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.Optical Tube Assembly f/7.5 focal ratio and 600mm focal length allow for both deep-sky and planetary imagingQuadruplet air-spaced apochromatic refractor design with two ED elements produces rich views with minimal chromatic aberrationQuad APO is self-flattening, eliminating the need for a separate field flattenerSupports 44mm image circle for full-frame camerasFine spot diagram with tiny distortion of peripheral stars and under-3 central RMS radiusFocuser Sturdy 3" rack-and-pinion design can easily carry larger and heavier eyepieces, accessories like Barlows and focal reducers, and imaging systems360 rotator with scales and finder base10:1 fine adjustment ratioUse and Handling Anodized red handle and tube ring assembly, can be detached and reinstalled in secondsHandle has M6 screw holes for attaching accessoriesM76, M68, M54, and M48 camera adapters
