NGC2237-9 is a fantastic nebular complex in the constellation Monoceros, much better known as the Rosette. This nebula is a birthplace of stars and also star clusters, as NGC2244, formed by 46 stars all very young. The cluster lies in the less dense part of the Rosette, probably because the gases were blown away from the strong stellar wind occurred during the first part of the cluster life. The Rosette is one of the most beautiful objects of the sky, and is very large, being extended for 61' x 64'. Image taken by my friend Alessandro Cipolat and me.
