Comments:  The Rosette is a vast cloud or dust and gas extending over an area of more than 1 degree.  Its parts have been assigned different NGC numbres: 2237, 2238, 2239, and 2246.  Within the nebula, open star cluster NGC 2244 is situated, consisting of young stars which recently formed from the nebula's material.  These were just two of several attempts at these objects.  The earlier attempts were stymied by clouds and framing that was inconsistent from shot to shot.  I never managed to get two shots on the same night.  It's been a long, cloudy winter.
