A Photoelectric Photometer Attached to A 35-cm Telescope
In this paper the structure,performance indices and test observations of the photoelectric photometer are introduced which is attached to the 35-cm telescope at Yunnan Observatory.Alp21 Photomultiplier tube,a low-current amplifier of NWF-02-type and a paper-moving recorder are used in the photometer.The average accuracy of observations is 0.016 mag.This result consists with that of Johnson's B-V system approximately.
