Description

About 3h of HOS data. RGB=HOS looked good, but I liked the central color in the JC pattern, so I combined or crossed them as R = (0.5 * Ha) + (0.5 * SII), G = OIII, B = OIII.

I also noted that Mike Feigenbaum had used Dark Structure Enhancement in PixInsight on a recent Pleiades image, and I used it here. It adds some internal contrast.
