Patrick Moore, "The Amateur Astronomer" English | 2006 | ISBN: 1852338784 | True PDF | pages: 293 | 8,6 Mb Twelfth Edition *** Ai trong chúng ta cũng từng là những đứa trẻ, cũng từng ngước nhìn trời đêm và mơ về những vì sao. ***** This 2000 Edition of Sir Patrick Moore's classic book has been completely revised in the light of changes in technology. Not only do these changes include commercially available astronomical telescopes and software, but also what we know and understand about the universe. There are many new photographs and illustrations. Packs a great deal of valuable information into appendices which make up almost half the book. These are hugely comprehensive and provide hints and tips, as well as data (year 2000 onwards) for pretty well every aspect of amateur astronomy. This is probably the only book in which all this information is collected in one place. Lời nói đầu cho lần xuất bản đầu tiên 1957 Many popular books upon astronomy have been written during the past few years, but most of them cater either for the casual dabbler who is content to learn from the depths of his armchair or else for the serious amateur who already knows the main facts. What I have done, or tried to do, is to strike a happy mean. This book has been aimed at the needs of the beginner who knows nothing whatsoever, but who is nevertheless anxious to make a start with what equipment he can collect at limited cost. All astronomers, professional or amateur, were beginners once, and all have had to draw upon the experience of those who have learned before them. I feel some diffidence about offering myself as a guide, but at least I have one qualification: in my early days as an observer I made almost every mistake that it is possible to make! This explains the frequent occurrence of such phrases as "I once saw...." and "I remem- ber that when I.." I hope therefore that what I have written may prevent others from falling into the same ridiculous traps. A common fault in popular books is that too much space is devoted to the Moon and planets, and too little to the greater problems of the stars. I am well aware that I have laid myself open to precisely this criticism, but there is a reason for it. I repeat that I am writing for the amateur who wants to observe; and while the owner of a small telescope can make himself extremely useful in the lunar and planetary field, he is rather more limited with regard to stellar problems. I hope, therefore, that the fault may be forgiven. If this book has a use, it will be to the man who works with cheap and limited equipment. I have, however, given a list of more advanced works which can be consulted by anyone who wants to go more deeply into the subject. Astronomy is the most satisfying of all hobbies; taken as a class, astronomers are friendly folk. If my book persuades a few people to take a real interest in the heavens, I shall feel that it has been well worth writing. Patrick Moore August 1957 Lời mở đầu cho lần tái bản thứ 12 (có bổ sung chỉnh lý) The first edition of The Amateur Astronomer was published almost half a century ago. Other editions followed, and I hope it is fair to say that they introduced quite a number of people to astronomy. But things have changed since then. In 1957, the average amateur astronomer worked with a modest telescope and a simple camera; his main targets were the planets and some variable stars. Not so today. Electronic devices have largely replaced photographic film, telescopes are computer-controlled and the well-equipped camera can produce results equal to those of major professional observatories a few decades ago. Old-fashioned visual observers are as outdated as dinosaurs. I have to admit that I am a dinosaur, and when I was asked to prepare a new edition of this book, I had to make a decision. There was no point in catering for the electronics expert and computer user; others can do that far better than I ever could. So it was better to retain the original pattern, bringing it up to date but not attempting to go further. If you belong to the technology of the twenty-first century, this is not the book for you; otherwise - well, I hope that you will find it useful.
