The design combines simplicity and portability with large-aperture prowess. Thirty years later Dobsonians remain supreme for visually observing faint deep-sky objects and are one of the best-selling large telescopes in the USA and Europe. This popularity is reflected in the recent increase of companies now heavily marketing Dobsonians, in particular, Meade (the "Lightbridge" range), Orion USA (XT Intelliscope series), and Skywatcher (Skyliner and Flextube models). This book is the ultimate guide to buying and using commercial Dobsonians, both ‘Econo‘ and ‘Primo‘ models, with in-depth accounts for the various models (plus accessories) on the market and descriptions of the many innovations that amateurs have made to optimize their telescopes‘ performance. . | | 出版日期 | Book 2011 | | 关键词 | Deep sky astronomical equipment; Deep sky visual astronomy; Dobsonian telescopes; John Dobson; Meade ref | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4419-8786-0 | | isbn_softcover | 978-1-4419-8785-3 | | isbn_ebook | 978-1-4419-8786-0Series ISSN 1431-9756 Series E-ISSN 2197-6562 | | issn_series | 1431-9756 | | copyright | Springer Science+Business Media, LLC 2011 |
