Description

I wanted an SHO image of the Crescent area, but I like how an HOO rendering gives much better contrast between the Ha 'ribs' and the O3 shell. After combining in SHO, I masked off the Crescent and changed it to HOO, then proceeded with a normal workflow from there. I'm sure there are many revisions to come, but for now I like the achieved result.
