The Rosette Nebula in Narrowband

NGC 2244

A very large emission nebula in the constellation of Monoceros. It is commonly called The Rosette nebula because of it's obvious appearance to a rose. The open star cluster NGC 2244 lies in the center of the nebula and is fairly easy to see in a small telescope. It is believed that star formation is ongoing in this nebula region. This is a combination of 3 narrowband filters, Ha, SII, OIII and RGB stars blended into the final image.
