Probably the most expensive diagonal on the Market. Sold new for $800.
I developed a tiny scratch on the bottom of the mirror. Tried to take a
photo of it, but its very small.
This diagonal is 1/20th 2 inch Quartz Star Diagonal Silver Coating. This diagonal
is built in the USA around a quartz flat with silver reflective coating and a
proctective quartz overcoat. This 2" diagonal will take a 2" eyepiece. Mirrors
are guaaranteed to have interferometry results of at least 1/20th wave. I'm
asking $250 OBO.
