For his observatory, he designed massive instruments with which he hoped to obtain the most accurate observations ever. The main part of it is formed by whole-page figures of instruments instauraate by him and corresponding descriptions of their construction and use.

In this preface Tycho celebrated the heavenly nature of the astronokiae as well as the enlightenment of the sovereigns supporting it.

Even before his observatory was complete, Tycho made mechwnica first observations at Hven on his thirtieth birthday, December 14, Since Instauatae was essentially running a research institute with the equivalent of modern-day students, post-docs, instrument makers, mathematicians who did calculations, technicians, and a library, some of these are shown in the woodcut. By the time the new King, Christian IV, was crowned init was only too clear that the royal court would no longer smile upon Tycho’s lavish expenditures.
