Pairing an apochromatic reflector with a precise and compact harmonic mount, this FF80mm APO Telescope & AM3N Strain Wave Gear Mount Kit from B&H sets you up for both astrophotography and observation. The f/7.5 telescope provides a flat field with no need for a corrector and the mount's strain wave gearing allows it to handle photo gear with no counterweight. Add an appropriate tripod or pier and you're ready to see and share the wonders of the night sky.
Providing smooth strain wave gearing and neat cable management, the ZWO AM3N Strain Wave Gear Mount offers altazimuth operation for observation and go-to equatorial tracking via an app or a hand controller for astrophotography. The mount weighs just nine pounds but can support up to 17.6 pounds on its own or 28.7 pounds with a user-supplied counterweight and shaft. The brake system prevents the mount from toppling if the power is cut off. The mount runs on a user-supplied 12V, 3A power supply and is compatible with ASCOM and ZWO's ASIAIR platforms.
- Weighs 9 pounds
- Supports 17.6 pounds without counterweight
- Supports 28.7 pounds with optional counterweight
- Strain-wave gearing system comes with very low periodic errors, smooth gearing, and high torque
- Reduction ratio is 300:1
- Each mount is tested and shipped with a periodic error curve report
- Capable of both equatorial and altazimuth modes
- Suitable for both visual and imaging
- Elevation angle of 0-90°
- Can be used anywhere from the equator to the polar regions
- Red light is displayed for equatorial mount mode
- Green light is displayed for alt-azimuth mode
- If the mount has no synchronization, the indicator light flashes alternately red and green, and the corresponding color indicator light will be displayed according to the mode after synchronization
- Control via the included hand controller or from your phone or tablet using the AM5 app
- App offers onscreen joystick and convenient tools including Best Objects of the Evening and a built-in star map with real-time display and GoTo functions
- There is no need to connect to a computer—the mount and hand controller connect via Wi-Fi
- The mount is compatible with ASCOM, INDI, ASIAIR, and other platforms
- In the event of power failure, brakes are instantly applied to prevent damage to the telescope and equipment from falling
Designed for astrophotography but also great for observation, the FF80 APO Astronomical Telescope from ZWO features a quadruplet air-spaced apochromatic lens system that eliminates the need to use a separate field flattener. The quad APO with two extra-low dispersion elements also dramatically reduces chromatic aberration and eliminates the need to calculate back focus distance—just attach your camera with one of the four included adapters and you're ready for imaging. The f/7.5 focal ratio and 600mm focal length lend themselves to both planetary and deep-sky photography. An optional diagonal and eyepieces are required for visual use.
- f/7.5 focal ratio and 600mm focal length allow for both deep-sky and planetary imaging
- Quadruplet air-spaced apochromatic refractor design with two ED elements produces rich views with minimal chromatic aberration
- Quad APO is self-flattening, eliminating the need for a separate field flattener
- Supports 44mm image circle for full-frame cameras
- Fine spot diagram with tiny distortion of peripheral stars and under-3µ central RMS radius
- Sturdy 3" rack-and-pinion design can easily carry larger and heavier eyepieces, accessories like Barlows and focal reducers, and imaging systems
- 360° rotator with scales and finder base
- 10:1 fine adjustment ratio
- Anodized red handle and tube ring assembly, can be detached and reinstalled in seconds
- Handle has M6 screw holes for attaching accessories
- M76, M68, M54, and M48 camera adapters
