Condition:
This is a William Optics 2" Enhanced diagonal in excellent condition, with clean optics and body, with the exception of a couple of nicks on the 1.25" adapter. This is NOT a dielectric; this is enhanced aluminum diagonal with, we believe, a 95 or 96% reflectivity.
This includes the 1.25" adapter, both dust caps, but no box.
Description:
This diagonal comes with the 2" Enhanced Aluminum Diagonal and the matching 2" to 1.25" Adapter that allows you to use 1.25" eyepieces and accessories in the diagonal as well as 2".
The 90-degree 2" Diagonal is solid and well-built. It has an enhanced aluminum mirror with a 95-96% reflective surface. This enhanced coating provides added reflectance when compared with standard aluminum coatings, and the tough overcoat that is applied protects mirror and coatings. Finally, a resilient overcoat is applied to shield the aluminum.
