IC 447 is a reflection nebula located in the constellation Monoceros.[1] It includes several massive B-type stars and forms one end of the Monoceros R1 star-forming filament, with IC 446 at the opposite end.[2] IC 447 may have been formed by more massive members of the young open cluster Collinder 95.[3]
