Celestron Eyepieces infoAn Overview of Celestron EyepiecesQuality Celestron EyepiecesCelestron provides several different classes of eyepieces to meet the needs of their users. A detailed description of each eyepiece series is listed below starting with the standard Celestron eyepieces and ending with their highest quality models. The 2" E-Lux series of Celestron eyepieces is available at OPT. This is a highly economical traditional Plössl optical design series. The 2" E-Lux class is the best value 2" eyepieces on the market. It is a 3-element fully multicoated optical design, which means that every air to glass surface is coated with several layers of high quality anti-reflective coatings. The 2" E-Lux Celestron eyepieces provide a wider field of view and longer eye relief (20mm) than standard Plössls. If you are looking to move up to a higher quality eyepiece, the Omni series of Celestron eyepieces provides lots of enhanced features in a wide selection of focal lengths. The Omni is a 4 -element premium symmetrical Plössl optical design. Features include blackened lens edges to minimize internal reflection and maximize contrast, and a multi-layer coating group on each lens surface to maximize light transmission and contrast. In addition, each Omni goes through a two-step anodizing process to prevent reflection from the top eyepiece barrel, unlike most other manufactures who use reflective surfaces. Threaded barrels accept 1-1/4" Celestron thread-in filters. The X-Cel series of Celestron eyepieces sports a 6-element fully multi-coated optical design and 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 series of Celestron eyepieces comes with soft rubber eyecups and a durable plastic case. In addition, you will enjoy the 20mm eye relief available on each of the X-Cel focal lengths, especially if you are an eyeglass wearer. Threaded barrels accept 1-1/4" Celestron thread-in filters.
