THIS IS AN EX DISPLAY FILTER. IT IS AS NEW BUT THE BOX HAS BEEN OPENED

Many companies claim the Neodymium filter was their idea – 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 an astronomical filter had never been tested before. The effect was very impressive, 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 effective and 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. This greatly intensifies surface details on Mars, Jupiter and the Moon. In addition it enhances many Deep Sky objects against the background sky. This selective contrast enhancing filter is especially suitable for all reflector type telescopes and true Apochromates. The filter transmits the maximum of light, while blocking unwanted skyglow and many street light emissions. It is especially effective on small economy telescopes which cannot benefit from expensive narrow-band nebula filters due to the huge light-loss involved. The unique selective blocking feature of the NEODYMIUM element greatly reduces glare, without reducing recognition of important color and brightness variations. Transmission within the selected wave bands exceeds 95%.

The 1.25" size fits all standard filter threads, and can be combined with an UV/IR-Cut Filter for all CCD and digital camera work. This combination works extremely well due to cutting out all unfocused light – an absolute MUST for digital imaging.

The filter is planeoptically polished and retains full image resolution – even at high magnifications above 200 times, or during eyepiece projection work – even in front of a binocular viewer! Ultrahard and durable Ion-beam hardened coatings, may be cleaned anytime without fear. No image degradation as with `flame polished` filters.
