You'd find that you have to turn the telescope at a slight Angle to line up the object.

你发现必须把望远镜转一个轻微的角度以和该物体对准。

Firstly, a telescope system is made up with a concave lens and a long-focus convex lens, by which the angle of the parallel beam from the collimator can be change.

该方法借助一个焦距较长的凸透镜与被测凹透镜组成无焦系统，可以使准直管出射光束的张角发生改变；
