Unlike stars, emission nebulas give off light in a very narrow range of wavelengths. SkyGlow broadband filters allow maximum transmission of the important wavelengths of hydrogen-alpha, hydrogen-beta and doubly ionized oxygen, the light bands most commonly emitted by nebulas. Views of galaxies and star clusters are also enhanced, although these objects don’t show as dramatic an improvement as nebulas. (They emit a broad spectrum, so their brightness is reduced along with light pollution.) An unexpected advantage of the SkyGlow filter is its improvement of planetary images, particularly of Jupiter, especially in conjunction with a color filter. Without any filters, this bright planet's cloud bands frequently appear only as faint smears. Pop in the filters, and distinct banding, knottings, and festoons appear, and the edges of Jupiter's disk stand out crisply. Orion SkyGlow Astronomy Filter Features...
