No longer are heavy, sturdy, expensive mounts and tripods required to photograph deep space. With today's advances in technology, all that is required is an entry-DSLR and an entry level GoTo telescope. Here is all of the information needed to start photographing the night sky without buying expensive tracking mounts. By using multiple short exposures and combining them with mostly 'freeware' computer programs, the effect of image rotation can be minimized to a point where it is undetectable in normal astrophotography, even for a deep-sky object such as a galaxy or nebula. All the processes, techniques, and equipment needed to use inexpensive, lightweight altazimuth and equatorial mounts and very short exposures photography to image deep space objects are explained, step-by-step, in full detail, supported by clear, easy to understand graphics and photographs. Currently available lightweight mounts and tripods are identified and examined from an economic versus capability perspective to help users determine what camera, telescope, and mount is the best fit for them. A similar analysis is presented for entry-level telescopes and mounts sold as bundled packages by the telescope manufacturers. This book lifts the veil of mystery from the creation of deep space photographs and makes astrophotography affordable and accessible to most amateur astronomers.

It details the evolution of the large parabolic dish antennas, from the initial 26-m operation at L-band (960 MHz) through the current Ka-band (32 GHz) systems. Primarily used for telecommunications, these antennas also support radar and radio astronomy observations in the exploration of the solar system and the universe. In addition, the author also offers thorough treatment of the analytical and measurement techniques used in design and performance assessment.

Large Antennas of the Deep Space Network represents a vital addition to the literature in that it includes NASA-funded research that significantly impacts on deep space telecommunications. Part of the prestigious JPL Deep Space Communications and Navigation Series, it captures fundamental principles and practices developed during decades of deep space exploration, providing information that will enable antenna professionals to replicate radio frequencies and optics designs.

Designed as an introduction for students in the field as well as a reference for advanced practitioners, the text assumes a basic familiarity with engineering and mathematical concepts and technical terms.

The Deep Space Communications and Navigation Series is authored by scientists and engineers with extensive experience in astronautics, communications, and related fields. It lays the foundation for innovation in the areas of deep space navigation and communications by disseminating state-of-the-art knowledge in key technologies.

The first three billion years of cosmic time were the prime epoch of galaxy formation. Characterising galaxies at this epoch is therefore crucial to achieving a major goal of modern astrophysics: to understand how galaxies such as our Milky Way emerged from the primordial density fluctuations in the early Universe and how they evolved through cosmic time. Recent major international investments in observing facilities such as the Atacama Large Millimetre Array (ALMA) and the James Webb Space Telescope (JWST) promise to provide the next leap in our understanding of this topic. This volume gathers the scientific contributions to the International Astronomical Union Symposium 352, which was devoted to this topic. The community of theoretical and observational experts discuss how we can make the most of ALMA and JWST synergies in advancing our understanding of galaxy evolution in the young Universe.

Progress in modern radio astronomy led to the discovery of space masers in the microwave range, and it became a powerful tool for studies of interstellar star-forming molecular clouds. Progress in observational astronomy, particularly with ground-based huge telescopes and the space-based Hubble Space Telescope, has led to recent discoveries of space lasers in the optical range. These operate in gas condensations in the vicinity of the mysterious star Eta Carinae (one of the most luminous and massive stars of our Galaxy). Both maser and laser effects, first demonstrated under laboratory conditions, have now been discovered to occur under natural conditions in space, too. This book describes consistently the elements of laser science, astrophysical plasmas, modern astronomical observation techniques, and the fundamentals and properties of astrophysical lasers. A book with such an interdisciplinary scope has not been available to date. The book will also be useful for a wider audience interested in modern developments of the natural sciences and technology.

Masers are the microwave analogue of lasers; there are many astronomical sources of natural maser emission, including gas around forming and dying stars, and around supermassive black holes. These bright sources of microwaves are fascinating in their own right and provide unique abilities to probe details of astronomical sources. Molecular maser emission studies address important questions in the formation and evolution of stars, the structure of our Milky Way Galaxy, the characteristics of supermassive black holes, and fundamental parameters of cosmology. More than 100 astronomers from around the world gathered in Cagliari, Sardinia, for IAU Symposium 336 to discuss the latest findings related to masers. These proceedings summarize state of the art observations and theories pertaining to astrophysical masers and their environments, for graduate students and researchers. As new radio telescope facilities come online, observations of masers will continue to shed light on a broad range of important astrophysical problems.

The book emphasizes physical understanding of detector operation, without being a catalog of current examples. It is self-contained but also provides a bridge to more specialized works on specific approaches; each chapter points readers toward the relevant literature. This will provide a broad and lasting understanding of the methods for detecting light that underpin so much of our technology. The book is suitable for advanced undergraduate and graduate students, and will provide a valuable reference for professionals across physics and engineering disciplines.

Over the last 50 years, a variety of techniques have been developed to add a third dimension to regular imaging, with an extended spectrum associated to every imaging pixel. Dubbed 3D spectroscopy from its data format, it is now widely used in the astrophysical domain, but also inter alia for atmospheric sciences and remote sensing purposes. This is the first book to comprehensively tackle these new capabilities. It starts with the fundamentals of spectroscopic instruments, in particular their potentials and limits. It then reviews the various known 3D techniques, with particular emphasis on pinpointing their different 'ecological? niches. Putative users are finally led through the whole observing process, from observation planning to the extensive ? and crucial - phase of data reduction. This book overall goal is to give the non-specialist enough hands-on knowledge to learn fast how to properly use and produce meaningful data when using such a 3D capability.

Covering both homemade and commercial products, this book provides the reader with simple and straightforward information about the modeling, building, and use of binoscopes. Binoscopes can be thought of as binoculars enlarged to the size of telescopes - essentially, a combination of the two. Constructing a binoscope is easier than most people think, but it still demands attention to detail and proper background knowledge. The author goes on to provide additional information about the products currently on the market, should the reader choose to purchase one instead of building it. Lastly, the book also compares binoscopes with telescopes in great detail, outlining the differences the reader can expect to see in the night sky from using both. The celestial views obtained with a binoscope, compared to a single telescope of the same aperture, are a very different experience. The new edition emphasizes the obvious advantages of viewing celestial objects through a binoscope. There are also many new photos and additional information on the latest equipment and some very special and rare equipment a collector might be interested in. Newly added cartoons and additional images of beautiful deep sky objects in each of the chapters makes reading the book a more enjoyable experience. Finally, there is a new comet discovery form and guide to follow for such discoveries, and a complete list of Messier objects for those interested in searching for these.

Three experts in the field of thin-film optics present a detailed and self-contained theoretical study of planar multilayers and how they can be effectively exploited in both traditional and modern applications. Starting with a discussion of the relevant electromagnetic optics, the fundamental optical properties of multilayers are introduced using an electromagnetic approach based on a direct solving of Maxwell's equations by Fourier transforms. This powerful approach is illustrated through the comprehensive description of two of the most important phenomena in multilayers, i.e. giant field enhancement in dielectric stacks and light scattering from thin-film optical filters. The same approach is extended to the description of the operation of planar microcavities and the balance of energy between radiated and trapped light. This book will be valuable to researchers, engineers and graduate students with interests in nanophotonics, optical telecommunications, observational astronomy and gravitational wave detection.

Between 1650 and 1750, four Catholic churches were the best solar observatories in the world. Built to fix an unquestionable date for Easter, they also housed instruments that threw light on the disputed geometry of the solar system, and so, within sight of the altar, subverted Church doctrine about the order of the universe. A tale of politically canny astronomers and cardinals with a taste for mathematics, The Sun in the Church tells how these observatories came to be, how they worked, and what they accomplished. It describes Galileo's political overreaching, his subsequent trial for heresy, and his slow and steady rehabilitation in the eyes of the Catholic Church. And it offers an enlightening perspective on astronomy, Church history, and religious architecture, as well as an analysis of measurements testing the limits of attainable accuracy, undertaken with rudimentary means and extraordinary zeal. Above all, the book illuminates the niches protected and financed by the Catholic Church in which science and mathematics thrived. Superbly written, The Sun in the Church provides a magnificent corrective to long-standing oversimplified accounts of the hostility between science and religion.

An observatory and a lighthouse form the nexus of this major new investigation of science, religion, and the state in late Ottoman Egypt. Astronomy, imperial bureaucrats, traditionally educated Muslim scholars, and reformist Islamic publications, such as The Lighthouse, are linked to examine the making of knowledge, the performance of piety, and the operation of political power through scientific practice. Contrary to ideas of Islamic scientific decline, Muslim scholars in the nineteenth century used a dynamic tradition of knowledge to measure time, compute calendars, and predict planetary positions. The rise of a 'new astronomy' is revealed to owe much to projects of political and religious reform: from the strengthening of the multiple empires that exercised power over the Nile Valley; to the 'modernization' of Islamic centers of learning; to the dream of a global Islamic community that would rely on scientific institutions to coordinate the timing of major religious duties.

The Cassini Orbiter mission, launched in 1997, has provided state-of-the-art information into the origins and workings of Saturn. Drawing from new discoveries and scientific insight from the mission, this book provides a detailed overview of the planet as revealed by Cassini. Chapters by eminent planetary scientists and researchers from across the world comprehensively review the current state of knowledge regarding Saturn's formation, interior, atmosphere, ionosphere, thermosphere and magnetosphere. Specialised chapters discuss the planet's seasonal variability; the circulation of strong zonal winds; the constantly changing polar aurorae; and the Great Storm of 2010-2011, the most powerful convective storm ever witnessed by humankind. Documenting the latest research on the planet, from its formation to how it operates today, this is an essential reference for graduate students, researchers and planetary scientists.

High time-resolution astrophysics (HTRA) involves measuring and studying astronomical phenomena on timescales of seconds to milliseconds. Although many areas of astronomy, such as X-ray astronomy and pulsar observations, have traditionally required high time-resolution studies, HTRA techniques are now being applied to optical, infrared and gamma-ray wavelength regimes, due to the development of high efficiency detectors and larger telescopes that can gather photons at a higher rate. With lectures from eminent scientists aimed at young researchers and postdoctorate students in observational astronomy and astrophysics, this volume gives a practical overview and introduction to the tools and techniques of HTRA. Just as multi-spectral observations of astrophysical phenomena are already yielding new scientific results, many astronomers are optimistic that exploring the time domain will open up an important new frontier in observational astronomy over the next decade.

Astrometry has historically been fundamental to all the fields of astronomy, driving many revolutionary scientific results. ESA's Gaia mission is astrometrically, photometrically and spectroscopically surveying the full sky, measuring around a billion stars to magnitude 20, to allow stellar distance and age estimations with unprecedented accuracy. With the complement of radial velocities, it will provide the full kinematic information of these targets, while the photometric and spectroscopic data will be used to classify objects and astrophysically characterize stars. IAU Symposium 330 reviews the first 2.5 years of Gaia activities and discusses the scientific results derived from the first Gaia data release (GDR1). This significant increase in the precision of the astrometric measurements has sharpened our view of the Milky Way and the physical processes involved in stellar and galactic evolution. To many, the Gaia revolution heralds a transformation comparable to the impact of the telescope's invention four centuries ago.

The New General Catalogue (NCG), originally created in 1888, is the source for referencing bright nebulae and star clusters, both in professional and amateur astronomy. With 7840 entries, it is the most-used historical catalogue of observational astronomy, and NGC numbers are commonly used today. However, the fascinating history of the discovery, observation, description and cataloguing of nebulae and star clusters in the nineteenth century has largely gone untold, until now. This well-researched book is the first comprehensive historical study of the NGC, and is an important resource to all those with an interest in the history of modern astronomy and visual deep-sky observing. It covers the people, observatories, instruments and methods involved in nineteenth-century visual deep-sky observing, as well as prominent deep-sky objects. The book also compares the NGC to modern object data, demonstrating how important the NGC is in observational astronomy today.

The second edition of this popular text provides undergraduates with a quantitative yet accessible introduction to the physical principles underlying the collection and analysis of observational data in contemporary optical and infrared astronomy. The text clearly links recent developments in ground- and space-based telescopes, observatory and instrument design, adaptive optics, and detector technologies to the more modest telescopes and detectors that students may use themselves. Beginning with reviews of the most relevant physical concepts and an introduction to elementary statistics, students are given the firm theoretical foundation they need. New topics, including an expanded treatment of spectroscopy, Gaia, the Large Synoptic Survey Telescope, and photometry at large redshifts bring the text up to date. Historical development of topics and quotations emphasize that astronomy is both a scientific and a human endeavour, while extensive end-of-chapter exercises facilitate the students' practical learning experience.

Originally published in 1957, this book presents symposium number 4, organised by the International Astronomical Union, held on 25th-27th August 1955 at the Jodrell Bank Experimental Station of the University of Manchester. This volume contains all but two of the papers presented and one contribution, paper 16, has been added at the editor's request. Furthermore, 'many papers have been improved as a result of discussion at the symposium or by the inclusion of data not available in August 1955'. The papers are broad in scope and detailed; chapter titles include, 'Spectral line investigations', 'Galactic structure and statistical studies of point sources' and 'Meteors and planets'. Diagrams are included for reference throughout. This book will be of significant value to astronomy scholars as well as to anyone with an interest in physics, cosmology and the history of science.
