1. Mount the telescope on a tripod, adjust the angle, remove the dust cover, and attach the eyepiece. 2. Align the finder scope with the object, make it in the center of the field of view. 3. Rotate the focus wheel slowly until see a bright, clear image. About Magnification: 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 (500mm) by the focal length of the eyepiece (indicated in “mm” on the eyepiece collar).
