Nikon ASTROLUXE XL Overview

  • 1Description

Engineered for wide-field astronomy such as enjoying stunning views of the moon, picking out your favorite constellations, comet hunting, satellite spotting, or watching for iridium flares, the Nikon 18x70 Astroluxe Binocular is an ideal companion for dark and starry nights.

The Astroluxe is outfitted with relatively low magnification to ensure a generous field of view for easier viewing—especially when holding it by hand. The traditional Porro prism light path presents a rich depth of field, while producing a naturally balanced and comfortable feel in the hand. To enhance the view, Nikon utilizes winged eyecups that conform to your face, keep stray ambient peripheral light from interfering with the view and causing distractions, and increase contrast and clarity.

The chassis' ergonomic feel is complemented with textured armor to further improve grip security. Both optical tubes are nitrogen filled to be waterproof and resistant to the internal fogging that can occur when moving from the inside of a warm house to the outside into cold winter or sultry humid summer nights. Weighing in at 4.5 pounds, holding the Astroluxe can cause some users to experience arm fatigue—especially during long observation sessions—so Nikon made it mountable on a wide variety of photo, video, or field tripods with the simple addition of an optional adapter for hands-free use to ensure vibration-free views and easier tracking of fast-moving subjects.

Optical Performance
  • High 18x power allows users to enjoy a magnified view without sacrificing field of view
  • Large 70mm objectives draw in the amount of light required to keep views bright and clear when using during nighttime astronomical observations
  • Traditional Porro prism design produces a comfortable-to-hold and natural hand placement for a balanced grip and presents a rich depth of field when viewing terrestrial objects
  • Fully multicoated optics, engineered specifically for nighttime use, maximize light transmission for improved color rendition, contrast, and clarity
  • Wide 64.3° apparent angle of view makes the binocular ideal for viewing the moon, constellations, satellites, and the International Space Station, and for comet/asteroid hunting
  • 210-foot field of view at 1000 yards
Use and Handling
  • Individually focusing eyepieces ensure tack-sharp views, regardless of individual optical prescription
  • 56-72mm interpupillary distance adjustment range
  • Fold-down winged rubber eyecups mold themselves to the user's eye socket to eliminate distracting peripheral light for improved contrast and clarity
  • Tripod mountable with optional adapter for hands-free use eliminates vibrations and hand shake and prevents arm fatigue from holding it
  • 15.2mm eye relief improves viewing comfort with reduced eyestrain, especially during long observation sessions
  • 3.9mm exit pupil will cover pupils they open and dilate in the dark
