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. Easy to install The installation of the telescope is very simple. As long as you follow the instructions, you can install all the accessories in ten minutes. No extra tools are needed. You can explore the universe at any time With the 3 eyepieces and 3X Barlow lens, Refractor Telescope could offer a magnification of 15X to 150X. ToyerBee refractor telescope was designed to provide views of the moon’s craters, Jupiter’s major moons, and Saturn’s rings. As a terrestrial telescope, the refractor telescope delivers great views of mountains, valleys, and many other features of the world around.
