So, had a quick crack a couple of weeks ago at using my wife's Nikon D3 (Unmodified) for AP to see how it goes, this is a stack of 42 frames of 10 seconds (From memory) at 6400ISO, unguided. A quick and dirty result here as I am not after comment on the framing, focus, composition, vignetting, processing, the obvious internal reflection artifact or anything like that, I just have a question below.

What I am curious about is the banding that is evident as soon as you stretch the data, this is visible in all the subs. The EOS350D I bought cheaply to have my first crack displays even more obvious banding though it seems less consistent. Is this an affliction I can expect to see with most DSLRs? With guiding I might be able to help stack it out a little by dithering but I see it much the same way as we do undesired traits when breeding ponies "If you don't want it out, don't put it in"
