I have for sale a brand new WilliamOptics 2" Dielectric Diagonal(Carbon Fiber). Selling is because it is much "bigger" than I expected. I think I prefer to stick to a 1.25" one.
The diagonal is never used, selling without the original WO 2" to 1.25" adapter(I need it for my telescope). But I will throw in a low profile GSO 2-1.25 adapter(as shown in picture. Its screw is missing, can be just used as a great dust plug).
