Russian made - excellent quality. This diagonal has a 2" outer diameter barrel for insertion into a 2" ID focuser. The interior of the barrel is treaded for standard 48mm filters (M48 x 0.75 pitch thread). The 2" ID eyepiece barrel of the diagonal is fitted with brass cinch ring (NOT setscrew).
It is rated at ~1/7 wave p.t.v. surface accuracy or better and has a mirror consisting of LK-5 glass (Russian equivalent of Pyrex) with 93-94% reflective coatings (aluminum coated and SiO2 protected).
It's in like new condition. Mirror and coating excellent and has never been touched. Dust caps for both ends of the diagonal are included. New one costs US$ 150 plus shipping (from ITE Astronomy).
Price: S$ 150
