"What I did find was that when I had the Lunt [16x70] and the Helios Apollo out with me, I always wanted to reach for the Lunt: it is simply more pleasurable to use and that pleasure is unquantifiable. it is due to its light weight, its flatter field, and its crisper, more contrasty image. It is a sheer pleasure to use."  Steve Tonkin Binocular Sky Review (pdf)

Lunt Engineering's 11x and 16x Magnesium binoculars feature large 70mm objectives, premium quality fully multicoated optics and Bak-4 prisms in a remarkably light magnesium body.  An excellent choice for astronomy! 

The rigid magnesium body is sealed against the elements. The degree of protection is rated at IPX-7, meaning they can withstand water entry for up to 30 minutes in 1 meter of water so it will easily survive a damp night and if you drop it in the mud you can wash it off under a tap! 

Also, the binocular interior is Nitrogen-purged (the air inside has been replaced with Nitrogen) rendering it 100% fog-proof. The interior will never mist up so the optics remain pristine and free of the spidery fungal growth that affects so many binoculars used in coastal areas. A light rubber armour provides a tactile slip-resistant grip. 

Focus is achieved by adjusting each eyepiece individually and eye-relief is a generous 20mm so eye-glass wearers will have no problem seeing the full image. 

A tripod adapter thread is located on the bridge and covered by a metal cap. To use the binocular on a regular photo tripod simply unscrew the cap then attach the included tripod adapter. 

Includes 5-year manufacturers warranty.
