JYCTD 70mm AZ Astronomical Refractor Telescope with Tripod & 2 Eyepieces - Portable Telescope for Kids & Adults Beginners - Perfect for Moon Viewing, Stargazing & Astrophotography (Ideal for Backyard Astronomy & Outdoor Adventures)

Operation 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 (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.
