ZWO AM7 HARMONIC EQUATORIAL MOUNT
The ZWO AM7 is a high capacity strain wave-geared equatorial/alt-az mount for on the go visual observing and astrophotography, with an increased payload of 20kg without counterweights and 30kg with counterweights.
Like the AM3N & AM5N, the AM7 has excellent tracking performance with small periodic error (typically >± 10 arcsec) and includes power and USB output for mount control on the saddle, making cable management easier.
Incredibly lightweight at only 6.75kg, the AM7 has an impressive payload of 20kg without counterweight or 30kg with counterweight. Despite its size, the AM7 is precisely engineered to be stable and sturdy enough for deep sky imaging with a wide range of telescopes.
With a latitude range of 0-90°, the mount can be used easily near the equator. An increased azimuth adjustment range of ± 7.5º allows for more convenient polar alignment, particularly when mounted on a permanent pier that can't easily be rotated.
The AM7 can be controlled via Wi-Fi, Bluetooth or a wired USB connection seamlessly with the ASIAIR or ASCOM/INDI with the LX200 command set, as well as with the included hand controller. You can also use the AM7 app to control the mount over Wi-Fi or Bluetooth with a smartphone/tablet.
ZWO has developed custom harmonic drive speed reducer with the demands of imaging in mind. This along with the mount's synchronous belt transmission system results in high torque, smooth gearing and very low periodic error make the AM7 an excellent mount for astrophotography.
The mount is equipped with an electromagnetic brake on the RA axis in case of sudden power failure, which will prevent your telescope from being damaged.
The hollow-knob ergonomic design of the dovetail saddle tension knobs and azimuth fine-tuning knobs have slots for inserting a hex wrench for extra leverage, making adjustment easier with less effort.
The AM7 includes the B250 counterweight bar with an M16 thread. The bar is compatible with counterweights which have an internal bore size of 25mm. The AM5N can be connected to any tripod that has a 3/8" bolt in the centre.
- Geoptik 5kg counterweight for Geoptik 25mm Bar
- Geoptik 10kg counterweight for Geoptik 25mm Bar
- Sky-Watcher AZ-EQ6 counterweight
