Editorial Reviews
Product Description:
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.

Content: I bought the 25mm X-Cel on ebay. I got it as a replacement for the cheaper 26mm Celestron no-name Plossl that came with my telescope. Compared to the generic Celestron 26mm, the X-Cel eyepiece is a huge improvement. The apparent field of view is dramatically wider, allowing me to watch planets for over twice as long before I need to adjust the scope. Also, the eye relief is exceptional. With the cheaper eyepieces, I needed to press my eye into the cup. With the X-Cel, I have my eye at a comfortable 2 cm distance and I get a huge view. This eyepiece also gives a noticeably sharper image than the cheaper Plossls. The X-Cel is also significantly larger and heavier than the generic Plossls. With a 55 degree FOV, it is a step up from Celestron's Omni series and significantly better than Celestron's generic Plossls, which come in their eyepiece kit and with their budget scopes. Having looked through Celestron's Ultima and Axiom eyepiece line, the X-Cel is not as bright or sharp at the same focal length, and does not have an ultra-wide FOV, but at one third the price, it seems to be the best value for the price of Celestron's eyepiece line. The X-Cel line is touted for lunar and planetary viewing, which are what I have used mine for. I have not try this eyepiece with deep space objects yet. I did notice some minor coma around the edges of this eyepiece in my f/5 130 mm Newtonian, but that was not unexpected. I tried it with my Celestron Ultima Barlow with excellent results. I plan to purchase more of the X-Cel eyepiece line, as it is by far the most comfortable eyepiece I own.
Summary: Very nice eyepiece
