How to photograph a meteor shower: settings, gear and the night's workflow

Gear: wide, fast, and on a tripod

The ideal meteor lens is wide and fast: 14–24 mm full-frame equivalent at f/1.8–f/2.8. Wide, because meteors appear across tens of degrees of sky and a tight frame mostly photographs empty blackness; fast, because a meteor writes its light in a fraction of a second — unlike stars, it gains nothing from longer exposures, only from a wider aperture. An f/1.8 prime records meteors more than twice as faint as an f/2.8 zoom.

The camera matters less than the lens. Any body with manual mode from the last decade works; high-ISO grace helps but stacking absorbs noise. The non-negotiables are a solid tripod, an intervalometer (built into most bodies; a $15 remote otherwise), two charged batteries (cold halves battery life), and a big memory card — a full night at 20-second frames is 1,200+ exposures.

A phone can play too: modern night modes on a small tripod, 15–30 second exposures, catch the brightest fireballs. Treat it as a fun second angle, not the main instrument.

Settings: the 20-second recipe

The starting recipe for a dark site: manual mode, aperture wide open, 15–25 second exposures, ISO 1600–3200, RAW format, white balance ~4000K (daylight-ish; RAW makes this reversible), long-exposure noise reduction OFF (it doubles the gap between frames — a meteor that lands in the gap is gone), and the intervalometer set to fire continuously with a 1-second interval.

Exposure length is a trade against star trailing: the old '500 rule' (500 ÷ focal length = max seconds) is a fine guide — about 25 seconds at 20 mm. Under a bright moon or suburban glow, drop to ISO 800–1600 or stop down slightly; the histogram should sit left of center but not crushed against the edge.

Focus is the step that ruins the most first attempts. Autofocus is useless in the dark: switch to manual, aim at the brightest star, magnify live view to maximum, and turn the ring until the star is a minimal point — then tape the ring. Check again after an hour; lenses drift as they cool.

Where to point: the radiant is a compass, not a target

Meteors trace back to the radiant, but near it their trails are foreshortened into stubby dashes. The longest, most photogenic trails appear 40–60° away from the radiant. So find the radiant's direction — every shower page and city page on this site gives it for your location and hour — and then aim your frame two or three fist-widths to either side of it, at 45–65° elevation where the sky is darkest and the airmass thinnest.

Composition beats pure sky: a treeline, ridge, barn or still lake anchors the image and turns a lucky frame into a photograph. Keep the composition identical all night — a locked tripod is what makes an honest composite possible later, and any bump restarts your alignment from zero.

If the Milky Way is up, let it share the frame with the radiant's flank; during the Perseids and Geminids this happens naturally and gives the classic postcard.

The night's workflow and the honest composite

Once firing, leave the camera alone — every adjustment costs frames, and reviewing images on the LCD wrecks both your dark adaptation and the sequence. The discipline of meteor photography is boredom: set it, verify one test frame, then go lie down and watch with your eyes. Expect meteors in perhaps one frame in fifty at a decent peak; a night can yield 10–40 meteor frames.

The famous images with dozens of meteors radiating from one point are composites, and there is an honest way to make one: keep the tripod fixed, align all frames on the stars (the sky rotates between frames), then layer only the meteor-bearing frames onto one base exposure. Because each meteor is placed where it truly appeared relative to the stars, the composite is a time-lapse of reality, not a collage. Disclose it as a composite — the picture is no less true for saying what it is.

One last physical tip: dew and frost kill more sessions than clouds. A cheap USB lens-warmer strip, or even a chemical hand warmer rubber-banded to the barrel, keeps the front element clear through the small hours.
