Description

The Rosette Nebula is a beautiful emission nebula in Monoceros. It surrounds a cluster of hot young stars known as the Rosette Cluster (NGC 2244).
This was taken with my unmodded Canon 550D. Without any filters.
Seeing 6/10. I plan on capturing HA signal on it the next clear night using my L-eNhance filter.

I brightened it up a bit. And used TGVDenoise to clean the image a bit. I also tried to reduce the stars. Mike

This looks more natural to me. I started from the beginning ( Integrated Stack). Made a combo Range Mask and Star Mask combined using Pixel Math, then saturated it to look more pinkish red rather than purple. Mike
