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.

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.

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.

Dual Mount Functionality

Operates as both an Equatorial Mount for imaging and an Alt-Azimuth Mount for visual observing, with a full altitude adjustment range of 0–90°.

Portable High-Capacity Design

Mount weight: approximately 6.5–6.75kg, balancing portability with the strength required for heavier payloads.

Cold Weather Performance

Rated for reliable operation down to -20°C, ensuring consistent performance during winter imaging sessions.

Power-Off Protection

Integrated RA-axis brake prevents uncontrolled movement in the event of power loss, protecting mounted equipment.
Astronomy-Dedicated Harmonic Drive

Purpose-built for astrophotography applications, delivering:
- Low and consistent periodic error
- High torque under real imaging loads
- Stable transmission for long focal length systems
All-Round 0–90° Latitude Adjustment

Primary adjustment range of 0–60° using the altitude adjustment knob

Secondary adjustment up to 90° enabled by repositioning the hex-head screw

Why Choose the ZWO AM7?

Higher Payload Capacity: Designed for heavier and longer optical systems

Verified Precision: Individual periodic error testing included

Cleaner Setup: Integrated power and data routing

Scalable Platform: A mount you can grow into as your equipment evolves
