Explore Scientific 14mm 82 Degree Waterproof Eyepiece - 1.25-Inch

Using advanced computer design, combinations of low dispersion and high refractive index optical glasses, and durable multi-layer deposition coatings, Explore Scientific 82-degree Series extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. Each 82-degree Series Nitrogen-Purged Waterproof eyepiece is internally sealed and purged with inert, dry nitrogen 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-degree 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 82-degree 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. 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.

ES 14mm 82

Excellent quality and value

ES 14mm 82 deg

This a decent EP for the money, in a 12.5" F-5 reflector the ES 14mm 82 was a bit dimmer but sharper than a ES 16mm 68 deg. for edge sharpness. I still prefer some of my plossil eyepieces for best image quality. If the added FOV is not sharp and coma free it is of less use. I am more satisfied with the ES 14mm 82 deg in a 80mm F-6 ED refractor

Excellent choice

I've wanted a nice wide-field EP for a long time now. And after doing some research, I decided on the 82' / 14mm from Explore Scientific. The very first night I used it, I was floored. It was pretty clear that this EP was a "winner". Not only does it offer great optics, and a wide FOV, but, the views were truly amazing. I can honestly say that this EP is just about "on par" with my 24mm TeleVue Panoptic, in terms of overall quality of views (Extremely sharp & crisp from edge to edge) and you can't beat the price! At $100 bucks, it's an incredible value, and one of the best EP purchases I've ever made. I'm glad that I decided on this particular EP, and my only regret is that I didn't buy it sooner. The only "Con" to speak of (maybe for some people) is that it's a large EP. You know, one of those "Hand Grenade" type of EP's, but, that doesn't bother me. I'll deal with a large EP, as long as it performs well. "Pros"? It's a no brainer! Great price, good eye relief, awesome quality glass, and it offers extremely sharp views. The views of Jupiter, and the star clusters I've viewed thus far, were amazing. Yeah, this EP gets a solid "Two Thumbs Up" from me! BTW: Scope used: Celestron 6SE SCT "Goto"

Ideal for deepsky

This eyepiece performed very well on my scope ! Sharp edge to edge view, great 82 degree field, comfortable eye relief. Highly recommended !
