APM 16 x 70 Magnesium ED APO Binocular with Nitrogen Filling

A good pair of 16 x 70 binoculars can be an amateur astronomer´s best friend. Step outside on your porch and scan the skies for the latest comet, or grab a lawn chair and peruse the Milky Way to discover wispy galaxies and clusters of stars that shine like jeweled boxes in the night. However, don´t put your APM MS 16 x 70 Magnesium ED APO binoculars away once the Sun comes out! These big binoculars, with their over-sized 70 mm optics, are a joy to use for nature observations. Unlike many telescopes, the APM MS 16 x 70 Magnesium ED APO´s are portable and easy to take along on a trip, with or without a tripod. Let´s look at the many features you´ll enjoy if you pick up a pair of APM MS 16 x 70 Magnesium ED APO Binoculars:

Amazing Optics: The heart of a pair of binoculars is the optics. It doesn´t matter how beautiful they are, or how much they cost if the optics don´t give you a clear, sharp, true color image of the world around you. APM Magnesium ED APO binoculars, regardless of their magnification or aperture, use quality ED (FK61) glass and BAK-4 prisms to yield high contrast, tack-sharp images over their entire field of view. Special coatings on all optical surfaces enhance the final result producing true-to-life color.

IPX-7 Water Protection: The International Electrotechnical Commision, or IEC, classifies and rates the degree of protection provided against the intrusion of water into a system that would suffer from damage were that to happen. The APM Binoculars have an IPX-7 rating, which means they are capable of withstanding water entry for up to 30 minutes in 1 meter of water. We realize this sort of mishap will most likely not happen, but this superior protection will keep your binoculars safe if they get rained on or splashed.

Rugged, Lightweight Body: The APM binoculars have a body made from Magnesium, the lightest of the metal elements. Magnesium is also noted for its strength and resistance against corrosion. The binocular body is over-coated with a rubber armor, which further protects the binoculars and offers a slip-resistant grip without adding much weight. Focus is achieved by adjusting each eyepiece individually so that you can match your unique vision precisely. A tripod adapter port is located on the bridge and is covered by a metal beauty cap. To access the port, simply unscrew the cap and attach the included tripod adapter.

Good Eye Relief: The APM 16 x 70 Magnesium ED APO Series Binoculars have very comfortable eye relief of 20 mm. The term "eye relief" has to do with where your eye has to be placed to see the full image being produced. The lower the eye relief, the closer your eyes will need to be when positioned against the eyepiece. If you happen to wear eyeglasses and wish to observe with them on, eye relief becomes very important. Since APM Magnesium Binoculars have great eye relief, all you have to do if you want to wear glasses is to fold down the rubber eyecups. For non-eyeglasses wearers, keep the eyecups unfolded.

Nice Accessories: All APM ED APO Magnesium Binoculars come with a tripod adapter, a Cordura-Type soft carry case, a binocular strap, lens caps and eyepiece caps.
