1. Telescope. On the observational round you will use a simple Newton-system telescope with the mirror diameter D = 125 mm, focal length F = 1025 mm and 3 eye-pieces with focal lengths $f_1 = 12$ mm, $f_2 = 25$ mm and $f_3 = 38$ mm. Find on what distances ($\Delta x_1 =$, $\Delta x_2 =$, $\Delta x_3 =$ in vertical direction on the middle figure) it is necessary to move the corresponding eye-pieces (1,2,3) to readjust the telescope from observation of the sky objects to observation of a monkey sitting at a distance L = 50 m from you. (Your answer should have both formula and numerical values.) What eyepiece is the most suitable for observation of the monkey? Why?
