  • Orion 3.8mm Ultrascopic, 1.25" Eyepiece

    ORION

    Orion 3.8mm Ultrascopic, 1.25
    The Ultrascopic eyepiece series offers unsurpassed image fidelity. Rather than having a single layer of magnesium fluoride on most lens elements, Ultrascopics are Ultra Multi-Coated, meaning that every air-to-glass lens surface is vacuum coated with multiple antireflective layers. There is no higher level of multi-coating. These coatings, coupled with a low-reflection barrel with blackened lens edges, improves both brightness and contrast of faint nebulas and galaxies. These premium 1.25" eyepieces employ 5- or 7-elements using high-refractive-index glass. Each produces a wide 52-degree apparent field of view (49-degree for the 35mm). Internally threaded for filters.
