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-1 is a 2" black-anodized aluminum focuser with rubber grip knobs and two-speed operation. The focuser lifts up to 8 pounds. Manual controls are over 15 times and 1.5 times finer than most rack-and-pinion focusers.

The 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. The focuser gives 1/2" of travel and is designed for fine focus after rough adjustment with the normal telescope focusing knob.

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.

Please Note: Although the EV1C can be plugged into the telescope''''s'' base allowing control from the Meade hand unit, you will have better control with the JMI hand unit. Our hand unit includes an electronic brake (not included in Meade systems), which stops the motor as soon as you quit pressing the keys, and linear voltage control for superior speed control. Also, older LX200 telescopes do not have enough power to properly run the motor on the low setting.

The EV1C focuser can also be mounted on any 2" drawtube by first inserting the adapters (included) as shown below.
