The CCD/Transit Instrument (CTI) is a unique, fully-automated imaging survey telesope now in routine operation on Kitt Peak Mountain. This telescope, which has no moving parts, uses two charge-coupled devices (CCDs) aligned east-west in the focal plane. The CCDs are operated in the time-delay and integrate (TDI) mode at the apparent sidereal rate to produce a strip image of the sky 8.25 arcminutes wide in declination and eight hours of time in length. In this way, about 15 square degrees of the sky are surveyed every clear night. Both the real-time acquisition computer system and the reduction, analysis and archival computer systems are described. The role of the CTI as a prototype for future specialized, low-cost telescopes is discussed. Implications for successfully handling the vast amount of data produced by CTI for future large telescope data systems are reviewed.
