 There are
            few nebula in the sky that so clearly display the transition
            from pink in the central regions to a deep red in the outer.
            This is caused by the fact that the inner most nebula is closest
            to the hot OB stars in the cluster and thus put out an additional
            Hbeta line in the blue. Further out, we only get the pure deep
            red of Halpha excitation. The nebula itself, NGC2237-38 surrounds
            the large and splashy open cluster NGC2244, a 4.8 magnitude elongated
            object with plenty of hot stars.

            
The field here
            is 2 x 2.5 degrees in size and is a richly stellar field with
            many colored stars.
