To achieve this magnification, place the Barlow lens into the eyepiece holder before placing the eyepiece onto the Barlow lens. The included Barlow lens in the box can help double the eyepiece magnification to 38x and 103x. Using NT114CF as an example, magnification is calculated by dividing the focal length of this telescope (500mm) by the focal length of the eyepiece (26mm, 9.7mm), which will give you 19x and 51x magnification. The magnification of a telescope is determined by its focal length and the eyepiece’s focal length. You may wonder how magnification, also called the power of the telescope, is calculated. The National Geographic Telescope NT114CF ships with two Possl eyepieces (9.7mm & 26mm) and 2x Barlow Lens that provide magnifications ranging from 19x to 103x.
