    Observations 10 JAN 2012
    ----------------------------
    
    Cosatrak 1 (Computerised satellite Tracking System).
    Camera mount now carries two systems that can be operated
    together as two totally different sytems and computers used.
    Generally the CCD camera will be used for high altitude
    slow moving objects, whilst video will be used for LEO sats.
    
    FLI ML8300M CCD camera with mechanical shutter + Trimble GPS
    Used with SKYWATCHER 102mm f/5 - focal length 502.3mm, field of
    view 122.7 x 92.6 arc minutes, image scale 8.86 arc sec/pixel.
    Camera being used in 4 bin mode to match my poor seeing.All
    exposures 20 seconds (limited by bright 1st quarter moon and city
    lit sky). Exposure time to nearest second inserted into image FITS
    header from PC clock.
    Images processed and automatically reduced using APEX.

    NOTES:
    ---------
    (1) Very bright moon so only tried bright objects and looking for PAN
        and other "lost" objects
    
    (2) Did a search for PAN but nothing really obvious.
    
    (3) The "Confusion reigns" objects include ASTRA 2D,ASTA 1N, ASTRA 2A,
        ASTRA 2B and EUROBIRD in a tight group. Since they are not important
        I have not battled to try and sort out which is which.
    
    (4) Object #18 I am not sure about. It may or may not be a dead pixel.
        I suspect it is.
    
    (5) Tried using the CCD camera on a fast moving object - OTV2-1. Since
        the mechanical shutter/GPS system reports as being accurate to 50
        milliseconds it should be okay. I also used APEX to process these
        observations except for those that have code 56 which were done
        manually. If anything looks "odd" please inform me otherwise I
        shall assume it is OK to use the FLI ML8300M CCD camera on leo sats.
    
    Cheers
    Greg
