New 2 90 deg 99 Dielectric Mirror Diagonal for Telescope With 1.25 adapter full metalhas a 110th wave flat optical glass surfacesolid aluminum housingthreaded to accept standard 2 filtersThe 2 eyepiece holder uses a non-marring brass compression ring to secure your valuable eyepieces. The 1.25 adapter also has a non-marring brass compression ring. Both sizes of eyepieces may be used and are protected from dings and scratches that would result from a standard set-screw. This 2 diagonal works with any Refractor that accepts a 2 star diagonals. It can also be used with Schmidt-Cassegrain or Maksutov-Cassegrain with an optional 2 inch visual back See below. Dielectric diagonal is especially importantA standard aluminized diagonal has about 92 reflectanceAnd this decreases with time as the aluminum mirror surface ages. For the vast majority of the visible spectrumthe reflectance does not vary more than about 0.1 below 100And the dielectric surface does not age like aluminumThis combination leads to the equivalent of a little more light grasp compared to standard diagonals.

Standard 1.25'' diameterfit for 1.25'' focuser and eyepiecework with refractor and catadioptric telescopesnot recommended for reflector telescope. Fully coated lens come with dust coverkeep your lens clean for superior image fidelity.
