Description
The Rosette Nebula / NGC2244 is a large, circular H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The open cluster NGC 2244 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 some 5,000 light-years from Earth and measure roughly 50 light years in diameter. The radiation from the young stars 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 solar masses. The cluster of stars is visible in binoculars and quite well seen in small telescopes while the nebula itself is more difficult to spot visually and requires a telescope. A dark site helps to see it. Photographically the Rosette Nebula is easier to record and it is the only way to record the red color which is not seen visually.
Celestron C11 with Starizona HYPERSTAR - ATIK 490 EX color camera. Effectively about f2.0 and 580mm focal length. 12 - 5 minute subframes.
