Designed for astrophotography but also great for observation, the ZWO FF80 APO Telescope OTA | Astronomical Opticsfrom ZWO FF80 APO Telescope OTA | Astronomical Opticsfeatures 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.
