Download or read book Choosing and Using a Refracting Telescope written by Neil English and published by Springer Science & Business Media. This book was released on 2010-09-28 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Choosing and Using a Refracting Telescope has been written for the many amateur astronomers who already own, or are intending to purchase, a refracting telescope – perhaps to complement their existing arsenal of larger reflecting telescopes – or for the specialist who requires a particular refractor for serious astronomical applications or nature studies. Four hundred year ago, during the winter of 1609, a relatively unknown Italian scientist, Galileo Galilei designed a spyglass with two crude lenses and turned it skyward. Since then, refractors have retained their dominance over all types of reflector in studies of the Moon, planets and double stars because of the precision of their optics and lack of a central obstruction in the optical path, which causes diffraction effects in all commercially-made reflectors. Most mature amateur astronomers got started with a 60mm refractor, or something similar. Thirty years ago, there was little choice available to the hobbyist, but in the last decade long focus crown-flint achromats have moved aside for some exquisitely crafted apochromatic designs offered by leading commercial manufacturers. There has been a huge increase in the popularity of these telescopes in the last few years, led by a significant increase in the number of companies (particularly, William Optics, Orion USA, StellarVue, SkyWatcher and AstroTech) who are now heavily marketing refractors in the amateur astronomical magazines. In Choosing and Using a Refracting Telescope, well-known observer and astronomy writer Neil English celebrates the remarkable history and evolution of the refracting telescope and looks in detail at the instruments, their development and their use. A major feature of this book is the way it compares not only different classes of refractor, but also telescopes of each class that are sold by various commercial manufacturers. The author is perhaps uniquely placed to do this, having used and tested literally hundreds of different refracting telescopes over three decades. Because it includes many diverse subjects such as imaging with consumer-level digital cameras, imaging with webcams, and imaging with astronomical CCD cameras – that are not covered together in equal depth in any other single volume – Choosing and Using a Refracting Telescope could become the ‘refractor bible’ for amateur astronomers at all levels, especially those who are interested in imaging astronomical objects of every class.

Download or read book Choosing and Using Astronomical Eyepieces written by William Paolini and published by Springer Science & Business Media. This book was released on 2013-08-23 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Sketching the Moon written by Richard Handy and published by Springer Science & Business Media. This book was released on 2011-12-11 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: For anyone artistically inclined, observing the Moon and attempting to sketch or paint it can easily become a passion. 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.

Download or read book Binocular Astronomy written by Stephen Tonkin and published by Springer Science & Business Media. This book was released on 2007-04-05 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains everything an astronomer needs to know about binocular observing. The book takes an in-depth look at the instruments themselves. It has sections on evaluating and buying binoculars and binocular telescopes, their care, mounting, and accessories. In addition there is a selection of fifty fine objects to be seen with 50mm and 100mm binoculars. The advantages of using both eyes for astronomical observing are many and considerable, largely because of the way the human brain processes visual information. This book enables the astronomer to maximize those advantages.

Download or read book The Astronomer s Chair written by Omar W. Nasim and published by MIT Press. This book was released on 2021-09-21 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: The astronomer’s observing chair as both image and object, and the story it tells about a particular kind of science and a particular view of history. The astronomer’s chair is a leitmotif in the history of astronomy, appearing in hundreds of drawings, prints, and photographs from a variety of sources. Nineteenth-century stargazers in particular seemed eager to display their observing chairs—task-specific, often mechanically adjustable observatory furniture designed for use in conjunction with telescopes. But what message did they mean to send with these images? In The Astronomer’s Chair, Omar W. Nasim considers these specialized chairs as both image and object, offering an original framework for linking visual and material cultures. Observing chairs, Nasim ingeniously argues, showcased and embodied forms of scientific labor, personae, and bodily practice that appealed to bourgeois sensibilities. Viewing image and object as connected parts of moral, epistemic, and visual economies of empire, Nasim shows that nineteenth-century science was represented in terms of comfort and energy, and that “manly” postures of Western astronomers at work in specialized chairs were contrasted pointedly with images of “effete” and cross-legged “Oriental” astronomers. Extending his historical analysis into the twentieth century, Nasim reexamines what he argues to be a famous descendant of the astronomer’s chair: Freud’s psychoanalytic couch, which directed observations not outward toward the stars but inward toward the stratified universe of the psyche. But whether in conjunction with the mind or the heavens, the observing chair was a point of entry designed for specialists that also portrayed widely held assumptions about who merited epistemic access to these realms in the first place. With more than 100 illustrations, many in color; flexibound.

Download or read book So You Want a Meade LX Telescope written by Lawrence Harris and published by Springer Science & Business Media. This book was released on 2010-07-20 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computers and Astronomy Perhaps every generation of astronomers believes that their telescopes are the best that have ever been. They are surely all correct! The great leap of our time is that computer-designed and machined parts have led to more accurately made com- nents that give the astronomer ever better views. The manual skills of the craftsman mirror grinder have been transformed into the new-age skills of the programmer and the machine maker. (The new products did not end the work of craftsman te- scope makers, though. Many highly skilled amateur/professional opticians cont- ued to produce good-quality mirrors that are still seen today. ) Amateur-priced telescopes are now capable of highly accurate tracking and computer control that were once only the province of professionals. This has greatly increased the p- sibilities of serious astronomy projects for which tailor-made software has been developed. Add a CCD camera to these improved telescopes (see Chap. 3), and you bring a whole new dimension to your astronomy (see Fig. 1. 1). Look Before You Leap! But first, a word of caution. Unless you are already familiar with astronomy and basic telescopes, it is not wise to start spending large amounts of money on a we- featured telescope. Such an instrument might otherwise be subsequently abandoned due to a perceived overcomplexity coupled with a waning interest.
