The catalog says:
These are Celestron’s top of the line eyepieces, utilizing a hybrid design of five elements. They feature long eye relief and a wide field, and each air-to-glass surface is fully multicoated to enhance contrast levels. These special eyepieces are computer designed to keep visual aberrations to an absolute minimum. They virtually eliminate the following aberrations: spherical, color, field curvature, coma, astigmatism, distortion and spherical distortion of the exit pupil. The inside surfaces and edges of all lenses are blackened, to keep out reflected light. Outside surfaces are flat black, with rubber grips for secure handling. Rubber eyecups are included both for comfortable use and to keep out extraneous light. Threaded barrels accept Celestron thread-in filters. Lens and barrel caps are included for safe storage.
(My 35mm Panoptics keeps this in the eyepiece case, so it sees very little use.)
In near-mint condition. Multi-coated optics in pristine condition. Very light set-screw marks on barrel. End caps included.
