Sky-Watcher Dual-Speed 2-inch Crayford Focuser for Refractors

Sky-Watcher dual-speed Crayford for refractors: focus on the micrometer

The Crayford design focuses using friction rollers instead of gears: no backlash, no jerks, just smooth movement. The second knob with 10:1 reduction refines that tenfold, precisely what high magnification and astrophotography demand.

With an 80 mm extension length, a 2-inch mount with a ring clamp, and an adapter for 1.25-inch eyepieces, you can replace the standard focuser on refractors such as the Evostar 80ED, 100ED, and 120ED, as well as the Startravel series, with a merk model that offers greater precision.

Features

• Crayford design: backlash-free and fluid
