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 3.9kg, 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 with the counterweight.
  
• Supported counterweight: 5kg - The counterweight should be secured on a counterweight bar of no more than 25 cm in length.

Versatile:

• Equatorial Mode / Altazimuth Mode can be switched via ASI Mount App or hand controller.
  
• Equatorial Mode: Suitable for tracking and photographing objects
  
• Altazimuth Mode: Suitable for visual astronomy

All-round 0°-90° Pitch Angle:
Gear 1: Allow you to adjust the pitch angle grip to achieve a degree between 0 and 60.
Gear 2: You can loosen the hex-head screw and then adjust the pitch angle grip to achieve a degree between 30 and 90.

Rocker-style Hand Controller:
Comfortable touch and easy to use. Integrated with a Wi-Fi network allowing for wireless control. You can easily upgrade the firmware of the hand controller and mount on the ZWO webpage.
