Light pollution is waging war
on amateur astronomy. But don't surrender — fight back with this Orion SkyGlow
broadband filter!
This 1.25" SkyGlow Broadband
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.
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!
