Focusing Eyepiece Holder 1.25-inch T-2 (5mm focus travel)
Focusing Eyepiece Holder 1'/4"/T-2 (5mm focus travel)
Basically, at one end there is a T-2 thread (female) and at the other end there is a standard 1.25" eyepiece holder (barrel) with three thumb screws that will secure your eyepiece via a brass ring, thus not leaving too much scratches on your eyepiece as well as it's a more symmetrical and safer way of securing your eyepiece.
After you inserted and secured your eyepiece with these screws you can turn the upper part of the holder around its axis; in this way you can move your eyepiece up or down (depending on the direction of turn) thus achieving fine focusing.
The movement is smooth and without play.
