The best visual and photographic filter for contrast enhancement for all telescopes, without loss of image brightness!
The effect of the element neodymium as filter material is very impressive. When added to optical glass, it enhances contrast, enhances the red colour in the image (especially with Mars and Jupiter) and it darkens the spectral region which is particularly marked by street lamp light, which is the biggest contributor to the nightly “Skyglow”.

The Baader Moon & Skyglow filter 1.25″ greatly enhances visual contrast for lunar & planetary work by removing most streetlights, skyglow and IR (for CCD imaging).
Drastically improved contrast for all reflector telescopes, without loss of brightness!
Greatly 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 all reflector type telescopes and true Apochromates (Economy refrator owners might consider the Contrast-Booster Filter instead, featuring an additional dielectric UV-blocker, to eliminate blue part of the spectrum.)
Especially effective on small economy telescopes which cannot benefit from expensive narrow-band nebula filters due to the hughe light-loss involved.
Transmission within the selected wave bands exceeds 95%.
Planeoptically polished! Retains full image resolution – even at highest magnification, way above 200 times, or during eyepiece protection work – even in front of a binocular viewer.
