About Orion 10x50 Porro Prism

The Orion Resolux 10 x 50 Waterproof Astronomy Binoculars are equally superb for long-distance daytime viewing, combining high-resolution, flat-field optics with mechanical construction that meets the U.S. military spec for ruggedness and the strict JTII spec for collimation. They are fully waterproof and nitrogen purged to prevent internal lens fogging. With this Resolux 10 x 50 binocular, you'll enjoy performance that you simply won't find in other binoculars. Your first scan of the Milky Way will prove it pinpoint stars set in bold contrast against the dark background.

The extra-large BAK-4 prisms and advanced multi-coatings on all optical surfaces really drink in the light. The eyepieces focus individually, which yields a sturdier mechanical design than a center-focus mechanism. And with 18mm of eye relief, even eyeglass wearers will see the full field of view. This Resolux's all-metal housing is armored with thick rubber to ensure a secure, comfortable grip. Each binocular comes with lens caps, heavy-duty tripod adapter, soft padded case and neck strap.

What You Can See


from Crestview, Fl  -  Casual/ Recreational

You can see great views of the moon, Saturn, the moons of Jupiter, and many star clusters in the sky. They are also great for bird watching and sporting events. This kit is perfect for someone who is just getting interested in viewing the night sky. Attaching these binoculars to a tripod will provide great stable views while the included planisphere will help identify objects in the sky. An inexpensive option to buying a telescope. A great buy!
