A single exposure with f=750 mm, f/5,0 T=15 sec and ISO 3200 1 exposure, 10 exposures combined and 50 exposures combined are treated in Photoshop similar. Combining exposures is done with freeware Deepskystacker or with Photoshop. Note the lowering of the noise when you combine more exposures. Theoreticaly it lowers by a factor SQRT(N) where N is the number of exposures combined But also note the systematic errors caused by tracking errors (notably in the 10 exposure picture)

For this I use only the (in this case) 50 exposure picture as it is. So I do not use "flat fields" and/or "dark fields" as is often done
