Designed with large objectives, phase-corrected prisms, and extra-low-dispersion glass, the Hawke Sport Optics 10x50 Endurance ED Binoculars Greenare ideal for low-light situations, such as during predawn and post-dusk periods. The combination of glass and coatings combined with anti-reflection fully multi-coated optics produces bright and clear high-contrast images with accurate color rendition and virtually no fringing. Whether hunting, birding, boating, or watching sporting events, the Endurance ED binoculars will bring your subject up close for making detailed observations.

To help offset the weight of the over-sized objectives, the Endurance ED binoculars are built with a lightweight polycarbonate chassis that is corrosion resistant to help it hold up to a lifetime of outdoor use. It is also temperature resistant, so the optical tubes won't expand and contract with temperature fluctuation, which, over time, can cause the optics to move out of collimation and prevent the binoculars from being able to achieve sharp focus. The chassis is protected by a texturized rubber armor that has an additional pebble texture placed where the palms will naturally fall to give it a non-slip grip especially in cold and wet conditions. The optical tubes are nitrogen filled and O-ring sealed to be waterproof and fogproof - especially in extreme weather conditions. To reduce user fatigue and keep them steady, a tripod adapter mount is located in the front of the hinge for setting them up on a support system. A right-eye diopter adjustment allows the binoculars to be customized to most people's needs, and the twist-up eyecups means they can be comfortably used with or without eyewear.

Q: 1. How do you focus these bad boys? The way I understand it is you focus each ocular at a fixed target. once the left and right ocular are adjusted perfectly to your eyes..thats it..(?). what happens if you want to zero in on a subject 80 yards closer (or further) from your zero'ed in subject.. do you have to recalibrate each ocular again?

A: We can see the Nikon 10x50 WX IF Binocular (Black) does have an individual focusing system for each Ocular, described in the Overview of those binoculars: "To ensure the sharpest views possible, the WX is built with a helical focusing mechanism on each individually focusing eyepiece. Eschewing the conventional center focusing system not only allows precise focusing for any user, but it also ensures the integrity and longevity of its waterproofing. The helical mechanism moves the eyepieces forward and back without rotating the eyepiece lenses, maintaining a centered optical axis that enables even more clarity and sharpness.

Q: 10. Any hands-on reviews of 15x70 ED vs. 20x80 ED, and pros & cons of each? Which is better for astro’ viewing?

A: The Celestron 20x80 SkyMaster Pro ED Binoculars are brighter and have more magnification than the Celestron 15x70 SkyMaster Pro ED Binoculars, and are better for "Astro Viewing"; users will agree. The biggest challenge using the Celestron 20x80 SkyMaster Pro ED Binoculars, is to make sure the tripod that is keeping the image steady is secure.
