Report of the Committee on Copper in Drinking Water

Targets are arranged by season to maximise the chances of a given object being visible at the time of observing, and then are divided into four categories: three deep sky categories of increasing difficulty, and then one category of stars that covers things like coloured stars, multiple stars, and loose clusters/streams. The reader can quickly turn to the relevant season, and then work through the list of objects.
Report of the Committee on Copper in Drinking Water of the National Research Council. Reviews the validity of the scientific basis for the EPA's maximum contaminant level goal (MCLG). Discusses the physiological role of copper, health effects of copper deficiencies, disorders of copper homeostasis, and health effects of excess copper. For policymakers and researchers. Softcover.

All existing books about practical deep-sky observing are biased towards non-‘go-to’ telescope owners and usually assume large-aperture instruments and/or dark, rural or desert skies. This book makes the more realistic assumption that the amateur astronomer has a relatively small telescope and is observing from a backyard in a suburban area.

Instead of devoting page after page to maps and co-ordinates, GO-TO Telescopes Under Suburban Skies leaves the computer to locate targets by using NGC and SAO catalog numbers, and so has the space to suggest many more fascinating deep-sky targets and provide detailed observing lists and information about what's being viewed.
