Thank you for sharing your photos - this is exactly what this project is all about! :-)
Does not rise above 15 degrees at the latitude of Adygea, so I shot it over several nights. A barred spiral galaxy with powerful star formation, located in the constellation Hydra. Distance about 15 million light-years. Diameter 115,000 light-years. Angular size 12.9'x11.5'.

How do you stack? As a single sequence, or with pre-calibration of each exposure and then stacking them all together? And how will you add Ha, using what formula?
I stack RGB separately, and Ha separately as well. Then I subtract Ha from R using pixel math in Siril. Here is a very detailed video on how to do this in Siril:

Regarding Ha – do you do the color calibration before adding Ha to RGB or after?
Photometric calibration was done after adding it.
But this is just a regular photo, by the way.
Just RGB, no Ha data yet((
