Did you see what somebody wrote about dark current in the Quickcam? I'm
not really an astronomer (although I do have a slight interest), but it
would probably interest you. I think it was possible to overcome it

The question that comes to mind is "Can these CCD devices be connected to
a video capture card?" I guess the above magazine would explain all, but
if you can provide an answer to this list I am sure many people would be
most grateful to you.

I guess so, although I would probably use IRC in these situations. After
all, it only takes 2-5 minutes to DCC Send a GIF or JPEG image.
Applications such as CU-SeeMe would be better for phenomena such as a
lunar eclipse, though, I suppose.
