Astronomy Binoculars Buying Guide: A Few Words on Tech Specs and Features
Before you buy any astronomy binoculars, you should know that they are not telescopes and will probably never reveal you the deep space mysteries some telescopes for beginners or advanced astronomers do. Never mind the Hubble. Before you start buying any type of binoculars, magnifying glasses, spotting scopes, telescopes for kids or beginners, and even microscopes, you need to first understand how optical devices work and what their tech specs mean. Moreover, since you are looking for the best binoculars for astronomy, you should also learn more about the various types of telescopes, lenses, and focal powers you should expect from a device you buy.
If you wonder why you would get a pair of astronomy binoculars instead of an astronomy telescope, the answer falls under the practicality umbrella.
- Binoculars are portable and easy to carry anywhere. While you won’t probably take a telescope to a rock concert, football game, or the forest, you can bring the binoculars for an exquisite viewing experience.
- Binoculars are versatile enough to allow you some stargazing along with other hobbies you might want to try: birdwatching, wildlife observations, hunting, crowd surveillance, teaching optics in a classroom, and more.
- Astronomy binoculars, in particular, can lay the foundation for a lifetime stargazing hobby without losing their usefulness even if you move onto a telescope for advanced astronomers.
All in all, you can throw your astronomy binoculars in any backpack and use them anytime, anywhere, and for forever reason. Now that we cleared that up, let’s discuss some of the tech specs and features we mentioned on each product review so you know what best fits your needs!
Astronomy Binoculars Magnification and Aperture
When you looked at our products above, you saw a set of numbers along the lines of 12X42 or 7X50. The first number in the pair is the magnification (or power), while the second is the aperture (the diameter of the lenses measured in millimeters).
If you want to learn more about these specs, check out our guide on how to buy telescopes, as they feature the same tech specs!
Field of View
Most times, you will see the field of view expressed in feet at a distance of 1,000 yards. The FOV specification tells you how wide you will see a certain scene. These days, FOV is also shown in degrees, but the conversion is simple:
- 1 degree equals 52 feet at 1,000 yards.
Never expect astronomy binoculars’ field of view to compare to that of telescopes. Adjust your expectations accordingly, and you will enjoy an excellent experience.
The exit pupil describes a virtual aperture in an optical device. On your binoculars, the exit pupils are those small bright disks you look through. It is an important tech spec because it allows you to understand how much light will reach your eyes.
- The larger the exit pupil diameter is, the more amount of light your eye will gather. It is of particular importance when you look for the best binoculars for astronomy because you need to use them also in poor light conditions, like dusk or dawn.
This feature pertains to the eyepieces’ design when it comes to binoculars. It describes the ideal distance between your eyes and the eyepieces. You want astronomy binoculars with long eye relief measurements so you can comfortably see the entire picture, not just the center of it.
- Eye relief distances are also of great importance for people who wear glasses, so you should take your time and check each binoculars model that best suits your needs.
Astronomy Binoculars Lens Coatings
When you show interest in telescopes and binoculars, you learn soon enough that lenses receive a few millionths of an inch thin magnesium fluoride layers to prevent light reflection. The better and more coatings your lenses feature, the better the images will be.
- Most binoculars for astronomy feature fully coated, multi-coated, or fully multi-coated lenses.
What you should know is that the better the coatings, the more expensive the binoculars will be.
Porro Prisms and BAK-4 Glass
In the field of optics, the Porro prism, taking its name from its inventor Ignazio Porro, is a reflective prism meant to alter an image’s orientation.
Porro prisms were and still are the standard in binoculars manufacturing.
- Today, you will find Roof prisms as well – on the high-end side of the price spectrum.
- However, the Porro design is simpler, more light efficient, and with better contrasting images.
Here are some more things you should know about prisms when you buy binoculars, as without them, you would just wear a pair of magnifying glasses over your eyes.
Porro prism binoculars have objective lens tubes that are offset from the eyepieces; the prisms angle from the eyepieces to the objective lenses. Roof prism binoculars have two straight tubes, making them smaller and more compact. Porro prism binoculars usually have a higher quality image and less light loss (which makes the picture clearer). Although roof prism pairs can absolutely have a comparable optic, their compact design and complex prisms make the higher-priced roof prisms a better bet for a quality binocular.
Before you decide if you are going to be Team Porro or Team Roof, make sure you choose your astronomy binoculars depending on your astronomy levels that you have to match with the device’s price/value ratio. Porro prism designs offer better performance for the money. The high-quality ones also feature BAK-4 optical glass, a standard for some of the best binoculars for astronomy on this list.
If you are a beginner or intermediate astronomy enthusiast and you do not want to invest in a telescope just yet, Porro prism astronomy binoculars will show you the way to quitting the hobby, or, on the contrary, develop on it with upgraded pieces of equipment.
