The result is extreme contrast between the black sky background and the faint photons of OIII light needed for detailed views of the Veil, Ring, Dumbbell, Crescent and Orion nebulae, among other objects.\u003cbr\u003e\u003cbr\u003eEach filter has an ultra hard, vacuum-deposited coating carefully designed to block all of the visual spectrum ranging from 400 to 700nm This eliminates the un-natural colored halos surrounding bright stars common with O III filters of less sophisticated coating technology.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe 2\" OIII narrowband filter isolates the two doubly-ionized oxygen lines (496 and 501 nm lines)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eFilter has ultra-hard, vacuum-deposited coating\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eEliminates un-natural colored halos surrounding bright stars\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eIn the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCelestron 2\" Oxygen III Narrowband Filter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eWarranty \u0026amp; Manuals\u003cbr data-mce-fragment=\"1\"\u003e\n\u003c\/h3\u003e\n\u003cp data-mce-fragment=\"1\"\u003e2-Year Warranty\u003c\/p\u003e","brand":"Celestron","offers":[{"title":"Default Title","offer_id":44958383898717,"sku":"rqy1787936992673","price":51.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0690\/2684\/0669\/files\/celestron-2-oxygen-iii-narrowband-filter-93624_1.jpg?v=1787937020","url":"https:\/\/www.cedarstorehouse.shop\/products\/celestron-2-oxygen-iii-narrowband-filter-93624","provider":"My Store","version":"1.0","type":"link"}
