If you need a diagonal this is the one - affordable and very high quality. If you don’t need one, all the better.
Replacing an old (and I mean old) Meade prism diagonal with this Tele Vue can be compared from looking through a wall to looking through a clean window. Everything popped into life. The Opt team were excellent too, the diagonal was almost on its way before I even ordered it. A good product from a good store. Thank you
