They feature premium optics, advanced coatings, high-quality internal components, and durable housing materials for enhanced performance. Equipped with large objective lenses, BaK-4 prisms, ED glass, and fully multi-coated optics using Celestron’s proprietary XLT coating technology, SkyMaster Pro ED delivers bright, sharp, high-contrast images. Its advanced optical design sets a high standard for astronomy binoculars and long-distance observation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eED Objective Lenses\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eExtra-Low Dispersion (ED) glass virtually eliminates chromatic aberration, also known as color fringing, a visual phenomenon common in magnified optical systems.

What’s more, the prisms inside the binocular are made of high-quality BaK-4 glass, further boosting light transmission. Working together, the fully multi-coated lenses and BaK-4 prisms deliver more light from your target to your eye for brighter, more detailed views.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eObjective Lenses\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 80mm objective lenses offer plenty of light-gathering ability for superior low-light performance. The objective diameter-to-magnification ratio is ideal for scanning the skies, observing the Moon and planets, and exploring all the best deep-sky objects. Celestron SkyMaster Pro ED also makes an excellent choice for long-distance land-based viewing—especially at dawn or dusk.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Body\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cspan dir=\"ltr\" class=\"ui-provider ceb cec c d e f g h i j k l m n o p q r s t ced cee w x y z ab ac ae af ag ah ai aj ak\"\u003eCustom-designed rubber armor and a durable chassis protect your SkyMaster Pro ED binocular from damage without weighing you down. Viewing through SkyMaster Pro ED binoculars is comfortable for eyeglass and non-eyeglass wearers alike, thanks to the retractable eyecups and more than 15mm of eye relief. Eyeglass wearers can see the entire field of view while looking through the eyepiece with their glasses by twisting the eyecups down. For those who do not wear eyeglasses, the eyecups position the user’s eye behind the eyepieces at the correct distance for optimal viewing.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWays to Observe\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cspan class=\"ui-provider ceb cec c d e f g h i j k l m n o p q r s t ced cee w x y z ab ac ae af ag ah ai aj ak\" dir=\"ltr\"\u003eThe Celestron SkyMaster Pro ED binocular is tripod-adaptable.

Adding the right filter can deliver game-changing views for terrestrial and celestial observing. For terrestrial observation, filters can reduce the brightness of sand, snow, and water. For nighttime viewing, filters can cut glare, minimize eye strain, increase contrast, and even combat the effects of light pollution. Remember, the binocular needs a set of two filters.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe width=\"500\" height=\"300\" src=\"https:\/\/www.youtube.com\/embed\/yRK5yyOhh4k\" title=\"SkyMaster Pro ED Product Tour\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eCelestron’s legendary SkyMaster binoculars get an upgrade with ED objective lenses for superior images virtually free of chromatic aberration with lifelike color, increased resolution, and improved contrast\u003c\/li\u003e\n\u003cli\u003eLarge, 80mm objective lenses offer excellent light-gathering ability—perfect for astronomy\u003c\/li\u003e\n\u003cli\u003eThreaded eyepieces accept all standard 1.25” astronomical eyepiece filters to bring out details or reduce the effects of light pollution\u003c\/li\u003e\n\u003cli\u003eBaK-4 prisms and fully multi-coated optics with XLT coatings boost light transmission through the optical path for brighter, more detailed images\u003c\/li\u003e\n\u003cli\u003eThe widely spaced objective lenses of the Porro prism optical design provide an enhanced 3-D view\u003c\/li\u003e\n\u003cli\u003eEyeglass-friendly with generous eye relief and padded twist-up eyecups\u003c\/li\u003e\n\u003cli\u003eDurable rubber-armored housing with improved ergonomics for comfortable use in the field\u003c\/li\u003e\n\u003cli\u003eTripod-adaptable for extended viewing sessions\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Celestron","offers":[{"title":"Default Title","offer_id":48168228192427,"sku":"72035","price":449.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0799\/8944\/0683\/files\/72035_SkyMaster_Pro_ED_20x80mm_Porro_Binocular_01.webp?v=1791392832","url":"https:\/\/astronomycity.com\/products\/celestron-skymaster-pro-ed-20x80-porro-binoculars","provider":"Astronomy City","version":"1.0","type":"link"}
