I was killing time while waiting for Thor’s Helmet to get into position, so I shot the Horsehead and Flame Nebula region.  I used Fitsworks to crop out the dithering artifacts and set a black point and do the initial color balance. Photoshop and some hue and saturation adjustments to finish it off. Then, one pass with color blotch action and one horizontal banding removal action later and this is how it came out.  A few other tweaks were done, too. Not too bad for the minimal effort and a full moon night.
