How to shoot stars with iPhone

NightCapPro has a special mode for shooting stars.

Photography method:

Adjust the sensitivity and exposure time. The sensitivity is 3200 or 1600. The exposure time depends on whether you want to shoot star trails or the Milky Way. Star trails will take dozens of minutes. About 30s is enough for Galaxy. In post-processing, you need to adjust contrast, brightness, color temperature, increase sharpness, and reduce noise if there is a lot of noise.

The rise and fall of stars or constellations were often used in ancient times for navigation and determining time. Ancient Egypt determined the beginning of the year by observing Sirius' rising sun; in some areas, the ancient technique of determining orientation through star observation is still preserved. Constellations and the literary images they represent often appear in the works of literati.

Although the importance of constellations has been relatively reduced in modern times, for astronomy enthusiasts, constellations have not lost their charm. Through their fascinating legends, the constellations played an extremely important role in popularizing astronomy. Whenever a significant astronomical phenomenon occurs, astronomers, science popularizers and the media will always set off a craze for astronomy in society, especially among young people.

In the three-dimensional universe, these stars do not necessarily have an actual relationship with each other. However, their positions on the celestial sphere are similar, but in fact they may be very far apart. If humans were in another solar system in the Milky Way, the starry sky they would visit would be completely different. Since ancient times, people have been interested in the arrangement and shape of stars, and they have naturally connected some stars with similar positions to form constellations.
