Also the histogram of the colours is different - I don't know if that matters but the red is shifted in the flats. I may need to use a different white balance for the flats?

Also it may be associated with the dew cap being used for the lights but not the flats. I will try more options - I'll get it right eventually.

The colour isn't important in the flats and it is just for removing vignetting, pixel to pixel variation and dust bunnies.
