Adding Ha as a luminance layer is pretty unworkable in my experience. You can get away with a small amount sometimes and it will add a bit of detail but usually at the expense of rich and nice reds and colour in general (blues get damaged as well).

Hello Greg, I know the 'Salmon hues' you talk about very well, however I really cant see them here....at least not on my monitor
... my processing had many stages and was not as you described, My method is quite unconventional really. I used both Ha+R,G,B, and an RGB and also constructed a luminance layer out of all combined data.
Salmon hues come from an imbalance between the Luminance and RGB and is not a just product of Ha, you can quite easily get them with a none H-alpha Luminance layers too.....
