(#05658, $45, new $79.95) + $7 shipping. Excellent condition.
Takes advantage of SCT visual back's threads and works with both 1.25" and 2" accessories and eyepieces.
From Orion: 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.
