摘要
近年来我们为青海德令哈观测站安装了一台施密特(Schmidt)望远镜,还把云南天文台原德制施密特望远镜机架进行了设计、改装成"水平装置"。它们的改正镜口径约为Ф400mm,焦距约为800mm,用于观测人造卫星及空间碎片,用CCD作为接收器,提高了工作效率,为神州发射提供了资料。本文所述的是对这两台施密特望远镜光学系统的调整方法与步骤。
Recently a team including the author installed a Schmidt telescope in the Delinha Observational Station. In addition, we designed and fabricated a device named as ＂ level mounting＂ to replace the old mounting system of the Schmidt telescope of the Yunnan Observatory, which was originally made in Germany. For these two telescopes, the diameters of correctors are φ400mm or so, and their effective focal lengths are nearly 800mm. Both telescopes can be used for detecting man-made satellites and space debris, and thus can serve the launch mission of the ＂Shen zhou＂ spacecraft. With CCD chips as the receivers the working efficiencies have been increased substantially. The alignment methods and procedures of the optical systems of the two telescopes are described in detail by this paper.
