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.    A major feature is an included CD-ROM containing a PC program [unique as far as we can determine] that produces a list of what deep-sky objects are visible in the sky at a user-determined time and place, for any location on the Earth. It produces a convenient and (disposable!) list that the user can take to the telescope for an observing session.
