Features
- Our SkyGlow is an advanced multilayer "interference" filter designed to enhance deep-sky observing in moderately light-polluted skies
- It blocks the most common wavelengths of light pollution - predominantly produced by mercury vapor lamps - and allows higher transmission of critical hydrogen-alpha and hydrogen-beta lines
- Bright, light-polluted skies appear much darker in the field of view and contrast is significantly enhanced
- Available in 1.25" and 2"and as a thread-on for rear cells of Schmidt-Cassegrains.
Light pollution is waging war on amateur astronomy. But don't surrender — fight back with an Orion SkyGlow broadband filter!
It's 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.
SkyGlow filters feature 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!
