Celestron 8×21 Compact Pocket Binocular Roof Prisms

Celestron 8×21 Binoculars

Pack these all-purpose ultra-compact binoculars along for sporting events, vacations, hikes, or outdoor adventures to observe birds and wildlife.

Coatings and Prisms

Inside the UpClose G2 are two roof prisms, each paired with an auxiliary prism. Roof prisms create a straight line between the eyepiece and objective lens, making the binocular more compact—perfect for stashing in a jacket pocket or purse. Our roof prisms are constructed of BK-7 optical glass, which provides high reflectivity so that more light passes through the optical path to your eye.

UpClose G2 also contains other optical surfaces treated with special coatings to boost light transmission even more. The result is a brighter view than uncoated binoculars.

The Body

Whether you are out on the trail or inside a crowded stadium, you want a binocular that is comfortable to hold and use over long periods, without fear of bumps or drops. UpClose G2 features a lightweight and durable armor-protected chassis. Its tough, rigid frame is coated with rubber to stand up to hard use in the field. The UpClose G2 is also water resistant and can repeatedly stand up to unexpected conditions.

Viewing through UpClose G2 is comfortable for eyeglass wearers and non-eyeglass wearers alike, thanks to its rubber eyecups. Keep the eyecups up for proper positioning of the eyes without glasses. If you are wearing glasses, simply fold them down and out of the way.

Perfect for a Variety of Uses

UpClose G2 features 8x magnification, the perfect boost in power for sporting events, sightseeing, birding, wildlife or whale watching, and more! You will get great views of distant subjects, plus a wide field of view so you can easily follow them as they move. But this 8×21 binocular also offers a close focus of just 10 feet so you can also get detailed views of subjects in closer range. No matter how you choose to observe, this versatile binocular is a solid all-around performer.

Accessories Included

UpClose G2 includes a built-in neck strap for easy carrying. The binocular also includes a protective soft case for storage and transport so you can take it anywhere with confidence.
