Thanks everyone. I keep finding ways to improve on things. I think, that's OK only to find more things and ways to improve. But the feedback is great.

38 frames 3.5 hours exposures between 15 - 5 minutes.

Camera - Canon 1000D iso800. Lens - Canon 200mm at f/3.2. Pollution filter - Astronomik CLS-CCD filter. Master bias dark and flat - the flats were taken at iso100 and later calibrated with a 100iso bias. I made the mistake of assuming that a bias is just a bias and calibrating the flats with iso800, which is same as lights and darks.

No calibration of flats at all produced an image with significantly less banding?
