In the second half of the seventeenth century, therefore, the Galilean telescope was replaced for terrestrial purposes by the "terrestrial telescope," which had four convex lenses: objective, ocular, erector lens, and a field lens (which enlarged the field of view even further).

在下半年的十七世纪，因此，伽利略望远镜取代地面的目的，由"地面望远镜，"其中有四个凸镜头：目的，眼，竖镜头，和野战镜头。
