Astrophotography vs. Astronomy

What is Astronomy?

Astronomy is the scientific discipline dedicated to studying celestial objects such as stars, planets, galaxies, and cosmic phenomena such as black holes and supernovae. It involves theoretical modelling, data analysis, and observational techniques to understand the universe’s origins, structure, and evolution. Astronomers rely on a wide range of tools, including optical telescopes, radio observatories, and space-based instruments such as the Hubble Space Telescope.

    • Use the iPhone’s Night Mode (available on iPhone 11 and later models).
    • Set exposure time to the maximum (up to 30 seconds with a tripod).
  2. Manual Controls:
    • ISO: Start at 800–1600. Adjust based on aurora brightness.
    • Focus: Use manual focus in compatible apps. Set to infinity or focus on a bright star.
    • Shutter Speed: Adjust to match the aurora’s activity. Use shorter times (3–10 seconds) for fast-moving auroras.
  3. HDR Settings: Enable HDR mode for better contrast and dynamic range.
  4. RAW Capture: Use apps that support ProRAW to retain more details for editing.

Photographing Auroras

  1. Set Up:
    • Mount the iPhone on a tripod and stabilise it.
    • Frame the shot to include foreground elements for composition.
  2. Use Night Mode or Long-Exposure App:
    • If using Night Mode, let the iPhone calculate exposure time but keep it stable.
    • In apps such as NightCap, manually adjust settings for ISO and shutter speed.
  3. Take Multiple Shots:
    • Shoot continuously to capture the dynamic changes in auroras.

Capturing Aurora Videos

  1. Use Native Camera or Apps:
    • Use the iPhone’s native camera in low-light mode or an app such as FiLMiC Pro for better manual control.
  2. Settings:
    • Set a high ISO (1600–3200) and adjust shutter speed for the chosen frame rate.
    • Keep the video resolution high (4K if available) for better quality.
  3. Stabilisation:
    • A tripod is essential to avoid shaky footage in long-exposure videos.

Tips for Both DSLR and iPhone Aurora Photography

  1. Plan Ahead:
    • Check aurora forecasts using apps such as My Aurora Forecast or websites such as SpaceWeather.
    • Choose a location with minimal light pollution and a clear northern or southern horizon.
  2. Scout Your Location:
    • Arrive early to find a good vantage point.
    • Include natural or man-made elements in your composition.
  3. Protect Your Equipment:
    • Use hand warmers or lens heaters to prevent condensation in cold environments.
    • Carry extra batteries, as they drain quickly in low temperatures.
  4. Experiment with Settings:
    • Auroras vary in brightness and speed, so adjust settings dynamically.
    • Take test shots and refine based on the results.
  5. Post-Processing:
    • Use editing software such as Adobe Lightroom or Snapseed to enhance colors, reduce noise, and adjust exposure.

Interesting Night Sky Targets

The night sky offers a plethora of objects and phenomena for astrophotographers of all skill levels.

Solar System Objects

  • Moon: Capture its craters and phases; use a telescope or telephoto lens.
  • Planets: Photograph Jupiter’s cloud bands, Saturn’s rings, or Mars’s polar caps.
  • Comets: Look for comets with bright tails and track them over multiple nights.

Deep-Sky Objects

  • Nebulae: The Orion Nebula (M42) and the Rosette Nebula are vivid targets.
  • Galaxies: Andromeda (M31) and the Pinwheel Galaxy (M101) are popular.
  • Star Clusters: Capture the dazzling Pleiades (M45) or globular clusters such as M13.

Transient Events

  • Meteor Showers: Annual events such as the Perseids (August) and Geminids (December) provide opportunities to capture meteors streaking across the sky.

Eclipses: Both lunar and solar eclipses are rare and dramatic phenomena.

Enhancing Astrophotography with Post-Processing

Post-processing is an integral part of astrophotography, transforming raw captures into stunning final images.

Software

  1. Adobe Lightroom/Photoshop: For global adjustments and noise reduction.
  2. DeepSkyStacker: Combines multiple exposures to enhance signal-to-noise ratio.
  3. PixInsight: Advanced processing for deep-sky images.

Techniques
