    Observations 26 Dec 2008 (last)
    --------------------------------------
    
    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 DSI Pro II camera will be used for high altitude
    slow moving objects. Tests seem to indicate that its sensitivity
    is comparable to the MINTRON ( possibly better) but as its not
    possible (?) to time stamp to better than 1 second accuracy the
    time resolution is not good enough for LEO objects.
    
    (1) 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.
    Used with 50mm focal length f/1.8 lens,integrating for 128 fields
    which is equivalent to a max exposure of 2.56 seconds maximum
    per image. Field of view 6.8 x 5.4 degrees.
    Individual frames are video time stamped with GPS derived signal.
    
    (2)Meade DSI Pro II Monochrome CCD camera without filters.
    using integration times of 20 sec min to 60 seconds maximum
    depending on brightness of sky in particular area.No image
    processing done but dark field applied.
    Used with 200mm focal length f/2.8 Nikkon telephoto lens,
    field of view 1.88 x 1.40 degrees. Can get to magnitude 13
    or so in less than 20 seconds exposure.
    Exposure time to nearest second inserted into image FITS header
    from PC clock which is automatically checked every minute against
    GPS signal.
    
    Site 0433 : Longitude 18.51294 deg East, Latitude -33.94058 deg,
    Elevation 10 metres-situated in Pinelands (Cape Town),South Africa

    Notes:
    --------
    (1) This concludes report for 26 December 2008. Tomorrow hope to complete
        report for 24 December 2008 then Im up to date.
    
    (2) In case the purist's jump on me some of the satellites called
        geostationary above are not - some drift east, some drift west but
        generally the orbital period is around 1 rev/day.
    
    (3) Note to self - DSCS 3-13 not seen - moved ? - priority check next
        session.
    
    (4) Some minor confusion with identities of the grouping around INSAT 3C,
        KALPANA 1 and INSAT 4CR . Predictions indicate 4 objects but only
        3 seen - has been like this since I started observing geostationary
        satellites. Another case is the ASTRA satellites where there is an
        unpredicted member which John Locker tells me is ASTRA 1L.
    
    (5) Its cloud tonight - no observing :-)))
    
    Cheers
    Greg
