    Observations 18 JUNE 2011
    -------------------------------
    
    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.
    
    Meade DSI Pro II Monochrome CCD camera without filters.
    using integration times of 05 sec min to 30 seconds maximum
    depending on brightness of sky in particular area.No image
    processing done but dark field applied.
    Used with 102mm aperture f/2.56 refractor ,field of view 84 x 63
    arc minutes. 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 checked against GPS signal.
    Images processed and automatically reduced using APEX.

    NOTES:
    ==========
    (1) A rare reasonably clear session for my rainy season. However
        transparency poor due to light high mist and very high humidity.
        Seeing poor and unstable. Session eventually terminated by cloud and
        rain.
    
    (2) Main purpose was to reacquire VORTEX 6 after its orbit change
        recently. Precomputed where it should be if it followed previous
        trend when doing an orbit change and found it about 3 degrees out
        in azimuth from the predicted position.
    
    (3) Remainder of satellites uneventful but failed to see a few due to
        them being too faint for the conditions.
    
    (4) Video recorder not used - remote controller now very ineffective
        despite cleaning the rubber pad (which has been done several times
        already so not much conductive material left on the the  contacts)
        so need to go and buy  some conductive paint and paint the contacts
        so as to get proper contact again - trivial matter - just got to make
        the trip to my electronics supplier to purchase the paint- quite
        expensive but since remote controller is now obsolete and unobtainable
        one has no choice.
    
    Cheers
