ARGOS the Advanced Rayleigh guided Ground layer adaptive Optics System for the LBT (Large Binocular Telescope) was named after this giant, because the system will also have a lot of eyes. Recently, the first of these eyes were taken into operation. Now, ARGOS is watching with "Argos-eyes" for LUCI. [[BR]][[BR]]One year after the first laser stars have been projected on sky, the "Loop" could be closed on one side of the LBT simultaneously on three guide stars. The performance of the system was better than expected. A factor two improvement in image quality was the goal, but reality exceeded this prediction. Nevertheless, the images look not that spectacular than of other Adaptive Optics Systems, because ARGOS does not goal on the diffraction limit but on increasing the slit throughput for spectroscopy in a large range of atmospheric conditions. [[BR]][[BR]]Wolfgang Gaessler will present the project and its current status. He will tell us which problems are solved and which still have to be solved. And we will learn when ARGOS will be ready and what one can do with it. But the question is: Will ARGOS have the same fate as Argos? In the Greek mythology, Zeus ordered Hermes to kill Argos to free Io. Hermes succeed. In the real world it also looks like that some Argeiphontes (slayer of Argos) start to gather!
