An Effective Weapon for Combatting Bright Skies, Bad Contrast 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 significantly enhanced, particularly emission nebulas like the Orion and Lagoon. Views of galaxies and clusters are also improved.

This was purchased in July 2002, I am getting rid of all 2" Accessories. $75 w/ Free shipping. Prefer PayPal or Money Order. Will ship to continental US only.
