Description
The star maps below represent the stars of Kepler's catalogs along with bright stars according to modern catalogs. They correspond to the same epoch and equinox as Tycho's catalogs: January 1, 1601 of the Julian calendar.
The stars from Kepler's version of Tycho's catalog and from Kepler's Secunda and Tertia Classis catalogs are represented in different colors according to the legend shown on the maps.
The representation and labeling of stars follows the conventions explained on the historical catalogs page.
