Guide to Observing Deep-Sky Objects : A Complete Global Resource for Astronomers

Guide to Observing Deep-Sky 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 deep-sky objects in the constellation, with relevant observational data.

Facing pages provide unique year-long 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.
