An astrophotographer is a photographer who specializes in capturing images of celestial objects and phenomena. This includes stars, planets, galaxies, and other elements of the night sky. They often use telescopes and specialized cameras to obtain detailed images, sometimes requiring long exposure times to gather enough light from distant objects. Astrophotography combines art and science, as it requires knowledge of both photography techniques and astronomy. Many astrophotographers share their work online, contributing to communities focused on space exploration and education. They may also participate in events like the International Dark-Sky Association to promote awareness of light pollution and its effects on stargazing.
