Crayford SteelTrack 3 "Focuser for Refractor

This focuser can be adapted to practically all telescopes, from refractors to Newton and SCT type, thanks to a complete set of adapters and extensions. Adjustable precision bearings are mounted on hardened and polished stainless steel parts that fit into the thick-walled aluminum tube. The large diameter sprocket disc is also mounted on a precision laser-hardened and polished steel rail. These manufacturing features provide ultra-smooth movement far superior to the rougher movements of aluminum bearing systems. Focus buttons and precision gear allow ultra-fine motion control without kickback. All parts are precision machined and their high quality makes this device an ideal addition to any telescope.
