Amateur astronomers of all expertise from beginner to experienced will find this a thorough
star cluster atlas perfect for easy use at the telescope or through binoculars. It enables
practical observers to locate the approximate positions of objects in the sky organized by
constellation. This book was specifically designed as an atlas and written for easy use in
field conditions. The maps are in black-and-white so that they can be read by the light of a
red LED observer's reading light. The clusters and their names numbers are printed in bold
black against a grayed-out background of stars and constellation figures. To be used as a
self-contained reference the book provides the reader with detailed and up-to-date coverage of
objects visible with small- medium- and large-aperture telescopes and is equally useful for
simple and computer-controlled telescopes. In practice GO-TO telescopes can usually locate
clusters accurately enough to be seen in a low-magnification eyepiece but this of course first
requires that the observer knows what is visible in the sky at a given time and from a given
location so as to input a locatable object. This is where The Observer's Guide to Star
Clusters steps in as an essential aid to finding star clusters to observe and an essential
piece of equipment for all amateur astronomers.
