Ron,

The camera I plan to use will be my Kyocera M400R, with its own video (AVI) format, 30f/s. I was using it for Moon and planet imaging in the past, and I still need to confirm it has enough sensitivity to capture 6m stars.... If not, then I have some other options, like small B/W CCD surveillance camera (PAL output, 25f/s) and USB capture interface ($9 on ebay, very good value: I tested it by converting some of my old VHS tapes, works OK...
