First attempt at at the Rossette Nebula. This is an HII region in Monoceros. NGC 2244 is an open star cluster in the center of the nebulosity. The cluster was formed from the matter of the nebula and they ionize the surrounding gas making it glow. Solar winds from the cluster also interact and give it the “rose” shape. Someone told me once that it looks like a skull.
