When it comes to researching the market for a pair of good astronomy binoculars, many future stargazers enter the world of amateur night sky observing blindly, not knowing whether to go for binoculars, a monocular, or a telescope. To help you with this, I created a short guide for what is and how to choose the best binoculars for astronomy and stargazing for beginners for observing space, stars, planets, Moon, galaxies, star clusters, and nebulae. Next, I will tell you which factors are essential when choosing a pair of binoculars for astronomy and stargazing. Finally, I will give you some brief binoculars reviews of models I think you should consider. Happy stargazing and clear skies!

Astronomy Binoculars vs Telescope - Binoculars Advantages
Why would you choose a pair of binoculars over a telescope for visual stargazing? There are three main reasons:
Size — Small and Lightweight
Stargazing with binoculars is far easier and quicker to set up than using a telescope. Setup for astronomy with binoculars? Grab them, focus, and you are ready to go. They are easy to transport, and when using a standard, wide-field pair of ones, you don't need any tripod or mount — only your hands.
Wider FOV (Field of View) — Easier to Find Objects on the Night Sky
Suppose you are not familiar with the night sky yet. In that case, a pair of wide-field binoculars is your best way to learn your first constellations (like the Orion constellation), stars (e.g., Betelgeuse), and some deep-sky objects like nebulae, star clusters, or galaxies. Less zoom — easier to orientate where you are gazing right now.
Price — far Less Expensive than a Telescope
When buying a telescope, you have to acquire some additional accessories:
- Tripod
- Mount
- Diagonal mirror
- Eyepieces
For example, when purchasing a pair of binoculars for astronomy, you are ready to go stargazing right after unboxing them.
And not to mention that 'raw' telescopes (OTAs — optical tubes) are generally far pricier than binoculars.
What do Those Numbers (10 x 50, 15 x 63, etc.) Mean?
The first parameter is the magnification (how many times closer the subject is to you — 7 times closer, eight times closer, ten times closer)
The second is objective lens diameter (in millimeters; the bigger the light gathering capabilities).
So, a pair of binoculars marked as 10 x 50 has 10x magnification and 50 mm objective lens diameter.
For astronomy, the bigger the objective diameter, the better — bigger objective diameter means more light gathered, thus more faint night sky details visible for a human eye. Unfortunately, although the bigger the lenses are, the heavier they become — it's crucial if you want to operate your binoculars handheld-only without a tripod.
10 x 50 — Universal Binoculars
The 10 x 50 is considered the 'standard' ratio for binoculars in general. It's a perfect combination of usable field of view, nice speed (in terms of light transmission through the glasses), and weight. 10 x 50 is a universal combination for any applications — birdwatching, outdoor, tourist, hunting, or military. You can use binoculars with those parameters handheld, without a stabilizing tripod. It's a good starting point for a beginner stargazer.
7x - 8x Magnification (7 x 50) — Widefield Models Designed for Astronomy
For handheld wide-field astronomy, you may find that models with lower zoom (7x, 8x) perform better. They are easier to operate with hands without shaking, they reveal more details, and you can see more celestial objects at once due to the wider field of view. They are perfect for beginners to get familiar with the night sky — both adults and kids.
