This extra narrowband SII CCD 7nm filter is designed for nebula observation allowing 12nm bandwidth of light centered on a wavelength of 672nm through, and reducing the transmission of certain wavelengths of light, specifically those produced by artificial light including mercury vapor, high and low pressure sodium vapor lights, and the natural light caused by neutral oxygen emission in our atmosphere (i.e., skyglow). The filter only lets the light of the ionized sulfur pass and blocks the rest of the visual spectrum.\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cimg alt=\"\" src=\"https:\/\/www.deepspaceproducts.com\/uimages\/pegasus\/Filter_narrowband_graph.png?width=700\" width=\"511\" height=\"297\"\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003ch3\u003eTechnical Specification\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ctable dir=\"ltr\" cellspacing=\"0\" cellpadding=\"0\" border=\"1\"\u003e\n\u003ccolgroup\u003e \u003ccol width=\"194\"\u003e \u003ccol width=\"199\"\u003e \u003c\/colgroup\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"2\" rowspan=\"1\" data-sheets-value='{\"1\":2,\"2\":\"Specifications\"}'\u003eSpecifications\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-sheets-value='{\"1\":2,\"2\":\"Filter Size:\"}'\u003eFilter Size:\u003c\/td\u003e\n\u003ctd data-sheets-value='{\"1\":2,\"2\":\"2 inch\"}'\u003e2 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-sheets-value='{\"1\":2,\"2\":\"Polish:\"}'\u003ePolish:\u003c\/td\u003e\n\u003ctd data-sheets-value='{\"1\":2,\"2\":\"1\/4 wavefront, Parfocal\"}'\u003e1\/4 wavefront, Parfocal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-sheets-value='{\"1\":2,\"2\":\"Transmission Range: \"}'\u003eTransmission Range:\u003c\/td\u003e\n\u003ctd data-sheets-value='{\"1\":2,\"2\":\"T \u0026gt; 80%, 627 nm, 7nm FWHM\"}' style=\"box-sizing: border-box; border-bottom: 1px solid #ececec; font-size: 0.9em; line-height: 1.3; padding: 0.5em 0px 0.5em 0.5em; text-align: left; color: #666666;\"\u003eT \u0026gt; 80%, 627 nm, 7nm FWHM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-sheets-value='{\"1\":2,\"2\":\"Coatings: \"}'\u003eCoatings:\u003c\/td\u003e\n\u003ctd data-sheets-value='{\"1\":2,\"2\":\"Multilayer Anti-reflection\"}'\u003eMultilayer Anti-reflection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-sheets-value='{\"1\":2,\"2\":\"Type:\"}'\u003eType:\u003c\/td\u003e\n\u003ctd data-sheets-value='{\"1\":2,\"2\":\"Narrowband (7nm\"}'\u003eNarrowband (7nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-sheets-value='{\"1\":2,\"2\":\"Shape:\"}'\u003eShape:\u003c\/td\u003e\n\u003ctd data-sheets-value='{\"1\":2,\"2\":\"Round\"}'\u003eRound\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-sheets-value='{\"1\":2,\"2\":\"Thickness: \"}'\u003eThickness:\u003c\/td\u003e\n\u003ctd data-sheets-value='{\"1\":2,\"2\":\"5mm (filter) + 2.5mm (thread)\"}'\u003e5mm (filter) + 2.5mm (thread)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-sheets-value='{\"1\":2,\"2\":\"Thread: \"}'\u003eThread:\u003c\/td\u003e\n\u003ctd data-sheets-value='{\"1\":2,\"2\":\"M48, 0.75 pitch\"}'\u003eM48, 0.75 pitch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIn the Box\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cp\u003e\u003cspan mce-data-marked=\"1\"\u003eFilter\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eManual \u0026amp; Warranty\u003c\/h3\u003e\n\u003cp\u003ePegasus 1-Year Warranty\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\u003cbr\u003e\u003c\/div\u003e","brand":"Pegasus","offers":[{"title":"Default Title","offer_id":51750858031337,"sku":"rlx1787937127206","price":183.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/6964\/9129\/files\/pegasus-astro-photographic-filter---sii-2-mounted-filter-peg-fltr-2m-s2_1.webp?v=1787937131","url":"https:\/\/www.sandalcove.shop\/products\/pegasus-astro-photographic-filter-sii-2-mounted-filter-peg-fltr-2m-s2","provider":"My Store","version":"1.0","type":"link"}
