Description

After a long, long time, I had again dared to drag the heavy Celestron CGEM outside. Something like goto and autoguiding is a good achievement. I lost all PHD2 settings on my Astro notebook in March. I had to start all over again. But such challenges are the salt in the soup.

The images was developed without dark and flats. Only bias frames and the bad pixel map ensured this result. I had a pretty good night and was rewarded with lots of details.

The result shows a lot of galaxies around Messier 101.

- no darks

- no flats
