Point accuracy of telescope is one of the important item for Satellite Laser Ranging (SLR). The star tracking can be used for correction telescope pointing. In this paper,a method of correcting telescope pointing using spherical harmonic model for SLR is discussed. The validity of this method is certified with observations.
