The National Geographic Excursion Series 10x42 delivers 10x magnification with BAK-4 prisms and fully multi-coated optics in a waterproof, fog-proof body — more reach than the 8x42 for picking out detail on distant wildlife, ridgelines, and deep-sky star fields.

Features

• 10x magnification with BAK-4 roof prisms — pulls distant subjects closer with bright, high-contrast images and accurate color
• Fully multi-coated lenses — maximum light transmission for clear views from dawn through dusk
• Waterproof and nitrogen fog-proof — sealed optics perform reliably in rain, humidity, and rapid temperature changes
• 2-meter close focus — sharp detail on nearby birds and wildlife without backing away
• 15mm eye relief with twist-up eyecups — comfortable viewing for eyeglass wearers
• Open bridge roof prism design — secure grip and balanced handling for extended glassing sessions
• Diopter adjustment — fine-tune focus independently for each eye
• Includes lens covers, neck strap, and storage case — field-ready out of the box

Ideal For

• Wildlife and bird watchers who need the extra reach of 10x to identify species at distance — shorebirds, raptors, and skittish game
• Hikers and nature travelers — waterproof construction and lightweight design handle any trail conditions
• Stargazers — 10x42 is a popular format for scanning the Milky Way, open star clusters, and large nebulae
• Eyeglass wearers — 15mm eye relief and twist-up eyecups provide a comfortable, full field of view
