My experience so far (especially on really dim stuff like this) has not been very good with my unmodified camera. I've always put it down to huge light pollution and low signal causing my poor results. I don't seem to have the same kinds of issues on brighter objects though.
Mike, although this should not make any difference (in theory), because you have the darks all scaled correctly, you did not mention taking/subtracting BIAS frames. It is very unlikely to make much (if any) difference, but it is a very quick process to take them.
In terms of your darks, how did you physically block the light? (ie camera off the scope, body cover on, or did you just cover up the incoming light path on the OTA)? The reason for the question is to eliminate any possibility that there may have been some kind of partial light leak during the dark taking process.
Neither of these is likely to be the culprit, but it's a process of elimination!
