About this product

Model:  bneodymium-1

Features enhanced 'Phantom' coatings with UV/IR cut for even better performance. 

Many companies claim the Neodymium filter as 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 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 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.

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


  • Selective contrast enhancing filter, especially suitable for reflector telescopes and true Apochromats. Also effective on smaller economy telescopes that cannot benefit from expensive narrow-band nebula filters due to the huge light-loss involved.
  • Transmits a maximum of light, while blocking unwanted skyglow and many street light emissions.
  • Unique selective blocking feature of the NEODYMIUM element greatly reduces glare, without reducing recognition of important colour and brightness variations.
  • Transmission within the selected wave bands exceeds 95%.
  • 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.
  • Ultrahard and durable Ion-beam hardened coatings, may be cleaned any-time without fear.
  • No image degradation as 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.

If you have never seen the GRS (Great Red Spot) on Jupiter – or surface features on Mars – with this filter you will!

Filter for Mars
Wednesday, 7 October 2020  | 

I bought this filter for observing Mars . It certainly allows some finer detail to be seen and does not change the tone colours. I found it was most effective in my 8 inch Dob, but it also improved the image, though more subtly in my 120 ED frac.

'Swiss Army knife' of filters
Saturday, 30 May 2020  | 

I have the 1.25", (purchased many years ago before FLO was established).
For me it is the 'Swiss Army knife' of filters. This is the 'all in one' or 'Marmite' filter.
Either you love it or hate it.

Not much good for Imaging!
Monday, 11 March 2019  | 

I've had one of these for a few years but until recently I didn't use it much until recently and to be honest its about to be removed from my setup very soon. every image i have taken has a really bad colour cast, which seems to be impossible to balance out. I'll be buying another LPF very soon!

Excellent all around filter
Wednesday, 19 December 2018  | 

Excellent all around filter. Works great visualy: helps on Mars obervation, really makes Jupiter GRS "pop-out" and is an excellent moon filter. It can also be used stacked with the fringe killer as it neutralizes the yellow tint the latter adds to the view. May also be used as a mild light pollution filter in astrophotography applications: I very much prefer it to the UHC-S filter - and other light pollution filters - as it does not affect the color balance and provides better light througput.

To be honest, I can't say that this has made much difference so it stays in its box I'm afraid to say. Still it's well made and well packed.

Very good
Monday, 7 May 2012  | 

Bought the 1.25 version of this filter as I already had a 2" Skywatcher LP filter. To be honest it is difficult to see much difference between the two, but it does what it is supposed to do and you cannot ask more than that.

Not just a light pollution filter
Tuesday, 17 May 2011  | 

After reading many good comments about this filter, I purchased one and have never looked back. I have since sold my 'moon filters', light pollution and coloured planetary filters as the Baader Neodymium Filter (BNF) has effectively replaced them all.
I generally prefer an unfiltered view if possible and especially on the moon to about 50% illumination. However, when the moon is fuller than this it gets quite bright and detail is washed out. Using the BNF creates a grey and contrasty image which appears extremely natural.
I also use the BNF on Jupiter in particular and it does create a colour change but then detail becomes much more visible over a period of observing.
It also does what it says on the tin regarding light pollution and therefore I consider this a 3 into 1 filter - great value indeed!
