Istg ur turning more into a cat with every message 😭

[delicate lance]

for reference the mono setup wouldnt be that much later

i have a defect goto exos-2 which i will repair and then an HEQ5 to sell

so about 1.200 EUR i can get from selling em, which funds the 10'' and starts on the mono

Yeah no, i have enough group chats as it is

[brisk copper]

you wanted to join bruh 😭

What kind of rave doesn’t have bright lights?

[swift heart]

An astro rave.

[urban quiver]

Stupid

[hybrid echo]

this but its also one of those silent raves so its just a star party
and maybe

[restive fiber]

The guy who talks about Linux will give you tips on how to use it

[zealous cloak]

[cold moon]

Blasphemy

PNe are the best.

After galaxies of course

[devout tinsel]

Nah, they are too small

[cold moon]

Short focal distance problems 🥀

[rain void]

More like living on a planet with an atmosphere problems

[stone zealot]

Lucky imaging exists🙏

[summer turret]

naw hungry people gotta see cool stuff in space first

[undone sinew]

i think they might have bigger problems first

[stone zealot]

I think they should eat so they dont have that problem (jk im donating to the hungry people)

[ivory mural]

ok so how crazy is this dream telescope setup

there's gotta be a point where the telescope contributes more to society than ending world hunger

[desert obsidian]

Hehehe

Refractors hehe

[urban quiver]

Every reflector owner is just jealous of refractors

It’s just life

[desert obsidian]

Every refractor user

Has a refractor

[hybrid echo]

why would i be jealous of not being able to image stuff

[swift heart]

Why would I be jealous of having less resolving power to work with

[violet dagger]

dream telescope setup obviously

[obsidian plover]

CDK1000 under bortle 1 skies with adaptive optics

[obsidian plover]

One of the blobs resolved with my redcat51

[cerulean elm]

Said by every refractor owner to justify its small aperture

[stone zealot]

Nahh im enjoying the 130mm of pure light

[hybrid echo]

this guy think 130mm is big

[cerulean elm]

It is bigger than the average frac

And a fraction of its price as well

[stone zealot]

Dont bring that stuff in this convo

[stone zealot]

Fr

[hybrid echo]

thats really not saying much lmao

[ivory mural]

refractors are only good if you want less than 400mm focal length

past that you can get a fast newt

[cerulean elm]

[zealous cloak]

Let me have 300mm of aperture just to have 70% of it obstructed

[cerulean elm]

A 250mm RC has a CO of 110mm. That's 20% obstruction

The secondary mirror is bigger than a frac

[zealous cloak]

Ever heard of exaggerations

[cerulean elm]

It wasn't exaggerated enough

[static sapphire]

Obligatory redcat pillars

[undone sinew]

redcats are overrated

[cerulean elm]

Where's the blob?

[zealous cloak]

@static sapphire show him the uncropped

[static sapphire]

His mind cannot comprehend

[undone sinew]

show me

[zealous cloak]

[undone sinew]

i stand corrected

Actually should i get a redcat 51 would it be better than an askar 71f

[young quail]

That was with redcat?

[static sapphire]

Yes RedCat 51 w/ asi294mm

Which is a 4/3rds sensor

So crop factor 2

[young quail]

Thats a really great pic, redcat be putting in work

[static sapphire]

I got lucky with a really good example but they’re quite great in general

I can only speak to the 51 because that’s what I have

[undone sinew]

Yknow what we’re in the polls thread so whatever

[static sapphire]

I think this depends a bit on your camera and targets you want to shoot

I bought everything together and did quite a lot of research before I did

I wanted some super portable yet high resolution with enough leeway to do small crops

so obviously mono and small pixels, but it's just oversampling with the redcat

[undone sinew]

IMX533 (mono) and i would wanna image most of the large emission nebulae

But i dont really care about getting the whole nebula in the frame

[static sapphire]

imo the 533 is better suited to focal lengths that are a bit longer

i'd throw the telescopes and camera into telescopius and try to see how you like framing and how bad undersampling is

@undone sinew ^

[undone sinew]

Wait the redcat focal length is only 250mm?

Astronomy tools is giving me this

Actually i forgot its 3.76 not 3

So its even worse

i mean i could swap the camera with an imx585 but i really dont like its frame

[static sapphire]

yeah the askar is basically twice the FL of the redcat

I personally wouldn't want to use the askar because it's quite a bit slower

but again my requirements might be different from yours

unfortunately the perfect telescope which does everything doesn't exist 😄

[urban quiver]

I have the Askar 71f, and 533mc

It’s a great combo

I love the FOV, allows me to do nebulas and a lot of galaxies

Here’s a raw stack, only auto stretch of my latest target, 4.4 hours.

[urban quiver]

A nice refractor, a nice refractor, and another nice refractor is all you need

3 refractors all you could ever ask for

[glacial bear]

Heretic.

[urban quiver]

Nah fr tho, a 6-10” dob, a good refractor, and I’d say even a reflector

Good for visual, wide field imaging, and some long focal length imaging

[glacial bear]

Other than the size of the dob, I'll agree.

[urban quiver]

What would you say then

[glacial bear]

I'm biased to planetary right now so 16-24"

[urban quiver]

I have a 6”, and don’t need anything bigger since I primarily image, anything over 10” starts getting really large and not feasible for many people

[urban quiver]

I can’t imagine the pain having a 24” DOB would be

[glacial bear]

I have an 8" Newt, another 6" Newt, and an EvoStar 72ED

Oh and a 70mm Gskyer econo-scope

[glacial bear]

24" would require its own house, let's be serious

[supple wraith]

I have 4 scopes all for different uses.

[glacial bear]

Oh sure, throw the poll question off sheesh. 😆

[quasi cedar]

only zwo item i own is an astrocam but the amount of accessories they have and how expensive they are is crazy, so im gonna go with that one

[mint talon]

those are all the things i like about zwo though

[stone zealot]

Average modded 130PDS pillars

[cerulean elm]

As another average heavily moded 130PDS, that could have been sharper sir

[stone zealot]

I have an old CCD camera with large pixels what do you expect

[cerulean elm]

Fair.

[stone zealot]

Yeah, but still sharp and full of detail for a modded 130PDS, glued the primary mirror to remove the clips, and a modded secondary holder

[cerulean elm]

I used a mirror mask to hide the clips and a CNC spider. Chopped down the focuser draw tube so ot doesn't stick into the light path anymore and truck load of flocking

[stone zealot]

Nice, i had an option to put on a primary mask but i will lose some of the mirror surface making it less efficent, every photon counts.

[cerulean elm]

It's insignificant really😅 .
So if the 130PDS is f5, with a mirror mask it would be like f4.8, f4.9. Not big of a difference

[stone zealot]

Yeah but still i like more efficency, but still it was worth it and my stars are so sharp. I have an autofocuser i just need to make a holder for it

[cerulean elm]

Didn't your EAF come with a mounting bracket?

[stone zealot]

Its a home made EAF, its like a stepper motor with the gears... and a stepper controler

[cerulean elm]

Oh, that's pretty neat. I'm assuming you're using it via Arduino ASCOM?

[stone zealot]

Actually i dont know my friend gave it to me as a gift, he just said to plug it in and connect it via NINA

[cerulean elm]

Sounds like my automatic dew heater. Just plug it in... don't worry how it works or what drives it needs.

[stone zealot]

Nice, cant wait to try it out

[cerulean elm]

The EAF is gonna be a bigger upgrade than the mirror mask and spider

[supple wraith]

I don’t think I’d have much trouble carrying a 12” ota, especially if it’s just a newt. Those are pretty light.

[urban quiver]

hard in what way

mentally? physically? in terms of equipment use? processing?

[vagrant basin]

Everything

As a whole

[deep mesa]

Interesting for me to see how a science based community answers this question

[proud quarry]

Often. I spent several weeks when I started just trying to get the software to work

I am also way overly critical of what I do, and doubt myself a lot

[ivory mural]

same

[proud quarry]

It sucks doesn't it

[static sapphire]

Fwiw some organized religions do a lot of astronomy; one of the most popular guides (“Turn Left at Orion”) was written by the Vatican Astronomer. And yes it’s kind of a weird dichotomy, especially considering some of the history with Galileo etc.

[urban quiver]

Fun fact, the Vatican believes God and the Big Bang are compatible 🙂

And iirc the Big Bang Theory was formulated by a Catholic Priest

[rain void]

[stone zealot]

Reading more into it made more sense to me

[stone zealot]

Also Isaac Newton and Kepler believed in God too.

[vagrant basin]

I was doing the same thing i had to strip down my new mount and replace some bearings it was so much physical strain and when i finished and tested it my dec slew just gave up😭

[cold moon]

I'm strictly NOT religious, meaning I don't follow religions, but I do not deny or believe in God, I'm agnostic in that case

I feel it's the only intellectually honest position one could have

jm so bored man

[rain void]

Astrograph superiority

Impossible to do visual

[cerulean elm]

Visual is full of lies

[undone sinew]

Ironic considering most of astrophotography is false color

[cerulean elm]

Which one is easier to prove. I saw something weird while I was looking trough the telescope vs hey, this is something weird that I imaged

[rain void]

I see canals on Mars, just trust me bro

[cerulean elm]

Dude, I saw a star dissappear near Polaris! You gotta belive me

[devout tinsel]

I only do visual when the sky is mostly in clouds

[glacial bear]

Biggest challenge for me is not having clear skies and good atmosphere for months now.

Still haven't set up my Onstep so I can't speak for how easy it is to use that, which means I haven't had a chance to try DSO yet and I know from trying to work with my comet image that processing DSO might be at the very least a substantial instructional curve.

[undone sinew]

months??

[cerulean elm]

That's the beauty of this hobby. The challenge. Pushing your limits and your equipment limits. Sometimes everything goes right, and other times it goes up in flames. Every failure is a lesson that paves a road to better skills

[vagrant basin]

I feel for you bro

[glacial bear]

Voting "no" on the grounds that "Religious" conveys, in my mind, going to church and actively participating in ceremonial stuff with folks who like to play like they're good people for an hour once a week.

Do I have faith in a Divine Creator and Savior? Yes, absolutely. Do I have thoughts about how things came about? Also, yes. Do I want to get into a discussion of if Adam had a bellybutton (in a metaphorical manner)? Nope not at all.

[vagrant basin]

In the end its very worth like creating a master piece from your struggles and effort

[glacial bear]

& @vagrant basin yeah, pretty much. Cloudy and right now getting smoked out by the stuff from the wildfires in Canada and probably California and Grand Canyon. Monday and Tuesday were BAD for air quality ... sun and moon were f'n red.

[undone sinew]

the moon was also really red last night for some reason but i dont live near any wildfires so idk

[vagrant basin]

I remember some fire a year ago in the us and it reached uk's atmosphere the moon was super red

[undone sinew]

im bored what do i even do

i ran out of shitty poll ideas

[glacial bear]

Historically I think there's a component of the Roman church wanting to obtain/maintain power and one way to do that is control information. There were a few other things at play that involved the culture and attitudes to religion, especially the Roman Church and the Pope, that are much different than today.

[cerulean elm]

Lots of people start and give up in this hobby just because they don't put the effort to learn how the equipment works.
Most people have the expectation that this hobby is just point up and shoot 1,2 and it's done. It takes a lot of patience. If if you don't have the will for it... then just search pretty pictures on the internet😂

[undone sinew]

Imma think of one

Hmm

[deep mesa]

get altair on there asap

🔥

[undone sinew]

I just asked ai for the list cause i only know like 2 brands

[deep mesa]

smh

[static sapphire]

Totally. Fwiw I don’t have a religious bone in my body. I think most people who are overtly religious (as in rubbing it into others people’s faces) aren’t really adhering to what their own religion teaches. ¯_(ツ)_/¯

[deep mesa]

zwo, player one, qhy, svbony, ogma, touptek, altair, im probably forgetting a bunch

risingcam bur that’s basically touptek

[cerulean elm]

Isn't Altair re-branded Touptek?

[deep mesa]

yea…

but like

altair

[undone sinew]

shit i forgot touptek

[desert obsidian]

Moravian Instruments

[cerulean elm]

[rain void]

As in always not astrodark, or not always astrodark?

[sharp storm]

As in never astrodark

[rain void]

Well it depends on how dark then

[sharp storm]

Should have rephrased it

Thx

[sharp storm]

Like 55° north during summer type of dark

[rain void]

Uhh

Sooo... 11.5 degrees below horizon?

[restive fiber]

What is astro dark?

[marble hearth]

time period when the sun is lower than a certain altitude

aka when 'night' starts for astronomers, and its easiest to see the dimmer stars

[marble hearth]

18 degrees or more below horizon^^

[undone sinew]

What is astrodark

[swift heart]

Anyone with a 6" RC is being left out of this poll lmao

[rain void]

Rounded to nearest integer maybe?

Wait f9 is still gone lmao

[undone sinew]

shit

Whatever im sure nobody has an f/9

Mani wish you could edit polls

[sharp storm]

Yep

[rain void]

hmm... Idk how much sky illumination that is, but your question can be answered pretty objectively

[sharp storm]

I guess the choice is obvious

[rain void]

I honestly wouldn't be surprised if the sky is brighter with the full moon, tho it has the advantage of being able to get far more time because nights will be short

[cold moon]

A full mun is definitely brighter than nautical darkness

If that's what you mean with no astronomical darkness

[rain void]

mun

[cold moon]

Sorry I was in the Kerbal system for a moment

[late summit]

I landed on minmus for the first time earlier today

had to set myself on a crash course because I couldn't for the life of me actually get in orbit

Did the good old "Point at target and hope for the best"

[undone sinew]

Why are you all merging

i need.. new…. Poll.. ideap

[late summit]

Same thing happened to me lol

[undone sinew]

hmm… what do astrophotograpers like

The correct answer: it depends on the target

[brisk copper]

3 different ir wavelength false colour is best

[mint talon]

[hybrid echo]

your basic sho filters disgust me

[delicate lance]

HSS

[zealous cloak]

[swift heart]

Bro can only see supernova remnants

[brisk copper]

me when someone hasnt heard of buying directly from the factory

[zealous cloak]

Why so pressed guys

[swift heart]

instructions unclear, I bought americium directly from the factory and now the Nuclear Regulatory Commission is hunting me down

[rain void]

i need to kill someone

i'm the ONLY ONE to answer SHO

[cedar dome]

HaRGB is the only image I’ve done, but SHO looks nice in my eyes

[rain void]

anyways...

i have an important poll to make

[mint talon]

idk

[ivory mural]

a lot

[mint talon]

depends on the target

[proud quarry]

Thats too much technicality that I don't fully understand yet :D

[ivory mural]

i value my sharpness

[rain void]

each frame here is a doubling in SNR

[ivory mural]

if image half as sharp how many times more snr until you okay with the tradeoff

[ivory mural]

12 times

[proud quarry]

Oh right

[rain void]

damn

[brisk copper]

meow meow, mroow, mrrp, nya mew~ mewo!!!

[ivory mural]

maybe more

[rain void]

that's like the difference between the first and the fith frame in my vid tho

[ivory mural]

i know

i just think an image that isnt sharp looks bland

and to make up for it youd need a lot of dust

[brisk copper]

to cover the sorrow!!!

[rain void]

wait no it's much more

it's the difference between the first and the last frame

that's a factor of 16 at least

[rain void]

you're high on cope and i intend to prove it

[ivory mural]

?

vro where is the cope

you asked how much i value sharpness

thats how much i value it

[rain void]

ik but i'm making a comparison

just wait a sec

[ivory mural]

and like bob said, it depends on the target

[rain void]

ofc, but i'm just looking for a ballpark

[ivory mural]

in here id value sharpness a lot less bc its some wispy nebulae

[rain void]

counterpoint

[ivory mural]

?

[rain void]

you think those are equal quality?

crop

i convolved the full stack to get exactly twice the fwhm of a single sub

and it's 1 sub vs 309 subs, meaning snr should be at most sqrt(309) = 17.578 times greater

i even chose one of the best single subs, so i figured the difference is probably around 16x

[brisk copper]

righ bete

[rain void]

?

[brisk copper]

stars aren't as bloated

[rain void]

yeah ofc, it's exactly a factor of 2 on the fwhm

[brisk copper]

also im in b&w so i cant see colour rn

[rain void]

well you're in luck, cause the image is mono Hα

[ivory mural]

no, i said before you sent that that i wouldnt

[brisk copper]

o lol

[ivory mural]

it depends on the target

[rain void]

that's fair, but 12 or more still sounds drastic

[ivory mural]

on this target i value sharpness a lot less since sharpness isnt gaining you much

[brisk copper]

depends on the meowget

[ivory mural]

yse

[rain void]

and i specifically mean at a point where SNR isn't already so high, that you can't tell the difference

so whispy nebulae should be a prime example

ofc i would also sacrifice a lot of SNR on a target like m42 core, where the SNR quickly gets to a point where it's almost perfect

like 20 min vs 200 hours on m42 core probably looks the same lmao

[ivory mural]

i dont think its a good example because it doesnt benefit very much from sharpness

[sudden locust]

What is an SNR?

[brisk copper]

m42 core is meant to be lucky imaged, prove me wrong

[rain void]

https://tenor.com/view/amen-gif-23345354

[ivory mural]

something like m51 that has both dim bits and benefits a lot from sharpness would be a better example imo

[rain void]

that's actually a good point

sharpness probably matters a lot more for galaxies than nebulae

[ivory mural]

if they did, i dont think they wouldve cared much

we would probably be like random dumb species #12932

[glacial bear]

What about those folks who have more than one telescope?

[summer turret]

your favourite telescope

[cerulean elm]

Those are so OP! I saw the Einstein's Cross with this

[ivory mural]

TWO DOLLARS OFF

[undone sinew]

one time i saw one of these telescopes for sale and the packaging that usually has an image of the moon on it was advertising being able to look at the dark side of the moon

[restive fiber]

welp, it is going to end anyway

[sudden locust]

Why is the Ritchey-Chrétien not included in the "Reflector" category?

[undone sinew]

because i knew there was gonna be at least one person thats’s gonna say “hey why didnt you put rct in the poll”

[cerulean elm]

Instead of Reflector, you should have put Newtonian. You covered RC, SCT and MAK

[sudden locust]

Why would there be? As it is a reflecting telescope, it should be included in the "Reflector" category as well.

[cedar dome]

I thought SCT’s and MAK’s were considered Catadioptric, and RC and things in that nature were considered reflectors (some people call them cassegrain style reflectors :/ )

[sudden locust]

Correct.

[cedar dome]

Hooray

[cold moon]

Yes, Cassegrain just means that the secondary bounces the light back at the primary basically

So most of the times the primary has to have a hole

[cedar dome]

I see

[cerulean elm]

I understand why people simply call them Cassegrain.
The difference between a mak and an SCT is the corrector plate. The RC doesn't have a corrector plate. So all of them are Cassegrains because the secondary mirror bounces the light back at the primary mirror

[rain void]

RASA

[cerulean elm]

All of them are a simple parabolic + hyperbolic mirror configuration

[cerulean elm]

Schmidt camera

[restive fiber]

What do you call a telescope that has no mirrors nor lenses?

[cerulean elm]

Hydraulic cylinder

[cerulean elm]

.

[cold moon]

Just for clarification, they bounce it in the direction of the primary but the primary doesn't interact with it of course

[cerulean elm]

Well yes I know. But the principle between all of them is the same

[cerulean elm]

What kind of design would be Vera Rubin tho?

[cold moon]

Similar to a paul baker, so a TMA I guess?

Paul-Baker/Mersenne-Schmidt from the wikipedia page

[cerulean elm]

Now that's a design to talk about

hows the black hole nebula designated

havent heard of it

its a thickass cloud of dust, lynds dark nebulae 329

[zealous cloak]

so a random dark nebula in the mw core, cool

[hybrid echo]

ye
im hoping to poke thru it with ir

[brisk copper]

poke a hole in it

where colour

[hybrid echo]

its LBN obviously

[undone sinew]

bro who the hell is lynds

legit have never heard about this catalog

[hybrid echo]

bro he is based
He also made LDN
For all the dark nebulae

[undone sinew]

barnard catalog is better

for dark nebulae

actually the better word is more documented

since like 98% of all ldn objects dont even have a wikipedia page

[hybrid echo]

nah
See thats where he gets you
Cause lbn, for bright nebulae
Is also mostly dark nebulae
Its a troll

[undone sinew]

bro why did he name it like that then

its like the complete polar opposite

[hybrid echo]

he ran out of space in ldn so he had to put some of them in lbn there were just too many

[cold moon]

I'm sorry but where is the Atlas of peculiar galaxies?

[fading flower]

Wheres arp?

[undone sinew]

istg if another person is gonna tell me that i forgot to put some obscure ass catalog made in the 6th century im gonna lose it

[desert obsidian]

Bbut arp is peak

[cold moon]

The Arp catalogue is peak

It's relatively recent

Made in 1966

[cerulean elm]

Where's Abell?

[sudden locust]

Where is PGC?

[hybrid echo]

you know im thinking we really need ugc too tho

[cerulean elm]

Where is UGC?

[cold moon]

I can only put 10 unfortunately

[late summit]

Only one true answer

[brisk copper]

arp!

[undone sinew]

stealing my poll idea? you will be hearing from my lawyers.

[swift heart]

The best galaxies are the ones that drop bars

[stone zealot]

Where are my starburst galaxies? How xan i vote for my fav M82

[ivory mural]

m82 is a spiral isnt it

[swift heart]

Yup in the near infrared

[stone zealot]

Its classified as a starburst

[undone sinew]

nah bro dont leave out lenticular galaxies

[hybrid echo]

is he really gonna leave out interacting galaxies tho

[brisk copper]

where ring galaxies?

[cedar dome]

Most are classified as spiral galaxies

[cedar dome]

Gimmie a sec I’ll make another

I made this sleepily at like 3am and forgot most classifications

[brisk copper]

idc

[brisk copper]

where seyfert glaxies too?

or even quasars or blazars

[cedar dome]

There are very many galaxy classifications, I’m just trying to hit the major ones

[brisk copper]

those are major

irregulars are my favourite tho

[cedar dome]

I’ll include them then for ya, Gimmie a second

I physically cannot add any more

Discord doesn’t let me

[cold moon]

Whatever Arp 147 and 148 classify as

[cedar dome]

I ran out of room for any more :(

[hybrid echo]

ah yeah you dont have ring galaxies here

[cedar dome]

Idea:

•React to this if you like ring galaxies 💍

[brisk copper]

[cedar dome]

There you go

[brisk copper]

Arp 147 is classified as an interacting galaxy pair consisting of a ring galaxy and an early-type galaxy

(etg is elipse and s0 galaxy i believe)

[cedar dome]

It looked like an elliptical, could be mistaken

[brisk copper]

its ring and elipse

its a peai

[cedar dome]

…

[brisk copper]

idk how tf you spell pare

pair

had to look back

[cedar dome]

A pea galaxy?

[brisk copper]

ig so

[stone zealot]

Bro forgot starburst

[cedar dome]

Discord doesn’t let me put any moreeeee

[undone sinew]

guys what’s your #1 favorite object

cant really make a poll about it so im just gonna do this message

What's the lore behind every astronomy server being gay now?

[past maple]

What is even the point?

[restive fiber]

There are millons of people that are tired of it

[rain void]

Well, pride month ofc, just kinda never reverted I assume?

[rain void]

Bruh how are you tired of it, it's just an icon

I guess people are gay all year round ¯_(ツ)_/¯

[late summit]

if a pride icon is getting you tired, you should probably go outside

[ivory mural]

the normal logo

[static sapphire]

They recently added a feature to Discord so you don’t have to see the icon

[undone sinew]

listen not to be homophobic or anything but the server icon is a bit on the nose in my opinion

like its a very good cause but we cant just leave it like that forever it gets old after a while

it was perfectly fine for pride month but extending it for over 2 extra months seems a bit unnecessary

its like if it was lets say a halloween themed server icon for october but then we just left it like that all the way into december

[static sapphire]

Are you really pulling a “I’m not racist, but”?

[late summit]

Because pride is totally the same type of celebration as Halloween

[cold moon]

I agree on the fact that at some point it just becomes mundane and loses the meaning, but I really don't care that much tbh. After all it's the logo of server on ds lol, not that deep

[static sapphire]

Yes, that’s why they fly the American flag only 1 month per year in front of the White House

[undone sinew]

Me neither i dont really care that much but like im speaking for the few people here that have a problem with it by just informing you guys on what their hard-to-explain points may be

or they’re just flat out homophobic

then its like

Their problem

so whatever

[undone sinew]

i mean my argument wasnt really about being homophobic (because i’m not) since you could basically replace the pride server icon with literally any other cause and i wouldve basically said the same things about it still

[violet dagger]

hello

[dense perch]

thank you everyone for voting

[undone sinew]

why did everyone just unanimously choose hello

[dense perch]

because it’s peak

[undone sinew]

⤵️◀️↪️◀️↪️🔼🔼↔️↪️

[stone zealot]

Double standards at it's peak, this server really got ruined

Like why just not have that icon for the "pride month" and then change it to normal, it has been 2 months since it ended😭

[zealous cloak]

Good lord

[static sapphire]

Here’s a bucket for those tears

[late summit]

Please go outside and touch grass

[tender hollow]

Ah yes, a rainbow has ruined astronomy

It's beautiful

[summer turret]

Bait.

[summer turret]

How many clear skies you got?

[zealous cloak]

I think no ones imaging andromeda rn so andromeda

[violet dagger]

genuine question

[cedar dome]

If I’m lucky two, but most likely just tonight honestly

[summer turret]

Go m31

[violet dagger]

why do you even want to keep this server icon so bad

[summer turret]

At least make it chromatic abberation

[zealous cloak]

People kept bitching about it so now its staying

[summer turret]

I find a BS excuse

[urban quiver]

the icon is dumb. But like, who actually cares

[zealous cloak]

I don't really care but damn these kids just won't shut up

[cold moon]

Great colours choice

[undone sinew]

What even is the third server

[tender hollow]

That's OA, AB, and R/AP

[restive fiber]

Sorry

[mint talon]

hello

[proud quarry]

Because people keep bitching about it. Pride exists because there is intolerance in the world. No bitching, no problem, no rainbow needed

So much bother has been raised about a server icon, a completely inconsequential thing, which means there is still a problem

[brisk copper]

i personally, stop liking women when pride month ends, idk about everyone else

[brisk copper]

where "Hai :3" option?

[brisk copper]

ahhhh, the gay its infected meee

[proud quarry]

Yeah as soon as July hits all the joy and colour is drained from my life

[brisk copper]

depressing 😭

[proud quarry]

I jest

[brisk copper]

wat that mean?

[proud quarry]

I was joking

[brisk copper]

!!!

joke is illegal

banned

don genaro said there should be less meowing in general, im sad now 😭

[proud quarry]

[brisk copper]

i personally believe more people would want more meowing in general so thats whats gonna happen

[proud quarry]

Crazy work 😭

[brisk copper]

i need to invite a bunch of catgirls into this server

[proud quarry]

Furry astro server when?

[brisk copper]

hmm

there is a place

with just me and 1 other people

[zealous cloak]

Oh hell na

[brisk copper]

skill issue lmao

[proud quarry]

You should thank me im keeping the meowing out of general and putting it in another server

Also that probably would go horribly, every community I join on the Internet turns out to be hell

[zealous cloak]

[brisk copper]

impossible

ill continue meowing in general

[brisk copper]

hey, not every furry is bad :<

[proud quarry]

I know

[summer turret]

astro femboy

[proud quarry]

Trust me I do

[brisk copper]

im not actually in many furry communities

[brisk copper]

who?

rory?

[proud quarry]

I was

But that's not a story for an astro server

[brisk copper]

i am in a lot of linux servers tho!

[proud quarry]

HEY

[proud quarry]

Ooh nice

Hobby servers are the best

[brisk copper]

you should totally join :>

[proud quarry]

Linux servers?

[brisk copper]

yea!

I totally won't force you to become a Linux user

[proud quarry]

I would have no idea what you would be talking about but sure

Id join why not

[brisk copper]

xD

[proud quarry]

What is a kernel? I thought you made popcorn with those

[brisk copper]

😭

i hope ur jokinggg

[proud quarry]

Eh I don't really know much about it

But i know the difference lmao

[ivory mural]

wesley

Go check his new name

[static sapphire]

kernels are so bougie, real enthusiasts use the Commodore KERNAL

https://en.wikipedia.org/wiki/KERNAL

and yes it's called that because one of the developers misspelled the name

[undone sinew]

are the prices the same

[static sapphire]

obviously if you don't have to move it, the bigger one

the 16" is almost twice as fast

[delicate lance]

essentially yeah

[delicate lance]

I will have to move them for different purposes but i have more than enough room to preassemble it ahead of time

meaning i can just roll it out to whereever and then do what i want

[cerulean elm]

It doesn't matter. 16" is 16"! Get a forklift or get your dinosaur vitamins😂

[proud quarry]

Id go on steroids for that

[undone sinew]

absolutely soulless poll

[tender hollow]

Man crashes out over a rainbow

[cedar dome]

Womp womp

Probably complain in r/ap

[tender hollow]

R/ap is rainbow too

[cedar dome]

Oh I meant to say won’t lol

[summer turret]

No one cares on r/ap bc the icon acc looks good there

[tender hollow]

we have it set up the same way they do
it's in the background

[summer turret]

Yes but you've got the overstimulated version with saturation cranked onto 100000%

[tender hollow]

That's not why people don't like it

[summer turret]

Just desaturate it then?

[tender hollow]

also what do you mean oversaturated

This is just the base flag

[summer turret]

Whys it so much more vibrant than r/ap

[tender hollow]

Because the R/AP one is transparent??

[summer turret]

Then make this transparent

[tender hollow]

That makes no sense, there's nothing in our background that we need to make it transparent for

On the other hand r/ap has an eclipse photo on the icon

[summer turret]

ok

[tender hollow]

But again, people aren't complaining because of any kind of design critique, they're complaining because it's "woke"

because it's pride

[late summit]

litmus test

[summer turret]

I just don't get why the pride logo really needs to be there as the server icon.
We know LGBTQ human rights are political but in that case, why isn't BLM or free Palestine there?

[late summit]

The pride flag does actually include BLM

[summer turret]

Clarifying this: I 100% support members of the LGTBQ

[summer turret]

It's odd that the flag takes up 50%of the icon yet in the actual server there's nothing actually relating to them

It's 100% an astronomy based server

[summer turret]

I hope you get what I mean @tender hollow

[static sapphire]

This

[static sapphire]

Well cookies are round not square

sorry, biscuits 🇬🇧

[summer turret]

This doesnt help your point.

[static sapphire]

https://tenor.com/view/pride-rainbow-gif-26074069

The biscuit is exactly the same size as in the previous icon ¯_(ツ)_/¯

No one ever said that it’s not big enough about that icon or that the background in previous item was too large.

[summer turret]

....what?

then why did you bring it up?

i never said anything about the shape - only you

[static sapphire]

¯_(ツ)_/¯

Also there’s plenty of LGBTQIA people here in the server

[summer turret]

never refered to a circle

[summer turret]

plenty?
So 50% of this server. In that case name them all.

This server has 24k people
I highly doubt 12k of those people are part of the LBGTQ+

[late summit]

Shiv, I appreciate you, but don't you think you're bringing up extremely silly points?

You're seeing a pride flag in times of high uncertainty for a number of political reasons for queer people's existence, and instead not caring that the flag is there, you're going out of your way to make silly points to try to get people to justify having the flag in the icon

Genuinely, does it bother you that the icon of the server is not the entirity of the AB logo?

[summer turret]

my main point is that we dont need to represent this community by the flag where less than 50% of people are associated with

[summer turret]

what bothers me more is that the icon represents them but in the server there isnt anything

there just needs to be more clarity

[late summit]

Okay, say the server icon changes for Christmas, it's still an astronomy only server where nothing is related to celebrating Christmas, does this mean they can't have a Christmas icon?

It's a discord server and they're choosing to have the pride flag to represent queer people, who again, their existence is politican because boomers feel like making laws that stop them from being themselves - do you actually care that a discord server is doing this?

What clarity do you need?

[ivory mural]

#1379949653990309978 message

[late summit]

Exactly

[static sapphire]

You can count yourself

What kind of demented demand is that even

[late summit]

I am going by his logic of the server isn't about X, which is true - but how far does that go

[summer turret]

This counters your point

[static sapphire]

How many people on the server are actually biscuits

COUNT THEM

[late summit]

No it doesn't, it counters your point of "This server isn't about X, why do we have X on the flag"

This server isn't about Christmas or Halloween, but if they switched to a logo to represent that, I don't reckon many people would care (though I'm sure some still would)

I understand you not finding sense or caring about the pride logo, but is it really a big deal at all

[delicate lance]

As long as this particular version changes on Halloween/Christmss I’m happy

It can even be a themed logo with pride flag integrated

Don’t see why not

[late summit]

Yeah, I think themed logos are cool

[ornate glen]

One off statement here. If the server was to have a Halloween themed logo, and it stayed until Christmas, people would definitely have an issue.

[late summit]

I agree and yeah very likely that's the case

The difference is that pride isn't just celebrated on pride month

[delicate lance]

The reason the pride flag is there is what puts me off

[late summit]

There's a pride month yeah, it's the biggest western celebration of pride, but there's still plenty of pride parades and celebrations during the rest of the year

[delicate lance]

Why does one have to SPECIFY that they support them?

[static sapphire]

We had our Christmas tree at home up until April lol

[delicate lance]

We just take them outside and plant them into the ground

[static sapphire]

Well this is ‘murca, so it’s a fake tree

[tender hollow]

I still have a santa hat in my profile picture

Don't see anyone complaining about that

[zealous cloak]

https://tenor.com/view/cat-meme-gif-13914504713592771065

[static sapphire]

Might as well just leave it there

[delicate lance]

We’re afraid of your mod abuse

[tender hollow]

Yeah it'll be Christmas in like 4 months anyway

[late summit]

You have real trees? That's kind of neat actually

[delicate lance]

Yes..?

How is this abnormal

[late summit]

Many people live in apartments where it's not exactly easy to carry a big tree alright lol

Just not common at all where I'm from

Plastic tree that looks decent and is somewhat big, goes into storage when not in use

[zealous cloak]

Many people have fake trees. I would say the majority

[late summit]

Though now I want to have a real tree when I move into my new place

[urban quiver]

you guys dont have real Christmas trees?

[proud quarry]

Because it can't be taken for granted in this day and age sadly. The purpose of pride is to be visible so people know they are accepted

[delicate lance]

Oh no we take schmol trees

[urban quiver]

Thats a sad tree tbh

[proud quarry]

Better than no tree

I kinda like it

[late summit]

Ooooh

Ours goes up to the ceiling lol

[delicate lance]

Ours too

[static sapphire]

Tree btw

[urban quiver]

I get a nice 8 foot douglas fir from a Chrismas tree farm

[delicate lance]

They’re natural trees literally just fresh out the forest

[late summit]

Didn't notice, the angle made it seem smaller at first

But I mean ours goes up there and is relatively thick

[proud quarry]

Neat, we get them sometimes too. Plenty of pines here

[late summit]

Only because it can be taken down easily, otherwise we'd have one like that too but fake

[delicate lance]

There’s not any thick small trees here weirdly

[late summit]

You don't, it's completely optional and not saying anything is very valid

Just that whoever decides what logo goes up (I think Ben?) chooses to visibly support pride

[static sapphire]

We have 14ft ceiling in living room. I was wondering if I should get one of these giant skeletons for Halloween for inside

[delicate lance]

No the point is, we live in a society where you have to visibly show to support to it, rather than it being normal to support and abnormal not to

[late summit]

No we don't

[delicate lance]

Thats basically how it is here

[late summit]

The only people I see celebrating pride are queer people for the most part, both irl and online

Nobody cares if you're not walking about with anything pride on you, literally nobody

[delicate lance]

Not showing it lacks a foundation for members of that group to feel welcomed, at least to what I know

[late summit]

Have you seen anyone here complain that X user isn't celebrating Pride

[ornate glen]

cant even see it and it blends in with the bg

[delicate lance]

I phrased that poorly

My point is that support has to be shown rather than assumed

[late summit]

But it is assumed that people either 1. don't really care or 2. are supportive, both very valid options

[delicate lance]

I’ve had worse experiences

[late summit]

Nobody will see you as anti lgbtq for not showing support unless you go to a pride event, go to the middle of everyone and act like you don't wanna be there

[delicate lance]

Majority of people I know don’t support it and find it weird that me and my friend group do

[urban quiver]

polls 6.0 when

[late summit]

Or if you say homophobic things, but that's a way different thing

[late summit]

To be fair most kids are weird like that, can't judge the norms based on how kids feel about things

[delicate lance]

It’s not that not showing support = against, but that showing support makes one feel welcomed or accepted, meaning it needs to be specified. I am not inside that group and I only know like 2 that are and this is all I know, so correct me if I’m wrong

Sorry if I’m speaking unclearly my 2am brain lobotomy is kicking in

[late summit]

I see, that is different to what you said earlier (at least from what I understood)
Showing support does make people feel welcomed of course, but I don't think that not showing support is seen as a negative, specially if you aren't queer yourself

[delicate lance]

Sorry if I phrased it weirdly but yeah I agree. What I generally mean is that they should, regardless of visual support, feel accepted and welcome - which many dont.

[late summit]

Yeah that is true, but not really anyone in specific's fault

Just a reflection on today's political world around the existence of queer people

[proud quarry]

Visability makes people feel better

Once things are more hidden its easier to get into a bubble of negativity

[cedar dome]

Can you believe it? Christmas, just four months away!

[plucky vigil]

FireHDn was found dead in his apartment, it was determined that he ended his own life by shooting himself in the back 3 times

[late summit]

For clarity I dm'd him to make sure I'm not attacking him with anything I say

[proud quarry]

Dear God... they put a rainbow on it... everything is ruined

[late summit]

We're good and I don't think he has a problem with anyone in the convo

Beyond those he makes clear he does

[proud quarry]

Who, fire?

[proud quarry]

Fell from a high place with no signs of foul play

[proud quarry]

Sorry im a bit lost

[late summit]

Oh oops I thought he said Shiv, not Fire

Since it was Shiv who started the proper discussion

[proud quarry]

Oh aight

Its kinda showing how much debate its caused though

[late summit]

True, but I don't think it became rude or aggressive

Those are good debates to have

[proud quarry]

Yeah, I understand there are people who aren't bigoted or anything but maybe aren't totally part of pride

People are allowed to speak their minds (as long as it isnt hats speach)

Frankly though, sad to see how many people have left because they can't handle being associated with queer people

[fallen obsidian]

I have an opinion on the server icon but I’m too lazy to type it out

[vagrant basin]

Phone sensor

[proud quarry]

Summarise it in 5 words

[fallen obsidian]

Pride universally standard, Astro server

Hard to explain in 5 words

[proud quarry]

Ok yeah fair enough

[rain void]

🏳️‍🌈 👍

[rain void]

Easy

[proud quarry]

Yipeeee

[young quail]

Goodbye polls 5.0, at least your going out the same as polls 4.0

[proud quarry]

Huh?

[delicate lance]

N-II

[desert obsidian]

6743 Å

[undone sinew]

what even are these obscure bandpasses used for

[delicate lance]

imaging

[undone sinew]

wouldnt other filters already cover them

[delicate lance]

what.

do you think "Oxygen III" is just a funny name for a filter which gathers better data

[undone sinew]

No

[delicate lance]

OIII gives you data of doubily ionized oxygen gas within the target

[undone sinew]

Its hard to explain

What im trying to say

[delicate lance]

H-Alpha is under H-II

So it gives you data of Single Ionized Hydrogen

that is why H-Beta and H-Alpha trace the same areas

[undone sinew]

do these rarer bandpasses actually give results that differ a lot from other bandpasses

[delicate lance]

Theyre both emmision lines of Single Ionized Hydrogen

[delicate lance]

Yes

well sometimes.

[undone sinew]

like with the nitrogen filter you said what objects would that work on

[delicate lance]

N-II for instance is basically as bright as H-Alpha but also insanely close so unless you use UNB filters, you will see N-II and Ha in the mix

[delicate lance]

N-II is Ha on crack

youll find it basically in any DSO

besides clusters

[undone sinew]

i also heard some other ones like carbon, iron and helium are those also similar or nah

[delicate lance]

carbon and iron are rare and dim so theyre often referred to as "forbidden lines"

He-II is very common in planetary nebulae

It traces the hottest and most excited areas

[hybrid echo]

there are lines for everything
heres some examples from ngc 7027

[undone sinew]

oh my god

[delicate lance]

Green is argon

the rest is SHO

[delicate lance]

see how that traces other areas than all other lines do?

OIII is Blue, SII is yellow and H-Alpha is Red here

[undone sinew]

do you have other image examples like this

[delicate lance]

Zamn

[delicate lance]

theres barely any

QHY only recently brought out an ArIII filter

all exotic lines are basically not available comercially so you will have to make a custom order.

[hybrid echo]

yeah i mean thats actually a decently bright line, 20% as bright as Hb

[undone sinew]

got ar confused with au for a second and though they made literal gold filters

[hybrid echo]

dont worry
you can image in gold too im pretty sure

[undone sinew]

so does like

Every element

Have a line

[delicate lance]

no

well in theory they could but no

[hybrid echo]

pretty much
the issue is, most of them are dim as hell

[delicate lance]

you have to consider

theres a lot of elements which arent even in space

[undone sinew]

quick question what do those numbers represent

[undone sinew]

oh yeah

[hybrid echo]

wavelength, ionization, brightness relative to hydrogen beta

[undone sinew]

like the artificial ones

[undone sinew]

so a value of 1 would be equal to h beta right

[hybrid echo]

a value of 100 would be
its percentage

[undone sinew]

oh

actually is imaging in hbeta possible

[hybrid echo]

yeah its pretty bright

[delicate lance]

Yes its commonly done

Mainly in OSC filters

[undone sinew]

also one last thing about filters

whats the difference between using SHO compared to just RGB filters

im not sure if theyre supposed to all be used together or seperately

like whats the difference i genuinely dont know

[hybrid echo]

sho filters image 3 specific wavelengths, rgb filters image 3 wide bands of wavelengths

[cerulean elm]

SHO filters allow only a narrow part of the visible spectrum to pass trough. For SII is 672nm, Hα is 656nm and OIII is 500nm
SHO filters create false color because you assign Deep red (SII) to Red, Hα - Less deep red to Green and OIII - Turquoise to the Blue channel.
RGB filters allow a broader part of the spectrum at the same time.
590nm - 700nm Red
490nm - 590nm Green
480nm - 590nm Blue.
RGB filters are the only filters that create an image that represents the real color of the object imaged.
RGB filters are very susceptible to light pollution and full moon while Narrowband filters are almost not affected at all.

[undone sinew]

thanks

What about luminance filters

Are they just the whole spectrum

[hybrid echo]

no

[cerulean elm]

Luminance does exactly what it's name is.
The Luminance describes the brightness for the color channels. A brighter luminance corresponds to brighter colors and lower luminance being darker shades.
The luminance allows you to have higher contrast between colors and more separation

[undone sinew]

so is luminance imaged seperately or do you stack it with all the other filters

[late summit]

You shoot every filter separately

[cerulean elm]

Every filter is imaged separately.
You can not stack filters in front of the camera because they would have the light transmission of a dust cap .

[delicate lance]

you technically can

[undone sinew]

ehh with enough aperture anything is possible

[delicate lance]

when pointing at the sun true

[late summit]

It's not about that, if you put 3 filters in front of each other like rgb you won't get any light except the wavelengths that those 3 have in common, which is none

[undone sinew]

no i didnt mean the rgb filters i meant the luminance filter

i didnt word it very well i mean luminance with one single filter each not all at once

[delicate lance]

luminance is just UV/IR cut

[late summit]

Oh I mean, same thing, you'll get the wavelengths the filters share but you're just passing it through more glass

[cerulean elm]

Let's break it down a bit, because I'm talking from a monochrome point of view.
In mono imaging, the Luminance filter is the most OP filter.
But on OSC, a luminance filter simply allows you to image in broadband.
Most astrophotography cameras have naked sensors, that means the sensor can see from IR into UV. And since you can't focus the UV and IR at the same time like you do with visible light, you block it with an UV/IR cut filter (Luminance filter)
Color cameras figure out the Luminance based on pixel values and some fancy math.

Here's an example how the Luminance layer impacts the colors.
I combined my first image of NGC-7000 with the latest. And I added the Hα layer as a Luminance to the old image.

are yall serious bro why are all my joke polls getting deleted

When other people also constantly make joke polls but nothing happens to them

[static sapphire]

polls get deleted if they’re off-topic. Joke-ish polls are allowed as long as there is some effort spent to at least somewhat be topical

I do wonder what would happen if you shot luminance and narrowband

I know people do RGB for better background and dark details

So this is a high effort poll in your opinion?
