Title page of Tycho Brahe's Astronomiae instauratae mechanica. Brahe was the foremost astronomer of his time, particularly noted for his accurate celestial measurements.  His radial observations were consistently correct within one second of arc.  This accuracy was due in large part to the excellence of his self designed instruments, most of which are described in this book.  For a complete translation of his table of contents and listing of instruments see http://www.kb.dk/en/nb/tema/webudstillinger/brahe_mechanica/.
