Kraus-type
The Kraus-type radio telescope design was created by Dr. John D. Kraus (1910–2004). Kraus-type telescopes are transit instruments, where the flat primary reflects radio light towards the spherical secondary, which focuses it towards a mobile focal carriage. The primary tilts North-South to select any object near the meridian, while the focal carriage moves East-West along railroad ties to track objects near transit. The following telescopes are Kraus-type. * Nançay Radio Telescope * The Big Ear
