Pinwheel Galaxy
Astrophoto M101 Pinwheel Galaxy Clear Sky 14.

Lessons Leaned
Some alignment issues and being very tired lead to only 1,5 hours exposure time.
Star-Alignment or even finding the object after slewing to the object is still a huge problem for me. But there is hope on the horizon: Platesolving!
