  We report on the first scientific results with the recently commissioned
PUCHEROS spectrograph, mounted at the 50cm telescope of the Pontificia
Universidad Catolica near Santiago, Chile. A hitherto unknown candidate Be+sdO
binary was identified, omicron Pup. If confirmed, it would be the fourth member
of this class. Such stars have obtained their rapid rotation through binary
mass transfer and now consist of a Be star and a hot subdwarf.
