Baader Neodymium 31.7mm Filter

 
        

Many companies claim the Neodymium filter being their idea in the meantime – here is the real story:
 
When Baader Planetarium had taken over responsibility for Zeiss Amateur Astro Products Division in 1996, among many other product ideas (which are gradually entering the market…).
 One of the most intriguing was a selective bandpass- filter to cut a good part of light pollution and greatly intensify the H-alpha wavelength of the visual spectrum – working as a whole like an RGB-Intensifier. 
This was achieved with the help of the rare earth element NEODYMIUM, whose effect as astronomical filter never had been tested before.
 The effect is very impressive though, especially if applied on the planets Jupiter and Mars, while at the same time considerably darkening the sky background.
 Many thousands of Neodymium Filters have been distributed since then, being one of the most effectiveand economical tools for the amateur. 

The latest production run features multilayer coatings on both sides, which makes the genuine NEODYMIUM Moon & Skyglow-Filter the brightest in this family of filters. 

Greatly intensifies surface details on Mars, Jupiter and Moon – and enhances many Deep Sky galaxies and nebulae against the background sky.
