I'd like to help, Professor. I'll show you the new telescope my parents sent for my birthday. It might be good for the project because it can tell you all sorts of things, like how far away the thing is that you're looking at. And er, I think it may be able to see through walls, so you don't have to go outside to look, even. (At least, we were looking at it last night and we could see Mr Dawlish down on the 4th floor when we were in Ravenclaw Tower.)
