Condition:
These are used Celestron X-Cel eyepieces in excellent condition. The optics and bodies are clean. Any dust you see in the photos is easily removable - it seems that these develop an electrostatic charge such that the dust in the air is just attracted to the optics.
These are NOT the X-Cel LX; the X-Cel line preceded the current X-Cel LX line of eyepieces. These X-Cel eyepieces have a 55-degree field of view, not the 60-degree field of view that you'd get with a current X-Cel LX eyepiece.
NOTE: The 25mm eyepiece has some markings on the optics and can be seen in the image provided. The price has been adjusted accordingly.
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 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.
