Meteor Shower Photography Settings

There's no meteor-specific exposure setting to calculate, because a meteor is a random, unpredictable streak of light lasting a fraction of a second — the actual camera settings for meteor photography are identical to standard wide-field star photography, and the real technique is running hundreds of consecutive exposures over hours and hoping enough meteors happen to cross the frame during that window.

Settings Are Just Standard Star-Field Settings

A wide aperture, ISO in the 1600-6400 range depending on sky darkness, and a shutter speed at or just under your camera's NPF-rule trailing limit for the focal length in use — this is the exact same starting point covered on this site's general star-photography settings page, with nothing meteor-specific added. The genuine skill in meteor photography isn't in choosing a different exposure; it's in maximizing how much total sky area and total shooting time gets covered, since neither factor is something a single exposure setting controls.

Why Wide Focal Lengths Win for Meteor Showers Specifically

A meteor can streak across any part of the visible sky, not a predictable fixed point, so a wider field of view genuinely covers more sky area and statistically captures more meteors per hour of shooting than a narrower, more telephoto framing would, even though a telephoto shot of an individual meteor (if you happened to catch one dead-center) would show more detail. Most dedicated meteor-shower photography uses focal lengths in the 14-24mm range on full frame specifically for this wider-coverage advantage, not for any exposure-time reason.

Continuous Shooting Is the Actual Technique

An intervalometer set to fire the shutter continuously, back to back with the shortest possible gap between frames, for the entire viewing window — often several hours around a shower's predicted peak — is the real workflow. Most individual frames will show nothing but stars; a handful will happen to catch a meteor crossing during that particular exposure. Reviewing and keeping only the frames that actually caught something happens afterward, not during the shoot, since the meteor itself is over and gone in well under a second, far too fast to react to and trigger a shot manually.

The Radiant Point Matters for Composition, Not Exposure

Every meteor shower appears to radiate outward from a specific point in the sky (named after the constellation it sits in — the Perseids from Perseus, the Geminids from Gemini, and so on), and meteors nearer that radiant point tend to appear shorter, while ones farther from it streak longer across the frame. Framing with the radiant point somewhere in the shot, rather than centered, tends to produce a wider spread of usable meteor trails across the full frame rather than concentrating them in one small area near the radiant itself.

Timing Still Depends on Moon Phase and Location, Same as Every Other Target

A bright moon washes out fainter meteors just as effectively as it washes out faint stars and the Milky Way's core, so checking moon phase for a shower's predicted peak night matters as much here as for any other astro subject on this site — a shower peaking during a full moon will show meaningfully fewer visible meteors than the identical shower during a new moon, independent of the shower's actual underlying activity rate. The same light-pollution considerations covered elsewhere on this reference apply in full as well, since meteors are genuinely faint streaks competing with the same sky glow that washes out star detail.

Stacking Frames After the Fact for a Composite Image

Some photographers combine several of the best meteor frames from a single session into one composite image showing multiple trails radiating from the shower's radiant point at once — a genuinely different image from any single frame, and one that requires being upfront that it's a composite rather than presenting it as a single real exposure, since no one frame actually captured that many meteors simultaneously.
