Most people take photos of DSO's, but while you've got the gear, why not photograph the moon. It's also technically fun. Using a cooled camera, I video the moon/Jupiter at 20fps at 3000x3000. Then using software, I only take the frames where there is minimal atmospheric distortion. With the remaining frames, you stack them to get a very detailed image of the moon/planets.
Look up the other gear from ZWO the maker of the seestar.
They have active Peltier coolers and you use mains power, a portable battery box, or the 12V output from your car. You also need to power a computer or laptop to capture the images.
Roboscopes like the Seestar are an all-in-one kit and have internal batteries that last about 3-4 hours (although for the moon you don't need more than a minute or so). The S50 can take uncompressed video, which you can then process as GP describes but, compared to a more powerful setup, the camera is 1920x1080 and uncooled, the framerate is limited to 30fps, and it only has a 50mm aperture.
