2in. Orion SkyGlow Broadband Telescope Filter
Light pollution is waging war on amateur astronomy. But don't surrender - fight back with this Orion SkyGlow broadband telescope filter! This 2" SkyGlow Broadband telescope filter is an advanced multilayer "interference" filter that blocks the most common wavelengths of light pollution while passing desirable wavelengths with very little attenuation, yielding dramatically better deep-sky views. It features improved blocking of mercury-vapor light and higher transmission at critical hydrogen-alpha and hydrogen-beta lines than competing filters. Bright, light-polluted skies appear much darker, and the contrast between object and sky is improved significantly.
Enhances All Objects
This contrast-enhancement effect is particularly apparent on nebulas. Unlike stars, emission nebulas give off light in a very narrow range of wavelengths. Orion SkyGlow telescope filters allow maximum transmission of the important wavelengths of hydrogen-alpha, hydrogen-beta, and doubly ionized oxygen-the ones most commonly emitted by nebulas. Views of galaxies and star clusters are also enhanced, although not as much. Why suffer under light-polluted skies any longer? Buy your Orion SkyGlow light-pollution filter today. It really works!
