Important note:

GM 4000 HPS II GoTo-Mount

HPS stands for High Precision and Speed and the mount is an advancement of the known GM 2000 QCI of 10Micron with the same proven mechanics, however, less load-carrying capacity than this - and with it highly transportable

The GM 4000 HPS reaches a Satellite tracking and positioning speed from 5 degrees / sek. with an average positioning accuracy <20" and a tracking accuracy of approx. 1"/15min (peak to peak).

10Micron has modernized the well proven parallactic / equatorial mount. By "Dual Axis Tracking", small errors in the polar axis and other disturbing parameters, such as deflection of the telescope tube, are compensated fully automatically during tracking.

The GM 4000 HPS disposes, in addition, of high-precision Absolut-Encoders on both axes which opens absolutely new possibilities. The mount never loses its orientation, even if one axis is shifted by hand. Also after a power failure no new Alignment is necessary. 

Standard configuration of all HPS Mounts

  • 4-Lines Stand-Alone Keypad with metal housing and heated screen (#1452059)
  • embedded Computer-Controller with Linux Managment System for complete remote use of the mount incl. all functions such as satellite tracking, moon feature and more
  • Interface: RS232, Ethernet, (Wi-Fi not available in Cold Temp version)
  • Connectors for: GPS, Autoguider, Keypad, Mount, Aux and Remote Switch
  • Connection cables, counterweight bar
  • PC Software: Virtual Keypad, Clock Sync Tool, Multi Mount, ASCOM Driver
  • Instruction manual

ColdTemp-Upgrade for GM4000 mounts is included

Modification package for ext. temperature range to -30°C

Not available for retrofitting existing mounts

Standard cables and greases become brittle and cause severe premature aging when subjected to deep freeze temperatures over longer periods of time. We strongly advise to choose this upgrade package for either GM3000 or GM4000 mounts, in case the mechanics and electronics of the mount have to work flawlessly under hard environmental conditions. Please note that this can only be integrated into the mount during master assembly and can not be upgraded. This treatment would cost many times as much, if it were to be performed on an existing mount that would need to be fully disassembled to the core.

The ColdTemp-package includes:

  • Highest cost low temperature grease for bearings and worm gear (suitable viscosity stretched down to - 60°C)
  • Pre-tension springs on axes and shafts for thermal compensation
  • Integrated Linux PC w. extended XT range survival pack (up to -40°C/specified by the manufacturer)
  • All internal cabling replaced w. high endurance siliconflex cables (internal cable strands are being replaced by low temp copper alloy w. individual high strength silicone mantling)
  • Absolute encoders modified for -40°C continuous operation
  • Heavy duty test in cold chamber for several days

WiFi-Upgrade is not available in combination with the ColdTemp package!
