Description

This is the first completed narrowband project with the new setup. While the framing is not ideal due to poor alignment over multiple imaging sessions, pretty happy with how it turned out.

This is a false color image shot using Sii, Ha, Oiii filters and combined in what is known as the hubble pallet. In total accounting for just over 8 hours of exposure time capture on the nights of Feb 8th, Feb 9th, and March 3rd.

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 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 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.

Description: Had another go at processing. This one with new framing and some more contrast which may now be overdone. It's funny how every time you process the same data you always end up someone else.
