How to photograph the ISS
By Jeroen Wouda · 2 November 2026 · Basics
Photographing the space station is easier than it sounds, provided you accept what the picture actually is. You are not going to capture a spacecraft. You are going to capture a bright line, or a bright dot, against a sky, and the quality of the result depends far more on framing and foreground than on equipment.
The problem in one sentence
The exposure that makes the sky look right will not make the station look right, and the exposure that makes the station look right will give you a black frame with one white dot. Choose the sky, and let the station be a bright trail.
What you need
- A camera that lets you set exposure manually. A phone can work for a wide shot, within limits.
- Something to keep it still: a tripod, a wall, a beanbag on a car roof.
- A lens on the wide side. The station's path is long, and a tight frame loses it.
- A spot with a clear view in the direction of the pass, and something on the ground for scale.
- The pass details: entry direction, peak time, exit direction.
Know the path before you leave the house
The pass table tells you where the station will appear, when it peaks and where it goes. Sketch that on the sky with your hands before you set up, then frame wide enough to include both ends with margin to spare. Aim wrong by 30° and the pass happens entirely outside your frame, which is a common and entirely avoidable way to lose a night's work.
Focus before it gets dark
Autofocus needs contrast, and a dark sky full of faint stars gives it very little. Focus manually while there is still some light — on a distant building, a lit tower or the Moon — then tape the focus ring so it cannot drift. Check by zooming into the image on the screen rather than trusting the scale engraved on the barrel.
Set the exposure for the sky, not the station
Point the camera at the part of the sky the station will cross, and expose so that the sky has some tone and the skyline is visible. At dusk that means a blue sky rather than a black one, which is usually a much better photograph. The station, far brighter than anything else in the frame, will then record as a clean bright line or a saturated dot. That is the correct outcome, not a failure.
If you instead expose so the station is properly rendered — mid-grey rather than white — everything else falls into blackness and you are left with a lonely pixel on a void.
Three approaches
Single long exposure. Open the shutter as the station appears and close it as it fades. The result is one smooth arc. This is the simplest method and the one worth trying first. A very long exposure risks flattening the trail to a uniform white line and overexposing the sky, so it pays to experiment with the length.
Stacked frames. Take a series of shorter exposures through the pass and combine them afterwards. This keeps the sky under control and the trail even, and it preserves detail in the foreground. It needs a little software and a little patience.
Tracking. With a mount that follows the station — or a telescope on a driven mount — you can hold it in frame and record a dot rather than a line. This is genuinely hard: the pass is short, the path does not match the rotation of the stars, and the station stays small at any realistic focal length. Expect to miss the first several attempts.
Phone cameras
A phone on a steady support can record a bright pass as a faint line, if it has a night mode that allows a multi-second exposure. Do not expect detail: the sensor is small, the station is a point of light, and the result will be a line over a skyline. That is a perfectly good photograph if the skyline is interesting. Turn the flash off, and use the timer so that pressing the button does not shake the phone.
Mistakes worth avoiding
- Exposing for the station. You get a black frame with a white dot in it.
- Leaving autofocus on. It hunts in the dark, and you lose the pass to blur.
- Framing too tight. Wide is forgiving; tight is not.
- Starting late. You have a few minutes, and the brightest part is the middle.
- Shooting under a streetlight. It fogs the frame and kills the contrast.
- No foreground. A line in empty sky is a record, not a picture.
What makes a good picture
Context. A roof, a chimney, a tree, a person standing in a garden looking up. The station is small and featureless, so the picture works because of where it is and what it is passing over. The second ingredient is patience with the sky: dusk blue beats black almost every time, and it lets the viewer see that this is a real place at a real hour.
The station's brightness also changes through the pass, which is worth knowing when you frame the shot. It arrives faint, brightens towards the peak and then either fades away to the horizon or goes out abruptly if it enters the Earth's shadow. A trail that stops in mid-sky is not a mistake in your exposure: it is the station going dark, and it makes for an odd, honest image.
