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.

Antares Heavy Lift Focuser
I purchased this Antares focuser 3 weeks ago , and was able to install it on my Meade 10 Inch Dob, took about 30 minutes for installation and collimation was perfect, The following night I tested it out and used a 2.5 lb 30MM ES 82 DOF EP with a 2 inch Barlow lens and didn’t move at all , it’s rated for over 16lbs of equipment and it performs very smoothly with zero shift.excellent quality . I highly recommend this Antares low profile heavy lift focuser.

Great Focuser
Finally got around to installing this new focuser on my 16 inch Light Bridge scope. The Meade focuser that came with the scope was always sloppy and did not give a good image. This focuser is rock solid and after install with a good collimation the images are much better and what I would expect from a 16 inch Dob. I did have to drill new holes but was easy enough to do with a little courage.

Just a little too low profile but otherwise amazing.
I easily installed this on my Skywatcher 8" f/6 Newtonian. The screw layout was sufficiently different than the standard focuser mounting holes that it was easy to drill new holes without interference from the existing ones. There is absolutely zero play in this focuser. No dead band, and no slop. The 11 to 1 fine focus is actually more useful than I thought it would be, and I use it regularly. It's low enough to get prime focus on my DSLR! When focused all the way in, there is almost no intrusion into the light path. My only complaint is that it was too low prifile to reach focus on any of my eye pieces. I 3D-printed a 1/2" collar to rise the 1.25" adaptor out of the 2" tube a little more - just enough to reach focus, but still allow the compression ring action to work. I printed a 3/4" collar for my only 2" eyepiece for the same reason.
