The Scope is impressive, the eyepiece and diagonal are good, but the finder scope is total junk. The finder scope bracket can be adapted to a laser pointer and the bracket itself is standard and will accept regular Orion finder scopes. Overall, this scope is a very good buy for both astronomy or spotting use.
