The 10 Best Astronomy Binoculars

For most stargazers, the Celestron SkyMaster Pro 15x70 hits the sweet spot between a big view and a pair you can still carry outside. Its large front lenses pull in faint star clusters and the dusty Milky Way. The sealed, nitrogen-filled body shrugs off dew and damp grass, and the optics hold their alignment well. A rail on top helps it balance on a tripod, which you'll want for any session longer than a few minutes.

If you want big binoculars for little money, the Celestron SkyMaster 15x70 has been the usual first choice for years. Its wide lenses gather enough light for star clusters, bright nebulae and the moons of Jupiter, and the eyecups leave room for glasses. The trade-offs are real. The plastic tripod adapter flexes, the body isn't sealed against moisture, and the two halves can drift out of line, which makes stars look doubled until it's adjusted.

Serious observers who want one pair to keep for decades should look at the Celestron Echelon 20x70. BestBinocularsReviews has named it its top high-end astronomy pick since 2015. Each eyepiece focuses on its own, which suits a pair that stays set up on a tripod, and the sealed body stands up to dewy nights. It ships in a hard case. The cost is steep, it's heavy enough that a tripod isn't optional, and stock comes and goes.

The Vortex Diamondback HD 10x50 suits stargazers who want to hold their binoculars rather than mount them. Its wide field frames whole star patterns, the Pleiades and the Andromeda Galaxy, and it's light enough to use for an hour at a dark site. It's sealed against water and fog, and Vortex's lifetime warranty covers damage with no receipt required. At this power it shows less faint detail than a big pair on a tripod.

Think of the Celestron SkyMaster 20x80 as a small wide-field telescope you look through with both eyes. Its big lenses pick out galaxies and globular clusters that smaller pairs only hint at, and a long bar under the body lets it balance on a tripod. It comes with a soft case. Holding it by hand is out of the question, the body isn't sealed, and like other budget giants it can need realigning.

The Celestron SkyMaster Pro 20x80 brings a sealed, nitrogen-filled body and Celestron's better lens coatings to a big-lens pair. A rail on top lets you slide it forward or back until it balances on the tripod head, so it doesn't droop when you aim high. The field is narrow, so finding targets takes some practice. The eye relief is short for glasses, and it's heavy enough to tip a light photo tripod.

For the biggest view you can get without buying a telescope, look at the Celestron SkyMaster 25x100. Its huge lenses show faint nebulae and pack the view with stars, and each eyepiece focuses on its own, so you set it once for your eyes. A built-in rod attaches it to a tripod. It's far too heavy for hands or a light tripod, so plan on a stout tripod or a parallelogram mount, and the body isn't sealed against moisture.

The Celestron Cometron 7x50 is a cheap way to find out whether you enjoy scanning the night sky. Low power and a very wide field make it simple to sweep along the Milky Way and hop between constellations, and it's light enough for older kids to hold. The prisms use a lower grade of glass, so the view dims toward the edges and stars there look soft. It shrugs off a light drizzle but isn't waterproof.

As the update to Nikon's long-running Aculon line, the Nikon ACTION 10x50 keeps the classic Porro shape that many amateur astronomers prefer for handheld stargazing. The field is generous, so big clusters and rich star fields fit comfortably, and the eyecups twist out or down to suit glasses. It threads onto a standard tripod adapter. Owner feedback is still thin, and sellers disagree on how well it's sealed, so keep it out of the rain.

The Vortex Triumph HD 12x50 adds a little more reach in a light, sealed body for anyone who'll mostly hold it by hand. It pulls the Orion Nebula and the craters of the Moon a bit closer, and Vortex's lifetime warranty covers drops and other accidents. At this power every heartbeat shows in the view, so brace it on a fence, a car roof or a tripod. Its coatings are a simpler grade than Vortex's pricier lines.
