MICADO is targeted to be one of the first light  instruments of the Extremely Large Telescope (ELT) and it will embrace  imaging, spectroscopic and astrometric capabilities including their  calibration. The astrometric requirements are particularly ambitious  aiming for 50 µas differential precision within a single epoch. After a  complete overview of the MCA subsystems, their functionalities, design  and status, particular emphasis will be placed on the ongoing efforts (both prototype testing and simulation) on the astrometric calibration  of the optical distortions of the instrument and the telescope.[[BR]][[BR]]Presentation: English[[BR]][https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/AlteVortraege2018S1/2018-03-02_MCA.pdf Slides: English][[BR]]Questions: German, English ||

Bohnenberger: [[BR]]Astronomer, Geodesist and Inventor of the Gyroscope'''[[BR]][[BR]]Johann Gottlieb Friedrich Bohnenberger (1765-1831) was a professor of physics, mathematics, and astronomy at the University of Tuebingen, the scientific head surveying officer of the early Kingdom of Wuerttemberg, and an important German astronomer of the 19th century. He made both major contributions to introducing modern geodesy in Germany and invented various physical instruments. The "Machine of Bohnenberger" is considered the first gyro with cardanic suspension and forms the precursor of Foucault’s Gyroscope of 1852. This presentation discusses this apparatus as well as the life and the scientific work of J.G.F. Bohnenberger.[[BR]][[BR]]Presentation: German[[BR]][https://svn.mpia.de/trac/gulli/att/raw-attachment/wiki/AlteVortraege2018S1/2018-03-09_Bohnenberger.pdf Slides: English][[BR]]Questions: German, English ||

+|| '''16.03.2018[[BR]](11hrs, MPIA Hoersaal)''' || '''Klaus Meisenheimer''' || '''MATISSE — its Way to "First Light" and Beyond [[BR]]'''[[BR]]MATISSE is the next MIR instrument for ESO's VLT Interferometer. Seven European institutes are cooperating in this project since 2011. After the integration of the Dutch "cold optics" in the cryostats at MPIA and the delivery to OCA Nice end of 2014, MATISSE made a rather laborious rise to its Preliminary Acceptance Europe (PAE) in September 2017. After the arrival on Paranal end of October the integration and commissioning went smoothly and culminated in the coherent 4-telescope-observation of Sirius on February 19th. [[BR]][[BR]]Klaus  Meisenheimer will explain functionality and major advantages of MATISSE and he will recapitulate the developements up to "First Light". An outlook will highlight the fascinating scientific possibilities for MPIA and its partners from 2019 on.
