On larger apertures, where the Moon's brightness is even more intense, a lower-transmission filter (e.g. 13%) may be preferable.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\u003cth\u003eConnection\u003c\/th\u003e\u003ctd\u003e1.25\" (31.8mm), standard eyepiece thread\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eLight transmission\u003c\/th\u003e\u003ctd\u003e30% (ND 0.5)\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eHousing material\u003c\/th\u003e\u003ctd\u003eAluminium\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eOptical coating\u003c\/th\u003e\u003ctd\u003eMulti-layer\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eSuitable for telescopes up to\u003c\/th\u003e\u003ctd\u003e200mm aperture\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eCase\u003c\/th\u003e\u003ctd\u003eProtective plastic case, included\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\n\u003ch2\u003eWho it's recommended for\u003c\/h2\u003e\n\u003cp\u003eFor anyone who regularly observes the Moon and planets and wants to reduce glare during full moon phases while keeping a natural, high-contrast image — an affordable yet solidly built accessory.\u003c\/p\u003e","brand":"Omegon","offers":[{"title":"Default Title","offer_id":57998208106827,"sku":"OM5085","price":19.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0886\/1981\/1147\/files\/Omegon-Filtro-lunare-Premium-1-25.jpg?v=1785487483","url":"https:\/\/adriasky.it\/en\/products\/omegon-moon-filter-125-premium","provider":"Adriasky","version":"1.0","type":"link"}
