It's excellent for photographing star-forming regions and planetary nebulae from light-polluted cities, but its effect is also noticeable in rural areas. This filter isolates OIII emissions and highlights the brilliant red structures of nebulae. Famous examples include the Orion Nebula and the Lagoon Nebula.\u003c\/p\u003e\n\u003cp\u003eDue to its narrow FWHM of only 6 nm and high transmission in the singly ionized oxygen region, the contrast is further enhanced compared to wider band filters.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Omegon","offers":[{"title":"Default Title","offer_id":53581587054935,"sku":"60113","price":156.2,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/60113_1.jpg?v=1779016100","url":"https:\/\/astrotelescopios.com\/en-efta\/products\/filtro-pro-oiii-7nm-filter-1-25","provider":"Astro Telescopios","version":"1.0","type":"link"}
