Explore both starry skies and daytime vistas, rain or shine! Orion 10x50 E-Series Waterproof Astronomy Binoculars will give you great views without having to worry about rain or damp weather conditions. Enjoy amazing views of comets, star clusters, the Moon and more - weather or not.

At 10-power, this binocular is more powerful than typical 7x50 or 8x42 binoculars, which means you'll be able to tease out better views of night sky treasures such as smaller star clusters and craters on the Moon's rugged surface. The binoculars' big, 50mm objective lenses collect over 50 times the amount of light that your eye can grab, so you'll be able to see many, many more celestial objects in much greater detail than with unaided eyes.

Multi-coated optics and top-quality BAK-4 porro prisms deliver a bright, 6.5° field-of-view to the eyepieces. Its long, comfortable 19mm eye relief makes the 10x50 E-Series a relaxing binocular to use, even if you wear corrective lenses while observing. You won't have to worry about unexpected rain or foggy weather with Orion 10x50 E-Series binoculars thanks to their waterproof construction.

It's often said that the best first optical instrument for a beginning astronomer is a good pair of 50mm binoculars. The vast, expansive field-of-view provided by a pair of binoculars lets you observe a larger chunk of sky compared to the narrower and, in general, more powerful view provided by most telescopes. By displaying a wider section of sky at moderate power, binoculars provide beginning astronomers with a rewarding, big-picture view of the cosmos. This Orion 10x50 E-Series binocular is an excellent choice for those just starting to explore the wonders of the night sky, and would also be a welcome addition to a more experienced hobbyists' collection of astronomy equipment. Using these 10x50 E-Series Waterproof Astronomy Binoculars alongside your favorite telescope will enhance your night sky explorations as you alternate between the wider binocular view and more powerful but narrow telescopic view.

These astronomy binoculars weigh 2.15 lbs. and can be hand-held comfortably for stargazing or daytime use, and they feature a threaded tripod adapter port for those times when you want to attach the binoculars to a tripod for added stability. The Orion 10x50 E-Series Waterproof Astronomy Binoculars are 6.75" tall when placed on a table, and they include a soft carry case and lens caps.
