Baader Planetarium Moon & Skyglow Filter

The Baader Planetarium Moon & Skyglow (Neodymium) filter brings an entirely unique approach to contrast enhancement and light pollution reduction. Based on earlier research at Carl Zeiss, Baader has developed a new filter that uses Neodymium glass which filters out a few specific wavelengths from streetlights as well as skyglow from the Moon. The unique spectral characteristics of Neodymium also boost color contrasts by isolating the Red, Green, and Blue regions (so-called RGB enhancement). The result is a filter that leaves natural colors intact, but enhanced.

Lunar and Planetary views are improved in all scopes, reflectors, refractors (APO or Achro). Jupiter's Great Red Spot and ruddy hues of the bands are noticeably enhanced. The Background sky is darkened, and subtle details improved. The filter's high efficiency preserves image brightness, and many Galaxies, Nebulae and Globular Star Clusters are improved due to the reduction of skyglow from artificial lighting.

The high quality of Baader Planetarium filters permits stacking with no image degradation. Achromat owners will find the combination of Moon & Skyglow and the new Fringe Killer filter to be ideal for planetary viewing. The high light throughput and natural coloration will make achromats perform more like an apochromat.

The filter substrate is a special custom melt of Neodymium doped glass, designed for specific transmission characteristics, and made only for Baader Planetarium. In addition to it's unique spectral characteristics, the Baader Moon & Skyglow filter delivers the best possible image sharpness, contrast, and real-world durability.
