Messier 52 (M52, NGC 7654) is a rich open cluster of stars in the constellation Cassiopeia, discovered by Charles Messier in 1774. It lies roughly 5,000 light-years away (estimates commonly range from about 4,600 to 5,000 light-years) and contains on the order of 200 stars packed into a region spanning about 13 arcminutes, presenting through a telescope as a dense, compact swarm anchored by a bright yellow star near its edge. M52 is a favorite wide-field imaging target because it sits roughly half a degree from the Bubble Nebula (NGC 7635), an unrelated foreground emission nebula that lies much farther away in the same line of sight. The pairing lets astrophotographers frame a nearby star cluster and a glowing stellar-wind bubble together in a single exposure, despite the two objects having no physical connection.
