Astro-photography Basics

~60 min · 15 stations

Astro-photography Basics is a self-paced learning path in Astronomy & Space Exploration, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to explain how light interacts with digital sensors to create celestial images; identify necessary equipment for capturing sharp images of the night sky; navigate the night sky to find optimal subjects for photography.
