Code: EV1N Hi-Precision Zero image shift 2-speed focuser for Newtonian Telescopes
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 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, Digital Read Out (DRO) or Digital Focus Counter (DFC), 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. The focuser lifts up to 3.64 kgs. Note: Mounting base hole spacing is 70 x 70mm - this will fit directly to directly onto the SkyWatcher 200mm(8").
