Corded Illuminated Reticle Eyepiece in excellent condition. This is the older Japanese made version, not the el cheapo Chinese made newer one. I bought a 9mm cordless meade eyepiece and promptly sent it back due to inferior optics and build. This eyepiece is heavy, solid, with good coatings. It plugs into a battery pack, which is included. It has been sitting in a closet for the past two years, so I have resigned myself to selling it.
