This adapter allows you to attach 2" eyepieces and accessories to any equipment/adapter that has a male T thread (T2 mount). Common examples are telephoto lenses which can be converted into excellent finder telescope with the use of this adapter and an eyepiece, or T thread adapters. Some Maksutov-Cassegrain telescopes use a male t-thread on their rear cell, so you can use this adapter as a 2" visual back for such scopes.
This high quality adapter has a T2 female thread on one end and a 2" eyepiece barrel on the other end. Eyepiece barrel features brass compression ring. Total length = 40mm. Made in Taiwan.
