Explore Scientific 68 Degree Series 34mm Waterproof Eyepiece - 2"

Explore Scientific 68 Degree Series 34mm Waterproof Eyepiece - 2"

Using advanced computer design, combinations of low dispersion and high refractive index optical glasses, and durable multilayer deposition coatings, Explore Scientific 68 Degree Series wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. Each 68 degree 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 68 degree apparent field is a unique experience. Your eye is relaxed, allowing you to easily use the "averted vision" technique to study faint details across a realistic 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 68° Series eyepieces come with a removable and foldable soft silicone rubber eyecup 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.
