Orion - SkyGlow Filter, SCT

An Effective Weapon for Combatting Bright Skies, Bad Contrast

SkyGlow Broadband Filter, Schmidt Cassegrain

    * The SkyGlow filter enhances deep-sky observing in moderately light-polluted skies
    * It blocks the most common wavelengths of light pollution for increased contrast and better views
    * SkyGlow improves the views of nebulas, galaxies and clusters
    * Threads on to rear cell of Schmidt-Cassegrain telescopes

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

This SkyGlow Broadband Filter 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
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!
