Antares 2" Adapter, SCT Twist-Lock (T2TL)
Tired of threading your Schmidt-Cassegrain accessories on and off? Switch to a smooth 2" barrel with a T2TL Twist-lock; it's quicker and a lot easier in the dark. Works with any barrel design, smooth, grooved or tapered. Threaded for filters.
Use the T2 Adapter on any SCT for use with a 2" refractor diagonal or 2" eyepiece. The twist lock (TL) securely grips a 2" diagonal or eyepiece without leaving nasty thumb screw marks and also avoids loosening, tightening and losing tiny thumbscrews in the dark and in the cold.
