How to photograph the Milky Way
Few sights in nature are as awe-inspiring as the Milky Way stretching across a dark night sky. From the glowing galactic core and intricate dust lanes to the thousands of stars visible under truly dark conditions, photographing the Milky Way is one of the most rewarding forms of landscape photography. While capturing stunning images of our galaxy may seem technically challenging, modern cameras and lenses make it more accessible than ever. In this guide, you'll learn exactly how to photograph the Milky Way, including the best camera settings, essential equipment, focusing techniques, composition tips, planning tools, and advanced methods such as image stacking and star tracking. Whether you're shooting your first night sky image or looking to improve your astrophotography skills, this step-by-step tutorial will help you create sharper, cleaner and more dramatic Milky Way photographs.
Planning a Milky Way photograph
We need to know where the Milky Way will be in the night sky on the date of our planned shoot – and how its position will change during the night. To do this, the Photopills app is a useful tool. It can show:
1. How visible the Milky Way will be, with consideration to the moon phase.
2. The main hours of visibility for the bright and richly textured Galactic Core.
3. The direction the arch of the Milky Way will take during the night.
4. Whether the Milky Way will appear vertically or horizontally.
The great thing about Photopills is that when we’re on location during the day we can use the app’s augmented reality mode (AR Night) to see where the Milky Way will appear that night, and what path the galaxy will take through the night sky. Why is that important? It means we can scout the landscape in daylight, looking for interesting foreground features, and then return there at night with a good starting point for a strong astro photograph.
What gear do I need to photograph the Milky Way?
You can use your smartphone. The camera sensors in the latest models produce surprisingly good results (in night mode), but the quality is still far below digital cameras.
• Full-frame DSLR or mirrorless camera body
With their bigger sensors, full-frame cameras collect more light and you can capture more detail in the night sky at a higher ISO with less noise compared to cropped-sensor cameras.
• Wide-angle lens with fast aperture
Focal lengths between 14mm and 24mm are ideal for most Milky Way photography, allowing you to capture large sections of the galactic core and arch while maintaining strong foreground interest. Wider lenses can be useful for panoramic compositions, while focal lengths around 20-35mm often produce stronger, more dramatic views of the galactic core.
• Tripod
A sturdy tripod is essential for the long exposures required in astrophotography. Ideally, use a geared head for fine adjustments when setting up your night shoot.
• Remote Release
Although the camera’s 2s self-timer can be used for most situations, a remote release simplifies things.
• Headtorch
Always choose one with a red light setting so your night vision is not affected.
• Spare Batteries
Long exposure photography drains batteries quickly, so be sure to have one or two spares.
• Star-Tracker
Although not essential, a star tracker allows you take longer exposures than a single shot of the Milky Way, and capture sharper, more detailed images. How does it do this? A star tracker counters the Earth’s rotation by pivoting your camera at the same speed as the stars move across the sky. This prevents ‘star trails’, and allows you to capture exposures lasting for minutes rather than seconds.
What compositions are best for Milky Way photographs?
Simply pointing your camera at the sky and shooting the Milky Way is fine for starters, but providing foreground interest makes a more dramatic composition, and also adds scale and context. The Milky Way can be orientated as an arch over the horizon – perfect for a wide-angle panorama which frames trees, mountains, rock arches etc. Sometimes, the galaxy can appear as a diagonal band, which can be used to lead your eye to a single key feature like a charismatic tree or rock formation.
What if I can’t fit the whole The Milky Way into my frame? Well, things get more complex! The best option is to shoot a vertical panorama, stitching together multiple frames.
What if the moon is out? The Milky Way might appear less bright and detailed, but the moon can softly illuminate the landscape, adding depth and interest to a night-time landscape.
What settings should I use for photographing the Milky Way?
• ISO: Cameras handle noise differently. Modern full-frame cameras can often produce usable images at ISO 12800 and beyond, but for most situations a good starting point is ISO 3200-6400. Noise is generally easier to deal with than star trails or underexposure.
• Aperture: Use the widest possible aperture, unless you’re using a very fast lens (like f/1.4 or f/1.8) in which case consider stopping down slightly to avoid stars at the edges of your frame appearing distorted with blurred, ‘comet-like’ tails, rather than sharp pinpoints of light (an optical distortion known as ‘coma’).
• Shutter Speed: We want the stars to appear as sharp bright points of light. But because of the earth’s rotation, a long exposure of 20-30 seconds or more will cause them to be rendered as short star trails. In the past, the 500 Rule (500 divided by the lens focal length equals the maximum exposure time to capture stars as points, rather than trails) was a reliable guide – but it’s not as accurate with modern sensors. Instead, use the NPF Rule. It’s a complex formula, but fortunately the Photopills app does the work for you. Just type in your camera model, focal length and aperture into the app, and you’ll see the best shutter speed for taking pictures of the Milky Way using your particular set-up.
• Other settings
– Shoot in RAW to capture as much detail and exposure information as possible.
– Set white balance between 3900K and 4500K for a cool, blue tone to the night sky while allowing the orange and yellow dust lanes of the galactic core to pop naturally. You can always tweak this later in editing.
– Use Manual shooting mode and manual focus.
– Turn down your LCD screen brightness. It’s easy to underexpose your Milky Way images by relying on the LCD screen. Instead, use your histogram (more on that later).
Step-by-step guide to photographing the Milky Way
Technique 1: A single-shot approach for beginners
01.
Recce the location during the day and use the Photopills Augmented Reality mode to work out a promising composition (and shooting period) for later.
02.
Artificial light pollution is rarely an issue in Namibia, but it goes without saying that you want to seek out dark night skies. Cloud cover can also affect your Milky Way photography.
03.
Set up your camera as follows: Manual mode • Manual focus • RAW • ISO 6400 as a starting point • f/2.8 (or wider) • Shutter speed determined by the NPF rule calculated using Photopills • White balance between 3900K and 4500K • Evaluative or matrix metering • Remote release attached, or 2s self-timer selected • LCD Brightness low
04.
Make sure you have the following: head torch with red light setting, tripod, spare batteries and warm clothes, plus star tracker if you’re using one.
05.
Recce the location during the day and use the Photopills Augmented Reality mode to work out a promising composition (and shooting period) for later.
06.
Set up your tripod and camera. Hang your camera bag under your tripod for extra stability,
07.
Set the focus using the following steps:
– Make sure your lens focus mode is switched to manual.
– Turn on Live View mode on your camera to activate the LCD screen.
– Point your camera at a bright star.
08.
Using the magnifying button on your camera (usually denoted by a magnifying glass symbol), magnify the view by x5 or x10 and then adjust the focus ring of your lens manually until the star comes into sharp focus (the smallest, brightest spot of light).
09.
Take your first test shot. Rather than judging the exposure solely on what you can see on your camera’s LCD, check the histogram. Generally, the histogram should sit clear of the left edge and be positioned around the left third of the graph. A night sky image should not look like a daylight exposure, but avoid clipping shadows completely against the left edge.
10.
Remember: you’re shooting in RAW, so there is lots of potential to tease out more of that glorious Milky Way in post-processing. Don’t expect dazzling ‘astro perfection’ straight out of the camera! To adjust exposure settings, start by tweaking the ISO, but keep in mind the noise tolerance of your camera

Technique 2: How to reduce noise and get both the stars and the foreground sharp
Single-shot Milky Way photography is an excellent way to get started, but professional-quality nightscape images are usually created from multiple exposures. The challenge is that the stars and the foreground often require different settings and different focus points:
​
• Stars require precise focus at infinity.
• Foregrounds often require focusing much closer.
• A noisy sky benefits from stacking multiple exposures.
• A foreground may benefit from a lower ISO and longer exposure.
The solution is to photograph the sky and foreground separately.
01.
Capture a Stacked Sky
​
1. Set up your composition and focus precisely on the stars.
2. Use the same settings determined using the NPF rule.
3. Capture between 5 and 20 identical sky exposures.
4. Do not change focus, composition or camera position.
5. Use an interval timer or remote release to automate capture.
Stacking multiple exposures dramatically reduces noise and reveals faint detail in the Milky Way.
02.
Capture a Dedicated Foreground Exposure
Once your sky exposures are complete:
1. Refocus carefully on the foreground.
2. Lower the ISO if desired.
3. Use a longer exposure if conditions permit.
4. Capture one or more dedicated foreground frames.
Typical foreground settings might be: ISO 400-1600, f/4-f/8, 30 seconds to several minutes
depending on the scene.
03.
Optional Blue-Hour Foreground
Many professional nightscape photographers photograph the foreground during blue hour or twilight and blend it with the night sky later. Advantages include lower noise, better colour, easier focusing and greater foreground detail.
04.
Blend During Post-Processing
The final image may consist of:
• stacked sky
• dedicated foreground exposure
• optional blue-hour foreground
These elements are blended together in Photoshop.
How do I process my Milky Way photographs?
Before you start processing your Milky Way images, decide on the kind of effect you’re after. Some photographers go for very bright, high-contrast editing with the Milky Way on steroids and the landscape bathed in surreal starlight. Others prefer a more muted ‘natural’ look. Do you prefer a cooler ‘blue’ look to the night sky, or something slightly warmer?
You’ll need editing software such as Adobe Lightroom or Photoshop. There are two common approaches:
​
1. Single-shot workflow
2. Stacked sky and blended foreground workflow
Workflow 1: Processing a Single-Shot Milky Way Image
RAW Preparation
Before making creative edits:
• Enable Lens Corrections
• Remove Chromatic Aberration
• Crop and straighten if required
1
Build Contrast
A useful starting point:
• Highlights slightly down
• Whites slightly up
• Blacks slightly down
• Shadows adjusted carefully
This usually preserves star colour better than simply increasing overall contrast.
4
Refine Colour
Use Vibrance before Saturation. Be particularly careful with blues, magentas and orange galactic dust lanes. Natural-looking colour usually produces more convincing results.
​
Colour Grading
A subtle starting point which can add depth while maintaining realism:
• slightly cooler shadows
• slightly warmer highlights
​
​
​
​
​
​
7
Adjust White Balance
A good starting point is 3900K-4500K. Fine-tune according to the scene and your preferred style
​
2
Remove Light Pollution and Gradients
In order to reduce any horizon glow, colour casts or uneven sky brightness, use:
• Linear Gradient masks
• Curves adjustments
• Local colour corrections
​
5
Noise Reduction and Sharpening
Masking is particularly important to prevent sharpening noise in smooth sky areas. Good starting values:
Noise Reduction
• Colour NR: 15-25
• Luminance NR: 10-30
Sharpening
• Amount: 20-40
• Radius: 0.5-0.8
• Detail: 20-60
• Masking: 70-90
8
Establish Overall Exposure
Increase exposure carefully. Remember, it is still a night photograph. Avoid making the sky look like daytime.​​
3
Enhance Galactic Structure
Avoid excessive use of these controls, as they can create halos and exaggerate noise.
• Texture +5 to +20
• Clarity +5 to +15
• Dehaze +5 to +20
​
6
Local Adjustments
Milky Way Enhancement
Apply a radial mask over the galactic core and slightly increase contrast, increase texture and subtly brighten dust lanes
Dodge and Burn
Use a soft brush to enhance dust lanes and gas clouds
​
Foreground Adjustments
Use masks to refine white balance, exposure, noise reduction
and colour balance

​
Workflow 2: Processing a Stacked Sky and Blended Foreground
Stack the Sky
Export the sky exposures as 16-bit TIFF files and stack them using software such as Starry Landscape Stacker.
​​​
​
​
​
​
​
​
1
Process the Stacked Sky in Lightroom
Apply the same workflow described above. Because stacking has already reduced noise:
• use less noise reduction
• sharpen more gently
• focus on contrast and colour
4
If using Starry Landscape Stacker:
• Export your sky images from Lightroom as 16-bit TIFFs with no sharpening or noise reduction.
• Open Starry Landscape Stacker and select all sky exposures.
• Choose the sharpest image as the reference frame.
• Allow the software to align the stars automatically.
​
​
2
Process the Foreground Separately
The foreground often requires:
• different white balance
• different noise reduction
• different exposure adjustments
Edit it independently from the sky.
.​​
5
Next steps with Starry Landscape Stacker:
• Review the automatically generated sky and foreground mask.
• Refine the mask manually if required (green = sky, red = foreground)
• Click ‘Align and Save’. The software will align stars, average noise, preserve foreground detail and generate a stacked image
• Save the result as a 16-bit TIFF and return to Lightroom for editing.
3
Blend in Photoshop
a) Open both files as layers.
b) Place the sky layer above the foreground layer.
c) Auto-align if necessary.
d) Add a layer mask.
e) Carefully blend the sky and landscape together.
6
Using a star tracker
In recent years, entry-level and ultralight equatorial mounts have made possible something that was unthinkable a few years ago: Tracking the Miky Way with basic camera gear.
Using an equatorial wedge and a simple motor, we can track the Milky Way, which allows us to use narrower apertures, lower ISOs, and a longer shutter speed, which will translate into sharper and more quality images.
Using a star-tracker involves a few more technical things to consider, like doing a correct polar alignment so the star-tracking works, or blending the images in post-processing since the ground area will be blurred. However, if you have some experience and are comfortable shooting the Milky Way with your current gear, using a star-tracker is the best tool to take your Milky Way shots one step further.
Because the tracker follows the movement of the stars, the landscape will appear blurred during a tracked exposure. For this reason, astrophotographers typically capture separate tracked sky exposures and separate untracked foreground exposures, blending them together during post-processing. This reflects modern tracked Milky Way workflows used by most advanced nightscape photographers.
