视频CCD在天体定位应用中的两个问题

Two Problems In Application of the Video CCD System to the Position Determination of Celestial Objects

本文简要提出了视频ＣＣＤ在天体定位方面的两个问题；比例尺和定位精度的问题。并提出了两个确定比例尺的方法。本文认为影响比例尺和定位精度的主要因素是与所使用的图象板相关。

The application of the video CCD system to the position determination of celestial objects is briefly described in this paper. The scale factor and positional accuracy of the system are discussed. Two methods are presented for determining the scale. It is considered that the main effect on the scale and positional accuracy is related to the image card adopted in the system. The work will be of significant for the use of the video CCD system in astronomy.
