M33 in L(Ha+R)GB - processing in GIMP (for the Real Intelligence Challenge)

Piotr K.:
Hi guys, here is my tutorial showing the workflow for processing M33 data, shot with ASI294MM Pro camera in L, R, G, B and Ha, without any tools using A.I. It's for the Real Intelligence Challenge, announced some time ago by Mark from Deep Sky Detail YT channel

Here's the tutorial:

And here's Mark's annoucement of the contest:

Let me know what you think about the workflow - I'm always interested in learning something new

I really like the image! When I saw this post I wanted to try the challenge myself with no ai tools in pixinsight and here was the result I got:
M33 HALRGB
M33 LRGB:
M 33 HA ONLY:


I made these images using pixel math, brightness masks, Dynamic background extraction, and curve transformations. The HA was colored red with masks and added into there with masks and pixel math. You can see the noise in there because I did not know how much ai is used in pixeinsight's denoiser. I also did no deconvolution on the image because I do not know the ai limits on that. I feel like I could have gotten better star color but without starxterminator I felt kinda lost.

I'm wayyyyy better when I have AI help

How would your workflow look like with A.I. tools?

I was wondering about this myself - I only use A.I. tools for denoising (GraXpert) and star removal (Starnet). So for the galaxy it doesn't matter if I use A.I. or not - processing would be more or less the same.
