How to photograph the orbit of a star

The key to shooting the orbit of a star is a long exposure time. In order to get a good star-orbiting work, I personally feel that the following conditions are indispensable:

1. Clear environment and high visibility at night; It is best to take photos in suburbs or high altitude areas, where the visibility of the sky is better at night.

2. A reliable and stable tripod; The most important equipment for shooting star orbits is a tripod. Portable tripods are generally difficult to ensure long-term stability. It is suggested to choose a heavier tripod and add a counterweight or reinforcement under it.

3. SLR supports B shutter+wired release with quick door lock; It takes a long exposure to photograph the orbit of a star. For a photographer, it is definitely not possible to hold the shutter with your hands for a long time. Therefore, cable release with quick lock is necessary.

4. Try to use a wide-angle lens; Generally speaking, works around the stars will use wide-angle lenses to show the panoramic effect of the starry sky as much as possible. Of course, trying different lenses (such as fisheye lenses) may have unexpected effects.

5. battery; Usually, the low temperature at night will affect the service time of the camera lithium battery. Especially in winter, the performance of lithium batteries will be seriously degraded. Therefore, remember to use a fully charged battery or install a battery box when preparing to shoot long-exposure star-orbit works.

The above is my original summary, and other friends are welcome to add it.
