Product Details

  • Pushing the boundaries of eyepiece design, Explore Scientific spent years developing the 120-degree eyepiece, adding to it the bonus of an Argon purged interior space ensuring that your investment is immune to the outside environment and your eyepiece never falls victim to a damp night.

    Like all Explore Scientific eyepieces, the lens elements of the 120-degree eyepiece are meticulously cleaned and aligned before being installed in their precision machined lens barrels.

    Each lens and lens grouping have EMD (Enhanced Multilayer Deposition) Coatings and are edge-blackened to eliminate light scatter and maintain image contrast.

    Contrast is further enhanced with baffles that mask and deflect unwanted stray light.

    These eyepieces with their enormous apparent field of view give the ultimate panoramic experience and with such a wide field, your eye can truly relax and bring in even the faintest details.

    Each 120-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. Waterproof eyepieces are easier to clean, and there is no risk of cleaning solution migrating from the top of the lens and seeping around edges to be trapped in between elements.

    To make sure, every 120-degree eyepiece is tested by submerging them down to 1 meter of water for 30 minutes. After announcing Explore Scientific's line of telescopes at the Astronomical League Conference in the summer of 2008, they decided to focus on extreme performance, ultra-wide angle eyepiece designs as well. Explore wanted to offer ultra-wide angle designs in popular formats at lower prices. Now more astronomers could experience the benefits of the amazing panoramic views these eyepieces provide.

    Each and every Explore Scientific eyepiece is inspected both at the factory and again at their USA facility in California to ensure the highest degree of quality. Final visual and cosmetic inspections where the assembly integrity, cleanliness, and optical performance (including a test for visual image edge consistency) before shipping them to OPT.
