    Observations 02 March 2009 -all
    --------------------------------------
    
    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 indicate that its sensitivity
    is superior to the MINTRON camera 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) 145mm focal length f/2.5 lens fitted to 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.
    Image integrated for 2.56 seconds but exposure depends on sky background
    brightness. Field of view 2.5 x 1.9 degrees and showing about mag +12
    stars in "real time". Used as a finder for the 6 inch reflector.
    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.
    Used with 6 inch f/5 CELESTRON reflector modified to f/2.7 with home
    made corrector lens.Field of view 55 by 40 arc minutes and showing
    15th magnitude stars in real time.
    Exposure time to nearest second inserted into image FITS header
    from PC clock which is automatically checked every minute against
    GPS signal.

    Notes:
    ------
    (1) After about 3-4 weeks continuous mountain fires in the vicinity which
        produced much smoke and stink finally had a night with good
        transparency and no wind so able to go for the fainter/more difficult
        satellites.
    
    (2) #96019 has a short period with weak flashes, visible all the time
        #96028 slight variability
        #96031 bright and steady - payload ?
        #96032 maybe slight vary
        #96060 CANYON satellite - slight variability
        #96076 Transtage - steady
        #96091 bright and steady - payload?
        #96093 bright and maybe slight variability
        #96103 CANYON stage rocket - irregular tumbling, weak flashes and
               period about 30 seconds VERY approximately.Invisible between
               flashes
        #96127 bright with maybe long term slight variability-payload?
    
    (3) DEL4DEM #28500 -trail not well defined as object is variable.First
        measure should be the better of the two given as faded out at end of
        second trail
    
    Cheers
    Greg
