TeleVue - 08.0mm RADIAN EYEPIECE

"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

Instadjust was developed for maximizing contrast while aiding in proper eye positioning for non-eyeglass wearers. It is essential,
since with the Radian's long eye-relief, non-eyeglass wearers could easily get too close to the eyepiece, resulting in vignetting
where edge field rays miss your pupil. The push-pull, click-stop adjustment permits fast positioning and maximum suppression of
environmental stray light.
	
Another unique development is the Pupil Guide. It helps non-eyeglass wearers, especially novices, zero-in and stay centered on
the exit pupil. The Pupil Guide is included with all Radian and Nagler Type 4s and fits under the soft, fold-down rubber eyeguard.
