This book, first published in 1997, is for telescope owners wanting to improve their skills and make observations of real and lasting scientific value.
With over 100,000 copies sold since first publication, this is one of the most popular astronomy books of all time. It is a unique guidebook to the night sky, providing all the information you need to observe a whole host of celestial objects. With a new spiral binding, this edition is even easier to use outdoors at the telescope and is the ideal beginner's book. Keeping its distinct one-object-per-spread format, this edition is also designed for Dobsonian telescopes, as well as for smaller reflectors and refractors, and covers Southern hemisphere objects in more detail. Large-format eyepiece views, positioned side-by-side, show objects exactly as they are seen through a telescope, and with improved directions, updated tables of astronomical information and an expanded night-by-night Moon section, it has never been easier to explore the night sky on your own. Many additional resources are available on the accompanying website, www.cambridge.org/turnleft.
This book provides all the essential and best elements of Kidger's many courses taught worldwide on lens and optical design. It is written in a direct style that is compact, logical, and to the point--a tutorial in the best sense of the word. "I read my copy late last year and read it straight through, cover to cover. In fact, I read it no less than three times. Its elegant expositions, valuable insights, and up-front espousal of pre-design theory make it an outstanding work. It's in the same league with Conrady and Kingslake." Warren Smith.
This 1995 guide is packed with practical tips on how to obtain the highest resolution in your astrophotography.
The book that taught thousands of people about astrophotography has been completely revised and updated in this second edition. It covers everything you need to know to capture stunning images of deep-sky objects with a DSLR or CCD camera: The fundamental concepts of imaging and their impact on the final image How to pick a telescope and camera How to get set up and take the images Where and when to find the best objects in the night sky How to process images using Adobe Photoshop(R) and PixInsight(R) Start-to-finish examples of image processing Full-color with over 300 illustrations.
A valuable reference that fills a number of niches including that of a buyer's guide, technical desk reference and observer's field guide. It documents the past market and its evolution, right up to the present day. In addition to appealing to practical astronomers - and potentially saving them money - it is useful both as a historical reference and as a detailed review of the current market place for this bustling astronomical consumer product. What distinguishes this book from other publications on astronomy is the involvement of observers from all aspects of the astronomical community, and also the major manufacturers of equipment. It not only catalogs the technical aspects of the many modern eyepieces but also documents amateur observer reactions and impressions over the years, using many different eyepieces. Eyepieces are the most talked-about accessories and collectible items available to the amateur astronomer. No other item of equipment commands such vigorous debate, or has evolved into such a remarkable array of forms and functions. 'Choosing and Using Astronomical Eyepieces' provides a vast amount of reference material to point readers towards the best buys and the right eyepieces for different kinds of observing.
This is an informative, up-to-date and well-illustrated guide to planetary observations for amateurs. After a brief description of the solar system and a chapter on the celestial sphere, readers are shown how to choose, test and use a telescope with various accessories and how to make observations and record results. For each planet and the asteroids, details are given of observational techniques, together with suggestions for how to make contributions of scientific value. From a general description and detailed observational history of each planet, observers can anticipate what they should see and assess their own observations. The chapter on planetary photography includes the revolutionary use of videography, charge coupled devices and video-assisted drawing. There are also chapters on making maps and planispheres and on photoelectric photometry.
What can we learn about modern Chinese history by reading a marginalized set of materials from a widely neglected period? In Republican Lens, Joan Judge retrieves and revalorizes the vital brand of commercial culture that arose in the period surrounding China’s 1911 Revolution. Dismissed by high-minded ideologues of the late 1910s and largely overlooked in subsequent scholarship, this commercial culture has only recently begun to be rehabilitated in mainland China. Judge uses one of its most striking, innovative—and continually mischaracterized—products, the journal Funü shibao (The women’s eastern times), as a lens onto the early years of China’s first Republic. Redeeming both the value of the medium and the significance of the era, she demonstrates the extent to which the commercial press channeled and helped constitute key epistemic and gender trends in China’s revolutionary twentieth century. The book develops a cross-genre and inter-media method for reading the periodical press and gaining access to the complexities of the past. Drawing on the full materiality of the medium, Judge reads cover art, photographs, advertisements, and poetry, editorials, essays, and readers’ columns in conjunction with and against one another, as well as in their broader print, historical and global contexts. This yields insights into fundamental tensions that governed both the journal and the early Republic. It also highlights processes central to the arc of twentieth-century knowledge culture and social change: the valorization and scientization of the notion of "experience," the public actualization of "Republican Ladies," and the amalgamation of "Chinese medicine" and scientific biomedicine. It further revives the journal’s editors, authors, medical experts, artists, and, most notably, its little known female contributors. Republican Lens captures the ingenuity of a journal that captures the chaotic potentialities within China’s early Republic and its global twentieth century.
This book provides a step-by-step guide of how anyone can capture and produce beautiful astronomical images, for beginners and professionals alike.
Michael Swanson’s online discussions with literally thousands of NexStar owners made it clear that there was a desperate need for a book such as this – one that provides a complete, detailed guide to buying, using and maintaining NexStar telescopes. Although this book is highly comprehensive, it is suitable for beginners – there is a chapter on "Astronomy Basics" – and experts alike. Celestron’s NexStar telescopes were introduced in 1999, beginning with their first computer controlled "go to" model, a 5-inch. More models appeared in quick succession, and Celestron’s new range made it one of the two dominant manufacturers of affordable "go to" telescopes.
