Schmidt-Cassegrain Thread Version
Instead of the 2" barrel with this mirror star diagonal features an SCT thread. You can attach this diagonal directly to Schmidt-Cassegrain telescopes and many Maksutov-Cassegrains, as long as there is a SCT thread on the telescope. Of course both mirror star diagonal come complete with a 1.25" adaptor and brass compression rings for both 2" and 1.25" size.
