How to Photograph the ISS and Satellites: A Beginner's Guide

When it is visible, NASA describes the International Space Station as the brightest object in the night sky other than the Moon. Traveling at 28,000 km/h, it crosses the sky in just 3-6 minutes, a brilliant, steady point of light moving purposefully among the stars. And you can photograph it with gear you probably already own.

Beyond the ISS, many satellites are visible to the naked eye on a clear night. Starlink satellite trains and dozens of other spacecraft create streaks and points of light that make for compelling photographs. Here's how to capture them.

What You Need

Minimum Equipment

• Camera: Any camera with manual exposure controls. A DSLR or mirrorless camera is ideal, but even a smartphone with a manual/pro mode or night mode can capture bright passes.
• Tripod: Essential. Even short exposures (1-2 seconds) will blur handheld. A basic $20 tripod works fine.
• Wide-angle lens: A 14-24mm lens captures a large swath of sky, making it easier to frame the satellite's path. Kit lenses (18-55mm) work well at their widest setting.

Recommended Additions

• Intervalometer or remote shutter: Triggers the shutter without touching the camera, preventing vibration. Many cameras have built-in interval shooting or can use smartphone apps as remote triggers.
• Fast lens: f/2.8 or wider gathers more light, allowing shorter exposures and capturing fainter satellites.
• Telescope with tracking mount: For resolved ISS images showing the station's structure, you need a telescope (8" or larger) on a motorized mount that tracks the ISS across the sky. This is advanced technique.

When and Where to Look

Satellites are visible when they're illuminated by the Sun while the observer is in darkness, typically during the 1-2 hours after sunset and before sunrise, when the satellite is high enough to catch sunlight but the ground is in shadow.

Essential Apps and Websites

• Heavens-Above (heavens-above.com): The gold standard for satellite pass predictions. Shows exact times, brightness (magnitude), and sky paths for the ISS and hundreds of other satellites.
• ISS Detector (Android/iOS): Mobile app with push notifications for bright ISS passes over your location. Includes augmented reality view showing exactly where to look.
• Stellarium (desktop/mobile): Planetarium software that can overlay satellite positions on a realistic sky view.
• N2YO.com: Real-time satellite tracking with pass predictions.
• SpaceNexus Satellite Tracker: Track satellites and get pass predictions from our integrated satellite tracking module.

What Makes a Good Pass

• Brightness: ISS passes vary from about magnitude -4 (brilliant, comparable to Venus) to about +2 (dim). Aim for passes brighter than magnitude 0.
• Elevation: Higher passes (above 45 degrees) are brighter and easier to photograph. A 90-degree (overhead) pass is ideal.
• Duration: Longer passes (4+ minutes) give you more time to shoot and produce longer trails.
• Direction: Knowing the satellite's path lets you compose your shot in advance.

Camera Settings

For Satellite Trails (Streaks Across the Sky)

• Mode: Manual (M)
• ISO: 400-1600 (start at 800)
• Aperture: Wide open (f/2.8 or as wide as your lens allows)
• Shutter speed: 15-30 seconds for trail shots. The satellite will appear as a bright streak across the frame.
• Focus: Manual focus to infinity. Use live view to focus on a bright star, then lock the focus ring with tape.
• White balance: Daylight or auto (shoot RAW for flexibility).
• File format: RAW for maximum post-processing control.

For Multiple Exposures / Stacking

• Shutter speed: 2-5 seconds per frame
• Interval: Continuous shooting or 1-second interval between frames
• Stack in post: Combine frames using StarStaX (free), Photoshop (lighten blend mode), or Sequator to create a composite showing the satellite's full path as a dashed or continuous line.

For Resolved ISS Images (Through a Telescope)

• Telescope: 8" or larger reflector or SCT
• Tracking: Manual tracking or computerized GoTo mount with satellite tracking capability
• Camera: High-speed planetary camera (ZWO ASI series) recording video at 100+ fps
• Processing: Stack the best frames from video using AutoStakkert or RegiStax. With good seeing conditions and a 10"+ scope, you can resolve the ISS's solar panels, modules, and even docked spacecraft.

Photographing Starlink Trains

Newly launched Starlink satellites are visible as a "train" of bright points moving in a line across the sky during their first few days in orbit, before they raise their orbits and become fainter. These trains are spectacular photographic subjects.

• Timing: Best within 1-5 days of launch, during the first and last hours of darkness.
• Settings: ISO 1600, f/2.8, 10-15 second exposures. The train will appear as parallel dashed lines.
• Tracking: Use the "Starlink" satellite group on Heavens-Above or dedicated Starlink tracking sites like findstarlink.com.

Composition Tips

• Include foreground: A satellite trail alone is a line on a black background. Add trees, buildings, monuments, or landscapes for context and visual interest.
• Scout the location: Know the satellite's path in advance and position yourself so it passes over an interesting foreground element.
• Capture the Milky Way: In dark sky locations, satellite trails through the Milky Way create stunning composites.
• Time-lapse: Set your camera to continuous shooting and compile frames into a video. The satellite's motion becomes dramatically visible.
• Plan for twilight: Some of the best satellite photos are taken during deep twilight when the sky retains color but is dark enough for satellites to be visible.

Post-Processing

• StarStaX: Free tool for stacking multiple exposures into a single star trail / satellite trail image.
• Adobe Lightroom: Adjust exposure, contrast, and color of individual frames. Reduce noise from high ISO.
• Sequator: Free stacker for Windows that can align stars while preserving satellite trails.
• RegiStax / AutoStakkert: For telescope video, stack the sharpest frames to create detailed ISS images.

The ISS orbits at an inclination of 51.6 degrees, and NASA says its path passes over more than 90 percent of Earth's population. On any clear evening, you're likely within a few hours of a visible pass. All you need is a camera, a tripod, and a clear sky.
