I wish to present some aspects of a computer controlled pulse counting system for general photoelectric photometry.

The pulse counting technique applied in astronomical photoelectric photometry has yielded significant improvements as to telescope efficiency, especially in connection with the measurement of very faint light sources. This is achieved through the advantages inherent in the pulse counting technique over the conventional charge technique, that is:
