Astronomy * Celestron X-Cel Series -1-1/4'' 25mm Eyepiece - CSN 93393 - Astronomy
New Page 1 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 and a durable plastic case. 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" Celestron thread-in filters.
