Quite often amateur astronomers who have a good pair of 7x50 or 10x50 binoculars want to upgrade to a larger pair of binoculars. The 80 or 100mm aperture sized binoculars can be quite heavy and require a good sturdy tripod as they are too heavy to hold. So a good compromise are binoculars with 70mm aperture objectives and 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 ED APO 16 x 70 Magnesium 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 16 x 70´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 ED APO 16 x 70 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 binoculars, regardless of their magnification or aperture, use quality ED glass (FK61) 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 ED APO 16 x 70 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 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 ED APO 16 x 70 Magnesium 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 telescopes 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 Binoculars come with a tripod adapter, a Cordura-Type soft carry case, a binocular strap, lens caps and eyepiece caps.
