This is a bit of a palette cleanser after a bunch of dark nebulae. NGC 752 is an open cluster in Andromeda. It contains around 300 stars and is 1,400 light years away. The cluster is just over a degree across so four full moons in a 2×2 grid wold occupy the same space as the cluster.

This is 16h 10m of RGB data. For all the technical details see astrobin.
