It is written mainly for amateur astronomers who already own or are intending to purchase a refracting telescope, but will prove useful for non-astronomical observers.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eTrade Review\u003c\/b\u003e\u003cbr\u003e\u003cp\u003eFrom the reviews:\u003c\/p\u003e\u003cp\u003e“Dr. Neil English is no stranger to the astronomical community … . His knowledge of telescope optics is highly respected, and here he endeavours to lay down all his knowledge in a concise and thorough manner. He opens the book with a wonderful overview of the history of the telescope … . this book something you really want to own, as it’s a guide not only to what is achievable by anyone with modest equipment, but also what to aspire to. Thoroughly recommended.” (Nick Howes, Astronomy Now Online, May, 2011)\u003c\/p\u003e\u003cp\u003e“Neil English opens with a brief history of refractor design, including the contributions of Lippershey, Galileo and Huygens, amongst others. … the text is clearly written and there’s plenty of useful data in the appendix. … it’s a valuable resource for anyone thinking about buying a refractor or who wants to learn more about the history and development of this iconic scientific instrument.” (Mark Parrish, BBC Sky at Night Magazine, June, 2011)\u003c\/p\u003e\u003cp\u003e“Having owned around a dozen refractors over the years–ranging from a ‘lowly’ 40mm refractor, through several antique examples to a go-to refractor–I was keen to read a book that promised to reinforce my love for ‘the prince of telescopes’. … An excellent, up-to-date book containing much more than I have outlined in this review. English communicates his passion for refractors, and the book comes to life with user accounts of refractors old and new.” (Peter Grego, Popular Astronomy, July-August, 2011)\u003c\/p\u003e\u003cp\u003e“Value to have accessible a comprehensive guide to the availability and use of refractors, which have a special attraction and romance –– especially for those who have used and appreciated the best of them. … The short but useful appendices include glossaries of terms and formulae, and data on a selection of double stars which can be used for testing refractors of various apertures. … Even for those with only the slightest interest, it would certainly inspire them.” (R.
