Average OD5 blocks 99.999% stray light for clean images. Ideal for Astrophotography -- Superior for capturing clear, high-contrast deep-sky images even under light-polluted skies.\u003cbr\u003e- Minimal Halo Imaging: Anti-glare coating process effectively reduces halo and glare interference, ensuring the purity and delicacy of the image, especially suitable for photographing the starry sky and deep-sky celestial bodies.\u003cbr\u003e- Full-Frame Compatible (only 2 inches applicable): Full-frame design ensures no vignetting, broad field of view, and accurate color reproduction. It improves image uniformity, clarity, and contrast, ideal for high-res deep-sky observations, maintaining consistent quality across the frame.\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Included:\u003c\/b\u003e\u003cbr\u003e- 1 x Filter\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 960px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/102450\/102450-01.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 960px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/102450\/102450-02.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 960px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/102450\/102450-03.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 960px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/102450\/102450-04.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 960px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/102450\/102450-05.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 960px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/102450\/102450-06.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 960px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/102450\/102450-07.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 960px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/102450\/102450-08.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 960px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/102450\/102450-09.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 960px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/102450\/102450-10.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 960px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/102450\/102450-11.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 960px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/102450\/102450-12.jpg\"\u003e\u003c\/p\u003e\u003cp\u003e\u003cimg style=\"width: 960px;\" src=\"https:\/\/www.comseek.com\/image\/catalog\/102450\/102450-13.jpg\"\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"SVBONY","offers":[{"title":"3nm\/1.25-Inch \/ H-Alpha \u0026OIII","offer_id":47718015402220,"sku":"102450","price":112.0,"currency_code":"USD","in_stock":true},{"title":"3nm\/2-Inch \/ H-Alpha \u0026OIII","offer_id":47718015467756,"sku":"102451","price":272.0,"currency_code":"USD","in_stock":true},{"title":"7nm\/1.25-Inch \/ H-Alpha \u0026OIII","offer_id":47718015533292,"sku":"102452","price":56.0,"currency_code":"USD","in_stock":true},{"title":"7nm\/1.25-Inch \/ SII \u0026OIII","offer_id":47718015566060,"sku":"102454","price":260.0,"currency_code":"USD","in_stock":true},{"title":"7nm\/2-Inch \/ H-Alpha \u0026OIII","offer_id":47718015598828,"sku":"102453","price":128.0,"currency_code":"USD","in_stock":true},{"title":"7nm\/2-Inch \/ SII \u0026OIII","offer_id":47718015631596,"sku":"102455","price":416.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0755\/9669\/3740\/files\/1779931021-1.jpg?v=1780022378","url":"https:\/\/teseek.com\/es\/products\/svbony-sv220-multi-layer-coating-h-alpha-amp-oiii-dual-narrowband-filter-for-astronomical-telescope-3nm-1-25-inch","provider":"TeSeek Official","version":"1.0","type":"link"}
