Please note, the manufacturer have no package sizes and weights yet, therefore the price has been calculated by using an estimate for the packing sizes and estimated shipping costs and thus the sale price might need adjusting. Although we do not expect huge changes and hope that we won't have to change the price at all, we cannot absolutely guarantee it.

Traditional equatorial mounts require heavy counterweights for use. Extra effort needed to achieve balance in RA and DEC directions and the extra weight makes them not so convenient when there is a need to take the equipment away to a dark site or even just to the other end of the garden...

Well made harmonic drive mounts bring the solution. The internal structure of the body is optimised with the harmonic drive speed reducer and synchronous belt, bringing more accurate control and an amazing reduction ratio of 300:1.

Astronomy-dedicated Harmonic Speed Reducer

ZWO jointly developed with well-known domestic manufacturers to improve the harmonic drive speed reducer according to the actual needs of astro-photography.

It comes with very low periodic errors, smooth gearing and high torque. The guiding accuracy is 0.5-0.8 arc seconds, which makes the AM5 mount extremely suitable for astrophotography.

The internal structure of the body is optimised with the harmonic drive speed reducer and synchronous belt, bringing more accurate control and an amazing reduction ratio of 300:1.

PE Curve Report with Each Mount
ZWO measures each mount and provides it with an exclusive PE curve before it leaves the factory. The x-axis represents the periodic error. The periodic erro is kept within +/- 20 arc seconds.

Lightweight Mount with High Load Capacity
The mount weights 5 kg, which is a very good compromise between stability and portability.

Load capacity without a counterweight is 13kg.

The mount also comes with a counterweight, and when you use it, the load capacity increases to appr. 20kg.

The design of the mount makes it possible to change the pitch angle between 0 and 90 degrees, which also allows to convert the mount from equatorial into an Alt-Azimuth mount for convenient visual observations with your telescope.
