The focal length of the eyepiece, combined with the focal length of the telescope, determine the magnification power. To calculate the power of your telescope with any particular eyepiece, simply divide the focal length of the telescope (300mm) by the focal length of the eyepiece (indicated in ¡°mm¡± on the eyepiece collar). For example, when you use the eyepiece H20mm with this telescope, the magnification will be 15X, and with a 3X Barlow lens, the magnification will be 45X.
