M31, M32, M101 - Andromeda Galaxy - 251019

The Andromeda Galaxy (Messier 31) is a spiral galaxy located in the constellation of Andromeda. It's approximately 2.5 million light-years from Earth, making it the nearest major galaxy to the Milky Way, and is approximately 220,000 light years across. Also in the same field of view are Messier objects M32 and M110, both of which are satellite dwarf galaxies orbiting Andromeda.

This wide field image was taken with my QHY268C on my AT60ED with 0.8x focal reducer. This was really just a test run, before buying a field rotator, so it's not framed as well as I'd like, and I'm not going to get any more time on it at this orientation, so I went ahead and stacked what I had. This is a stack of 318 one-minute unguided exposures processed in PixInsight.
