We developed an equatorial mount optical bench, on which various types of optics can be tested by introducing natural objects i.e.stars and nebulae. Pointing and tracking performances of the equatorial mounting are scrutinised in the series of photometric pbservations of variable stars. We determined the correction parameters of pointing (IH,ID,NP,ME,MA)to be input in the contol program of the telescope. The errors for pointing should be much improved by the correction. The other target of the program is to build a cryogenical telescope at the ground-level facility. We face several problems to be solved by small experiments.1) Tolerance of mechanical structures for CaF2 window.2) Long-term durance of motors under liquid nitrogen temperature.3) inavalability of materials for cryogenical mirrors due to damage of the campany by the Hanshin earth-quake. We will try to realize it by introducing array sensor with a new budget soon.

我们开发了一个赤道安装光学工作台，可以通过引入自然物体（即恒星和星云）来测试各种类型的光学器件。在一系列变星的光度观测中，对赤道仪的指向和跟踪性能进行了详细的研究。确定了输入望远镜控制程序的指向校正参数（IH、ID、NP、ME、MA）。通过校正，指向误差将得到很大改善。该计划的另一个目标是在地面设施建造一个低温望远镜。我们面临着几个需要通过小型实验来解决的问题：1）CaF2窗口的机械结构公差。2）液氮温度下电机的长期寿命。3）由于坂神地震造成的公司损坏，低温反射镜材料的不可用性。我们将尝试通过引入阵列传感器来实现这一目标。
