3. In a Keplerian telescope, the focal length of the objective lens is: fo = 80 mm, the focal length of the eyepiece is: fe the telescope, in which D/f = 0.5. A field stop is placed in the back focal plane of the objective 10 mm. The size of the objective lens is an aperture stop of fo lens. Please use the thin lens equation to compute and find: 1) The location and size of exit pupil of the telescope from the eyepiece. 2) The entrance and exit window locations of the telescope. 3) Angular magnification power of the telescope.
