Tele Vue Long SCT Adapter

Televue Long Schmidt Cassegrain Adapter for 2" Diagonals

Have you ever wished you could use a conventional star diagonal with your SCT telescope? Folks with multiple telescopes don't always want to have multiple diagonals, so Televue decided to create an adapter that will allow you to use a refractor/reflector style prism diagonal with your SCT - the Televue ACC-0003 Adapter.

Precision threaded to match your SCT's rear cell threads, the Televue Long SCT Adapter employs a non-marring brass compression ring to hold your diagonal in place and a "never lost" captive set screws.

NOTE: With some telescopes and diagonal combinations, the length of this adapter may allow the diagonal to contact the drive base when the OTA slews through the forks or at the zenith. As a rule, the Televue Long Adapter will need approximately 7" of clearance between the rear cell of your Schmidt-Cassegrain and the tallest point on your telescope drive base. For use with all TV 2" diagonals except the new "Short" Everbrite Diagonal, which takes the matching Short SCT Adapter (ACS-0004).

Televue Product Number: ACC-0003

Customer Note: As of 1/1/12, Televue has extended its warranty on eyepieces, barlows, powermates and parracors from 5 years to a LIFETIME warranty! This will be effective on sales on 1/1 moving forward only and is not retroactive in any way. The warranty will still cover optical performance, optical coatings, optical cementing, plus mechanical components and operation of the product. This warranty still applies to the original owner and a dated proof of purchase must accompany any warranty repair claim.
