Event Horizon Focusers

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 (see below) 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.  Add the optional variable-speed Motor and Smart Focus or Digital Readout (DRO)
for the ultimate focusing system.  The EV is truly a masterpiece of engineering and workmanship that you will
be proud to own for years to come.
