Product Highlights
  • Upright, Laterally-Reversed Images

Unlike others, Tele Vue prisms and mirror diagonals begin life as one solid chunk of metal-which is then continually refined to produce what you see before you now.  This is a huge asset because there's nothing within the prism or diagonal which can unscrew and cause a heavy, expensive eyepiece to drop.

Tele Vue's Everbrite diagonals provide whiter and brighter images than any other diagonal.  The exotic Everbrite coating is 99% reflective across the entire visual spectrum.  Painstakingly applied, the Everbrite is offered in both 1.25" and 2.00" models.  The bodies are machined from solid aluminum blocks, ensuring permanent alignment as well as not allowing heavy accessories to unscrew the body from the barrel.

90° Diagonals such as this render upright-but-laterally reversed images, which in turn gives a brighter image than if the device yielded an upright and laterally correct image.  This is important when you're trying to muscle every last bit of magnification that you can out of your scope given the object's size, the scope's aperture and the seeing conditions.

        Use on 4" Refractor with TeleVue eyepieces. The original diagonal was the weak link, now corrected by this Diagonal. Next...a Tak! Was not in stock and took a few extra weeks, but worth the wait.

          I say it is. Especially over what you get from a dealer telescope like Meade or Celestron. Every bit of light loss affects what we see and the stock diagonals have about 11% loss. So you are getting a 10% increase or retention over a stock diagonal. You can see the difference! Everything is brighter and clearer especially in an SCT where we need all the advantages we can get!

            Comments about Tele Vue 90-Degree Everbrite Mirror Diagonal (1.25"):

            When I put this baby on my traveller (my Meade LT-6) I discovered texture to the brighter nebulas even under light-polluted skies. The stock diagonal is marginally acceptable, but if you want to run 1.25 then the tele-vue everbrite gets it right. (Was that a pun?). Next week my LX200 eight incher shows up and I'm running a two-inch diagonal (Meade 5000 series). IT will have to compete with my other Meade optics....and the tele vue diagonal. But get the Meade HD-60 eyepieces before you upgrade the diagonal. You will love yourself for it. Quality eyepieces first.....then a top-notch diagonal. That's my advice. And always.....enjoy the views.....

              Comments about Tele Vue 90-Degree Everbrite Mirror Diagonal (1.25"):

              I use this with an 8" SCT and it's clearly an improvement over the stock diagonal. I've seen other dielectric diagonals that claim 99% reflectivity for about half the price, one for around $100 that looks as though it might have come off the same assembly line, but my experience with Televue has been very good, so I just paid the extra few bucks and went for one I knew would be awesome. It is, so I'm glad I got it. Living within Boston city limits, things like this make a big difference.
