I shot M31 back in October last year from the house (Bortle 8 skies) and only collected about half an hour of data. This time the combination of Bortle 2 skies at Fort Griffin and more time on the target really made a big difference.

The Andromeda Galaxy is one of the most distant objects visible with the naked-eye. It’s located in the Constellation Andromeda as the name might suggest, and is roughly 2.5 million light-years away. It’s on a slow collision course with our own Milky Way galaxy. Two satellite galaxies of M31 can be seen in this image. M32 is just to the left of center and M110 at lower right.
