Description

First image after some time. Unfortunately, from the light polluted city (Bortle 7 or 8, now for the time being) and with the moon more or less up.

I will rework this a bit again. The background was really blotchy. Maybe the camera, maybe the light pollution, so I was artificially flattening the background, but now it looks too clean in my opinion ;-).

A lot of images from another night were wasted, because this object needed very careful polar alignment. Otherwise I was getting constant drift (field rotation?!) despite excellent guiding graph from PHD. Ultimately, I have used PHD drift alignment method.

Description: Added more Lum frames and look more careful to select the best frames only. Completly redone with less noise reduction, so the background is not too flat (first verison looked artifical too me).
