The YZ 2″ Diagonal is an Astro Dog favourite. It has a heavy, solid build, and is of the same quality of the 1.25″ version from YZ.
The YZ mirror diagonals feature superior optical collimation (this has been tested by the SRAA) and very fine mirror polishing for outstanding optical clarity.
You can insert both 1.25″ and 2″ eyepieces into the diagonal, and it slots into both 1.25″ and 2″ slots – a truly universal diagonal.
It features a compression ring for superior fastening.
Customer Review 3/8/2020 : “The diagonal performed admirably last night from my backyard. Everything was in focus right out of the box. Found the build quality of the diagonal to be superb (it’s built like a tank) and as you said, the mirror is very well collimated. Very clear flat views came through the eyepieces.”
