Image 1 Caption: Portrait of Johannes Kepler (1571--1630), detail from the frontispiece of the Rudolphine Tables (1627). This is Kepler in relative old age (he was 56), hoping for more gold coins from the Reichsadler (i.e, Imperial Eagle), and looking like Santa Claus.
Features:
He also wrote an account of SN 1604 (AKA Kepler) which is the last supernova observed in the Milky Way.
The Rudolphine Tables (1627) consist of a star catalogue and emphemeris tables (i.e., tables for calculating emphemerides). The Rudolphine Tables (1627) were based on Tycho Brahe's (1546--1601) observations (see Wikipedia: Tycho Brahe: Career: observing the heavens) and Kepler's 3 laws of planetary motion for heliocentric Solar System, and were by far the most accurate/precise star catalogue and emphemeris tables (i.e., tables or calculating emphemerides) ever published to 1627. But of course, were surpassed within a century since the telescopic era (1608--) of astronomy had begun. The Rudolphine Tables (1627) because they were based on the heliocentric Solar System added significant evidence for heliocentrism. The growth of such evidence from many sources convinced most astronomically interested persons in Europe that heliocentrism was probably true by circa 1660 (see Wikipedia: Heliocentrism: Age of Reason (c.1600--c.1800)).
In 1630, Germany was in the midst of the Thirty Years' War. Kepler did notice the war. It had a tendency to interfere with travel plans---and then when under bombardment ...
