Celestron 20X50mm Upclose G2 Porro Prism Binocular

This Celestron 20 x 50mm UpClose G2 is a very inexpensive, very high power porro prism that's light enough to allow comfortable strain-free extended use while watching football and sports, for vacation travel, for family picnics and week-end trips, and more.

This Celestron 20 x 50mm UpClose G2 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 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. And it's light enough to let you use it for extended periods without arm strain.

The 20x50mm UpClose G2 has a 3.2° field of view (168' at 1000 yards) and fast one-turn lock to lock focusing so you can keep fast-moving action sharply in view. 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 42', so it's not suited for backyard birding or close-in observing. Usable eye relief is a short 7mm. 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, light weight, very high power binocular for those who want to get very close to the action without spending a fortune.
