Explore Scientific 18mm 82 Degree Waterproof Eyepiece - 2"

The 18 mm 82-Degree Waterproof Eyepiece - 2-Inch by Explore Scientific:

 

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.

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.

Explore 18 mm 82 degree 2" waterproof ocular

Very pleased with its performance. Not excessively heavy like some wide angle oculars.

Great eyepiece

Ok, it is not a Nagler, but then you aren't paying for a Nagler. But what you are getting is a great eyepiece with a immersive FOV. I purchased mine last year at Oregon Star Party and it has definitely become my favorite eyepiece. I use it in my red tube Coulter 13.1 dob and have had great results. This year I'll add the 11mm to my collection.
