Unfortunately TeleVue Everbrite 90degrees 2" Satin Diagonal is not listed by OpticsPlanet.
TeleVue 2" 90° Diagonal DSF-8002 has Everbrite dielectric mirror coatings for 99% reflectivity. In addition to higher reflectivity than a conventional aluminum or silver coated diagonal, the Everbrite coatings also provide higher contrast and resolution during critical planetary, lunar, and binary star observations.![]()
TeleVue Satin Everbrite Diagonal body machined from a single block of solid aluminum that means heavy accessories can't force the diagonal body to "unscrew" from the barrel. The TeleVue 2" Diagonal barrel that fits into the focuser or visual back is internally antireflection threaded for higher contrast. It is also threaded to accept standard 2 inch filter models.
To ensure performance, every mirror of 90° Satin Everbrite Diagonal from Tele Vue is optically inspected under conditions far more critical than a diagonal mirror is ever used in typical telescopes. In this way, Tele Vue Everbrite Diagonal will permit your scope to operate at its fullest potential.
