One of the easiest ways to project yourself into the vastness of space without ever leaving Earth is to admire the night sky with astronomical binoculars. Comfortably seated in a lounge chair on a clear, dark night and accompanied by your cup of tea or hot chocolate, it would be foolish to miss the evening because of a pair of binoculars not suited to the practice of astronomy . The universe is waiting for you then stop and your binoculars!

In order to benefit from the best experience during your night out to conquer the stars, you must make sure that your binoculars are well designed for astronomy. For this, we offer you the ultimate guide to a successful outing.

Astronomy binoculars or telescope?

Above all, it is worth asking the following question before buying astronomy binoculars. Do you need binoculars dedicated to astronomy or buy a telescope?

The telescopes are big. Even the smallest models are larger, heavier and longer than most astronomical binoculars. Telescopes should therefore be placed on tripods to ensure their stability. 

The inclination of a long tube towards the sky exacerbates the tremor problem. Holding it by your hands makes the objective lens move while binoculars can be locked more easily at eye level. This ensures more stability when searching for constellations or stars.

Telescopes make objects appear larger. This is a problem when observing targets in the deep sky like comets, galaxies and very diffuse star clusters. With the exception of observing the moon and some living planets.

Telescopes only show a small viewing area. Astronomy binoculars, with their wider field of view, allow you to scan the sky in search of stars. They also give you a much better idea of how the objects relate to each other, ideal for observing the constellations.

You will understand that a pair of astronomy binoculars has many advantages compared to a telescope. So what is the best pair of binoculars for astonomy?

How to choose your astronomical binoculars

After considering the reasons why you should choose binoculars rather than a telescope, it is time to think about the important criteria that should not be overlooked when selecting astronomical binoculars. Here are some basic things to consider when choosing a pair of binoculars:

Check binocular specifications

Understanding the technical specifics of binoculars can help you decide which are best suited to your specific needs. We invite you to read our article on the important criteria to take into account when purchasing binoculars.

What magnification and objective?

You may have noticed that there are many different configurations on the market. Some observers prefer a high magnification in order to be able to observe the thousands of luminous points in the sky. It also help to pinpoint with precision the structures composing the galaxies. 

Others opt for immersive observation with a large field to have a more global vision of the sky, thus preferring portability to the power of the objective.

The only real advice I can give you is to buy binoculars that you are most likely to take with you on your travels, whether you go down the street or on the other side of the planet.

This implies a smaller and lighter format, which tends to have a lower magnification. If it is your only pair, I suggest a lens not exceeding 50 mm and a magnification of 10x maximum.

What about smaller astronomical binoculars? This can do the trick as long as they have high quality optical glasses. You can for example opt for 8 × 35 binoculars which also allow bird watching thanks to a wider field of vision than most low power binoculars offer. Thi is generally a plus for observing the sky.

Opt for waterproof astronomical binoculars

We live on the Blue Planet and water can appear in several states. Sometimes it condenses in your binoculars. Sometimes it rains. And sometimes we drop them overboard. Thus, it is wise to use waterproof binoculars to avoid all the inconvenience related to the weather.

Many modern binoculars are coated with rubber to effectively protect against water and shock. But the cheapest binoculars may not be treated against water. Air loaded with water vapor can be sealed in the binoculars and cause rust inside your device. So look for those that have been purged with nitrogen.

Do I need a tripod?

You found the Andromeda Galaxy with your astronomy binoculars. Want to observe it without seeing the stars turn into lightning? Do you also want to show it to your partner? It would then be useful to be able to lock a position in the sky. To do this, you need to make sure that your binoculars have a screw mounting point for attaching a stand such as a tripod.
