The night sky atlas creates images of any part of the night sky, allowing easy location of any object.
Detailed chart images show all stars visible to the naked eye, the constellations, Messier objects, and names of the brightest stars.
Data sources: Bright Star Catalog from the Astronomical Data Center,
star names list from Steven Gibson,
all-sky Milky Way image by Axel Mellinger.
