Reprocessed Image of the Rosette Nebula (NGC 6888) in H-alpha from my backyard in Victoria. The Rosette Nebula is a large, circular H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter.
