Description

Here is the Rosette Nebula in HaRGB.

I am still learning how to produce better images using this method. I am having some issues with colored halos around stars after combining the ha with the RGB. I believe this is in part due to the fact that I am using images from 2 different cameras, and 2 telescopes. I had some coma in the RGB data shot with the ED80. (The flattener wasn't a good match)

Overall I am happy with the look of this. I used the red channel of the H-Alpha data shot with the ED 102 as a luminosity layer at about 80%.

Any comments or advice is much appreciated!
