Description

The galaxy season has started: M81, the Bode Galaxy in Ursa Majoris was my choice for the last night with clear sky. Sometimes the guiding was not perfect in the night, but I am happy with the result. 9 hours with my Skywatcher 200PDS newton and my ASI533MC. I am experimenting with the preprocessing to learn more about PI. The inner core of this galaxy is very bright so you have to stretch it different than the rest. It is very colourful, maybe the color saturation is a little bit too much. I will try some other variants later.
