TeleVue Radian Eyepieces

TeleVue Radian Summer Sale

Now for a limited time, purchase any two TeleVue Radian eyepieces and receive a third Radian eyepiece for free. TeleVue Radian eyepieces offer a 60 degree apparent field, which is far wider than most other planetary eyepieces. What's more, TeleVue Radians provide a generous 20mm of eye relief, making them very comfortable to use. Most other lunar / planetary eyepieces suffer from extremely short eye relief, making them tedious to use. The longer focal length eyepieces in this series are also a great choice for observing deep sky objects in most amateur telescopes. This offer is valid through September 30th and is subject to availability.

"That's a great offer, but what if I don't need three eyepieces?"

We are hearing those words a lot these days. Not to worry, just give us a call toll free at 888-947-2673 for a price that is simply too low to advertise.

TeleVue 3mm Radian

Some of us may need to wear eyeglasses while observing, while others simply prefer the greater comfort offered by eyepieces with long eye relief . This can be especially true for planetary observing where we tend to spend long periods at the eyepiece studying a single object. TeleVue Radian eyepieces offer a comfortable 20mm of eye relief combined with a 60 degree apparent field. They employ fully multicoated exotic glasses, providing full field sharpness, true orthoscopic linearity and high contrast for critical planetary viewing. The size and weight blend also makes the Radian preferable for small instruments and bino-viewers, and allows the convenience of being parfocal with other 1¼" TeleVue eyepieces.

• 60° AFOV with full-field sharpness on any f/# telescope
• High efficiency, tuned multi-coatings to maximize contrast
• Adjustable eyeguard for blocking ambient light, fully retractable so as not to rob eye-relief
• 20mm Eye-Relief for eyeglass wearers or Dioptrx users
• Distortion correction for day and night use
• Compact size and weight: bino viewer friendly

"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 TeleVue Radian eyepieces are directly compatible with TeleVue's DIOPTRX™ astigmatism correcting lens system. The performance inherent in EVERY TeleVue eyepiece is verified for you at f/4; quality assurance available nowhere else. What other brand of telescope eyepiece can make that claim?
