When it comes to telescopes, there are two important concepts to consider: the maximum useful magnification and the magnification achieved with a specific eyepiece. The maximum useful magnification refers to the optimal level at which the telescope’s optics perform. Going beyond this limit will result in a decrease in image quality. To calculate the maximum…
