The Explore Scientific 68° Eyepiece 40mm offers great eye relief, rugged, Argon-purged construction and great optical resolution and colour correction.
The Explore Scientific 68° Series Eyepieces were designed for those who prefer longer eye relief but still want to enjoy a field of view that is wider than a classic Plossl or Orthoscopic style eyepiece. If you wear eyeglasses and either want or need to keep them on while observing, the extra long eye relief built into the 68° models will allow you to do that and still observe comfortably. As you can see from the chart shown above, the eye relief in this series starts at almost 12mm on the 16mm model and increases quickly until it reaches a maximum of 31mm on the 40mm model. There are four Explore Scientific 68° eyepieces…the 24mm, 28mm, 34mm, and 40mm…that sport an eye relief of over 18mm, which is perfect for eyeglass wearers.
Of course, you do not have to wear eyeglasses to appreciate comfortable eye relief, or the quality that lives in each Explore Scientific 68° eyepiece. From the rubber grip and folding eyecup to the enhanced EMD coatings for superb contrast, we think you'll agree that these eyepieces are a perfect solution for dropping the power down on your telescope, which will increase the exit pupil size and allow you to see the faintest objects that your telescope is capable of.
