Andromeda Galaxy, September 14, 2015
The Milky Way's sibling looked really pretty this morning. Autumnal air made for good observing conditions. Photographed from Huntsville, AL.
I'm actually pleased as I can be with this image. It is the culmination of a lot of trial and error,and some (possibly unreproducible) experimentation with post processing.
The field flattener, better focus and longer exposures at lower ISO yielded a nicer image, by far my best to date.
Best 9 of 10 images stacked with DeepSkyStacker.
ISO 400
Exposure 90 seconds.
Prime focus through an Explore Scientific 80mm APO ED refractor.
Canon T3i, unmodded
Celestron Advanced VX equatorial mount.
Dark frames and light frames only.
