Parallax German Equatorial Mounts
Parallax offers 4 models of equatorial mounts. The standard HD150, our fully computerized HD150C and HD200C, and the heavy duty observatory HD300C. Custom mounts up to 4" diameter shafts can be manufactured as special order. All mounts utilize stainless steel shafts and hardware for maximum corrosion resistance. All other components are machined of either high quality aluminum castings or solid bar. Our 10" diameter heavy wall aluminum pier is unmatched in strength with pier legs that wrap around the pier a full 60 degrees of the pier's circumference. We also specialize in custom welded steel permanent observatory piers in any size and height to suit your requirements.

LARGE CAPACITY
COMPUTERIZED
GERMAN EQUATORIAL MOUNTS
Parallax also offers our 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 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.
