Calculate focal length of telescope

WebAn objective of an astronomical telescope has a diameter of 12.5 cm and a focal length of 85.0 cm. When it is used with an eyepiece having a focal length of 2.50 cm and a diameter of 1.50cm, what will be (a) the angular magnification, (b) the diameter of the exit pupil, (c) the object-field angle, (d) the image-field angle, and (e) the eye relief? WebThe magnification only depends on the ratio of the focal length of the objective f and the focal length of the eyepiece f e: MP = f / f e. Common eyepieces for telescopes are 26 mm and 12.5 mm. An f/10 telescope of 8" aperture (203 mm) would provide corresponding magnifications of 78X and 162X for these two eyepieces.
