How to hold 10×50s steady

At 10× magnification, every small tremor in your hands is magnified ten times too. Here are four fixes, from free to cheap.

Brace your body. Tuck your elbows against your chest, or sit and rest them on your knees. Breathe out slowly and hold the view during the pause.
Lean on something. A fence post, a car roof or a door frame takes the weight off your arms. Pressing the binoculars' hinge against your thumbs and the top of your nose adds a third contact point.
Recline. A reclining lawn chair is the most underrated astronomy accessory. Lying back with your elbows on the armrests steadies the view and saves your neck for anything high overhead, such as tonight's Taurid radiant near midnight.
Mount them. Many 10×50s have a threaded socket on the hinge, usually under a cap, for a tripod adapter. It's the steadiest option, but a camera tripod is awkward for objects high in the sky, so it suits Moon and low-sky views best.

Try each method on the Pleiades. When you can count the stars without them jittering, you're steady enough.
