1. Essential Equipment for Astrophotography
To embark on your astrophotography journey, certain equipment is indispensable. These tools are crucial for capturing the faint light of stars and celestial objects:
1.1. Tripod: The Foundation of Sharp Images
A sturdy tripod is non-negotiable. It allows for the long exposures necessary to capture stationary stars, typically with shutter speeds of up to 30 seconds. Without a tripod, images will be blurry due to camera shake.
1.2. Camera and Lens: The Light-Gathering Duo
-
Aperture: Opt for a camera and lens with a wide aperture, ideally between f/1.4 and f/4. This wider opening allows more light to enter the camera, crucial for capturing faint celestial objects.
-
Focal Length: A wide-angle lens is preferred. On a full-frame camera, a focal length of 14-24mm is ideal, while a crop sensor camera benefits from a 10-18mm lens. The wider the focal length, the more of the Milky Way you can capture, though it may appear smaller in the frame.

A popular choice is the Sony 24mm f/1.4 GM lens, favored for its ability to make the Milky Way appear larger. However, the composition might sometimes dictate the need for a wider lens.
1.3. Illumination Tools: Navigating the Darkness
A torch or head torch is vital for navigating in the dark and for setting up your equipment safely.
1.4. PhotoPills App: Your Celestial Guide
The PhotoPills app is an invaluable tool for planning your astrophotography shoots. It helps you determine the position of the Milky Way in the sky at your location and desired time. For a one-off fee, this app can significantly improve your chances of capturing stunning images.
2. Planning Your Milky Way Shoot
Effective planning is key to successful astrophotography. Consider these factors:
2.1. Moon Phases: Timing is Everything
Always check the moon phases before heading out. A new moon (or a night close to it) provides the darkest skies, allowing the stars to shine brightly.
2.2. Utilizing the PhotoPills App: Precise Positioning
The PhotoPills app is also crucial for determining the direction and height of the Milky Way at any given time, as well as the rise and set times of the sun and moon.
2.3. Balancing the Moon and Milky Way
While a new moon is ideal, shooting with a small amount of moonlight can sometimes enhance the foreground. Up to 30% moon visibility is acceptable if the moon is low and behind you, providing subtle foreground lighting. However, avoid shooting when the moon is too bright, as it can wash out the Milky Way.

3. Mastering Your Camera Settings
Capturing the night sky requires understanding how to manipulate your camera settings.
3.1. The Exposure Triangle: Balancing Light
Shooting at night is challenging because you need to let in enough light to capture an image while dealing with very dark conditions. The exposure triangle—aperture, shutter speed, and ISO—must work in harmony. The limiting factor is usually shutter speed, as shooting for too long will cause star trails due to the Earth’s rotation.
3.2. Shutter Speed: Capturing Stationary Stars
There is no one-size-fits-all shutter speed; it depends on your camera and lens. Use the PhotoPills Spot Stars Function to determine the correct shutter speed based on your equipment and desired aperture.
For example, with a Sony a7R V and a 24mm lens at f/1.8, PhotoPills may suggest a 7-second exposure. You may find that a range of 6-8 seconds works well.

3.3. Aperture: Letting in Light
If you have a lens with a widest aperture of f/2.8 or f/4, use that. If you have a prime lens with a very wide aperture like f/1.4, shooting at f/1.8 might be preferable.
3.4. ISO: Sensitivity to Light
In very dark locations, you might need to shoot at ISO 6400 or even ISO 10,000 to capture enough light. The trade-off is increased noise or graininess in the image. Noise is more apparent with larger full-frame and high-megapixel sensors.
In locations with ambient light, like near the Church of the Good Shepherd in Tekapo, you might be able to use a lower ISO, such as ISO 2500.

Consider taking multiple shots and stacking them in software like Starry Landscape Stacker or Sequator to reduce noise. You can also take a separate foreground image at a lower ISO and blend it with the sky image in Photoshop. Mastering basic settings is essential before attempting more advanced techniques.
3.5. White Balance: Capturing Natural Colors
While white balance can be adjusted in post-production, setting it correctly in-camera is preferable. A Kelvin White Balance of 4,200 is a good starting point, but adjust it based on the colors you see in the field.
The white balance of the sky can vary significantly, influenced by airglow tones that can make the sky appear pinkish/purple or blue/green. Aim to keep your white balance in your RAW images between 3,600 and 4,200.
4. Achieving Focus in the Dark
Getting sharp focus on the stars can be the most challenging aspect of astrophotography.
4.1. Manual Focus: Taking Control
- Switch your lens to manual focus.
- Use the magnify function on your camera to zoom in on a bright star. The star doesn’t need to be in your final composition, as you can reposition the camera after focusing.
- Adjust the focus ring until the star appears as a pinpoint of light.
- If your camera has focus peaking, use it to help identify when the stars are in sharpest focus.
4.2. Test Shots: Verifying Sharpness
Take a test shot and zoom in on the image to check the stars. If they are round and small, you’re in focus. If they are blurry, adjust the focus accordingly. Elongated stars indicate star trails, so reduce the shutter speed. Minor sharpness issues at the edges are usually due to lens distortion.
