ZWO AM3 Harmonic Drive Mount

The ZWO AM3 Harmonic Drive Mount is part of the ASI Mount series offering a new, ultra-portable and lightweight telescope mount utilizing harmonic drive technology. It is available with or without a matching carbon fiber tripod. It offers very low periodic error and high torque, and each mount is tested and equipped with an exclusive PE curve before it leaves the factory so that the quality can be guaranteed.

ZWO AM3 Harmonic Drive MountThe internal structure of the body is optimized with a strain wave gear reducer and synchronous belt, bringing accurate control and a reduction ratio of 300:1. The mount can carry 8 kg (17.6 lbs) without counterweights with a guiding accuracy of 0.5 – 0.8″ arcseconds and low periodic error. The mount head weighs 3.9 kg (8.6 lbs) and its payload can be increased to carry up to 13 kg (28.6 lbs) with counterweights.

The ZWO AM3 Harmonic Drive Mount is a hybrid mount and can operate in both equatorial and alt-azimuth modes. You can switch the mode through the included hand controller or through the available app. The body of the mount comes with a status light indicator that will indicate whether the mount is in an equatorial or alt-azimuth mode.

The ZWO AM3 mount can be controlled through the included rocker style hand controller or by using a WiFi connection from a smartphone or tablet. For wireless control, users can utilize the integrated WiFi network emitted by the hand controller and use Tonight’s Target, GoTo, Live Preview, and others to pair with the ZWO AM3 mount. The mount is also optimized to integrate with the ZWO ASIAIR.

The ZWO AM3 Harmonic Drive Mount is equipped with a power brake system. If there is a sudden power failure during use, the AM3 mount power failure protection design will prevent the telescope from falling and being damaged.

The available carbon fiber mount is short and portable making it easy to transport inside hand luggage. The Carbon fiber material offers high strength and high impact resistance with an adjustable height of 470-800mm. The dual-section legs provide a stable and rigid platform for telescopes and cameras and the spreader plate increases the stability of the tripod.
