Astrophotography Galaxy

Astrophoto: Pinwheel Galaxy – Messier 101 – 04/21

The Pinwheel Galaxy – One of the famous Galaxies for Spring evenings. I had to ignore moon to practise more in astrophotography.

The Clear Sky Evening

Astrophoto M101 Pinwheel Galaxy Clear Sky 14.
Tree or two weeks of clouds and no clear skies in sight. At the end i had to ignore the 85% moon and shoot something 🙂

Here is the high resolution result on Flickr:

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!
