Designed for demanding observational astronomers, the Explore Scientific 68° Series 16mm Waterproof Eyepiece combines low-dispersion optical glass with durable multilayer coatings to maximize light transmission and minimize reflections. Featuring advanced Argon-purged waterproofing, this wide field eyepiece prevents internal fogging, fungus formation, and elemental contamination even under extreme humidity. Every unit is submerged and tested in one meter of water for 30 minutes to guarantee an impenetrable seal. The parfocal optical design allows seamless focal length changes without constant refocusing, while the soft silicone rubber eyecup ensures maximum comfort during long visual sessions at the limits of your telescope's magnification.

Why is the Explore Scientific 68° Series 16mm Waterproof Eyepiece purged with Argon gas?
Argon gas purging creates an inert internal environment that prevents internal glass fogging, protects optics against mold or fungus growth, and extends internal component life far better than traditional nitrogen.

With an 11.9mm eye relief and a soft, foldable rubber eyecup, the Explore Scientific 68° Series 16mm Waterproof Eyepiece provides comfortable visual viewing for most observers.
What does parfocal mean for the Explore Scientific 68° Series 16mm Waterproof Eyepiece?
Parfocal means that when you switch between different focal lengths in the Explore Scientific 68° Series, the focus point remains nearly identical, minimizing the need to readjust your telescope's focuser.
