How to shoot the starry sky with iphone

NightCapPro has a special mode of shooting starry sky.

Shooting method:

Adjust the sensitivity and exposure time. Sensitivity is 3200 or 1600. The exposure time depends on whether the individual wants to shoot the star orbit or the Milky Way. For the star orbit, it takes tens of minutes, and the Milky Way is about 30s. Later, we need to adjust the contrast, brightness and color temperature to increase sharpness. If there is too much noise, we should reduce it.

In ancient times, the rise and fall of stars or constellations were often used to navigate and determine time. Ancient Egypt determined the beginning of a year by observing the rise of Sirius. In some areas, the ancient technology of determining position by observing stars still remains. 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, they have not lost their charm for astronomy lovers. Through its fascinating legend, constellations have played an extremely important role in the popularization of astronomy. Whenever there is a major astronomical phenomenon, astronomers, popular science workers and the media will always set off an astronomical upsurge in society, especially among young people.

In the three-dimensional universe, there is no necessary connection between these stars. Their positions on the celestial sphere are similar, but in fact they may be far apart. If humans were in another solar system of the Milky Way, they would see the starry sky completely differently. Since ancient times, people have been interested in the arrangement and shape of stars, and naturally linked some stars with similar positions to form constellations.
