This newly designed 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. Aluminum eyepiece holder ring. 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. Accepts 1.25" eyepieces. Has 1-15/16" of focus travel. Racked-in height 3-1/4".
