ZWO Harmonic Mounts

ZWO harmonic mounts use strain-wave gearing instead of a worm gear, which keeps the mount head light while carrying a heavy payload. They can run without a counterweight for many setups and are controlled from the ASIAIR app or ASCOM software.

The range includes the AM3N, AM5N and AM7 with TC40 tripod, Limited RedCat Editions of the AM3 and AM5N paired with a William Optics RedCat, and a counterweight bar for the AM5 when you need more payload.
