The GSO Crayford M-LRA 2" eyepiece focuser is a precise and solid focuser designed specifically for refractors with a tube diameter of 112 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 tube is equipped with a two-speed microfocus with a gear ratio of 1:10, which enables very precise focusing, even in configurations with heavy cameras or accessories.

Solid construction made of anodized aluminum and precise workmanship guarantee durability and reliability of operation. The focuser has a standard 2" mount and a 1.25" adapter, which ensures wide compatibility with various optical accessories.
