How does Canon m3 shoot the starry sky?

The first step is to find a place with a good prospect, but it must be a suburb (you can go online to see the recommended location for shooting the starry sky nearby) and confirm the weather in the next few days. No rain, no fog, no cloudy, no bright moon.

Step 2, prepare a tripod or other accessories that can replace the bracket and adjust the angle.

When shooting, you should expose it for a long time. If it is M3, you can choose ISO800- 1600, aperture F4 or F5.6, and the exposure time is about 20S. Just try a few more when choosing the prospect.

I wish you a good photo!
