Design & Performance Highlights

Lightweight & Powerful

Only 5 kg, yet supports up to 14 kg without counterweights thanks to its efficient strain-wave drive system.

High-Precision Strain-Wave Gears

Harmonic gears on both axes ensure high payload support and smooth, backlash-free tracking. The RA axis achieves 0.15″ resolution for sub-arcsecond tracking accuracy.

Supports High Imaging Loads

No counterweights needed up to 14 kg payload. Use the M12 DEC shaft for counterweights with heavier rigs.

Equatorial or Alt-Az Mode

Switch between German Equatorial and Alt-Az configurations via PC, hand controller or mobile app.

Power-Off Brake

A safety brake engages automatically on the RA axis during a power interruption.

Wireless & USB Operation

Simultaneous USB2 and Wi-Fi operation. Works with ASCOM/Alpaca, INDI, LX200 and SkySafari.
