| Abstract: | In order to study the tracking accuracy and pole orientation of the 300 mm refractive telescope at the Guangdong Astronomical Techniques Key Lab, we tracked two bright stars, Regulus and Sirius, for over two hours and developped a method to analyze the CCD images. The results show a considerable shift of the pole orientation in 2013 compared with its orientation in 2010, but the cy, which can cause an average shift rate of star position of less this paper is useful for calibration of telescope pole. telescope still maintains a high tracking accurathan 0. 4 arcsecond per minute.
