The ZWO FF80 is an astrograph designed for wide-field deep sky astronomical imaging. Its optical system consists of a quadruplet (4 lenses) including a field flattener providing a corrected image circle of 44 mm in diameter, covering full-frame sensors. The FF80 is equipped for imaging with its oversized (76 mm) focuser system with reduction gear, easily motorized, and its numerous photographic adapters. Its main advantage is the ease of mounting cameras and photographic devices at the focal plane. There is no need to worry about backfocus; just screw in your accessories and that’s it!
