Actually found out today that I can use my Q-guider (QHY5) to take videos or even imaging.
Took a bit of stuffing around with the drivers to make it work both in PHD (normal use) and a program called QGVideo. So I can get a decent frame rate and a pretty good resolution, save as fits or AVI. It's also mono. I think I'll have a play with that to start with. It's gotta be better than the neximage cam.
