Tele Vue's Long 2" SCT Adapter # ACC-0003 allows you to use 2" star / refractor type diagonals with your SCT telescope. It attaches to the standard male SCT thread (2" dia x 24TPI) found on the rear of many SCT telescopes and converts it into a 2" barrel into which you can insert your diagonal.
For use with all TV 2" diagonals except the new Short Everbrite Diagonal, which takes the matching Short SCT Adapter (ACS-0004). This adapter (new version) features a brass compression ring so that inserted diagonals are not marred by set screw marks, and dual large locking thumbscrews with thread extensions on the sides of the adapter to minimize the risk of the screws falling out.
