Excerpt from The Astronomical Observer: A Handbook to the Observatory and the Common Telescope "Mysterious Night! when our first parent knew Thee from report divine, and heard thy name, Did he not tremble for this lovely frame, This glorious canopy of light and blue? Yet, 'neath a curtain of translucent dew, Bathed in the rays of the great setting flame, Hesperus with the host of heaven came, And, lo! Creation widen'd in man's view. Who could have thought such darkness lay conceal'd Within thy beams, O Sun! or who could find, Whilst fly, and leaf, and insect stood reveal'd, That to such countless orbs Thou mad'st us blind! Why do we then shun death with anxious strife? If light can thus deceive, why may not life?" The history of Astronomical Science is probably coeval with the history of man. The unrivalled splendour of the night sky would naturally awaken interest, that interest would induce observation, and observation would soon inculcate the leading principles of astronomy. If Adam wept, as poets tell us, when he beheld the first sunset, his sorrow must have been very soon turned into joy at the appearance of Sirius, "monarch of the suns," with his heavenly host. Josephus asserts that "God indulged the antediluvians with a very long life, in order that they might bring astronomy and geometry to perfection;" and that "Abraham was a most intense observer of the stars, and the first to bring astronomy from Chaldea into Egypt." Job certainly possessed an intimate knowledge of the heavens, for this is implied in the questions addressed to him by the Creator, "Canst thou bind the sweet influences of Pleiades, or loose the bands of Orion? Canst thou bring forth Mazzaroth in his season? or canst thou guide Arcturus with his sons? Knowest thou the ordinances of heaven? canst thou set the dominion thereof in the earth?" - Job xxxviii. 31 - 33. David was an observer of the heavens, and composed some astronomical hymns (Psa. viii. and xix.) for the services of the Temple; Isaiah exhorted the Hebrews to a contemplation of the starry firmament as a ground of confidence in God: "Lift up your eyes on high, and behold who hath created these things, that bringeth out their host by number.

One of the wonders of the universe we live in is the Milky Way. It spans the entire sky and can be seen every night of the year from anywhere on Earth. This is the first book that deals specifically with what can be seen within the Milky Way from a practical observer's point of view. Astronomy of the Milky Way covers every constellation that the Milky Way passes through, and describes in detail the many objects that can be found therein, including stars, double and multiple stars, emission nebulae, planetary nebulae, dark nebulae and supernovae remnants, open and galactic clusters, and galaxies. It also describes the one thing that is often left out of observing guides - the amazing star clouds of the Milky Way itself. It is one of a two-volume set that deal with the entire Milky Way - this second volume looks at what can be seen predominantly from the Southern skies In addition to the descriptive text there are many star charts and maps, as well as the latest up-to-date images made by observatories around the world and in space, as well as images taken by amateur astronomers. Equipped with this book, an amateur astronomer can go out on any clear night of the year and observe the galaxy we live in - The Milky Way.

This book contains everything you need to know about variable stars -- stars whose brightness varies noticeably over time. The study of variable stars has been a particularly popular area of research for amateurs for many years; the material contained herein serves as both an introduction to amateur astronomers and a useful reference source for seasoned variable star observers. With its thorough, non-mathematical descriptions of variable stars and tips for how to see them, this book enables novices and experts alike to set off into the field and observe a wide range of delightful sights. It strikes a balance between easily visible objects that can be seen in any telescope or binoculars, and variable stars that are a direct challenge to those with large aperture equipment or access to photometric tools and methods. After helping the observer differentiate between variable star types, the author goes on to explain the skills needed to operate a telescope and other equipment, as well as how to couple filters to a CCD camera or digital SLR camera in order to photometrically record these celestial objects. Further, the book includes an observational guide to 50 objects for study, with finder charts and data about light curves for ease of identification, along with the stars’ celestial coordinates, magnitudes, and other pertinent information.

The Casual Sky Observer's Pocket Guide offers an observing program for occasional amateur observers looking for some quick, fun astronomy adventures under the stars. In the real world, where time for observing is limited, the weather is seldom perfect, and expensive equipment is not an option, amateur astronomy may not be seen as a worthwhile activity. However, portable and quick-to-set-up instruments are available. A pair of binoculars or a small telescope fills the bill. And the way to make the most of these instruments is described in the Casual Sky Observer's Pocket Guide. Not only does the book feature the best and brightest showpieces of the heavens; it also provides a great deal of physical and environmental data as well as lots of fascinating information and beautiful illustrations that provide a unique perspective on the many treasures within and beyond our home galaxy, the Milky Way--stars, star clusters, other galaxies, and nebulae, all within reach of binoculars or a small telescope.

The treatise by Jeremiah Horrocks (1618-1641) on the transit of Venus of 1639 is an account of an important astronomical observation, as well as an analysis and commentary on the changing state and practice of astronomy during the significant period between the achievements of Johannes Kepler (1571-1630), Galileo Galilei (1564-1642) and Isaac Newton (1642-1727). This work has, in addition, the power to delight and charm us as the record of a young astronomer’s encounter with a rare astronomical event and the manner in which he discovered, observed, and drew conclusions from it. Its appeal is heightened by the knowledge that a self-trained young man stole a march on all the astronomers of his day.

This guide provides comprehensive practical information for both beginning and advanced amateur astronomers on how to make scientifically significant observations. The book explains in detail how to observe every conceivable astronomical object--from meteors to distant galaxies. It presents a wide variety of methods ranging from the simplest visual observations, such as making pencil drawings of the surface of the Moon, to the use of highly sophisticated equipment, such as CCD cameras and photoelectric photometers. It also explains how to record and catalog observations using recognized professional terminology and classification schemes. The volume's emphasis throughout is on giving amateur astronomers sound information to use at the telescope. The most effective and efficient techniques are presented so that observers can apply those that are most suitable to their own equipment and degree of experience. This comprehensive survey of practical methods of observation will develop the observational skills of the avid novice and will also satisfy the more demanding needs of the experienced amateur astronomer.

"Twenty-Five Astronomical Observations That Changed the World" takes twenty-five journeys through space, back in time and into human history. We begin with the simplest sight of the Tycho Crater on the Moon, through a repeat of Galileo's observations of Jupiter's moons, and then move out towards the nebulae, stars, and galaxies. The astronomical observations repeat the original groundbreaking discoveries that have changed our understanding of science and ourselves. This title contains graded observing challenges from the straightforward to the more difficult (in chapter order). It offers clear observing tips and lots of practical help, presuming no prior in-depth knowledge of equipment. Binoculars and/or a small astronomical telescope are all that is required for most of the observations. Secondly, it explores for each observation the science of what is seen, adding to the knowledge and enjoyment of amateur astronomers and offering lots of reading for the cloudy nights when there is not a star in view. Thirdly, the book puts the amateur astronomers' observations into a wider perspective. "Twenty-Five Astronomical Observations That Changed the World" makes the observer part of that great story of discovery. Each chapter, each observing challenge, shows how to observe and then how to look with understanding. The projects begin with practicalities: where the object is, how best is it observed and with what appropriate equipment (usually a small-to-medium aperture amateur telescope, binoculars, even the naked eye). "Twenty-Five Astronomical Observations that Changed the World" guides even the inexperienced amateur astronomer - beginners can use the book - around a variety of night-sky objects, and reminds the more experienced how they can best be seen. These practical observations put us in contact with all the history and culture surrounding them: through scientific speculation and literature to those first fuzzy images made in 1959 by the Russian space probe Luna 3.

The earliest rudiments of the Astronomical Observatory are as little known as the earliest discoveries in astronomy itself. Probably the first application of instrumental observation to the heavenly bodies consisted in the simple operation of measuring the shadow of a post cast by the sun at noonday. The variations in the length of this shadow enabled the primitive astronomers to investigate the apparent movements of the sun. But even in very early times special astronomical instruments were employed which possessed sufficient accuracy to add to the amount of astronomical knowledge, and displayed considerable ingenuity on the part of the designers. Professor Newcomb[2] thus writes: "The leader was Tycho Brahe, who was born in 1546, three years after the death of Copernicus. His attention was first directed to the study of astronomy by an eclipse of the sun on August 21st, 1560, which was total in some parts of Europe. Astonished that such a phenomenon could be predicted, he devoted himself to a study of the methods of observation and calculation by which the prediction was made. In 1576 the King of Denmark founded the celebrated observatory of Uraniborg, at which Tycho spent twenty years assiduously engaged in observations of the positions of the heavenly bodies with the best instruments that could then be made. This was just before the invention of the telescope, so that the astronomer could not avail himself of that powerful instrument. Consequently, his observations were superseded by the improved ones of the centuries following, and their celebrity and importance are principally due to their having afforded Kepler the means of discovering his celebrated laws of planetary motion." The direction of the telescope to the skies by Galileo gave a wonderful impulse to the study of the heavenly bodies. This extraordinary man is prominent in the history of astronomy, not alone for his connection with this supreme invention, but also for his achievements in the more abstract parts of astronomy. He was born at Pisa in 1564, and in 1609 the first telescope used for astronomical observation was constructed. Galileo died in 1642, the year in which Newton was born. It was Galileo who laid with solidity the foundations of that science of Dynamics, of which astronomy is the most splendid illustration; and it was he who, by promulgating the doctrines taught by Copernicus, incurred the wrath of the Inquisition.
