Used Stellarvue 2" Enhanced Dielectric Mirror Star Diagonal - UT-12991 - SOLD

Are you tired of that flimsy plastic and metal diagonal that came as standard equipment with your telescope? Is it starting to come apart through use or doesn't hold a securely as it once did? Do you want to replace it with good quality without emptying your pocket? Then you need the Stellar Vue Enhanced Dielectric Mirror Star Diagonal.

There's nothing compromising about Stellarvue standards. This thick, precision, optical flat is within 1/10 wave tolerance. This mirror-based diagonal incorporates 99% reflective dielectric coatings on the mirror surface and all aluminum construction makes it not only light-weight - but durable too. You'll also find safety groove features that keep the diagonal from accidentally slipping out of the focuser and it's fully threaded for filters, too! Star diagonals are a critical component of any refractor. The performance of an otherwise excellent telescope can be seriously compromised using a diagonal that is misaligned or pinched. Stellarvue researched diagonal design and fabrication for two years before introducing our first 2" dielectric diagonal- and it shows in every centimeter of this 2" work of beauty.

Stop marring your good eyepieces with a set screw. Stop worrying about dropping the set screw in the dark when your fingers are cold! The Stellarvue Enhanced Mirror Star Diagonal utilizes compression ring fittings to keep your eyepiece securely in place. To ensure quality, each StellarVue Diagonal is personally star-tested, aligned and inspected by their technicians before shipping.

This is a definite upgrade over standard diagonals!
