M 106 (NGC 4258)

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 a pretty good processing, it turned out quite decent.

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 have the same resolution of 1"/px
