You are building a reflecting telescope using a primary mirror with radius of curvature R = 3000 mm and diameter D =250 mm, and an assortment of eyepieces including a 7.5 mm, 15mm, and 30 mm. What is A) the focal length of the primary mirror, B) the F/# of the primary mirror, C) the system magnification using the 15 mm eyepiece? D) Which eyepiece would double the magnification of the telescope compared to that of the 15 mm eyepiece?
