Astronomy Binoculars Buying Guide


If you want to take a trip through space without ever having to leave Earth, you can view the night sky with a pair of binoculars right from your deck on a dark, clear night. While other binoculars may be able to do the job, you will get the most out of this experience by using astronomy binoculars that are specially designed for this purpose.

The Popularity of 10×50 Astronomy Binoculars

There are several reasons the 10 x 50 astronomy binoculars are the most popular for stargazing. They have a larger aperture which allows more light to get in than a regular 42mm. It is also small enough that you can carry it easily in the field when you are using it for terrestrial viewing.

The 10x power means that objects you are viewing will appear ten times closer than what they appear with the naked eye. The exit pupil of 5mm is good for night time use also. It may not be as powerful as the 10×70 but it tends to be more popular due to the size, ease of use, and it is less expensive than most 10x 70s.

Benefits of a Tripod and/or Tripod Adapter

If you have been outdoors using binoculars for any length of time you will already know why it is a good idea to purchase a tripod for your binoculars and to make sure that the pair you buy has a tripod adapter.

If you are doing any stargazing or long-range viewing and plan on being out for a long time, your arms are going to get tired. Having a good quality tripod will allow you to view for long hours hands-free so you don’t have to put up with the tired arms and shoulders. Having a good tripod will also make sharing the views much easier.

When choosing a pair of astronomy binoculars make sure that they can be attached to a tripod via a tripod adapter or that they come with one already. You will enjoy extended viewing that much more and your arms and shoulders will thank you!

I Like Big Apertures and I Cannot Lie – Now Here’s Why:

If you are new to using binoculars you may not understand what the big deal is about aperture size. The aperture size is indicated by the second number that is displayed. For example, a 10x 50 pair of binoculars has a decent sized aperture, indicated by the 50; the larger the number the larger the aperture. So what does a large aperture provide?

  • Allows More Light In – When you are doing night viewing, you want as much light as possible to get inside so you can have a clear picture of what you are trying to look at. The larger the aperture is the brighter your images will be. Anything under 50mm will make night viewing virtually impossible.


  • Higher Optic Quality – Optic quality is important when it comes to the longevity and clarity that your binoculars will have. The prisms, type of glass, and materials used in constructing the binoculars will always be stronger and better when higher optic quality is the manufacturer’s objective. If you are just wanting binoculars for casually watching the birds in your yard, then no, higher optic quality really doesn’t matter. For astronomy use, however, the quality of the optics that the binoculars have can provide you with an incredible viewing experience that will have you hooked on night star gazing for good.

Comparison: Binoculars VS Telescopes

So how do you know which is better to buy for astronomy; telescopes or binoculars? Below we have listed out the major differences between the two so you can decide for yourself which you prefer.

Telescopes are most often used for astronomy and stargazing. They can view exceptionally long distances and have a complicated optical system that collects light and uses mirrors and other methods to bring images that are far away, closer so you can see them.

Years ago, binoculars were used more for bird watching, spying on people, and other more casual activities but modern binoculars have improved so much and added new technology so that a high-quality pair of binoculars can offer a view of the night sky that rivals some telescopes.

The zoom capabilities with a telescope are very long, typically 12x to 15x on a basic telescope and can go as high as 45x to 60x. Binoculars start with a low zoom of around 4x and can go up to 12x or higher if they are specialty binoculars.

Field of view is another place that binoculars and telescopes differ. While the telescope typically has a narrow field of view, binoculars can have a very wide field of view, opening up a lot more viewing space for you to enjoy. This wide field of view is good for long range viewing as well.

Unless you just like to carry around a lot of equipment, you will love the portability of binoculars over the bulkiness of a telescope. Telescopes are also not suitable for daytime viewing of nature which limits you to only astronomy.

Binoculars can be carried around in your pocket in many cases, and in easy to carry cases if they are a little larger. This portability allows you to be spontaneous in your viewing and catch things that you may not have been able to, had you only had a telescope to work with.

Pros of Binoculars Rather Than Telescopes

  • Navigating is less frustrating for a beginner
  • Wider Field of View
  • Observation with both eyes feels natural
  • Portability
  • Two Barrels collect more light-it is like seeing in stereo!
  • Lower learning curve for beginners
  • Cost is typically lower for binoculars over telescopes

Cons Binoculars Rather Than Telescopes

  • Lower Magnification
  • Truly need a telescope for the most clear astronomical views
  • Nighttime viewing is not as strong or clear for binoculars as it is for telescopes


There are many different types of binoculars on the market. Not all of them are ideal for astronomy so it is important that you look for the models that will give you the magnification and aperture you want. You do get what you pay for, so while we are not suggesting you go out and purchase the most expensive pair you can find, what you should NOT do is look for “cheap”.

A cheap pair of binoculars will operate and perform cheaply and you will be disappointed in the quality and results you get. Look for binoculars that have high magnification, high power, high optical quality, and that come from a reputable company.

Look at the customer comments and reviews and see what others are saying about using the binoculars you are interested in. This is a great way to gain inside knowledge and information about any binoculars you want to purchase.

In many cases, you may not get a pair of binoculars that are better than a telescope but if you are just starting out with stargazing, binoculars are an excellent place to start. If you choose a high powered pair of binoculars, be sure to invest in a tripod or tripod adapter so you can hold them still properly. This will make a big difference in the quality and sharpness of your images.

Once you purchase your binoculars, take the time to go through the manual and read it thoroughly. It will help you understand the different features and functions your particular binoculars have so when you take them out that first night, you will be thrilled with what they allow you to see.
