Orion 1.25" Basic Rack-and-Pinion Focuser, with 1-15/16" of Focus Travel

The Orion 1.25" Basic Rack-and-Pinion Focuser offers all the precision most telescope users will ever need. Now with improved universal base made of durable plastic to fit Newtonians of 4" aperture and larger. Dual knurled focus knobs turn smoothly even with gloves on. A fine upgrade for a lower-quality focuser, or a worthy component for a home-built scope. It accepts 1.25" eyepieces and has insert for .965" eyepieces. It has 1-15/16" of focus travel.
