This optical system achieves a sharp 2.0\" resolution, while the IPX5 waterproof and nitrogen-purged body ensures reliable function in any weather. With a generous 20mm-18mm of eye relief and a dual-speed focuser that snaps subjects into clarity from just 5.5m away, the SV406P is built for critical observation.\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\u003e80mm ED Glass: True-Color Views with 2.0\" Resolution\u003c\/h3\u003e\n\u003cp\u003eThe core of the SV406P is its 80mm objective lens, crafted from ED glass. This material corrects for chromatic aberration, eliminating the purple and yellow fringing that can soften images in standard scopes, especially on high-contrast subjects like a bird against a bright sky. The result is a view with true-to-life color and sharp detail, capable of resolving down to 2.0 arcseconds.\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\u003e20-60x Zoom Eyepiece: A 66° Field in a 1.25\" Barrel\u003c\/h3\u003e\n\u003cp\u003eThe included zoom eyepiece provides a magnification range from 20x to 60x, allowing you to scan a wide 108-foot field of view at 1000 yards and then punch in for detailed study. As you increase magnification, the apparent field of view expands from 42° to an immersive 66°. Because the scope uses a standard 1.25-inch eyepiece barrel, you have the option to swap in specialized fixed-focal-length astronomy eyepieces for different perspectives.\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\u003eDual-Speed Focuser: Precision Control from 5.5m to Infinity\u003c\/h3\u003e\n\u003cp\u003eAchieving critical focus, especially at 60x magnification, is managed by the dual-speed focusing mechanism.

Its IPX5 waterproof rating means it can withstand direct jets of water, so you can keep observing through rain or sea spray without concern.
