10Micron GM4000 HPS II is a German equatorial GoTo mount rated for 150 kg of instrumentation. The mount weighs 125 kg without accessories and uses absolute encoders mounted directly on the axes, brushless servo motors and a precision worm drive.
Drive and mechanical construction
The published slew range is 2–8°/s. Its mechanical system uses 60 mm stainless-steel counterweight-shaft hardware, preloaded bearings and timing-belt reduction with automatic backlash recovery.
Pointing and tracking
The internal pointing model supports up to 100 alignment points and compensation for polar alignment, orthogonality, atmospheric refraction and system flexure. Manufacturer tracking examples refer to a modelled system; telescope rigidity, model quality and observing conditions still affect results.
Control and power
A heated, dimmable keypad provides standalone operation. Ethernet, Wi-Fi/web control and RS-232 support remote workflows, with separate GPS and ST-4 interfaces. The mount uses 24 V DC; power-supply and receiver connections must match the control-box generation.
Configuration and equipment
The native equatorial layout is intended for imaging and observing within the published latitude and meridian limits. Counterweights are sold separately. The technical table lists the standard package and separates operating temperature from storage limits.
The current GM4000 technical sheet specifies 4 A maximum-slew and 5 A peak; older brochures give 5 A and 6 A. Current model technical-sheet values are selected. Its 60 mm internal cable passage is distinct from its 60 mm counterweight shaft.
