The moon is one of the most mysterious and photogenic objects in the sky, but taking a picture of it on a smartphone in a way that is clear and detailed is not possible for everyone. Owners of the Xiaomi Redmi Note 9 often face blurred frames, over-lit areas or a complete lack of detail on the surface of the satellite. The problem is not the camera — just need to know a few tricks that will turn your smartphone into an astrophotography tool.
In this article, we'll learn how to set up Pro mode in a standard camera app, what accessories will help improve the result, and how to process the image after shooting. You'll learn why autofocus on the moon works worse than on Earth objects, and how to get around this limitation. And also what mistakes spoil 90% of amateur photos of the moon and how to avoid them.
Why the Moon is a Bad Photo: The Biggest Mistakes
Even with modern smartphones like the Redmi Note 9 (which has a 48MP main camera), many users are getting disappointing results.
- 🌕 Automotive is not suitable for astrophotography. In normal mode, the camera tries to brighten the dark sky, which causes the moon to turn into a white spot with no details.
- 📱 Hand shaking. Even microscopic movements that are long exposure blur the image. There's no optical stabilization on the Redmi Note 9, so the problem gets worse.
- ⚙️ Wrong settings ISO And the exposure. ISO adds noise, and short shutter speeds do not allow you to collect enough light.
Another common mistake is trying to make zoom digitally, where digital zoom just stretches the pixels, making the image grainy, instead, you'd better take a picture of the moon without zoom, and then crop the frame in the editor.
⚠️ Note: Do not use the built-in flash - it is absolutely useless when shooting the moon and will only worsen the quality of the picture by creating glare on the lens.
Preparation of the smartphone: camera settings before shooting
To get the clearest picture possible, you need to put the Redmi Note 9 camera in Pro mode (aka “Professional” or “Manual”), which allows you to manually control key parameters:
- 🔘 Focus - set the value in ∞ (Infinity or use manual focusing.
- ⏱️ Exposure - optimal from 1/100 before 1/200 Seconds (depending on lighting).
- 📷 ISO — No more than 400-800, otherwise there will be noise.
- 🔄 White balance – choose Daylight (nearly) 5500K).
It's important to turn off HDR and AI-Improvement: these features are for daytime images and will only distort the image of the moon. JPEG (not HEIF), to avoid editing problems.
| Parameter | Recommended value | Why is it important? |
|---|---|---|
| Focus | ∞ (infinity) | The moon is too far away for autofocus, manual tuning gives clarity. |
| Excerpt. | 1/125–1/250 with | Too long exposure will erod the moon because of the Earth's motion. |
| ISO | 200–600 | High ISO adds noise, low ISO makes the image dark. |
| White balance | Daylight | Automatic balance can make the moon yellow or blue. |
Quality Improvement: What Really Helps
Even with the right camera settings, the Redmi Note 9 has physical limitations: a small matrix and no optical zoom. Fortunately, there are inexpensive accessories that solve these problems:
- 🔭 Telephoto lens for smartphone (for example, Xiaomi Lens) 2x Optical Zoom. Scaling up without loss of quality.
- 📸 A tripod or a monopod, it eliminates the trembling of the hands during prolonged exposure, even a mini-station with flexible legs will do.
- 🔄 Remote descent (or headphones with volume button) allows you to take a picture without touching the screen.
- 🌌 Light filter (optional) helps reduce the impact of city light.
If you don't have a telephoto lens, you can use afocal photography method: point your smartphone camera at the eyepiece of your binoculars or the spying tube, and the key is to lock your smartphone to avoid bias.
💡
Before shooting, clean the camera lens of dust and fingerprints – even small contamination can create glare in the photo of the moon.
How to take a picture of the moon on Redmi Note 9
Follow this algorithm to get the most accurate picture possible:
- Place your smartphone on a tripod or put it on a stable surface, and if you don't have a tripod, put your hands against a wall or a table.
- Open the Camera app and go to Pro mode (fly through modes to the left).
- Configure the settings: Focus: ∞ (or manually focus on the moon). Shutter speed: 1/125. ISO: 400. White balance: Daylight.
Use a timer or remote

☑️ Checklist before shooting
If the moon is too dark, increase the ISO slightly (to 800), but not higher, otherwise there will be noise. If it is overlit, reduce the shutter speed to 1/500.
⚠️ Warning: Don't use digital zoom in the camera app - it only degrades quality. Better take a picture of the moon at maximum resolution (48 MP if available) and then crop the frame in the editor.
Photo processing: how to make the moon even better
Even the perfect shot can be improved with simple tools.
- ✂️ Cut out the extra sky, leaving only the moon, and that will increase the detail when you look at it.
- 🔧 Exposure correction. In Google Photos or Snapseed, reduce the brightness slightly and increase the contrast.
- 🎨 Use the Sharpening tool (but don't overdo it, or you'll see artifacts).
- 🌑 Noise removal. ISO Denise filter will help in Lightroom Mobile.
If the moon is too yellow or blue, adjust the white balance in the editor. For a realistic color of the moon's surface, the temperature should be about 5,000–5500K.

Common myths about shooting the moon on a smartphone
There are a lot of tips on the Internet that not only don't help, but also spoil the pictures.
- 📴 «You have to take pictures on the full moon. In fact, on the full moon, the moon is too bright and you can't see craters. You'd better choose the phases when the moon is illuminated at an angle (first/last quarter).
- 🌆 «Urban light doesn't affect quality. Even if the moon is clearly visible, artificial light adds noise and reduces contrast.
- 🔋 «You need to fully charge the battery. Battery charge does not affect the quality of the photo, but at low charge, the smartphone can turn off during shooting.
Another myth is that you need a flagship smartphone to shoot the moon, and in fact, the Redmi Note 9, with the right settings, can do as well as many more expensive models, thanks to its 48-megapixel sensor.
💡
The most important thing when shooting the moon is manual settings (infinity focus, short shutter speed) and smartphone stabilization. The hardware is secondary.
