Its optical system achieves a sharp 2.9\" resolution, capable of resolving fine detail from its 10m near focus out to infinity. The entire assembly is housed in a durable, IPX4-rated waterproof body weighing 1740g, ensuring it can move from backyard lunar observation to rugged field use for birdwatching without issue.\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 Range: From Wide Fields to 2.9\" Resolution\u003c\/h3\u003e\n\u003cp\u003eThe SV401's primary strength is its seamless zoom capability, moving from a wide 1.75° field of view at 20x to a tightly-framed 0.85° at 60x. This allows you to quickly locate a subject, like the terminator on the Moon, and then increase magnification to study specific craters and rilles.
