10Micron GM3000 HPS ColdTemp

10Micron GM3000 HPS ColdTemp combines the 100 kg instrument capacity of the standard mount with the manufacturer’s special low-temperature configuration. It is a German equatorial HPS mount with absolute on-axis encoders, precision worm gearing and two-axis brushless servo drive.

Cold-temperature equipment

10Micron specifies operation down to −30 °C for this option, using special low-temperature lubricants, silicone-sheathed wiring and suitable electronics. This is an operating specification for the ColdTemp build, not the much lower storage-temperature figure. It does not certify every attached camera, cable or third-party accessory for the same conditions.

Mechanics and performance

The model retains the standard mechanical architecture, 65 kg mount weight without accessories, 50 mm counterweight shaft and 2–12°/s published slewing range. The onboard model supports up to 100 points and compensates polar, orthogonality, refraction and flexure errors.

Control and installation

The 24 V DC system supports keypad and compatible remote computer/web control. Counterweights are separate. Match the power supply and GPS receiver to the actual control-box generation, and use the model-specific technical sheet and support interface for installation.

10Micron model technical sheet

Compatibility notes

Current model technical sheet and full catalogue specify 100 kg payload and a 12°/s maximum slew. A short product summary says 65 kg (the mount weight), while another paragraph says 20°/s; these contradictory prose figures are not used. The product-page Cold Temperature option explicitly states −30 °C; the technical-sheet “−30/−35” wording is not treated as an unconditional −35 °C guarantee.
