Thanks Iceman,
In regards to combining them, I need to work on my processing skills, in this case blending with photoshop. I do have other images at different exposures taken at the same time, but I could not work out how to blend them nicely. I always ended up with a hard edge around the outside of the disk which I did not like. I need to work out how to get it to feather the overlay.
Also With the colour camera I am not sure there was any more disk detail. The only advantage of combining them with this camera would be to get rid of the RED outline that runs around the disk. As seen in that current image.

Interestingly enough the colour in this photo is due to a side effect of overexposure and the light leaking into the green and blue chanels on the CCD. When correctly exposed, the image is all red as HA should be. But when overexposed, light leaks through the filters on the CCD into the green and blue chanels, these are what added the colour to the disk. Technically it should all be as red as the solar extremities.
