ZWO AM3 Equatorial Mount with Harmonic Drive Gears
ZWO offers a portable mount for astrophotography with the Harmonic Equatorial Mount AM3N. The mount weighs less than 4 kg and supports telescopes up to 8 kg without a counterweight. With a counterweight and the counterweight rod (not included), the mount can even support telescopes up to 13 kg. Several years of development and various patents have gone into this exciting mount. The periodic error is less than 15 arcseconds.

Many functions and easy operation
The AM3N can be operated in equatorial and azimuthal modes. For astrophotography, the equatorial/equatorial mode is used. The mount must be aligned as precisely as possible to the celestial pole. For visual observation or lunar and planetary photography, the azimuthal mode is sufficient. The mount is then ready for use in just a few minutes. The status indicator always indicates which mode the mount is in: red indicates equatorial mode, green indicates azimuthal mode.

Counterweights are no longer required
German mounts usually require counterweights to balance the telescope weight. This is the only way to ensure proper function. The AM3N uses an industry-standard wave gear. Therefore, it does not require counterweights for telescopes up to 8 kg. This makes the AM3N lighter, more compact, and easier to operate. We only recommend counterweights for heavier telescopes to keep the mount and tripod balanced. Counterweight rod connection thread: M12 x 1.75

Smooth tracking is guaranteed
ZWO tests and measures every AM3N mount before delivery and guarantees a periodic error (PE) of less than +/-15 arcseconds. The periodic error occurs very slowly, giving the autoguider sufficient time to correct itself. The mount naturally features an ST-4 autoguiding interface. The PE can also be reduced electronically using ASIAir or other software.

Can be used anywhere on earth
As you would expect from a true travel mount, the AM3 can be used anywhere on earth, from the equator to the poles. The mount fits in any airline luggage.

No more cables thanks to Wi-Fi
All mount functions can be controlled via smartphone. The AM3N works particularly well with ZWO's ASIAir. With ASIAIR, everything from the camera to the autoguiding to the mount can be controlled via an app on a smartphone or tablet. The mount can also be operated with the handheld controller without a smartphone. The handheld controller is also wireless.

N is for New:

Improved cable management: Like the AM5N, the AM3N now features additional power ports and a USB Type-C port directly on the mount saddle.
The azimuth adjustment knob now features a tool-friendly hex wrench opening, allowing for easier adjustment of the mount.
The hex wrench holder is now magnetic, ensuring the tool stays securely in place.
Slight weight increase: Due to structural improvements, the weight has increased from 3.9 kg to 4.1 kg.
Updated power consumption: To improve load stability, the current consumption has been adjusted as follows: 1. Tracking mode: 12 V / 0.7 A 2. Goto mode: 12 V / 1.3 A (up to 1.8 A under heavy load)
Wider operating temperature range: The operating temperature range has been expanded to -20°C to 40°C, enabling better performance in cold environments.

Our expert comment:

The AM3 can support a maximum load of 8 kg without an additional counterweight. With a counterweight (5 kg), the load capacity is up to 13 kg. The optional counterweight must not exceed 5 kg in weight and should be attached with a counterweight rod no longer than 20 cm.
