For example, consider
a telescope whose objective has a focal length of 100 cm and the eyepiece
a focal length of 1 cm The magnifying power of this telescope is
m = 100/1 = 100 Let us consider a pair of stars of actual separation 1¢ (one minute of
arc) The stars appear as though they are separated by an angle of 100 ×
1¢ = 100¢ =1
