Kraus-type radio telescope (original) (raw)

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 mirror reflects radio waves towards the spherical secondary mirror, 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.
