To increase the magnifying power of a refracting astronomical telescope, follow these steps: ### Step 1: Understand the Formula for Magnifying Power The magnifying power (M) of a telescope is given by the formula: \[ M = \frac{f_o}{f_e} \] where \( f_o \) is the focal length of the objective lens and \( f_e \) is the focal length of the eyepiece. ### Step 2: Increase the Focal Length of the Objective Lens ...
