Abstract

[It’s a telescope’s eyepiece that does the actual magnifying of the image brought to a focus by the objective lens or primary mirror. It also happens to be the element in the optical train that is most often overlooked as the source of good or bad performance of the overall system. An eyepiece can literally make or break even the best of telescopes. Small imported refractors from the Far East are especially notorious for having poor-quality oculars. And since a telescope would not be able to function without an eyepiece (at least for visual observing), an eyepiece can really be considered a necessity, rather than an accessory as listed here.]
