Features of the new Classic Eyepieces:
-Optical design and manufacturing specs based on the highly regarded Zeiss Jena .965 orthoscopics (not any Japanese or Chinese makes).
-Fully Multi-Coated: All air-to-glass surfaces coated with Baader’s HT MultiCoatings, specifically matched to each substrate.
-Excellent Ergonomics: The innovative recessed volcano top provides clearance for eyelashes and enables a comfortably located eyepoint without the stray light problems of a full volcano top.
-Integrated winged folding rubber eyecup: Eliminates distracting stray side-light, enabling full concentration on the object, as well as providing a thermally insulating and soft non-scratching top surface (ie, for eyeglass wearers). Also outstanding for BinoViewing. May be folded down or removed, if needed .
-50degree apparent field. Makes finding and centering objects at high powers easier than typical 40-45deg eyepieces.
-Threaded for 1.25″ Astro Filters.
