Description

NGC2244 - Rosette Nebula - Continuing clouds where I am so I went back to reprocessing some old data from this time last year.

14 hours total integration using Sii, Ha and Oiii 7nm filters. The Rosette Nebula (also known as Caldwell 49) is an 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 (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 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.

Title: Caldwell 49 - Rosette Nebula

Description: I have no idea why I thought the previous versions were ok. Still not 100% happy with this image as I really had trouble getting the blue in the centre to pop, but, enough mucking around with it for now.
