Image Critique/Feedback

[daring cedar]

Core looks way to overdone

[ripe magnet]

feedback pls

[sharp marten]

Could use a darker background, imo i dont like the colour palette you went for.

[ripe magnet]

I mean I don’t really get to pick the color palette, it’s not mono

[sharp marten]

Still fixable

Looks like a processing problem

[ripe magnet]

It could be a tad darker, but the palette is fine

I want to print it actually so I can’t make the background darker

[wild ocean]

happy 2000 messages

me has question

which is the best?

[bright prairie]

2 because its the most novel, 1 is probably the objectively best image though

[wild ocean]

yea the lagoon image is a banger
wasnt expecting it to be insane

just a shame my 20hrs mosaic on LMC was a flop

[bold iron]

nah i wouldnt count that a flop

although any non photographer would almost definately point to the lagoon

[wild ocean]

it wasnt as good as i wanted and has a lot of issues

[bold iron]

ima be honest doesnt look like something after 20hrs

[wild ocean]

exactly

[bold iron]

but not bad honestly

stars look a bit saturated

[wild ocean]

at lesat the starless was decent

[bold iron]

does LMC have any background ifn type dust around it?

[wild ocean]

yes

a decent amount

[bold iron]

how come it didnt come up after 20 hrs

like 20hrs is alot

[wild ocean]

light pollution and that i shot some at f/5.6 instead of 2.8 was lower in the sky as well

[bold iron]

were you shooting into a light dome or smth?

[wild ocean]

it was a mosaic so yea the 2nd panel was mainly done in the light dome

when i did panel 1 it was higher above the light dome so it wasnt too much an issue then

[wild ocean]

starless versions

[bold iron]

horsehead is the best for deepsky

[wild ocean]

horsehead is lacking int
stock dslr makes it suck

[bold iron]

what dslr do you have?

[wild ocean]

EOS 650D

[bold iron]

modify it urself

mine took like 3hrs

[wild ocean]

na. i use this for daytime imaging

[bold iron]

wait hold on lemme show u smth

[wild ocean]

im planning on getting mono by end of the year

[bold iron]

fair

It's part of the filter that I took off the sensor

All the red from the light is practically removed

[wild ocean]

nice

[bold iron]

The mod made a big difference

Plus I was lucky so the autofocus and sensor cleaning still works

Just the white balance is off

[bold iron]

Thatll be even better

[bold iron]

Maybe try the LMC like at the end of the year when it's higher up

Try get the IFN out

It's got potential

[wild ocean]

really want to do some stuff in orion... didnt get to do it earlier this year/last year due to weather

[bold iron]

A big Orion mosaic at 200mm would look fire aw

That background dust in the horsehead would also look fire after a bit more integration time

[sharp marten]

going for this soon

At 135mm

[visual holly]

SMC?

[honest vessel]

5min recording,pipp,autostakkert,registax

Very proud of this but how do i get better image quality

[wild ocean]

So close!
That is the LMC

[wild ocean]

Gear?

[honest vessel]

Uranus c with a heritage 150p

[wild ocean]

Pretty good. Instead of registax use astrosurface

Much more control over tools and more tools available

[honest vessel]

Alright ill try it out, thanks

[visual holly]

I didn't recognize it at that angle lol

[spark wave]

Why such crooked panels? O.o

[sharp marten]

near the celestial pole

[wild ocean]

darken the background

arcsinh black point adjustment

[gentle marten]

bring the black point in

saturate stars some more

other than that looking good

[dry blade]

Imma get more data tonight and will try to apply your feedback

[vague meteor]

some stars/bright areas oversatted

prettt insane

[bold iron]

The top left corner has artifacts from starnet

[ripe magnet]

need feedback

[tough heart]

[wild ocean]

yay my threads alive again

[weak dust]

3h
uncollimated newt
B5

[wild ocean]

11hrs on sculptor

[wild ocean]

background splotching = overdenoised image

and/or bad background extraction

[daring cedar]

is this a screenshot?

I can't zoom in

[wild ocean]

heres full res

[daring cedar]

idk is it possible to pull out a bit more color? it looks a bit pale

altough it might not be possible at this fl

[wild ocean]

possibly

hows the image overall tho

[daring cedar]

pretty nice, its not hard to go wrong with this. I like how the galaxy pops from the bg

[ornate yarrow]

Only thing I've noticed are dim stars with a green tint and brighter ones with purple fringing. Looks pretty nice apart from that

The amount of noise you left in looks adequate to me, too

[wild ocean]

[lilac meadow]

Thought this should go here too

-# mostly looking for feedback on the last two

[bold iron]

I feel like ppl are too scared to give feedback here

[bold iron]

Your background is clipped, don't push the black point so far. Put more exposure time, if you dedicate like even an hour, your photos will become immensely better.

[lilac meadow]

ty for the feedback

When I was stacking these I was going for a higher contrast image so I stacked them with that in mind, the curve adjustment I did to get that was just after I aligned and stacked them so this should be pretty easy to fix. (siril is my stacking program of choice)

I realized the second one pretty quickly, the last astrophoto there was exposed for an hour.

[bold iron]

Also check both your focus and your tracking

The stars are slightly out of focus and trailed

[lilac meadow]

oh I should probably mention

my setup consists of standard photography gear and a star tracker I had laying around collecting dust

[bold iron]

yeh that should work fine

for broadband targets like andromeda its not going to affect much

the cam might be straining the mini star tracker although your setup appears to be under the 3kg payload

[vivid hornet]

Do you guys know what causes this? I've captured flats frame, biases, and darks also, the single lights doesn't show any sign of dust yet I still get this result

I'm not dithering, is that the cause?

Like it gave me a scratch, I captured at bortle 9 so start from 40 degree from horizon, it starts washed out my stars pic

[bold iron]

Yes this is classic walking noise

It's not dust

It will be fixed by dithering

If you don't have guiding than use NINAs built in guider and set it to dither, you don't need to have a guider Nina will do it anyway

[vivid hornet]

I'm using DIY star tracker tho, dunno if it's going to work, maybe I need to manual dithering?

[bold iron]

Yeh

[vivid hornet]

Oohh, the black scars just disturb me a lot actually

I cannot process it

[bold iron]

Move it very slightly every few frames

[vivid hornet]

Can I do it every 10 subs?

[bold iron]

Yeah if you don't dither then no matter how much data you get it'll become worse

[bold iron]

How long are your subs?

[vivid hornet]

I can do only max 30s per subs

[bold iron]

R U using a DSLR?

[vivid hornet]

Yes

[bold iron]

Which one?

[vivid hornet]

Canon 1300D

[bold iron]

You can get magic lantern on that which will give you intervalometer settings and longer exposures lengths

[vivid hornet]

My setting was iso 800 f5. 6 and 30second shutter

[bold iron]

You can go up to 99 hour exposure with magic lantern although idk why you would want to go that high lol

It's open source and free

Go to the website and download it onto your sd card

[vivid hornet]

I can do bulb like 60 second or something without magic lantern, but I need to precise the polar alignment and the drift alignment

[bold iron]

Ah

Yeh do that

DSLRs have lots of read noise so the longer the exposure the better

Try get up to a 1m exposure, and dither every 7 frames or something

This will very much be a try and test thing though

See what works for you

Just as long as the pattern noise isn't layering itself ontop of previous subs too much you're good

I dither every frame with 5m subs but I don't think that's possible with you

[vivid hornet]

I think I need guidescope for this and upgrade my star tracker for go to capabilities

[vivid hornet]

I'll try I'll try

[vivid hornet]

Sooo this black scars is a walking noise?

[bold iron]

Yes

[bold iron]

Yeh

Nina handles everything for me

[vivid hornet]

Alrighttt alright I'll try dither next time

[vivid hornet]

Ahh I see.., I soon need to upgrade into eq3 mount since eq5++ it's really really expensive

And modify it into go to

Anyway thanksss for the tips, I appreciate it so much

[bold iron]

Yeh using the onstep kits

[bold iron]

There's the swsa gti

Used you can bag that for 500$ sometimes

There's also the juwei mounts, if as you've built the openastro mount then you can definitely also get the juwei

The juwei is also just 2 stepper motors connected to an onstep controller but will be much smaller and take higher payloads

No customer service though which is why you should have some prior experience with diy stuff before getting a juwei as well

[vivid hornet]

Sadly my country doesn't sell that thing.. Need to import from the other country, and it's very expensive because of the import tax

[bold iron]

Oh

🙁

[vivid hornet]

Open astro mount can capable of go to.. Hmm... Might be considering that thing

[bold iron]

Oh yeah saw that

[bold iron]

It's a nice project

[vivid hornet]

Yeahh... It's kinda sad, because my country isn't interested with astronomical things, so accessories like mount, dedicated astro cam, it's very rare... And expensive

[bold iron]

Ur from India yeah?

[vivid hornet]

No I'm from Indonesia

[bold iron]

Oof

Hmmm

I've been to indonesia

[vivid hornet]

If build properly, it really can get like 0.7-1.0+ RMS

[bold iron]

My cousin's lived there

Went to jakarta

[vivid hornet]

Yes I'm at Jakarta right now xD

[bold iron]

Nice place except the lack of astro stores 🙁

[bold iron]

That's good

[vivid hornet]

Reallll

[bold iron]

Maybe bintel might ship to you from Australia?

[vivid hornet]

Lemme check...

Doesn't ship to Indonesia sadly

I found this on Facebook eq3 from SCTW102 celestron, it's kinda of cheap, costs about 250 dollars

[bold iron]

I haven't done this goto conversion before so idk

I assume it's good cuz celestron's products should be the same synta products that skywatcher sells

[vivid hornet]

Alright, might be consider it

[dry blade]

@hexed ginkgo

[wild ocean]

revove

bring this back to greatness

[median sundial]

real

[vivid hornet]

Gimme feedback lol

[oak swan]

Is this Ophiuchus?

[vivid hornet]

Yeahh

[wild ocean]

Looks alright but its lacking...stuff idk how to put into words

[vivid hornet]

Lots of integration time??

[wild ocean]

processing wise it doesnt look right

this is mine for comparison

idk why its sending a 61mb image

[wild ocean]

tbh later this year i wanna get new stars for this image

im not a fan of how they lookk

[vivid hornet]

O_o

Damn must be processing issue...

[brave cypress]

Also yours lacks the ha

So colors are different

[vivid hornet]

Right...

[brave cypress]

But I agree it looks a bit weird, probably because it was shot in bortle 9 hiding the fainter dust

And of course processing

[vivid hornet]

Man it's very hard to process it lmao, because it is so dim

[vivid hornet]

Any feedback?

[brave cypress]

Sorry if that sounds harsh
Here's what I see:
Too much saturation
Stars sharpened too much (they're too small)
Not enough int (denoising artifacts, etc.)

Some stacking artifacts

Bge could be better

[wild ocean]

pretty deep fried

get more data

[vivid hornet]

It's fine!
For the stars I don't take the slider way too much tho
But yeah stars shape could be bigger?
Yeah for int it's only 1 hour and 15 minutes exposure tho lmao

[vivid hornet]

Alright!

I don't have any idea how it supposed to look like, so the color surround it wasn't a real color but rather a color artefact?

[wild ocean]

yes

most liekely stacking artifactx

[vivid hornet]

Weird... I align it very carefully

[brave cypress]

You see that line on the bottom right

[vivid hornet]

Yeahh

It's not much I think lol, so I leave it be

[brave cypress]

The stacking artifacts should be cropped out

[vivid hornet]

Alright I'll crop it out

[brave cypress]

Also, did you dither when taking the subs? There's a bit of walking noise

[vivid hornet]

I dither every 10 frames

I'm very limited setup

[brave cypress]

Ah alr :)
How much int was that

[vivid hornet]

Only using ogst, so I gotta manually dither

[brave cypress]

o

[vivid hornet]

1 hour and 15 minutes I believe, It wasnt that much

Yet I push the color lol, I should be getting more int soon

[wild ocean]

you'll always have stacking artifacts. generally should always crop your corners regardless if you can/can't see the artifacts

[vivid hornet]

i added 1 hour more integration tho i know it still very little

[brave cypress]

Niceee

[vivid hornet]

i dont know if im doing it wrong...

with the bge stuff

[brave cypress]

Try graxpert it'll be easier (don't use it on the long term though)

[vivid hornet]

i think it alot better

[wild ocean]

fair bit better but still needs a lot more integration

also your stars are very green

[wild ocean]

looks pretty good!
soemthing i'd do is a star reduction to highlight more of the gasses add using an arcsinh blackpoint adjustment to contrast it

[vivid hornet]

Alright I'll add more

[vivid hornet]

I haven't color calibrate it yet

[vivid hornet]

i added more integration time and tryna process it

3 hours and 20 minutes of exposure

i followed feedback you guys gave me

less sharpening on the stars, bge carefully and add more integration time

how you guys think?

[brave cypress]

Way better

[vivid hornet]

thank you!

[brave cypress]

There's still something off about it, int limits how much you can push the data

[vivid hornet]

Yeah soon I'll be changing my star tracker into eq platform and it can support guiding also, I'm limited to 15 second exposure with star tracker

[brave cypress]

noice

[wild ocean]

Muuuch better. Still, get more

[vivid hornet]

Yeepee alright I'mma add maybe like 10 hours

[wind hatch]

I’m gonna make a mosaic by adding a photo between them. Thoughts?

4h of exposure SHO both photos

Ik I need RGB stars btw

[visual holly]

Magenta star supremacy
(It's up to preference)

[wind hatch]

Nooooo

[visual holly]

You can also get more natural star colors by processing your SHO more green or teal

(Of course lots of people hate when I do that)

[wind hatch]

Yeah I have some techniques to make a more RGB star color through SHO but I was meaning to get RGB stars so I didn’t do that yet
