Plossl 17mm Telescope Eyepiece, 1.25"
This Orion SiriusŪ 17mm is an ideal medium-power eyepiece. Use it to get a closer look after finding a night sky object with a longer focal length eyepiece. It provides 70x magnification with a 1200mm f/l telescope and is excellent for star clusters. This eyepiece is fully coated for maximum contrast and threaded to accept standard 1.25" eyepiece filters. The folding rubber eyecup helps block stray light.
