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