At wavelengths longer than 650nm, transmittance is 90% or above. This convenient filter only allows wavelengths above 650nm through, which means it blocks a large part of the scattered light and also blocks the light from artificial mercury and sodium-vapour lamps.

Product Description & Reviews

The Night Sky Hydrogen-Alpha Filters are narrowband filters with a 50% transition from blocking to passing at about 640nm. At wavelengths longer than 650nm, transmittance is 90% or above. This convenient filter only allows wavelengths above 650nm through, which means it blocks a large part of the scattered light and also blocks the light from artificial mercury and sodium-vapour lamps. The filter is used as an extreme anti light-pollution filter, and for contrast-enhancement of emission nebulae and other astronomical objects bright in the infrared. The 1.25" Night Sky Hydrogen-Alpha Filter, threads into the nose-piece of industry-standard 1.25" Digital Imagers. The Astromania H-Alpha cut-off filter enhances the contrast between object and sky, allowing you to take good quality images even under urban skies.

Features & Highlights

  • A filter with incredible light pollution cut off characteristics.
  • The new H-Alpha passfilter enables high-contrast deep sky images of H-II regions.
  • The H-Alpha filter shares the same outstanding features as all the other Astromania imaging filters.
  • Unmatched optical quality, and high efficiency hardened multicoatings result in the sharpest and highest contrast images possible.
  • The filter is used as an extreme anti light-pollution filter, and for contrast-enhancement of emission nebulae and other astronomical objects bright in the infrared.
