This paper expounds the shortcomings and shortcomings of the traditional standard telescope by analyzing the principle and structure of the traditional standard telescope. The application of CCD and autofocusing technology in the telescope of the antenna is measured, and the CCD and autofocusing technology are analyzed and demonstrated. After the transformation is completed, the feasibility of the experiment is verified. Finally, the retrofit of the new telescope and the traditional standard telescope bin calibration methods and data for comparative analysis. The experimental results show that the improved new telescope has the characteristics of high calibration precision and convenient operation, and realizes the high precision focusing control function of the remote control telescope.
