  • ZWO AM7 Harmonic Equatorial Mount - Overview

    The ZWO AM7 Harmonic Equatorial Mount is ZWO’s highest-capacity harmonic drive mount, engineered for heavier imaging systems and long focal length astrophotography where tracking accuracy and mechanical stability are critical.

    ZWO AM7 Harmonic Equatorial Mount - High Load Capacity

    High Load Capacity

    Without counterweight: 20kg

    With counterweight: 30kg

    Designed to support larger optical tubes, long focal length refractors, and fully equipped imaging trains.

    Cable Management

    Integrated USB Type-C and DC power ports on the dovetail saddle allow power and data to be routed cleanly through the mount, reducing cable drag and improving reliability during long tracking sessions.

    ZWO AM7 Harmonic Equatorial Mount - Precision Control

    Precision Control

    Custom harmonic drive system with periodic error controlled within ±10 arcseconds

    300:1 reduction ratio provides high torque output and smooth, consistent tracking

    Each AM7 includes an individual periodic error test report for verification.

    Wireless Control

    Supports Wi-Fi, Bluetooth, and the included smart hand controller for flexible operation.

    Compatible with Sky Atlas and ASIAIR for GoTo, object databases, live star maps, and firmware updates.
