ZWO AM3 Harmonic Drive Equatorial Mount Head

Product Description

Traditional equatorial mounts require counterweights, and maintaining balance in RA and DEC directions can be difficult. Their size andshape can also make them inconvenient for transit and storage. Some strain wave geared mounts are relatively simple in function, insufficient in load capacity, and not very stable in use.

To solve the above issues, ZWO developed their ASI Mount series. With a body weight of only 3.9kg, the AM3 has a large load capacity from 8kg (without counterweight) to 13kg (with counterweight). Portability is important, but so too, is stability. Instead of pursuing only the lightest mount body weight, ZWO has paid careful attention to stability and ease of use. The body's internal structure is optimised for the strain wave gear reducer and synchronous belt, bringing more accurate control and an amazing reduction ratio of 300:1.

The AM3 can be used as an equatorial or altazimuth mount and controlled via Wi-Fi, Bluetooth, or a hand controller.

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.

3.9kg Net Weight
Instead of blindly pursuing the lightweight of the mount body, ZWO is more so along the lines of stability for an entire use.

8kg-13kg payload
The load capacity of AM3 without the counterweight is 8kg, and 13kg with the counterweight.

* The counterweight should be secured on a counterweight bar of no more than 20cm in length.

According to the engineering calculations, we can calculate the maximum load capacity of the AM3 mount:

8kg without the counterweight

13kg with the counterweight.

Supported counterweight:=5kg

The counterweight should be secured on a counterweight bar of no more than 25cm in length.

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 angel grip to achieve a degree between 30 and 90.

Wireless Control
Tonight’s Target, GOTO, Live Preview and so many great functions can all be achieved with your phones.

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

Seamless Linkage with ASIAIR
ASIAIR can control AM5 via a wired or wireless connection. The ASI package gives customers the best astrophotography experience.
