A new month and a new
AP Processing Challenge!
Starfield Steve has submitted his three narrow band
Ha, Oiii and Sii capture files of the Rosette Nebula, C49. This nebula is a collection of NGCs.
Wikipedia: The Rosette Nebula is an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. The cluster and nebula lie at a distance of 5,000 light-years from Earth and measure roughly 130 light years in diameter. 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 complex has the following New General Catalogue (
NGC) designations:
NGC 2237 – Part of the nebulous region (Also used to denote whole nebula)
NGC 2238 – Part of the nebulous region
NGC 2239 – Part of the nebulous region (Discovered by John Herschel)
NGC 2244 – The open cluster within the nebula (Discovered by John Flamsteed in 1690)
NGC 2246 – Part of the nebulous region
