Beschreibung
At around the turn of the millennium, the introduction of the Coronado range of solar telescopes and filters heralded the ‘coming of age’ of amateur solar astronomy.
Before then, solar astronomy was mostly white-light only. Hydrogen-alpha systems were expensive and difficult to use, but today even the budget-priced Coronado PST (Personal Solar Telescope) provides a band pass of one Angstrom and is thermally stable. That means that today’s amateur solar observers can see – and image – sunspots, flares, prominences, plage, filaments, and active regions of the Sun, all in amazing detail.
Getting the very best out of a Coronado solar telescope still requires knowledge of specialist techniques and an accumulation of experience, which are what this book provides. In Observing the Sun with Coronado Telescopes, Philip Pugh has assembled a team of contributors who show just how much solar work can be done with Coronado telescopes, and explain how to get the very best from these marvellous instruments.
The spectacular solar images reproduced in this book speak for themselves – listen to the voices of the experts!
The Sun provides amateur astronomers with one of the few opportunities for daytime observation. Observing the major features of our nearest star requires the use of special telescopes that have a very narrow visible bandwidth, as narrow as 1 × 10-10 m (1 Angstrom) and centered on the absorption line of neutral hydrogen. This makes visible many major features of the Sun’s chromosphere. Such narrow-band filters were too expensive for amateur use until the introduction of the Coronado range of solar telescopes. The entry-level Coronado telescope, the PST (Personal Solar Telescope) costs under $500. In this book, a team of contributors show just how much solar observation work can be accomplished with Coronado telescopes, and explain how to get the best from these marvellous instruments. The book shows that Solar prominences, filaments, flares, sunspots, plage and active regions are all visible and can be imaged to produce spectacular solar photographs.
The first introduction to H-alpha solar observation for amateurs Dedicated to the popular Coronado range of H-alpha telescopes Contains superb images of the Sun in H-alpha taken with Coronado telescopes by top amateur astronomers Detailed sections on imaging and image-processing Covers the range of equipment from the entry level PST to advanced, but with emphasis on the low-cost models Includes supplementary material: sn.pub/extras

From the reviews:
"Observing the Sun is becoming more and more popular these days … . there’s a whole range of Coronado solar telescopes on offer. This book aims to clarify the differences between them and give you solid advice on what each one can do. … The chapters are well written and comprehensive. … this is actually a very useful resource if you’re interested in pursuing solar observing or imaging – not just if you have a scope made by Coronado in your garage. … it’s highly recommended." (Pete Lawrence, BBC Sky at Night, April, 2008)
"Philip Pugh’s new book, which includes contributions from several expert coauthors, covers more ground than its title suggests – including gear from other manufacturers. … I think it serves as a valuable reference and a worthwhile review of the current state of the art of daytime amateur astronomy." (Rick Fienberg, Sky and Telescope, July, 2008)
"This book does exactly what it says on the cover and more. It covers the whole gambit of solar observation in both red hydrogen light (hydrogen-alpha) and violet calcium light (CaK) and is profusely illustrated with telescopes, accessories and innumerable solar images. … The text is upbeat … . this is an excellent book and essential reading for all interested in this fascinating area of observation – no less in that it occurs at sociable daylight hours!" (Maurice Gavin, Astronomy Now, June, 2008)
"This book provides a wealth of useful information on choosing the right telescope, what accessories work best with those instruments, the use of cameras and CCD detectors, and the post-processing of their images. There are copious illustrations of both the instrumentation and the results … . I have no hesitation in recommending this book. For potential buyers of such telescopes this book is well worth … . Philip Pugh and his co-authors are to be congratulated on a very useful guide." (Steve Bell, The Observatory, Vol.128 (1206), October, 2008)
"This book aims to review the options available as well as briefly covering equipment from other sources. … I would be very happy to recommend this book to anyone who is considering the purchase of equipment to image our Sun in narrow-band hydrogen-alpha light. It does a good job of reviewing the options available and the best photographs really do show the amazing images that can be seen visually and recorded for later enhancement using a variety of image processing techniques and software." (Peter R. Hobson, Contemporary Physics, Vol. 50 (5), September-October, 2009)
