Some info on telescopes. The purpose of a telescope is to really to do two things, not just one.The first is to magnify the image which is the obvious one. The other is to increase the amountof light which reaches your eye. The magnification is a result of the focal length of the lenses involved. THe amount of light that reaches your eye is based on the size of the primary lens OR mirror.
