The ZWO AM7 Harmonic Equatorial Mount is a high-capacity, precision mount designed for advanced astrophotography and demanding visual observing. It combines a compact harmonic-drive architecture with high torque and rigidity, allowing it to support heavier imaging systems without the bulk of traditional counterweight-heavy mounts.

Positioned above the AM5 in ZWO’s mount lineup, the AM7 is aimed at users running larger telescopes, longer focal lengths, or full imaging trains where stability and balance margin are critical.

High Payload Capacity With or Without Counterweights

The AM7 supports up to 20 kg without counterweights, making it suitable for portable imaging setups, or up to 30 kg with counterweights installed for heavier telescopes and permanent or semi-permanent installations.

This flexibility allows users to adapt the mount to different observing styles without needing to change platforms.

Verified Precision Harmonic Drive System

At the core of the AM7 is a custom ZWO harmonic drive system with a total reduction ratio of 300:1. Each mount is individually tested before shipping and supplied with its own measured periodic error report.

Periodic error is controlled to within ±10 arcseconds, providing reliable tracking performance for guided imaging and enabling stable unguided performance in appropriate configurations.

Dual Mode Operation: Equatorial and Alt-Azimuth

The AM7 supports both Equatorial and Alt-Azimuth operation in a single mount:

• Equatorial Mode: Designed for accurate sidereal tracking during astrophotography and long-exposure imaging.
• Alt-Azimuth Mode: Enables fast setup and intuitive use for visual observing sessions.

A full 0–90° altitude adjustment range allows operation at any latitude worldwide.

Integrated Power and Clean Cable Management

Power and data ports are integrated directly into the dovetail saddle, allowing cables to be routed through the mount body. This reduces cable drag and simplifies complex imaging setups, particularly when using cameras, filter wheels, and electronic focusers.

A magnetic hex wrench stores directly on the mount, ensuring adjustment tools are always available during setup or polar alignment.

Portable Yet Exceptionally Rigid

Despite its high load capacity, the AM7 mount head weighs approximately 6.7 kg. This makes it manageable for transport while still offering the rigidity required for larger optical tubes and longer focal lengths.

Reliable Control and Connectivity

The AM7 can be controlled via Wi-Fi, Bluetooth, or the included smart hand controller. Bluetooth allows fast direct control from a smartphone, while Wi-Fi supports more advanced networked imaging setups.

AM7 Smart Hand Controller

The joystick-style hand controller also functions as a wireless hub, allowing firmware updates and configuration through a simple web interface. Bluetooth can be enabled or disabled depending on field or observatory requirements.

Seamless Integration With ASIAIR

As part of the ZWO ecosystem, the AM7 integrates seamlessly with ASIAIR controllers via wired or wireless connections. Station mode enables clean network integration without direct control cables.

Designed for Long-Term Reliability

Rated for operation down to −20 °C, the AM7 is engineered for demanding conditions and long-term use. It is widely adopted by astrophotographers running complex imaging systems and is supported by an active global user community.

Payload figures are based on manufacturer testing and simulation data. Actual performance depends on telescope balance, focal length, and environmental conditions.
