The GSO Crayford M-LRA 2" eyepiece focuser is a precise and solid focuser designed specifically for refractors with a tube diameter of 86 mm. Thanks to the use of linear bearings and the Crayford mechanism, it ensures smooth and precise focusing, which is particularly important for visual observations and astrophotography.

The extension is equipped with a two-speed microfocus with a ratio of 1:10, which allows for very precise focusing, even in configurations with heavy cameras or accessories. Compatibility with focusing motors such as ZWO EAF allows for automatic or remote control of the focus, which significantly increases the convenience of work.

Made of anodized aluminum, the focuser is durable and resistant to field conditions. The standard 2" mount and the included 1.25" adapter allow for the use of a wide range of optical accessories.
