Yes Ray, I was struggling with colour banding on this image. My 1100D (and probably others) is very noisy at summer temperatures. This summer was particularly hot at night with temps consistently in the high 20's which brings out all the warts.

One way of combating banding and other uneven cmos illumination is to rotate the camera 180 degrees and shoot an equal number of subs. This helps smooth out uneven sensor illumination. But I didn't have the sky time to do it. We are back into showers now and the only time we seem to get a good sky is at full moon!
