This precision-crafted filter blocks the most common wavelengths of unwanted light from sodium-vapour lamps, mercury-vapour lamps, and low colour rendering index streetlights, allowing you to capture clearer, more vibrant images of astronomical objects without interference from artificial light sources. Built from high-quality optical glass with a precision-annealed construction, the filter features NiSi's proprietary multi-layer NANO Coating technology on both surfaces to minimise reflection, reduce ghosting and flare, and deliver exceptional colour fidelity. The nano coating also provides waterproof and oil-resistant properties for convenient maintenance and protection against scratches and abrasions.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePrecision optical glass construction for ultra-high megapixel clarity and sharpness\u003c\/li\u003e\n\u003cli\u003eMulti-layer NANO Coating reduces glare, ghosting and flare with waterproof, oleophobic properties\u003c\/li\u003e\n\u003cli\u003eBlocks common light pollution wavelengths from sodium, mercury, and low CRI LED sources\u003c\/li\u003e\n\u003cli\u003eScratch-resistant coating and easy-clean hydrophobic surface\u003c\/li\u003e\n\u003cli\u003eIdeal for night scenes, astrophotography and dark-sky imaging\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NiSi","offers":[{"title":"Default Title","offer_id":44712380203051,"sku":"170452","price":185.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0588\/9464\/7339\/files\/170452.jpg?v=1786334275","url":"https:\/\/www.teds.com.au\/products\/nisi-49mm-natural-night-filter-light-pollution-filter","provider":"Ted's Cameras","version":"1.0","type":"link"}
