The Radian series of long eyepieces from Tele Vue Optics Inc. was designed for planetary and deep-sky observation with telescopes of any size, type or f/number. The 1-1/4-in.-diameter eyepieces use six or seven elements of multicoated, high-index glass, offering a 60° apparent field of view and 20 mm of eye relief. A click-stop housing with rubber grip ring, fold-down eye guard and snap-in pupil guide enable viewing with or without glasses while minimizing stray light. The eyepieces come in nine focal lengths from 3 to 18 mm.
