A novel control device based on the integrated circuits of Series К155 and KR556 generates commands for starting the carriage driving motor, opening the shutter, and rotating the photographic zenith tube through 180°. The time of commencement of observation cycles and the types of cycles for 256 stars are programmed in the device. The exposure times are set automatically, depending on the type of the cycle. The device simplifies the work of the observer and helps increase the accuracy of determining the latitude and clock correction.
