| This Celestron 20 x 50mm UpClose is a surprisingly affordable very high power 20x magnification binocular that will put you right in the middle of the action. It has good-sized 50mm objective lenses that gather a lot of light for bright and clear images. This 20x UpClose 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 20x50mm UpClose has a 3.2° field of view (168’ at 1000 yards) and very fast focusing so you can keep fast-moving action sharply in focus. It’s rubber armored for a comfortable grip and 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 31.62, making it a very useful performer in the low light of twilight or under overcast skies. The close focus is a not very close 36’, so it’s not suited for backyard birding or close-in observing. Usable eye relief is a very shot 2.5mm. There will be considerable vignetting for those who must wear eyeglasses while observing, so these are not recommended for eyeglass wearers. Overall, this is a surprisingly affordable very high power 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.
Weather resistant. O-ring 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-up eyecups. The rubber-rimmed eyecups roll down for eyeglass or sunglass use.
Close focusing. Focuses to 36’, making it unsuitable for close-in observing. This binocular is designed for long distance viewing exclusively.
Very fast focusing. Less than a third of a turn of the large ribbed focus knob moves from the 36’ 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"-20 thread hole for mounting the binocular on an optional photo tripod using an optional tripod adapter. While the 20x50mm UpClose is light enough 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 neckstrap, eyepiece and lens covers, and a soft nylon carrying case with shoulder strap are standard equipment.
Lifetime warranty. This Celestron UpClose has a lifetime no-fault warranty. If it breaks or becomes unusable, no matter how it happens or whose fault it is, Celestron will repair or replace the binocular for just a $25 shipping and handling charge.
