Astronomical telescope The astronomical telescope consists L 1 L 2 of two convex lenses of focal lengths f 1 and f 2 placed at a distance = he image of the f 1 f 2 d d = f 1 + f 2 . The image of the astronomical telescope is inverted L 1 L 2 Terrestrial telescope The terrestrial telescope consists of l f fl lt h d f 1 f 2 d two lenses of focal lengths f 1 and f 2 placed at a distance d = f 1 -| f 2 |. The image of the terrestrial telescope is upright The magnification of both telescopes is given by the equation: 2 1 f f m = (page 2)
