Comets

[wild sequoia]

mmm, clouds

[little moon]

Today was so underwhelming lol

[stuck knot]

😭

[little moon]

Kinda sucked but I had to gamble and try to check it out

[wild sequoia]

I am NOT seeing it

what about s1? nuh uh

[stuck knot]

Luckily we have enough time till the end of month, right?

Has to be some good sky at some point

[wild sequoia]

dude i live in the uk

[stuck knot]

Oh

My condolences xD

[wild sequoia]

there's been times where I haven't seen the moon for over a months because of how cloudy it is

I've missed at least 100 things already just because of clouds

[stuck knot]

yeah, I feel like czechia isn't that good place for astronomy either

and astrobiscuit is in london and survives somehow!

😮

[compact bronze]

When are you planning

17th?

have to do a fkking mosaic

[little moon]

S1 for early november

[wild sequoia]

again, like hell i am seeing that

it's a sungrazer

that gets a weird angle

and is only bright for 2 days

[gritty forge]

I will not be able of seeing it probably

[little moon]

Edited a friend's image to show what I could see

And that is still better than my observation

🥲

[gritty forge]

It's too northern it's only like 7 degrees when the sun sets

And there's buildings covering the first 10 degrees of the horizon

[static sage]

when clear comes

looking to be around thursday

[compact bronze]

Oh same

I shot untracked yesterday

[little moon]

Antitail really underperformed honestly

But yeah comet overall is looking wonderful

[orchid inlet]

love this image

[steel widget]

That's possible? I thoughts the movement of the comet might screw with the stacking process as the frames are aligned by the stars I believe?

[compact bronze]

More involved preprocessing

You stack comet separately

[steel widget]

Could you send a link to a tutorial? :o

[little moon]

Not my image first of all

Width of the FOV is 23degs

Pretty sure that the tail is around 30 degs, probably a bit less but still

[lavish lark]

hot damn

[stuck knot]

Cooooooooool

How wideangle is that?

What I did last time with a comet was register all photos, remove stars from them, align them with the comet, subtract background, add stars back

it was a much fainter comet, so I had a lot of very noisy photos

[tall crane]

not the best photo, but glad i saw it anyway 😄

[compact bronze]

yall are getting fantastic images

this comet takes u back to neowise doesnt it

antitail so long

[tawny elm]

im surprised how this thread has 3000+messages

whilw hall of shame is 2.2k

[lavish lark]

i think im like 30% of that lol

[tawny elm]

lol the t-corona borealis thing is dead

wtf happened to that? it was meant to go noav

[lavish lark]

no idea

ive stolen some random guys thread

[worthy steppe]

How to capture this blackhole.thingy

Bro same situation why is that happening to us

Why is the comet not visible to me? Even in the brightest times and no clouds,bortle 7 and right direction

[lavish lark]

are there any streetlights or something?

[worthy steppe]

No

[lavish lark]

wack

[worthy steppe]

It should be at the top of that building

It was above the building

[lavish lark]

thats too early

[worthy steppe]

I stacked around 60 frames still couldn't see anything

[worthy steppe]

Ehh

[lavish lark]

and also are you sure thats the western horizon?

[worthy steppe]

When should I capture today

[worthy steppe]

Yes 100%

101%*

[lavish lark]

i started seeing it when the sun was -12 degrees below the horizon

[worthy steppe]

Let's do it again

[lavish lark]

also i doubt that that is a b7 lol

[worthy steppe]

I tried 8 times

[worthy steppe]

That's not b7?

[lavish lark]

can you send like a photo during normal darkness

[worthy steppe]

I'll send u today

[lavish lark]

*doesnt have to be recent

[worthy steppe]

Oh

Lemme check if i have any

[lavish lark]

just need a reference for what "darkness" looks like

[tawny elm]

at least b8

[lavish lark]

hard to tell because of jpeg compression but thats not b7

[worthy steppe]

It could be that

[lavish lark]

nah thats not a b7

[worthy steppe]

Because that bortle data is from around 2015-2017

[worthy steppe]

Lol

[lavish lark]

yeah if theres been any development in that time then it would increase it substantially

[worthy steppe]

A lot of development 💀🙏😭

[lavish lark]

ok yeah b8 minimum

[worthy steppe]

I don't want my city to be more developed

[lavish lark]

maybe b9

[worthy steppe]

Alrr

[worthy steppe]

Not 9 ig

Because u can see stars easily

[lavish lark]

how faint star can you get naked eye?

[worthy steppe]

A lot of stars

[worthy steppe]

Stars are bright

Not very faint

Not very bright

[lavish lark]

but yeah b8

[worthy steppe]

Yeee

I'll try again today

I'll not capture until I see it

[lavish lark]

i dunno use venus and arcturus as a reference

[worthy steppe]

Or maybe long exposures

[worthy steppe]

So what do u use

[lavish lark]

i just see it naked eye

i dunno

[worthy steppe]

Lucky

😭😭😭

[compact bronze]

Same

[formal cliff]

For how long do you guys think the antitrail will last?

[steel widget]

Did you do all that manually or is there some script?

Imma try shooting the comet tonight as the weather is clear for the first time in forever

[stuck knot]

I think I used some comet tracker in pixinsigh itself, not manually

but I am not sure now, it's been a while 😄

Our weather might be ok tonight as well!!!!

well

might

[worthy steppe]

Attempt 9th

[worthy steppe]

@lavish lark the video is for u

[neon viper]

tried it again

[worthy steppe]

Wooo

[worthy steppe]

Bortle level?

[orchid inlet]

busy city lol

[compact bronze]

@lavish lark

But it'll last an entire week for sure

Soho still shows the anti-tail obscuring the sun

[compact bronze]

Tail is defined

[lavish lark]

i doubt it

[compact bronze]

That's what it shows

[lavish lark]

i could see it happening

but i doubt it

[compact bronze]

I don't think it'll die out

Imma shoot one day ahead

And do Wednesday with my 533

Also my 801 subs on the comet got deleted cuz I raged

Star alignment was just not working

[formal cliff]

It's too cloudy for me anyways but Thanks

[lavish lark]

i mean think of how faint it is now

[compact bronze]

I got it in 1 sub buddy

1.6 second iso 1000

It's pretty bright

[lavish lark]

wuh

[compact bronze]

Ye

[lavish lark]

why is my transparency so bad

[compact bronze]

idk 💀

[lavish lark]

took 3m to get it

[compact bronze]

It's ur atmosphere

I didn't stack my data cuz I didn't have enough stars

https://media.discordapp.net/attachments/1017848440866222090/1047575789811544155/attachment.gif

[lavish lark]

L

[compact bronze]

Yea

That is

[lavish lark]

do you mean the thin spike antitail or the broader one?

[compact bronze]

Spike

Spike is still visible in Soho

[lavish lark]

yeah no thats not surviving a week lmao

[compact bronze]

shit

[lavish lark]

it was barely visible on the 12th

[compact bronze]

Now it is

[compact bronze]

Yea well the tail was changing directions so

Still there

[lavish lark]

gotten way fainter though

[compact bronze]

Hm

[lavish lark]

plus i dont think thats representative of the visible part of the comet

[compact bronze]

Gonna go monitor the comet today as well

I've been tracking it and measuring bros brightness

[lavish lark]

wheres a celestialsail or descending when you need one

[compact bronze]

It got brighter here for me then it was Monday and then dipped down back to normal but visually visible still

[lavish lark]

they're the smart ones

[compact bronze]

Ohh

Yea

[lavish lark]

actually lemme check the tail simulation

(it way overestimated how bright the antitail would be, so if its not there in a week its almost certainly long gone)

ok its prolly gone

[compact bronze]

By 23rd

But it'll be around this week

https://youtu.be/tfUYDk3yCmE?si=HaW_uiNAQ_s9BGmN

[lavish lark]

yea

[compact bronze]

Good

[lavish lark]

prolly another few days

[compact bronze]

Ya

Forward scattering losing it's effect soon

[worthy steppe]

Loll

[worthy steppe]

Guys please explain what the hell is that disk

[compact bronze]

Uh what disk

[worthy steppe]

.

[compact bronze]

That's the anti-tail

[worthy steppe]

What's that

[compact bronze]

Look at front of comet here

That line

[worthy steppe]

Yes

[versed jasper]

What is the current magnitude prediction for A3?

Oh its literally above isn't it

[compact bronze]

That's the line

[compact bronze]

2.5

[compact bronze]

Lmao

[stuck knot]

Day 3

What's the probability of the clouds clearing up? 😭

[lavish lark]

the sun blocker?

that blocks the sun

because the sun is pretty bright

[lavish lark]

yeah and its only going to get fainter compared to the main tail

[stuck knot]

Hell yes

[compact bronze]

Ya

[neon viper]

smth like high B6 - Low/Mid B7

idk Bortle level varies a lot for me

B9 to my eastern horizon, but zenith/slightly west of zenith with very favorable atmospheric conditions can go down to B5 (in terms of seeing; the surrounding light pollution still has a very major effect on images taken with a cam)

[steel widget]

Let's gooo i too got to see it c':

[static sage]

imagine the views if the moon wasnt blasting

[worthy steppe]

Oh that's a sun blocker..

Never knew those exists

[worthy steppe]

Same

[rancid wave]

A3 Tsuchinshan ATLAS

[stuck knot]

I can see the antitail, wow

it's very faint, but it's there

[lavish lark]

visually?

[stuck knot]

No, just in camera

[lavish lark]

ah

[stuck knot]

I didn't have binoculars, so saw the comet just as a faint fuzz 😄

[lavish lark]

ah lol

[stuck knot]

single overcooked photo, looking forward to the stack 😄

[lavish lark]

wtf why does my 3m stack have so little signal

like its on par with that

1984

*from yesterday

[stuck knot]

Depends on light pollution a lot probably

[lavish lark]

yeha

whats yours?

[stuck knot]

😮 What is that betweenthe comet and lens? 😄

[lavish lark]

millions of bees

billions even

mayhaps trillions

[stuck knot]

👀

[stuck knot]

2 seconds, f/2.0, ISO 640, 135 mm

It's highly processed

[lavish lark]

bortle?

also ¿????¿??)?

got that much signal in 2s???

is there something like horribly wrong with my dslr

[stuck knot]

I guess bortle 6

[lavish lark]

id guess the same

[stuck knot]

but facing away of most of prague

[lavish lark]

oh 135mm

ok nvm

[stuck knot]

😄

[lavish lark]

it took up a similar portion of the frame lol

[stuck knot]

it's the all famous samyang 135mm, on APS-C

[lavish lark]

also on aps c lol

[stuck knot]

this is what the photo looks like unprocessed

lol discord made some niiice gradients

[stuck knot]

now what was my work process with pixinsight... I don't remenber anything 😄

[tame minnow]

jone

taken with phone in b9

[neon viper]

stacking isn't turning out super well (should prob look for a tutorial lmfao) but ykw I'm happy with this (single 13s exposure; f/4.5 and iso 400)

[compact bronze]

It was visual yesterday

Sunday vs Monday

Same time

[wild wadi]

forgot to post my stuff here

[hoary basin]

i might try it tonight but its still stupidly low and cloudy

[jagged valley]

It won't get much higher

Maybe 1.5x higher at most

And it'll be dimmer

How long after sunset until it's visible?

[neon viper]

fr? I live fairly north (~30°N, not super far north but yk) and the comet's still well over the horizon for me

[hoary basin]

I'm-36 deg

North guys got rlly lucky after perihelion and before perihelion it was about the same height

[hoary basin]

About 45 mins

Just barely binocular visible Rn

Getting more contrast by the second

[jagged valley]

I missed the whole thing

Stupid clouds

I'm pissed

[hoary basin]

U didn't get it in early October ?

[jagged valley]

Yeah I got it then

I'm talkin bout tonight

I really want to capture the stupidly long tail

[hoary basin]

Doesn't look that good from the images I'm getting Rn

OK now the tail is starting to show

Should have used the dslr for early October aswell

[misty wagon]

What focal length is this?

[stuck knot]

APS-C 135 mm f/2.0

[misty wagon]

[stuck knot]

It was too narrow for the comet really, the tail was sooo long 😄

I have some 50mm f/2.8 data too

[misty wagon]

Yeah I will try shooting it this evening, but I am thinking of what focal length to use APS-C 50 might be too wide, right?

[stuck knot]

depends

if you want it nicely against some landscape, 50mm might be nice

if you want real detail and the antital (if it's still there), then something tighter

[misty wagon]

I have a 55-210 lens, I might stop around 75

The problem is, I need to leave the house around 7PM, so I won't see the restults until it's too late to change anything

[stuck knot]

To change what? You can adjust everything at the site, right? Focal length, focus, exposure time 😄

Well, I don't know how late 7 pm is for you

[misty wagon]

Nono that's not what I mean. I have to go to work at 7PM, shortly after sunset. So when I set up everything the comet won't be visible yet, and after I come back from work to see the results, it will already be way over the horizon

So there will be some big guessing

[hoary basin]

my best try

its still just way to low

[stuck knot]

ooo I see

That's a lot of guessing indeed, need to have that automated

in that case I would go more wideangle side to be safe 😄

75 sounds nice

[stuck knot]

Nice one! For me it was like 17° above horizon when it appeared yesterday

[hoary basin]

damn thats very high

[stuck knot]

I was surprised how high it was

[worthy steppe]

Will I be able to spot it today?

(tried 9 times,9 days)

It's day 10

And cloudy

[stuck knot]

😭

I failed only twice

and it felt like too much

[worthy steppe]

Ask me how does it feels

😭😭😭

[stuck knot]

I can imagine

Maybe today!

[worthy steppe]

Lesseeee

[worthy steppe]

Attempt 10th- failed

[orchid inlet]

sad

[compact bronze]

@lavish lark How long should each sub be for the comet if tracked

[compact bronze]

It is there still

Just faint ish

[stuck knot]

NICE

I am all ready for it 👌

Yeah, was very faint yesterday as well

[worthy steppe]

GUYSS

IVE ALREADY CAPTURED THAT

need someone to Process my stack pls pls pls

[wild sequoia]

antitail

[tame minnow]

try again lol

[worthy steppe]

uhm

bro it was impossible

[tame minnow]

how much integraation?

[worthy steppe]

😭

[worthy steppe]

4 sec exposures of 60-70 subs

[tame minnow]

y was it so dim then?????

[worthy steppe]

I DONT KNOW!!!

[proven token]

Not mine but from a friend

Check out the bow shock

[tame minnow]

thatss really weird

[worthy steppe]

ikr

it was invisible naked eyes

[tame minnow]

i saw it with naked eye in b9

it was super noticabble

[tame minnow]

bruh

[worthy steppe]

it was invisible from b8

😭

[tame minnow]

clouds?

[worthy steppe]

all clear

[worthy steppe]

this

is

awesome

[tame minnow]

https://tenor.com/view/what-wut-pepe-the-frog-shocked-surprised-gif-15389416553763135269

[tame minnow]

bro lives in b80 or smth

[worthy steppe]

🤣

[tame minnow]

same here

[worthy steppe]

dang

[tame minnow]

i took 40smth 11sec pics forr mine

[tame minnow]

.

[worthy steppe]

WOAH

[kind cliff]

Right over Rome

and discord destroyed my picture again

[lavish lark]

i went with 25s for 180mm and it wasn't trailed

[compact bronze]

Is longer then that gonna blow out the core

[lavish lark]

yea it was actually blown out lol

[compact bronze]

Dawg

💀

[lavish lark]

*just a few pixels

[static sage]

might as well plop it here

[kind cliff]

How is it that everyone got a better pic than mee 😭

respect tho

this is amazing pic

[little moon]

I didn't even get a pic so yeah don't complain too much lol

Stupid decaying hurricanes dropping storms over here

[kind cliff]

damn i feel bad for you

[little moon]

Eh

It is what it is

[kind cliff]

hope you get some clear skies early enough to see the comet

[little moon]

At least I got a privileged observation of neowise back in 2020

But yeah that 30° tail?

Not a chance

[kind cliff]

yea i got it small cuz the tail on the 13th had that size and that was the only day i could capture it since every other day its cloudy

[static sage]

its unreasonable how long the tail of this comet is, wild

[kind cliff]

niice

[lavish lark]

at least you can image all the lame post naked eye stuff

[static sage]

is the brightness gonna fall off fast now?

[lavish lark]

would prolly still have a long a** tail even then

[little moon]

Yeah, much larger than expected

[lavish lark]

yeah probably

like 4th mag by the 20th

[little moon]

Yeah

[static sage]

jeez

[little moon]

Idrc about images

[kind cliff]

sadge

[little moon]

I want to see it

[lavish lark]

forward scattering is dying

[kind cliff]

same

[static sage]

welp, should still be pretty cool on pics so im fine with it

[little moon]

I do take neat stuff not to bragg but

Yeah I want my own sensors to see it

[lavish lark]

in terms of naked eye?

[little moon]

I swear, NOTHING surpassed the feeling

[kind cliff]

yes

[little moon]

Back on July 18th 2020

[kind cliff]

i can relate

[lavish lark]

i think the peak for me was the 14th

[little moon]

I did not give a sh!t

The images came out of focus

[lavish lark]

*possibly due to circumstances

[little moon]

And noise was huge

But I did not care

Because the view

[lavish lark]

but that was a long ass tail visually

[little moon]

I got to see it from a bortle 2

Moonless

Seing that silvery thing just hanging

It very much surpasses any image

[kind cliff]

i tried getting some pics yesterday but that stupid saharian powder had to cover the sky ofc

[lavish lark]

society if a3 was in a new moon:

[static sage]

it is kind of a bummer that the moon is blasting but what can ya do

[little moon]

Yeah

[lavish lark]

like imagine if all of that was naked eye

[little moon]

And I can't say much about that drunk ass kreutz coming

I don't want to hype myself

[lavish lark]

*20 degrees

[little moon]

But god I hope it pulls something off

Bcs I am definitely missing A3 completely

[kind cliff]

same

unfortunately...

[little moon]

And even if I don't, even if tomorrow I get some clear gaps

It won't be that good I think

I highly doubt I see those 30 degrees people have seen these days

Perhaps by sunday 20 we could get some lovejoy-like stuff from dark skies

But that's about it

[kind cliff]

tomorrow if sky is clear ill go to the countryside to see A3

i hope..

[little moon]

Predictions don't support my plans but

I am watching the forecast like a hawk

[lavish lark]

the 20th in a b1 might be on par with like the 16th

might be

[little moon]

I doubt it will even be spectacular tomorrow anymore

But yeah

And yea 20th could be interesting

[kind cliff]

ik

[lavish lark]

*for like 20 minutes until the moon rises

[little moon]

But yeah I missed the whole show

[kind cliff]

ill try tho

[little moon]

14th and 15th

[kind cliff]

Im sorry for you man

[little moon]

Eh

[kind cliff]

i wish you can see it atleast tomorrow

[little moon]

Thanks

Probably won't surpass neowise for me

But yea

[kind cliff]

ik

[little moon]

July 18th was just ridiculous

17deg tail from b2

[kind cliff]

but it will be cool anyway

[little moon]

And it was a conspicuous brush of light

[lavish lark]

got like a 10 degree tail from b7 lol

[little moon]

If only my binocs weren't broken

[kind cliff]

mine didnt surpass even 4 degrees

on 13th

prob 5

degrees

[lavish lark]

yeah i got 1-2 degrees on the 12th lol

[kind cliff]

loll

[little moon]

Yeah 2nd to 14th was shitty

[lavish lark]

i think the 12th may have been the coolest day to image it

[little moon]

Evening days were insane naked-eye

[kind cliff]

WAIT

[lavish lark]

because of all the imageable detail

[kind cliff]

IMMA HAVE A GAP BETWEEN THE CLOUDS

NO WAYYY

[little moon]

Lucky

I have to make sure of the weather since I have to travel quite some distance to even image

[kind cliff]

well i live in b8

but i still saw it

naked eye

first comet in my life also

[little moon]

Lucky

[knotty crane]

Tail was huuuge

[kind cliff]

i wish...

[little moon]

It's like 7th for me (if I see it) but only 2nd naked eye

Actually

I did kinda see it on the 14th

Punniest star-like, almost undiscernible thing ever

[lavish lark]

simply become minnesota pilled next time

[little moon]

May have even been my imagination

[little moon]

Website?

[lavish lark]

zoom.earth

[little moon]

Kk

[lavish lark]

(thats the url)

[lavish lark]

*days 12th-18th

[little moon]

Oh okay

So far it seems that 17th and 20th may be okay

Unfortunately I missed the prime

But oh well

[lavish lark]

yeah the 17th is def like the last ok day

18th-19th suck

20th is only good in b1

[little moon]

Yeah b1 is not possible for me

Maybe b3-b4

Maximum

Hold on

[stuck knot]

Awesommme

[little moon]

Ok yeah I thought it suddenly got clear but nvm

[stuck knot]

So long!

Much clouds and more moon today 😦

[river patio]

It doesn't look hopeful

[lavish lark]

a3 is still in the soho fov

messed up

[worthy steppe]

WOOOAHHHHHH

[worthy steppe]

Ikr

[worthy steppe]

Can u show ur one

[kind cliff]

here

[worthy steppe]

Bro u got much much much much better than mine

Feeling shame to even post here

[lavish lark]

hey you did see it though

[little moon]

He didn't

Only imaged

Unfortunately

Good image though

[worthy steppe]

No..

[worthy steppe]

Yeee

[worthy steppe]

Tysmm dude

I'll take calibration frames and then stack and process

[lavish lark]

i count imaging as seeing

which isnt true

or how its meant to be usef

[worthy steppe]

Ah

[worthy steppe]

Yeahhh

[lavish lark]

(in my defense im not very smart)

[worthy steppe]

🙏🙏

[lavish lark]

its gonna be like a year before i stop processing this data is it

[steel widget]

My try at stacking the comet, def not the best edit, but im just happy i saw a comet :D

Bortle 6 over light dome x.x

[river patio]

Caught it. But the clouds were moving fast so I can't stack all the footage. Tomorrow will be my last try

[proud dew]

me and my firend, got 84 15sec iso 100 exposures of ATLAS but DSS cant register more than 2 stars, is there a way to align them by hand in other software?
(random frame for feferance)

[worthy steppe]

Wow

Should I capture it with my celestron powershitter 76Az

[topaz fulcrum]

i mean why not

[worthy steppe]

(it's very very hard without a tracking mount)

[topaz fulcrum]

comets really bright tho

what cam are you using

[worthy steppe]

Not for me

[worthy steppe]

Sony alpha 3000

[worthy steppe]

But I'll use my phone on that

[topaz fulcrum]

android?

[worthy steppe]

Ofc

[topaz fulcrum]

deepskycamera right

[worthy steppe]

No

[topaz fulcrum]

whar

why not

what are u using then

[worthy steppe]

Pro mode

[topaz fulcrum]

husk

yea dont use pro mode

use deepskycamera

[worthy steppe]

This is what I got from my cam

[worthy steppe]

I've used that

[topaz fulcrum]

in it you can set a delay between each image i think

so in that time you can move the scope to put the comet back where it should be

[topaz fulcrum]

why dont you use it anymore?

[worthy steppe]

Ik!

[worthy steppe]

Because,it takes a lot of time

And not user friendly

[lavish lark]

they revamped the ui

[worthy steppe]

OH?

[topaz fulcrum]

you only need to know where a few things are

[worthy steppe]

I'm gonna download it then

[topaz fulcrum]

if youre talking about the pause between every image thats unfixable i think

[lavish lark]

its like ok now

[worthy steppe]

I mean I have big fingers,it was hard for me to adjust

[worthy steppe]

WOWHHH

[topaz fulcrum]

its just sliders and buttons

[worthy steppe]

It was crappp

Before

[topaz fulcrum]

literally the same as pro mode

[worthy steppe]

Google the old version

[topaz fulcrum]

i used the old version

[worthy steppe]

💀💀🙏🙏

[worthy steppe]

Oh

That red slider

[topaz fulcrum]

there was nothing wrong with it

[worthy steppe]

Omg I can't I just cant

[worthy steppe]

😭😭🤌

[lavish lark]

what the protostar are you talking about

[worthy steppe]

😭🙏

[topaz fulcrum]

unless im remembering it very badly it was still just sliders and buttons

i had no issue using it

[worthy steppe]

Forgive me Grand

[topaz fulcrum]

it didnt look great but it was usable

[worthy steppe]

Not for me

I downloaded

It's 138421 times better now

[topaz fulcrum]

very specific

[worthy steppe]

Loll

[compact bronze]

Send ur final image

When ur done

[steel widget]

Try siril's guide on comets? That's what I used

[compact bronze]

registering the comet?

[lavish lark]

yeah it didnt do that

[compact bronze]

u sure bud?

[lavish lark]

sure thats real?

[compact bronze]

yes

[compact bronze]

its a stack lmao

[compact bronze]

wtf

u aint even got the antitail to proof 😭

[lavish lark]

*bad dbe on purpose

[compact bronze]

damn

[lavish lark]

also i have no idea why dss decided to crop that much

[compact bronze]

dang lol

well I got douvle antitail

the prediction was correct

[wild sequoia]

that is not a b8
I live b7, near a b8-9, and my sky is nowhere near as light as that

[wild sequoia]

grah same
random storms just flying over me

[wild sequoia]

holy double antitail

[compact bronze]

probably split

[bright minnow]

Strait up couldn’t find the comet

At all

Had to trouble trying to find it a few weeks ago

But now

Not even my camera could find it

Wayyy easier last month

[tame minnow]

una faccia una razza

[tame minnow]

damn im sure u would have gotten an incredible image

[bright minnow]

Just not even there

Where it should be

[tame minnow]

i got a good pic with antitail with my phone

[tame minnow]

its time for us in the northern hemisphere to have some fun lol

[tame minnow]

im really proud of it

[little moon]

Doble antitail?

[bright minnow]

how is that fair!

; (

[tame minnow]

the comet was best visible from the south anyway

[bright minnow]

yeah but it was flat and boring

bairly visable ion tail

and i couldnt even resolve that

[tame minnow]

i dint see an ion tail either

[bright minnow]

Of the comet

Like this was my best image

And it’s just

Meh

[worthy steppe]

So what's thatt

[proud dew]

I'll try

[proud dew]

To stack it, DSS has a comed mode that allows for stacking the comet and background separately but for that it needs to see some stars and I only get 2

[steel widget]

I had same issue of not enough stars being detected, luckily siril has settings where can u can test w to increases sensitivity

[stuck knot]

I guess with this comet it's pretty hard to deal with gradients, right?

Given how wideangle all photos are

[proud dew]

Sirlil stacked 37 images and that's what's after an auto streatch, something weent wrong at the core of the comet but there is the anti tail visible even

[wild sequoia]

b10

face it nikky
you live in the infamous yet truly rare bortle 10
where even seeing jupiter, Mars (opposition) and Venus becomes a challenge

[compact bronze]

DSS sucks

Use Siril

[compact bronze]

Starnet tried deleting my core

[little moon]

Oh my I may actually have a chance at the comet tonight

Sadly my chances of seeing it visually are over thanks to the moon

[proud dew]

i didn't use starnet there

[compact bronze]

Yeah ik

[worthy steppe]

Jupiter is very good

I mean can spot it

Easily

[wild sequoia]

ik but
still
bortle 10

[worthy steppe]

Sori

[proud dew]

i saw it yesteday, moon comes up a bit after the moment of the comet becoming visible, there is a window tho some optics makes it way better, i used binoculars, it was incredible

[little moon]

Fair

[little moon]

I do want to see it naked eye since my binocs are broken

Perhaps I could use one of my finderscopes lmao

[orchid inlet]

te comet is not the easiest to find, but when you do find it you just cant unsee it

[little moon]

Yea

Dw I've seen a comet naked eye before

And I am sure that A3 tonight will not surpass it lol

[orchid inlet]

yeah

it's a really bright comet

when I called my family to look at it they couldn't see it

[little moon]

Was*

Not anymore unfortunately

Pretty sure that neowise will still be my best so far

[orchid inlet]

then I showed them the exact location they were all shocked

[little moon]

But hey maybe the finderscope view is good lmao

[orchid inlet]

yeah

[little moon]

Does anyone know how fast A3 is moving rn?

In arcsec

[river patio]

Vas a intentarlo hoy? Está despejado en Madrid

[little moon]

En Madrid no

[river patio]

😔

[versed jasper]

Can confirm

[little moon]

He ido al sur de la zona de Toledo

Mirando a Extremadura

Por aquí pinta muy muy bien

[stuck knot]

This probably marks the end of my czech capture of this comet, now it'll only be cloudy

But it was fun!

Time to learn pixinsight again

[versed jasper]

I live just north of toledo but it's partially covered. Are you by any chance in the ASAAF whatsapp group

[river patio]

No way I have clouds only on the sunset side 😭

[little moon]

Nope

I'm south of yebenes

[river patio]

At what mag it's Atlas now?

[lavish lark]

3-3.5th id estimate

very difficult to see naked eye yesterday

[proud dew]

i manually stacked (added) 72 frames in gimp but without calibration frames it's garbage really

[river patio]

Yeah. At bortle 7 I could barely see it.

[lavish lark]

like 4th mag nucleus

[river patio]

Clouds gods are being benevolent to me today

[lavish lark]

had to use averted vision to even see the tail

[icy yarrow]

hablas ingles por favor

[river patio]

I'm gonna try some untracked 1250mm photos. Apart from wide 50mm ones.

[lavish lark]

faint as balls

[versed jasper]

he returned to speaking english below, dont panic :D

[versed jasper]

is stellarium not accurate? says its 1.27

[lavish lark]

tf kinda stellarium you have

[lavish lark]

thats not accurate lol

[versed jasper]

i mean A3

someone asked about atlas, i assume thats c2023 a3

[lavish lark]

ohhh

apologies

i didnt see the message you replied too

but yeah a3 is also innacurate

[versed jasper]

okay

[wild sequoia]

yes

[tall crane]

i see it with the big telescope 🙂

[river patio]

It got cloudy but I caught like 20 min of data. Thats a win for me. Also some spooky Moon photos

[proud dew]

I
AM
DONE
i don't belive it could get any better

[split hazel]

this shot was at 200mm fl

[stuck knot]

Oh yeah, that looks about my apsc 135mm

[stuck knot]

Nice up close shot!

[thick skiff]

so i captured this comet tsuchinshan atlas and i dont know how to properly edit the data and i failed after alot of tries
can anyone edit it for me?

https://drive.google.com/file/d/1Lnrj5gHrLN8fgqZ22Cq_8a_-0ZF3EArL/view?usp=drivesdk

[proud dew]

750mm at 1.6crop factor

[thick skiff]

heres the tif file

[stuck knot]

Niice

[little moon]

I got to see it as well

[lavish lark]

hell yeah

naked eye?

[little moon]

I could see it

[lavish lark]

hell yeah

[little moon]

It was quite faint but it was there

Honestly I'll take that

Could trace 4-5 degrees at some point

Moon really washed out the tail

But yea it was visible

[lavish lark]

i think the transparency sucked last night

nucleus was as bright as alcor approximately

[little moon]

Was brighter in the image

[lavish lark]

(alcor is 4th mag)

[little moon]

Yea

It was like that

[compact bronze]

last sudnfay I cud see all 20 degre of the tail

it was wild

[lavish lark]

think the show is over now pretty much

[little moon]

Yea definitely

[compact bronze]

comet: let me just outburst

[little moon]

Oh ok

[lavish lark]

small chance of it being cool again on the 20th-21st

(keyword being small)

[compact bronze]

whats happeninf then

[lavish lark]

no moon

[compact bronze]

ofc

[lavish lark]

*for like 20 minutes

*then it rises and its joever

[compact bronze]

https://cdn.discordapp.com/attachments/794651916646350859/1293726341425791110/nervoushello.gif

the double antitail is gone

ikts back to a single tail

[lavish lark]

extremely weird

still dont trust it was fully real

plausible

but never appearing again is sus

[compact bronze]

yep

[compact bronze]

it a single sub proved it

[lavish lark]

yeah im not sure what artificial explanations there are

so it prolly is just real

[compact bronze]

yea

[neon viper]

I never got to see it naked eye unfortunately, but tbh its the first comet I have ever imaged and I'm more than satisfied by that

[little moon]

Mb

Found some fellow spaniards, sorry

Single 10s exposure

[lavish lark]

yep thats a3

[little moon]

Tail was still around 20 degs photographically

Visually did not surpass 5

But yeah still neat

[lavish lark]

yeah id imagine that the long part of the tail only has like 3 days left to live

[little moon]

Yea

Sneak peak at my scope images

Will probably reuse some flat frames
I give the comet around mag 3

[compact bronze]

I was able to see it

pretty well

[formal cliff]

Still cloudy for me...

[little moon]

It was comfy to observe for like 40 mins until the moon rose more

[little moon]

Ouch

Good luck

[compact bronze]

ohh

[little moon]

Btw

May be a stupid question but despite my experience on AP I have a doubt abt something

[lavish lark]

ok

[little moon]

I overexposed some of the images yesterday with the comet

[lavish lark]

ok

[little moon]

Are these worthy of stacking anyway?

I can see the comet anyway

[lavish lark]

the coma might be a bit clipped but it should work

[little moon]

Okay

I'll play with yhe data for quite a bit anyway

So yea

Planning to do a composite with foreground and stuff

[lavish lark]

ol yeah running the jpeg through graxpert (this is bad dont do this)

[little moon]

Those were 30s at f2.8 so I wanna make the most of the night

[lavish lark]

doesnt seem toooo bad

[little moon]

Or siril's background extractor

[lavish lark]

i say its bad because of the jpeg compression inbetween

you can dbe a comet just fine

[little moon]

I mean

It does look like an oversharpened 8 bit image

Lol

But yeah hopefully I should do just fine

[lavish lark]

the overexposed has given you the dynamic range of an 1880s film camera

[little moon]

Lol

Well hey Great September Comet of 1882 recreation

[lavish lark]

lol

actually the coma might not even be clipped

nope nevermind

[compact bronze]

siril dbe please

im done for rn

[lavish lark]

it was using a jpeg i dont think it could be good any way

[compact bronze]

fair

[little moon]

HAHAHA wtf is this thing on

Another S1 outburst to mag 10

[lavish lark]

no way s1 is surviving to perihelion bruh

[little moon]

It's on smth that's for sure

But yea we'll see

[compact bronze]

damn 💀

this comet busting and bursting

and then die

[little moon]

I mean it sure is fun as hell to watch this thing being on whatever it's on

[lavish lark]

this thing is so much more fun than g3

[compact bronze]

thsi comet is only for southerners

sadly

[lavish lark]

g3's just gonna puff away at 0.4 au like a coward

s1 is a girlboss

plays by her own rules

[tame minnow]

did u process my comet

[tall crane]

❤️ comet processing 🫠

[misty wagon]

How do you process a comet that is just over the sunset? I am planning on shooting the A3 this evening, but I am worried that I won't be able to stretch it well, because of the hue from the sun

[tawny elm]

the sun is below the horizon

[river patio]

Wow

[little moon]

Processing my footage rn

[little moon]

Hehehehe

[neon viper]

idk how to process comets so I'm just leaving mine as is I'm happy enough with it

[topaz mauve]

what scope and camera have you used even integration time?

[compact bronze]

I didn't sadly

[compact bronze]

Woah

[tame minnow]

six sages did

this is some RUNNING noise

[little moon]

Yea I do have some as well

Needs careful processing

[tame minnow]

will callibration frames fix this?

[little moon]

Maybe, idk tbh

I heard that running noise needs dithering mostly

But maybe darks could do the job, idk

[tame minnow]

what did u do about it

[little moon]

It was mild so I could process it well

And GHS helped too

[tame minnow]

wut is that?

[little moon]

Generalized Hyperbolic Stretch

Some very advanced version of the curves tool basically

[tame minnow]

oh ok

[tame minnow]

heres a dif proccess

[little moon]

Cool

[tame minnow]

im kinda impressed my phone did that

[little moon]

Fair

[tall crane]

https://discord.com/channels/794642864218439681/1296793385733980180

[compact bronze]

Running noise

[tame minnow]

imaa take some darks to try tto fix that

[compact bronze]

Darks won't fix that

Dithering will

[tame minnow]

wesly has never ditthered he just takes callibration frames

[compact bronze]

Darks don't fix walking noise period

they remove thermal noise

They don't capture walking noise

Wesley probably has good pa or doesn't stretch as hard

That's cuz he has an astrocam and walking noise is much harder to appear

[mild olive]

how much time do I have to image it

[lavish lark]

i just go until it sets

[mild olive]

roughly how much time

[lavish lark]

like 45 minutes

[mild olive]

what

[lavish lark]

?

[mild olive]

i mean like how much time until it fades away

[lavish lark]

depends on how faint you will accept

like 6th-7th mag by november

like 10th-12th mag by december

[mild olive]

damn

[little moon]

24h ago at 400mm

[wild sequoia]

update: still haven't seen it yet 🙃

[little moon]

Oof

[misty wagon]

Why is everyone so hyped about A3 now? I’m on vacation now and will only be able to shoot it next weekend. Will it still be doable? According to Stellarium, yes. But idk how it will be in reality

Okay I looked it up - apparently rn is the only time it’s visible with a naked eye and binoculars, but for photography it should still be okay

[soft leaf]

we saw the comet with our naked eyes

[compact bronze]

why do I like ZTF more even if a3 was visible naked eye

[soft leaf]

i dont speak astronese, im just in the group 🤷

[tawny elm]

media hype. there hasnt been a lot regarding this one

[compact bronze]

well I didnt pay attention to the media

maybe because it was my first comet?

[tawny elm]

prolly

my first comet i hated

[compact bronze]

oh 😭

that was my favorite cuz bro was easy to shoot

up at teh fcking meridian

[gritty forge]

This can be an album cover

[daring arch]

Got this with my phone

[little moon]

Just finished this wonderful image
From October 17th

[formal cliff]

It might finally be happening!

[little moon]

Wtf is this LOL

In what kind of crack is this comet on, seriously

It's so damn amusing

I think we can officially nickname this guy as "The Crack Comet"

[neon viper]

The Cracket

[little moon]

Fr

It's on some serious stuff rn

Like it just went from mag 13 to mag 7.5 in like 4 days

With several outbursts

[hoary basin]

Its so much brighter tonight wtf

[little moon]

Yeah idk what this thing is doing

[formal cliff]

That's insane

[little moon]

Yeah even if it vanishes eventually this thing is so funny and amusing to see

What a show

[steel widget]

Odds it becomes naked eye visible?

[tawny elm]

It's a sungrazer

[steel widget]

So high chance..? 🙏

[wild sequoia]

ikeya seki part 2

[tawny elm]

YOU CAN SEE THIS IN THE DAY

[steel widget]

RN???

No not rn I'm dumb asf srry

[steel widget]

Ooooo that looks sickkkkk

Can't wait for it

Damn stellarium ain't showing promising apparent magnitude predictions :(

[wild sequoia]

which stellarium r u using

[steel widget]

Mobile

[wild sequoia]

yeah stellarium mobile isnt that good for that kinda stuff

[steel widget]

Ah

Would you recommend web version more? I don't trust desktop as the satellite tracking is wack (at least for me)

[wild sequoia]

idk really, desktop app seems to work better

but yeah stellarium mobile dont use it for comets
a3 peaked at -4.something
stellarium mobile saying it would peak at 1.4

[steel widget]

Alr, ty for the tip

[little moon]

Probably not

During the peak it will be too close to the sun

[gritty forge]

That's crazy

[little moon]

Honestly yea

[hoary basin]

Should be visible in Solar scopes if it gets above mag -8

i wont be able to try cuz its at 2am :/

[little moon]

I doubt it happens

Maybe -4

Or -5

But yea

[wild sequoia]

I might actually see it finally holy shi
