{"product_id":"explore-scientific-2-o-iii-filtro-de-nebulosa","title":"EXPLORE SCIENTIFIC 2\" O-III Nebular Filter","description":"One of the most significant obstacles to exploring the night sky is the brightness of the night sky caused by artificial lights, such as streetlights. The night sky is not very dark in the vicinity of towns or cities, which reduces the visibility of objects beyond massive solar systems. Depending on the type of celestial object, it is possible to drastically increase the contrast by blocking annoying artificial light. The Explore Scientific UHC filter uses a characteristic property of artificial lighting. Streetlights and lamps glow in special colors - the typical colors of high-pressure or mercury lamps. The Explore Scientific CLS nebular filter blocks these colors and, therefore, increases the contrast - the light from celestial objects can pass through the filter. The result is astonishing: suddenly, objects are visible in locations that were previously completely empty without filters. In suburban skies, for example, the great galaxy M101, the Veil Nebula Ngc 6992, or even the bright Dumbbell Nebula M27, are not clearly visible. By using this filter, one can see the nebulae and their structures. Mandatory for every observer. \u003cbr\u003e\u003cbr\u003eExplore Scientific nebula filters come with an individual test certificate - the guarantee of receiving a high-quality filter.","brand":"Explore Scientific","offers":[{"title":"Default Title","offer_id":52791594975575,"sku":"310200","price":129.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/0310200.jpg?v=1770989666","url":"https:\/\/astrotelescopios.com\/en-us\/products\/explore-scientific-2-o-iii-filtro-de-nebulosa","provider":"Astro Telescopios","version":"1.0","type":"link"}
