The finest atlas of the heavens = Der prächtigste Himmelsatlas = L'atlas céleste le plus admirable by Andreas Cellarius( Book )
17 editions published between 2006 and 2012 in 5 languages and held by 171 libraries worldwide
History's most beautiful celestial atlasThis collection of celestial maps by Dutch-German mathematician and cosmographer Andreas Cellarius (c. 1596 - 1665) brings back to life a masterpiece from the Golden Age of celestial cartography. First published in 1660 in the Harmonia Macrocosmica, the complete 29 double-folio maps and dozens of unusual details reproduced here depict the world systems of Claudius Ptolemy, Nicolaus Copernicus, and Tycho Brahe, the motions of the sun, the moon, and the planets, and the delineation of the constellations in various views. Cellarius's atlas, superbly embellished with richly decorated borders depicting cherubs, astronomers, and astronomical instruments, features some of the most spectacular illustration in the history of astronomy. This reprint includes a copiously illustrated introduction by Robert van Gent, one of the leading Cellarius experts, summarizing the history of celestial cartography from antiquity to late 17th/early 18th century and illuminating the life and work of Andreas Cellarius. Van Gent also discusses the historical and cultural context and significance of the atlas and provides detailed descriptions of the astronomical and iconographical content of the plates, allowing modern readers to fully appreciate the masterwork of Andreas Cellarius and his publisher, Johannes Janssonius. The book's detailed appendix includes a list of constellation figures with short descriptions of their origin and mythology, a list of star names found on the plates, a glossary of technical words, and a bibliography. Cellarius's exquisite renditions of the constellations will excite the astronomer in anyone

Between rhetoric and reality : instrumental practices at the astronomical observatory of the Amsterdam society 'Felix Meritis', 1786-1889 by H. J Zuidervaart( Book )
3 editions published in 2013 in English and held by 29 libraries worldwide
"Felix Meritis, the remarkable 'Temple of Enlightenment', adorns the Amsterdam canals since 1788. The building accommodated the most ambitious attempt in the Netherlands for the integration of activities regarding literature, music, the visual arts, commerce, and the sciences. What so far went unnoticed is that, from the very start, Felix Meritis was also equipped with an astronomical and meteorological observatory. In fact, it was the first scientific observatory in the Netherlands designed from the drawing board. This book describes the history of the observatory (which functioned until 1889), with a special focus on the tensions between the objectives formulated by its founding fathers and the ultimate difficult practice of scientific research. The Felix Meritis-Observatory was crucial for the training and early careers of various eighteenth- and nineteenth-century astronomers, among which Nieuwland, Van Beeck Calkoen, Moll, Keijser, Uylenbroek, and Kaiser (the father of modern Dutch astronomy)."--Cover

Tycho Brahe, Abū Ma₋shar, and the comet beyond Venus (ninth Century) A.D.) ( file )
1 edition published in 2016 in English and held by 0 libraries worldwide
From his observations of the A.D. 1572 supernova and the A.D. 1577 comet, Tycho Brahe concluded that such transient celestial objects are outside the Earth's atmosphere, and he quoted the ninth century A.D. Persian astrologer and astronomer Abū Macshar: Dixit Albumasar, Cometa supra Venerem visus fuit; i.e., the latter had reported much earlier that comets were seen beyond Venus. However, even from a more detailed Latin translation, the observations and logic behind Abū Macshar's conclusion were not understandable. We present here the original Arabic text (manuscript Ankara, Saib 199) together with our translation and interpretation: Abū Macshar reported that he had observed Venus in (or projected onto) the tail of a comet and concluded that the comet was behind Venus because he had observed the extinction of Venus due to the cometary tail to be negligible (light of Venus was unimpaired). He then concluded that the comet would be located behind Venus. He also mentioned that others had observed Jupiter and Saturn in cometary tails, so that those comets would even be located beyond those two outer planets - in the sphere of the stars. The dates of the observed close conjunctions were not mentioned; using known orbital elements for a few comets, we found a few close conjunctions between comets and planets from A.D. 770 to 868, but we cannot be sure regarding which conjunctions were reported. While the argument of Abū Macshar is not correct (as cometary tails are optically thin), the conclusion - namely that comets are outside the Earth's atmosphere and beyond the moon - is correct. This may have helped Tycho Brahe to come to his revolutionary conclusion
