The Evening
The third evening was to photograph the Andromeda Galaxy. Something i learnd meanwhile was: Longer exposure times and longer exposure time in general. At least in comparison to the days before i did some longer and more exposures. And i tested the trial version of PixInsight using some guides from the web.
The Andromedagalaxy
I took about 90 photos. About 2/3 of them at 60s and the other third at 120s exposuretime. I had to sort out a lot of them, since I still did not guide, yet. All photos at ISO 1250. It’s clear, that i was still in my wild experimenting time.
Reading a few guides on the web using PixInsight and after finding a worflow using it for the Andromeda Galaxy i came out with this result.
