Tele Vue’s Long 2″ SCT Adapter (#ACC-0003) allows you to attach 2″ star/refractor-style diagonals to your SCT telescope. It screws onto the standard male SCT thread (2″ diameter x 24TPI) commonly found on the rear of many SCT telescopes, converting it into a 2″ barrel that fits your diagonal.

Designed for use with all Tele Vue 2″ diagonals, this adapter features a brass compression ring to prevent damage to diagonals from set screw marks. It also includes dual large locking thumbscrews with threaded extensions on the sides to reduce the risk of screws falling out.
