Description

I was disappointed with this considering it represents 12 hours of data. I think the OIII was just too weak. Try as a I might I could not get the colors right. Also, to my dismay I actually lost some of the detail that was in the unprocessed HII stack. I'm at the limit of my PI skills. Time to try an easier target.

I think I finally used: HII, 0.8*OIII + 0.2*HII, 0.8*OIII + 0.2*HII
