    Observations 01 March 2005  Part 2
    -------------------------------------------
    Cosatrak 1 (Computerised satellite Tracking System).
    MINTRON low light level CCD surveillance camera (0.005 lux typical
    in non integration mode) and 0.00005 lux in STARLIGHT mode with 128
    frame integration. Due to bright sky it is not worthwhile integrating
    more than 48 frames which is equivalent to an exposure of 0.96 seconds.
    
    Used with 145mm focal length f/2.5 lens giving a field of view of
    about 2.55 x 1.86 degrees and easily showing 12th magnitude stars.
    Not the best lens optically but the most useful in terms of field
    of view and magnitude penetration.
    
    Data recorded on DVD R/W disks - will be kept for 1 month and then
    re-used - just in case any queries as Im always making mistakes!

    Notes:
    ------
    (1) Sorry if my IOD observations have comments in between the data
        lines - purely for my own convenience so I know what is what.
        If being used for any analytical work its easy enough to delete
        the comments :-).
    
    (2) The known geostationaries were found in the various fields that
        I was searching for unknown high altitude satellites. Some objects
        were observed more than once because I checked several fields
        more than once. The field with the most geostationaries was that
        around 90031 which also had PAS 7, PAS 10, Cosmos 1366 and
        Eutelsat W5 which was the brightest of the lot. The PAS satellites
        supply South Africa with direct TV broadcasts.
    
    (3) The "strays" seen crossed my field of view whilst observing other
        objects.
    
    (4) Plan to track again tomorrow night but planning to automate the
        search for high altitude satellites as its taking too much time!
    
    Cheers
    Greg
