Explore Scientific 82° Series Eyepieces
Explore Scientific proudly announces their 82 degree series of premium eyepieces. Using advanced computer design, a combination of low dispersion and high refractive index optical glasses, and durable multilayer deposition coatings, Explore Scientific 82° Series™ extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics.

The visual effect of these eyepieces with their long eye-relief and their 82° apparent field is truly a full-immersion experience. Your eye is relaxed, allowing you to easily use the "averted vision" technique to study faint details across a huge field-of-view.
To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves.
Each eyepiece is meticulously assembled into precision machined metal lens barrels that maintain the perfect alignment of the optical train for years of rugged use in the field. Explore Scientific 82 degree series eyepieces are waterproof and nitrogen purged to prevent internal fogging.
Explore Scientific 82° Series™ N2 Purged Waterproof Eyepieces
Newly redesigned for the 2011 season, the new Explore Scientific 82° Series features the same Nitrogen purged and waterproof features of their 100° Series siblings. These new eyepieces jettison the original twist up eyecup design, shedding both size and weight in the process. As of early November 2010 the 4.7mm and 6.7mm variants are available, with the remainder of the line expected before year end. There are also persistent rumors of an 8.8mm variant, a focal length that we think this fine eyepiece line truly needs. Stay tuned for future developments.
In today's modern telescope industry there are many fine companies to choose from manufacturing top quality eyepieces. We invite direct side-by-side comparison with any other eyepiece of similar design, and we back our eyepieces with our exclusive Five Year Limited Warranty. We think that you will find Explore Scientific eyepieces rank among the finest obtainable and represent an outstanding value.
