About this product

Model:  10micron_1452030
Part Number:  1452030

The 10Micron GM2000 HPS II German equatorial mount is the second largest in their German Equatorial mount range.

Though heavier than its smaller GM1000 brother, it is still a transportable, sturdy platform with the same Italian engineering, craftsmanship, build quality and features as its bigger brothers—a genuinely premium mount for astronomy and astrophotography.

With a weight of 33kg / 73lbs (mount head only), it is transportable yet can carry a total equipment payload of up to 50kg /110lbs, so an excellent choice for those wanting a mount for larger astronomical equipment.

Separable into Dec and RA axis for easy carrying and assembly. 

The mount separates into two components, weighing 18kg (40lbs) and 15kg (33lbs), making the GM2000 easier to transport and carry.

This 'Combi' mount is essentially a GM2000 HPS II Ultraport that can be separated into two parts and features an additional locking system. This new locking feature benefits those with the mount permanently installed in an observatory and ensures long-term stability, comparable to the previous GM2000 HPS II Monolith model. Splitting the mount is easy - simply remove the locking screws.

The benefits of the previous GM2000 models feature in this new GM2000 HPSII Combi mount, which replaces the previous Monolith and Ultraport models. The technical specifications, sizes and weight of the new GM2000 HPS II COMBI are the same as the GM2000 HPS II Ultraport.

 

 

HPS

All 10Micron GM mounts feature High Precision and Speed 'HPS'.  

Traditional worm and wheel gears combined with the latest state-of-the-art encoder technology enable these mounts to perform at the same level of precision as professional direct-drive mounts.

Two high-precision proprietary (1/10th arcsec resolution) 'absolute encoders' 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).

The diagram above shows the 10Micron GM mount RA tracking error profile measured with an encoder coupled to the RA axis. To show how accurate the tracking is, Jupiter and its moon Ganymede are shown as they appear from Earth at the same scale in arc seconds.

The high-speed slewing of the mount, from 2 degrees to sprightly 20 degrees per second, is achieved using high-performance servo motors.

Features

The GM2000’s Right Ascension and Declination axes, both made from 50mm 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 gear pairs. The worm wheels are made of (B14) bronze, with a diameter of 172mm and 215 teeth. Each worm is 24mm in diameter and made from alloy steel.

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

GM mounts can track 30 degrees/2 hours past the meridian, so long-duration astrophotography is easily achievable. 

The absolute encoders provide extremely high tracking accuracy (<1 arcsec), so autoguiding is unnecessary. However, GM mounts are compatible with an auto-guider via a standard ST4-compatible guide port if required.

Object Database

The built-in object database contains celestial objects from 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 needing 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” housed in an independent portable external control box.

The handset’s display and the large ergonomic keypad (cab be used while 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 used at low temperatures for maximum readability in all temperature and lighting conditions.

The connectors of the motors, encoders, power and handset all use security lock screws for a robust and secure connection.

Mount Control

If you wish to connect your 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 handset 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”. It 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 remote operation.
