Precision-engineered to counteract light pollution from artificial sources such as mercury vapour, sodium, and low-CRI streetlights, this filter blocks unwanted wavelengths whilst maintaining the natural appearance of the night sky. Constructed from high-quality, precision-annealed optical glass with a finely ground and polished surface, it delivers exceptional sharpness even when paired with today's ultra-high megapixel cameras. The filter features NiSi's exclusive NANO Coating technology on both sides, which reduces reflections to minimise ghosting and flare, and includes a protective oleophobic and hydrophobic layer that repels water, dust, and oil for hassle-free maintenance. Compatible with the NiSi M75 square filter system and other filter holders accommodating 75mm wide filters of 2mm thickness, it delivers approximately one stop of light reduction.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBlocks yellow-tinted light pollution from mercury vapour, sodium, and low-CRI LED streetlights\u003c\/li\u003e\n\u003cli\u003ePrecision-annealed optical glass construction ensures maximum sharpness and clarity\u003c\/li\u003e\n\u003cli\u003eDouble-sided NANO Coating reduces flare and ghosting with ultra-low reflection\u003c\/li\u003e\n\u003cli\u003eWaterproof and oil-resistant coating for effortless cleaning and durability\u003c\/li\u003e\n\u003cli\u003eCompatible with NiSi M75 filter system and square filter holders\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NiSi","offers":[{"title":"Default Title","offer_id":44712392228907,"sku":"170491","price":135.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0588\/9464\/7339\/files\/170491.jpg?v=1786344868","url":"https:\/\/www.teds.com.au\/products\/nisi-75x80mm-natural-night-filter-light-pollution-filter","provider":"Ted's Cameras","version":"1.0","type":"link"}
