A short description of the computer controlled guiding system using im
ages from a sensitive TV camera is presented. The system works with a
0.6/7.5 m telescope of Mt. Suhora Observatory and can accept input fro
m any standard video camera. The IBM 286-486 or compatible personal co
mputer equipped with a SVGA graphic card and framegrabber card is used
as a control unit. The program works under a DOS operating system. An
effect of guiding on the classic photoelectric photometry and CCD ima
ge quality is discussed.
