Long term observation of stellar photometer in daytime and night needs to calibrate several stars. Langley calibration observation for numerous stars is a time-consuming job and some stars’ elevation angle suitable for calibration often occurs in daytime, which is not suitable for calibration due to sky background and turbulence. In this paper, a transfer calibration method of different star was realized by the combination of Astronomical Langley observation, stellar apparent magnitude and effective temperature, which is based on the calibration constant of one reference star that would be calibrated by Langley observation. A field campaign was carried out to check the transfer calibration results against two-star method calibration observation by a stellar photometer. Experimental result shows that the transfer method described in this paper is preliminarily feasible, and the method described can be used for stellar photometer real time calibrating.
