Though I haven't had a chance to compare it with other 2 inch diagonals, I'm quite satisfied with the optical quality.At least I can tell see the marked increase in contrast and detail compared to the stock 1.25 inch prism.I initially had trouble in SCT adapter parts, and while I tried to attach it firmly into my nexstar evolution 6 OTA, I broke it, perhaps by over tightening it, but the dealer sent me a replacement parts in a week free of charge.

Top quality diagonal. I used it on my Celestron C8 telescope. The unit is rather heavy but I already have a balancing system msde up of sliding weights attached to my C8 I use to offset the weight of the diagonal and 2" eyepiece.

Compression ring not brass - catches eye pieces, over priced. Cheaper at Highpoint Scientific even with shipping.

Beautifully constructed and feels like very high quality. Unfortunately I couldn't have a look through it as it would not thread onto my telescope visual back (problem was with my scope not the WO diagonal)

Performs like a champ in my 8" EdgeHD. The build quality is near the top for high quality diagonals. I'm a fan of William Optics from now on, as well as Agena Astro Products.

Outstanding diagonal. Very nicely machined, feels very nice and mounts cleanly. I really like this product. Would not hesitate to buy other William Optics products.
