took pictures yes
i'm not i have the telescope but i talk a lot with another people you know this is the start that the star parties
really are but
i see the chorizo emission line um diego james uh he said i participated in
the star party valle grande yeah
argentina caesar nomi
i can't even pronounce it yes he told that many many people go to sleep or because
we call to the all people come out 3 a.m yes next year
diego and another ones be uh uh b you need to set an alarm clock
right yes yes yes right yes yes yes yes next year i'll put in the official
program but you know it's something clandestine yes i know but the people sebastian ortero said
all these specials without sharing them yeah yes it's very important
no no no prepare yourselves to just read the comments because i i talk about that
guys i present your pictures tonight in the in the global security yeah so now yes and
they are talking yes i know that if you yes i told him i told them to say if you
need to talk something you can put comments in the web no problem and they are
yes of course yes don't mostly about not being able to be afraid about the charismas because
next year you can you can enjoy again yeah
yes sure sure and this is well this is sebastiano tero talking
and this is part of the talks that we will really enjoy the talks because
and sebastian is a genius to just playing and really we are happy to have
in a global star party to sebastian because it's a great a great
professional about variable star uh uh about variable stars sorry
um really uh and he's really very fun
about um how is playing and it's very important too and he's he's a
bit watcher now uh he's a genius about it's a genius about bill watching uh
here well uh i i remember the names uh
martin de leches pablo barrios [Music]
and here is uh well i don't remember the name now but
this is my friend juice it's uh it's from catamarca i
i remember later the name um
well here it's me with uh santiago with uh alejandro vareli we are we was talking about
optics in astronomy especially about the beliefs about how telescopic
you know um what's more about belief that that they believe
uh that the people believe about about optics in astronomy of for example scott
when you receive the the the comments from the people say okay i have
uh something to to uh to clean in my optics because this
this can be in my pictures and we talk about this right oh yeah like you believe about
being on the lens or something like that yes it's something that you can arm
absolutely absolutely right yes that's absolutely not true but
and uh was it a very nice thing to to share to the people the
people you know asked us about this belief or something that all people say ah yes
it's real i believe that very very nice myths and another surprise about
optics this is what all this the the the
uh the team of uh uh mesa vital cosmos that are working
well i'm working with them about the they come the restoration of the
the observatory solar observatory in san miguel
here is jaime garcia in his talk about his uh 50 years
watching variable star this very was very interesting
for me was a surprise it's a highly incredible 50 years was a attack
because we were talking you know about about organization and when i was in in
in his talk about the was amazing really
uh claudia martinez talked about after tourism a business for
that the people can carry or can uh make for for carry people and go to see the stars
you know is something that is in argentina and chile well everywhere the people go to see the stars and talk
about you know the myths the the it's very interesting and it's it's a
it's a growing business in in argentina because we have a lot of skies really
dark um here were more types more talks i was
really interested in noted about variable stars
uh um well i talked about about the when it started you know the meet the
meeting that was talking about with uh jaime garcia jaime
garcia is going to to to appear in global safari i told
i told him that you know to go to to be in global safari

talks in the night when the people uh feel something freeze about the
you know the weather you you you feel cold you can go to the
clandestine talks that is a it's a tradition in our third party
inside the lobby and you
talking in the entire talk the entire night about physics and astronomy you
know it's very very nice and the people carry a coffee
enjoy the talk and return to their telescope it's very nice very nice
yeah we really enjoyed that a lot of talk
uh sorry federico garcia the jaime garcia sons it's actually
a professional astronomer too his work he was working in

a a a a little ship a boat that you can you can get uh
traveling miguel me ah no it's not bigger

it's a amazing place too and well here we are all together
and uh you know the the group the picture of
the group um we enjoy a lot and of course all
one are invited especially in the people from the global star party we are
uh awaiting you for next year in april we can get a lot of uh we are going to
make a a bigger surprise because this year was only
for for start before the pandemic situation and
next year we can return to the our normal numbers over 100 people in argentina is
is a great number for for eu we can't compare for for another third parties
but we are really people that when with their telescope um
really they're they're really interested in enjoying astronomy and this is
beautiful and well this is my presentation about the thank you
party thank you cesar you'll have to you'll have to give
some more information uh about uh uh the next year's star party i
don't know if the dates already do you already know the dates for next year uh i don't know because um
we need to to talk normally we have the the the
the time in maybe this year in october we have we have
ready the the exactly days because we take the entire hotel for us because if
not this is something that first of all we need the hotel entirely for us
um because if you have another people in the hotel
it's really people suffer us and it's not so good but um
but um when we have the the the the time for from the hotel we say okay
you know um it's not a full moon of course it's it's
a new moon and normally is is in april because it's it's a great time
for for uh you know for uh have a grey
race a situation of weather we had an excellent weather very very
dry very you know it's it's very important uh have first
of all you can see the transparency of the sky from the photographs so it's yes
it's very easy and especially yeah and especially doing observations
where you have the the the the the grey difference with the another
skies we we have in in our farm area buenos aires very dark skies but the problem is that
many times the humid uh make a scattering and you have the
very the the milky way is not so bright like a problem i have in arkansas many
times you know it can be yes very very dark um but you have 60 percent of humid it's
not too much but you have absorption of of uh yeah of life that's right
that's absolutely right so yeah only occasionally we get uh really
clear transparent skies you know and those we really treasure here in in
in arkansas so um which is why we are going down to texas uh for the eclipses you know and
so um you know because we have a better chance for uh transparent sky down there clear
sky yes yes we'll have to learn more about it uh uh
you know certainly i want to get down to argentina for one reason or another uh to come and see you uh cesar and
maybe we can get maxie and all of our friends together at some event that would be great so yeah yes we needed to
maxi in this third party next year i told to maxie that he really need to go
to to san rafael mendoza yes sounds great
all right well thank you very much caesar for everyone yeah we're going to bring them
yeah everybody can come right that's right that's right now uh first vegetarians do
they have vegetarian chorizo in uh in argentina or no
it's something like to see an ufo or i don't know i never seen that
right okay no i don't know well we can make something for for everyone yes no
problem we can make a tough week we can make it barbecue or no but i i make a
barbecue with vegetables very good if some people told me yes i need us another thing i am vegetarian yes i can
make the that for for the people that don't eat meat absolutely great awesome
awesome so maxie are you ready to come on tonight
maybe he's getting us uh chorizo himself yes is the time with martin the time
come on maxi yeah yeah
yeah maxi maybe he had to be called away i'm not sure no yes sometimes when you are
a white team and yes i can go i can go to
something right yeah yes but but it's something that for everyone
in our server parties but this is real that we have 90
third parties i know we've done 90 star parties you've been
on many many of them i think with the exception of the first few i
think you've been on almost all of them seasons yes and the last ones but maybe no more two or three
right yes i have i have a record
do you need me yeah yeah yes absolutely so let's see if i can find maxi here
yeah yes let's see
i'm calling maxie excellent yes i i sent him an uh yes excellent idea yes
it's a great thing of global safari the people knows that we are really
and it's really live yes yes and scott in our
it's in our um after parties we i remember the day that
we we talked we finished the talk at 4 00 a.m
it's the same that in real life it's very late yeah yeah
yeah i know so no maxi no maxi
um did not occur this year because they closed it because of the the three
well no it went this way okay they they had they had um
uh they had gotten approval to actually uh operate the nif event at the
auditorium where they normally go but uh because it's a very international
type of event so you have a lot of international um
vendors that show up for this celestron had
had decided that not come okay because it was still kind of early we were seeing a spike in um
uh you know coveted cases and this kind of thing so they decided you know let's play it safe
and uh there was a couple others that decided to say let's play it safe as well i'll say no oh my god yeah yeah and
so they just go unless i mean these vendors cannot come or
uh have decided not to come and um so you know they felt that they made the
right decision and and the people there's maxie maxie
there's not enough participants they decided not to have it this year and to do it next year so but this is
this is very bad for the small smaller you know small expositors that
they lost the opportunity for for show their equipment you know oh yeah i think
that sometimes well i hope that next year um and i'm very very interested in visit
you and of course i can offer me to to work free
and talk with the people in in the explore scientific stand if maxi say yes
we can carry the maxi too yes i i agree
here i'm gonna post something in the uh this is from diego and he's writing to you caesar so
i put it in the chat
uh of course yes yes yes diego diego i have a picture of diego working he's a
his teacher and really is he's a great a great and young
amateur astronomer and educator it's it's really yes yes
we can invite him if he talk i think that he taught in english i don't know but i never told him about
but it's a it's a great education great great people great people really awesome
awesome yeah all right well maxie you've got the stage here so we're going to turn this over to you
but yes thank you for coming on no thank you sorry if i didn't answer i i figured you were
getting a chorizo or something so no
it's another kind of yes i know it's beef with bread uh
fried and you know and with a potato
breaded meat is in english i don't know braided meat or maybe i don't know
milanese that exists in the united states yes yes so well thank you scott for inviting me
i was enjoying the the girl supported what i what i could
get and here uh well the last a week
i was doing some live views from my home and i left
my gear taking pictures almost to 4 am and i went and i remember wake up to get
all inside but i saw the the the great conjunction of a
saturn and mars nearby and of course
venus and it was pretty amazing yeah so
let me and let's close this
okay let me share my screen okay so
uh i was capturing last week some deep sky objects
that i was a well basically
appointed and doing maybe pictures of one hour or a couple more
for example we have here this you can see here's a star
but behind of this star is a nebulosity
let me stretch it this is the butterfly
nebula i think that is caused in stellarium
i this is only the stacked version because i didn't process this you can see i have black
places and bright in places but i have to clear
this up but i think it was almost of one hour but
this a nebulosity reminds me the carinae because
you have the what the eta carinae star
illuminating the all the nebulosity and but this is a
lonely nebula looks like but here we have a a galaxy
it's pretty far away here uh there's another one
small so then i went to ngc 4945
and this is what i get this is the final processing let me put it more
oh wow now which which galaxy is this this is ngc
4945 is in centaurus
nearby the omega centauri and centaurus a this galaxy you can watch it with the
telescopes and it's and it's a really good place to take pictures
well we have here another kind of galaxies really far away
here there's another one here's on another one and
here behind this star we have this one
it looks like the the dartmouth and excel mostly
but all these objects i think they are a pgc catalog
but nearby this galaxy there's another one it's a lenticular galaxy it's
a more brightness but it doesn't have too much shape
like this one you have here the core the clouds the stars and the dust
yeah this is an amazing place to to take pictures i think a couple
weeks ago [Music] the apod of nasa
published a one of this place of course doesn't mind but
it was amazing too so then i also
do this place this is a in
the dragons of era or dragon and this is in
in the other constellation and [Music] well here we have a lot of
stars and nebulosity but of course this is a good place to
to take pictures in narrow brand filters but i don't have it i only do
color when i have a color camera but i hope one day maybe i can
[Music] go there i think i i had to reprocess this because i
i think i i went too far with the colors and you know
the shape it is i like it too but i i there's something that i don't
don't feel the it matches i i don't know what but
this is uh the the another phase of do astrophotography you
know and and sometimes you ask ask yourself
this is a what's it looks like or this is a i i did a bad lies for bad soaps
or maybe the calibration it wasn't good and all those and all the processing it
wasn't good and i know that
things uh makes you reprocess and reprocess and check again and
and practicing again and everything and now you can see some of the craziness of being an astrophotographer
exactly they're never satisfied they always want to do better which which is what drives
them uh and uh you know maxie earlier david eicher showed your uh
omega centauri image uh that globular cluster is so beautiful
david if you follow him on facebook you'll notice that he shows really only some of
the finest astrophotography made so for him to stop his program and to show
your globular star cluster image is quite a statement i think so and it was beautiful it was a beautiful
image thank you and thank you david for for sharing here in the gsp uh oh it was i i
sent it to all of you here in the in the gsp uh
for a little gift because they believe a
did a poem a of this global cluster and of course it was like oh let's
let's put it together at the same time so
well the another object that i did it was a nearby the caribbean
but this is an open cluster this is a really one good one
you have there's a lot of stars when you see it through the
telescope here it's amazing to to watch all the
the the shining stars yeah
yeah and and the background you know that's a lot of stars it
looks like a m7 level cluster but uh
in this case this place calls uh yes ngc 3532
you know this is a single picture and the final result is
this i think it was only one hour because
there are stars they're really writing
but uh this is a really good global a open cluster to
to capture to a watch through telescope if you had a dobsonian
if you have a good well or even with small a telescope uh
refractors and well i i i
use sometimes my maxwell tool and it fits really good here
and of course it's amazing to to watch it so
a couple days ago i went with my girlfriend to adverti to spend
a some sun in sunday no sorry it was the saturday afternoon
and we've been i i did some pictures like adrian does
you know i was taking pictures to bears paradise you know in this case it was the
the sun behind the tree of course my my dog sophie
i'm sorry [Music] that trophy and of course was i was taking pictures to
some pidgeots you know we have autumns uh leaves or fall leaves
is getting yellow and
this is a without processing we have the the raw files
uh but what i did also i was trying to capture
for example we have the moon and i think it was evented
it's a bird that sings pretty pretty loud
uh i think what what it was what i process
i think it was this or not no this is the moon
another moon well i was manually trying to to capture some
birds and ah here this is one
we call davinteve i don't know if
you in the united states have this bird it's a particularly it's
in everywhere here and it's the things of this bird is particularly
like the name bente something like that it's a beautiful
shot i love that with the moon yeah of course the moon will be out of focus because the
the the bird on the tree was nearby me and this steve with the [Music]
uh a 270 millimeters a
lens and the nikon and of course i
i just i did this with the moon i
posted on my instagram page here's the blurred
leaves but it gets focused to the to the moon
and uh to do some kind of autumn pictures
from here and of course i have some treats to the west we can hear we can see
a people the the shadow of people there and the sun and goings down
through the the streets i was shutting this place and there was people playing
football soccer and they are passing by
but you know it was pretty good to to capture this
that's cool like a stonehenge something yeah but with trees
and freehand yes i i do this is almost beautiful
beautiful maxi yeah it's really amazing amazing really
i is why we need to to give you to have you next year
in our star party actually you can make magic maxi wow look that
maybe you you get a green green green flash yeah i think you're saying
yeah yeah sure come on and well thank you assistant
well here is it's going down pretty low and
i think in this one i up again you can see this tree and some crops
on the field uh because to a this is in the border of alberti this
is a really good place to to be uh because it has a lake
also parisia's place to it's a a good park for his sophie again
sophie is living in your bed right now
get the permission for for sophie yeah i know [Laughter]
well this is not grass this is the lake and
it's full of this plant uh that floats in the water yeah
yeah and this bird's got here's the bottle that's the shame but
this verse goes to here and play and sit
and i think i shot this one here
there's another one
we have a number of uh amateur astronomers that are also photographing making nice photographs of birds yeah so
we'll have to have a lot about that
it's a problem no it's a problem they're loud yeah yes a lot yes yes
they're everywhere yeah yes good
so well he's my girlfriend with sophie playing with a stick
so let me ask you guys something is it is it legal to buy a parrot in argentina
can you uh not this kind of parrot because no anybody
they love this parade because it's a huge number but it's a play
but the another ones from the north are completely illegal absolutely
completely yes from the rainforest parrots are completely illegal
yeah all kind of of uh and really is incredible that here the
the controls are very very exhaustive because
um existed a lot of a huge illegal commerce
in the past but now is is really you know but
first of all i think that if if you if you when if you carry a
beer exotic beer to your home your kids tell you why
because the education today about animals about the extinction of the
species yes i i i think that the people watch
in a very very bad way
i forget the name of of haul maxi in english okay because the cage a case with beer
i remember yes today few only i don't know if excess people
with cage with birds in a cage because in the past my my my grandfathers have a
big cage with a lot of different beards because it was normal but today i think
that today is something that and all comers of beards and actually the exact exact exotic species
i think this is something that is very bad and especially the kids
hey this is incredible and it's great because that's good that's good it's good yes but everywhere yes and uh so
because they inherit all that we um that we that we did and good and bad you know
don't have yes don't have more sense in today because you can get the camera and
you know here in the i we have a
a what we call a like a grandma but it wasn't my grandma
that she lives in besides my square and she has a parrot you know and but
she does she doesn't have it in a cage it was in a in a way in a ladder
lyrics yes is it what's the best yes if you in the past yes it's got but this is
what's different because it was a local parrot from the pampas the the same god
and you have uh you you can yes in the past yes like grandmothers or
they have yes and the most the most funny thing in the united states i was i think that was
the same the the partner that told some words and especially
explicit yes i love that in my childhood i
remember you know like i can say
my my father told me sometimes that
his great a grandfather has a parrot that
always say to the dog that they they have a shera
and the dog say [Music]
yeah but well guys i i think i had to go to bed
yes i hope this short presentation was uh
it's great it was an amazing 1990 global sub party yeah thank you so much
thanks everybody i think that uh it was we had some new people on that was uh
very interesting of course to all of us but it's always great to be back with old friends and
and we'll do it again next tuesday for the 91st global star party
and uh the with the theme of stellar streams we've talked about it a little bit on this program and you saw some
a little bit of imagery that would hint at that but uh of course there's many meeting meanings to the
uh you know the our themes and uh it's all meant to
be talked about from the different uh perspectives and lenses of our presenters so
um until that time you guys take care keep looking up uh
we are we'll sign out now and i hope to see you back next tuesday
night take care [Music]
