Explore Scientific 1.25", 68° 20mm N2-filled eyepiece

Introducing a wide-angle, high-definition eyepiece, gas-filled, boasting a 68° apparent field of view.

This 68° field of view eyepiece is not only waterproof but also gas-filled, effectively warding off internal fogging, dust, moisture, and fungal blooms. Its gas filling ensures the durability and protection of its quality multi-coating. Cleaning becomes a breeze as heavy internal condensation cannot permeate between the lens elements. This eyepiece guarantees pristine observations for years to come!

Rest assured, image quality remains uncompromised. The eyepiece delivers sharp, high-contrast images across the entire field of view, even with 'fast' telescopes. High-quality glass, blackened lens edges, and patented EMD multi-coating ensure maximum contrast.

Additionally, standard features include a foldable rubber eyecup, standard filter thread, and a conical locking groove in the stainless-steel barrel. All 68° series eyepieces are parfocal, eliminating the need for focus adjustments when switching between them.
