90° Everbrite Diagonals
Whiter and brighter images. In a nutshell, that's the benefit of Everbrite mirror coating. This exotic, dielectric, non-metallic coating is 99% reflective across the visual spectrum, resulting in one of the "whitest" and most natural images available. The coating is carefully applied to Pyrex with a surface accuracy of 1/10 wave flatness.
To ensure performance, each mirror is optically inspected by the manufacturer under conditions far more critical than those used in typical telescopes. In this way, TeleVue can ensure that Everbrite will allow your telescope to operate to its full potential.
The Everbrite is offered in 1¼" and 2" models. The diagonal bodies of each are machined from solid blocks of aluminum. Permanent alignment is assured. The one-piece body construction also means that heavy fittings cannot force the diagonal body to "unscrew" from the barrel as with other brands. The 1¼" and 2" models feature brass clamping rings, anti-reflection threads, and 1¼" and 48mm filter threads, respectively.
