80 mm APO Astrograph
The 80 mm apochromatic astrograph refractor from ZWO features a 4-element, 3+1 air-spaced quadruplet lens design, with two lenses made of extra-low dispersion (ED) glass to minimize chromatic and other aberrations. With an 80 mm aperture and a 600 mm focal length, this system produces a focal ratio of f/7.5. Its self-flattening design provides a flat field for imaging without the need for an additional field flattener accessory. Included are four camera adapters (sized M48, M54, M68, and M76) that allow for connecting a variety of cameras and accessories. M48 adapter also has an internal female thread for attaching 2″ filters. Also included is a 360-degree rotator, which allows for rotating an attached camera or accessory to the user’s desired orientation. The large 3″ dual-speed, rack-and-pinion focuser provides 1:10 fine adjustment. Finally, the 44 mm image circle supports full-frame camera sensors, offering a larger field of view.

AM3 Harmonic Drive EQ Mount
The internal structure of the AM3 Harmonic Drive EQ Mount is optimized with the strain wave gear reducer and synchronous belt. This optimization brings more accurate control and a fantastic reduction ratio of 300:1. The incorporated Harmonic drive speed reducer and synchronous belt allow this mount head to have precision control. While a traditional equatorial mount requires counterweights for use, this ZWO mount’s harmonic drive speed reducer and synchronous belt eliminate the need for counterweights, though they can be added if desired (an M12 thread interface is available for compatible, user-supplied counterweight shafts). In addition to having a large load capacity without needing counterweights, the AM3 mount is considered multi-functional and can be used as both an equatorial and alt-azimuth mount. The equatorial mode is great for tracking and imaging celestial objects while the alt-azimuth mode works well for observations. To add to its versatility, the AM3 can be controlled using either the included hand controller or WiFi/Bluetooth.

Carbon Fiber Tripod
Weighing in at 5 lb., this tripod is portable and still maintains a high load capacity of 110 lb. ZWO has machined TC40 this tripod from a carbon fiber material, increasing durability, strength, and impact resistance. The upper part of the tripod legs measures 1.5″ in diameter and the lower section measures 1.4″. The dual-section design provides better stability and rigidity when telescopes and cameras are mounted on the AM3 mount head. The tripod plate head comes with an adapter plate that has three mounting points that match the ZWO AM3 mount head. This ensures that the connection will be very stable and sturdy. Additionally, there is a center 3/8″ locking knob that has a range of compatibility. For the ZWO AM5 or AM3 mount head, you can keep it standard. For other mounts, you can keep it upside down and secure it with a 3/8″ tapped hole. The secure lock reinforces the connection between the mount and the tripod.
