Its strain wave gear system and stepper motors deliver a 0.17\" resolution for precise tracking, while the full 0° to 90° latitude range makes it operational from the equator to the poles. With a maximum capacity of 66 lb. using an optional counterweight, the AM7 supports large optical tubes for serious astrophotography.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e44 lb. Capacity from a 14.9 lb. Mount\u003c\/h3\u003e\n\u003cp\u003eThe core of the AM7's design is its strain wave gear and synchronous belt drive system, which achieves a high payload-to-weight ratio that conventional worm gear mounts cannot match. This allows you to carry up to 44 lb. of imaging equipment without the need for a counterweight, drastically reducing the total weight and complexity of your field setup. For heavier optical tubes, adding a counterweight to the included M16 bar increases the total capacity to 66 lb., putting large refractors and SCTs well within its capability.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eZWO AM7 vs. AM5: A 33% Payload Increase\u003c\/h3\u003e\n\u003cp\u003eFor imagers deciding between ZWO's harmonic mounts, the choice comes down to payload.

The conversion is purely mechanical, requiring no firmware changes. With an exceptionally wide latitude adjustment range of 0° to 90°, you can polar align the mount anywhere on Earth.
