William Optics USA 2" Dielectric Dura Bright mirror Diagonal for SCT telescope
US shipping only.
It's high quality 90 degree diagonal for Smidt-Cassegrein Telescope ( size 6" and larger).
It supports both 2" and 1.25" eyepiece sizes, and has compression ring lock.
Mirror is dielectric coated with 99% light transmission, and is 12mm thick.
Body is made of durable fine machined aluminum with Carbon Fiber inserts.
Mirror has some dust, tiny scratches, and one 1mm dent (see pictures #5, #6) on the surface (eyepiece part got accidentally dropped inside).
But it works excellent and delivers very bright and clear view.
