This is a discontinued item. We recommend the Explore Scientific 30mm 82° Argon Purged 2" Waterproof Eyepiece as a replacement.
Wide-field eyepieces are all the rage these days, with some offering fairly impressive performance while others simply are not up to the task, especially in shorter f/ratio telescopes. Explore Scientific recently shook things up with their 100 degree apparent field eyepiece series, and now have taken on somewhat more modest fields with their new 82 degree series units. The new 30mm Explore Scientific (ES) 82 degree series eyepiece is a good example of just what Explore Scientific has achieved with the new line for a lower cost than many other wide field designs.
Using advanced computer design, combinations of low dispersion and high refractive index optical glass, and durable multi-layer deposition coatings, Explore Scientific 82Â° Seriesâ„¢ 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 82Â° 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.
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. The 82Â° Series eyepieces come with a twist-up rubber eye-guard that raise to the desired height for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope.
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.
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.
