Review Summary

This 60 degree diagonal is a solution for birding with astromical telescopes. Its reflectivity is so nice (99%) that the image is as bright as non-attached it. Compared to present decent 45 degree erecting prism, the televue stands out especially at more than 60x power. I can get sharp image at 100x at my C90. And the 60 degree angle is much better than 90 degree diagonal for birding. No more neckache! It is expansive but it worth every penny!

This is an entirely new angle for Tele Vue! It's a real breakthrough for birding and terrestrial viewing; the perfect combination of comfort and performance. Al came up with this very desirable accessory while playing at the Winter Star Party. We feel this new diagonal will combine Tele Vue performance and optimal ergonomics. Like a 90 Degree diagonal, this yields images that are correct up and down, but reversed left and right.
