Observing Handbook and Catalogue of Deep-Sky Objects
註釋A detailed and comprehensive guide to observing the deep sky, this is the most detailed guide available in a single volume. Information and descriptions for more than 2000 galaxies, nebulae and star clusters was meticulously researched and checked for this book, removing the common transcription errors in other catalogues. The objects range from those visible in binoculars to faint galaxies requiring a 30 cm telescope, and most descriptions are given for a range of telescope apertures. An essential reference for telescope users.
