A great choice for observations of supernova remnants and other nebulae that glow in O-III emission light. Other types of objects that glow in all parts of the visible spectrum (e.g. galaxies) are reduced visibly, but some normally invisible regions of nebulae are clearly visible. This filter fits all standard 1.25-inch eyepieces and filter wheels.\u003c\/p\u003e","brand":"Explore Scientific","offers":[{"title":"Default Title","offer_id":16329031489,"sku":"EXP-310205","price":96.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/products\/0310205_M.jpg?v=1776458936","url":"https:\/\/khanscope.com\/en-fr\/products\/explore-scientific-o-iii-nebula-filter-310205","provider":"Khan Scope Centre","version":"1.0","type":"link"}
