The 12nm version is more suitable for small telescopes or color sensors. With the 7nm filter and B\/W CCD sensors, you can capture the faintest details of nebulae even under polluted skies; obviously, under a good sky, the result will be even more spectacular!\u003c\/p\u003e\n\n\u003ch2 style=\"font-size:20px;margin-top:30px;\"\u003eMain features\u003c\/h2\u003e\n\n\u003cp\u003eOptolong quality for a reliable and satisfying observation experience.\u003c\/p\u003e\n\n\u003cul style=\"padding-left:20px;\"\u003e\u003cli\u003eFilter diameter: 2\"\u003c\/li\u003e\u003c\/ul\u003e\n\n\u003ch2 style=\"font-size:20px;margin-top:30px;\"\u003eMain technical specifications\u003c\/h2\u003e\n\n\u003ctable style=\"width:100%;border-collapse:collapse;margin-top:10px;\"\u003e\u003ctbody\u003e\n\n\u003ctr\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003eBrand\u003c\/td\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003eOptolong\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003eModel\u003c\/td\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003eOptolong H-alpha 7nm 2\" Filter\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003eType\u003c\/td\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003e2-inch Filters – 50.8mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003eFilter diameter\u003c\/td\u003e\n\n\u003ctd style=\"padding:8px;border:1px solid #ccc;\"\u003e2\"\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/tbody\u003e\u003c\/table\u003e\n\n\u003cdiv style=\"background-color:#f0f8ff;padding:15px;margin-top:30px;border-left:4px solid #007acc;\"\u003e\n\n\u003cstrong\u003eFree shipping\u003c\/strong\u003e\u003cbr\u003eTake advantage of free shipping throughout Italy for orders over €199.99!\u003c\/div\u003e\n\n\n\u003c\/div\u003e","brand":"Optolong","offers":[{"title":"Default Title","offer_id":51121344053464,"sku":"HA7-2","price":174.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/0722\/6072\/files\/fc1a6793a6509a23bf8ee46d95cb0636.jpg?v=1764083378","url":"https:\/\/www.giordanoastronomia.it\/en\/products\/optolong-filtro-h-alpha-7nm-2-pol","provider":"Giordano Astronomia","version":"1.0","type":"link"}
