I met Mark Wrigley, the leader of this project at the Maker fair in the National Space Centre a couple of weeks ago. Looks like a interesting project, I'm especially interested in the Raspberry Pi either controlling the telescope or being used as a camera. He has just started crowd funding on Indiegogo, here are the links if anyone is interested:
