Thanks Marc,
I have had a good look at the data and there seems to be a fair bit of noise, I strongly feel that the Gain setting for the QHY10 is set too high. I have gone back over my graphs for setting the gain and after hitting the QHYCCD site feel that I need to make an adjustment. As for the processing I had not run any sharpening but I had also not run any noise reduction. I've had a bit of a go in a repro here and hope that I haven't done too much.
Many thanks for the useful comment.
Paul
