The television multichannel spectrophotometer of the BTA (SAO, USSR AS), used for accumulating and recording the spectra of faint astronomical objects, is described. The Soviet image detection system comprises a three-stage image tube (UM-92) optically coupled to a high sensitivity SIT TV tube. The system operates in a photon counting mode with digital definition of the centres of photoelectron events. The spectrophotometer operates on-line with a minicomputer which exercises control of the system and performs primary reductions of the data collected. Illustrations of scans obtained during observations are given.
