This is a 12.5mm X-Cel eyepiece in excellent condition, with clean optics and an unmarked body.  Note that it is NOT the X-Cel LX; the X-Cel line preceded the current X-Cel LX line of eyepieces.  This 12.5mm X-Cel eyepiece has a 55-degree field of view, not the 60-degree field of view that you'd get with a current X-Cel LX eyepiece.  



If you are looking for an eyepiece that excels for planetary viewing, then Celestron’s X-Cel offers the unique features you are looking for. A 6-element fully multi-coated optical design, the X-Cel utilizes extra low dispersion (ED) glass on its most highly curved surfaces, to minimize chromatic aberration that can hinder sharp planetary views.





With a wide 55° apparent field of view, and a large 25mm clear aperture the X-Cel is one of the most comfortable eyepieces to use. Every X-Cel eyepiece is parfocal with each other, meaning little or no focusing is needed when changing from low to high power.





The X-Cel comes with soft rubber eyecups. In addition, if you are an eyeglass wearer, you will enjoy the 20mm eye relief available on each of the X-Cel focal lengths. Threaded barrels accept 1-1/4" thread-in filters.
