Comments about Pro Optic Pro Optic 90° Mirror Diagonal, Dielectic Coating with 2" Schmidt Cassegrain thread.:
I'm going to come back later and comment on the optics, right now I just want to say this diagonal looks great and does fit the schmidt cassegrain scope. I had called Adorama and ask about this diagonal before because all the pictures show it as a slip on, and they ( Adorama ) said it does not have threads, so I ordered an adapter from another source and then ordered this diagonal, low and behold when it came it did have threads, so I've got an adapter that fits my 12" s-c, so now I can use my 2" williams diagonal that fits my 6" refractor just in case this one does'nt work out. Let you know how it performs as soon as I find out, which may take awhile since nights of really good seeing are very rare.

A very nice diagonal at a reasonable price! Well constructed, works perfectly on my LX90 SCT! The prism diagonal that came with the scope was not very good optically. This solved that problem!
