Baader Planetarium 1.25" Neodymium Filter


Baader Planetarium 1.25" Neodymium filter.

The Neodymium filter will improve views of the Moont, planets, and deep sky objects and is suitable for all sizes of telescope, thanks to its high light transmission and quality multi-coatings, if you only ever buy one filter for your telescope this is the perfect choice.

A premium selective bandpass-filter to cut a major part of light pollution and greatly intensify the H-Alpha wavelength of the visual spectrum working as a whole like an RGB-intensifier.  This is achieved with the use of the rare earth element Neodymium, whose effect as astronomical filter is unique.  The effect is 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 being one of the most effective and economical tools for the amateur astronomer.

Drastically improves contrast for all reflector telescopes, without loss of brightness!  The latest production run features multi-layer 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 the Moon, and enhances many Deep Sky galaxies and nebulae against the background sky.


  • Selective contrast enhancing filter, especially suitable for all reflector type telescopes and true Apochromats.
  • Transmitts a maximum of light, while blocking unwanted skyglow and many street light emissions.
  • Especially effective on small economy telescopes which cannot benefit from expensive narrow-band nebula filters due to the huge light-loss involved.
  • 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 exceed 95%.
  • Fits all standard filter threads in 1.25" eyepieces, barlows and accessories.
  • Can be combined with UV/IR Cut-Filter for all CCD and digital camera word.  This combination works extremely well due to cutting all unfocused light, an absolute must for digital imaging.
  • Planeoptically polished!  Retains full image resolution even at highest magnification, way above 200x, or during eyepiece projection work, even in front of a binocular viewer.
  • Phantom coating group - Ultrahard and durable Ion-beam hardened coatings, may be cleaned anytime without fear.
  • No image degradation is with "flame polished" filters.
  • Non-vignetting filter cells, larger in aperture than any competing design, featuring a CNC milled "crown" for ease of handling and attachment.
