How Do You Calculate Eyepiece Magnification?

How Do You Calculate Eyepiece Magnification? It’s equal to the telescope’s focal length divided by the eyepiece’s focal length. As a rule of thumb, a telescope’s maximum useful magnification is 50 times its aperture in inches (or twice its aperture in millimeters). What is magnification eyepiece? 2 Eyepieces. An eyepiece is essentially a combination of

Does Aperture Affect Magnification? Does aperture affect magnification? The smaller the focal length of the eyepiece, the greater the resulting magnification on any given telescope. Aperture is entirely irrelevant in this case. It’s worth being able to work out how much magnification you’re using because, unlike aperture, more isn’t necessarily better. Does magnification depend on
