Giovanni Battista Hodierna

 

Hodierna found 14 objects (9 are in the Messier catalogue); 12 were new. He used a small refractor at Palermo. All are listed in: Hodierna, G., De systemate orbis cometici, deque admirandis coeli characteribus (Palermo 1654). The discovery of NGC 2451,an open cluster in Puppis, is doubtful. Thus the credit goes to John Herschel here. M 41 was first recorded by Aristoteles.
