Baader 2" Clicklock Mirror Star Diagonal
New, In Box, I was unable to use this due to physical constriction of my GT81 mounting on my old setup, now I now longer need it.
Baader's dielectric coatings deliver an amazingly high 99% photo-visual reflectivity along with an extremely hard durable surface.
