I've been working on this galaxy for a couple of days now.
Overall there are about 20 hours of data in this one, but Im struggling to bring out texture and colors.
I tried a few different ways, hope someone with more experience can help.
Here is what I do:
I stack L R G B separetely, than combine RGB and stretch and then combine pre stretched RGB with pre stretched L.
In the first image I applied PCC prior to stretching, and overall didnt go crazy with the stretch.

On the second image, I selected center of galaxy as a symmetry point for GHS, and overall went harder on the stretch. This one seems to have more detail but a little noisy and outer parts are not as visible

and last one, I tried adding more blue to color saturation to bring out blue flavor in the outter parts

What do you think? Any advice will be appreciated!
P.S.: Im using Siril 1.2.0
