Telescope Magnification:
Magnification = focal length of objective lens (fo) / focal length of eye piece lens (fe)
BEST MAGNIFICATION = biggest focal length of fo and smallest focal length of fe
magnification of 50 (or 50x)
means
a) object appears 50 times larger with naked eye
b) object appears to be a one fiftieth of the distance
c) the telescope makes the object's angular size look 50 times bigger
