ZWO AM5
The ZWO AM5 is a strain-wave telescope mount with equatorial and alt-azimuth operating modes. The manufacturer-linked manual specifies a 5.5 kg mount body and payload up to 15 kg without a counterweight, or 20 kg with a counterweight, at the stated 25 cm reference lever arm.
Drive and pointing
The linked manufacturer manual lists strain-wave reduction with a synchronous belt, 300:1 total reduction, periodic error within ±10 arcseconds and a 288-second error period. Its RA-axis power-off brake provides protection if power is interrupted.
Mounting and adjustment
The saddle accepts Vixen and Losmandy profiles. Latitude adjustment covers 0–90° and azimuth adjustment ±6°. The counterweight-bar thread is M12 × 1.75; counterweight configuration and telescope centre of gravity must follow the manual.
Power and control
Use 12 V DC at a minimum of 3 A through a 5.5 × 2.1 mm centre-positive connector. The manual lists USB, Wi-Fi, Bluetooth and an ST4 guide port, with −20 to 40 °C operating temperature.
