Product Overview
Upgrade the focusing precision of an 8 or 10 reflector telescope with our new Antares Low-Profile Dual-Speed Hybrid Reflector Focuser. Its new, innovative hybrid design incorporates the benefits of both rack-and-pinion and Crayford focusers to provide superb fine-focus performance for 8 and 10 reflector telescopes. Building on the rock-solid reputation and performance of the well-regarded Crayford design, a unique helical spur on the two-speed focus mechanism provides increased positive control of the drawtube while minimizing backlash and slippage. This allows the Orion 2 Low-Profile Dual-Speed Hybrid Reflector Focuser to hold heavy payloads of observing or astrophotography accessories without slipping, while still offering the smooth, backlash-free motion of the traditional Crayford model. This hefty focuser tips the scales at 14 oz. can hold over 16 lbs. (~8kg) of payload and still provide smooth, slippage-free motion.
With a low-profile racked-in height of just 58mm, the Hybrid Focuser features a built-in 43mm extension tube for enhanced versatility, and has a total racked-out height of 122mm. Featuring dual-speed controls; this beautifully machined focuser lets you achieve just the right amount of focus using its fine-focus knob which has an 11:1 fine-focus ratio.
Featuring a 2 drawtube, the Antares Low-Profile Dual-Speed Hybrid Reflector Focuser comes with a 1.25 compression adapter for use with high-power 1.25 eyepieces and 1.25 accessories. The main drawtube has 8 precision roller bearings to support smooth operation and a knurled focus lock knob. The fine focus knob boasts an 11:1 reduction in speed for those moments when you need just a minute adjustment to obtain perfect focus.
The beautifully machined Hybrid Focuser is a mechanical masterpiece that is a joy to use and gorgeous to behold. Lock it down for astrophotographic pursuits, or adjust the tension control for fine adjustments during observational stargazing sessions.
