Hmmm, while a webcam based imager is unlikely to be anywhere close to
optimal, I would have sworn that I heard Ron Wodaski say that the Ex
View HAD chips where designed to almost not need dark frames during
Saturdays' NEAF conference on CCD imaging. I'm wondering if while
scribbling notes I missed some context....

Chris Their dark current is very low, but plenty high enough to
Chris require dark frames for exposures longer than a few seconds
Chris at ambient temperatures. But they can be cooled without
Chris regulation and not normally require darks.

Thanks for the info! And thanks Robin, too. That's probably the
context I missed, that temperature is key, so long as they are
adequately cooled, there is little dark current.
