Description

The title says it all.

I actually tried some different techniques such as using the Pixinsight NBRGB Script to combine Ha with red. I also tried processing each channel separately all the way through NR (usually my last step before the stretch.) The red/ha channel was so bright and saturated that I actually had reduce it prominence on both the HT and through Color Saturation tools.
