Rosette Nebula (NGC 2237) & Caldwell 50 (NGC 2244) in narrowband (SHO)

            RA: 06h 31m 54s, Dec: +04° 56' 59'

The Rosette Nebula (also known as Caldwell 49) is an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy, approximately 5,200 ly from Earth. 

The open cluster NGC 2244 (Caldwell 50) is closely associated with the nebulosity, the stars of the cluster having been formed from the nebula's matter.

Reprocessed with an additional 40 mins of subs.  Lost a couple of SII subs due to satellite trails through the nebula, which PI struggled to remove.  Planning on adding a further hour of data in the New Year once the Moon phase is more favourable.  Still trying to settle on a palette I'm happy with...
