2.16m光学望远镜是我国乃至东亚最大的光学望远镜。但是在当今世界上已有10m口径的光学望远镜,在空间的哈勃望远镜的口径也比它大,它在世界望远镜排序中只能算中等偏小。更何况我们能给予它的设备改造和运行费用都远比国外同等口径的望远镜低,能否利用它做出一批一流的科学成果?经过从1989年安装完成到1999年这十年的努力,我 2.16m optical telescope is the largest optical telescope in China and even in East Asia. However, in the current world, 10-meter optical telescopes are already in existence. Hubble telescopes in space have a larger caliber, which can only be modestly smaller in the world's telescope sorting. Not to mention we can give it equipment reconstruction and operation costs are far lower than the telescope of the same caliber abroad can make use of it to make a number of first-class scientific achievements? After the installation from 1989 to 1999, the efforts of this decade, I
