Comments about Celestron Celestron 90° Angle Diagonal Mirror, 2" with XLT Coating for Schmidt-Cassegrain Telescopes:
Seems to work as advertised - but this is my first 2" diagnal, so I don't have a lot to compare.

Excellent diagonal for an SCT scope. Connects directly to rear cell using SCT threads. Eyepiece side comes with 2" - 1.25" adapter. Both sizes have compression ring clamps. Glad I bought it for my Nexstar 6SE.
