Bartsch was born in Lauban (Lubań) in Lusatia. He was taught how to use the astrolabe by Sarcephalus (Christopher Hauptfleisch), a librarian in Breslau (Wrocław). He also studied astronomy and medicine at the University of Strassburg (Strasbourg). In 1624 Bartsch published several star charts, titled Usus astronomicus planisphaerii stellati, which included several new constellations introduced around 1613 by Petrus Plancius on a celestial globe published by Pieter van den Keere. These included Camelopardalis, Crux, Monoceros, and Reticulum. Bartsch married Johannes Kepler's daughter Susanna on 12 March 1630 and helped Kepler with his calculations. After Kepler's death in 1630, Bartsch edited Kepler's posthumous work Somnium. He also helped gather money from Kepler's estate for his widow. Bartsch died in Lauban in 1633
