filters. Bright, light-polluted skies appear much darker, and the contrast
between object and sky is improved significantly. This contrast-enhancement
effect is particularly apparent on nebulas. Unlike stars, emission nebulas give
off light in a very narrow range of wavelengths. Moon and SkyGlow filters allow

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
