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 and contrast.
You can insert both 1.25″ and 2″ eyepieces into the diagonal, and it slots into a 2″ slot natively.
It can later be attached also to a 1.25″ slot by means of an optional adaptor ring (not included) then making it a truly universal diagonal.
It features a compression ring for superior fastening.
nb. Note that it is pictured with the optional 1.25″ adaptor, which allows it to slip into a 1.25″ slot
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.”
