For prime focus I use a Baader 2" to 1.25" adaptor, and this has the obligatory T thread around the top, as do some other adaptors.
For eyepiece projection you need the T thread, but also an adaptor that provides a place for the eyepiece, and for best effect this position should be adjustable. If you try prime focus you can also use a barlow to increase your image scale, with the same requirement, a T thread at the camera end.
Onto this T thread you then attach the required camera T adaptor, and this is specific to your camera lens mount type, ie, Nikon, Canon, Olympus, Pentax, Minolta, etc.
