I have for sale a 15mm Antares Plossl bought here on Astromart as a Antares Ultima eyepiece. I comes with both end caps and box. There are a few barrel marks from the set screws. Optics appear to be excellent and "Japan" is imprinted on the barrel. I'd like $40.00 shipped anywheres in Conus. Email with any questions. Thanks for looking and clear skies to all.
