Аннотация:The development of a four-channel photoelectric photometer for WBVR observations of bright stars is described. The principal feature of the photometer is that the light between the four measuring channels is divided by semitransparent aluminum films. The efficiency of this photometer is higher than that of a photometer with a successive change of filters for stars brighter than 9-10 mag with a 0.5-m telescope. Consideration is given to the use of the photometer to obtain very accurate WBVR magnitudes of 15,000 stars during 1985-1988.
