ZWO AM3N Harmonic Mount

ZWO AM3 Harmonic Equatorial Mount – GoTo Travel Mount – Mount Head. The traditional equatorial mount requires heavy counterweights. It can be difficult to keep balance in RA and DEC directions, and can be also inconvenient for transit and storage.

To solve the above issues, ZWO developed the ASI Mount series. No need for a counterweight. With a self-weight of 4.1kg, AM3 has a large load capacity from 8kg to 13kg. While portability is very important, stability is also essential in use. The internal structure of the body is optimized with a strain wave gear reducer and synchronous belt, bringing more accurate control and an amazing reduction ratio of 300:1. It is also multi-functional and can be used as both an equatorial mount or an altazimuth mount. You can either control the mount via Wi-Fi, Bluetooth, or a hand controller.

Portable and stable:
The internal structure of the body is optimized with the strain wave gear reducer and synchronous belt, bringing more accurate control and an amazing reduction ratio of 300:1.

Customized Strain Wave Gear:
ZWO developed the special strain wave gear based on the actual needs for astrophotography. It comes with very low periodic error and high torque. Each mount is tested and equipped with an exclusive PE curve before it leaves the factory so that the quality can be guaranteed.

Payload capacity:

• The load capacity of AM3 without the counterweight is 8kg and 13kg (* 13kg when used with an ‚optional‘ counterweight.)
• Supported counterweight: 5kg – The counterweight should be secured on a counterweight bar of no more than 25 cm in length.

Integrated Type-C and DC Power Ports:

The newly optimized design also improves portability by effectively reducing the need for complex cable management. The dovetail saddle now integrates Type-C and 12 V DC ports to minimize clutter, while a magnetic hex key attaches directly to the mount for convenient storage.

All-round 0°-90° Pitch Angle:

The AM3N features a versatile altitude adjustment design ranging from 0° to 90°, allowing for unrestricted use across both low-and high-latitude regions.

Using Gear 1:

1. Turn the altitude fine adjustment knob for adjustment between 0° and 60°.

Setting Gear 2:

We recommend you do this when the AM3N is not carrying anything.

1. Loosen the tension grips on both sides.
2. Rotate the latitude fine adjustment knob clockwise until you can see the hex screws on AM3´s two sides with no obstruction (approximately 45° latitude at gear 1).
3. Loosen the M6 hex screws and adjust the mount to approximately 75°.
4. Tighten the hex screws again.
5. Tighten the tension grips on both sides again.

Using Gear 2:
 Turn the altitude fine adjustment knob for adjustment between 30° and 90°.

Evolved Portable Control – Wi-Fi & Bluetooth Connectivity:

The AM3N features built-in Wi-Fi and Bluetooth, enabling direct smartphone control – no hand controller is required. This makes it ideal for travel and field use – just bring your phone and you´re ready to observe or start imaging.

Wireless Control via Mobile Apps:

Operate the mount directly from your phone with an intuitive app featuring an ‚on-screen joystick‘, Tonight´s Target, GOTO, Live Preview, and much more. The mount is naturally also compatible with ASCOM, INDI, ASIAIR, and other platforms.

Rocker-style Hand Controller:

Comfortable touch and easy to use – Integrated with the Wi-Fi network allowing for wireless control. You can easily upgrade the firmware of the hand controller and mount using the Official ZWO website.

Seamless Linkage with ASIAIR:

Experience astrophotography at its best with the ZWO Ecosystem – where every component works together in perfect harmony. ASIAIR can control AM3 via a wired or wireless connection.
