    Observations 10 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.
    
    
    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 reducur 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.

    Notes:
    -------
    (1) Despite a full moon conditions were pretty good so I did a long
        session which meant a lot of observations. All the above were
        processed in APEX-II.  The orbit for the unknown is that given by
        APEX  (including all the decimal places!). Since its such a faint
        satellite I doubt if I will spend much effort trying to find it
        again:-))
    
    (2) Still to follow a few satellites that I will have to process
        manually. APEX can handle such satellites but I would prefer to
        do these manually as the satellites produced long trails and it
        might be expecting a bit too much of APEX to know where the
        centre of the trail is - especially if the trail is variable.
    
    (3) It still takes me quite a while to prepare the images manually so
        that they can be processed by APEX (which took 69 minutes to do
        the above - had 183 images in total - not all reported! ) but I
        am working on automating the entire process so it will simply be a
        case of getting the observation, running a small program to get
        data in the format required by APEX - will probably take the PC
        less than a minute to do this - and then run APEX proper and all
        processed under one hour.
    
    Cheers
    Greg
