Astromania 2" 90-Degree 99% Enhanced Dielectric Diagonal Mirror - Provide a Much Brighter Image Than with an Ordinary Star Diagonal
Description
Astromania 2" 90-degree 99% Enhanced Dielectric Diagonal Mirror uses multi-
layered dielectric coatings in order to guarantee a maximum reflection of 99%
with the highest contrast and optimal sharpness.The residual stress in the
plane mirror which can occur with the dielectric vapour deposition process is
ruled out here. This slip fit 2-inch diagonal with 1.25-inch adapter, plus the
Schmidt Cassegrain thread to 2-inch accessory adapter and other Schmidt
Cassegrain rear thread screw-on systems, is compatible with both slip-fit and
screw-on mounting systems. The optics are made with Pyrex glass and comes with
dielectric coatings for the most light transmission possible. Beside
eyepieces, a star diagonal is one of the most important accessories. What is
the use of a good objective or the best eyepiece if the star diagonal is
inferior? We recommend the Astromania 2" 90-degree 99% Enhanced Dielectric
Diagonal Mirror to everyone, including those working with high end
instruments. The star diagonal permits full illumination of 2” wide field
eyepieces.
