NGC 2244 - Rosette Nebula
NGC 2244 Rosette Nebula in Monoceros. RGB-HSO Image with QHY600M The Rosette Nebula is a large emission nebula surrounding a cluster of young stars (NGC 2244) 5,200 light years distant from Earth and about 130 light years in diameter. The central stars are hot O-type stars that energize the nebula to 6 million K resulting in emission of X-rays and generating stellar winds that compress the surrounding molecular cloud to form new stars. This is an composite image formed from a RGB image taken with red, green, and blue filters merged with narrow emission filter images blended in that were taken with Hydrogen alpha (red – 656nm), Sulfur II (green – 672nm ), Oxygen III (blue – 500nm) filters.
