Save £79! Celestron's Ultima eyepieces were voted best in their class by Sky & Telescope magazine. These eyepieces use a 5-element optical design and feature long eye relief and wide fields of view. Each of the air-to-glass surface on the entire Ultima range are fully multicoated to enhance contrast levels. The Ultima series of Celestron eyepieces were computer designed to keep aberrations to an absolute minimum. They virtually eliminate spherical, colour, field curvature, coma, astigmatism, distortion and spherical distortion of the exit pupil. The inside surfaces and edges of the lenses are blackened to keep out reflected light. Outside surfaces are flat black and include rubber grips for secure handling. Rubber eyecups are also included both for comfortable use and to keep out extraneous light.
