I don't think that you could get a better diagonal than this, it has a quality feel that's hard to describe. It works really well with my 80mm Evostar ED Apo and is a lot better than the standard Skywatcher Dielectric model. I don't know that there's much point in buying this unless you've got a reasonably high end optics on the telescope (like an Apo Refractor) but it's worth every penny if you do. The 99% retention over the more normal 90-92% really makes a difference.

Highly recommended.
