Primarily developed to filter interfering light from streetlamps and the scattered atmospheric light that they and the moon can cause, the 1.25" Alpine Astronomical Baader Neodymium Moon & Skyglow Filter can be used by itself or stacked with other types of filters for both visual observation and astrophotography. With this filter, red and blue colors are strengthened without significant dimming of the view, presenting natural and enhanced colors without tinting.

Planetary and lunar views are improved when used with reflectors and apochromatic or achromatic refractors. Jupiter's Great Red Spot and ruddy hues of the bands are noticeably enhanced, and contrast of Martian surface features are significantly boosted. Its high transmittance preserves image brightness and galaxies, nebulae, and globular star clusters are improved due to the reduction of skyglow and light pollution. The filter also benefits from UV/IR luminance coatings which make the filter ideal for astrophotography through DSLRs or CCD imagers that are sensitive to wavelengths outside the visual spectrum, which can often cause ghosting.
