Title:  el TIGRE: A new robotic spectroscopy telescope 

"el TIGRE" is a fully robotic 1.2m-telescope operated by Hamburger Sternwarte, the Universidad de Guanajuato, and the Universite de Liege at the La Luz site in central Mexico. The telescope feeds a fibre-couple echelle spectrograph providing a spectral resolution in excess of 20000 in the wavelength range between 3900 - 8800 A in two arms. The system works fully autonomously, can be fexibly scheduled, can obtain hundreds of spectra per night and reaches observing efficiencies above 90%. The Balmer lines up to Hepsilon, CaII HK and the CAII IRT triplet are covered simultaneously, thus the system is well suited for longterm activity monitoring. In the poster the el TIGRE hardware and software system is described and its performance is demonstrated by specific cool star examples.
