SkyGlow Broadband Light-Pollution Filter
Now save $15 on this great filter!The Orion 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, particularly for emission nebulas like the Orion and Lagoon. Views of galaxies and clusters are also improved. 1.25" size attaches to standard eyepieces.
