These premium Plossls offer the observer the ultimate in contrast. With superior lens polishing with multi-coating on all internal air-glass surfaces, these eyepieces provide orthoscopic-type definition with the added luxury of a 52 degree apparent field. In this regard, the extra field makes them more usable as an all-around eyepiece. Planets, as well as elusive nebulosities and clusters will be presented with dazzling detail. Standard features include 5 or 7 element designs with premium, fully multicoated, edge blackened optics, engraved lettering, slip-on eyeshield and standard filter threaded barrels. The result: Ultra-crisp imaging. In Antares' tests, these eyepieces have never been beaten at what they do. For the discerning observer. We also include a free bolt case with each eyepiece you purchase.
