Lovely Brian, nice and balanced.

Thanks John.

It took a while to finish this off. I was trying various methods of incorporating the Ha. Finally used PixelMath to subract red from the Ha data, leaving just Ha, making a new image, then adding the new image to the original red data. Sounds complex, but is quite simple really.
