TeleVue - 2 inch 90 degree Everbrite Diagonal - Satin

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 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.
Features brass clamp rings, anti-reflection threads and 48mm filter threads.
