The 2" Baader Planetarium Moon & Skyglow (Neodymium) filter is useful in filter slides or when placed in the nosepiece of a 2-inc star diagonal. Most eyepieces capable of the magnification needed for planetary observing are offered only in 1.25-inch format. Given the frequent need to change eyepieces to hunt for the highest practical magnification on any given night, use of a 2-inch filter placed in a filter slide (Dobsonian telescopes) or the nosepiece of a 2-inch refractor style diagonal (refractors and SCTs) can be quite convenient. This allows you to quickly change eyepieces without having to remove and replace the filter.

The Baader Planetarium Moon & Skyglow (Neodymium) filter brings an entirely unique approach to planetary 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 mostly intact, but significantly enhanced.

Planetary and Lunar 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, and contrast of Martian surface features significantly boosted. 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 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, unlike most filters, the Baader Moon & Skyglow surfaces are optically polished to deliver the best possible image sharpness and contrast.
