Orion 2" Dual-Speed Crayford Refractor Telescope Focuser


The Orion 2" Dual-Speed Crayford Refractor Focuser provides a simple, yet profound performance upgrade for your favorite Orion refractor telescope. The high-quality design adds fine focus adjustment ability with a ratio of 11:1 to your refractor. Eleven turns of the fine focus knob equals one rotation of the coarse adjustment knobs, allowing you to view even the most complex targets with acute precision. You'll be amazed at how much detail can be coaxed out of celestial and terrestrial targets with the addition of fine-focus control. Crayford style focusers offer smooth, backlash free focus adjustment by virtue of their gear-free design. Friction applied between the focus adjustment axle and a flat surface on the focus drawtube keep focus adjustments precise and accurate. The Crayford style design virtually eliminates focus errors related to backlash and flexure. Since the amount of applied friction is adjustable, even relatively heavy visual or imaging accessories can be used with the 2" dual-speed Crayford Refractor focuser with optimal results. The focuser features a built-in dovetail finder scope base for use with any Orion reflex sight or finder scope, and includes a 2" to 1.25" adapter for use of 1.25" diagonals, eyepieces, and accessories. Attaching the focuser to your Orion refractor is simple, and thorough installation instructions are included.
