The Evening
The second evening with my new little APO. Another evening of trying a lot of things. I wanted to see some of the objects i saw on the Facebook Astro-Groups every day.
Andromeda Galaxy, M31
I started with 20 photos at ISO 1600 with 120 seconds exposure time – unguided (!) – at the Andromeda Galaxy M31. The single exposure were unguided. Some of them were really nice:
I did the stacking with DSS using BIASES and DARKS and stretched the result with GIMP. Not all of the frames had those awesome round stars as you can see in the result.
