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.
Parallax HD150 Standard, Non-GoTo, German Equatorial Mount with Digital Drives
The Parallax Instruments HD150 Standard German Equatorial Mount is manufactured with precision Timken tapered roller bearings for strength and smooth motions.
It features a fully adjustable worm to worm wheel mesh mechanism and worm gear protective shields.
Easily adjustable clutch tension knobs are incorporated into the Parallax Instruments HD150 Standard German Equatorial Mount, as well as a detachable stainless steel Declination counterweight shaft with safety stop.
DC stepper motors for smooth tracking and minimum current consumption and Losmandy dual axis digital electronics package with full featured, hand held drive controller and control panel. The weight capacity is approximately 150 pounds.
Parallax HD150C and HD200C 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.
Parallax HD300C Observatory Class German Equatorial Mounts
In an effort to provide extra large capacity mountings to the advanced amateur or institution, Parallax Instruments, Inc. offers the massive fully computerized HD300C German equatorial mount. These no compromise instruments are designed to deliver up to 300 lb. of load carrying capacity at a very reasonable price. Only the finest bearings, gears, and stainless hardware are employed for unmatched strength, rigidity, and tracking precision. The polar axis housing is custom manufactured for the customer's exact latitude at no additional cost as is the height of our optional welded steel observatory piers.
The HD300C instrument employs the Astro-Physics GTO Computer system with an electronics accuracy of better than 2 arc seconds. When mated to the high precision Byers dual axis Starmaster gears, DC servo motors, and high performance planetary gearheads, the result is a mount with incredible tracking capabilities.
