This diagonal came with my C-9.25" Schmidtt-Cassegrain Telescope (SCT), which I bought in March, but I have hardly used it since I always use a different diagonal. As such, it is in pristine condition, has seen little use, and and is complete with both end caps, packing, thumbscrews, and the original box. I think it would make a nice upgrade for someone who needs a diagonal, or who already has a lesser quality diagonal. Please see photo.
It mates with the standard 1 1/4" telescope opening and accepts any standard 1 1/4" accessories.
