Product Description

The Explore Scientific 68 Degree Series 40mm Eyepiece is 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 this 68deg. model will allow you to do that and still observe comfortably. From the rubber grip and folding eyecup to the enhanced EMD coatings for superb contrast, this eyepiece is 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.
  • Optimized Optical Design: Explore 68 Degree Series 40mm Eyepiece is optimized through each design, fabrication and testing process to produce high contrast, high resolution image
  • Durable Coatings and Finishing Touch: Each element in your Explore Scientific 68 Degree Series 40mm eyepiece is fully multi-coated, resulting in bright, sharp images and every element has blackened edges to reduce internal reflections and increase contrast
  • Waterproof, Fog-Proof Housing: The internal optics of 68 Degree Series 40mm eyepiece is housed in a gas-purged, waterproof barrel that keeps them as pristine as the day they were manufactured
  • Tapered Barrel for Extra Security: The insert barrel of 40mm eyepiece is double-tapered to allow smooth insertion, the wide dimension of the taper helps prevent the eyepiece from falling out of the telescope should the set-screw holding it in place become loose
