Discontinued - Tele Vue has discontinued this item, and we have no stock left. This listing will be left up for about one month, in case anyone wants to pull the specs. Sorry for the inconvenience!

One of the most expensive features of good optics is contrast, and the more, the better. The apparent field of view is wider than standard Plossl eyepieces, permitting you to see more.

"What sets Radians apart from other long eye-relief, short-focal-length eyepieces is superb image quality. Even discerning planetary observers who customarily choose Plössl or orthoscopic designs are switching to Radian." — Sky & Telescope, December 1999

All Radian eyepieces come with a Pupil Guide, which can be optionally used to align the eye [of non-eyeglass wearers and novice astronomers] with the cone of light exiting the eyepiece. The pupil guide easily installs under the rubber eyecup.
