I shot this from my backyard about a week ago...Not really setup for planetary and was using a consumer grade DSLR camera to shoot the video which was then processed. Tell your grandson much better planetary images can be had with an inexpensive web cam connected to the telescope. They'll deliver more frames per second etc. I tell people if they're interested to focus on the close big bright things first...Planets, Lunar, star clusters, then if they still want to pursue it, graduate later up to deep space stuff, galaxies, nebula etc...
