One of the most famous star atlases of the 20th century, Norton's Star Atlas and Telescopic Handbook 15th Ed. 1969 Celestial Reference HC. This atlas is still in use today by many amateur astronomers including myself. The first half of the book is a reference handbook. The second half is a colored star atlas. The stars go down to 6.5 magnitude. Hundreds of deep sky objects are plotted, including galaxies, star clusters. and nebulae. The Milky Way is colored in light green as it crosses the map. I always take mine out with the telescope! Outstanding condition.This will make a wonderful addition to your library!
