Great result Carl. I know Carl sweated blood and tears over this one. I hope the result makes it all worthwhile.

Hi Carl,
In relation to your problem above, load the RED master image into Photoshop first so that it will be the background layer. Then layer the H-a master image on top of the RED and (1) change the blending mode to LIGHTEN and (2) play around with the opacity from anywhere from 20 to 80%. Once you have something you like, flatten the two layers so that you will have a new RED master image and then proceed as usual in creating your master RGB and then layering the LUMINANCE on top etc etc.

Hi All,
Anthony that is the way I did it. But it still takes away from the image It over powers the H alpha parts. Maybe I over processed the H alpha data. I processed the image in photoshop using levels & curves.
I'm at a loss.

Thanks for all the comments
