    POI Update for: Rosette Nebula Desc update: "The Rosette Nebula (also known as Caldwell 49) is a large, roughly spherical, 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 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter. The Nebula is quite large in appearance from Sol, and would be as large as the full moon if visible. The actual size of the nebula is approximately 100 Ly vertical, by 80 Ly east-west by 60 Ly north-south. The nebula is 5300 Ly from Sol. Due to the size of the nebula, several different NGC designations are given, and various names are associated with discovery; credit for observation and cataloging the Rosette Nebula can be attributed to at least Lewis Swift, John Herschel, and John Flamsteed."
