2" SkyGlow Broadband Filter
[OR05659]

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.
