Uses of astronomy laser pointers
Astronomical observation
Astronomy laser pointers are widely used in astronomical observations. Green laser pointers are convenient for observing the starry sky at night because of their bright beams and strong resistance to stray light interference. The light emitted by the green laser forms a bright beam in the night sky, which can help astronomy enthusiasts accurately point out the position of stars, making observation more convenient and accurate.
Star Pointing
The green laser pointer is often called a "star pointer" because of its visible strong beam and long-distance pointing capability. Astronomy laser pointers can help users point to distant celestial targets, especially on moonless nights.
