Parallax HD150C-O Computerized German EQ Mount - Observatory Model

Parallax Instruments HD150C-O Computerized German Equatorial Mount - Observatory Model

Parallax also offers the larger German Equatorials with the Astro-Physics GTO Computer System. With its exceptional accuracy and stability, this control system will satisfy the most demanding amateur and professional requirements. The features of the GTO System enables any celestial object to be located and tracked for hours with arc second accuracy. The new optional DigitalSky Voice system can easily be coupled to the GTO System.

The HD 150C and HD 200C are designed to be completely self contained systems. No additional hardware or software is required. All system controls are contained in the hand held keypad including the vacuum fluorescent display. The 7.15" x 4.1" x 1" controller incorporates laboratory accuracy electronics and self explanatory software.

The polar and declination housings of the HD 150C and HD 200C are precision machined out of type 6061 aluminum bar to exacting tolerances; so important to the demanding performance required of a computer controlled instrument. Large thrust surfaces and close coupling of the declination to polar housing junction assures strength and rapid vibration dampening.
