Astronomy lasers are powerful tools used by star enthusiasts and amateur astronomers to point out celestial bodies in the night sky. These lasers are often green for optimal visibility and may feature adjustable focus for precision pointing. They help in identifying constellations, planets, and stars during night sky observations. Made with rugged materials suitable for outdoor use, these pointers often include features like water resistance and extra-long battery life. Astronomy lasers are invaluable for educational purposes and for enhancing the stargazing experience, making them popular in planetariums and astronomy clubs.
