Product details
The traditional equatorial mount requires heavy counterweights for use. It’s normally very difficult to keep balance in RA and DEC directions, also inconvenient for transit and storage, which bring the astronomy amateurs a lot of pain when they are out for imaging.
Some of the harmonic drive mounts are relatively simple in functions, insufficient in load capacity, also not very stable in use.
Mount Body
The internal structure of the body is optimized with the harmonic drive speed reducer and synchronous belt, bringing more accurate control and an amazing reduction ratio of 300:1.
Astronomy-Dedicated Harmonic Drive Speed Reducer
ZWO jointly developed with well-known domestic manufacturers to improve the harmonic drive speed reducer according to the actual needs of astrophotography. It comes with very low periodic errors, smooth gearing and high torque. The AM5 is born for astronomy.
ZWO measures each mount and equip it with the exclusive PE curve before it leaves our factory. The X-axis represent drive angle. Y-axis represents periodic errors. The periodic error is stably controlled within±20 arc-seconds.
5kg Mount Weight, Large Load Capacity
While portability is very important, stability is also essential in use. We don’t blindly pursue the lightweight of the mount body; we are more so along the lines of stability for entire use.
Load Capacity: 13kg – 20kg
The capacity without the counterweight attached is 13kg, 20kg with counterweight.
