| 摘 要： | 利用望远镜的恒动跟踪，对两颗恒星进行无斗星曝光０．５小时，扣除蒙气差影响，用球面三角方法计算出望远镜极轴指向的偏差在赤经和赤纬方向上的分量，据此对望远镜极轴进行调整，就可以方便地把望远镜极轴指向调整到较高精度。

| Abstract: | This paper is gives a method of determining the deviation of the telescope polar axis pointing to the North Pole. Its principle is that the length of star images during photographic tracking without guiding can be measured .Taking into account the effect of atmospheric refrraction. we can get the length caused by the length caused by teh deviation of polar axis and then determine the deviation by means fo sphericla trigonometric calculation,It will be easy to adjust the polar axis of the telescope according to the result. |
