Astromania Telescope Diagonal 2 Inch 90-Degree Diagonal Mirror 99% Reflective Dielectric Coating Erect Image with 1.25 Inch Adapter - Provide a Much Brighter Image Than with an Ordinary Star Diagonal

Astromania Telescope Diagonal 2 Inch 90-Degree Diagonal Mirror 99% Reflective Dielectric Coating Erect Image with 1.25 Inch Adapter - Provide a Much Brighter Image Than with an Ordinary Star Diagonal

• The 2 inch telescope diagonal features a 99 percent reflective surface; the optics are crafted from Pyrex glass; additionally; equipped with an SCT interface and a 1.25-inch adapter; significantly broadening the range of compatible telescopes and accessories
• Multi Layered Dielectric Coatings: Dielectric coatings on the super-flat mirror reduce reflected light loss; providing a surface with over 99% reflectivity for brighter and harper images; which is highly beneficial for astronomical observations
• Wide Compatibility: Suitable for refractors included Schmidt-Cassegrains; ACF; EdgeHD and Maksutov-Cassegrains; it can be connected to other eyepieces; barlow lens and filters; among other accessories; via a 1.25-inch adapter
• 90 Degrees Design: The Astromania 2 inch 90-Degree 99% Dielectric Diagonal Mirror adopts a 90 degrees design; which can provide you with a better observation experience during visual observation
• Premium Aluminum Material: It is constructed from aluminum alloy; which significantly enhances the star diagonal longevity; equipped with brass compression ring; non-marring compression safety secures the eyepieces

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.
