Built with a 4-element lens configuration that presents a generous 52° apparent angle of view, the Meade Instruments Series 4000 6.4mm Super Plossl Eyepiece is equipped with a standard 1.25" diameter barrel to make it compatible with the most common size of focuser drawtubes and accessories. The relatively short 6.4mm focal length produces higher magnifications for making detailed observations of near and deep-sky objects. Anti-reflection multi-coated optics maximize light transmission, while blackened lens edges reduce internal light reflection for brighter and clearer views. A fold-down eyecup makes it easy to use with or without eyewear. Meade engineered this model to be parfocal with all other 1.25" Series 4000 eyepieces, requiring little or no re-focusing when changing magnifications during viewing sessions.
