The Moon presents a broad array of tone, texture, and form. Capturing this in a painting or sketch at the eyepiece of a telescope - or even with binoculars - develops observational skills, leaves a record of the observation, and can also be a delightful and rewarding pastime. However, the choice of media available is extensive (acrylic paint, oils, pen, charcoal, etc., and even computer art programs), and there is no existing text that fully explains all lunar sketching and painting techniques in each respective medium. This beautiful and graphically rich book fulfills this requirement. It presents detailed step-by-step instructions, in the form of illustrated tutorials for every major medium employed to represent the Moon. It also provides practical advice on how to sketch outdoors at night (not ideal conditions for an artist!).This is easily the most extensive book on the subject of lunar art for amateur astronomers, particularly those observing through a telescope. The diverse features of the lunar surface will attract and entice readers to review the number of different media presented, exciting and inspiring them with the possibilities of learning to depict all of the fascinating aspects of Earth\'s very own satellite. There are currently thousands of amateur astronomers around the world engaged in astrophotography at a sophisticated level. Their ranks far outnumber professional astronomers doing the same and their contributions both technically and artistically are the dominant drivers of progress in the field today. This book is a unique collaboration of individuals world-renowned in their particular area and covers in detail each of the major sub-disciplines of astrophotography. This approach offers the reader the greatest opportunity to learn the most current information and the latest techniques directly from the foremost innovators in the field today.Lessons from the Masters includes a brilliant body of recognized leaders in astronomical imaging, assembled by Robert Gendler, who delivers the most current, sophisticated and useful information on digital enhancement techniques in astrophotography available today. Each chapter focuses on a particular technique, but the book as a whole covers all types of astronomical image processing, including processing of events such as eclipses, using DSLRs, and deep-sky, planetary, widefield, and high resolution astronomical image processing. Recognized contributors include deep-sky experts such as Jay GaBany, Tony Hallas, and Ken Crawford, high-resolution planetary expert Damian Peach, and the founder of TWAN (The World at Night) Babak A. Tafreshi.A large number of illustrations (150, 75 in color) present the challenges and accomplishments involved in the processing of astronomical images by enthusiasts. Astronomical Spectroscopy for Amateurs is a complete guide for amateur astronomers who are looking for a new challenge. After a brief overview of the development of spectroscopes and an introduction to the theory of stellar spectra, the book goes on to examine the various types of spectroscopes available to amateurs. Next, practical sections address all aspects of setting-up and using various types of commercially-available and home-built spectroscopes. A final part gives detailed instructions for the design and construction of three different spectroscopes, along with the necessary design theory (minimal math). The home-made spectroscopes have performance capabilities near or equal to commercial units but are constructed using basic hand tools for a fraction of the cost! This up-to-date practical spectroscopy book will enable amateur astronomers to develop the skills and equipment needed to prepare scientifically acceptable spectra data, and to make a valuable contribution to ProAm projects.
