ZWO AM7 Harmonic Equatorial Mount

The ZWO AM7 Harmonic Equatorial Mount is a high-performance solution for astrophotographers seeking precision tracking, high payload capacity, and a compact, portable design. Engineered with advanced harmonic drive technology, the AM7 is built to support larger imaging systems and longer focal lengths, making it a mount you can grow into over time.

High Payload Capacity Without Compromise

The AM7 supports up to 20 kg of payload without counterweights, allowing for clean and streamlined imaging setups. When counterweights are added, total capacity increases to 30 kg, giving you the flexibility to run heavier telescopes, cameras, and accessories with confidence.

Verified Tracking Accuracy

Each ZWO AM7 mount is individually tested and supplied with its own periodic error (PE) report. Tracking accuracy is maintained within ±10 arcseconds, delivering reliable performance for long-exposure astrophotography and consistent guiding results.

Advanced Harmonic Drive Technology

The custom ZWO harmonic drive system features a 300:1 total gear reduction, providing high torque, smooth motion, and stable tracking. This design minimizes backlash and improves accuracy under real-world imaging loads.

Integrated Cable Management

Built-in USB-C and DC power ports located in the dovetail saddle allow power and data cables to be routed directly through the mount. This reduces cable clutter, improves balance, and speeds up setup—ideal for automated and remote imaging rigs.

Dual Operating Modes

The AM7 supports both equatorial and alt-azimuth operation, offering flexibility for imaging and visual observing.

Equatorial Mode – Precision tracking for astrophotography

Alt-Az Mode – Fast and convenient setup for visual use

Clear LED indicators display the active mode at a glance.

Worldwide Latitude Compatibility

With a 0–90° altitude adjustment range, the AM7 can be used anywhere on Earth, from equatorial regions to polar locations. This makes it an excellent choice for travel, mobile setups, or permanent observatories.

Lightweight and Portable Design

Despite its impressive payload capacity, the AM7 weighs approximately 6.7 kg, making it easy to transport while remaining exceptionally rigid and stable during operation.

Flexible Control Options

The mount can be controlled via the included ergonomic hand controller, Bluetooth, or Wi-Fi. Bluetooth functionality can be enabled or disabled as needed, offering flexibility for both field use and observatory installations.

Smart Hand Controller & Wireless Hub

The joystick-style hand controller also functions as the system’s wireless hub, allowing firmware updates, configuration changes, and wireless control. Softened LED indicators help preserve night vision during imaging sessions.

ASIAIR Ready

As part of the ZWO ecosystem, the AM7 integrates seamlessly with ASIAIR controllers via wired or wireless connections. This ensures simplified setup, excellent compatibility, and continued feature support through software updates.

Built for All Conditions

The ZWO AM7 is rated for operation down to -20°C, ensuring dependable performance even during cold-weather imaging sessions.

A Long-Term Imaging Solution

Combining high payload capacity, verified precision, and modern harmonic drive technology, the ZWO AM7 is a future-proof mount for serious astrophotographers. Whether you are running a compact setup today or planning a more advanced system in the future, the AM7 delivers accuracy, reliability, and flexibility in a portable design.
