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, spacers, and an eyepiece), T thread adapters, off axis guiders, etc. 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.
