About this product

Product Information

Choosing and Using a Refracting Telescope has been written for the many amateur astromers 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 astromical applications or nature studies. Four hundred year ago, during the winter of 1609, a relatively unkwn 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 astromers 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 w heavily marketing refractors in the amateur astromical magazines. In Choosing and Using a Refracting Telescope, well-kwn observer and astromy 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 t 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 astromical CCD cameras - that are t covered together in equal depth in any other single volume - Choosing and Using a Refracting Telescope could become the 'refractor bible' for amateur astromers at all levels, especially those who are interested in imaging astromical objects of every class.

Author Biography
Dr. Neil English has a PhD in Biochemistry, and also a BSc in Physics & Astronomy. He is a Fellow of the Royal Astronomical Society, and a regular contributor to Astronomy Now (the UK's major astronomy magazine), as well as to Ireland's Astronomy & Space. He is the author of Guide to Mars (Pole Star Publications, 2003). Neil's astronomical images have been published in various magazines and journals, including a full page in the June 2006 issue of Astronomy. He has used and tested literally hundreds of refracting telescopes over a period of thirty years and has written about all aspects of this kind of instrument in the magazines. He owns and regularly uses a variety of refractors - both apochromat and achromat - which he uses from his home in rural Scotland.
