The Event Horizon Focuser (EV) is a low-profile, friction-drive focuser designed for both the amateur and professional market. The highly acclaimed Crayford design permits tolerances up to 100 times better than conventional rack-and-pinion focusers. Zero image shift and zero backlash makes it fantastic for visual and photographic work and a must for CCD imaging. The modular design makes changes and upgrades extremely easy to accomplish.

The Event Horizon EV-3 is a 2" black-anodized aluminum focuser with knurled knobs. The focuser lifts up to 4 pounds. Manual control is over 1.25 times finer than most rack-and-pinion focusers.

The Newtonian version mounts on a range of surfaces from a 7.25" diameter, or larger, tube to a flat surface.

Add the optional variable-speed Motor and Smart Focus, Digital Read Out (DRO) or Digital Focus Counter (DFC), for the ultimate focusing system. The EV is truly a masterpiece of engineering and workmanship that you will be proud to own for years to come.
