Sky-Watcher 102x1000mm Refractor BK1021EQ3-2 Product Info

The word “refractor” means a telescope whose principal focusing element is a lens.  A refractor telescope is a type of optical telescope which is also referred to as a refracting telescope.  Its curved primary (or largest) lens gathers light, bends it, and sends it back to a focal point where it is further modified by the use of another set of lenses called the eyepiece.  The curvature and size of the primary lens dictates the amount of distance needed to achieve the focal point.
