ZWO AM7 Harmonic Equatorial Mount Head (No Tripod)

Load Capacity

The AM7 supports up to 20 kg without counterweights, and up to 30 kg with counterweights installed. That gives you room to run a serious setup now and still scale up later.

Tracking and GoTo

The goal is simple. Solid tracking and reliable GoTo under real payload, so you spend less time managing limits and more time imaging and exploring the night sky.

A Mount for the Long Haul

The AM7 handles both small and heavy setups, so you can grow into bigger telescopes without outgrowing your mount.

*Weights are manually measured and may vary slightly.

Professional Grade Precision With a Custom Harmonic Drive Mount

Built out of years of ZWO development and tuned for astrophotography, the AM7’s custom harmonic drive is designed for smooth, stable tracking with strong torque and consistent performance.

Every AM7 is individually tested before it ships. You get a unique periodic error curve report for your mount, so you can see the measured tracking performance of the exact unit you own.
