Description

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. 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. Let's start our space adventure!
