The JMI Event Horizon EV-1cM is a MOTORIZED 2" black-anodized aluminum focuser with rubber grip knobs and MOTORIZED DUAL SPEED operation. The focuser lifts up to 8lbs.

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 (DFCC for Celestron SCT) or (DFCM for Meade SCT) for the ultimate focusing system. The EV is truly a masterpiece of engineering and workmanship.

This motorized Cassegrain version is designed for use on 6" to 16" Cassegrain telescopes (e.g. SCT and Mak-Cas) with standard output threads. It includes an SCT threaded output adapter to allow use of standard SCT equipment on the output side of the focuser.

One of the EV focuser modular bases is designed for Cassegrain telescopes. The most popular type of Cassegrain telescope is the Schmidt-Cassegrain Telescope (SCT). These telescopes achieve focus by moving the primary mirror. This design tends to create image shift which is especially problematic for CCD imaging. The EV Cassegrain focusers achieve focus by moving the eyepiece, camera or other equipment at the back of the telescope instead of the mirror.
