Product Description

From the Manufacturer

The Nikon 7447 Astronomy Serires Astroluxe XL has an 18x high magnification and 720 wide viewfield. This binocular is suitable for astronomy, surveillance, navigation and other professional and specialized applications.

It is equipped with a long eye relief design for wearers of eyeglasses; eye relief, the distance between eyepiece lenses and the eyepoint where the entire field can be viewed without vignetting, is 15.4mm long for a wide viewfield when wearing eyeglasses.

The 7447 has a bright viewfield, large 70mm diameter objectives and multilayer coating applied to all lenses and prisms which increase light transmittance, ensuring a bright field of view.

This binocular is waterproofed for use under such severe conditions as rain, wind and night dew. The nitrogen gas-filled body prevents the binocular from fogging that can otherwise result when binocular is exposed to sudden changes in temperature. The secure viewing rubber ring prevents the dioptre adjustment ring from slipping when exposed to moisture and perspiration.

Product Description

Nikon's astronomy binoculars use durable, all-metal construction and O-ring sealed nitrogen filled tubes for waterproof, shockproof and fogproof performance, and a unique "pebbled" surface to provide ergonomic viewing.Each of the three models utilizes top of the line, coma-corrected lenses and Nikon's exclusive Special Purpose (SP) glass for flare-free pin point image clarity. The glass is specially ground and polished to eliminate surface aberrations and provide crisp, clear resolution and the highest possible light transmission. The lenses and prisms are coated with multiple layers of Nikon's proprietary anti-reflective lens coatings to improve light transmission, enhance color rendition, and provide flare-free viewing. In each binocular, the power is designed to complement a large objective lens delivering the perfect balance of resolution and generous exit pupil.The 10x70 Astroluxe and 18x70 Astroluxe XL are 12" x 9.2" and weigh 69.8 ounces. A 161' field of view at 1,000 yards and a 3.9mm exit pupil give the 18x70 Astroluxe XL a strong blend of light transmission and resolution. All three models are tripod adaptable for steady, detailed observation.
