Two digital television complexes with three small telescopes have been successfully used for photometric and spectrophotometric observations at the Crimean astrophysical observatory. All data have absolute calibration, recorded to a personal computer and reduced for flat field and distortion. The high sensitive pickup tube I-isocon of the first complex has mounted at the 500-mm meniscus telescope. The second tube coupled to the 200-mm telescope used as a television guide. The second complex can be used with 380-mm telescope. Two TV complexes can work simultaneously observing one object or different objects. The complex is equipped with filters reproduced photometric B, V, R bands and two spectrographs. The BVR observations of stars with magnitudes up to 19^m are carried out with the accuracy of 0.05^m with exposure time about several minutes. Simultaneous observations in the BVR bands can be carried out also. The original afocal slitless spectrograph allows us to receive the absolute spectral distribution in spectra of point sources up to 14^m with spectral resolution about 50 angstrom and exposure time of several minutes. The slit spectrograph allowed us to receive unique Jupiter observations during its collision with comet Shoemaker-Levy 9.
