Подкопила еще пару часов, подправила звёзды и убрала шумы.

Allow me to ask what was done in each of the programs? Because the first three both calibrate and stack, so such a mix seems a bit unclear.

A little bit of everything. In Siril, I worked on the background. In PixInsight, I refined the galaxy's sharpness and did the stretching. In Photoshop, I just adjusted the colors. I'm just getting the hang of PixInsight, and it's still quite challenging for me.

Stacking with DSS. It can be done in others too. But there I'm already processing the photo.
