Some Voyager with Sky Tour units come with a Barlow lens.This accessory will allow you to now have dual use of any eyepiece.Simply put the Barlow lens between the focusing mechanism and the eyepiece for reflector style telescopes,or the mechanism and the diagonal mirror on refractor style telescopes.Depending on the specification written on the Barlow lens,these accessories can double or even triple the magnification of the eyepiece when used with it.Remember,low power is always recommended,but higher powers are good especially on bigger and brighter objects such as the moon and planets.
