The 40d's are notorious for having banding problems. I have it in my 350d on occasion, when I use ISO 800 and stretch the image REAL hard. My opinion, ISO 1600 will do you better for faint nebula...and I don't see the banding in my 350d at 1600. FWIW...

I will try ISO1600 next time...people seem to be getting good results with it.

I'd be interested in your results at 1600 ISO Jeff. Shooting at 1600 guaranteed I'd get the banding. 800 ISO would be more hit or miss.
