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. Like a 90º diagonal, this yields images that are correct up and down, but reversed left and right.
60° angle, 99% Everbrite for terrestrial viewing. Image correct up-down, reversed L-R
Whiter and brighter images. Simply put, that is the benefit the Everbrite mirror coating. This exotic, dielectric, nonmetallic coating is 99% reflective across the full visual spectrum, resulting in the "whitest," most natural image available. The coating is painstakingly applied to Pyrex with a surface accuracy of a 1/10 wave flatness. The Everbrite is offered in both 1.25" and 2" models. The diagonal bodies of each are machined from solid blocks of aluminum. In this way we can insure permanent alignment. The one piece body construction also assures heavy accessories can't force the diagonal body to "unscrew" from the barrel as with other brands. Both the 1.25" and 2" models feature brass clamp rings, anti-reflection threads and 1.25" and 48mm filter threads respectively.
