The telescope magnification refers to the magnification of the telescope, that is, when observing objects through the telescope, the magnification of the object's viewing angle is relative to that of the naked eye. For example, 10 * 500 means that the magnification of the telescope is 500 times, that is, the objects observed through the telescope will be 500 times larger than those observed with the naked eye. And 10 means that the eyepiece power of the telescope is 10 times, that is, the object observed through the eyepiece will be 10 times larger than that observed with the naked eye. To sum up, 10 * 500 means that the object will be magnified 500 times when viewed through the telescope, and 10 times when viewed through the eyepiece.
