Using advanced computer design, combinations 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. Each 82° Series Argon-Purged Waterproof eyepiece is internally sealed and purged with inert, dry argon gas to prevent internal fogging, to halt the intrusion of fine particulates and fungus, and to maximize the life of the internal coatings.

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. Just check out this animation of how Explore Scientific Eyepieces field of view works and read about how Scott Roberts uses them:

"I now use the 82° Series eyepieces for most of my deep sky work at the telescope. I love the way that objects like M31 in Andromeda, the Orion Nebula, distant galaxies, and beautiful star clusters stretch across the huge field of these eyepieces. I feel more connected with the universe at large and as I study the treasure of stars in my eyepiece I am reminded of the distances and age of the cosmos and the constant discoveries that are being made by professional and amateur astronomers alike.

It is generally accepted that an eyepiece with a larger apparent field of view (AFOV) will produce a larger true field of view (TFOV) if we are comparing different eyepiece designs of the same focal length. Large apparent field eyepieces give you what I call "full- immersion" viewing. With eyepieces that have small apparent fields (like Kellner ("K"), Modified Achromatic ("MA"), Orthoscopic ("OR"), or Huygens ("H") designs) if the eypieces are of good optical quality, the resolution, contrast, magnification, and sharpness will be there, but the observer tends to be more "removed" from the experience of observing the object. You feel like you are looking down a dark tunnel to see the object at the end of the eyepiece, and your eye tends to strain a little as you lock your eye straight down the eyepiece. In visual astronomy, the harder you try to look as you strain your eye, the less you see.

But when you use eyepieces of larger apparent field, you have a much wider visual angle to scan your eye across the image inside the eyepiece. By scanning your eye from edge to edge you can more comfortably and naturally look into the eyepiece, and as you relax your eye, you begin to see finer and fainter details. This "immerses" you into visual experience of astronomy. The experience for many who first use extreme wide angle eyepieces like the 82° Series is often quite overwhelming as they start to really connect with the universe. The cost of such eyepieces is generally more, but experienced observers often feel the expense is worth it.

To calculate the true field-of-view with any eyepiece, first calculate the magnification the eyepiece is producing by dividing the telescope's focal length by the eyepiece's focal length. Then divide the apparent field of view of the eyepiece by the magnification. This will give you a number in degrees of the actual section of the sky that you are seeing through the eyepiece, the true field of view."
-- Scott Roberts

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 82° 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.

With this kit, purchase four different eyepieces of such high quality at once- certainly a purchase of great value! With the 6.7mm, 11mm, 18mm, and 30mm 82° series eyepieces all bundled together with a sturdy, safe, secure soft-inside case, you'll find yourself well equipped for a variety of situations- the four different scopes each being ideal for different size scopes!

In today's modern telescope industry there are many fine companies to choose from manufacturing top quality eyepieces. Explore Scientific invites direct side-by-side comparison with any other eyepiece of similar design, and they back their eyepieces with a Lifetime Warranty. We think that you will find Explore Scientific eyepieces rank among the finest obtainable and represent an outstanding value.
