Description

The Soul Nebula is a well known star forming region in the constellation of Cassiopeia respectively in the perseus spiral arm of our galaxy. Lots of dust clouds and pillars make star creation a very interesting and good looking thing!

The image was taken at three nights with 10'-subframes at gain139. I wan't to try this for a long time and the result isn't highly disappointing.
Only the star shapes aren't satisfying for two reasons: first, in one night, the OAG was a bit shaky, so guiding wasn't perfect. But the results showed a lot of nebula detail anyway, so I decided to use it. Second, the use of the ZWO OAG leads to an annoying tilt in the upper left corner. This get worse after the last collimation. Feel free to suggest solutions or possible reasons.
I show three different versions of the same processing. Version B is only a cropped panoramic view (2:1), Version C is starless (Starnet++), but the biggest stars leave still some artifacts.
