Scientific paper

The PPKh-75 programmable field chronorecorder has been developed for star observations. Its basic functions are programmed control of the exposure shutter of the camera-attachment, determination of the time lag of the mechanical displacement of the exposure shutter, and digital time-indication during the comparison of the working scale to the reference scale. The device consists of two independent units a time-pulse generator and an electronic measurement unit.
