Description
The Rosette Nebula (also known as Caldwell 49) is an H II emission nebula just to the east of the constellation Orion, in the constellation Monoceros. At its center, 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.
The cluster and nebula lie at a distance of 5,000 light years from Earth and measure roughly 130 light years in diameter. The radiation from the young stars at the center of the nebula excites the atoms in the nebula, causing them to emit radiation themselves producing the emission nebula we see. The mass of the nebula is estimated to be around 10,000 times the mad of the Sun.
This shot of the Rosette Nebula is an HaRGB stack of various sessions with a mix of the Optolong L-Extreme and L-Pro filters, as well as some with no filter, shot at exposure lengths of 180 and 300 seconds, totaling 5.5 hours. All were shot with an ASI2600mc camera on a Stellarvue SVX102T-R telescope and CEM70 mount.
