American Nebula). Its medium 35nm FWHM bandwidth is ideal for interline CCD cameras ( like SBIG ST-2000\/STL11000). The lower sensitivity of interline transfer CCDs benefits from the more efficient 35nm FWHM. The sharp bandpass and \u0026gt; 90% high efficiency coatings make the Baader H-Alpha filter superior to the common colored-glass based filters, all at a reasonable price.\u003cbr\u003e\u003cbr\u003eThe Baader H-Alpha filter shares the same outstanding features as all the other Baader imaging filters. Unmatched optical quality, and high efficiency hardened multicoatings result in the sharpest and highest contrast images possible.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications \u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eMANUFACTURER\u003c\/th\u003e\n\u003ctd\u003eBaader Planetarium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSKU (#)\u003c\/th\u003e\n\u003ctd\u003e2458381\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eEAN CODE\u003c\/th\u003e\n\u003ctd\u003e4047825009456\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWEIGHT (KG)\u003c\/th\u003e\n\u003ctd\u003e0.059\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCOLOUR\u003c\/th\u003e\n\u003ctd\u003eBlack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTRANSMISSION RANGE\u003c\/th\u003e\n\u003ctd\u003eH-alpha\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFILTER THICKNESS (WITHOUT CELL)\u003c\/th\u003e\n\u003ctd\u003e2 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHBW (HALFBANDWIDTH)\u003c\/th\u003e\n\u003ctd\u003e35nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCWL (CENTRAL WAVELENGTH)\u003c\/th\u003e\n\u003ctd\u003e656,3 nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAR-COATING\u003c\/th\u003e\n\u003ctd\u003edielectrically coated, planeoptically polished\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFILTER SIZE\u003c\/th\u003e\n\u003ctd\u003e1 25 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFILTER USAGE\u003c\/th\u003e\n\u003ctd\u003eH-alpha, Interline-CCD, IR-Cut\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFILTER MOUNTED\u003c\/th\u003e\n\u003ctd\u003eMounted (LPFC 6mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTYPE OF FILTER\u003c\/th\u003e\n\u003ctd\u003eNarrowband\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSINGLE OR SET?\u003c\/th\u003e\n\u003ctd\u003eSingle Filter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFILTER SHAPE\u003c\/th\u003e\n\u003ctd\u003eround\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cp\u003e 1.25'' H-alpha 35nm CCF Filter - USED\u003c\/p\u003e","brand":"Baader Planetarium","offers":[{"title":"Default Title","offer_id":52145476239589,"sku":"BAA-2458381-U","price":40.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/20260822_165803.jpg?v=1787432394","url":"https:\/\/astronomyplus.com\/products\/baader-1-25-h-alpha-35nm-ccf-filter-used-2458381-u","provider":"Astronomy Plus – Telescopes \u0026 Astrophotography Canada","version":"1.0","type":"link"}
