It isolates the light of doubly ionized oxygen (O-III) lines (496-501 nm), effectively suppressing all other visible wavelengths. This makes faint objects like the Veil, Ring, Dumbbell, and Orion nebulae much more visible against a blackened background, even under light-polluted skies. It outperforms UHC filters for most planetary nebulae and all types of nebulae with apertures of 10\" or more.\u003c\/p\u003e\n\n\u003cp\u003eFeatures:\n\u003cbr\u003e*   1.25 inch O-III Filter greatly enhances contrast during visual observation of gaseous and planetary nebulae in all sky conditions.\n\u003cbr\u003e*   Allows high-contrast imaging even in areas with strong light pollution.\n\u003cbr\u003e*   Especially useful for large aperture telescopes; allows only Double Ionized Oxygen lines (496nm to 501nm) to pass through at 95 percent.\n\u003cbr\u003e*   Completely blocks virtually all other visible wavelengths of light, optimizing views of nebulas.\n\u003cbr\u003e*   Increases contrast through selective filtration.\n\u003cbr\u003e*   Anti-reflection coated to prevent glaring and ghosting.\n\u003cbr\u003e*   Useful at both light-polluted and dark sky sites.\n\u003cbr\u003e*   Compatible with all 1.25 inch eyepieces.\n\u003cbr\u003e*   Filter made from high-grade glass with dichroic interference and antireflection coatings.\n\u003cbr\u003e*   Each Astromania 1.25inch O-III Filter is individually inspected and proudly inscribed with the percentage of light transmittance of the two O-III emission lines.\u003c\/p\u003e\n\n\u003cp\u003eMaterial: High-grade glass with dichroic interference and antireflection coatings.\n\u003cbr\u003eDimensions: Standard 1.25 inch barrel diameter.\n\u003cbr\u003eUse cases: Visual observation and astrophotography of gaseous and planetary nebulae, particularly beneficial for objects like the Veil, Ring, Dumbbell, and Orion nebulae. Performs well under both light-polluted and dark skies.\u003c\/p\u003e","brand":"Astromania","offers":[{"title":"Default Title","offer_id":42322861686820,"sku":"WBEEAB0141U979O","price":71.59,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0714\/9839\/9780\/files\/71_VANg7S8L.jpg?v=1762523706","url":"https:\/\/electroeshop.com\/products\/astromania-1-25-o-iii-filter-produces-near-photographic-views-of-the-veil-ring-dumbbell-and-orion-nebula-among-many-other","provider":"Electroeshop","version":"1.0","type":"link"}
