郑州师范学院的天文台建于2005年,在观测台安装的KPW-400反射望远镜(如图1)是目前河南省最先进、分辨率最高的天文望远镜.天文望远镜是人眼的延长,是天文学研究最基本的工具.尽管目前天文观测已从光学时代进入全波时代,光学天文望远镜仍不失为最有效的观测工具.通常所说的望远镜如不加特殊说明,一般都是指光学望远镜. The Observatory of Zhengzhou Normal University was built in 2005 and the KPW-400 reflecting telescope installed at the observatory (Figure 1) is the most advanced and highest resolution astronomical telescope in Henan Province. Astronomical telescope is an extension of the human eye and is an astronomical research The most basic tool.Although astronomical observations have entered the full wave era from the era of optics, optical telescopes are still the most effective observation tools.Generally speaking, telescopes are generally referred to as optical telescopes unless otherwise specified.
