Description

Sh2-108 in SHO (Hubble) Palette. I had a heck of time settling on a color mapping for this ... the H-a is overwhelming but doesn't reveal much in the way of interesting structure. The combination I landed on was:

R: 1;.3*S2 + 0.1*Ha

G: 0.7*Ha

B: 1.0*O3 + 0.05*Ha

So, a touch of Ha added to the R and B channels, and toned down Ha for the G channel. Some of the remaining magenta was pushed towards blue or simply desaturated, but I didn't want to eliminate all of it ... it's what the data was saying. Gamma Cygni itself is a tough star to deal with. Anyway, feedback on colors, etc., would be welcomed.
