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 (see below) 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. Add the optional variable-speed Motor and Smart
Focus or Digital Readout (DRO) 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.
