This filter enhances the contrast of deep-sky objects while reducing the brightness of the sky background. Achieving this involves a complex transmission characteristic that allows the spectral lines of deep-sky objects to pass while suppressing various sources of light pollution. It effectively diminishes the unwanted sky background, known as "skyglow," caused by oxygen emissions in the atmosphere.
