Untracked Astrophotography

[sterile violet]

need to sleep soon

[little prism]

thats more like it

[hybrid basin]

Yes the lense is relatively old and it has very much CA

Thats why I had to step down from f/1.8 to f/3.5

And then it's probably better to just use a 300mm lens at f/6.3

[sterile violet]

re framing

[grave rapids]

IMO no

There’s plenty of resolution just need more light

[hybrid basin]

But 300mm f/6.3 is still better than 50mm f/6.3

[compact dust]

I think i am gone say a finale goodbye to this channel, because i bought a celestron CGEM Mount

[dusty gull]

300mm means shorter subs and more reframing...

[dusty gull]

Good for you! Hope you'll like it

[hallow tapir]

by

[compact dust]

Thx

[mint merlin]

This

[sterile violet]

speaking of this im going to add 30m of data to my 1h untracked

[dusty gull]

Not necessarily

Definitely not worth the effort but' with short subs some people do numerous hours

[strange seal]

Pointlessly though. You are well in to diminishing returns then

[hybrid basin]

Looks good, but how do you get a clear sky? I guess your equipment isn't so old, because it shows your progress of the last three weeks, but shouldn't the sky be cloudy?

[sterile violet]

i dont know

sacrificed a child

[hybrid basin]

How many? I have to try this too (I hope everybody knows, that it is only a joke)

[sterile violet]

it is?

[hybrid basin]

If you mean cloudy: yes it is for at least the next week (and it already was before except some days), If you mean if it is a joke: of course its no joke. Who doesn't sacrifices some childs fore one AP session for a relatively bad result? (meant ironically of course)

[sterile violet]

i mean its a joke?

[gaunt meteor]

What did you use for that it’s amazing

[sterile violet]

canon 2000d + 50mm f/2.8

[hallow tapir]

im getting closer to reaching barnard

[little prism]

I really like this picture since orion is not blown out

[hallow tapir]

here is the orion with stars

[little prism]

nice

[calm hearth]

Orion Nebula - with an 8" dob

[crimson fractal]

lower exposure time and u will get better res

[calm hearth]

yeah this is with lower exposure time

and more frames

not sure which one is better though

[grave rapids]

the first one is processed better but the second is better data

[calm hearth]

Maybe if I collect more I can get a better result

I'm blown away by the 178mc

It's my first camera and all but it's been amazing so far

[sterile violet]

untracked, stock and bortle 7. 40m ish of exposure
this is just a quick edit lol

[hallow tapir]

noise s

noise x

[sterile violet]

yeah should ask someone to do it

[hallow tapir]

i have it

i can do it if you want?

cuz i noticed its a nice image but kinda is a little noisy

[sterile violet]

sure one sec

[hallow tapir]

send tif

[sterile violet]

https://drive.google.com/file/d/1UTeHUZaW8N6Xunzxwjaq9vIlNmXcgKNS/view?usp=share_link

[sterile violet]

@me when you're done

[hallow tapir]

https://drive.google.com/file/d/1gg7guDG0uS5h9aWH1d8Y_NQa5uXbeRRx/view?usp=sharing tell me if it improved it

[sterile violet]

thanks so much man

[sterile violet]

made it worse imo

[hallow tapir]

oof

[sterile violet]

could you noise X the starless?

that would help it

its the stars, but it did the job

[hallow tapir]

ok

idk why i think it sometimes does that

[sterile violet]

https://drive.google.com/file/d/1YXMOlA0_9PaBJBGL7wT-6RK30ct94cXe/view?usp=share_link

thanks so much

[hallow tapir]

wait

i think i might of improved the star one

https://drive.google.com/file/d/1jOBDOdUZUxDcoOOenc0J394voQILIcZk/view?usp=sharing @sterile violet is this any better? (sorry i just got noisex recently im not the most amazing with it)

i think the stars are better now

cuz i made the original settings to high

[sterile violet]

thanks

[hallow tapir]

better?

ill send the starless now

[sterile violet]

thanks

ill play around with them in the morning

[sterile violet]

Still uploading?

[hallow tapir]

https://drive.google.com/file/d/12zO8zuuSEEgW8s9LjEK1d_PT8ssZQ31A/view?usp=drivesdk

@sterile violet idk how much it changed but this is with it’

[sterile violet]

thanks so much

[calm hearth]

I'm completely new to this

is this a usable sub?

I have like 250 of them

[sterile violet]

Where are the stars?

[calm hearth]

there are a couple of them but they are very dim

[dry spade]

Yeah, don’t know if you’ll be able to register that sub.

[calm hearth]

I don't get how people manage to get decent results with such short exposures

[radiant kestrel]

Ring nebula?

You need to have clear stars in each sub

[calm hearth]

I do have a bunch

[radiant kestrel]

I doubt stacking software would register

I don't see any in that sub

[calm hearth]

not a full image

just a crop

[radiant kestrel]

Oh?

[calm hearth]

can't open a single one now

don't know what's going on

[radiant kestrel]

Can I see a full?

Oh

[tidal tide]

it might register some of the noise as stars at some point which would be an issue

[calm hearth]

yeah they are not very visible

[radiant kestrel]

Yeah that's not going to work lol

[calm hearth]

looks like I'll just need darker skies

can't take longer exposures than that

[dry spade]

What scope and camera?

[calm hearth]

8" Dob, ASI178MC

but I'm in bortle 7 so can't do much more than orion

[tidal tide]

you could still try but no results are guaranteed

[calm hearth]

Any suggestions? For me the hardest is finding the objects

[grave rapids]

Buy the book Turn Left At Orion, a lot of the targets in that book are possible to image with a dob

And you can use it for visual astronomy because that’s what it’s actually made for

[radiant kestrel]

Wait what is this a picture of?

[calm hearth]

Supposedly the ring nebula

[calm hearth]

Yeah

I mainly bought the camera for planets

And it does that quite well

[dry spade]

You need at least 4 bright stars in view to get registration. At 1200mm that might not be easy. You could ramp the gain up, maybe?

Otherwise you really need longer exposures, either by using an EQ platform or motorising your dob mount.

[calm hearth]

yeah I am considering the latter as a long term project

[dusk mantle]

I processed a 3 second AVI video on orion nebula. My telescope was off colllimaton by alot seeing conditons were OK-BAD VERY humid around 0.5-1.5 mph winds rarely no clouds exept that one little steak I found oppisate of where I was shooting only wiht a 15 second exposure and atmosphrere was avrage wobble.

[strange seal]

That’ll work. Use siril and manually select them. Or dss and brighten up the image in the raw settings and use 2% threshold

[calm hearth]

Tried the second option, only worked for one single frame. I'll try it with siril

I also saw someone use a planetary worklflow, with autostakkert and it seemed to work well for them

[dusty gull]

Unstacked, unprocessed and final
Untracked with my dob under almost full moon

[hallow tapir]

very nice

[calm hearth]

Holy shit

That's incredible

This was my unstacked one but I got nothing close

[hallow tapir]

nice

i like core shots like that

they are cool

[calm hearth]

How did you stack it?

[dusty gull]

Nice! Maybe a bit too much green

[calm hearth]

yeah for sure

I didn't use any darks or flats

just my first test of dsos

[dusty gull]

Oh who were you talking to?

[calm hearth]

you

your shot is great

my raw images were much brighter but my stacked image isn't half as good as yours

[strange seal]

You edited it yet? Stretched etc?

[calm hearth]

a little

I got this

but siril won't save anything other than a black image

[strange seal]

You using the histogram transformation?

Open that and click the gear with the line icon. Then apply

[dusty gull]

Oh ok, thanks

Stacked in Siril and processed in Siril and PS

You have great details in the core!

But you should try what LMC said

[tidal tide]

we should have an untracked version of the BAT

[dusty gull]

Gathered 45min on m81!

[dusty gull]

100 000 subs to stack

[tidal tide]

nah everyone stacks their own data and then sb downloads the stacked tifs and stacks those

[dusty gull]

Oh yeah sure

Why not lol

But everyone's data is going to be so different...

[tidal tide]

doesnt the normal BAT also have a wide range of lenses and scopes?

[tidal tide]

pleiades with only yesterdays data, still need to stack what i got today then combine

[sterile violet]

good bye everyone

it has been good

[midnight flower]

congrats on getting a SWSA

[sterile violet]

Thanks

Just waiting for the clouds to go

[midnight flower]

oh they wont

[sterile violet]

Yep

[midnight flower]

new gear = new clouds

[sterile violet]

No subs yet

Im gonna get at least 1 sub

[midnight flower]

one sub if its long might beat your untracked photos

[midnight flower]

thats how good tracked is

[sterile violet]

No, my untracked where 1h

My subs are 1m

It wont be better

But 30m tracked may be

[midnight flower]

a 5 minute SWSA sub will be almost the same quality

[sterile violet]

Maybe a bit linger

CLEAR PACH

Lets go

[midnight flower]

this is 300 seconds on a unmodded no filter dslr

[sterile violet]

Damn

First sub inbound

So wierd shooting at 1m subs

[midnight flower]

im telling you tracked is so insanely better than untracked, 5-10 minutes of exposures will beat out most untracked 1 hours

[sterile violet]

Ill see

At least stacking wont kill me

[midnight flower]

what object

u shooting

[sterile violet]

M45

First 1m sub looking good

No noise at all

[midnight flower]

1 minute is easy on a SWSA, even with eh PA

[sterile violet]

That's why im doing it

[midnight flower]

try 3 minutes next time

then keep testing until you see trails

[sterile violet]

Mmm

Okay

[midnight flower]

if you feel its too hard cut it back to like 2 minutes

[sterile violet]

Its clear tomorrow so ill get 2h on orion

[mint merlin]

why only 2?

[sterile violet]

Clouds

[mint merlin]

oof

i finally have a good first light tnt where i can setup & PA nice and early

then test my subs and shoot til like 10

hoping to get around 3-4 minute subs since im shooting at a wide angle

ok lemme move this to smw else

[hybrid basin]

My image from last night. 47min at 85mm f/1.8. That's a quick process (auto stretch), but I'll edit it, when I'm back at home... The data is available in "share-your-data".

I removed the stars because of the CA, but I want to add them later

[tidal tide]

thats some pretty nice data it seems like, damn

[tidal tide]

nearly an hour on pleiades, god i suck at processing

[hybrid basin]

Looks good, but in my half hour of the pleiades a week ago were more details visible, but probably yours isn't as much processed as mine.

[grave rapids]

False, there are wayyy more factors than exposure time and processing

Light pollution, lenses, camera, sub length, etc all make a huge difference

[hybrid basin]

Yes, but I was at f/3.5 and in >B5, so it wasn't so good. Maybe all those small factors together make the difference.

[tidal tide]

i was shooting straight into the light dome, 190mm, 1sec - 1.6sec subs, F4.5

thats 2 stops less light

and my lens has some insane aberrations

[hybrid basin]

Ok that should make a huge difference

[dapper mirage]

Oh! Hi, didnt realize there's a thread for untracked 🙂

That's mine attempt at Pleiades, roughly 800 x 1" at 140mm (Fuji crop sensor)

And my Andromeda from last year

https://cdn.discordapp.com/attachments/418426047197872128/1054714246577000468/Andromeda_SIRIL_PS.jpg

[hallow tapir]

Thats pretty good for untracked

[calm hearth]

I tried this from bortle 4 skies

I think I'm still doing something wrong

just not very sharp

[hybrid basin]

Do you use bahtinov mask?

[calm hearth]

this was with my 178mc but just using a lens, not a scope

[hybrid basin]

You can use it also for lens (if you have one for your lens)

[calm hearth]

oh

I don't have one but at some point I'll try one

thank you

I'll probably buy one for the scope first, since it is what I use the most

also, on an unrelated note, is it worth buying a focal reducer for my 8" dob? My camera has a pretty small FOV

[hybrid basin]

But I don't know how often you use your lens for AP, because if you use it very seldom, then I wouldn't buy/print one

[calm hearth]

yeah I hardly use it

[hybrid basin]

I dont know. I could ask in "ask a nerd"

[calm hearth]

it's ok

thanks anyway

I don't think I'll be doing much AP unless I go ahead and build a goto mount and an eq platform for my dob

[hybrid basin]

The "problem" with dobs...

[calm hearth]

yeah

the main problem for me is finding any targets

they're impossible to see unless you take long exposures

especially from my bortle 7 backyard

I tried going to a bortle 4 zone but I still couldn't see anything other than the orion nebula and ring nebula

[hybrid basin]

Star hopping could be good for finding the nebula or star...

[calm hearth]

Yeah I'm pretty bad at it lol

But I found the ring nebula with it

[crimson fractal]

Planet will be pretty decent

[calm hearth]

yeah it's already pretty good

and I have a 2x barlow on the way so it'll be even better

[gaunt meteor]

My first picture with a dslr. The Pleiades star cluster 30x10/300 second exposure untracked, and the andromeda galaxy 72x10/720 second exposures untracked, first light of my new canon eos 4000d. The pledides one is a tiff file so you need to click it btw

[hybrid basin]

You are taking to long exposures, so the stars are trailing. You can calculate the maximal exposure time with a website like this: http://web.archive.org/web/20200121080401/http://www.sahavre.fr/tutoriels/astrophoto/34-regle-npf-temps-de-pose-pour-eviter-le-file-d-etoiles. Probably nobody can open your image of the pleiades, because its a jpg and not a TIF, like the ending says. In your image of the pleiades is some of the nebula visible, but only, when you overstretch it, so you need more exposure time. Also Andromeda becomes better visible, when you collect more data. For the focus: I don't know, if it is perfect in focus, but maybe someone else can evaluate it, because I'm relatively new too, so I don't have a eye for that, but beginners typically miss the focus especially in their first images.

[hybrid basin]

For the processing: I don't know what you use, and how much details 200 could get out of your images, but Siril is a really simple, free and good program for the beginning.

[midnight flower]

ty for all the help, today I am officially tracked

[tidal tide]

nice, good luck

[tidal wave]

I’m here now

Only 8 and a half minutes made up of 2 second exposures

Have a intervalometer on the way so I don’t have to press the shutter every ten exposures

8 minutes at 135mm compared to 26 at 55mm

[sterile carbon]

my photo of orion untracked got 18 minutes of exposure time i wanted to try to see if i could get the horse head but i didn’t and i don’t have an intervalometer and it gets kinda boring clicking away

[gaunt meteor]

Thanks for the tips, I used dss and gimp I’ll try siril today because it’s gonna be clear

[hybrid basin]

No problem. I tried to process it in Gimp first too, but Siril should be better for the beginning.

[gaunt meteor]

I also found out how to use my phone as a wireless intervalometer so it will be easier to take more exposures I’ll show you the results if it stays clear today

[tidal wave]

Very boring

Also I loose count easily

I have siril but never used it I should probably give it a try

[tidal wave]

reprocess with siril+gimp

[tidal wave]

got way more out of my data at 55mm

[tidal tide]

it looks a bit too blue

[tidal tide]

mind sending me the data? wanna give it a try rq

[tidal wave]

Here I’ll send the stacked tif file in a sec

It’s sending might take a minute

173mb and my wifi sucks

[tidal wave]

i just realized i'm sending the wrong one

[tidal tide]

[tidal wave]

It’s almost done so I’m going to send it anyway

[tidal tide]

what's the data you're sending for rn?

[tidal wave]

This one

[tidal tide]

ah ok

car 💀

[tidal wave]

Yee it has mind of its own

alright now to wait another half hour for the correct one to send

@tidal tide it finally sent

[tidal tide]

nice, i'll get to processing then

[tidal tide]

forgot to ask before but what is the pixel size and focal lengths of the images?

[tidal wave]

Focal length was 135

I’ll have to double check the pixel size

4.30

[tidal tide]

alright ty

[tidal tide]

first one, havent run through photoshop yet, gonna do the 2nd one as well and then photoshop time

[tidal wave]

looks pretty solid so far

[tidal tide]

2nd, photoshop time

[tidal tide]

nope, not anymore, the conversion to .tif for photoshop completely destroyed it, im gonna try 1 more thing

[tidal wave]

Dang the Orion Nebula still looks pretty good on the top one

[tidal tide]

yeah i dont think i can do better rn, if you get more data the better it'll get though

[tidal wave]

I’ll get some more starting the 10th, I’ll have my intervalometer and the moon should be less of a problem by then

[tidal wave]

alright I did another reprocess this time using StarNet to process the nebula separately from the background

Seems a bit green let me correct that

[tidal tide]

i did starnet as well inside siril but it was quite rushed

[tidal wave]

that's a bit better

I'll stop there until I get more data

i lied i went back to get some more brightness out of the nebula

[tidal tide]

seems better than mine, the core colours are still gone though, wonder how to bring that out

[grave rapids]

Forgot to post my best untracked image here

[tidal tide]

what fl? pretty damn nice

[grave rapids]

135mm

[tidal tide]

hmmm

i wonder if we could combine our data

[grave rapids]

Worth trying

[tidal tide]

send over stacked file?

[grave rapids]

ill ping you in my post in #1021002743080558642

[tidal tide]

alright

[grave rapids]

would you mind sending yours too so i can try

[tidal tide]

ill put it here but i have to dig it up first, brb

[grave rapids]

yeah np

[tidal tide]

cant put it straight to here, bruh

[grave rapids]

rip did you ever upload it

[tidal tide]

pretty sure i had mine in #1021002743080558642 too though

[grave rapids]

ok ill search for it

[tidal tide]

does anyone else here have data on the orion nebula and horsehead at near 100-135mm?

[tidal wave]

I’m getting ps finally

Been using gimp since 2018

Not for Astro though

[radiant kestrel]

Get pix if ur just doing astro stuff lmao

[tidal wave]

Nah I’m not

I do photography and graphics too

[radiant kestrel]

Understood, makes sense then

[inner crystal]

My best 2022 untracked

iPhone13 + monocular 8x42 (AstroShader settings: x150 1s, ISO 2500)
No where near as impressive as some of these others, but is captured, stacked and edited all from a phone... 🥴

[dusty gull]

I just discovered ngc 2146 and I think all the untracked fellows at high fl are gonna love it

It's quite dim (13mag/amin^2, so around the same as bode) but it is right next to polaris

At 650mm, I can do 9 second subs, untracked

Oh no-

I'm stupid

1.2 sec

But ngc 2276 is interesting too

Better magnitude and 4 sec subs

[gentle cipher]

@dusty gull thank you!!!

I was looking for a target

I'll try it

[tidal wave]

This should be helpful

[strange seal]

Some untracked pics

[grave rapids]

man i was going to post my orion image but whats the point when that one is above it

[strange seal]

Don’t worry fam I got u

[grave rapids]

much better

24 minutes on canon 400d untracked (obviously why would i post it here if it was tracked)

[tidal tide]

wtf happened

[strange seal]

F1.8 kit lens wide open

[tidal tide]

mhm, what do you even classify those star shapes as 💀

[strange seal]

Better edit on above data lmao. Fixed my monitor colour balance.

Gonna be clear tonight

[tidal tide]

one of my monitors is completely different too

[tidal tide]

lucky you

[radiant kestrel]

@strange seal might try a trapesium at some point. I saw it visually and I felt like the stars were very nicely defined (2k fl) any tips?

[sterile violet]

one of my monitors has like 0 contrast and the other one has a bit of ghosting

but that's to be expected bc they are some old vga led monitors

[strange seal]

More piccs

[crimson fractal]

hax

[strange seal]

4 1/2 mins of bin2

[hallow tapir]

nice

anyone made a mosaic with that deep fl?

like a orjon mosaic?

[dusty gull]

I tried once but untracked mosaics are a real pain

[short galleon]

I got this photo untracked with just a Sony mirorless camera and a 50mm f1.8 lens

Approx 32 minutes of data

And about 25 gigs

[strange seal]

Carina basic edit. Gonna get more data the fwhm on this data sucks

Might get a ROI on mystic mountains.

Although bin1 on the entire nebula would be hot.

[short galleon]

Oh wow nice

[tidal wave]

Got a little over half and hour till moon rise going for some more Orion data

[tidal wave]

Quick question can I stack a stacked image from a previous night with my current data or do I just add each frame from then to my current data when I stack?

Looks like I’m going to get around 16.6 minutes of data before moon rise

Which will add up to 25 minutes of total data adding my old data

There she is

Going for another 200 exposures will get me to a total of half an hour of combined exposures

[strange seal]

8 mins meathook

[tidal wave]

I got robbed of light frames

Took 700 but only 250 are showing up

That’s frustrating that’s 15 minutes of data lost

[tidal wave]

Hoping it was a problem creating a new storage file on my card because my current one just maxed out on 9999

If that was the problem I should be good for awhile

[hallow tapir]

only 8 minutes and untracked? Are galaxys not hard to get illuminated well?

i thought that would be way longer tbh

[strange seal]

galaxies are bright

[grave rapids]

a lot of people don’t realize that with a dark sky galaxies like this can be seen through the eyepiece

[tidal wave]

quick process of my data from last night

only 12 minutes of 3 second exposers because i lost most of my data

My weather forecast for the rest of the week is depression so I can’t make up the lost time

Gonna do a stack with some precious data sometime this week

[tidal wave]

final edit for now

Starless

Might do a more aggressive process of just Orion and running man later

[dusty gull]

I've just started imaging ngc 2146,looking good so far!

I aim to gather 3 hours on it

[dusty gull]

1 hour for now

[dusty gull]

Super quick process, I'll spend more time on it tomorrow!

At the end I got a little bit over an hour (clouds and dew joined together )

[gentle cipher]

what?!?!!?1
\

is that untracked

[dusty gull]

Yes

[gentle cipher]

how

its so good

[dusty gull]

It's the galaxy I talked about earlier, the one very close to Polaris

So I was able to take 1 sec subs

I have to admit Im kinda surprised by this result!

I was excepting way less

Surface mag of 13,3 is not good lol

[strange seal]

Oi @dusty gull do you ever get walking noise in your pics?

[dusty gull]

Yes but stacking on a long enough period cancels it out (as it's on different directions)

[strange seal]

Ah good good

[dusty gull]

Or I can turn the camera around while imaging

[strange seal]

I get it quite strong

I guess an aggressive rejection and the natural alt az rotation would help

[dusty gull]

Yes with rather short stacks it's a pretty strong problem

[strange seal]

My pc is sweating at the thought of processing 60,000+ subs lmao

[dusty gull]

I don't know about the pixel rejection tbh
You'll need a lot of frames and strong pixel rejection can kinda destroy the target (by experience, sigma value under 3 is really not good for my rig, reeeally not )

[strange seal]

I’ve been using median for most of my shorter stacks

Average image. 8 mins int. You edited this I think.

[gentle cipher]

Thats dusty hand isnt it?

Wow I didnt know you were talking about dusty hand galaxy

[dusty gull]

Another joy of untracked ap

But you could also try longer binned frames for the background only maybe

Then apply it with masks

[strange seal]

Yeah o normally bin2 or bin3 for big stuff

I got 15 mins on carina last night. Bin 1. Been processing since midnight and it’s 10am now. 160GB .ser file lmao

[dusty gull]

Tbh I usually have walking noise waaay stronger than that (at least on targets with longer subs, I don't know why but it looks like walking noise is stronger above 300/400ms)
AstroDenoise dose a pretty good job at hiding it too

Wow 160 gb

[strange seal]

Got it. So pump out a heapppp of integration time. Sorry pc

[dusty gull]

Good luck

[strange seal]

8.3 megapixel camera struggles

[dusty gull]

Yes I wanted to buy the uranus c while it what on sales but I thought that the 8 megapixels will be quite a big problem as long as I'm untracked

[strange seal]

I can bin easily

Bin 2 is 75% of the file size

[dusty gull]

Yes I forgot about that aspect but at 650 mm binning is kind of a big loss for most of objects

And another idea that popped up later is using roi

Manually adjusting it as the target moves

For targets with enough stars that don't fill the entire screen it may be interesting

Now I'm gonna sleep because I awoke in the middle of the night, it's 3 am here

[grave rapids]

Hey I don’t mean to interrupt but what target should I shoot next? 8” dob and 224mc

[strange seal]

ghost of jupiter

spirograph

crab nebula

[grave rapids]

Ok thanks

[dusty gull]

Planetary nebulas as he said

Also if bode or cigar enters the frame

But it depends on your hemisphere

(yes I can't find sleep)

[dusty gull]

See the walking noise

Autostretch on my stacked data @strange seal

And yet a lot of it has been reduced by rotation

[strange seal]

how much int was that?

[dusty gull]

1 hour

[strange seal]

noice

my longest int so far is carina. i got 15 mins. im limited by storage space though lol

Some targets I have in mind

[dusty gull]

Wow that framing

[crimson fractal]

dew it

[strange seal]

I will.

[crimson fractal]

waiting for the moon to fuk off ?

[strange seal]

Bin 2 and maybe 30+ mins of data. Not sure if I have the patience for 1 hour

[strange seal]

It’s pretty good now. I can get a good couple of hours before it rises

[dusty gull]

What is the surface mag of these?

[crimson fractal]

i packed up last night purely cuz the moon was coming up

[strange seal]

13-14 tops I think.

[dusty gull]

Nice

[strange seal]

@dusty gull what calibration frames do you take?

[dusty gull]

Only darks

[strange seal]

i take bias, still experimenting with integrating them

[dusty gull]

Afaik bias are contained in the darks

So they're not really useful unless you use flats or dark optimisation

[tidal tide]

Man, thats good. I would try this target but at 300mm it would be tiny

[dusty gull]

Ty, what is your camera?

[tidal tide]

DSLR, pentax k3

With the crop factor its a bit more but still

[dusty gull]

You'll get about the same sampling as I had when taking my bin 2 data

[tidal tide]

What f ratio were you on though?

[dusty gull]

Qui process gave this

F5

[tidal tide]

Would be like F5.8 for me

[tidal tide]

goddamn

[dusty gull]

It may be worth trying then!

If you dont have smth better to do

[tidal tide]

Pretty busy waiting for clear nights

[dusty gull]

Yes same

I got lucky last night but winter is hard

With your rig you can take 3 sec subs on this galaxy @tidal tide

Pretty good

(I was at 1.5)

[tidal tide]

Thats pretty nice yeah, would it even show up in single subs though?

[dusty gull]

Yes live view was relatively good

[tidal tide]

hmm, when i was doing bodes and cigar they showed up decently well

[dusty gull]

It looked better because i can stretch live view with sharcap...

[dusty gull]

They're about the same

[tidal tide]

thats actually pretty good

[dusty gull]

It's a little less bright but not that much

[tidal tide]

guess ill put this target on my list for the next clear night then, i want to try and get dumbbell too though

[dusty gull]

I'm searching for all interesting objects

Ngc 772 is very cute but surface mag of 14 is a bit too dim I think

Weird, stellarium seems way off on surface mag of objects

The ic 1727/ngc 672 duo would be fun

Also pretty dim

I think I'm going to do something stupid

[dusty gull]

@strange seal if IC 2431 is visible where you are, you have to try it

3 merging galaxies at surface mag of 11.8

[strange seal]

little far north

also its flippin tiny

[dusty gull]

Yeah but its so cool

You could definitively see the blue ring

Would be 80 pixel wide

Not that bad

Wait

I'm stupid

Mixed up ic 298a and ic 2431

[tidal tide]

that is crazy small though

[dusty gull]

@strange seal There's a banding suppression function in sharcap

Sharcap pro only though

[strange seal]

[dusty gull]

Oh its not that expensive

15€/year

[gaunt meteor]

My first Orion Nebula 300 5 second exposures, 25 minutes integration time untracked I used the canon eos 4000d with the kit lens 55 focal length

[burnt bay]

Nice work

Nice Flame Nebula

[short galleon]

I took this witha mirorless camera at 200mm with a total exposure of 32mins

Sony a6000

[tidal wave]

first attempt at the Pleiades

30 minutes made up of 1050 2 second exposures

[upper pasture]

Not sure If I've posted this in this server before, But my first time trying Orion, 20 minutes of exposures processed by someone in another server. I did a little edit

I might have been slightly out of focus

[strange seal]

Carina

20 mins int

[dusty gull]

Niice
The stars look a bit saturated however?

Maybe personal taste

[strange seal]

Yeh RGB alignment artefacts

I tried fixing them but it didn’t work and left black rings.

[dusty gull]

I'm sorry i'm tired af
I meant too bright

I cant find my words

I need to sleep

[strange seal]

[dusty gull]

The problem is that I cant

Like half of the time I cant find sleep (the other day I went to bed at 10 pm and managed to sleep at 3 am)

The other half I awake super soon and cant sleep back

ANyway

Anything to say before I call it final?

(if I wasnt clear, anything to change before I stop editing it)

[tidal tide]

blurx

[dusty gull]

Yeah, like if i didnt had a tracking mount but had the money to buy pix and blurx

[tidal tide]

i remember there being a tool that can be used for deconvolution though and which is free, dont remember the name though

[strange seal]

photoshop has a sharpen tool which is quite (very) good.
siril has decon and wavelets (very good)

@dusty gull

[dusty gull]

Yes thanks, I already used them

The data was too noisy to give good results

[strange seal]

quick sharpen

[dusty gull]

Oh ty! what did you used exactly ?

[strange seal]

quick brighten + HLVG plugin + smart sharpen

[dusty gull]

Ok i'll try that

[strange seal]

these settings

any more and stars went weird. you can mask them out if you werent as lazy as me

[little prism]

What should I shoot? I'm untracked with a bridge camera (f/2.8-f/9 and 25-300mm)

[upper pasture]

Widefield Orion?

[little prism]

I could do that

[dusty gull]

What do I shoot tonight, m31, m81, m82 or m51?

[tidal tide]

comet

[dusty gull]

Isn't visible yet

And there will be clouds when it'll rise

[little prism]

comet will be visible after like mid January for me

[tidal tide]

i could see it already if there werent clouds, and if i had a telescope or binos

[grave rapids]

M81

[tidal wave]

Reprocess

[dusty gull]

4 galaxies, 1 pn, 1 star cluster

Productive night

[dusty gull]

I decided to do about 30 min on many targets, m81 included

[grave rapids]

Ah nice

[dusty gull]

Not talking to much bcs my fingers are frozen

I did m81 82, needle, surfboard, clown nebula and m34

Will do the same thing for the most interesting targets and stack several nights

[dusty gull]

Quick exposure with almost no process on ngc 2392 at 650mm fl

I'll process the rest tomorrow

[gleaming walrus]

Just take lot of subs 😅

Sorry for spamming

[strange seal]

They are very very nice for untracked

In general too

[gleaming walrus]

Thank you 🙂

[dusty gull]

Yep, very nice!

Alright I started processing

It looks very nice

I'm out of focus on needle though

(by nice I mean for untracked and short integration obviously)

[gleaming walrus]

Is this untracked? 🤯

[strange seal]

Yep

With 8” dobsonian and Uranus c

[upper pasture]

Nice Milky way Shots!! And Orion looks great.

[gleaming walrus]

Wow 🙏🏼😶

[gleaming walrus]

Thank you 🙂

[upper pasture]

That Orion looks awesome, the more i look the more i see. Didn't see Witchhead the first time i looked

And the dust around Orion's head

[gleaming walrus]

I haven't gone deepfield till now

[upper pasture]

The most I've gotten in my ap journey so far is Horsehead. I'm happy with it.

[gleaming walrus]

Yes, it was only 50 mins or less I think

[upper pasture]

fr? jesus

[gleaming walrus]

Forgot the exact exposure time

[upper pasture]

That looks like much more than 50 mins lol

[gleaming walrus]

Yup

[upper pasture]

I'm currently collecting M45 data, But after that I'm going to continue my Orion Data

[gleaming walrus]

Awesome

[tidal tide]

what bortle though? looks pretty wild

[gleaming walrus]

B4
And checked the exposure time, it is 44mins44secs 😅

671 × 4secs subs

[upper pasture]

that's a whole lotta dust for only 44 minutes lol

what fl?

[gleaming walrus]

50mm on a7iii

[upper pasture]

Nice, I might try something similar with my t3i actually

[gleaming walrus]

Aperture was F1.8

[tidal tide]

was thinking B2-B3 but that makes sense too, there's some weird gradients left there

[upper pasture]

Lp map says I'm b4 but I think I might be B3

[gleaming walrus]

Most images are with T6i except this and 1 milkyway core image

[upper pasture]

Your image has inspired me to collect more Orion data lol

[tidal tide]

hopefully when i go to B1 this weekend it'll be clear

[gleaming walrus]

Haha yeah, A friend helped me in removing the gradient

[upper pasture]

In my past Orion data, I got HH and a bit of the beginning of barnards loop

20 minutes of decent data, and 20 minutes of shitty moon washed out of focus data

[gleaming walrus]

This is how it looked 🥶

[tidal tide]

lemme find my previous b1 orion

[gleaming walrus]

Moon was near orion 🤣

[gleaming walrus]

Awesome, should have gone for some more mins

[tidal tide]

i should seriously organize my files oml

this was like a bit over 10m from b1

def need to get more though, i'll probably try the comet once im back there and maybe a bit of orion

[upper pasture]

damn that looks sick

[tidal tide]

wish i couldve put the whole night into it but clouds and it was near the peak of the orionids meteor shower at that time

[upper pasture]

still looks good

I can't wait to see how my M45 looks.

[upper pasture]

My M45 data is in #1021002743080558642

[tidal tide]

did solar for the first time today

[little prism]

my untracked orion. 1h 7min in bortle 5.
(more details are in #deep_space_pics )

[little prism]

b1 my dream

[strange seal]

little galaxy cluster. 19 mins of data.

[little prism]

nice!

[little prism]

I love the brown dust. i think you can see it pretty clearly

[burnt bay]

Great stuff

[dusty gull]

Wow.
My mom posted my compilation picture on a group and dozens of people commented that it was impossible to get these with my material and I was lying

They ended up banning her

[little prism]

those people had skill issues

[burnt bay]

[dusty gull]

One even stalked my mother lol

She searched some infos on my mom and found out she was a violinist, so she said "if you have the money to buy a violin, you should be able to buy better rig for him"

Ok

What?

[tidal tide]

bruh tf?

[dusty gull]

Yeah exactly

Tf

[grave rapids]

That’s because a large percent of the people in this hobby are dickheads

[gentle birch]

15 minutes of untracked orion in bortle 8

[crimson fractal]

Bruh wtf

[calm hearth]

honestly that is a stupid assumption

Being a musician is expensive. I am a violist myself and I would have been able to spend way more on an astrophotography setup if I wasn't. I love music though, and I couldn't ever see myself giving up on it. Sad to see that people don't have common sense anymore.

[crimson fractal]

I literally can’t complete with u anymore

[calm hearth]

bortle 8

I'm in bortle 7 and I can hardly get the core on most nights

[dusty gull]

I've just downladed the pix/rc trial versions

Wow

It's great

Really intuitive, in 15 min I have everything I need

[dusty gull]

This is a really quick process

Kinda surprised with only 30min integration

[burnt bay]

That looks so sick

[burnt bay]

Is this the Cigar Galaxy?

[dusty gull]

Yes

[burnt bay]

How did it look visually, could you see it with the 5”

[dusty gull]

Yes, I can clearly see it's shape

[burnt bay]

Nice, I plan on going after it next clear night

[upper pasture]

30 minutes Pleiades, Stacked and processed in SiriL by someone in another astro server. It's not the best data but I've only been doing this for a few weeks. Using my unmodded canon t3i.
Thoughts?

[dusty gull]

Nice! I've never been able to pull out so much nebulosity untracked

Could you share the stacked file?

I think there's something to improve in terms of denoising

[upper pasture]

The unstacked and stacked is in #1064478536255164476

[dusty gull]

And first process of 20min on ngc 891

[upper pasture]

I might have been slightly out of focus, I also do plan on collecting more data.

[upper pasture]

Looks nice

[little prism]

good stuff

[upper pasture]

Should I post the link in here?

[dusty gull]

Thanks I've seen it

[upper pasture]

Looks epic

[little prism]

oh thank you :D

[upper pasture]

I never knew Barnard's loop would be that visible at just over an hour.

[little prism]

I did not know either

I mean it was f3.8 but still

[tame jetty]

6 minutes bortle 5 samsung S20 and 20x50 binoculars

[little prism]

dude thats so good for b5 and phone

nice

[tame jetty]

thaanks man

as soon as the weather gets better I'll try andromeda

[little prism]

I'm looking to add data, Maaybe even today but there are slight clouds so I don't think it would be worth it

[upper pasture]

im collecting orion data rn

[dusty gull]

@upper pasture

[little prism]

you can see the clouds

(thats a live cam from my local observatory )

not really worth it right?

[tame jetty]

could take like 20 minutes of data instead of 6 really make a big difference or would it be minor?

[tame jetty]

Maybe they'll disappear in aa while

[little prism]

yea it would do a difference

and from 6 to 20 min is gonna be good

[little prism]

idc I'm setting up

even it is only like 10min worth of data

[tame jetty]

this means 300 subs

it will take a very long time to process lol

[little prism]

alr I'm imaging

[tame jetty]

good luck

[little prism]

ah orion is pretty much in the clouds right now but should get clear in like 5 min

hopefully xD

[tame jetty]

sure, those clouds usually move pretty fast

[little prism]

I'm adding more data to this

4s subs

I don't have any trails with that so it's ok

[tame jetty]

which is already pretty impressive

[tame jetty]

which focal length is it?

[little prism]

it was shot at 50mm

[tame jetty]

I have a canon 400d with the kit lens. i would like to try and take some data

[little prism]

you should

It will be better than the phone

[tame jetty]

but it is a nightmare to focus and the only way to take steady pictures is to set a 10 sec timer

bc I don't have an intervalometer

[little prism]

yep

3s is enough

[tame jetty]

so it would take forever

[little prism]

its a pin in the behinds but it works

[tame jetty]

it has only 10 sec...

[little prism]

this was untracked without a intervalometer

[tame jetty]

and also gimp can't seem to read the raw file...

[tame jetty]

quite detailed

[little prism]

yea see its possible with great effort

[tame jetty]

how much data?

[little prism]

like 16min I think

[upper pasture]

Sorry, I didn't see your ping. I love it, Thanks for the process!!

[dusty gull]

Ok I'm REALLY not happy with this process but the data has some potential

I'll spend more time on it tomorrow

[calm hearth]

looks incredible

what setup do you use?

[dusty gull]

The 5 inch dob f5 and asi 224 mc as usual

But I really screwed the process

It has a lot more potential

[calm hearth]

"really screwed the process" here I am trying to get a faint hint of the ring nebula with my 8" and 178mc which has a larger sensor

do you have any suggestions to make the experience a bit easier? Such as finding objects?

[little prism]

autostratch alr shows me I was out of focussss. Only 17min tho. It was more like a test because clouds where about to roll in

so I'm not mad about it. but I know know that it is worth it trying to get like an hour or smth

[dusty gull]

I can try to help you but tomorrow (I'm going to sleep)

Don't hesitate to remind me if I forget

Also LMC can give you some advices

[gentle birch]

bortle 8 for 15 minutes

[gleaming walrus]

Wow for B8 this is great

2 mins from B3 to 4

[upper pasture]

I have 50 minutes of unstacked Orion Widefield data lol

[little prism]

stack it pls @upper pasture

[upper pasture]

I cant stack lol

[little prism]

can you send me the data?

like over google drive

[upper pasture]

Sure, should i make a share data post or send in dms?

[little prism]

you can do a share data

and include your calibration frames if you took some

[upper pasture]

Will do

#1065277218487545917

[little prism]

why can't you stack @upper pasture ?

[upper pasture]

I have a chromebook, and I can't install the software on here

[little prism]

damn

but you can process it right?

[upper pasture]

Kinda, I can only use web based editors tho

I use Pixlr.com and Photopea sometimes

[little prism]

eh re you sure you sent everything @upper pasture

I have everything and its like 16min data

and I cant stack the tif with it

@upper pasture are you there cause idk if I want to stack it now or not. You have to tell me

[upper pasture]

I think i sent everything

sorry i was out

i just calculated and the one folder of lights should have 37 minutes

and the other should have the rest

[little prism]

how many light frames do you have

in your folders

[upper pasture]

50 each calibration frames

[little prism]

no

light frames

not flat

[upper pasture]

oh shit my bad

uh

[little prism]

no problem

[upper pasture]

i think it should be around 750

[little prism]

huh

well I got 250

smth went wrong

[upper pasture]

i posted 2 links for lights

[little prism]

oh shi I know why

it's all my bd

I was not loading all the files in drive

I just selected all but most of them were not even loaded

I'M sorrry

[upper pasture]

ah lol

you're good

[little prism]

nah I'm so stupid

but I can't the 20min tiff

thts sdly not possible

[upper pasture]

that's fine

[little prism]

well downloading all of that will take a bit longer

[upper pasture]

yeah lol there's about 20gb of data

[little prism]

holy shi it is downloading them in multiple zips of downloads because its so much

yea this is gonna take while. Downloading is gonn take like 35 mins and than 1 hour stcking or so

[upper pasture]

Okay, Thank you.

[little prism]

@upper pasture i got some news

I have downloaded everything 100%

sadly there where some duplicates so you have a total exposure time of 48 min and I'm stacking now

[upper pasture]

Okay that's fine!

[little prism]

@upper pasture guess what

[upper pasture]

wassup

[little prism]

its finished

[upper pasture]

Awesome

[little prism]

I'm sending it to you

in a few secs

[upper pasture]

Alright, thanks

[little prism]

https://drive.google.com/file/d/1lyX0WlcLFlWRksWVBC_MFtxrR42DTHuj/view?usp=sharing

here you go

[upper pasture]

Thank you!!

I'll see what I can do in the process

The editors i use are so shite lol

[little prism]

or post it in #1021002743080558642 I'm sure someine will be kind enough to five it shot

I'm bad at processing too so yea

[upper pasture]

Yeah I posted in #1021002578588352572 i think that should be fine.

[upper pasture]

Lol you're good, Thanks for stacking tho!

[little prism]

no problem

[upper pasture]

I might shoot Andromeda Galaxy untracked tonight, If clouds go away

[little prism]

I tried that too. More as a test and i was out of focus xD

[hybrid basin]

My newest picture at 85mm. It were only 6min and a heavy crop, but I hope, that the 25min of Rosette, I also collected today, look better.

[gentle cipher]

that doesnt look like rosette

that looks like m33

[hybrid basin]

Yes it is M33, but I also collected data of Rosette, and I hope that will look better.

[gentle cipher]

oohhh, i misread that

[gentle birch]

acquisition?

[hybrid basin]

What do you mean? It looks bad, but for me its progress, because last time I tried M33, I shot the wrong "star".

[gentle birch]

no i'm asking for the details of capture

focal length, aperture, shutter speed, ISO, gear, etc

[gentle birch]

don't worry bro that happened with me for andromeda idk how i missed a naked eye DSO😂

[hybrid basin]

Oh, sorry, I didn't know, what that word meant. The Details: 85mm, f/1.8, 1,3sx1200s, ISO 5000 (yes, I forgot to turn automatic off), Nikon Z50, Sky: B5

[gentle birch]

oh so you took untracked?

i knew triangulum was bright but not that bright

[gleaming walrus]

Work in progress 3hrs+ of untracked data mostly from B7

750d or T6i with 50mm

Total of 8 sessions,
1 from B4 and 1 from B5 to B6

Rest all from B7(home)

[dusty gull]

Really nice!

[dusty gull]

I really can't find a process I'm happy for...

[little prism]

what are you processing

nah come on man

[little prism]

Wait am I stupid... which messier is that

[dusty gull]

No I just forgot to post it
M81

[little prism]

damn thats pretty good for untracked

[little prism]

whats the total exposure time

[dusty gull]

1h and 15min

11000 subs

I aim to get 25k, as well as on M82, ngc 891 and M51

[little prism]

dmn

tha's crazy

[gentle cipher]

If I did that with my DSLR it's gonna be dead real quick

[dusty gull]

Astrocams supremacy

[gentle birch]

how many frames? It's my dream to take rosette untracked

[gleaming walrus]

Exactly don't know,
I took on several days so need to check that

Total exp time was 3h 49 mins 32 secs

Stacked all the files which was already stacked daywise in sequator,

I need to try pix for individual days and gonna combine since I didn't delete the raw files

Most probably 4 secs per frame

[gentle birch]

at which point would you stack the final frames from all the nights?

right after stacking individually? after all post?

i'm trying to shoot over nights but i'm confused

[gleaming walrus]

I also don't know how others do,

I stacked and kept the tiff files daywise, then done the stack of these tiff files in DSS

This was my first and last multi day capture until now

[gentle birch]

ah ic

[gleaming walrus]

Captured in between 2021 nov to 2022 feb

Now only stacking those 😅

[short galleon]

Took this last night

[dusty gull]

Quick process of some m13 data

[gentle cipher]

how are you doing m13

m13 is extremely out of season

essentially impossible

[midnight flower]

isnt it in southern hemisphere

its either he is in a place where its there, or he stayed up to like 2am to image it

or its old data

[gentle cipher]

hercules is even less possible in the southern hemisphere

its a northern targetr

[crimson fractal]

10 degrees at max

[midnight flower]

he prob living in canada

or a northern european / asian country

[burnt bay]

what

it rises to ~40° before sunrise

From northeast US

wait no like 50°

It’s very doable it’s just a morning target

[gentle cipher]

really?

im 42 degrees and it only gets to like 10 degrees before sunrise

[burnt bay]

Huh interesting

[gentle cipher]

ohh nvermind

that was a month ago

im so outdated

[gentle cipher]

woww cygnus is at 10 degrees before sunrise

[burnt bay]

Hype for Ring Nebula

Might try it in the morn if sky is ok

It gets to like 30deg before sky is too bright

[gentle cipher]

Vega should be coming back right

yeah

[dusty gull]

It rises in the morning

[dusty gull]

I'm really surprised of this result as it's only with 2 min data

[little prism]

you are crazy

[calm hearth]

insane

I can't even get the ring nebula with almost double your aperture

[dusty gull]

What's your camera? (sorry if I already asked but my memory isn't very operational)

[hybrid basin]

1h of hearth and soul. It could have been worse. I posted the data in share your data, as always. I hope to do a better edit later.

[dusty gull]

And reprocessed the old data (don't remember how much it was, around 10min probably)

[calm hearth]

ZWO ASI178MC

but I think the main issue is that I live in bortle 6.6

almost bortle 7

[dusty gull]

Yeah it's quite an issue

But I shot the ring in B7

And you can still do some things

What is your scope focal ratio?

[calm hearth]

F/6

[dusty gull]

And what fl exactly?

[calm hearth]

1200mm

so it's 1200mm, 203mm aperture, at f/6

[dusty gull]

OK ok

So

Wait a minute

Use the npf rule first

So multiply 0, 1371 by the inverse of the cosinus of the declinaison of the target

[dusty gull]

This will give you the right exposure time

You can multiply by ~ 1,3 without any bothering star trails

[calm hearth]

ah

I got 0.3s

for the orion nebula

[dusty gull]

Ah that's weird

Should be ~150ms

[calm hearth]

oh

maybe I used the wrong declination

[dusty gull]

It's 5°

For the settings, set the gain at around 4/5 of the max gain
Adjust offset (or brightness, same thing) so that none of the histogram is clipped

Then capture as much frames as possible but there has to be enough stars

To align

[calm hearth]

ok

do you think I could get C/2022 E3?

[dusty gull]

I'm processing it, I'll show you the result

But I think i'tll be quite hard

[calm hearth]

isn't it like magnitude 6?

[dusty gull]

Yes but its big

And even tracked, comet are hard to capture (because they move)

Here's what I got

(I can probably make it look better)

[calm hearth]

looks incredible

I'll give it a try tonight

[dusty gull]

Well good luck!

This is 2000 * 350ms subs

[calm hearth]

what software do you stack in?

I use ASIStudio but it seems to get rid of a lot of detail

even bright areas are completely removed for no reason

I tried stacking in siril but it produced really weird star trails

[dusty gull]

Siril

The best for this kind of stuff

(untracked)

And processing comet is kinda different, I'll tell you how if you want

[dusty gull]

Weird

Wait a few minutes

[little prism]

My tracker hopefully arrives at Monday so I'll be leaving this forum soon... But the weather here in Germany is soo bad that I don't think that I'll be able to use it for the next like 2 Weeks... I just hope I have the change to see the comet

I love this

[hybrid basin]

I had some clear weather yesterday, but I had to throw some hundred frames away because of clouds 😭 instead of 2h I got only almost 1h

[little prism]

what did you image
