How do you choose your first telescope? Or build one from first principles? What can the deep sky offer you season-by-season? How do you get started in astrophotography? And progress to CCD imaging? The Guide to Amateur Astronomy answers the questions of the novice and the experienced amateur astronomer in one easy-to-use and comprehensive account. Throughout the emphasis is on practical methods to get you started and then develop your skills; with lavish illustrations to show you just what is possible. This second edition of the highly successful Guide has been fully revised and updated. It now takes you from basic 'piggyback' astrophotography, through the use of a cold camera to state-of- the-art CCD imaging; from studies of the planets to the most distant objects in the Universe. From guidelines for the care and adjustment of your telescope through to lists of the spectral classification of stars, amateur astronomy societies and clubs, all the information you need for your voyage of discovery and revelation is provided in this self-contained, helpful guide.

Binary and Multiple Systems of Stars focuses on spectroscopic observational results and interpretations of binaries, and a few of multiple systems. Organized into 10 chapters, this book begins with the basic concepts and terminologies used in the study of binary and multiple systems of stars. Then, the incidence of both star systems is described. Subsequent chapters explore the properties of individual binaries, as well as the evolution and origin of such star system. This book will be a valuable reference material for astronomers, scientists in related fields, as well as graduate students.

​This handbook provides comprehensive and up-to-date information on the topic of scientific, industrial and legal metrology. It discusses the state-of-art review of various metrological aspects pertaining to redefinition of SI Units and their implications, applications of time and frequency metrology, certified reference materials, industrial metrology, industry 4.0, metrology in additive manufacturing, digital transformations in metrology, soft metrology and cyber security, optics in metrology, nano-metrology, metrology for advanced communication, environmental metrology, metrology in biomedical engineering, legal metrology and global trade, ionizing radiation metrology, advanced techniques in evaluation of measurement uncertainty, etc. The book has contributed chapters from world’s leading metrologists and experts on the diversified metrological theme. The internationally recognized team of editors adopt a consistent and systematic approach and writing style, including ample cross reference among topics, offering readers a user-friendly knowledgebase greater than the sum of its parts, perfect for frequent consultation. Moreover, the content of this volume is highly interdisciplinary in nature, with insights from not only metrology but also mechanical/material science, optics, physics, chemistry, biomedical and more. This handbook is ideal for academic and professional readers in the traditional and emerging areas of metrology and related fields.
