High quality anodized aluminium, optical glass variable polarising filters for light reduction
In astronomy, polarising filters are used in various situations. A common application is the observation of reflection nebulae, where the light from stars is scattered by dust and gas clouds. A polarising filter can help increase the contrast between the nebula and the surrounding sky by reducing the scattered polarised light.
