The Application of the No.1 CCD System to the Coude Spectrograph at Yunnan Observatory

    Graphical Abstract
    • Abstract
  • The optical layout and the mechamical adjustment installation of the Coude spectrograph using the CCD system as a receiver at the f=1900mm camera are described in this paper. The preliminary observation results in the range of 3900Å to 5200Å are also presented.The observed results show that the limited magnitude of the system is improved by 1.m5-3.m0 compared with the photographic emulsion of Kodak Ⅱa-O or 103a-F.
