Tele Vue 90 Degree Enhanced Star Diagonal - 1.25"There's a reason why Televue products are considered the best in the business. The Televue Enhanced Mirror Star Diagonal provides a 90 degree angle for your viewing comfort... But supplies a whole lot more.
At the heart of the Televue Enhanced Star Diagonal - DSC-0125 is a mirror.. one with exclusive aluminum coatings that deliver an outstanding 95% surface reflectivity. To stop the coatings from eroding with time and extending the life of the Televue Diagonal, the mirror is then over-coated with quartz. Around it is a single, solid block of aluminum that was precision machined to precisely cradle the mirror housing and match all 1.25" focusers, visual backs, filters and eyepieces. No cheap metal tubes glued into a plastic housing... No stamped metal parts... The Televue Enhanced Mirror Diagonal is the real deal.
What's more, there's no set screw to mar your eyepieces or get lost in the dark. The Televue Enhanced Mirror Diagonal uses a non-marring soft brass compression ring to secure your eyepieces in place, rather than a thumbscrew that contacts the eyepiece barrel directly. No more nicks or scratches on your good eyepieces! Televue thinks safety first, and that's why their Enhanced Mirror Star Diagonal has a channel cut into the outside of the barrel. This extra features performs as a safety stop to keep the diagonal from falling. That's good news for those of us who have had a visual back or eyepiece holder set screw loosen unexpectedly!
This premium 1.25" diagonal is a worthy and visible upgrade for virtually any Schmidt-Cassegrain, Maksutov-Cassegrain, or refractor that uses a 1.25" prism-type star diagonal.
