Light pollution filter: When trying to take astronomical photographs from within a city, one of the biggest problems is the "light pollution" caused by bright city lights illuminating the night sky. This filter filters out unnecessary light (light pollution) from city lights and other sources, allowing the light of celestial objects to pass through when observing and photographing nebulae, star clusters, comets, and more. Light pollution filters are designed to cut out only the wavelengths of light emitted by mercury lamps and sodium lamps, which are the source of light pollution.By cutting out the light that causes light pollution, light pollution filters allow you to capture celestial bodies with longer exposure times than usual, even at astronomical observation locations affected by light pollution. The lenses are made of precision-annealed eco-optical glass specifically for glass lenses, and both sides are optically polished to ensure a smooth surface. The multi-layer anti-reflective and double-sided waterproof coating effectively reduces ghosting caused by light reflections, and the waterproof coating also makes it easy to wipe away smudges, fingerprints, and water stains, ensuring a clean, smudge-free lens surface. *K&F CONCEPT is the world's No. 1 brand in terms of lens filter online sales volume among camera-accessory-focused brands.
