Guide to Observing DeepSky Objects is a reference book for amateur astronomers. It contains, for each constellation, a star chart showing the Bayer labels, a table for many of the stars in the constellation, along with their positions and magnitudes, and a table of the deepsky objects in the constellation, with relevant observational data. Facing pages provide unique yearlong graphs that show when the constellation is visible in the sky, allowing the user to quickly determine whether a given constellation can be seen, and when the best time to see it will be.
⚠️ WARNING (California Proposition 65):
This product may contain chemicals known to the State of California to cause cancer,
birth defects, or other reproductive harm.
