What Is The Best Magnification For Telescopes? For most purposes, a telescope’s maximum useful magnification is 50 times its aperture in inches (or twice its aperture in millimeters) . So you’d need a 12-inch-wide scope to get a decent image at 600×. And even then, you’d need to wait for a night when the observing

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
