The Parks 8" f/6 Superior Newtonian Telescope is a result of years of design, engineering, refining and manufacturing expertise. It features diffraction limited, full thickness primary mirror; Parks fiberglass tube; precision bearings; stainless steel shafts and quality components throughout.
New state-of-the-art, low voltage 12 VDC clock drive/drive corrector runs anywhere in the world without changing the motors or circuitry. Using less than .5 amps at 12 volts, the dual-axis drive corrector can be selected to run at lunar, solar or sidereal rates. Declination motor, declination reversing switch, and dual-axis hand control unit are included.
Also new is a spring loaded, quick release, anti-backlash declination tangent system with manual and electronic slow-motion tracking capabilities. The worm and gear are both lapped to increase accuracy, and are individually matched. A spring-loaded worm gear assembly assures 100% interfacing of the gears for superior accuracy.
