I was working on a mosaic of M33 and it went together okay but I could not seem to coax any color out of it.

Let me explain that I was not happy with the 'Master' integrations produced by WBPP so I took the 'registered' output from WBPP and integrated them manually. Which seemed to work fine except, again, all channels are EXACTLY the same!? The subs appear to have been de-mosaiced and I see three channels in the histogram, but they are identical!
Have a look at this histogram. (You can click the image, then click again for a close up view).

What am I overlooking?
