The JMI 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. Dual-speed manual controls are over 15 times finer (small outer knob) and 1 1/2 times finer (large inner knob) 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.
The Cassegrain version is designed for use on 6" to 16" Cassegrain telescopes (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 a rough adjustment with the normal telescope focusing knob.
The Refractor version mounts in many refractors having one of two different inside diameters of approximately 3.5" and 3.75". The following is a partial list of refractors that should accept the focuser:
- Celestron C4-R, CG-R, C6-RGT, Firstscope 102, Orion AstroView 100EQ / 120ST EQ, SkyView Pro 120, Synta/Sky-Watcher 100ED, 120ED, 120AR, 150AR, 102AR, P80ED-APO, P100 ED-APO, Vixen ED100Sf
All of the Motorized models include a hand control unit. Note: Although the Cassegrain Motorized model 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, some older LX200 telescopes do not have enough power to properly run the motor on the low setting.
