JMI Event Horizon EV-1 Focuser: £316.60

Cassegrain Version without Motor

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. Dual-speed manual controls are over 15 times finer (small outer knob) and 1½ times finer (large inner knob) than most rack-and-pinion focusers.

The Newtonian version (EV-1n) mounts on a range of surfaces from a 7.25" diameter, or larger, tube to a flat surface.

The Cassegrain version (EV-1c) 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.

The motorized version comes with a hand control unit.
