If you're interested in investing in a pair of binoculars for observing both starry vistas and terrestrial subjects, then you might want to take a look at the Orion Giant View 15x70 Astronomy Binoculars. These porro-prism beauties are well designed, rugged and very versatile. What's more, they've been engineered to give lasting performance.
Weighing in at a hefty four pounds, the Orion Giant View 15x70's have been reinforced with an aluminum rod and the objective cell frame has also been beefed up for maximum structural rigidity. While this adds weight, it also ensures that no matter how many times these binoculars are flexed open to accommodate being stored, or adjusting to individual eye separation distances, they are going to remain in alignment. No one wants to pay good money for a pair of binoculars that feel like they are going to come apart where the barrels are hinged together! There is also a captive sliding 1/4"-20 mounting post located on the rod - a big bonus when considering mounting the binos to a tripod.
The next thing you'll notice about the Orion Giant View 15x70 Astronomy Binoculars is that each eyepiece is individual focus - a change over the traditional right eye diopter. This facet of the Giant View 15X70's construction means you get a more improved focusing precision over center-focus mechanisms, however you may wish to secure the binoculars to a mount and tripod arrangement to take advantage of this unique feature.
Another high quality addition is the BAK 4 prisms and internal baffling. This provides for excellent image contrast and sharpness. You'll also find the full multi-coatings to be exceptional - reducing glare and offering excellent color correction. The 4.6mm exit pupil is right on par with the average adult maximum exit pupil, and 18mm of eye relief means you're not dangling the binoculars out in space to see through them, nor do you have them crammed against your eyes.
As for the view? At 15X and 70mm of aperture, you're enjoying a vision comparable to a small refractor telescope. However, instead of a constricted field of view, you're checking out a full sixty degree apparent field of view and a very nice four degree angular field. For astronomical purposes, that means being able to follow an extensive comet tail, or being able to take in expansive nebulae regions and admire large star clusters. The Orion Giant View Astronomy binoculars are quite capable of picking up brighter galaxies, too! Put these binoculars on a tripod and you'll be able to resolve out wider double stars and take on some serious crater action when it comes to the Moon. Don't forget the planets! Not only are they are capable of revealing the four Galiean moons of Jupiter, but you'll also be able to spot the shape of Saturn's ring system, reveal the orb of Mars, catch the bright form of Venus, pick Mercury out of the dawn or dusk and capture the distant twinkle of Uranus.
Hang on, because the Orion Giant View 15X70 binoculars are good for more. Pass them on to a hunter and they'll be delighted with the close-up view of distant game. You'll be able to see the foraging deer and spot antlers. With the 70mm aperture, you'll enjoy exceptional low light resolution. This is especially helpful at dawn and dusk when they are on the move. Maybe birds are more your thing. If so, set a pair of these big binos on a tripod and train them on a feeder. You'll feel like you're feeding with the flock! There's more. The Orion 15X70 Giant View binoculars also come with a deluxe hard case. You'll appreciate its added security. Now you can safely keep your binoculars with you in your car's trunk, take them along as carry-on luggage on an astronomy expedition, or add them right to your gear for hunting, hiking and camping trips.
