The nights are drawing in, bringing more opportunities to observe the wonders of the night sky. If you want to get a closer look at the moon, planets and deep sky objects without the hassle of transporting or setting up a telescope, we’d recommend a pair of large astronomy binoculars. One of our top picks, the Celestron SkyMaster 15×70, is great quality, relatively lightweight and although they were cheaper during Prime Day, Amazon are still offering the cheapest price. Our optics writer bought them last year and uses them regularly. However, if you can stretch your budget a little further, the Celestron SkyMaster 20×80 are now even cheaper than they were during Prime Day.
These 15x70s strike a perfect balance of price, portability and performance, treating us to beautiful views of the moon, Andromeda Galaxy, Jupiter and its four Galilean moons and the Pleiades during our full Celestron SkyMaster 15×70 review, where we gave them 4 out of 5 stars.

While there is some chromatic aberration around brighter objects like the moon (which is to be expected at this price point), we had hours of fun with these binoculars, and they’re a fantastic option to get a better look at the upcoming supermoons on November 5 and December 4 without breaking the bank.
The 15x magnification and large 70mm objective lenses are a fantastic combination for stargazing, but a magnification this high, combined with their size and weight, means they’ll need to be mounted on a sturdy tripod to prevent shaky views. Luckily, a tripod adapter is included, alongside lens caps, a rainguard, a carrying case, neck strap, lens cloth and instructions. They’re waterproof, but not fogproof, which is good if you get caught out in the rain, although we wish it were the other way around, given their intended use. Still, we’ve never had too much trouble with them fogging up.
If their size and weight are a dealbreaker, you can still get great handheld views of the night sky with a pair of compact binoculars, but they won’t have as powerful a magnification. Or, if you want to invest a bit more, a pair of the best image-stabilized binoculars will prevent shakes at higher magnifications.
Key features: 15x magnification, 70mm objective lenses, water-resistant, 18mm eye relief, 52.5 feet (16m) close focusing distance.
Price history: They were down to $75 during Prime Day, but this is still the cheapest price we’ve seen them against the other retailers today.
Price comparison: Amazon: $99 | Walmart: $109.99 | B&H: $109.99
Reviews consensus: Combining performance, price and portability, they’re a brilliant option for beginners or anyone on a budget, and we actually preferred their handling compared to the Celestron SkyMaster 15×70 Pro ED.
