Televue 1.25" Everbrite Dielectric Refractor Diagonal


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 1-¼" 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 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.

Olivon 2" Mirror Diagonal


Some of the world's most expensive mirrors use Dielectric coating, which can distort the surface and cause aberrations in the reflected light. Though Dielectric coats cost nearly double that of Aluminum-coats, at Olivon Scopes & Optics, we use Aluminum-coats for all of our mirrors. The reasoning behind that is to provide the highest quality materials to produce the mirror, with super precise machines to make it super ultra-flat, and provide the best viewing enjoyment with a coat that doesn't distort your mirror over time.

If that reasoning makes sense with you, then the Clarion 2", 90 degree Ultra-Flat Mirror is what we would like to introduce to you. The mirror itself is manufactured by Synta, a super ultra-flat mirror, not found in some other so-called 'quality' diagonals in the market. With complementing 2" eyepieces, the Clarion is capable of allowing a wider field of view. The Clarion includes an adaptor to attach 1.25" eyepieces, and has another adaptor for use with refractor telescopes as well.
