Re-edit of a shot from last summer, with background removal tool I’ve been working on for AstroShader.
iPhone13 and tripod: 150x 4s, ISO 1600

30mins at 135mm

[fervent lintel]

25-28 min exposure, each frame 3.2 seconds i think, taken with Canon 600d and Samyang 85mm f/1.4 (and basic tripod ofc)

[paper arrow]

oh snap

ive got a 650d

and untracked

[fervent lintel]

Niice

Wait

Ive never heard of that dslr before, lemme check

[paper arrow]

its slightly better than the 600d

flip out screen and some other features

[fervent lintel]

Cool, i think my 1d mark ii is better than 600d but 85mm is not enough magnification, and objects look smaller

[tame panther]

oh yea I usually do, but I put no effort at all into this image so I didn't bother this time

[compact pagoda]

with untracked shots do you have to keep bringing the target into center of the shot after a few mins?

[urban ginkgo]

Is this picture good for 40 min exposure with class 5 bortle? 50 mm lens with canon 1300d and no tracker

[tame panther]

yeah, I usually reframe and dither after 50 frames

[tame panther]

yeah that looks pretty decent, there might be even more data you could pull out

One question for all of you untracked enjoyers, how do I dither an untracked image?

Do I have to move the tripod slightly every few shots?

I also reprocessed this one a time ago. Let me know what could I improve for the next time!

[urban dirge]

1300 frames of the pleiadis 1.3 sec iso 4000 f5.6

[sharp ruin]

Out of curiosity what's the aperture of your scope? It seems like it always takes a relatively long time to resolve nebulosity in the Pleiades, and with only thirty minutes you've already got some here

[urban dirge]

i shot this at 240mm

[sharp ruin]

Ah ok, not bad actually

[urban dirge]

this is an image i took with only 130 1.3 sec frames

[sharp ruin]

Woaaah ok

That's really good

[urban dirge]

i didnt edit it tho

[paper arrow]

Don't move the tripod but rather the mounting (left right and up down movements) instead

Make it a slight movement, no5hing dramatically

[native juniper]

Ah ok, I'll try it next time

my walking noise was awful

thanks!

[tribal jetty]

Average of 0.3 seconds on the exposure

whats your setup?

[tribal jetty]

[granite hemlock]

Ahh i got a 8" dob skywacther 200p with a neptune 664c cam

how did you image the whole orion ?

by peacing parts together?

[tribal jetty]

Nice, ya PO makes some good cameras! this is just a stack of a bunch of single images. I just manually select the ones closer to the middle of the frame for stacking so it gets the best field of view.

[granite hemlock]

wow that is a great shot

[tribal jetty]

Thank you!

[wintry mountain]

how can U get so pinpoint stars with untracked???

damn dude

[paper arrow]

Short exposures

These were 2 second subs

2275 of them in fact

[paper arrow]

And I'm still getting more

Next new moon, I'm shooting this at f2.8

Maybe get another hour????

[granite hemlock]

anyone know why i cant get focus ? im using a neptune 664c with 200p dob untracked , looking at the moon and its just picking up a white blur.

[dusty gull]

Looks like the moon is way overexposed

The moon is really bright, a few milliseconds with low gain is enough most of the time

[granite hemlock]

yeah i fixed it now thanks alolt , any reccomendations for trying to see nebula ? i wanted to try orion but idk what exposure is good enough

[dusty gull]

I presume you're around f5 in which case 200ms is about enough to see the core of orion. With 500ms and extreme histogram stretch I can spot all major objects, ngc 891 is the visibility limit

Gain about 5/6 of your cameras max gain

And for imaging, set your exposure as high as possible while still getting round stars

[granite hemlock]

alright thanks alot

[compact pagoda]

as high as you can get without trailing right?

[dusty gull]

Yep

Untracked is already hard enough, you don't want to deal with even higher noise and fewer stars/subframe

[paper arrow]

untracked is easy when youve got lots of data to play with

and a fast lens

[robust sonnet]

did u take calibration frames?

also it looks rlly good

[spice ingot]

What iso should I use for my untracked subs? I’ve been using 6400 and i think it’s decreasing the dynamic range too much. Should I lower it?

[tame panther]

what aperature are you shooting at? i shoot at 50mm f/1.8, so i typically shoot at iso 1600 or 800.

[dark token]

800 here, although i guess i could maybe go to 100

[paper arrow]

i use 3200 or 6400

1600 for milkyway

[paper arrow]

ive got 106 completed images

these are the ebst ones ive gotton

might do some tweaking to the lmc photo

[paper arrow]

Huh

Who made you the iso police

I've used iso 12800 before

All my star clusters are shot at iso 12800

Since I can sacrifice dynamic range for a brighter image

No this is the Wishing Well Cluster

No.

I will have a legacy of being untracked

I've planned some ambitious projects

Yea but that's boring

Skill issue

[compact pagoda]

is untracked on a dslr easier than untracked telescope?

[ornate spade]

yes, lower focal length(aka with a camera lens) untracked is much easier since you get to use a much longer exposure time, if you double your exposure time per sub you will have 41% more signal in the same amount of time stacked.

[ornate spade]

https://docs.google.com/spreadsheets/d/1tSEbji6V4rYz81COybiD5LWaekULIQReJy7kZCxQy78/edit?usp=sharing Have a look at this untracked calculator to calculate exposure times.

[paper arrow]

by far

[compact pagoda]

Yea I’ve used this before and it gave me something like 0.200ms

What do you guys do to protect against wind ruining ur shots

[paper arrow]

not shooting when theres wind

get a light box

or one of those massive boxes people get for moving stuff house to house and cover your setup with it

[compact pagoda]

Oooo that’s a good idea

[spice ingot]

(Could the lines be caused by the clouds? There were clouds in the picture/Also why didnt siril pick m33 in photometric callibration, saying it cant align the stars with reference)

[paper arrow]

siril is pretty wack when platesolving

[violet warren]

I'm still trying to get my tracker to listen to me, so I do most of my stuff untracked. I have one question. If I decrease my exposure time and increase my iso, will I get sharper and less traily results? or will it be just noise (iso from 1600 and 3200 to 6400 or potentially 12800)

[paper arrow]

increasing your iso just makes it brighter while reducing noise but also loosing dynamic range

reducing your sub exposure time will help

as per "sharper" images, not really

[tidal tide]

the loss of dynamic range when doing untracked doesnt matter whatsoever

[paper arrow]

still, you are loosing it

[tidal tide]

once he gets a tracker then he will have to take it into account a bit more

[violet warren]

so, just decrease shutter speed?

[paper arrow]

yes

[tidal tide]

Your stars are lines, yes

[violet warren]

well is there a way to get sharper photos then?

[paper arrow]

what do you mean "sharper"?

[violet warren]

yes I know, sorry for the monstrosity

well just not as blurry

[tidal tide]

tracking

[paper arrow]

more intergration and dont do heavy denoising

[paper arrow]

while this can help, its not absolutely nessesary

[violet warren]

I know bruv 😭

[tidal tide]

wdym not absolutely necessary

[paper arrow]

my images are decently sharp

[tidal tide]

with no snr

[violet warren]

yup, sounds good enough

okay you two stop and let's spread love

not hate eachothers works

[ornate spade]

The lines are walking noise(you need to move where the camera is pointing every few shots(couple of mins at least) to reduce it).

Siril's PCC is a bit weird it expects the coordinates you provide to be the exact center of the image, as M33 is to the side it won't work. Try platesolving it(either set it up in siril, or use astrometry/ask a bot to get the coordinates from there).

[sharp jungle]

Guys, what focal reducer could work great with a 12” 1500fl dob and an imx224, the views are way to close and it’s hard to image untracked so I need a bigger fov, but a new camera would be too expensive, I was thinking about some kind of 0.5 reducer, any suggestions?

[dry spade]

That would make it f/2.5. You’ll probably get serious distortions around the edge and some vignetting, but with a small sensor like the 224 you might miss the worst of it? Hard to tell.

[sharp jungle]

Can’t I just crop the edges?

[dry spade]

Yes if it’s just around the outer edges. Alternatively you may be able to find a used DSLR for the same cost as a reducer, though DSLRs are not great untracked.

trying to stack my 750 frames of Cygnus I got last night, siril keeps getting to the rejection stacking part and then freezing

im gonna give it a while and hope it works

[tame panther]

it just finished stacking, and im very happy with how the data looks thus far

not too much gradient, the stars look great, and noise isn't too bad

very little aberration as well

if i process it right, this may end up being my best image yet

when im done ill also post it in #1021002743080558642

think im gonna put the data through startools instead and see if i can get anything there

[mild smelt]

Can someone help me

I have a dob and even if I do 1 second exposure I get star trail

[ornate spade]

That is to be expected unfortunately, if it's not due to vibrating the scope after touching it your max exposure time is probably lower than 1s. Not entirely sure how to calculate it properly with a phone+eyepiece combination.

[mild smelt]

I will buy a Dslr I will get exactly the same star trail?

[ornate spade]

You can cheat and just 2x2 bin to double your max exposure time at the cost of resolution, which would be the best option. Also if you are using a phone holder I don't think its centered properly. Could try stacking a bunch of raw pictures once you find the max exposure time, just won't be very efficient.

[ornate spade]

With the scope yes. DSLR+Dobsonian is not a very good idea. Much better to get some astrocamera, much more sensitive and much easier to get a lot of photos at the cost of having a smaller sensor size and fov which is a pain.

DSLR+camera lens is pretty damn good, and is much easier than with a telescope.

[mild smelt]

I want to put it Into the telecope

[ornate spade]

https://docs.google.com/spreadsheets/d/1tSEbji6V4rYz81COybiD5LWaekULIQReJy7kZCxQy78/edit?usp=sharing
Check the untracked calculator for an exact amount with a dslr/astrocam and your scope.

[ornate spade]

Well you could do it, but you'd only be able to barely get the brightest objects. You get much more light per pixel with a camera lens, due to longer exposures and the objects being smaller in the picture.

[mild smelt]

I dont have the money to buy a camera lene and a mount

[ornate spade]

You don't need a mount with a DSLR, some cheap camera lens that comes with the scope(or something like a cheap canon 50mm f1.8) can work.
If you want some tracking with it, you could make a cheap barndoor hinge tracker.

How so? It's possible to get nice photos with an untracked setup, certainly cheaper than getting an EQ6 mount that's for sure

[paper arrow]

its better to have the eq6

[sharp ruin]

For sure, untracked can be sufficient though

[sharp plume]

I did untracked for 3 years. Tough times 💀

Currently, I would have made a tracker if I hadn't found my equatorial mount for such a low price... I plan to make one by the end of the year that's more portable so I can use it away from a outlet. I'll build it using only belts, making it cheap and sufficient for widefield photography.

strain wave mounts shorten exposure on your guiding so you'll have harder time guiding

you might also consider the eqm-35 pro as an alternative to gti with larger max load

i mean they are really simmilar

honestly both work really good for reasonably small scopes

if you decide to choose them, pick whichever you get the best deal for

[paper arrow]

No. He isn't even in this server

[paper arrow]

No.

[wispy fractal]

Aww

[earnest quarry]

i have a younger brother

[paper arrow]

good job

[earnest quarry]

taken with untracked 6"dob and phone

[gentle birch]

niceeee

[earnest quarry]

new and better process

[inner crystal]

How did you process this?
Looks great!

[earnest quarry]

yes i did

[earnest quarry]

u have made an inccredible app

[inner crystal]

BlurXterminator?

[earnest quarry]

yeah

[earnest quarry]

that isnt cheating right?

[inner crystal]

It’s winning 😎

[earnest quarry]

[west thorn]

You’ve improved so much!

[earnest quarry]

[paper arrow]

good job

[paper arrow]

44mins on LMC
70mm
f/2.8
iso 1600

This is my last untracked project.

[bitter dove]

You getting a star tracker?

[paper arrow]

yes

[bitter dove]

Nice!

Which one?

[paper arrow]

modded HEQ5 or a swsa

[bitter dove]

Really wish I could see this in person. Love the details though!

[bitter dove]

You probably only need the swsa for a 70mm. Unless you plan to use it for a larger scope

[paper arrow]

am aware

[paper arrow]

Alright guys, tommorow im getting a mount

its been a long time.

[tidal tide]

salute2

[robust sonnet]

🫡

Enjoy the tracker

[compact pagoda]

what mount?

[paper arrow]

HEQ5

[bitter dove]

O7

[paper arrow]

farewell everyone. its been great serving this place for the past 2 years. my legacy will live on

[ebon hedge]

Finally

For the love of god

[paper arrow]

I've had it for a week lol

[paper arrow]

i should prolly take a better image

[paper arrow]

better imagr

[marble kite]

that cam is NOT fit for that mount.
We should trade, I have a swsa gti. its much better

[paper arrow]

[late bear]

first time trying astrophotography didnt take nearly enough darks so the histogram is really skewed and i had to try to remove the red background but we got there kinda

[ebon hedge]

Let sword cook

[marble kite]

No he should def trade with me

[ebon hedge]

No ur just trying to get an heg5 for practically free

[marble kite]

No im making sure he has fun in this hobby

[tidal tide]

hes been through enough with like 2 years of untracked, he'll be fine

[ebon hedge]

he has a totem of untracking

[paper arrow]

Pay for the shipping

[marble kite]

I pay for my shipping you for yours

[errant lichen]

Orion was my first untrack deep sky object ive captured

Second was carina nebula

[dark token]

what exposure time and equipment?

[errant lichen]

Canon 1300D tamron lens 70-300mm
First pic was 1s x 1790
Second carina nebula 1s x 300 images

30 minutes orion and 5 minutes carina nebula

Stacks at siril, graxpert for denoising, starnet for stars removal, photoshop for stretching and finishing

And it was captured at bortle 9

[normal elk]

Bruh overkill

Technically this is untracked because its at 1s at 600mm focal lenght

14m total intergration

Also dont mind the coma and color fringing my coma corrector is not at the right backfocus

[errant lichen]

How it didnt trailing tho

[normal elk]

Thats cause it is tracked but its with out polar alignment so most i can do is 1s to 5s but 5s has some visible trail

And the reason for no polar alignment was its behind a wall

And i wasn't bothered to do it electronically because my setup isnt complete yet

[orchid obsidian]

I am still experimenting with my Nikon D200 I also have a Celestron Travel 80 and have just got a T ring adaptor and extension and a 2xBarlow to see if I can use the 400mm F5 celestron to get something usable in Orion. Of course I need to be able to see the sky first! Any advice of exposure times ISO etc. Calculators suggest .5 sec I have had no luck so far with the kit lens images are super grainy even with 5+sec exposures proabably because I have no idea what I am doing.

I know the kit is not the best for AP but it is what I have to try and learn the basics.

I have the tech side sorted. I have a dedicated Astroberrry server on the tripod and can control the camera remotely with EKOS. There is no live view on teh D200 and focusing is a PITA. I have a solid photography tripod though so that should help.

At 400mm F5 the frame will be pretty zoomed in. The Nikon has pretty big pixels also. If I get some sensible shots I will post on here to see if anyone can help with the processing. anyway wish me luck.

[outer sedge]

#1034944406622584872 message @paper arrow
this is insane ! How do you do untracked for 3 hours of exposure? I stand outside for 2 hours and somehow only get like 20 minutes.

[paper arrow]

Several nights of imaging

It's Certainly a grind

[errant lichen]

What do you use to stack?

Im planning also to do 3 hours of carina nebula untracked

Must be 10k frames out there xD

[paper arrow]

Good Luck. It's gonna make you insane

For my Carina project I Stacked in pixinsught but generally I use siril

[paper arrow]

This is all the raws and calibration frames
Stacking was more than 3tb

5180x2s was my intergration

[errant lichen]

Nahhhh

3tb is insane

Im still collecting

Had only 23 mins

[paper arrow]

by the time you get to 1hr and half, youll start going insane bc it gets fucken boring to image the same target over and over again

[errant lichen]

Im ok with that boringness (maybe)

But my pc 💀💀

[paper arrow]

is this your first 3hr project

[errant lichen]

Yessss

Long project

[paper arrow]

yea youll defo get that feeling

i spent 8 nights on my carina project

and that was over 3 weeks

[errant lichen]

8 nights for 3 hours its kinda fast

Mine 4 nights but only get 23 mins

[paper arrow]

oh my

what focal length you shooting at

[errant lichen]

300mm

1s shutter speed

[paper arrow]

ah thats why

i did at 200

[errant lichen]

Yessir

[errant lichen]

Full frame?

Or apsc?

[paper arrow]

aps-c

[errant lichen]

2 second...

Wouldnt that be trailing?

I use canon 1300d stock tho

[paper arrow]

i was also stock dslr

[errant lichen]

Maybe little trailing its okay?

[paper arrow]

it was able to stack fine

2tenths of a second at 200mm isnt much

[errant lichen]

Yeahhh i guess soo

[paper arrow]

ill show you my stars

[errant lichen]

Kkk

[paper arrow]

no blurx or any decon

this is 1:1

raw stack

[errant lichen]

It looks fine thoo

Jeez nice maybe the camera itself has a good image stabilization

[paper arrow]

i believe i did have it on for my lens

i used 2 lenses for this project

one of the lenses i had to turn IS off bc it made my stars deliberatly trail

[errant lichen]

Aaaaa i see

Very good thoo and it has slightly chromatic

[paper arrow]

also carina region is CRAZY star dense

[errant lichen]

Yeahhhh

I have 300mm but it has worst image stabilization

[paper arrow]

aare you using the 75-300mm lens?

[errant lichen]

Yesss

[paper arrow]

f/6.3 is gonna screw you over

🐌

[errant lichen]

5.6 actually

[paper arrow]

oh not as bad

i was at f/2.8 and 5.6

[errant lichen]

Wowww

Ofc 2.8 its better

[paper arrow]

i originally wanted to start and finsih this project with the 200mm lens but i got 3 clear skies earlier than i expected so i started it with my 55-250mm kit

[errant lichen]

Not badd thooo

It looks very good on 200mm especially 3 hours of int time 💀💀

[paper arrow]

yea defo

just a lil bit annoyed i didnt spend more time properly working on my final image

[errant lichen]

Man that part is the most fun

[paper arrow]

while this image is pretty good, when pixel peeping its got some issues and once you notice them, it ruins the image

reprocessed the data a few days ago and got this

[errant lichen]

Damnnn

Looks very sharp

I had to use graxpert

Due to my lack.of int time

[paper arrow]

i was using deepsnr

[errant lichen]

That can remove the noise.also?

[paper arrow]

yes

its pixinsight only

[errant lichen]

Aaa

[paper arrow]

deepsnr is a denoiser

[errant lichen]

I always curious for the pixinsight

Is it any good?

It can stack also right

But using less storage

[paper arrow]

pix is amazing

[paper arrow]

ehhhh not nessesarily

[errant lichen]

Then im cooked 💀

[paper arrow]

buy an ssd

[errant lichen]

Already had

But only 512

[paper arrow]

ah

[errant lichen]

Maybe ill do batch stacking

Ill do 300 frame stack

And stacks the multiple 300 frame stack

[paper arrow]

yea do that

[errant lichen]

Or maybe using sequator

[paper arrow]

absolutely do not use sequator at all

[errant lichen]

No need to use storage file

[errant lichen]

Wait what

💀

Its bad?

[paper arrow]

its the worst stacking software for dso

its horrible

at least stack in siril

[errant lichen]

Alright maybe ill do stacking the stacks

[paper arrow]

i had to stack each nights data on their own and then combine them

[errant lichen]

Ohhh stacking the stacks

Niceee onee

Yeah i need to do that

[paper arrow]

Yea well how else are you going to get 3 hours integration?

[errant lichen]

You mean the other object?

[paper arrow]

Huh

[errant lichen]

Im trying to get andromeda also

At 135mm focal length

[paper arrow]

Alright

Another 3 hour project?

[errant lichen]

Yes after carina

If possible

Or if not andromeda ill try rossete

[paper arrow]

Wow.

I would not bother rosette untracked

Don't do it untracked. Waste of time and effort

[errant lichen]

I saw someone do it untracked

Hmm idk if its work

[paper arrow]

They did at f2

You're at f5

The light gathering difference is massive

[errant lichen]

Hmmm

Alright lemme try other one

[paper arrow]

There's not much good 3 hour untracked targets in the NH

Southern hemisphere has a lot

[errant lichen]

I live in sh

Equator actually

[paper arrow]

Oh

[errant lichen]

I did lmc

[paper arrow]

Do the magellenic clouds

[errant lichen]

But it kinda worse

The gradient 💀💀

I live in b9 and with worse pollution

[paper arrow]

I wouldn't have high expectations with your image then

[paper arrow]

@errant lichen how's it going

[errant lichen]

It keeps raining these days

I cant take a pic

[errant lichen]

Im good, but kinda stressed haha

[paper arrow]

I'll give you a very important note

[errant lichen]

Cant even take a single dso

[paper arrow]

DONT image your target after it crosses the meridian

[errant lichen]

Wait what why

[paper arrow]

It's gonna massively ruin your framing and you'll get more stacking artefacts

[errant lichen]

No wonder, i have like weird framing when im stacking my carina nebula

Cuz my carina were shots before meridian, and shots after meridian also, so when i do the stack, well, it kinda have a weird framing in there

Thanks thoo

[paper arrow]

Keep the meridian in mind for future projects

[errant lichen]

Yessir

Ill do it

[paper arrow]

also i hope you arent getting meridian and zenith confused. very different terms

[errant lichen]

Wait i forgot

Whats zenith

[paper arrow]

Darkest place in the sky. Directly above you

[errant lichen]

Oohhh

It's pretty hard to get a pic from zenith...

Alright today is clear i might be continuing Orion constellation

[paper valley]

Orion untracked, 45mm f6.3 about 10~ mins of data, processed by tohuastro (i believe that was his old name)

taken on 26 november 2022 so it’s quite old 😂

[errant lichen]

Thats so niceee

[sharp ruin]

That's pretty good for only a 45mm aperture, got a decent amount of Barnard's Loop nebulosity in there

[tidal tide]

tohu

[paper arrow]

wanted to mention but decided to leave it

[sly acorn]

Uhm 💀

[iron cloak]

Any tips on doing untracked astrophotography?

I can't afford a tracker so I want to know how to get good photos like the ones in here

[paper arrow]

Good luck.

[dusty gull]

What's your lens and camera?

[iron cloak]

A Nikon D3300 with the lens that came with it, a 18-55mm lens

[dusty gull]

Yeah good luck

You can get some cool results don't panick, but you'll need a lot of patience and frames

[errant lichen]

pleiades untracked

15 min integration only

ik its still had alot of noise

gotta expand the exposure time

[whole wasp]

Have you done this while it was cloudy?

[errant lichen]

Like the other dso?

[whole wasp]

This one

[errant lichen]

Yea, its foggy

[whole wasp]

Ok

Thought so

Don't do that

[errant lichen]

I thought it was gonna clear, so i force to take it, when i stack it, well it shows like that

[whole wasp]

Bruh

[errant lichen]

Well nevermind, at least it shows the nebulae

[whole wasp]

More or less

Wait until its clear. I expect great results

[errant lichen]

Yeahhh, idk about yesterday weather cuz the 100 frame sample it was good

So i left my camera with intervalometer

When i try stack it, it shows foggy weather haha, but its alright, had to retake again xD

[paper arrow]

Don't do that in your 3hrs of caring project

[errant lichen]

Lmaooo yeahh ofc no

[viral rivet]

hi

[errant lichen]

i decide to retake orion agaian total subs are 11 mins ill be adding again soon

[sharp ruin]

why does it look airbrushed

[paper arrow]

Watercolour denoising

[sand cipher]

its not roast my image tread

[errant lichen]

Prob graxpert

[chilly apex]

Why does it look like someone took a bite out of it?

[errant lichen]

No idea

It came out like that

You guys want to try process it?

Might be better if you guys process it

[viral rivet]

yeah sure

[chilly apex]

I'd be honored.

[chilly apex]

Please post it in #1021002743080558642

[errant lichen]

Okay, wait im still in college

[sharp ruin]

that darker region of the Orion Nebula is natural, to be fair. But this image does kind of accentuate it a little drastically.

it's not even like, a dark nebula region or anything. It's just less illuminated than everything else around it for some reason.

and if you have just enough integration time to get the outer fringes and the inner region, but not enough to resolve detail in that one part, it can look the same color as background space, and appear strange.

[errant lichen]

had already posted

you guys can process it

idk about this

this only strech in siril without processing in photoshop

[paper arrow]

theres not a ton of data to play with so ive not stretched it much

[errant lichen]

yeah only 11 mins

thats why ill be adding again

i wanna push my data over the limit

idk thats a good one or no

[paper arrow]

massive stacking artifacts as well

what happened

[errant lichen]

i dont mind with the artifacts since my goal only the orion and the runningman i can crop it

[errant lichen]

well i shot with 2 variant angle lmaoo

since its blocked by building so i have to tilt my tripod to the fence so i can get the nebula

that happened haha lmao

[lusty mantle]

all of these were made with my canon T3i

[errant lichen]

that looks great

for untracked one

[lusty mantle]

[lusty mantle]

i have one with the telescope but i want to make more subs

[errant lichen]

im cooked

i got 1 hour data

honestly.... i dont see any difference 23 minutes or 1 hour man

[paper arrow]

Is that only your lights and calibration?

Are you full frame or APS-C

[errant lichen]

Apsc

Included with calibration frame

[paper arrow]

Wow.

Do you have a temp folder in there from stacking?

[errant lichen]

Yess

I spammed like 1500 photos last night

[errant lichen]

i could not tell the difference over here

left side is 23 minutes

right side is 52 minutes

this is my process

i dont know why i like my 23 minutes more lmao

but 23 minutes highlight are clipped

[errant lichen]

but i think this is way more natural???

how do you guys think

this might be better

were able to pull out the dust

[lusty mantle]

1.44 tb

it's almost 3 times more space than what my hd has

[lusty mantle]

i think that looks too much articial, idk if it came from the stacking or happened in the processing but, seems like a painting

[errant lichen]

I use graxpert tho..

[errant lichen]

Yeah i was wondering why its not really that sharp enough

Ive shared my data in processing and shared data

If you want to process it, suree

[lusty mantle]

ok

where it is?

[errant lichen]

https://discord.com/channels/794642864218439681/1340558510005551144

[errant lichen]

Here

[lusty mantle]

i can't edit because photoshop doesn't accept gimp files

[errant lichen]

I wonder why im getting a weird background

And yeah after stacking it shows a purple tint over it

I dont know whats happening

[paper arrow]

your data is ffine

[errant lichen]

Alright, but yeah i need to keep my data consistent, especially stacking artficats

But man, clear skies in here like once a month

[lusty mantle]

orion 15 frames of 0.5 SECONDS, making this image was a hell because my tripod was dying to hold the scope pointing so high in the sky

also i commit the mistake of forgetting the cls filter in the camera and not changing the quantity of photos when i finished the light frames, so i just took 2 dark frames instead of 10

also the focus could be slightly worse since i didn't remove the cls filter

[sly acorn]

I don’t think 0.5 sec subs would work for a CLS filter

[lusty mantle]

yes

i know

[errant lichen]

42 mins of my orion

[paper arrow]

what happened to the colours

[sharp ruin]

it's very flat

no dynamic range, something went wrong in post processing

[errant lichen]

._. Idk you guys can process it

I like to slide the tint to purpleish

Idk why stacking from siril makes my color flat idk why

You guys can process it?

[sharp ruin]

We would need the raw unprocessed stack

[errant lichen]

Alright

Ill send

In here

[errant lichen]

https://drive.google.com/file/d/1_n0-3hfZ6p7AyfBmy-H8BuKAuu8fCMZC/view?usp=sharing

[errant lichen]

and somehow pulls out the color

i did some reprocess

bit noisy but yeahh

how u guys think?

[sharp ruin]

Colors and dynamic range look better, stars are still really weird looking tbh

[dusty gull]

They look a lot like those i got from my first pictures of orion back then, with a sony mirrorless and a bad stock lens

So i think its partly material limitation

[errant lichen]

i use stars resynthesis in siril in order to make the stars round

cuz it shows a little bit trailing

heres before

i think its because the chromatic abbertion from my lens

i gotta start invest to good lens xD

but hey i think its a decent result

[sly acorn]

Much better.

[errant lichen]

thanks

[sly acorn]

Ur getting better dude

Just practice on others data too

[errant lichen]

any improvement should i do?

[sly acorn]

#1021002743080558642 u can get some here

[errant lichen]

yeah ill try

[sly acorn]

Can’t think of much but

It’s weirdly soft

What are u denoising in? Photoshop?

[errant lichen]

yeahh

[sly acorn]

Please switch to graxpert

[errant lichen]

but ill try not to heavily denoise it

save it to tiff files?

[sly acorn]

Someone else told u that too

[sly acorn]

Ye sure

It works with all common files

File types

[errant lichen]

i mean the final result?

[sly acorn]

Ye

To share here save as PNG

[errant lichen]

hmm lemme try

using graxpert

original file

still looks soft?

[paper arrow]

oh my

[errant lichen]

what

[sly acorn]

What the

How much data is this?

This noise amount cannot be real wtf

[errant lichen]

42 mins

[sly acorn]

Maybe photoshop was better somehow for ur data

☠️

[sly acorn]

Weird

This is extremely noisy

Like nothing I have seen before

What ISO did u use?

[errant lichen]

6400

using darks and flats

[sly acorn]

Might be a bit too high.

Also flats dont work properly without biases

Take em

[errant lichen]

and biases also

calibration frame were taken

[sly acorn]

Ah

There’s a website to know the ideal iso but

[errant lichen]

well actually

[sly acorn]

6400 is definetly too high

[errant lichen]

i tried to add noise in my image in my photoshop

[sly acorn]

WHAT

NOT NOISE GENERATOR 😭

[errant lichen]

looks like this before

but u guys said it too soft right

well i tried to

[sly acorn]

Why did u generate that much noise wtf

[errant lichen]

increase the texture

and

sharpness

[sly acorn]

Ur making the image worse man

[errant lichen]

lmao

[sly acorn]

Noise doesn’t make it sharper lol

That’s not how it works

[errant lichen]

lmao

alright

[sly acorn]

Undo it

[errant lichen]

i tried

[sly acorn]

And use graxpert denoise

Ye

[errant lichen]

already did

[sly acorn]

Also, maybe lower ur iso

[errant lichen]

here

[sly acorn]

Try 3200 or 1600

[errant lichen]

3200?

[sly acorn]

He

Ye

But it depends

Gimme a sec, lemme find the website

What camera are u using

?

[errant lichen]

canon 1300d

no modded just stock dslr

[sly acorn]

Seems ur ideal should be from 800-1600

I would say do 1600

Next time it’s clear give it a go.

Maybe u will have less noisy cleaner data.

[errant lichen]

so i should start over?

[sly acorn]

Ye sure, just a test

U should always test things

Don’t delete this data

Keep it for the time being

And compare

[errant lichen]

man idk with my post processing

my workflow when i got the stacked data

[sly acorn]

U will get better don’t worry

Just watch good vids

[errant lichen]

i go to graxpert

tried to background extract and denoise

[sly acorn]

Do u color calibrate?

[errant lichen]

save it and autostrech it in siril

[errant lichen]

no

[sly acorn]

Dude.

[errant lichen]

💀

[sly acorn]

Thats like, one of the most important things

[errant lichen]

lemme try

[sly acorn]

Use photometric color callibration

Are u on pc rn?

[errant lichen]

yea

[sly acorn]

Don’t do it with ur fully processed image

Do it after background extracting only

[errant lichen]

what does it mean

[sly acorn]

Might give a weird result after fully processing and innacurate

[sly acorn]

Wdym

[errant lichen]

soo when i got the color calibration

[sly acorn]

It’s a profess

U enter ur object

It asks u

And ur pixel size

And ur focal length

[errant lichen]

kkk

after that save it into fits file?

or tiff?

go to graxpert?

background extraction in there?

[sly acorn]

Pixel size for ur cam is 4.30

What mm focal length do u use

[errant lichen]

300

70-300mm

[sly acorn]

Yes

[sly acorn]

Ok put that

Btw, if ur doing untracked, I reccomend u to do a shorter focal length and use longer subs

[errant lichen]

2 second?

i should try using 135mm focal length

[sly acorn]

Ye that’s good

I would never reccomend 300m untracked tho tbh

Just try 100-135 and try the longest subs u can without stars trailing

[errant lichen]

ill try ill try

clear skies in my city like once a month soo

ill have to wait 🙂

and i live in b9

[sly acorn]

@ornate spade did u react to this

Or is my discord tweaking

Cuz I got a notification

[ornate spade]

I plead the fifth.

[sly acorn]

[lusty mantle]

besides the giant bright around the star, the image is very good

[errant lichen]

Really?, thanks

I thought it was bad

[lusty mantle]

why?

[errant lichen]

Idk, its... just my feeling

Nvm

[pliant fractal]

Tried to get rid off walking noise

the one on the right is a newer one

[lusty mantle]

a lot better

[lusty mantle]

how you did it?

[pliant fractal]

moved the telescope every 10 pictures

but it didn't work very well if I saturate the picture it is a lot more visible

[lusty mantle]

hm

[robust drum]

300x2s with a dslr
any advice welcome

[pliant fractal]

Tried to put the two photos together didn't help

[errant lichen]

carina nebula 1 hour 30 minutes

got this data only for 1 night

ill take again tonight if its clear

[paper arrow]

got a long way to go for 3 hours

[errant lichen]

I use 70mm focal length now

[errant lichen]

Ill try 4 hours max lmao

well i try antares region rn

[paper arrow]

rho sucks untracked

need a fast lens and/or star tracker

[errant lichen]

yeahhh

idk, i did just experimenting

flame nebula also

i forgot to take dark

:/

[errant lichen]

well i did some reprocess of my carina nebula

i restack all my image, and i dont use flats

now i know the issue, because of my flat tho lmao

Idk how you guys think

[tidal tide]

something is really borked in your workflow

[errant lichen]

Lol

Nah idk anymore

[sly acorn]

[robust drum]

Help!
I got some data from a week ago but then ran into the problem
that no stacking software could stack my images due to the lack of bright stars…
anyone got tipps?
i cant increase the shutterspeed btw(high focal length)
advice welcome…

[paper arrow]

send a photo of the subs

[sly acorn]

@robust drum since he forgot to ping you
