There is more than one free program out there that will give you the required control of the camera and capture avi's for you. Give wxAstrocapture or SharpCap a try.
Plug the camera in and make sure it all works indoors before you go carting it outside.
Then go outside and capture some avi's. The moon, Saturn if your quick or Jupiter in the early morning.
You can't go past this
article as a start in processing.
The experts will chime in with more details.
