Astronomy Laser Pointer Pen
This astronomy grade “gred†laser pointer offers you both the advantages of a green and red laser pointer. The green laser beam itself is visible through Rayleigh scattering and airborne dust. With a 50mW output, this green laser pointer beam can be clearly seen on a moonless night, allowing you to accurately point out individual stars to your friends nearby on a camping trip. Also, these green laser pointers can be used by astronomers at star parties or for conducting lectures in astronomy. Red laser pointers can be used in almost any indoor or low-light situation where pointing out details by hand may be inconvenient.
