SUMMARY
The magnification of a 10" reflecting telescope with a focal length of 1250mm and a 250mm eyepiece can be calculated using the formula M = -di/do. The focal length of the telescope and the eyepiece are critical in determining the image distance (di) and object distance (do). By applying the lens formula 1/f = 1/do + 1/di, users can derive the necessary values to compute the magnification accurately.
