Product Series

The Next Generation Focuser (NGF) 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. Add the optional variable-speed Motor and Smart Focus, Digital Read Out (DRO), or Digital Focus Counter (DFC), for the ultimate focusing system. The NGF is truly a masterpiece of engineering and workmanship that you will be proud to own for years to come. (U.S. Patent No. 5,303,090) The NGF-S and NGF-miniS are specifically designed for the Schmidt-Cassegrain Telescope (SCT). SCTs achieve focus by moving the mirror. This design tends to create image shift which is especially problematic for CCD imaging. The NGF-S and NGF-miniS achieve focus by moving the eyepiece, camera or other equipment at the back of the telescope instead of the mirror.
