| Abstract: | This paper describes a new photoelectric photometer controlled by a microcomputer. The filters, stars and sky background can be changed by the computer according to the preset control on the keyboard. The photometer is used for real-time data acquisition, processing and display during observations. It can carry out two kinds of work: one is photon-counting and the other is DC amplifying-F/F converting. We give one typical light curve obtained with this photometer which has been routinely used since 16 Nov. 1983. The standard error of the magnitude difference between comparision stars and check stars is smaller than 0.003 mag. The color system can be transformed into the international standard UBV system and the uvby system. |
