The Celestron X-Cel LX 5mm is a high power eyepiece, using a new six-element fully-multicoated optical system, and providing a wide 60° field of view. It provides good high magnification views with short focal length refractors and fast focal ratio/short focal length reflectors. Its full multicoatings provide high contrast that makes it a good choice for splitting close binary stars and for seeing faint low contrast lunar and planetary details. If you were to use this eyepiece with a 2000mm focal length Schmidt Cassegrain Telescope (F/10) you would be more than pushing the limits of maximum usable magnification.
It has a twist-up rubber eye cup and a usable eye relief of 16mm, for virtually unvignetted use with eyeglasses. The no-slip rubber grip ring means a secure and comfortable grip when handling in cold weather. The Celestron X-Cel LX 5mm comes with dust caps for both ends of the eyepiece and a bolt-type plastic storage case.
