Most quality telescopes require the use of an eyepiece as part of the magnification power of the telescope. If you have a telescope with a single eyepiece, you will want to investigate using one or two different ones for different purposes. The eyepiece telescope has this advantage of those that do not have a changeable eyepiece.
The eyepiece plays a major role in the magnification power of an eyepiece telescope. In order to calculate what the magnification would be with a different eyepiece you would divide the focal length by the eyepiece focal length. Since the focal length of an eyepiece telescope will remain constant, by changing the eyepiece you can change the power.
Not everyone changes an eyepiece to increase the magnification, especially if wanting to view areas that are closer or they want a wider field of view. One reason to reduce the magnification may be to create a finder lens for your telescope to be able to find an object. With a strong eyepiece telescope, finding the moon through the normal magnification could be like trying to find it while looking through a straw.
