Extra-Low Dispersion (ED) glass, proprietary XLT coatings, and BaK-4 prisms work in concert with the 50mm objective lenses to produce razor-sharp, high-contrast images free of chromatic aberration. With a massive 7.8° field of view and a bright 6.4mm exit pupil, this binocular is purpose-built for scanning the Milky Way, observing large nebulae, and long-distance terrestrial viewing in low-light conditions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eED Glass and XLT Coatings: A 7x50 System Free of Color Fringing\u003c\/h3\u003e\n\u003cp\u003eAt the heart of the SkyMaster Pro ED are its objective lenses, crafted from Extra-Low Dispersion (ED) glass to virtually eliminate chromatic aberration. This prevents the distracting color fringing (purple and yellow halos) common in standard binoculars when viewing high-contrast targets like the Moon's limb, Jupiter, or bright stars. Paired with Celestron’s proprietary XLT lens coatings and high-quality BaK-4 prisms, light transmission is maximized for exceptionally bright and detailed views, especially at dawn and dusk.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e7.8° Field of View: Scanning the Milky Way at 7x Magnification\u003c\/h3\u003e\n\u003cp\u003eThe 7x magnification and 50mm aperture are perfectly balanced to produce an extremely wide 7.8° true field of view, spanning 409 feet at 1000 yards. This expansive perspective allows you to frame entire constellations, sweep through the dense star fields of Sagittarius, or track moving subjects on the ground without constantly repositioning. The resulting 6.4mm exit pupil delivers a bright, fully illuminated image to your eye, critical for detecting faint details in deep-sky objects.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eBuilt for the Field: 20.8mm Eye Relief and IPX7 Waterproofing\u003c\/h3\u003e\n\u003cp\u003eDesigned for real-world use, the SkyMaster Pro ED features a durable chassis protected by custom-designed rubber armor. The body is fully nitrogen-purged and sealed to an IPX7 waterproof standard, preventing internal fogging in damp conditions. A standout feature is the extremely long 20.8mm of eye relief, which allows eyeglass wearers to see the entire field of view comfortably without removing their glasses. At 44.3 oz (1,255g), these binoculars have significant heft, making them ideal for tripod mounting for stable, extended observing sessions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eAstronomical Versatility: Threaded for 1.25\" Eyepiece Filters\u003c\/h3\u003e\n\u003cp\u003eUnlike nearly any other binocular on the market, the SkyMaster Pro ED's eyepieces are threaded to accept standard 1.25” astronomical filters. This transformative feature allows you to enhance your views just like you would with a telescope. Thread in a pair of UHC or O-III filters (sold separately) to dramatically increase the contrast of emission nebulae like the Orion Nebula (M42) or the North American Nebula (NGC 7000), revealing details that would otherwise be invisible against a light-polluted sky.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eSkyMaster Pro ED vs. Standard Binoculars: The Value of ED Glass\u003c\/h3\u003e\n\u003cp\u003eWhile many binoculars offer similar magnification and aperture, the use of ED glass sets the SkyMaster Pro ED apart. When observing a bright planet or a crisp lunar crater edge through a standard binocular, you will notice a soft halo of color that degrades sharpness and contrast. The SkyMaster Pro ED corrects for this at a glass level, delivering a true-to-life, high-fidelity image where stars are rendered as sharp points of light and planetary details are clearly defined.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the main advantage of the SkyMaster Pro ED 7x50's ED glass?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe \u003cstrong\u003eExtra-Low Dispersion (ED) glass\u003c\/strong\u003e virtually eliminates chromatic aberration, or color fringing.
