HATNet (Hungarian Automated Telescope Network) is a set of automated (robotic) telescopes to search for Transiting Planets. HAT-1, in operation since 2001, at Konkoly Observatory in Budapest, was designed with a 512 x 768 CCD, later upgraded to a 65mm Aperture telescope with a Field of View (FOV) of 8 degrees by 8 degrees, with a 2k x 2k CCD.
HAT-South is three telescopes at this time, in Australia, Namibia, and Chile. In 2017, 29 Extra Solar Planet discoveries are credited to them.
