The GM1000HPS mount is built for the demanding observer using photographic instruments up to a weight of 25kg – 55 lbs (counterweights not included). Movements are driven by two servo brushless motors, with timing belt reduction having zero backlash. Both axes feature a classic worm – wormwheel pairing. The wormwheels are made of bronze (B14), with a diameter of 125mm and 250 teeth, while the worms are built of alloy steel with a diameter of 20mm. The axes themselves are made of 30mm diameter alloy steel, for the maximum rigidity. The double dovetail mounting plate guarantees the maximum compatibility with many telescope manufacturers.

The electronics is housed in an independent control box, easily removable. The connections of motors, encoders and hand pad feature security lock screws. The mount can be controlled using the included hand pad, without connecting an external PC. The keypad is built in order to maintain the maximum readability in all lighting conditions. Both the display and the ergonomic keys, allowing for the use of gloves, feature a red backlight. An heater keeps the display warm for usage below freezing temperatures.

The mount can be controlled using the most common software packages by connecting it to a PC with the RS-232 serial port or the Ethernet connection, via the proprietary 10Micron ASCOM driver or the Meade compatible command protocol. Furthermore, a dedicated software (also included with the mount) can be used to create a “virtual hand pad” replicating exactly the functions of the physical hand pad. The RS-232 port can also be used to control an external dome. This flexibility makes the GM1000HPS an ideal mount for observatories and remotized observing sites. The object database contains many star catalogs and deep-sky objects up to the 16th magnitude. Solar system objects can be tracked so that their motion is compensated with respect to the stars. You may load orbital elements of comets, asteroids and artificial satellites into the mount, so that these objects can be tracked directly using the hand pad (without any external PC).

HPS

All 10Micron GM mounts come with a feature called HPS – High Precision and Speed – an innovation from 10Micron. They feature traditional worm and wheel pairs, and with the latest state of the art encoder technology allows these mounts to perform at the same level of precision as professional direct-drive mounts.

The GM1000 features two high-precision proprietary (1/10th arcsec resolution) absolute encoders that are mounted directly on each axes. These encoders provide very impressive high precision GoTo pointing (typically to within 20 arc secs) and tracking accuracy (<1 arcsec).

Features

The Mount

The GM1000’s Right Ascension and Declination axes, both of which are made of 30mm diameter alloy steel (for maximum rigidity) are driven by two servo brushless AC motors, with a belt drive reduction with automatic backlash recovery that results in a backlash-free system. Both axes feature classic worm and wheel pairs; the worm wheels are made of (B14) bronze, with a diameter of 125mm and with 250 teeth. Each worm is 20mm in diameter and are made of alloy steel.

The mount features a dual Vixen/Losmandy type dovetail mounting saddle clamp. This allows the mount to have a wide compatibility with many telescopes from different manufacturers. Once you have mounted your telescope and equipment onto the mount, you can then use the electronic balance function to achieve perfect balance in both RA and DEC without unlocking the clutches.

The GM mounts can track 30 degrees/2 hours past the meridian and means that long duration astrophotography is easily achievable. The absolute encoders allow extremely high tracking accuracy (<1 arcsec), and means that autoguiding is not necessary. However, the GM mounts do allow the use of an auto-guider, if needed, through the inclusion of a standard ST4-compatible guide port.

Object Database

The built-in object database contains celestial objects from the major astronomical catalogues (e.g. Messier, SAO, NGC and more) down to 16th magnitude. The mount’s tracking rates are adjustable depending on the object being studied and the orbital elements of comets, asteroids and even artificial satellites can be loaded directly to the mount (without the need for an external PC), so that these celestial objects can be followed across the sky accurately.

Electronic Control System

A PC is not required to operate the mount as GM mounts can be controlled using the supplied weatherproof 4-line control handset keypad, with the computer’s electronic “brain” being housed in an independent portable external control box.

A PC is not required to operate the mount as GM mounts can be controlled using the supplied weatherproof 4-line control handset keypad, with the computer’s electronic “brain” being housed in an independent portable external control box.

The handset’s display and the large ergonomic keypad (ideal for when wearing gloves), features a red backlight for ease of use in the dark. An internal heater keeps the handset display warm when the mount is being used at low-temperatures which allows for maximum readability in all temperature and lighting conditions. The connectors of the motors, encoders, power and handset all use security lock screws for robust and secure connection.

Mount Control

If you wish to connect your own PC to control the mount, a WiFi, RS-232 or Ethernet connection is needed. The GM mounts can then be controlled using commonly available software packages via the proprietary 10Micron ASCOM driver (or Meade compatible command protocol). Included with the mount is software that creates a “virtual handset” on your PC with the same functionality and features as the physical hand set for easy (and familiar) control from your computer. Furthermore, the RS-232 port on the external can be utilised to control an observatory dome (and without a PC). The mount can also be parked in different user-defined positions in case of any internal “obstructions” and can also be switched on and off using the dedicated connector on the control box panel.  All these features help make the GM HPS mounts ideal for observatories and for remote operation.
