RosettaSCT LSHO Reduced


RosettaSCT LSHO Reduced

This is another close up of the center of a popular target (NGC 2244) in the core of the Rosette Nebula. This was taken with my new ASI6200MM-PRO camera, Chroma 3nm SHO filters and my Meade 10" ACF SCT.
NGC 2244 (also known as Caldwell 50 or the Satellite Cluster) is an open cluster in the Rosette Nebula, which is located in the constellation Monoceros. This cluster has several O-type stars, super hot stars that generate large amounts of radiation and stellar wind.
The age of this cluster has been estimated to be less than 5 million years. The brightest star in the cluster is 12 Monocerotis, a foreground K-class giant. The two brightest members of the cluster are HD 46223 of spectral class O4V, 400,000 times brighter than the Sun, and approximately 50 times more massive, and HD 46150, whose spectral type is O5V, has a luminosity 450,000 time larger than that of our star, and is up to 60 times more massive, but it may actually be a double star.
