BAADER Neodymium Moon & Skyglow Filter

Features enhanced 'Phantom' coatings with UV/IR cut for even better performance. Intensifies surface details on Mars, Jupiter and Moon – and enhances many Deep Sky galaxies and nebulae against the background sky.

Features:

• 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.
• High light transmission, while blocking unwanted skyglow and many street light emissions.
• The unique selective blocking feature of the NEODYMIUM element significantly 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 the 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 anytime without fear.
• No image degradation as with 'flame polished' filters.
• Non-vignetting filter cells, with a larger aperture than competing designs and a CNC-machined 'crown' for ease of handling and attachment.

The latest production run features multilayer coatings on both sides, making this genuine Neodymium Moon & Skyglow-Filter the brightest in its class.

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

Many companies claim the Neodymium filter as their idea – here is the real story: When Baader Planetarium took 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. The performance is impressive, especially when observing Jupiter and Mars, while simultaneously darkening the sky background.
