  • 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.
