He co-discovered the Phoenix Dwarf galaxy ( with Richard M . West ) , and in 1976 also discovered the Eridanus Globular Cluster , one of the most distant globular clusters in the galactic halo . In 1980 , he discovered a type-II supernova in the galaxy NGC 1255 . However , "Schuster's Spiral" ( Horologium Dwarf ) is not named after him , but a different Schuster .
