This adapter is designed to connect DSLR cameras through a camera T-ring to telescopes with 2" focuser (eyepiece holder).

You connect one end of this adapter (with M42x0.75mm external threads) to a DSLR camera T-ring (T2 mount) which will connect the camera body in place of the camera lens, and insert the other end into telescope's 2" eyepiece barrel. You can then take pictures through the scope.

The 2" T-adapter by itself does not come with a T-ring to attach onto a DSLR. This is suitable for example where you already have the correct T-ring and just need the 2" T-adapter. Otherwise, please choose your camera mount type from the dropdown list to add that type of T-ring onto your purchase, together with the 2" T-adapter.

    Note: A camera T-ring is not included with 2" T-adapter ONLY option
