Based on field notes made by the author during his own career as an amateur astronomer, this unique guide covers both the traditional and novel approaches to studying the night sky. In addition to the more standard techniques, it discusses the latest modern resources available to today's astronomer, such as personal computers, the Internet, and computerized telescopes. It includes practical advice on aspects such as site selection and weather; provides the reader with detailed instructions for observing the Sun, Moon, planets, and all types of deep-sky objects; and it introduces newer specialities such as satellite observing and the use of astronomical databases. The book concludes with detailed information about 200 stars, clusters, nebulae, and galaxies, suitable for viewing with modest-sized telescopes under suburban conditions. Written to complement How to Use a Computerized Telescope, this book will also appeal to astronomers with more traditional equipment.

Listing more than 500 sky targets, both near and far, in 187 challenges, this observing guide will test novice astronomers and advanced veterans alike. Its unique mix of Solar System and deep-sky targets will have observers hunting for the Apollo lunar landing sites, searching for satellites orbiting the outermost planets, and exploring hundreds of star clusters, nebulae, distant galaxies, and quasars. Each target object is accompanied by a rating indicating how difficult the object is to find, an in-depth visual description, an illustration showing how the object realistically looks, and a detailed finder chart to help you find each challenge quickly and effectively. The guide introduces objects often overlooked in other observing guides and features targets visible in a variety of conditions, from the inner city to the dark countryside. Challenges are provided for the naked eye, through binoculars and the largest backyard telescopes.

The volume forms a part of the celebrations marking the anniversary of the invention of the telescope. From its Renaissance beginnings to yesterday’s Cold War, the essays contributed here throw a spotlight on a number of significant episodes in the continuing adventures of this well-loved instrument, which has played a crucial role in Man’s thinking about his position – literally and philosophically – in the universe. Drawn from various conferences held by the Scientific Instrument Commission of the International Union of the History and Philosophy of Science between 2007 and 2009, these papers make a substantial contribution to our current knowledge about this fascinating optical instrument.

Between 1608 and 1610 the canopy of the night sky was ripped open by an object created almost by accident: a cylinder with lenses at both ends. Galileo’s Telescope tells how this ingenious device evolved into a precision instrument that would transcend the limits of human vision and transform humanity’s view of its place in the cosmos.

Challenging monolithic modern narratives about 'Chinese science', Daniel Patrick Morgan examines the astral sciences in China c.221 BCE-750 CE as a study in the disunities of scientific cultures and the narratives by which ancients and moderns alike have fought to instil them with a sense of unity. The book focuses on four unifying 'legends' recounted by contemporary subjects: the first two, redolent of antiquity, are the 'observing of signs' and 'granting of seasons' by ancient sage kings; and the other two, redolent of modernity, involve the pursuit of 'accuracy' and historical 'accumulation' to this end. Juxtaposing legend with the messy realities of practice, Morgan reveals how such narratives were told, imagined, and re-imagined in response to evolving tensions. He argues that, whether or not 'empiricism' and 'progress' are real, we must consider the real effects of such narratives as believed in and acted upon in the history of astronomy in China.

This book provides a unified treatment of the characteristics of telescopes of all types, both those whose performance is set by geometrical aberrations and the effect of the atmosphere, and those diffraction-limited telescopes designed for observations from above the atmosphere. The emphasis throughout is on basic principles, such as Fermat's principle, and their application to optical systems specifically designed to image distant celestial sources.The book also contains thorough discussions of the principles underlying all spectroscopic instrumentation, with special emphasis on grating
