I am offering two 82 mm/500 mm FL RR Achromats made by Sky Objectives based in Netherlands. These are mint and unused achromatic doublet lens. The lens are fully coated. I bought these for a large binocular project that I since abandoned. The RR Achromats have excellent optical quality. These cost new $99 plus shipping cost from Europe. I am offering each lens for $60 which includes 2-day priority shipping and insurance. They also come with a PVC lens cell. Thanks for checking out my ad.
