Tele Vue 90 Everbrite Diagonal - 1.25"

The 90 Everbrite Diagonal - 1.25-Inch by Tele Vue: When it comes to outright optical quality, no one quite does it like the folks at Tele Vue. The Tele Vue Everbrite star diagonal is now offered in both 1.25-inch and 2-inch models and are CNC machined from a solid block of aluminum. Permanent alignment of the interior optics is absolutely assured and the quality construction means it will fit every 1.25-inch or 2-inch focuser or visual back it meets, and every 1.25-inch or 2-inch eyepiece or threaded filter will equally fit. Adding heavy accessories won't phase the Tele Vue Everbrite Diagonal. It is guaranteed to never come apart and both focuser and eyepiece barrels are anti-reflection threaded internally for higher contrast. Inside the solid mirror housing is a Pyrex mirror-type star diagonal which sports Everbrite dielectric mirror coatings for 99-percent reflectivity. For those who own reflector telescopes, you know that Everbrite coatings provide superior contrast and resolution.
