SIM Grid Star Observations: Astrometry With a New High Dynamic Range Imaging Device

Abstract

First astrometric and photometric applications of the logarithmically scaled HDRC4 imager (developed by the Institut fur Mikroelek-tronik Stuttgart, IMS, Germany) are presented. To test the HDRC4 imager at the telescope, a cooled camera had to be constructed by modifying a camera designed by IMS. First observations were performed with various telescopes at Hamburg Observatory, Germany. These showed the dynamic range to exceed 14 mag and the sensitivity to be comparable to that of the Kodak KAF 4200 CCD at a chip temperature of -35 deg C.
