NGC 2244 is an open star cluster embedded within the Rosette Nebula, a large HII region in the constellation Monoceros located about 5,200 light-years away. The nebula itself spans roughly 130 light-years across, one of the larger star-forming regions in this part of the galaxy, with the young, hot O-type stars of NGC 2244 having formed from and now carving out a central cavity in the surrounding gas. The rose-like shape that gives the nebula its name comes from the shell of glowing gas surrounding this central cavity. NGC 2244/the Rosette is a favorite narrowband target, with Hα and O III filters (often combined in an SHO palette) producing the classic red-and-teal “rose” rendering popular in amateur astrophotography.

NGC2244 and the Rosette Nebula. The Rosette Nebula (also known as Caldwell 49) is an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The enclosed open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter.
