{"product_id":"ocular-explore-scientific-68-ar-34mm-2","title":"EXPLORE SCIENTIFIC 68° Ar 34mm (2\") Eyepiece","description":"With the introduction of the \u003cb\u003e68° Series\u003c\/b\u003e, we are pleased to announce two significant improvements in \u003cb\u003eeyepiece\u003c\/b\u003e manufacturing, the first being 15 layers of Enhanced Multi-layer Deposition (EMD™) coatings on all glass-to-air surfaces for maximum contrast, and the waterproofing of the eyepiece with the use of argon gas purging instead of standard nitrogen gas. Although nitrogen is a good option that will last for many years, argon is a larger molecule that maintains its protective properties over a wide range of temperatures, and is even more resistant to diffusion, thus providing broad protection against water to the eyepiece body.\u003cbr\u003e\n\u003cbr\u003e\nThrough computer-optimized design, careful selection of optical lenses, and multi-layer deposition coatings, Explore Scientific 68° Series eyepieces provide a large eye relief and ensure high image correction, a flat field, and high contrast across the entire image field. An excellent choice for those who do long visual studies of detail with subtle brightness variations, and for those who need to wear glasses while observing.\u003cbr\u003e\n\u003cbr\u003e\nThe 68° Series eyepieces are fully EMD (Enhanced Multi-Layer Deposition) coated and edge-darkened to produce superior contrast.","brand":"Explore Scientific","offers":[{"title":"Default Title","offer_id":52791588553047,"sku":"218634","price":338.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/6198\/6860\/files\/0218634_M_2_v0416.jpg?v=1770989629","url":"https:\/\/astrotelescopios.com\/en-us\/products\/ocular-explore-scientific-68-ar-34mm-2","provider":"Astro Telescopios","version":"1.0","type":"link"}
