This title is a comprehensive set of visual descriptions of deep-sky objects visible from the northern hemisphere. It is a record of the most extensive and systematic visual survey of the sky ever done in modern times. 3,000 deep-sky objects are listed with short descriptions of the visual appearance in the author's powerful binocular telescope. Objects in the book are organized by position for easy identification of unknown targets. Full indexes by catalog numbers and names allow searches for specific objects.

Enables quick and easy location and identification of 3,000 deep-sky objects Descriptions make for easier practical object recognition than photographs Written as the result of a four-year observing project, this is the best source for realistic, accurate, no-nonsense descriptions of deep-sky objects

Ted Aranda earned his Master degree in history at the University of Chicago. From 1997 to 2008, he worked on obtaining a PhD at the University of Illinois-Chicago. Ted is a member of the Chicago Astronomical Society and has been an avid amateur astronomer and telescope maker for 25 years. He started observing the sky in 1986 from northern California using small binoculars and an 80mm telescope. In 1996, after having moved to Chicago, he designed and built a 10-inch Cassegrain binocular telescope, and used this along with two ancillary binoculars, to survey the sky more thoroughly.

Klappentext
The Annotated Catalog of 3,000 Deep-Sky Objects is a record of the most extensive and systematic visual survey of the sky done in modern times. The 3,000 deep-sky objects listed contain short descriptions of what these objects look like in the author's powerful binocular telescope. Objects in the book are organized by position for easy identification of unknown targets. Full indexes by catalog numbers and names allow searches for specific objects. Descriptions of objects are better than photographs for identifying deep-sky objects because the visual appearance never matches the photographic image. Nor are sketches entirely satisfactory because there is a strong unconscious tendency to draw what the observer remembers from photographs of objects. Compared to other astronomical guidebooks this book contains by far the largest number of objects viewed through a 10- to 14-inch telescope and is a 'must-have' for serious amateur and professional observers.
