Parallax
Instruments |
|
For the past twenty years Parallax Instruments
have been making Newtonian reflectors. These are not "run of the mill" mass-produced
instruments! Their prices are relatively high due to the
expense of utilizing only the very best components
available! |

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. |
