    Observations 19 MAY 2009
    -------------------------------------
    
    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) 70-200mm focal length f/2.8 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 4 inch refracor.
    Individual frames are video time stamped with GPS derived signal.
    
    (2)Meade DSI Pro II Monochrome CCD camera without filters.
    using integration times of 5 sec min to 25 seconds maximum
    depending on brightness of sky in particular area.No image
    processing done, but some done automatically in the auto reduction
    software.
    
    Used with 4 inch SKYWATCHER refractor- model 1025 - fitted with home
    made focal reducer to give an f/2.56 system. Image scale is 6.56 arc
    sec/pixel and field of view 84.8 x 63.2 arc minutes. This telescope
    replaces the 6 inch reflector used previously as image quality is
    better, has a larger field of view, less surface area so less prone to
    wind shake, and in addition is at least as sensitive, if not superior
    to the 6 inch reflector. Shows 15th magnitude stars in real time with
    reasonably good conditions.
    
    Exposure time to nearest second inserted into image FITS header
    from PC clock which is automatically checked every minute against
    GPS signal.
