This medium power X-Cel eyepiece is 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" thread-in filters.
