With a focal length of 20 mm and a wide visible field of view of 62°, this eyepiece provides a panoramic view of the starry sky with unsurpassed detail. The patented EMD coating provides maximum contrast and light transmission, making the image bright and clear even when observing faint objects. Argon filling reliably protects the internal optical elements from fogging and moisture, ensuring stable image quality in all weather conditions. Darkened lens edges effectively eliminate unwanted glare and stray light, increasing image contrast. The durable stainless steel housing with carbon elements and a conical safety lock ensures reliable fixation in the focuser and protects the optics from mechanical damage. Folding rubber eyecups allow for quick and convenient eye-level adjustment, and the 15mm eye relief makes observation as comfortable as possible for people with corrective lenses. The sealed design and waterproofing ensure a long service life even in high humidity conditions.\u003c\/p\u003e\u003cp\u003e\u003cmeta charset=\"utf-8\" \/\u003e\u003c\/p\u003e\u003cp\u003e\u003cmeta charset=\"utf-8\" \/\u003e\u003c\/p\u003e\u003cp\u003e \u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003e \u003cb id=\"docs-internal-guid-9291cbd5-7fff-1ba6-c5dd-0627e8466e9c\"\u003e62° visible field of view\u003c\/b\u003e — the wide angular field of view allows you to cover large areas of the starry sky in a single observation, which is especially convenient when searching for objects and observing extended nebulae and star clusters. The wide field also creates the effect of \"immersion\" in outer space and significantly increases the aesthetic pleasure of observations. Compared to standard glasses with a 50° field of view, the view becomes much more panoramic. This is especially valuable when observing the Milky Way and large star fields.\u003c\/li\u003e\u003cli\u003e\u003cp dir=\"ltr\"\u003e \u003cb id=\"docs-internal-guid-9291cbd5-7fff-1ba6-c5dd-0627e8466e9c\"\u003e20mm focal length\u003c\/b\u003e - The medium focus eyepiece provides balanced magnification suitable for a wide range of astronomical objects - from planetary nebulae to large galaxies. At this focal length, the optimal ratio between magnification and image brightness is achieved. The 20mm eyepiece is one of the most versatile in any collection and is often used as the main one for general observations. It works well with both short-focus refractors and mirror-lens systems.\u003c\/p\u003e\u003c\/li\u003e\u003cli\u003e\u003cp dir=\"ltr\"\u003e \u003cb id=\"docs-internal-guid-9291cbd5-7fff-1ba6-c5dd-0627e8466e9c\"\u003eThe patented EMD coating (\u003c\/b\u003e Enhanced Multi-layer Deposition) is a special technology for applying reflective layers to optical surfaces, which maximizes light transmission and image contrast. The coating significantly reduces reflection and scattering of light on each lens surface, which is especially important when observing dim objects in deep space. Thanks to EMD, color reproduction remains natural and saturated without unwanted color aberrations. This coating is a proprietary development of Explore Scientific and favorably distinguishes the brand's glasses from most competitors.\u003c\/p\u003e\u003c\/li\u003e\u003cli\u003e\u003cp dir=\"ltr\"\u003e \u003cb id=\"docs-internal-guid-9291cbd5-7fff-1ba6-c5dd-0627e8466e9c\"\u003e15 mm eye relief (\u003c\/b\u003e LER) is the distance from the last eyepiece lens to the point where the observer's pupil is placed to obtain a full field of view. A value of 15 mm is comfortable for people who wear glasses, since the frame glass does not interfere with obtaining a full field of view.","brand":"Explore Scientific","offers":[{"title":"Default Title","offer_id":47654066684081,"sku":"932382_sv","price":8748.83,"currency_code":"UAH","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0538\/8517\/3937\/files\/1782743885337_vmx0e2_12049033546174__65ae119548.jpg?v=1782743893","url":"https:\/\/usefulrare.com\/products\/explore-scientific-62-ler-ar-20mm-125-eyepiece-11605","provider":"Dostavka","version":"1.0","type":"link"}
