    Orion 2" Dual-Speed Crayford Refractor Telescope Focuser

    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.

    Questions & Answers

    Ask a Question
    • what is the diameter of the base which protrudes into the telescope body of the optical tube?I am attempting an upgrade of an older non Orion refractor  and i need to know if this will fit it.

      I took a measurement of that section of the focuser with our calipers & it is 3.8 inches.

    • Will this focuser work with my Celestron Advanced VX 6" Refractor?

      It will be a tight fit, but it should fit your Advanced VX 6" refactor. It is possible that it may scratch or chip the paint inside of the scope. I personally wouldn't recommend using this focuser for your scope.

    • I have a 120mm 8.3 refractor (Orion). Will it fit my scope?

      This focuser is meant to work with the following Orion refractors: ED80 Apochromatic refractor telescope ED100 Apochromatic refractor telescope AstroView 100 f/6.0 achromatic refractor telescope AstroView 120ST f/5.0 achromatic refractor telescopes SkyV

    • will this fit the Astroview 90

      The Orion 2" focuser will not fit on the Astroview 90mm scope.

    • Does it fit with orion 80mm shorttube? Should i get any extra screws or something else?

      Unfortunately, this is not designed to work with the Orion 80 Shorttube.
