Intended use: visual astronomy, medium magnification
Compatibility: telescopes with 1.25" focusers
How to use
Insert the 1.25" barrel into the telescope focuser and secure it with the focuser thumbscrew or clamp. Focus the telescope on the target using the focuser controls, then fine-tune the focus for a sharp image.

Use steady mounting and adequate collimation of the telescope to achieve optimal image quality.
Usage recommendations
Use the eyepiece with telescopes that are well-collimated and mounted on a stable tripod or mount. For planetary detail, ensure good seeing conditions and allow the telescope to reach thermal equilibrium. Clean the eyepiece optics sparingly with a soft brush or lens cloth and use a suitable cleaning fluid only when necessary.
