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.

To ensure performance, every mirror is optically inspected under conditions far more critical than a diagonal mirror is ever used in typical telescopes. In this way, Tele Vue can guaranty that the Everbrite will permit your telescope to operate at its fullest potential.

The Everbrite is offered in both 1¼" and 2" models. The diagonal bodies of each are machined from solid blocks of aluminium. Permanent alignment is assured. The one piece body construction also means heavy accessories can't force the diagonal body to "unscrew" from the barrel as with other brands. Both the 1¼" and 2" models feature brass clamp rings, anti-reflection threads and 1¼"and 48mm filter threads respectively.

The 2" Enhanced Aluminium mirror coating provides a 96% reflective surface across all but the extreme ends of the visual spectrum. The enhanced coating provides extra reflectance versus competing standard aluminium coatings. The final coating stage applies a tough overcoat to protect the aluminium. The diagonal body has the same features as the Everbrite. The Enhanced Aluminium 1¼" diagonal features a 96% reflective mirror coating. All diagonals feature brass clamp rings and filter threads. The Enhanced Aluminium diagonals are good budget alternatives, especially where a prism diagonal might otherwise be considered.

Erect Image Viewing

While star diagonals correct a refractor's inverted image, they don't correct the left-right orientation. For terrestrial viewing, choose one of these erecting prism to achieve a natural view.

Note that due to the path length of these prisms, they can't be used with Barlows or Powermate amplifiers. Not for use with Bino Vue due to weight limitations.

Tele Vue Erecting Prism

The 45° Erecting Prism works best at moderate magnifications. It can accept 1¼" eyepieces.

Tele Vue Porro Prism

The In-Line Porro Prism works with 1¼" eyepieces.
