Then, if the focal length of the Barlow is FB, the thin lens equation says that: -1/d1 + 1/d2 = -1/FB (Eq. 1) The magnification factor of the Barlow is: MB = d2/d1 (Eq. WebbThe Kepler’s telescope uses two converging lenses. The Galilei’s telescope uses a con-verging lens for the objective and a diverging lens for the ocular. Fig. 3 (right) shows the vertical scale which has to be placed at a distance of approx. 10 m in front of the optical bench to determine the magnification of the telescope. The experiment
