About the TeleVue 90 Degree Everbrite Diagonal - 1.25"...
When it comes to outright optical quality, no one quite does it like the folks at Tele Vue. The TeleVue EverBrite Star Diagonal is now offered in both 1.25" and 2" models and are CNC machined from a solid block of aluminum. No inexpensive sheet metal or flimsy tubes screwed into a plastic body here. Permanent alignment of the interior optics is absolutely assured and the quality construction means it will fit every 1.25" or 2" focuser or visual back it meets - and every 1.25" or 2" eyepiece or threaded filter will equally fit. Adding heavy accessories won't phase the TeleVue EverBrite Star Diagonal. It's guaranteed to never come apart and both focuser and eyepiece barrels are antireflection threaded internally for higher contrast.
But it's what at the heart of the TeleVue EverBrite Star Diagonal - DPC-1250 that really matters. Inside the solid mirror housing is a pyrex mirror-type star diagonal which sports Everbrite dielectric mirror coatings for 99% reflectivity. For those who own reflector telescopes, you know that Everbrite coatings provide superior contrast and resolution. For the refractor and SCT, this means cutting edge images for lunar, planetary and double star work.
But quality doesn't stop there. Rather than use set screws to hold the eyepiece in place, TeleVue EverBrite Star Diagonal utilizes a non-marring soft brass compression ring to hold their precious cargo in place. This means no more nicks, or scratches in expensive eyepiece barrels - and no screws to lose in the dark. As always, TeleVue considers every angle their equipment is used at and a special channel is cut right into the barrel to act as a safety stop. This will keep the diagonal, and your eyepiece from falling should it accidentally loosen from the focuser.
This is the same star diagonal Televue builds for their diffraction limited telescopes, and is exquisitely crafted to fold light exactly 90 degrees. The TeleVue EverBrite Star Diagonal is simply top of the line and will give you the visual performance your Schmidt-Cassegrain, Maksutov-Cassegrain, or refractor telescope is capable of delivering.
