Thanks, Kevin. The yellow is from the brightest Ha emissions. Searching for a technique to make straight Ha look more interesting when I was processing the Veil nebula mosaic I experimented with using the luminance to modify hue. I do it manually in PI with a couple of slightly hairy PixelMath expressions but when I get a chance I will write a script to automate it and make it easier to experiment with the settings.
