This is a beautiful 1970's Celestron 25mm Kellner Telescope Eyepiece. Made in Japan by Circle T, Tani. Tani made some of the best telescope optics of the 1960's-80's. This eyepiece is standard 1.25 inch diameter. It is threaded for filters. 25mm gives a nice medium-low power. The glass is outstanding, and the barrel shows very slight wear on the bottom of the black volcano top. You will love this eyepiece with your telescope.
