    You need two parts: a T-ring, and a T-adapter. The T-ring is simple: you need one for Pentax cameras.

    There are several types of T-adapter. Refractors take one that is typically marketed as a "universal" adapter.

    You insert the T-ring into the camera's bayonet mount instead of a lens. The screw the T-adapter into the T-ring. And then you insert the whole shebang into the focuser as though it were a diagonal. Note that you have to remove the refractor's normal diagonal first.

    Thanks Kathy NS
    I was thinking that was how it works but looking at them on line got to be a little to much I started thinking I must be missing something.
