Thank you for sharing your photos - this is exactly what this project is all about! :-)
Pixel math in Siril was used to add narrowband H-alpha (Ha) data to the broadband RGB image.
That is, the pure emission signal can be isolated from the Ha data by subtracting the continuum contribution, allowing Ha to be added to the image without altering the color balance.
As a result, we obtain a large number of nebulae in M 31 that contain hydrogen-alpha.

I was planning to add hydrogen to my M33 using the same method, but I just haven't gotten around to it yet. By the way, the blue band (BB) has shifted toward blue in your version.

The BB didn't drift away—this is an attempt to make the colors more expressive with warmth and tone.
Thank you.
Thank you.
But there is a result in any case.
The H_alpha regions are well highlighted.
