One of the first objects shot with a monochrome camera. The flat frames turned out unsuccessful. I didn't think there could be any nuances with monochrome and that they might simply not apply oO Of course, I found out about this after the fact and couldn't reshoot them, which is why I had problems removing gradients. Also, the number of frames is not large, which didn't allow me to completely eliminate satellite trails. However, this is not a representative work. But after decent processing, it turned out quite well.

I previously published this object shot with an updated setup. So you can compare these two works with each other. The only difference is in the cameras and coma correctors. But both here and there have the same resolution of 1"/px

Oops. I messed up and didn't mirror the galaxy vertically) And last time I didn't mirror it horizontally either) Too bad there's no rotation or mirroring in the editing.

Defects from bad flats don't really seem noticeable, but the satellite trails... I'd say, with that many frames they should be fairly well removed. Maybe it's a matter of the settings? Other than that, a very decent shot.
