Untracked Astrophotography

[sterile violet]

Oh no, it isn't the 👿, it is the 😈

[midnight flower]

my bad lol

[sterile violet]

lmao

amazing, maybe a little too long sub exposures

[midnight flower]

yeah ik

[midnight flower]

I did 6"

prob bump it down to 5"

actually wait, I am getting a tracker hopefully today

so nvm

[sterile violet]

nice

[tight vine]

Gonna have a go at ap again.. This time i hope its not gonna go horrible, goal is the pleiades I got a sturdy mount with a 16 year old (i think) dslr with a 55-250mm ed lense, any tips on how i can get the picture to have detail?

[sterile violet]

mod it

also use the lowest f ratio

and longest exposure you can as it is super faint

[midnight flower]

do 100mm, 4-5s exposure

[midnight flower]

modding isn't very important for pleiades

[sterile violet]

yeah ik but it will help

you could tr to frame it with the California

[tight vine]

its old, doesnt have an ir cutfilter

[tight vine]

its 61mm aperture btw

[sterile violet]

old cameras dont have them?

[tight vine]

No this one dont

[sterile violet]

i mean just try tour best is all i can say

do the longest exposure you can

and good luck

[tight vine]

I dont know my sensor size.. not full frame tho its like a pentax k10d (highest iso it can do is 1600)

[sterile violet]

google it

[tight vine]

used a calculator before apparently its like 2 seconds

[sterile violet]

what is

wait are you tracked

[tight vine]

nope

[sterile violet]

oh

[tight vine]

also its APS-C

[tidal tide]

how did he even pull out that much detail

[midnight flower]

guess my data was decent

[tidal tide]

he's just a magic man

[midnight flower]

I want him to be my mentor

once i get pix

[gentle cipher]

he's god tier

this is my image, untracked unmodded 135mm 20 minutes processed by @sterile violet

HOW IS IT SO GOOD

it looks like several hours

hes just so good

[hallow tapir]

Untracked. Lagoon and trifid

[tidal tide]

Untracked Orion with a hint of flame and horsehead

[hybrid basin]

7min cropped untracked Andromeda with 300mm f/7.1 lens. It's worse than my last pic of M31. I think the 300mm lens isn't so good for objects like that, because aperture is to small. The stars in the corners look a bit weird.

I hope I get a camera without mirror, because I don't think it's so good for the camera to take so many pics.

Then I can take thousands of pics without worrying about the camera

[tidal tide]

camera shutter usually last a very long time but mirrorless will still last longer, that comes at a higher cost though

[hybrid basin]

For me is the weight also important, because I still want to use it "normal". But I think if I still like this hobby in two years or so, then is a dedicated astronomy camera the best choice anyways.

[tight vine]

Does field rotation get compensated by stacking or do i have to do smth about it

[tidal tide]

doesnt really compensate, it just lines them up so the rotation will still be there, the sensor in my camera can rotate so i can somewhat compensate but usually it isnt so extreme that you have to.

[sterile violet]

its not in focus

[real furnace]

I guess is it just chromatic aberration

[sterile violet]

look at m42

[real furnace]

If it is out of focus, i think it is pretty close

[tidal tide]

it'd be slightly out of focus then, orion is a blur because im rather sucky at processing and due to my exposures being a bit too long, getting the core details well at 100mm untracked won't really work

playing with RGB compositioning in Siril is pretty fun, all sorts of funky colours

[gentle cipher]

that looks like a colorblind image

[tight vine]

Is 6 minutes of integration with a 62/250mm f6.3 ed lense enough for pleiades or should i do more lol

[strange seal]

F6.3 you are gonna need wayyyyyy more time. I would estimate 20 minutes before you get hints of it and a couple of hours before you get a half decent picture.

[tight vine]

Hints of the nebulousity you mean?

[strange seal]

20 minutes will get you hints of it. Not an image really. A few hours will get you an image.

[dusty gull]

Here's what I got with around 20min at f6.3 @tight vine

[strange seal]

Bortle?

That’s more than I was expecting lol

[crimson fractal]

pleaides dust is quite bright

[dusty gull]

bortle 4

But pretty low so idk

[strange seal]

Cool.

[strange seal]

I guess I never tried it more than a few 5 min subs

[dusty gull]

Also the A7III is pretty good I beleive

[crimson fractal]

30s subs f11

[tight vine]

I see

[tight vine]

Just realized that all my exposures were out of focus

Maybe ill do orion instead

[tight vine]

U recon andromeda is easier?

(like way easier i mean)

[dusty gull]

Definitively

Same specs, but a bit more integration time (maybe 30 min total?)

[tight vine]

Alr what focal length do you think is good

100mm? (f4.5~) or lower/higher

[dusty gull]

I can still get some details at 55mm

Higher fl meens slower lens and shorter subs...

So try different fl until you find the right balance between details and signal

[tight vine]

Im just gonna try 35mm and get cassiopea in aswell

gonna do 25 minutes at f4

15 secs each

b3 (i think) skys should make it easier right

[dusty gull]

Yes sure

[dusty gull]

Mine were 3s

[tight vine]

npf rule is 16.5 sec at my spec but im doing 15

I dont have an intervelometer with me so im doing it by hand rn

atleast the tripod is like 0 wobble and the button rlly rlly easy to press

did a 30 sec test exposure aswell and the view is nice

hope i dont screw up the edit like last time

My tripod has a wedge built into it

nice addon

well ok im doing 100 15 sec exposure
how many flats darks and bias do i need

like 20 of each or

[dusty gull]

Yes that would probably be enough

Maybe a little bit more darks/bias?

Idk

[tight vine]

good cus my camera died after 20 darks and i forgot battery charger

luckily during bias and lights nothing has to exactly match

[sharp heath]

Thanks lmc for helping with this image. 90x4s 50mm f/1.8

[tight vine]

triffid and lagoon peeping in the corner

[sharp heath]

Yep

[tidal tide]

darks dont really help with DSLR's because the temp changes too much

[tight vine]

I did it outside tho?

and it was a steady temperature

it was 13 C the entire time

[strange seal]

Yes

[tidal tide]

load em into ASTAP and analyse, the sensor can still change temps

i've stopped using darks and there's 0 difference when i use them or dont

[sterile violet]

at least I tried, Sculptor galaxy using a 75-300 kit lens ~ 25min exposure

I need a lens with bigger aperture

[hallow vortex]

that looks oddly bad for a 75-300 kit lens

I did 50mm

and it looked better res

ohh

nvm

Didn't read sculptor gaalaxy

for what it is it's not too bad then

[sterile violet]

I think the lens has a defect like misalignment or astigmatism, when I try to focus the stars are not round they look like a bean

[hallow vortex]

ahh a lil weird tbf but it is a kit lens

[sterile violet]

I also have a 135mm super takumar but i dont have an adapter

[void condor]

Really liked your image so I had fun practicing my editing it, what do you think?

[void condor]

I’ve got a better one

[tidal tide]

https://www.mediafire.com/view/7nsxwg4rlnns5oe/no_object%252C_2022-10-30%252C_1384x2L%252C_K-3_stacked.tif/file

edit that, editing a PNG doesn't really do much

[real furnace]

i think that's the wrong file lmao

[tidal tide]

nah, it's correct, i cant even do planetary and the file is 277MB + the name is still the output from ASTAP

[tidal tide]

doesn't show that anyone has downloaded it either

[real furnace]

that's strange

i restored it from the trash bin and it is normal now...?

[tidal tide]

huh 💀

[sterile violet]

looks out of focus

[void condor]

Well I was just trying to get the nebulas more apparent

[tidal tide]

try the raw data

[void condor]

I guess I could

[hallow tapir]

That’s nice but when you zoom in it kinda has quite a lot of noise

[sharp heath]

Yep

It’s because of background extraction

[strange seal]

background extraction doesnt put noise in, just exposes it wile making data better

[midnight flower]

if background extraction makes a image worse

dont do it lol

or manually do it yourself

[sharp heath]

i manually do it

[sharp heath]

Make it better

Brings out some dark parts

[hallow vortex]

what is this

Milkyway?

[tight vine]

Yes no sht

[swift warren]

i'll just drop this one here after the fact cause on all my other devices forums and threads do not work

[tight vine]

I just realized i did 20 minutes of darks on a 50 min lightframe shot for nothing because it somehow switched to jpeg and vertical image

do i need darks or can i just scrap then

also what to do when cam doesnt have hystogram

[swift warren]

exposure tests beforehand and a working knowledge of how EV relates to camera settings?

which would be way easier on the digital side since you don't have to put up with reciprocity failure

[tight vine]

Found my cams histogram but its not very helpful or im doing it wrong

[midnight flower]

for your flats

go on AV mode

[swift warren]

i don't do darks, the concept of image sensor thermal noise doesn't exist where i'm from (and the sensor on my scanner will always operate in a controlled environment!)
but i should do flats/bias

[tidal tide]

Not much point in taking darks for DSLR's, sensor temp varies so they wont help and might even make it worse.

[mint merlin]

1.10 hours. Planning on 2+

[void condor]

Nice job for untracked

[sterile violet]

Well done

[mint merlin]

I need more nebulosity

[hybrid basin]

How do you get so much time? I mostly set the exposure time only on about 1s and so I need many shots for so much time. But I don't want to destroy my father's cam because of taking to much pics😅

[tidal tide]

a lot of subs probably

[tidal tide]

what fl and f ratio?

[mint merlin]

135, F/4.5

[mint merlin]

Just clear skies and some luck ig

[hybrid basin]

Ok I hope there's a chance in the next month

[tight vine]

Does anyone know why my DSS isnt accepting my lightframes

Bias and flat worked

but when i select all my lights and press open nothing happens lol

[compact dust]

North America Nebula 400 2,5s subs F=2,8

I did make it colourless because it had this strange green

[tight vine]

Why does my DSS say my pics arent compatible
it says width length number of colors number of channels and only one masterdark,offset,flat
wtf

how do i fix this

[compact dust]

Do you want to stack pictures from different nights?

[tight vine]

no but my flats and bias are set to 2006 cus my cam randomly turned off after i wanted to start doing my flats and bias so idk

if thats the problem then im probably fricked

is there like a fix for that or not

[tidal tide]

green is common with DSLR's, just a background neutralization should do the trick

[compact dust]

Can i do this in dss or gimp?

[tidal tide]

Siril

it's a free program and is pretty powerful

[sterile violet]

with my samsung S10 and crappy tripod

20m of data

[compact dust]

Is there any way without using siril?

[dusty gull]

Why?

Siril is great

[compact dust]

I don't get along with it

[hallow vortex]

You can do it in DSS

@compact dust

I think at least

At the end where you have the output mess around with the RGB sliders until it looks okay

[compact dust]

Ok thx I will try it

[tight vine]

does anyone have a fix for this??

[tidal tide]

it's simple though

[tidal tide]

maybe they arent the same bit depth, maybe put both to 32 or 16

[dusty gull]

They need to have all the same bit depth, dimensions, channel number (aka mono or color) 1nd same file format I believe too

@tight vine

[tight vine]

uh

ohh

just realized

my last 3 lights are JPG for some reason

ill just delete those

right

now its working

oh sht

my pc fan is going crazy

[tight vine]

When i try to open my autosave.tif file it gives me

tiff picture warning
unknown field of 5000 (0xc350)

and then it opens a fiel that doesnt look anything compared to the actual thing dss showed me

just fixed that

but why does the tif file look so vibrant and full of stars on DSS but on normal photos app and gimp it looks so dimm and boring lol

[mint merlin]

gonna do a crap ton of reedits

[compact dust]

I think i am gone leave you guys

Today my eq1 with a tracking motor came

[tight vine]

i dont think thats very reliable

[crimson fractal]

its a start

[dusty gull]

It should allow short but still greater than untracked subs

Also easier to take a lot of them than when you have to reframe every 2 min

[sterile violet]

nice

im getting a SWSA at Christmas so i will leave soon too

[compact dust]

At 135mm focal length i can easily take 15s subs

With good alignment and everything 20-30 should be in

[sharp heath]

Uranus and the moon

[sterile violet]

🤨

[sharp heath]

bro

[midnight flower]

Lagoon Nebula + Trifid

very wide field shot

it is located close to the center of the milky way

[hallow vortex]

Ahh I was going to say it looks more like MW

[dusty gull]

Express process of tonight's Orion, ill bring the color back tomorrow

[sharp heath]

north american nebula

[gentle cipher]

Criticism?

is the background too bright

[tidal tide]

a bit yes

[gentle cipher]

i forgot to save the starless for editing

[sharp heath]

Looks good tho

[sterile violet]

in PS you can select using color range>highlights and then do a levels adjustment on the background to reduce the brightness

like this

[gentle cipher]

i dont like that

[sterile violet]

f

[mint merlin]

mind sending data in #1021002743080558642?

[gentle cipher]

Sure

[sharp heath]

You could prob do longer subs

[hallow tapir]

Orion Nebula I just got a call

[crimson fractal]

whats his number ?

[hallow tapir]

000

(It’s a joke dont call it pls)

[crimson fractal]

i obviously recognise that number :v

[hallow tapir]

just making sure

Rate this old milkyway photo

oh sorry wrong person

[sharp heath]

say "Okay" if you love LMC

[hallow tapir]

Okay 👍

[hallow tapir]

that’s untracked

[sharp heath]

yes

[hallow tapir]

wow nice

that’s cool

[tacit grove]

bias frames next time

[dusty gull]

@sterile violet would wind having a try at my M81 data?

There isnt much here (only 5 min of data lol) but I'm curious on what you can manage to do

[prisma plaza]

is this tracked?

and which bortle?

[dusty gull]

B4 untracked

[prisma plaza]

okay

[hallow tapir]

Edited by 20o

[midnight flower]

200 master processing at its best

[hallow tapir]

i think its quite good for 5 mins

soon once it’s clear, I’m gonna do like 30-40mins bc my intervalometer finally got fixed so I can take nice longer wide view exposures

[midnight flower]

did u not use magic lantern

or can ur camera not support it

[hallow tapir]

My dslr doesn’t have a inbuilt intervalometer

[sharp heath]

What camera is it?

[hallow tapir]

5dmarkiii

[sharp heath]

I’m pretty sure you can get magic lantern

Just make sure it’s on the right version so you don’t mess up your camera

[sterile violet]

Credits go brrrrr

[sterile violet]

[gentle cipher]

Criticism?

[radiant kestrel]

Actually pretty great-

What fl?

[dusty gull]

Maybe a bit out of focus?

Otherwise very good for untracked

[radiant kestrel]

I think the focus is fine, stars are actually quite crisp all things considered

They're just never going to look amazing untracked

[gentle cipher]

135

[gentle cipher]

no bahtinov so i got it as close as i can

[radiant kestrel]

Well yeah it looks pretty great all things considered-

[gentle cipher]

I'll probably diy a bahtinov mask later

[mint merlin]

Just remove al the stars and nobody will notice if it’s oof

[lavish linden]

This was my second deep space image ever. (m81 & 82)

• Taken back in April
• Untracked (obviously)
• Nex 5
• 210mm at f6.3
• Bortle 8
• 1hour 18 minutes

[mint merlin]

bodes and cigar?

[lavish linden]

Yep forgot to say that

[mint merlin]

this was my shot back in feb

[lavish linden]

[prisma plaza]

6 minutes from bortle 7
Nikon Z 50 , 250 mm
1.6 seconds subs

[gaunt meteor]

My camera doesn’t like nebulas for some reason so I took this with my phone 2-3 second exposures I think I stacked like 20 of them

[sharp heath]

Is this jpeg?

[compact dust]

What do you mean with your camera doesnt like nebulas?

[little prism]

what happend here. Is smth wrong with my camera ? xD(just a quick process cause I wanted to show the image)

[tidal tide]

maybe try background extraction and SCNR in siril, should fix it

is it with flats or no?

[little prism]

yes it is

and for some reason my siril is broken and I can't use background extrction

the "apply" button is just grey

and yes I pressed "compute background"

[tidal tide]

where are the markers?

[tidal tide]

edges could be overcompensating due to flats being too bright

[little prism]

is this better?

[tidal tide]

yep, core is orange now though, messed around with rgb compositioning?

maybe photometric colour calibration could help

[little prism]

wanna show me how its done? I can send the utosave in share your data if you want

[tidal tide]

im not too great at processing myself, just trying to suggest stuff, but you could put the link here too

[little prism]

https://drive.google.com/file/d/1qeyGglMKunn_GAsYbQJzJG_l_2fqPrro/view?usp=sharing

[tidal tide]

i'll have a go after i finish some of my old data

[little prism]

alr

[tidal tide]

didnt do much stretching because i wanted the core to not be blown out but yeh, im not good at this

[little prism]

but the colors look way better than on my pic. Ty :D

[gentle cipher]

hdr

[tidal tide]

shhh, i forgot

[gentle cipher]

guess ill do it

the folder expands

[little prism]

haah thank you :D

I got my won personal folder

@gentle cipher very kind from you

[gentle cipher]

@little prism almost done

[hallow vortex]

Literally me

I have a folder for Kerbal he was the first

[little prism]

@gentle cipher nicee

[gentle cipher]

1tu's folder was the first for me

[hallow vortex]

How many gigs total for all that

[gentle cipher]

1tu folder

[gentle cipher]

Only 6.52 for every folder combined

[hallow vortex]

oh thats not bad

I think thats more or less what Kerbal's total takes for me

nvm no

I deleted some

it's 5.3gb

[little prism]

@gentle cipher can you even get "good" data out of this. I mean it was like idk maybe 5 min total exposure before clouds rolled in xD

[gentle cipher]

i highly suggest getting more data however i have finished

[little prism]

yea ik xD

I'm planing on making a little protect on orion for the next month or so (if it finally clears up because it's been cloudy for the past 2 weeks) I wanna maybe get like 30 mins or smth and get my first flame and horsehead. hopefully

[little prism]

ohh nice I'm excited to see the pic

[hallow vortex]

My plan when I get to spain as it'll be B3 with no lights nearby for a few km

[little prism]

damn B3

[gentle cipher]

@little prism

[little prism]

I'm blessed with B5 and the capital state right next to me

[little prism]

woow. the colours

And I like how the core is still good looking :D

Thank you @gentle cipher !

[gentle cipher]

you're welcome

more data helps a lot

[little prism]

next time its gonna be more I promise xD

[little prism]

yea and maybe I should try not shooting at the max focal length because those weird distortions were not there in my other pics

[tidal tide]

im guessing you shot with a wide open aperture while at that focal length? if so it could most likely be the cause of the distortions

[little prism]

yea f2.8

and focal length was at its max (600mm)

[tidal tide]

600mm f2.8, what sort of chonky lens is that

[little prism]

ehh

bridge camera lens

25-600mm f2.8-f11

[tidal tide]

damn, thats a wide range

[little prism]

and everything else you can read here: https://www.panasonic.com/mea/en/consumer/cameras-camcorders/lumix-digital-cameras/dmc-fz300.specs.html

[little prism]

ik but does that look like 600mm

[gentle cipher]

for the orion image

does not look like 600mm to me

[tidal tide]

looks more like 300mm to me

[little prism]

yea I'm thinking the same. But it is at 600mm

[tidal tide]

maybe some weird crop factor, if it even has one

not sure

[little prism]

zoom test with that camera

[little prism]

eehh "CMOS-Sensor 1/2,3" 6,2 x 4,6 mm (Cropfactor 5,6)" thats

[tidal tide]

thats a small sensor, guess that might be why it says 600mm

tried getting jupiter or saturn with that thing?

[little prism]

btw @gentle cipher what did you use for processing

[little prism]

yea I tried jupiter and you can see one of his moons with the right settings. But its still like small and not worth really capturing

[gentle cipher]

pixinsight, siril is much better for beginners

[tidal tide]

only 1 moon?

[little prism]

yea thats all I could see

[tidal tide]

damn you got pixinsight?

[little prism]

but it was in live view. I don't really know how to photograph plantets

[tidal tide]

planetary is usually videos with high framerates if i remember correctly

[gentle cipher]

yeah

[tidal tide]

i have the trial version but cant figure anything out

[gentle cipher]

do you speak siril?

[tidal tide]

yes

i think

[gentle cipher]

pixinsight is just light mode siril

[tidal tide]

the buttons are all so scattered though

[gentle cipher]

They hnestly are

[tidal tide]

it feels like a transition from tinkercad to fusion360

[gentle cipher]

pov pixinsight

[tidal tide]

crazy amount of options

[gentle cipher]

@tidal tide this video is how i got started outhttps://www.youtube.com/watch?v=CZSVCNX8Ow8&t=1931s

[tidal tide]

god, i just want it to get clear before my pix trial ends so i can at least freakin try it

[gentle cipher]

that video will help a lot

[tidal tide]

def wont help with clouds

[little prism]

xD

[little prism]

yea same for me. It has been cloudy for the last 2 weeks and it's supposed to be cloudy for the next 2 or so

[tidal tide]

been cloudy for the entire month and itll probably continue into december

i wish i could just blow them away

[gentle cipher]

@tidal tide https://www.firstlightoptics.com/latest-accessories/zarkov-cloud-gun.html

[little prism]

imagine that would work

[gentle cipher]

it does

[little prism]

AHH

[gentle cipher]

you need some zarkov cloud gun

[little prism]

do u use it

[gentle cipher]

no too poor

[crimson fractal]

Y I have a folder

[gentle cipher]

From that one Pleiades

That I still need to process

I'll get around to it eventually

[mint merlin]

i may not be untracked anymore but ill still stay here

[sterile violet]

blueshift has joined the chat

[hallow tapir]

smc

[sterile violet]

orion tonight for the first time with my camera lads

[little prism]

lets gooo

i'm staying hyped about the image.

[little prism]

progress so far

[tidal tide]

maaaan i need clear skies

[little prism]

the last pic was last month xD

like 2 weeks ago

[tidal tide]

still, i saw the blue sky peak out of the clouds for 10 min today but that was all

[dusty gull]

There have been clouds and clouds only for 3 months

I'm dying

[little prism]

FR

bro it's so bad here in Germany

[tidal tide]

aint much better in estonia

just wanna make the clouds go boom

[little prism]

fr

[timber folio]

pleiades not plejades

great progress though so far

[mint merlin]

plejades

[gentle cipher]

forums got an udpate

[gaunt meteor]

I think it’s because my camera doesn’t let me control exposure or exposure time so all I see is the stars in and around Orion.

[gaunt meteor]

Yea idk how to change it to raw

[dusty gull]

I gathered 20 min on the crab, can't wait to see!

[sterile violet]

both 15m in a b7

[hallow tapir]

i

[radiant kestrel]

The California and m45 one is p great all things considered

[timber folio]

are you going to process these

looks like good data for untracked

[tidal tide]

reprocessed some old data with pixinsight, photoshop and noisexterminator

[compact dust]

Wich cam do you use?

[sterile violet]

I have

[sharp heath]

What phone

[gaunt meteor]

It’s a iPhone 11 Pro

[gaunt meteor]

https://a.co/d/i8DDqza

[dry spade]

If the sensor is poor and it only outputs compressed data (MJPEG or YUY2) then all the faint detail will be discarded when each frame is compressed. It's near-dark, so it gets compressed to black.

[timber folio]

needs cropped and scnr

[sterile violet]

what do you mean

[timber folio]

it needs processed more

thats just autostretched and exported

[sterile violet]

no it isnt, but feel free to do a process on it

[sharp heath]

I have same phone there is some apps the let you like. NeoShot but max is a 1s exposure

[void condor]

I’m currently untracked but I’m on track of getting a tracker this year

[gentle cipher]

same i hope

if i can find a good deal on a tracker, then I can get one for christmas.

[midnight flower]

just dump your savings into the christmas fund

thats what I would do for a tracker

[gentle cipher]

doing that

im paying shipping

because I'm broke

[midnight flower]

20 bucks 💀

shipping on amazon is literally free anyways

or on some astronomy sites

[gentle cipher]

no im going used

[midnight flower]

what mount

[gentle cipher]

eq3 or eq5 class mount

depends what i can find, found an eq5 for $150 the other day but it sold

I found another eq5 which im going after

[sterile violet]

30m of data in this quick edit in siril

i will edit properly when i get home

full moon

[gentle cipher]

That's so good for full moon

Do more Cygnus

[sterile violet]

tomorrow?

[gentle cipher]

Do cygnus before it's 100% out of season

[sterile violet]

it took 1h to stack the frames

i mean i could take more i guess

[sterile violet]

should i do it again?

and add the data tomorrow

i can do an hours exposure

[gentle cipher]

There's lots to do in cygnus so find a target

Add an hour of time and good image

[sterile violet]

do i just need to make sure my framing is the same?

[hallow tapir]

idk what this weird image is

its quite cursed

[strange seal]

Just a bit

[sterile violet]

100% moon, b7 and 30m of exposure

[hallow tapir]

do you know how i could fix it?

[strange seal]

you cant fix it

shoot without the moon and get more time

[hallow tapir]

would like 2-3h be alr?

would that make horeshead visible?

[sharp heath]

I wouldn’t mind having a go

[midnight flower]

looks like lagoon

idk though

[dusty gull]

Nah orion I think

[midnight flower]

wait yeah its orion

you can see horse head and flame although weird as hell

[hallow tapir]

idk what went rong

anyone care to process it for me

ill send the unprocessed ver

[radiant kestrel]

It looks overstretched

That combined with either too much or not enough noise reduction

I'm guessing too much

[tidal tide]

Looks like compression, barnards loop is coming out there even

[radiant kestrel]

Yeah fs

Oh yeah I'm sure there's a compression issue

Its also definitely has been overly noise reduced as well

Looking at it again

[hallow tapir]

e

[hybrid basin]

2,5 min of untracked M31 with Nikon Z50 and 85mm f/1.8. It was to cold for getting more data (so I have no calibration frames). Quick processed in DSS and Siril.

[tidal tide]

85mm and f1.8, that's one hell of a lens

[gentle cipher]

2.5 minute or 25 minute?

[hybrid basin]

2,5 Minutes

[gentle cipher]

wow

[hybrid basin]

It would be sad, if it had been 25 min, but I think it's relatively good for such a short exposure time

[hybrid basin]

The problem are the CAs. Because of them I already stepped down to f/2.5, but apparently it's not enough, but it's much better than in my last M31 pic.

[hallow tapir]

aim for little longer like 3-4 hours and the image should look really nice

[strange seal]

3-4 hours untracked is pointless

[gentle cipher]

2 hours max

[hallow tapir]

traked i mean

[strange seal]

this is #1019718599922946089

[hallow tapir]

yea

idk

[hybrid basin]

Yes I'm currently building a diy tracker (I still have to buy some things, but at least I've planed to build one)

[hallow tapir]

oh nice

what type like a barn tracker?

[hybrid basin]

No it's more complex (many 3d printed parts), but it's only about twice as expensive as one (because I already have some things that are needed).

[sterile violet]

stock canon 2000d, 50mm STM lens

[midnight flower]

finally got your camera fixed?

the settings in it*

[sterile violet]

no?

my settings are fine

[midnight flower]

your images always look overly bright though

[radiant kestrel]

This is untracked??

[sterile violet]

yes sir

[radiant kestrel]

Dang

I don't think I've ever seen anyone resolve crescent untracked

[sterile violet]

i think its like my 3rd image ever or something

[radiant kestrel]

Have a feeling its all in the processing lmao

[sterile violet]

yep, 200 does wonders

[radiant kestrel]

Ah, pix?

[sterile violet]

i think

[radiant kestrel]

Gotcha

Well amazing job with it

One of the best untracked dsos I've seen

[midnight flower]

200 processing on my NAN prob gonna make me end up hating my images once they dont end at the same quality lol

[sterile violet]

thanks

[midnight flower]

here is what he did with mine somehow

he was the only one who was able to process it

me and zeg tried

[radiant kestrel]

Dang-

[midnight flower]

that was 17 minutes on a 55mm kit lens

untracked

[radiant kestrel]

Nice nice

I will hopefully shoot another 30m of data tonight
750x lights 61x darks 25x flats
2s exposures, 1600 iso

Amazing image!!!

[tidal tide]

darks with dslr 🗿

[sterile violet]

yes?

[tidal tide]

they arent worth it on dslrs, take bias instead

[sterile violet]

yes they are

[tidal tide]

what'd they help with, the thermal noise isnt consistent enough on dslrs for it to be of any use

[sterile violet]

noise

there is noise in any image

[tidal tide]

did you take bias?

[sterile violet]

no

[tidal tide]

theres the problem

[sterile violet]

darks still help

[tidal tide]

not really, just take bias and life will be easier, bias frames will remove the fixed noise and make it much better

[grave rapids]

Concordavirus is right here, bias frames are good

Actually I believe you can take bias frames now if you want @sterile violet, restack and see if it helps

[sterile violet]

sure, what do i do

is it the same as flats but shortest exposure

anyway focus is different

[grave rapids]

Same ISO, lens cap, lowest exposure

[sterile violet]

but when i add more data tonight i will take some for last night and tonmight

[grave rapids]

No thats dark flats

[grave rapids]

That’s fine, I think bias frames are completely reusable

[sterile violet]

yeah, you can take them like every month

[grave rapids]

Those help me a lot

[radiant kestrel]

You must take bias to use with flats

Darks don't help much on dslr

[sterile violet]

yeah but

[crimson fractal]

They are literally he most helpful calibration frame for me

[crimson fractal]

I’m using some bias frames I took at the start of this year still

[sterile violet]

Does temp matter?

Can i take it inside

[crimson fractal]

Bias only needs to be same iso and fastest shutter speed so no

*yes u can take them inside

[crimson fractal]

30s subs on jupiter ?

[real furnace]

that's out of focus, isn't it?

[hallow vortex]

yeah why would you do suchg a long exposure...

@high sonnet

I swear you're supposed to do as fast as possible

to get more data, faster, better res

also is it in focus

💀

okay

for planetary

you have to have highest focal lenght

track subject ish

fast exposures

why are you deleting

@high sonnet

??

[high sonnet]

any tips then

[tidal tide]

whats your average sub temperature?

[crimson fractal]

from last night it was about 12-24 degrees

they wokred in the stack pretty well got no hot pixels

[sterile violet]

How’s my image

[grave rapids]

Good! I think you could stretch it more if you want

[high sonnet]

how do these look

[visual pumice]

really out of focus

[high sonnet]

Okay should I use a more zoned in lens

That one is cropped

[visual pumice]

you shoud get more in focus?
also looks really shakey

[high sonnet]

Probability cause I made the mistake of taking 30 seconds exposure

[hallow tapir]

only 2min of data, i did it for a test to see if my other lens had a giant ring in the middle but its turned out only my 24mm had it

suprising it looks better then my old 20min of data smc and lmc shot

[sterile violet]

My final image untracked 5 minute total exposure time 3 seconds exposures

[strange seal]

SCNR that

[paper mesa]

Hey guys! I am planning to build an Image Restorer AI for Astrophotography. An AI model that can help remove noise artifacts, Sharpen the image. Deblur the Image if there is some object that is Out of focus etc. I am very much interested in Astrophotography but don't have resources to capture images. If you all can help build a dataset which can then be used to train this AI image restorer it would be awesome. If such tool already exist for Astrophotography then do let me know. 😁

[strange seal]

talk to @unreal grail , he has the same idea

[dusty gull]

That is definitely an interesting project
I think some people already did something similar in #🧠-deep-learning-biscuits (an ai tool to denoise)

[strange seal]

blurXterminator and noiseXterminator are the commercial ones

[paper mesa]

I can't find this channel

[paper mesa]

oh okay thanks for letting me know. I'll these out

[dusty gull]

You must add the DIY role

[strange seal]

the bot is down though

[mental pecan]

I've got about 200 images of an out of focus Orion...would you want me to send you the data?

[hallow vortex]

the core looks kinda blown out

[sterile violet]

yeah but i couldnt save it so it is what it is

[hallow vortex]

You could 100% save it

have 2 layers

[sterile violet]

wat do you mean?

[hallow vortex]

one with core not blown out but no backgorund detail

[sterile violet]

when i streched it, the core was liek that

[hallow vortex]

and then a main one

Can you send the TIFF pls

[sterile violet]

how do i make that?

when i streched out the image the coree was like that

[hallow vortex]

search on youtube a tutorial for orion, I'll send it

[sterile violet]

sure

[hallow vortex]

https://www.youtube.com/watch?v=bDqrW8cLEx8&t=1512s&ab_channel=TheHeavensDeclare

send the raw file tho pls

[hallow vortex]

ty

[sterile violet]

i combine the stacked with the final image?

the streched image has the orion blown out

[hallow vortex]

Just look at the video

[sterile violet]

yes, but he uses the streched one

[hallow vortex]

yeah

he has 2 stretched

[sterile violet]

wait i have an idea

ill strech it a tiny bit and erase

[hallow vortex]

@crimson fractal Could you have a go at this data too, I think it has some good potential

[sterile violet]

@hallow vortex i cant do the same crop

the final image is cropped down

[hallow vortex]

what

[sterile violet]

nvm

[paper mesa]

Yeah please, do share the data with me

[sterile violet]

but how do i add the image to the same layer

[hallow vortex]

wdym how do you do add the image to the layer

bro

look i'll send a pic rn

[sterile violet]

move that image underneeth that layer

because its in a different tab

[hallow vortex]

you see

[sterile violet]

i use siril

[hallow vortex]

copy layer paste layer

[hallow vortex]

can't you use Ps

[sterile violet]

no

[hallow vortex]

It's teh same thing

[sterile violet]

no

[hallow vortex]

you're using photoshop aren't you

[sterile violet]

and siril

[hallow vortex]

in here

[hallow vortex]

isn't this Photoshop

[sterile violet]

backround extraction, colour calibration

[sterile violet]

yes but i use siril to stretch

[hallow vortex]

oh my

[sterile violet]

and backround extraction

[hallow vortex]

It doesn't matter what you use to stretch

[sterile violet]

but i need backround extraction and colour cali

[hallow vortex]

why do you need bg extraction

[sterile violet]

to fix the backround

the gradient

this part is too light

[hallow vortex]

Use camera raw filter

or gradient fixing shi

[sterile violet]

i use siril

100x easier

[hallow vortex]

@indigo dome could you have a go at this data, i think it has potential 100%

FFS

wrong tag

@sterile violet you're the 200 that did decent editing right, there's 2 200s and I can't remeber which one is which 😭

[sterile violet]

That's my alt

[hallow vortex]

ahhh

okay

okay

Could you try the data pls

it looks pretty decent

[sterile violet]

When I'm home

[sterile violet]

Sure

[hallow vortex]

yes yes ofc

ty

[sterile violet]

Np

[hallow vortex]

Imma try B3 f2 of orion 2 hours exposure in a week, maybe you could have a go at it when I get it, on the 22nd I'm travelling and hopefully I get some decent data

[sterile violet]

lets go

thanks

[sterile violet]

@hallow vortex bit better now

[hallow vortex]

still quite a lot of noise tbf

but yeah it's pretty good

[sterile violet]

ill try some reduction

@hallow vortex better?

[hallow vortex]

i'd say so ig

[sterile violet]

ill turn it down a bit

but yeah super happy with it

[hallow vortex]

for sure

what bortle was it

[sterile violet]

7

[hallow vortex]

that gives me hope for mine

[sterile violet]

gl

[hallow vortex]

Same setup basically but I'll use F2.5, and instead of 2S subs I'll use either 5 second subs

and 2 hours

[sterile violet]

untracked?

[hallow vortex]

yup

[sterile violet]

if so i wouldnt go over 1h 1/2

[hallow vortex]

oh and

B3

[hallow vortex]

why

[sterile violet]

data collection will drop off

[hallow vortex]

fair enough

[sterile violet]

i would go 1h 1/2 most

but it will help a tiny big ig

[hallow vortex]

Idk i'll get 2 hours worth of data and worst case I can just get the best 80% instead of all yk

[sterile violet]

yeah that is a reason to do it

you can stack less % of frames

[hallow vortex]

yeah exactly

[sterile violet]

so the image is better

[hallow vortex]

tho the atmosphere there has never been difficult to work with

[sterile violet]

but dont go over 2h there is no point

[hallow vortex]

yeah ofc

I'm not staying out for more than 2 hours for orion

What ISO did you use

[sterile violet]

1600

[hallow vortex]

oh

thats not very high at all

why not 6400 or even 3200

[sterile violet]

noise

depends on what camera you have anyway

[hallow vortex]

BUt with so many frames it would probably not even be noticable right??

at least with me

[sterile violet]

nah

if i use 3200 iso noise will be high

but depends on the camera

[hallow vortex]

yeah

[sterile violet]

some cameras are best at 800 so

[hallow vortex]

Idk i'll keep it at 3200 iso

It's what I've done for a while and noise isn't bad

[sterile violet]

could you send my image to my dm when you have done your magic?

[hallow vortex]

and then @sterile violet could you send it to mine when you got it

[sterile violet]

[sterile violet]

@hallow vortex

core is fixed

[hallow vortex]

Ayyy nice it looks really good

We'll wait for 200 as he is built different, you have an untracked sub and makes it into a JWST image

[sterile violet]

yes

[hybrid basin]

Knows anybody what I can shoot tonight? I have a 85 and a 300 mm lens and I'm not sure, if I should shoot M31 at 85mm, M33 at 300mm or the Pleiades at 300mm

Or es there a even better target?

I'm of course untracked and my cam can take about 300 subs until it needs 2 hours for charging

[sterile violet]

orion

[hybrid basin]

Its at 8 pm visible, so I would waste 2 hours of time, when I could already shoot

So I think its not a option

[sterile violet]

so? you going to get the same exposure anyway

if i shoot between 11-12 instead of 8-9 ill still get 1h of exposure on what i want

but its up to you on what to get

[hybrid basin]

The problem is, that my camera can only take 300 subs per battery and I only have one. If I take 300 2s subs at 85 mm (thats the lens I would use for orion) then I would have 10min. Then I have to hours for charging and then I can take another 300 subs.

[sterile violet]

ah you want to re chrage through out the night?

[hybrid basin]

If I want to take more than 15min then I have to

[sterile violet]

sorry i thought you where going to shoot a target and charge it in the morning or something

[sterile violet]

save for a dummy battery

[hybrid basin]

I never tried out my camera for AP before, but Nikon says that it's possible to shoot 300 pics. But I dont have to use the monitor, but it'll be very cold. Is it possible to shoot more pics in AP?

[sterile violet]

idk, my canon 2000d lasts around 2h 1/2

[hybrid basin]

For the Nikon Z50 is nothing but a Aliexpress dummy battery available

[sterile violet]

constantly shooting

none on amazon or something

you can plug it into a power bank and get lots of life

[hybrid basin]

I'm not sure if it is good to put a 20€ dummy battery in a 1000€ camera...

[sterile violet]

i mean that is the normal price for one

they arent battery's, just adapters to connect it to a power bank

[hybrid basin]

I found out, that there are some for 66€ on Amazon

[sterile violet]

bit expensive for a dummy battery

but sure whatever, make sure tou have a power bank to plug it into

but some powerbanks wont provide enough volts

you can also plug it into a mains

[hybrid basin]

I found one for 45€. Maybe thats a option, because its about as expensive as a normal battery, but I really need a dummy

[sterile violet]

does it plug into mains?

[hybrid basin]

What are mains? 😅

[sterile violet]

a plug

like what you plug, plugs into

your house power

[hybrid basin]

Then yes

[sterile violet]

make sure not to over power it

but yeah, if there is a plug nearby the battery will last forever

well you know what i mean

[hybrid basin]

But I also fund one for 60€ that can be used with powerbank. Maybe thats a option, because I can still use it with plug then

[sterile violet]

up to you

but you need the right power bank wich can provide enough energy

@west heath how much volts do you need again for a camera?

[hybrid basin]

Ok thanks. I think I'm going to buy one (usable with powerbank and plug)

[hybrid basin]

8.4 volts

[sterile violet]

i dont know if normal powerbanks have enough energy to keep it on

[sterile violet]

yeah get the right one

and a powerbank that can last a long time

[hybrid basin]

I think the best way is to check, if the dummy battery really deliveries the right voltage is to measure it first. Just for safety

[sterile violet]

yeah

[hybrid basin]

Hasn't the powerbank just to support fast charging to deliver 9 Volts?

[sterile violet]

powerbank should say how many volts it has

like mine says it has 5V

[hybrid basin]

Yes they normally have 5V, but some already support fastcharging. Fastcharging delivers 9 Volts (as far as I know), but I dont think its in that topic anymore

I'll ask in Should I buy this, if anyone has already tried a dummy battery for the Z50, because I dont want to destroy my camera

[west heath]

Depends on the type of fastcharging

Just get a dummy battery with a step up converter @sterile violet

[sterile violet]

oh ok

[hybrid basin]

Small update: I already took 700 subs of the Pleiades and the battery still lost no bar. Probably the display is an important factor

[hybrid basin]

It lost one bar after 1000 subs

[sterile violet]

Yeah, turn it of

I can go for alot longer than conon says

[hybrid basin]

I got more than 2000 pics, so 30min of exposure time. I'm currently stacking it

[hybrid basin]

Heres the result. It isn't as good as I expected. I should've taken the pics of Orion, but the Pleiades are just to difficult for untracked without collecting and processing days of data 😅 .

30min exposure time

[little prism]

better than mine

[sterile violet]

30m? damn

i managed to pull way more out with 25m

[hybrid basin]

I was at f/3.5

[sterile violet]

i was at f/3.2

so very similar with completely different results

even at 15m i could get more nebula (noise was bad)

might be the lens though

[little prism]

I was inexperienced as fck and managed to do everything wrong that is possible to go wrong... I did way to long exposures... I used a way to low ISO and there where slight clouds which ruined everything. Let's just say that the 44 min of data I collected where pointless and not usable

so be happy with yours. It looks great!

[hybrid basin]

My image isn't so good processed, but I dont think theres so much more. Heres what it looks like in histiogram in Siril

[sterile violet]

give me data

[little prism]

give him data

[hybrid basin]

Ok thanks, should I send it here or how can I do it?

[sterile violet]

send it here

[little prism]

share it with your google drive

[sterile violet]

if the file is too big then google drive

but if its small enough sent it here

[hybrid basin]

it is

[sterile violet]

go to google drive and send the link to it

upload to google drive, right click on it, get link, anyone with the link, then copy it

then send it here 😄

[midnight flower]

there, I made it look normal

[grave rapids]

That looks fine

[sterile violet]

thats png though

[grave rapids]

Histogram stretch always looks crazy

[sterile violet]

yeah it shows where all the data is

[midnight flower]

I took his over stretched image and put it in gimp

thats not his actual data

[sterile violet]

yeah but you got the png version of it

or the compressed one

[midnight flower]

it was compressed in the first place

[sterile violet]

details wont be as good

[sterile violet]

yeah, to send it on discord

he is gonna send the tiff file

[little prism]

basically like opening up a raw file on your pc or smth. it looks really bright and there is lots of noise. It just shows you what your raw data really looks like xD

[hybrid basin]

Yes I currently try to upload it

[sterile violet]

yeah

[sterile violet]

take your time

[midnight flower]

this is best I could get with that over exposed image you showed us

its all there though

[hybrid basin]

Ok thanks It looks better than my processing

Its a screenshot

Heres the link

https://drive.google.com/file/d/1pAxoaLsGb0lYKvXPxA2IYSQqMf3GkAtS/view?usp=sharing

[little prism]

@sterile violet Do your job!

[midnight flower]

you need to make share public

[sterile violet]

ill try

[sterile violet]

you need to make it so anyone with the link

[hybrid basin]

Thanks. Übung macht den Meister... I used a much to high ISO at my first images

[sterile violet]

alright send the link again when your donwe

[midnight flower]

after color correction, and stuff this is what you got

[sterile violet]

but you are editing compressed file

it wont be as good

[hybrid basin]

Oh no and now my internet is very slow because I use mobile data, because my WLAN is blocked after 0 am. But I'll try to make it public

[sterile violet]

try your best

[midnight flower]

its going to be hard to pull out this much gas detail, the only reason there is so much is because it got over stretched to crap, and I know how to fix it

[sterile violet]

yes but streching a compressed file will make quality worse

[midnight flower]

i never stretched it though did I

[sterile violet]

yes but doing anything will make quality go down

its compressed, if you use raw image quality is better

[midnight flower]

ok pull that much out of your edit then

[hybrid basin]

It should be public now

[sterile violet]

ok thanks

[midnight flower]

that aint his data

[sterile violet]

yes i cant use his because its compressed

[hybrid basin]

Oh it still isnt

[midnight flower]

its not

[sterile violet]

the link is not public yet

[midnight flower]

I just used his compressed image, when he sends it in discord it's gonna be compressed anyways

[sterile violet]

not with google drive

[midnight flower]

I dont see why you're so upset about me showing him what he actually got

[sterile violet]

it will be the full raw image, so detail will be better

[midnight flower]

no shit I never argued that point

[sterile violet]

im not, you can get higher quality with raw

thats all im saying

[hallow tapir]

hi

pleiades

[sterile violet]

yes

[hybrid basin]

I know a way to get around the blocking of my wlan, but I'll need probably 15min

[midnight flower]

I was talking ab when he posts it in deep space pics and stuff

its gonna be auto compressed

[sterile violet]

but if you screenshot the raw quality will technically be better than double screenshoting a compressed

[midnight flower]

I didn't double screenshot it, I downloaded the image he sent

[sterile violet]

yes, downlaod one compressed image, screenshot and compress it further

[midnight flower]

download one compressed image, put it in GIMP, edit it, then download the edited version off GIMP

there is no double compression

[sterile violet]

arnt you compressing the file when you export it?

[midnight flower]

no it is already a png, so there is no need to compress it further

I downloaded the original image as a png, and exported it as a png

[sterile violet]

fair

but i mean when you edit the compressed image, the quality decreases so

but yeah whatever

[midnight flower]

im not telling him to use it as a image he took, I am just showing him what data was in that over stretched screenshot he sent that looked like god staring into me

a auto stretch probably wont be able to pull out that much dust, but it will also be less noisy

[sterile violet]

yeah, but you did say that was the one he should put in #deep_space_pics

unless im reading it the wrong way

[midnight flower]

i never said that

at all

I dont get how you got that out of what I said

[sterile violet]

its in the screenshot

im probably misinterpreting it

[midnight flower]

I was talking about the raw data

when its put in discord

it is automatically compressed

into a png

[sterile violet]

oh

guess we both didnt understand each other

[midnight flower]

most likely its going to be very hard to get that amount of dust out of the image off a basic auto stretch, since he stretched it to the max, and i got rid of the noise, and flattened the background

a really big stretch will bring out faint objects, but it also degrades the image by a lot, and makes it more grainy, noisy, and bright

[hybrid basin]

I set it now to public

Now I'm sure

[midnight flower]

alright let me try it

its public now

[sterile violet]

thanks

[grave rapids]

DBE fixes it, I’ve had the same thing

[hybrid basin]

Yes I cropped it very much

[unreal grail]

When you dither too much

[sterile violet]

solved ig

[midnight flower]

yeah if I process this image the result is gonna be similar to what I got from that stretched out one

[hybrid basin]

Yes I think the histiogram view shows already all details, that can be possibly made visible

[sterile violet]

yes it does

this is very hard data lmao

[grave rapids]

But it can be improved a lot from the histogram image

[hybrid basin]

Yes I dont think it's so wise to put a lot of work in that image. But the parts for my tracker will be delivered in January. Then I can try the Pleiades again, but untracked they're very hard.

Until then I'll try Orion or something like that
