Lots of amateur astronomers use Registax to do what is known as "Lucky Imaging". The idea is that you record a bunch of video frames, and hope that you capture some moments of good seeing, which you then carefully align and average to remove noise, and then enhance. I was playing around with a sequence of 1200 frames that I found online, and in my first attempt of using this program, came up with this image of Saturn. Not bad. I keep thinking I should do some video astronomy, but never quite get around to it. Perhaps that should change.
