Description

Combination of RGB and narrow band. I did not have luminance data for this one. Underneath the Ha and OIII data there is a nice RGB image of M27, but the narrow band kind of swamped it out. Still, I like the "wings" that the narrow band data adds.

Update: I can't stop "tweaking" this one. I was able to get rid of some of the background tiny orange stars and noise. I also brought out the narrow band detail a little more.
