M42-Im curious what can can be pull out of this stack.

1 year into astrophotography so im still learning and trying to improve my processing/work flow. It would be nice to compare results with others. 2 stacks-5s exposure for core and 25s exposure for nebula. 250 fl and 2.9 micro pixel size. 4h total integration time. Moon ~85%

might try later

Here’s my edit

I did this on my laptop that isn’t color corrected so it might be a little chopped but

[timid quartz]

This is pretty good

[sage bronze]

why are there 2 files tho?

[still topaz]

to blend the core so its not blown

[still topaz]

I like colors. My version is a bit washed out

[ivory juniper]

The core on both isn’t completely blown out so you can just carefully edit it

Without blending them

That’s what I did

[still topaz]

Just 25s subs so both might be good

[ivory juniper]

Yes

If you were using more like 60sec + then maybe it would be blown out

Just as long as it isn’t on the subs

25s for Orion is usually fine

[still topaz]

Yeah I will need longer subs, I was using gain 200 to try how it performs

so i needed to cut exposures

[ivory juniper]

Well you don’t need longer subs exactly

Longer subs can help for the outer region of dust

But not for the core

How much integration did you get

[still topaz]

around 4h

[ivory juniper]

Oh yeah I see now with the moon

[still topaz]

Yeah that was the problem also:)

[ivory juniper]

Definitely do it without the moon and maybe double the exposure

Or more ofc

It’s looking good, just that dust needs more work

[frail heron]

only the nebula file no core file

heres more satuated

[timid quartz]

brotha did u stretch the stars at all?

the nebula looks flat and the bg needs some work, but the stars are a bit of a problme

[frail heron]

how could i get the nebula to look not flat?

[timid quartz]

use more contrast

and even if u want some dust dont push it too much as it's as bright as the mid brightness neb

[still topaz]

Unfortunatelly it was shoot under nearly full moon. I guess pulling out dust wont be easy if possible at all. Also 2h of data was shoot through top clouds cover. I couldnt do it and seems like others struggle too. As juju.ziggy said need more data, ideally without Moon on the sky. Probably gonna get more data next year. Orion is to low atm and at my location theres a sky glow at south-west.

[zenith hill]

it literally says why there are 2 files

[still topaz]

That looks nice (have to look at it again on my desktop when I get home) . Have you use both files? I can see 1 thing that is similiar to my version. Core is not blown but its a bit washed out. Any chance to share workflow?

[zenith hill]

Yeah i used both

I could share my workflow but unless you're using PI it might be a little pointless

[sage bronze]

lol

i don't know how to merge 2 files tho 💔

do u like normally stack em?

[zenith hill]

im not sure how youd do it in siril.

[still topaz]

Oh yeah im on siril

[still topaz]

I use photoshop. Siril cant do it i guess.

You basically line up both pictuers after processing, nebula on top with core as bottom layer, create mask and use brush to reveal bottom layer. Something like that

Just simple processing on core(bge, color, stretch,denoise). For nebula full workflow

Probably can be done in gimp if you dont have photoshop.

[sage bronze]

ohh

prolly need to learn that

[timid quartz]

@still topaz just a lil proof that its indeed possible to push dust and not get so much flat neb yes indeed hard i get it.

might retry tho i'ma try to get a better result

also just a lil dust visible tho, so get this in consideration of what i'm calling dust

[still topaz]

I agree. This was my first time shooting orion, I guess my expectation way a bit to high on that dust with just 4h of intergration(and shot in way less than ideal conditions).

[timid quartz]

yeah fr

but like its not bad

just not best thing ever

i've never gotten an image like that tbh, i have no good setup

[timid quartz]

@still topaz yeah much better than last time ig

[still topaz]

looks good:) are you processing in siril?
