Which Magnification is better for Astronomy Binoculars?

With a good binoculars 10×50, the starry sky can be well observed. The 10x magnification is enough to get a good overview of the starry sky and to locate constellations. The 50 mm lens diameter allows enough light to have an optimal image even at night. A pair of binoculars with the values 10×50 is great for astronomy.

Who would like to enjoy deeper glances in the starry sky, should set to a larger magnification. Here, for example, 15x, 20x or even 25x fold magnification, with an objective diameter of up to 50mm or 80 mm are considered to be ideal binoculars for astronomy.

The disadvantage of these models, however, is the greater weight and a tripod is usually no longer around at such magnifications. Good tripods, however, are already available for around $20.

Alternatively, opt for a pair of binoculars with image stabilizer. For astronomy binoculars you should follow:

  • At least a 10x magnification.
  • At least one objective diameter of 50 mm.
  • For models with 15-30x magnification or more, a tripod should be used.

Can you see planets with astronomy binoculars?

First of all, we need to state that with binoculars for astronomy, you can observe detailed details on planets, such as with a good telescope.

However, you can observe stars, even entire star clusters, as well as fog or even galaxies, are easy to spot. For such a sight, a purchase undoubtedly worthwhile!

By and large, the great binoculars for astronomy will make it so much easier for you to view most of the planets in our solar system such as Venus, Jupiter, Mercury, Mars and the rest.

Astronomy Binoculars vs Telescope

The biggest benefit of the Astro binoculars over telescope is clearly the handiness. Telescopes are usually very heavy, less compact and more difficult to stow.

It is different with a pair of binoculars, which can quickly be stowed in the bag, so you do not have all the luggage full if you want to travel.

Another advantage is that you usually do not need a whole set of equipment to observe and start monitoring right away.

Astronomy binoculars with relatively small magnifications such as 10x can also be used well for observations in nature, without having to use a tripod.

If you have a steady hand, you can do without a tripod even with larger magnifications. It is not limited to astronomy.

Astronomy Binoculars Buying Guide

What to look for when choosing the best Astro binoculars to meet your night sky needs. Below are some fundamental things to look at when choosing between binoculars:

The angle of View/Field of View.

The field of view determines the width of your image. Therefore, for astronomers, it denotes the portion of sky you can cover when you target your binoculars at the stars. You should note! The wider the angle/field of view, the more sky you can capture.

Usually, powerful binoculars with high magnification tend to have a slender field of view and vice versa. A great Astro binoculars though will possess both a wide field of view and a good magnification.

Proper Magnification for Astronomical Binoculars.

Obviously, considering the fact that the stars, the moon, and galaxies are very far away, your choice of binoculars for astronomy might have to be those with higher magnification. Nevertheless, higher magnification also means an unstable image since every slight hand movement is also magnified 10x, 15x, or even 20x times.

Hence, to avoid such, you will have to either buy lower magnification binoculars (like 10x) or you get a tripod and use them on.

Objective Lens Size

This is the most significant feature of best binoculars for astronomy, together with magnification. The larger the lens, the more light that gets in thus, the brighter your image will be. Binoculars for astronomy should be at minimum 50mm to 70mm and above. Very common in astronomy are binoculars with larger lenses of 50mm to 100mm, mainly because they can amass more light.

Are they waterproof?

Remember that it is on a water planet that we live in. Sometimes water condenses on your binoculars. At times you accidentally drop them overboard or it rains. Hence, to consider waterproof binoculars may be of concern depending on where, how and when, where you plan to use them.



In this reviews the major points to consider when trying to find the ideal binocular for astronomy have all been discussed.

Everything but your choice is what’s left out. Regardless of how you explore it whether by the unaided eye, binoculars or telescopes; the night sky is a truly extraordinary place though we highly recommend you use a binocular.

With all that’s been said, all you need to do is hope for clear night skies to explore with the best binoculars for astronomy.
