Celestron 10X50mm Upclose G2 Porro Prism

This second generation Celestron 10 x 50mm UpClose G2 is a surprisingly affordable high power/wide field 10x magnification binocular that will put you right in the middle of the action. It has big 50mm objective lenses that gather a lot of light for bright and clear images, even in low light. This 10x UpClose G2 will get you up close and personal with sporting events, close to the scenery and wildlife on vacation trips or camping, and close up to anything that's far away and likely to stay there.

The 10x50mm UpClose G2 has a very wide 6.8° field of view (354' at 1000 yards) that's rare in a big 10x binocular. It has fast focusing that lets you keep fast-moving action sharply in view. The 10x UpClose G2 is rubber armored for a comfortable grip and is weather-resistant to shrug off the occasional summer shower (although it is not waterproof). Its 50mm diameter fully coated BK7 optics gather substantial amounts of light, giving it a very high twilight factor of 22.36, well above the twilight factor of 17 recommended for use in the low light of twilight or under overcast skies.

The close focus is 23', making it marginal for use in backyard birding or close-in observing. Usable eye relief is 12mm, so there will be some vignetting for those who must wear eyeglasses while observing. With an aluminum body and a weight of only 27 oz., light for a 50mm binocular, this UpClose G2 is easy to handhold for long periods. Overall, this is a surprisingly affordable high power/wide field binocular for those who want to get very close to the action without spending a fortune.

Features of this binocular . . .

Porro prism optics. Traditional porro prism design using BK7 prisms. Center focus.

Fully coated optics. The optics are treated on all air-to-glass surfaces with antireflection coatings for good light transmission.Critical optical surfaces are multicoated.

Weather resistant. Sealed to resist showers and inclement weather, although not designed to be fully waterproof and fogproof.

Armor. Black rubber armor absorbs noise and shock and provides a good grip when wet. Molded-in ridges for a secure and comfortable grip.

Roll-down eyecups. The rubber-rimmed eyecups roll down for eyeglass or sunglass use.

Close focusing. Focuses to 23', making it marginally suitable for close-in observing.

Fast focusing. About one turn of the large ribbed focus knob moves from the 23' close focus out to the horizon so you can keep track of fast-moving action.

Rotary diopter correction. A variable diopter ring on the right eyepiece allows you to match the binocular optics precisely to your individual eyesight for a sharp image.

Tripod adaptable. For extended no-hands observing, a protective cover on the center hinge unscrews, revealing a 1/4"-10 thread hole for mounting the binocular on an optional photo tripod using an optional tripod adapter. While the 10x50mm UpClose G2 is light enough at 30 ounces to hand-hold, for example at sporting events, the use of a tripod will make for sharper shake-free images during extended observing periods.

Standard accessories. A neck strap, eyepiece and lens covers, and a soft nylon carrying case with shoulder strap are standard equipment.
