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. The data used in this product, in whole or in part, is used with permission of The NGC/IC Project LLC. Many thanks go to those who maintain and make available their astronomy datasets without which this sky atlas would not have been possible. Permission for any use of these chart images is granted, provided that the original website address remains visible on all images. Enjoy!
