    Orion has made the difficult decision to close our warehouse facility in the Netherlands. With the continuing supply chain/logistics challenges and slowness in the economy we have found that it is not economically feasible to maintain operations in the UK and Europe.

    We have therefore stopped taking orders on this website. We apologize for any inconvenience.

    We will continue to have Orion dealers in Europe to meet the needs of Orion consumers. We will also continue to honor the 30-Day product return period as well as honoring the Orion warranty for purchases made in the UK and Europe.

    Our US-based Customer Service Representatives are here to help. Contact them via email at support@telescope.com or in the United Kingdom, via phone at 0-800-041-8146 (Monday-Friday between the hours of 1300 and 2400 GMT).

    £ 99.99 - £ 129.99
    Payment Options
    • Our Hydrogen-Beta Filters help significantly improve resolution of expecially faint and challenging nebulas such as the Horsehead, California, and Cocoon Nebulas
    • A Hydrogen-Beta filter enhances views of nebulas by isolating the hydrogen-beta spectral line centered at 486.1 nm with a 12nm band-pass
    • Specialized Hydrogen-Beta filter blocks all other wavelengths of light and effectively blackens the background sky, allowing the faint nebula to become clear
    • For best results use a Hydrogen-Beta eyepiece filter with a moderate to large aperture telescopes under clear, dark skies
    • Available in two sizes to fit 1.25" and 2" threaded telescope eyepieces and diagonals - not recommended for astrophotography
    More Info

    Our Orion Hydrgon-Beta filters help backyard astronomers to see faint and elusive nebulas such as the Horsehead, California, and Cocoon Nebulas. These filters block everything but the hydrogen-beta light that these and some other faint nebulas emit, providing the contrast needed to observe them through a telescope. By isolating the hydrogen-beat spectral line centered at 468.1 nanometers (nm) in a 12nm band-pass while blocking other wavelengths, these filters effectively blacken the background sky, allowing the faint nebula to become clearly defined for visual study. Not recommended for astrophotographic use. 


    Warranty
    Limited Warranty against defects in materials or workmanship for one year from date of purchase. This warranty is for the benefit of the original retail purchaser only. For complete warranty details contact us at 800-447-1001.
