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.
