Abstract

A new spectrograph (FIASCO) is in operation at the 0.9m telescope of the University Observatory Jena. This article describes the characterization of the instrument and reports its first astronomical observations, among those Li (670.8nm) detection in the atmosphere of young stars, and the simultaneous photometric and spectroscopic monitoring of variable stars.
