这是利用望远镜展示名为“牛顿圈”的光学效应，折射光线彼此干涉，形成了这些条纹。
This is the view through a telescope demonstrating the optical effect known as Newton's Rings, whereby reflected light rays interfere with one another and produce a pattern.
牛顿望远镜和反射折射望远镜都有一个次级反射镜(或称斜反射镜)，它们阻挡了一部分主反射镜的发射光。
Newtonian and catadioptric telescopes have secondary (or diagonal) mirrors that obstruct a small percentage of light from the primary mirror.
