Description

NGC 2539 is an open cluster in the constellation Puppis. The cluster contains hundreds of stars eleven of which are red giants. The diameter of the cluster is estimated to be 24 light years and it is 4,400 ly from Earth (source: wikipedia). The name comes from James O`Meara (contributing editor for Astronomy Magazine) although I am struggling to see the 'Dish'. The bright star, 19 Puppis, located at the edge of the cluster is a foreground star located 477 ly away. It barely stands out against the background star field even after doing slight curves adjustment around the cluster itself. It is no wonder this cluster is often over looked as there are many other more impressive objects close by.
