Book Description
Excerpt from An Introduction to the Study of Variable Stars During the past few years the subject of variable stars has become increasingly interesting to the amateur who is the owner of a telescope, as well as to the average college student who has some knowledge of astronomy, while to the research worker it offers many line of investigation which are full of promise. However, so complex is the subject, and so diverse the principles involved in a complete understanding of it, that extensive reading in several different directions is required as a foundation. It is with the purpose of supplying this need as well as of making an important and attractive branch of astronomy accessible to the student that the present volume has been prepared. It is the outcome of several years of teaching the subject in Vassar College, for which the material was primarily collected. This material is scattered throughout various periodicals in the form either of research papers or quite popular articles, intended to give directions for observation to owners of small telescopes. A large amount of historical matter is also included, which is taken from sources not within easy reach of the general reader. Mention may be made of some of the subjects treated, which are introductory to the study of stellar variation, such as the study of the Durchmusterung charts, photometry in all its branches, spectroscopy, and star color. The purpose of the present volume is to consider all of these points, and in particular to give in as simple and clear a form as possible a full presentation of the physical principles upon which many of the instruments and methods of investigation are based, principles such as those of polarized light, spectrum analysis, the formation of the photographic image, and photo-electricity.

Book Description
David Levy's entertaining, well-researched book is aimed at the amateur enthusiast who likes to learn enjoyably. Beginning with advice on binoculars and telescopes, and how to observe the night sky effectively, the author goes on to describe thoroughly the field of variable star observation, a field in which amateurs have made important contributions. He shows how to interpret variations in light output in terms of the life of a star, from birth through to sometimes violent death. All of the major variable stars are described and classified, as well as other variable objects such as active galaxies, asteroids, comets and the sun. The book also contains a guide to the seasonal night sky. Throughout, practical observations serve to complement the text, producing an exciting, very readable introduction to this fascinating subject.

Book Description
Observing variable stars is one of the major contributions amateur astronomers make to science. There are 36,000 variable stars listed in the General Catalogue of Variable Stars, so it is clearly impossible for the limited number of professional observatories to target even the majority of them. That's where amateur astronomers come in - thousands of them turning their telescopes to the sky every night. Variable star observing is the most popular of "real science" activities for amateurs, and Gerry Good's book provides everything needed. The first part of the book provides a highly detailed account of the various classes of variable star, with examples, illustrations and physical descriptions. The second section covers practical aspects of observing, everything from preparation and planning, through observing techniques, to data management and reduction.

Book Description
Long-term monitoring is of fundamental significance in solving many important problems in astrophysics and, furthermore, has unequalled value in extending observational runs with small telescopes for the education of young astronomers in order to teach them how to secure high-quality observational data over many years. The Impact of Long-Term Monitoring on Variable Star Research contains reports based on the analysis of data collected in the visible, IR and radio measurement ranges, as well as the design and history of well known photometric systems. Though the reporting of novel results forms an important part of the book, there are also reports of eight discussion sessions covering more general areas, such as extinction monitoring, the problems of archival storage of astronomical data, service observation, the role played by long-term monitoring in graduate teaching and thesis supervision, the interplay between the great observational effort and theory, the contribution of LTM to new knowledge of fundamental data, and the increasing decommissioning of telescopes of modest aperture.

Book Description
Compact and affordable small telescopes have boosted the enthusiasm of amateur astronomers to the level of professionalism. The nature of Variable Stars can be well understood through Photometry and Spectroscopy using compact back end instruments. Small telescope observations are complementary to the astronomers using large telescopes for their research. Such observations made from locations with low level atmospheric and light pollution are of great value from astronomical point of view. With Variable Stars as observing targets in general, photoelectric photometry of about a dozen RS CVn stars was undertaken by JES Observatory with a small optical telescope of 30 cm diameter, as a part of doctoral work submitted to Dr.B.A.M. University, Aurangabad. The JESO has also participated in the International Campaign of an eclipsing binary system, Epsilon Aurigae, during 2009-11. It has conducted several Outreach Activities and organized workshops through interaction with IUCAA, Pune. The book covers basic concepts of Photoelectric Photometry and should be useful to small telescope users in universities and colleges as well as amateur astronomers.

Book Description
This title details the essential roles that small telescopes should play in 21st century science and how their future productivity can be maximized. Over 70 experts from all corners of the international astronomical community have created a reference on the future of big science with small telescopes. at national facilities and their omission from national science priority studies, the oft-lamented demise of the small telescope has been greatly exaggerated. In fact, the future of these workhorses of astronomy will be brighter than ever if creative steps are taken now. This three-volume set defines essential roles that small telescopes should play in 21st century science and the ways in which a productive future for them can be realized. A wide cross-section of the astronomical community has contributed to a definitive assessment of the present and a vision for the future. radio- and space-based facilities face problems in scientific prioritization and funding. It highlights how current small facilities are evolving to meet the scientific priorities and economical realities of the 21st century through standardization of instrumentation, use of off-the-shelf technology, specialization, optical improvements, new modes of scheduling, automation, and internet access.
