How to Photograph the ISS: Exposure, Focus & Camera Setup

Updated September 19, 2026 · 6 min read

The ISS looks like a bright, fast star, so there is a certain way to photograph it: your technique has to match its movement. At up to about a degree of sky each second, the station crosses more of the sky than any comet, and it is gone from horizon to horizon in minutes — but the basics are far more forgiving than deep-sky astrophotography.

What you get is a clean, straight streak of a bright object — its track across the stars — and with modest equipment that is already a genuinely good result.

Set expectations first

At over 400 km away, even a long telephoto shows the ISS as a small, bright point — rarely more detail than a few pixels unless you go into specialist territory (hundreds of millimetres of focal length plus very fast shutter work). The realistic, satisfying goal for most of us is the streak: a straight line across the star field, unmistakable and easy to frame.

For that, the equipment is simple: a phone or any camera on a tripod, a clear sky, and the pass prediction.

Start with your phone

A modern smartphone camera is genuinely enough for a first ISS photograph.

Put the phone on a tripod — or any stable position, propped or wedged against a ledge.
Use night mode if your phone has it; it will happily hold a multi-second shutter.
Keep the wide lens; the station is bright and a wide field makes aiming forgiving.
Start shooting a couple of minutes before the pass time, and keep the shutter rolling.
Expect a short, bright streak across a dark frame — exactly what it looks like in person.

The result reads immediately as "space station crossing the sky" — usually all anyone needs.

The classic setup: camera on a tripod

For a longer, brighter streak, the routine is the same long-exposure recipe astrophotographers use for star trails:

Mount the camera on a tripod, fully manual mode.
Focus at infinity (see the focus notes below).
Compose the frame for the path of the pass, not for where the station is at the start.
Aim the first exposure to start just before the predicted time, so you capture the full crossing.
Make each exposure 10-30 seconds; the ISS draws one continuous straight line across each frame.

Because the station moves, stars will trail slightly in the same frame — that is normal and usually welcome.

Focus and exposure numbers

Focus: switch to manual and focus at infinity. Autofocus will hunt on a dark sky and fail at the moment that matters. On many lenses, focus on a distant bright object (Moon, bright star, distant building) first and lock it there.
Aperture: wide open to about f/4 — you want maximum light and a short, bright streak.
ISO: low-ish (around 400-1600 on modern cameras) so the star field stays clean.
Shutter: 10-30 seconds — long enough for a visible streak, short enough to keep other light out of the frame.
Turn off stabilisation on the tripod; it fights against the mount.

For telephoto shots (200 mm and up), shorten the shutter so the station does not smear across the whole frame — at 200 mm, a one-degree-per-second object crosses the frame in seconds.

Compose using the pass prediction

The framing should be planned from the prediction, not guessed at check time:

The prediction states the start direction and maximum elevation — translate those into a spot on the sky and aim there.
Wide-angle (or phone): aim at where the pass peaks; the streak will be short but well placed.
Telephoto: you are going to chase a moving point — keep horizon landmarks in the corners of the frame to judge where to swing.
Not sure which columns mean what? The reading a pass prediction guide explains elevation and direction.

Aim for a pass above about 40° elevation on your first attempt — the streak will be bright and the geometry simple.

Going further: telephoto and tracked mounts

To go from streak to something structured takes focal length and speed. At 400-800 mm, a fast exposure (around 1/250 s and shorter through a fast telescope or long lens) freezes the ISS enough that a bright, elongated dot is the realistic bar. Resolving the solar arrays needs focal lengths around a metre and a tracking mount — specialist solar-system astrophotography territory.

Realistically, chasing the streak on a tripod is attainable tonight, for anyone, and it photographs gratifyingly well. Everything beyond that is a rewards-versus-effort decision — start with the tripod.

Once you’ve photographed it, the same prediction habits turn you into a reliable observer: how to see the ISS covers the pure eyes-on version.

Before anything else you need a pass worth pointing a camera at.
