Multi-layered dielectric coatings that order to ensure a maximum reflection of 99% with the highest contrast and optimal sharpness for brighter, sharper images. Comes with dielectric coatings for the most light transmission possible. The residual stress in the plane mirror which can occur with the dielectric vapour deposition process is ruled out here.
- 90° Comfortable Angle
View the object at 90 degrees from the direction the telescope is pointing. This makes observations quite comfortable when the telescope is at or near the zenith.

Astromania 2" 90-degree 99% Enhanced Dielectric Diagonal Mirror uses multi-layered dielectric coatings in order to ensure 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 s crew-on systems, is compatible with both slip-fit and s crew-on mounting systems.

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.

If you are looking for a good quality diagonal for your SCT scope this one is really good. I was pleased with the build quality and the mirror is superb in terms of optics and this one won't break the bank. I was thinking about going with the 2 inch Celestron diagonal because of the twist lock similar to the Bader but for the price I don't mind the traditional screw type connector as it does have the brass ring and I found it's very secure and solid able to hold a 2 inch eye piece with no issue. It is excellent value for the money. Well built with no regrets on this purchase.

Received the product today and noticed it looks used. While not a huge issue, I expect to have a NEW product when purchasing it. It has several dings on the body. The mirror appears to be fine so I'll use it.
