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.
