WebNewton started working on another type of telescope that he thought should get rid of chromatic aberration. Instead of using a lens to focus the light from a star, Newton used a mirror. He experimented with different … WebIt consists of a convergent lens as objective (i.e., the lens that forms the image); and its eyepiece (or ocular), placed in front of the focus, is a divergent lens. An upright image is produced. This simple refracting …
