The Rosette Nebula

NGC 2237, HaRGB

March 3, 2016

Not very happy with this, but I’m in a bit of a rush to process to here it goes.

Object details: NGC 2237, otherwise known and the Rosette Nebula, is named for it’s resemblance to a rose. The open cluster NGC 2244 in it’s center has created a circular hole in the nebula. It is surrounded by Hydrogen Alpha dust (left corner, above the nebula).
