L'émission se fait sur deux raies se présentant sous la forme d'un doublet, à 671,6 et 673,1 nm. Ce filtre sépare également les émissions de soufre des émissions H-alpha (656,3 nm). Les filtres f\/3.0 de Chroma sont conçus pour minimiser le décalage spectral et mieux conserver leur forme dans un faisceau f\/3.0.\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eDans la boite\u003c\/h3\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\n\u003cli data-mce-fragment=\"1\"\u003e\u003cspan\u003eFiltre Chroma 3nm SII de la taille choisie\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eGarantie et manuels\u003c\/h3\u003e\n\u003cp data-mce-fragment=\"1\"\u003eGarantie à vie Chroma\u003c\/p\u003e","brand":"Chroma","offers":[{"title":"Filtre fileté 1,25\"","offer_id":43974657573093,"sku":"CHR-27067-125","price":805.0,"currency_code":"CAD","in_stock":true},{"title":"Filtre fileté 2\"","offer_id":43974657605861,"sku":"CHR-27067-2","price":1820.0,"currency_code":"CAD","in_stock":true},{"title":"31mm non monté","offer_id":43974657638629,"sku":"CHR-27067-31","price":805.0,"currency_code":"CAD","in_stock":true},{"title":"36mm non monté","offer_id":43974657671397,"sku":"CHR-27067-36","price":1085.0,"currency_code":"CAD","in_stock":true},{"title":"50mm non monté","offer_id":43974657704165,"sku":"CHR-27067-50","price":1750.0,"currency_code":"CAD","in_stock":true},{"title":"50x50mm Carré Non Monté","offer_id":43974657736933,"sku":"CHR-27067-50x50","price":2170.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/chroma-3nm-sii-filter-optimized-for-f2-8-f3-6-27067-astronomy-plus.webp?v=1690489387","url":"https:\/\/istronomyplus.com\/fr\/products\/chroma-3nm-sii-filter-optimized-for-f-2-8-f-3-6-27067","provider":"Astronomy Plus – Telescopes \u0026 Astrophotography Canada","version":"1.0","type":"link"}
