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 applied a custom SHO blend to the whole image, which served to blend the SHO and HOO areas, and proceeded with a normal workflow from there. I'm sure there are many revisions to come, but for now I like the achieved result. It might be a little blue, other versions have been more green... Criticism and areas to improve are welcome. The new LN process was used, which really helped my less than perfect data.
