It had a convex objective lens and a concave eyepiece in a long tube. How does Galileo's telescope work? In Galileo's version, light entering the far end (1) passed through a convex lens (2), which bent the light rays until they came into focus at the focal point (f). The eyepiece (3) then spread out (magnified) the light so that it covered a large portion the viewer's retina and thus made the image appear larger.
