Open Bridge Binoculars

VIDEO

Introduction

Is the built design of binoculars merely a matter of liking, or are there genuine advantages to this type of device? When picking the right pair of binoculars, considering the type of bridge might be worth it. The type of bridge is of utmost importance when it comes to holding the binoculars regarding the comfort, weight, or it could merely help you when choosing the more aesthetically appealing pair of optics.

The open-bridge design is a newer design, mostly in the last two decades. First, the manufacturers producing this type of optics only produced the more expensive models that way, such as Swarovski's EL model. Now, as time has moved forward, the very affordable binoculars from entry-level classes can also feature the open bridge.

However, not all pairs of binoculars are built this way, as the open-bridge ones are mostly used with roof prism binoculars. These binoculars feature a two joint construction and are always used with central focusing. The barrels provide an open space in the middle, between the barrels, which makes the space wide enough for the user's hand. This is one of the advantages, but let us take a look at more:

Pros

An advantage of binoculars having an open bridge design is, firstly, a better grip, so they feel more secure – which is the most obvious one. Simultaneously, a better grip means a construction that is sturdier, as well as easier to use with one hand. Another advantage would be, in some cases, smaller weight. Consequently, open-bridge binoculars are easier to use with smaller hands, and there is an added bonus: the design is nicer and the binoculars (for most) look more aesthetically pleasing than single bridge binoculars.

Cons

With that many advantages, there are also some disadvantages, but not as plenty, except if the price of the binoculars is your main concern, as these optics can be on the pricier side. The binoculars are built in a way that they are longer, which may pose a problem for some, and the focusing knob position on some models is positioned too towards the face, which makes it difficult to reach.

Conclusion

If you are seeking to figure out if the positive advertised open-bridge binoculars are an instance of a publicity stunt in the optics world, or if the design truly has its benefits, we can confidently confirm it is the latter. True, in some instances, these binoculars are more expensive, like in the case of all the best premium binoculars from the higher classes, like Swarovski EL, Zeiss Victory SF, and Leica Noctivid. However, in this case, getting a great deal should not be your priority – open-bridge binoculars are worth paying extra for.

Astronomy binoculars are often said to be the best first telescopes to slowly introduce you to sky gazing and astronomy. With wider field of view than telescopes they allow you to scan the whole sky at once and easily track the observing object. They are more portable, lighter, less bulky and do not require a tripod because lower magnifications bring less shaky images and easier handling. The main advantage of astronomy binoculars is that you are allowed to see with both of the eyes, giving you more natural viewing and easier tracking of the objects - two barrels collect more light. An important factor in astronomy binoculars is the size of the objective lens as they are mostly used in low light situations (at twilight or in pitch dark). The bigger the lens, more light is let through. Increase in light, high quality optics and coatings all contribute to brighter and more detailed image. Astro binoculars may be only water resistant which is enough of a feature to protect your binoculars before dew and moisture occurring at night. Waterproof and fog-proof features just add to the price. Astronomy binoculars may not be a replacement to a telescope, they are simply an addition.

Features of Astro binoculars

(+) bigger lens diameters
(+) wide field of view
(+) portable
(+) suitable for low light observations
(-) heavier in comparison to other binoculars

A few reasons why the astronomy binoculars are (sometimes) better than the telescope

Astronomy binoculars are suitable for anyone who does not want a large and clumsy telescope. For the telescope, you will spend a lot more time if you want to set it up for the observation. Astronomy binoculars are smaller and have smaller magnification, but for this reason, they are extremely compact and portable. They also have a much larger field of view than the telescope and because of the use of both eyes, observation is much more natural and comfortable. They capture a larger amount of light and, consequently, the image we see is much brighter. It is important that we choose a magnification below 12x if we want to hold the binoculars in our hands and observe; otherwise, they will need to be mounted on a tripod. With astronomy binoculars, you can see a larger number of stars and clearer planets, however, for the details and even more focused observation, choose a telescope.
