Description

A glance at our nearest neighbor: the Andromeda galaxy.

Shot in a single (short) night, from a nearby suburban location.

The original image is standard L-RGB.

Revision B. was enhanced with H-alpha.

I spent most of the imaging time on luminance, and collected some H-alpha near the end of the session. The stars around some of the edges were severely distorted due to tilt in my imaging train. Luckily, I was able to correct most of the distortion with PixInsight's MorphologicalTransformation tool.
