Show Development of Telescope The first practical refracting telescope tele-scope was invented by Hans Lip-pershey, Lip-pershey, a spectacle-maker in Mid-dleburg, Mid-dleburg, Holland, in 1608. As originally origi-nally devised, it was a monocular opera-glass, composed of a convex and a concave lens fitted at opposite oppo-site ends of a tube. This original telescope was a toy compared to the 200-inch Mt. Palomar telescope, which astronomers expect will pen-ttrate pen-ttrate space six septllllon miles. ' |
