Celestron UpClose G2 8x40mm Porro Binoculars

Get up close to the action with UpClose G2 binoculars. Pack these binoculars along for sporting events, vacations, hikes, or outdoor adventures to observe birds and wildlife. The UpClose G2 8×40 will be your binocular of choice.

Coatings and Prisms

Inside the UpClose G2 are two Porro prisms, reflective optical prisms that the form of a right-angle triangle with two sides of equal length. Porro prisms make binoculars more compact without compromising focal length or the dispersion of the light rays as they pass through it giving the classic “broad-shoulder” shape of a traditional binocular.  Our Porro prisms are constructed of BK-7 optical glass, which provide 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 an ultra-wide field of view so you can easily follow them as they move. The 40mm aperture brings in more light for more detailed views, especially when viewing conditions are dim. No matter how you choose to observe, this binocular is a solid performer.

Ways to Observe

UpClose G2 is tripod-adaptable, so you can mount it on any standard photographic tripod for extended viewing or digiscoping (photography through the eyepiece). The tripod adapter is sold separately.  With the detachable objective lens caps, you’ll be able to keep your lenses protected at all times. Plus, the large, smooth focus wheel is easy to turn allowing you to focus on subjects at varying distances even with gloves on.

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.
