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 superb 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 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.
