  • The narrowband UHC filter, like the O-III filter, allows only the two doubly ionized oxygen

    lines (496 and 501nm) and the hydrogen-beta line (486nm) emissions through while blocking
    everything else, thus highlighting and revealing the beauty of planetary and emission
    nebulae. This filter permits superb views of objects like the Orion, Lagoon, Swan and other
    extended nebulae. It performs well in smaller aperture instruments owing to its greater light
    transmission than the O-III, yet still suppresses light pollution well. The UHC filter is the best all-
    around dark-sky nebula filter. Brighter nebulae benefit from increased contrast, and hard-to-
    see nebulae become visible.

    High quality filter designed to enhance your views of Emission Nebulae such as the Swan, Lagoon and the Orion Nebulars.

    ♦The UHC filter is the perfect choice for the deep sky observer

    ♦Eenhance your views of Emission Nebulae. e.x. the Swan, Lagoon and the Orion Nebulars.

    Available in two sizes, threaded to fit either standard 1.25” or 2” astronomical eyepieces.
