1. PRODUCT DESCRIPTION

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.

But that is not all. Baader has enhanced this filter by integrating its proprietary 7-layer Phantom Group and IR blocking coatings as well. The result is improved supression of chromatic aberrations for astrophotography applications.

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 its unique spectral characteristics, unlike most filters, the Baader Moon & Skyglow surfaces are optically polished to deliver the best possible image sharpness and contrast. The high quality of Baader Planetarium filters permits stacking with no image degradation.

The second image above demonstrate the large contrast improvement on Mars.  The image on the left was taken without filtration, while the image on the right was taken through a Moon & Skyglow. The Moon & Skyglow image shows significantly higher contrast and surface features barely visible without the filter. Both images were acquired identically, without any contrast enhancement, and give a very good idea of the planetary contrast improvement that is seen visually.

Note: Occasionally, the product you receive might have a slightly different cosmetic appearance or labeling than what is shown. This can often change from batch to batch according to the whims of the manufacturer. However, you will always receive a brand new, original product as described above.
