Hi Robert,
If you're interested in a magnificent Live Video camera check out the Mallincam VSS,
http://mallincam.tripod.com/ - I bought one of these cameras and although initially I wanted to use it for live viewing and loved what I could see on my screen and was able to capture the video to disk and the process using programs like DSI Imaging and others, I eventually started to get into serious Imaging and found out that these cameras are for what they initially were made for LIVE VIEWING (Great for star parties showing the stars to the family etc), I did get some very nice images with the camera but to get really good images you can't go past a cooled CCD camera.
I've just purchased a QHY8 for imaging and I'll be putting the Mallicam up for sale in the next week or so.
So if you're really after a Live Video System go for a Mallincam they're more expensive but they're worth the extra money.
Cheers
Jim
