A twin-beam multiband photoelectric photometer has been constructed for ground-based astronomical observations. The photometer is integrated to a computer to obtain a high degree of flexibility and efficiency. The structure minimizes the atmospheric transmittance variations. It uses the photon-counting technique to optimize the SNR. Constraints on the precision of astronomical photoelectric photometry are discussed. The philosophy, structure, and possible extensions of the photometer are described. The results of a test on the dynamic behavior of the whole system are also given. This photometer is more flexible, more reliable, and simpler than other similar ones.
