Description

I couldn't resist to do some galaxy imaging during the last week. We had more than one week of clear skies in germany, that does not happen very often :-(

Unfortunately the images were taken in bright moonlight, not the best conditions for galaxy imaging.

Nevertheless, i did some test shots on M101 and liked the widefield view... so i started al little exposure session
