The Baader Planetarium Moon & Skyglow (Neodymium) filter brings an entirely unique approach to contrast enhancement 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 Blue regions (so-called RGB enhancement). The result is a filter that leaves natural colors intact but enhanced.Lunar Planetary views are improved in all scopes reflectors refractors (APO Achro). Jupiter's Great Red Spot ruddy hues of the bands are noticeably enhanced. The Background sky is darkened subtle details improved. The filter's high efficiency preserves image brightness many Galaxies Nebulae Globular Star Clusters are improved due to the reduction of skyglow from artificial lighting.The high quality of Baader Planetarium filters permits stacking no image degradation. Achromat owners will find the bination of Moon & Skyglow the new Fringe Killer filter to be ideal for planetary viewing. The high light throughput 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 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 real-world durability.
