JMI 2" Newtonian Crayford Focuser EV-3
The Event Horizon EV-3 is a 2" black-anodized aluminum focuser with knurled knobs. The focuser lifts up to 4 pounds. Manual control is over 1.5 times finer than most rack-and-pinion focusers.

The focuser includes a compression ring in the drawtube for holding telescope eyepieces and accessories without scratching the equipment. The adjusting screw presses against the ring which tightens around the eyepiece or accessory.

The Newtonian version (EV-3n) mounts on a range of surfaces from a 7.25" diameter, or larger, tube to a flat surface.
