On this page I collect my observations of the galactic emission nebula NGC 2237 (2237-9/46) called Rosette Nebula and the open star cluster NGC 2244 in the constellation Monoceros/Unicorn.
The open star cluster NGC 2244 is embedded in the Rosette Nebula NGC 2237-9 / 46. While the star cluster is bright and is said to be recognizable even with the naked eye, the nebula can only be seen if the sky is dark and, possibly, using a nebula filter.
