    Observations 03 Nov 2008
    --------------------------------
    
    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 sesnitivity
    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 145mm focal length f/2.5 lens,integrating for 128 frames
    which is equivalent to a max exposure of 2.56 seconds maximum
    per image. Field of view 2.5 x 1.8 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.

    Elevation 10 metres-situated in Pinelands (Cape Town),South Africa

    Notes:
    -------
    
    (1) One of those RARE nights-conditions good, crescent moon not a problem
    
    (2) Problems with identifying which is which
    
            DSCS 3-13 vs INTELSAT 904 so gave two positions for each
            DSCS 3-12 vs ATLANTIC BIRD 1 - again two positions for each
    
    (3) #96044 - when trying to locate the field I got one bright flash
        but at the time the camera was not saving images. I then sat on the
        area for more than 10 minutes and saw no more flashes and nothing
        captured in long exposures. The position was very close to that of
        #96044 (int position) so pretty certain it was the candidate but it
        would appear this is a very faint object ( fainter than mag +14) with
        rare bright flashes.
    
    (4) #96084 - nothing seen
    
    (5) #96088 - difficult- slow variable, mostly fainter than mag +14
    
    (6) FLEETSATCOM 1 (#10669) - two flashes seen - of which one captured so
        one position. Invisible rest of time
    
    (7) BSAT 1 (#25312) looks like a nice regular flasher with some flashes
        as bright as mag +3.
    
    (8) COSMOS 1124 (#11509) nice regular flasher, visible entire cycle,
        ranging from about mag 7 to about mag 10 - short sharp periodic flash
        period several seconds ( did not time)
    
    (9) UNKNOWN seen crossing top corner of one frame, slight magnitude
        variation - looks like a GTO object near apogee.
    
    Cheers
    Greg
