Celestron Upclose G2 7-21x40 Zoom Binoculars Details

With a simple flick of the lever located near the right eyepiece, these Celestron Upclose binoculars enable you to adjust the zoom from a moderate 7x, right up to a very powerful 21x power.
At the lower magnification settings, you are presented with a wide field of view making it easier to locate and follow objects. Then should you require greater image detail, you can increase the magnification to a level that you desire. You will need a steady hand at the high power setting to keep the image still, or should you wish, this binocular is tripod adaptable and thus makes it very straightforward to fix onto a tripod.
The 40mm objective lenses are large enough to be able to capture a reasonable amount of light and thus at the low magnification settings they will perform reasonably well in low light. But at the same time, they are small enough to keep the overall size of the instrument down to a level that makes these binoculars easy enough to pack away and carry about.
Because of the wide range zoom, these binoculars are very versatile and can effectively be used in a number of areas including most outdoor activities like wildlife observation, bird watching, hunting, boating, sporting events, and astronomy.

About Celestron UpClose Binoculars

Extremely affordable Celestron UpClose series offers binoculars for a different use, among which are also two zoom models with adjustable magnifications for finest details without the need to move to another location. You can choose between the smallest binoculars on the market with 8x21 configuration and large 20x50 configuration for nighttime observations. You can take them with you on sports events, concerts, when hiking, huntingbirdwatching or looking at the night sky for stars, comets, planets etc. The smallest model has a roof prism design and larger has a Porro prism design that helps to enhance light transmission. UpClose binoculars are multi-coated, using BK7 glass and splash-proof that protects them in damp areas and are equipped with central focusing mechanism instead of the individual. 

Basic Features

UpClose binoculars are made out of extremely durable aluminum housing that helps to protect them against impacts together with rubber armoring. Small dimensions that make them compact also help with easier portability and comfortable handling, even when using them for longer periods of time. UpClose binoculars are splash-proof, which means they aren’t waterproof and fog-proof but are still durable and tight enough to prevent damage when used in the damp areas. Fully sized models are also tripod adaptable which allows you to mount them on a tripod and get steadier images.

Optical Properties

UpClose series offers binoculars for different kinds of use. Depending on the power and objective lens diameter, you can choose between fixed or zoom configuration. The zoom binoculars allow you to make power adjustments – changing magnification without the need to change the position. The Porro prism system of bigger fully sized models draws in more light and allows you to gather enough brightness even in the low-light conditions which are extremely convenient for astronomy observations. BK7 prisms and multi-coated system also help to enhance brightness, contrast, and colors without major distortions and reflections. They are equipped with central focusing mechanism and left-eye diopter to make proper adjustments. Foldable eyecups have a 12mm eye-relief so it’s suggested to try them on if you are eyeglass wearer. 

Accessories

UpClose binoculars come in a case for storage and protection with a binocular strap. They are also equipped with objective lens covers and eyecups covers to protect the lenses, however, they’re only included in bigger models, not in smaller roof prism models.
