Start With Binoculars
Before you buy any telescope, buy a pair of binoculars — or reach for the ones in your closet. They are the best-value tool in all of astronomy, the easiest to use, and the only piece of gear you will never regret owning, even after you own a telescope.
The purchase you'll never regret
A telescope is a commitment; binoculars are a gift you give yourself. They cost a fraction as much, weigh almost nothing, need no setup, survive being tossed in a bag, and show you both eyes' worth of a wide, comfortable, right-way-up view. Crucially, they teach you the sky — you learn where things are, which is the skill that makes a telescope worth owning later. And when you do get a scope, the binoculars stay in rotation for wide sweeps of the Milky Way that no telescope can frame.
What "10×50" means
Every pair of binoculars is labelled with two numbers, like 10×50. The first is the magnification (10×). The second is the aperture in millimetres (50 mm) — the size of the front lenses, and, just as with telescopes, the thing that gathers light. For astronomy you want enough aperture to pull in faint objects, and low enough magnification to hold the view steady in your hands.
Best all-rounder
10×50 — the classic astronomy pair; bright, steady, affordable
Also excellent
7×50 and 8×42 — very steady, wide, great in the dark
Big & deep
15×70 — shows more, but really needs a tripod
Rough cost
A solid pair starts around $60–120
Beyond about 10× the shake of your own pulse and breathing blurs the view, so bigger magnification usually means a worse experience unless you mount them. A tripod adapter (a few dollars) transforms any pair.
The one skill that doubles what you see
A shaky view hides more than a small aperture does. Brace your elbows against your chest or a fence, sit in a reclining chair and rest them against your brow, lean back against a wall or car, or fix them to a photo tripod with a cheap L-adapter. Steady binoculars reveal fainter stars and more detail instantly — it is the single biggest upgrade you can make, and it's free.
A tour with just your binoculars
- The Moon — craters, dark maria, and mountain ranges along the terminator; stunning even at 10×.
- Jupiter's moons — the four Galilean moons as tiny stars beside the planet, shifting night to night. Galileo's own discovery, in your hands.
- The Pleiades — the Seven Sisters cluster explodes from six naked-eye stars into dozens of blue jewels.
- The Andromeda Galaxy — the nearest big galaxy, a soft oval glow 2.5 million light-years away — the farthest thing most people ever see with their own eyes.
- The Orion Nebula — a misty patch in Orion's sword, a nursery of newborn stars.
- The Milky Way — sweep along it from a dark site and it dissolves into countless stars and glowing clouds.
- Comets & meteor showers — bright comets show their tails, and binoculars deepen the color of a fireball. (For meteor showers, though, use your naked eyes — binoculars are too narrow.)
