This filter blocks the most common wavelengths of light pollution from mercury vapour, sodium, and low CRI streetlights, allowing your camera to capture clearer, more authentic night scenes. Constructed from high-quality, precision annealed optical glass with a finely ground and polished surface, the filter features NiSi's unique multi-layer NANO Coating technology with waterproof and oil-resistant properties. The double-sided coating reduces reflection to minimise ghosting and flare, ensuring exceptional image clarity even with modern high-megapixel cameras. Approximately 1 stop of light reduction.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSpecifically designed for night photography and astrophotography\u003c\/li\u003e\n\u003cli\u003eBlocks wavelengths from common light pollution sources for clearer night skies\u003c\/li\u003e\n\u003cli\u003ePremium optical glass construction with multi-layer NANO Coating technology\u003c\/li\u003e\n\u003cli\u003eWaterproof and oil-resistant nano coating reduces ghosting and flare\u003c\/li\u003e\n\u003cli\u003e40.5mm thread size for easy attachment to compatible lenses\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NiSi","offers":[{"title":"Default Title","offer_id":44712379875371,"sku":"170450","price":169.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0588\/9464\/7339\/files\/170450.jpg?v=1786334265","url":"https:\/\/www.teds.com.au\/products\/nisi-40-5mm-natural-night-filter-light-pollution-filter","provider":"Ted's Cameras","version":"1.0","type":"link"}
