The Celestron X-Cel LX 2.3mm is a extremely high power eyepiece, with a very short focal length, uses a new six-element fully multicoated optical system, and provides 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.
The focal length of this eyepiece is not recommended for use with long focal length refractors, reflectors, or catadioptric scopes during anything less than absolutely perfect observing conditions. It is mostly for use with smaller aperture telescopes, with short focal lengths.
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 2.3mm comes with dust caps for both ends of the eyepiece and a bolt-type plastic storage case.
