In 1800, he discovered the central star in M57, the Ring Nebula in the constellation Lyra. He died in Remplin, Mecklenburg. After his death, his son, the "theatrical count", squandered his fortune and all books and instruments were sold. The best instruments were bought by Friedrich Wilhelm Bessel for the new observatory in Königsberg. One instrument is on display in the Deutsches Museum in Munich. He is honoured together with Otto Hahn by the lunar crater Hahn.
