Rosette nebula in Ha, Hb, OIII and SII

By GABRIEL GIANNINI DE CUNTO

The Rosette Nebula is a region of interstellar atomic hydrogen that is ionized (H II) and it is located near one end of a giant molecular cloud in the Monoceros region. Closely associated with its nebulosity, there is the NGC 2244 which is an open cluster with several O-type stars, super hot stars that generate large amounts of radiation and stellar wind. The stars of this cluster have been formed from the nebula's matter. In this image I have tried a new processing route, making all the stacking and the beginning of the processing with the PixInsight and the final part using Photoshop.
