I would not recommend anyone start out with a long focal length scope, like the Edge HD8, or any other SCT. Guiding these scopes requires very good setup and understanding of what your doing, it is easy to get in over your head. They are also slow photographically speaking at f10 or f7 reduced. Imho a refractor of say 100mm would give a good starting point, alternatively a small reflector of no more than 8". Aim for a good fast f# to keep your exposure times as short as possible. This approach will minimise your frustration and allow you to actually produce results and learn.
