The Session-Story of the Andromeda Galaxy
I struggled around with the flattener for a few months now and i was still not happy with the results. But i found a config that seemed to be ok for now and i wanted to test the performance in the field on a real picture. The Andromeda Galaxy was my target.
I had two evenings to see how it worked. The final picture is the only RGB result from the first evening. On the second evening i used the duo narrowband filter with the idea to show the H-Alpha regions. But i was not able to use that material in a useful way.
Here the high resolution Astrophoto on Flickr:
Lessons Learned – Andromeda Galaxy
- It is fun to just shoot some astrophotos.
- The flattener config is not that bad.
- Only one evening of RGB at F7.5 on M31 is too few.
- I am not able to use H-Alpha material on a RGB galaxy photo yet. So I will hopefully upload an update soon.
- I worked homofocal … more in another posting.
