Product Details

GSO's 2" SCTmirror diagonal is an excellent alternative to higher priced diagonals for those on a budget or just getting started in the 2" format.  This diagonal features Al + SiO2 coatings with 92% reflectivity across the visible spectrum and a 1/10 wave mirror. This GSO diagonal offers excellent mechanical and optical quality at a great price.

You can attach this diagonal directly to Schmidt-Cassegrain telescopes and many Maksutov-Cassegrain telescopes, as long as there is a SCT male thread on the telescope. The standard SCT thread is a 2"x24tpi thread.

A 1.25"-2" adapter is included so you can use this diagonal with 1.25" or 2" eyepieces. The 1.25" and 2" holders both feature a brass compression ring, so your eyepiece barrels will not be scratched by the set screw. The 1.25"-2" adapter is also threaded to accept 2" filters. The clear aperture is 38.2mm.

Includes 2 end caps. Weight = 1lb-6oz. (with 1.25" adapter); 1lb-3oz. (without 1.25" adapter). Made in Taiwan.
