More product information
This physically short 1.5” long by 2” diameter adapter tube allows the use of conventional 2” star diagonals (the kind that have a 2” diameter barrel that fits into a refractor’s 2” focuser drawtube) on a Schmidt-Cassegrain telescope's threaded rear cell. With some smaller aperture telescopes and some 2” diagonals, the diagonal may hit the drive base when the scope tries to swing the diagonal through the telescope forks. This can be a problem with some computerized scopes when they try to aim at the zenith while in the altazimuth mode. The short body of this adapter, combined with the TeleVue #7782PC short front 2” star diagonal, will add an extra 3/4” of clearance between the star diagonal and the telescope drive base. With most telescopes, this will allow the diagonal to swing through the telescope forks to aim at the zenith without hitting the drive base.

One side of the adapter is threaded to screw onto the 2” diameter rear cell thread of 5” and larger Celestron and Meade Schmidt-Cassegrains (and 7” Meade Maksutov-Cassegrains). The 2” barrel of a conventional 2” star diagonal slips into the other side of the adapter tube and is held firmly in place by a non-marring soft brass clamp ring that tightens onto the diagonal barrel without scratching. The thumbscrew that tightens the clamp ring is internally tethered in the adapter so it can’t be lost in the field.
