Focusing Eyepiece Holder 1.25"/T-2 (5mm focus travel), with three clamp screws for eyepiece fine centering,plus one screw for blocking unwanted focus movement.
This T-2 system eyepiece holder, means the user can rotate the clamped eyepiece or camera to reach focus and block the rotation with the added set screw. This greatly helps keep a stable focus during planetary imaging or any other task that requires a precise focus position.
The three set screws work against a brass ring so there is no marking on any 1 1/4" sleeves inserted into the clamp. At the same time, the three screws enable fine control of lateral movement of the inserted equipment - for fractions of a millimetre in fine-tuning the centre position of the target object.
Includes a 1 1/4" plastic dust plug.
