Product Description

EV-1n  Event Horizon 2" Crayford Focuser - Newtonian Telescopes

 


The JMI Event Horizon EV-1n is a  2" black-anodized aluminum focuser with rubber grip knobs and dual speed operation.  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 focuser can lift 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 Variable Speed Motor,  Smart Focus,or Digital Read Out (DRO) for the ultimate focusing system. The EV is truly a masterpiece of engineering and workmanship.

 This Newtonian version mounts onto a range of surfaces, from a tube that is 7.25" diameter or larger, to a flat surface.  1.25" Eyepiece Adapter included.
