Astronomy Binoculars

Nikon® 10x50 & 12x50 Action Extreme AE Astronomy Binoculars - 7245 & 7246

Nikon's Action Extreme binoculars are an excellent choice for handheld astronomy binoculars. They feature relatively wide fields of view, excellent coatings, high-index BaK4 prisms, and comfortable eye relief for all users. The 10x50 is traditionally considered the optimal size for handheld astronomical observation. The 12x50 features slightly stronger magnification for teasing out additional detail in the night sky, but is still handholdable for most individuals. The Nikon Action Extreme 10x50 and 12x50 designs feature fields of view of 6.5º and 5.5º, respectively – wider than many competing designs.

The Nikon Action Extreme binoculars feature an all-metal chassis with lens fittings housed in a tough, lightweight polycarbonate body shell. The AE is nitrogen-filled and O-ring sealed for total waterproof, fogproof and shock-resistant performance in virtually any environment. The binocular is ergonomically shaped, tripod adaptable and rubber coated for a non-slip grip, whether wet or dry.

The new Action Extreme offerings utilize high-resolution lenses and prism systems crafted from Nikon's exclusive Eco-Glass, which is made without the use of arsenic or lead. This lens system provides an extremely clear, distortion-free image over the entire field of view. The lens elements each incorporate multi-layered anti-reflective coatings formulated to deliver optimum brightness, high contrast, true color rendition and flare-free viewing in most lighting conditions.

The Action EX series binoculars each feature a unique, click-stop eyecup design that allows eye relief to be customizable to the user's own eyes and/or eyeglasses. The binoculars utilize a center focus mechanism with right diopter control to correct for normal right/left eye vision imbalance.

Every binocular we sell must pass a rigorous 14-point inspection that insures a high degree of both optical and mechanical performance, including testing for accurate collimation. Each model is covered by Nikon's 25-year Limited Warranty, as well as Nikon's exclusive No Fault Repair & Replacement Policy.
