What you are calling "telescopes" are those three things that do, indeed, look like telescopes......on a round wheel with three spokes. I don't remember what they are called. You should have a book with a picture of this that will show how they should be set.
Maybe what I've just said, though, will help someone else to understand what you are talking about. Meanwhile, I'll try to work it out for you, too. EDIT:
. It might help. The book in the game will make them more clear.
