Thanks guys.

I considered reprocessing from scratch, but I'm too lazy. I used Deep Sky Stacker to get the alignment information between the two images (x=-58.7px, y=-43.5px, rotation .85%) and then I applied the offset and rotation in Photoshop to align the new Ha with the already processed RGB. Then I copied the red channel from the Ha image and blended it to each channel of the RGB image at 80%, 20% and 20% respectively. The idea of putting 20% in the green and blue created a simulated H-beta teal and it also preserves the star color better then just putting the Ha data in either the red channel only or using it as a luminance layer. I also did some post blend star repair to clen up some halos although there are still some start that aren't very natural looking.

Looked back at the original, like night and day-sweet work. When you added this new Ha data did you add it as a layer (I know the red chan./Ha substitution process) to your existing completed pic or did you have to go farther back in your processing to make it blend properly? Marc PS sorry for always picking your brain for processing tips.

And you should be pleased, well done. Love the enormous fov and the crazy number of stars...anyone feel like quoting Carl Sagan here?
