Explore Ultra-Wide Eyepieces - Comfort, Quality, Value

 

Explore Scientific 82° Series™ eyepieces, with their 82° apparent field of view, immerses you in a very comfortable ultra-wide field that naturally promotes relaxation at the eyepiece. When you relax your eyes and take in the scene presented before you, it is much easier to observe for longer periods of time, and details begin to materialize that may not have become apparent to you at first glance. Another great benefit of ultra-wide eyepieces is the ease with which you can gaze, not directly at an object, but slightly to either side. This skill, called using averted vision, is especially helpful when observing faint objects, because using averted vision puts the image on a part of your eye that is more sensitive to light, allowing you to see fainter images.



Explore Scientific 82° Eyepiece Highlights

 

Optimized Optical Design Explore 82° Series ultra-wide eyepieces are optimized through each design, fabrication, and testing process to produce flat-field images that have high contrast and resolution.

 

Exotic Glass Combinations for Optimum Results Eyepieces are constructed of 6 or 7 lens elements (depending on the focal length) that are fabricated from combinations of Dense Crown, Light Crown, Dense Flint, and Lanthanum optical glass.

 

Durable Coatings & Finishing Touches Each element in your Explore Scientific 82° 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 all 82° Series eyepieces are housed in a gas-purged, waterproof barrel that keeps them as pristine as the day they were manufactured. Cleaning is much easier, and there is no need to worry about water or fluid becoming trapped in between elements due to rain, spills, heavy dew, or getting over-enthusiastic with lens cleaning fluid.

 

Tapered Barrel for Extra Security The insert barrel of each eyepiece is double-tapered to allow smooth insertion to, and removal from, a telescope's eyepiece holder or diagonal, however 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. The barrel (1.25" or 2", depending on the focal length) is threaded to accept standard screw-on filters.

 

Optional Focal Extenders for Extra Magnification Explore Scientific makes a wide variety of eyepiece focal lengths, allowing a change in magnification for just about any observational study you can think of. However, if you would like to get "double duty" out of the eyepieces in your accessory case, while still retaining the eye relief of that eyepiece, use Explore Scientific Focal Extenders.

 

Producing optics for amateur astronomers that can be relied upon to deliver research-quality images requires a solid design, careful fabrication, multiple tests, and continued diligence to make sure we are always doing everything we can to produce a cutting edge, quality product. This is what we do at our facilities at Explore Scientific, and to insure your satisfaction, we back each eyepiece with the Explore STAR Transferrable, Extended Life of the Product Warranty, so you can keep exploring!

 

 

Explore Scientific Eyepieces are Gas-Purged and Waterproof to Make Cleaning Easy

 

Cleaning Waterproof Eyepieces

 

Because we gas-purge the body of each eyepiece to make it fully waterproof, the internal elements will remain as pristine as the day they were assembled. The sealed, dry environment is impervious to internal fogging and contaminants, such as fungus growing in between the lens elements. To insure a perfect seal we test every eyepiece in one meter of water for 30 minutes.

 

A clean eyepiece reveals the utmost contrast and light transmission from your telescope's optics. Our waterproof eyepieces are easy to clean, and there is no risk that water or cleaning solution will seep around the edges of the optics to be trapped between elements. Immersing Explore Scientific waterproof optics under running water is the safest way to remove grit, sand and other hard-to-remove particulates from the external lens elements. But don't try this with other non-waterproof eyepieces!

Explore STAR Extended and Transferrable Life of the Product Warranty

 

Explore STAR Warranty

 

We are always striving to improve the quality of Explore Scientific eyepieces and to enhance your experience as a user of our products. This is why we created the Explore STAR Transferrable Extended Life-of-the Product Warranty Program.

 

For as long as we manufacture a product it is under warranty, no matter how many times it is sold or traded to another individual. And when we stop manufacturing a given model (which is the end of the Life of the Product), we will extend the warranty automatically for another five years.
