Astrophotography

Definition

Astrophotography is a specialized form of photography that focuses on capturing images of celestial bodies and phenomena in the night sky, such as stars, planets, and galaxies. This practice combines technical skill with knowledge of astronomy to produce stunning images that reveal details invisible to the naked eye, playing a critical role in both scientific research and public engagement with space exploration.
