Orion SkyGlow Broadband Filter for Schmidt-Cassegrain Telescopes

Light pollution is waging war on amateur astronomy. But don't surrender fight back with this Orion SkyGlow broadband filter!

This SkyGlow Broadband Filterr for Schmidt-Cassegrain telescopes 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 betterdeep-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 skyis 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. SkyGlow 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? Order your SkyGlow light-pollution filter today. It really works!
