Night shooting of the starry sky has long been considered the lot of professional photographers with expensive equipment, but modern smartphones, including flagship and mid-budget models Xiaomi, allow you to capture the greatness of space literally from your pocket. Built-in image processing algorithms, large sensors in top models and specialized mode “Night shooting” do wonders, turning dark dots into bright shining objects. You do not need to be an expert in astronomy to get started, but knowledge of the basic principles of how to work a smartphone camera is critical to get a quality result.
The main challenge in shooting stars is the minimum amount of light that must hit the CMOS matrix per unit of time. Xiaomi smartphones solve this problem with a combination of long shutter speed and software stabilization, but this device requires absolute immobility. If you just point the camera at the sky and press a button, you will likely get a blurred image or just a black frame with digital noise. Understanding how your phone controls light in the dark will be the first step to creating a masterpiece.
In this guide, we’ll take a look at everything from location and tripod selection to manually configuring settings in professional mode. You’ll learn why automation often fails when shooting stars and how to use Pro mode or third-party apps to manage ISO and shutter speed. Prepare for the process to require patience and accuracy, but the result in a visible image of the Milky Way is worth it.
Equipment and location preparation required
The first and most important rule of astrophotography on a smartphone is that the device is completely immobile during exposure. Even microscopic hand shaking will lubricate stars, turning them into short tracks or fuzzy spots. So having a quality tripod is not just a recommendation, it's a must. If you don't have a professional tripod, you can use mini tripods with flexible legs or even lean your phone against a stationary object, fixing its position with a load.
The second critical factor is light pollution, and it's almost useless to shoot stars in the middle of a metropolis, because street lights and lights completely clog up the faint light of distant stars, and you have to go out of town, into a zone with minimal artificial light exposure, and use special maps of light pollution to find a suitable place where the sky is really dark and the Milky Way is visible to the naked eye.
⚠️ Warning: Before you start shooting, make sure the camera lens is completely clean. At night, even fat spots or dust can create a "glare" around bright stars that will not be removed during post-processing.
Long exposure, screen operation and real-time processing of photos consume a lot of energy. Cold night weather also affects battery capacity of lithium-ion batteries. It is recommended to fully charge the smartphone before leaving and, if possible, have an external Power Bank battery in case of a long photo shoot.
Use of the built-in mode "Night"
Most modern Xiaomi smartphones, which run on the shell of MIUI or HyperOS, are equipped with intelligent mode “Night”, which automatically takes a series of images with different exposures and combines them into a single frame, suppressing noise and pulling details from the shadows. For beginners, this is the easiest way to get a good result without deep immersion in technical details.
To activate this mode, open the Camera app and select "More" where Night mode often hides, or find the corresponding icon in the bottom menu. After pressing the shutter button, the phone will ask you not to move the device for a few seconds. During this time, the shooting and processing process takes place. HDR (High Dynamic Range) algorithms help to keep detail in both bright areas of stars and in the dark sky.
- 📸 Set your phone on a tripod before starting the mode to avoid lubrication.
- 🌙 Select a Starry Sky scene if it is available in the Shooting Mode Menu.
- ⏱ Do not touch the device until the image processing process is complete.
- 🔦 Turn off the flash and any additional light sources to avoid illuminating the foreground.
Despite its convenience, automatic mode has its limitations: it can misdetermine white balance, making the sky unnaturally orange or too cold; it can also over-sweeten stars by turning them into artificial glowing dots without structure; and it can be more creative and controllable to switch to manual settings.
💡
If the stars still look dim in Night mode, try deliberately underexposing the frame by reducing the EV value to preserve the color of the sky, and then brighten the stars in the editor.
Professional Mode (Pro Mode)
To get really good astrophotos, you need to use a manual mode, often labeled Pro or Professional, where you have full control over exposure parameters, allowing you to tailor the camera to specific lighting conditions. The main parameters you have to adjust are shutter speed, ISO sensitivity and focal length.
Shutter Speed determines how long the matrix will collect light. Stars usually require 10 to 30 seconds to shoot. However, it is worth remembering the “rule of 500”: for the stars in the picture to remain dots, not tracks (due to the rotation of the Earth), the maximum shutter speed in seconds should not exceed 500, divided by the focal length of the lens. For wide-angle cameras of smartphones, this often means a limit of about 20-25 seconds.
ISO sensitivity needs to be selected experimentally. Too low (e.g. 100) will make the frame dark, and too high (3200 and above) will bring digital noise. The optimal range for modern Xiaomi sensors is often between 800 and 1600. White balance (WB) is better set manually in the range of 3500K-4500K, so that the sky looks natural, not blue.
| Parameter | Recommended value | Impact on the photo |
|---|---|---|
| Excerpt (S) | 10s - 30s | It makes stars brighter, but it can cause lubrication from the Earth's rotation. |
| ISO | 800 - 1600 | It increases brightness but increases digital noise (grain). |
| Focus (MF) | Infinity (∞) | It provides clarity to the stars, preventing blurring. |
| White balance (WB) | 3800K - 4500K | It determines the color of the sky (warm or cold). |
It's also important to manually focus. Autofocus in the dark works extremely poorly and can walk. Switch the camera to manual focus (MF) mode and move the slider to the extreme position of Infinity. If the stars are still fuzzy, adjust the slider a little until the image on the screen is as sharp as possible.

The best astrophotography apps on Android
Xiaomi's regular camera app is functional, but sometimes its capabilities are limited by the manufacturer's algorithms.Third-party apps can provide more flexible control over the camera. RAW-One of the most popular solutions is Google Camera (GCam), whose ports often have an excellent Night Sight night shooting algorithm that surpasses stock.
For full manual control, professionals often use the ProCam X or Manual Camera app: RAW. These programs allow you to set the shutter speed longer than 30 seconds (Bulb mode), which is impossible in the standard interface, and save pictures in the format. DNG (RAW). Format RAW Stores all the information from the matrix without compression and processing, which gives huge advantages in subsequent editing on a computer.
- 📱 Google Camera is the best automated processor and HDR+ night-scenes.
- 🎛 ProCam X – Full manual control and format support RAW.
- 🌌 Star Walk 2 is not for shooting, but is indispensable for finding objects in the sky.
- ⚙️ Camera2API — Checking for full manual support with your device.
⚠️ Note: When installing third-party APK-download files such as GCam ports only from trusted sources (e.g. profile forums or developer channels). Unofficial builds may contain malicious code or be unstable.
Use of the RAW-The raw file looks faded and gray, but contains the full potential of the frame. Processing such files in programs like Lightroom or Snapseed allows you to pull out details, remove noise and adjust colors in a way that you can not do with conventional ones. JPEG.
☑️ Checklist before shooting
Shooting technique and composition of the frame
Just taking pictures of stars is only half the story. To make a picture a work of art, you need an interesting composition. An empty black sky with a scattering of dots can look boring. Try to include in the frame the foreground: silhouettes of trees, mountains, buildings or even a human figure, which will add a picture of depth and scale, showing the greatness of space compared to the objects on Earth.
Use the rule of thirds to build a frame. Place the horizon line, or the brightest part of the Milky Way, along the grid lines or at the intersections. Turn on the grid in the settings of the Settings camera → Grid to make it easier to arrange. Experiment with angles: sometimes shooting from the bottom up when the phone is on the ground gives a more dramatic effect.
To capture stellar tracks (when stars turn into long arcs due to the Earth's rotation), you'll need a series of long shutter speed shots taken at intervals, or one very long frame if the app allows. However, for a static shot of the Milky Way, it's important to keep balance: stars should be bright but remain dots. Use a shutter timer (2 or 10 seconds) or voice control so that pressing the descent button doesn't cause the phone to vibrate.
💡
The secret of the composition is that it has an interesting foreground, and without it, the starry sky is flat and incomplete.
Post-processing and noise reduction
The final stage of astrophotography is editing. Even the perfect source needs to be refined. First of all, you need to work with contrast and the black dot. Lower the black level a little bit so the sky gets deep, but don't overdo it so you don't lose the details in the foreground shadows. The Lights and Whites will help make the stars more expressive.
Noise cancellation is the second important step. Nighttime images always have digital noise, especially at high ISO. In applications like Snapseed, use the Details tool for soft noise cancellation. In more advanced editors, you can use brightness masking to remove noise only in dark areas of the sky without touching bright stars.
Color correction also plays a role. Often, automatic white balance is a mistake. Try to shift the temperature to a cooler side to emphasize the depth of space or to a warm one if you want to convey the atmosphere of dawn. You can also selectively increase the saturation of only the blue and purple channels to highlight gas nebulae if they are caught in the frame.
