Moon & Skyglow Filter

Drastically improved contrast for allreflector telescopes, without loss of brightness! This filter goes back upon a development of Carl Zeiss Jena – to provide proper
credit after all!
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…), oneof the most intriguing was a selective bandpassfilter to cut a good part of light pollution and greatly
intensify the H-α wavelength of the visual spectrum– working as a whole like an RGB-Intensifier.
This was achieved with the help of the rareearth 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 atthe same time considerably darkening the sky background. Many thousands of Neodymium Filters havebeen distributed since then, being one of the mosteffective, while priceworthy 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, Jupiterand Moon – and enhances many Deep Sky galaxies and nebulae against the background sky.

might consider the Contrast-Booster Filter
instead, featuring an additional dielectric UVblocker, to eliminate the unfocused blue part ofthe spectrum.)Transmitts a maximum of light (– after all LIGHT
is “the hottest commodity” in this astronomybusiness...), while blocking unwanted skyglow
and many street light emissions.
Especially effective on small economy telescopes
which cannot benefit from expensive narrowband nebula filters due to the huge light-loss
involved.
Unique selective blocking feature of theNEODYMIUM element greatly reduces glare,
without reducing recognition of important colorand brightness variations.
Transmission within the selected wave bands
exceeds 95%.
Fits all standard filter threads,
Longs to be combined with an UV/IR-Cut-Filter
for all CCD and digital camera work.
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 200 times, or during eyepiece projection
work – even in front of a binocular viewer.
