The GP2 equatorial mount comes standard with tripod and counterweight. It is easy to use and functions well for both the visual observer and astrophotography. The declination and right-ascension functions with 144-tooth aluminum worm gears allowing accurate tracking. Motion is controlled by included control knobs for accurate slewing. The polar altitude adjustment varies from 0 degrees to 62 degrees in altitude.

The GPD2 equatorial mount is the stronger and heftier of the GP mounts. With it's solid steel R.A. and Declination axes and brass worm gears this mount will hold up to years of heavy use. In order to assure accurate tracking for astrophotography the worm, gears are especially machined to a very high precision that minimizes periodic error.

The GPD2 holds almost 50% more weight than the GP2 and comes standard with tripod and counterweight. It is easy to use and functions well for both the visual observer and astrophotography. Motion is controlled by included control knobs for accurate slewing. The polar altitude adjustment varies from 0 degrees to 62 degrees in altitude.

The SPHINX equatorial mount and STARBOOK controller have been intelligently engineered for high-speed automatic location of celestial objects. It is now possible to explore the beauty of the night sky with greater ease and stability. The SPHINX comes standard with built in motors and the world's first star chart go-to controller, STARBOOK, with a large full color LCD display. The Sphinx's design is exceptional and the exterior styling is equally attractive.

Main features of the SPHINX equatorial mount: 180-tooth worm gears for fine full circle motion. 22lbs. recommended loading capacity for a wide range of optical tubes. Built in DC servo motors allow for improved motion of the polar axis rotation and reduce the need for heavy counterweights.

A retractable counterweight shaft provides easy storage and transportation. The mount comes on an improved SX-HAL110 heavy duty aluminum tripod. An optional illuminated polar axis scope can be easily added to the mount body.

Main features of the STAR BOOK controller: Large color liquid crystal display. (4.7 inch, 320x420 pixels, STN, 4096 colors) High Speed Internal CPU (32 bit RISC processor, 75MHz, 8MB SDRAM, 4MB Flash ROM upgradeable) Zoom-In/Out buttons for the color star chart display also control the motor speed. As you zoom in closer to an object on the display, the motor speed becomes finer and as you zoom out, the motor speed increases to cover larger distances.

Features and menu options are displayed on the large color screen and are navigated with simple buttons on the controller. The STARBOOK is easy to use and makes the SPHINX available to a wide range of ages and experience levels. A large astronomical database with 22,725 celestial objects is stored. A LAN Port within the controller allows for computer control and network connectivity. The STARBOOK is also compatible with an auto guider (including SBIG ST). The auto-guider port comes standard on all controllers.
