    NOTES:
    ----------
    
    (1) Classified high altitudes identified. Still have many (!) strays to
        report but in a few cases confusion exists due to several satellites
        close together. Also about 20 "unknowns" found for which nothing
        matches in HEAVENSAT - the majority will be defects - ie cosmic ray
        strikes, dead pixels etc but will have to examine the images closely
        to determine whether real or not.
    
    (2) Used the setup in 1 bin mode which means enormous image files - 16
        or 32 Mbytes ( dont know why sometimes 32 Mbytes as it should be 16
        Mbytes but looks "normal" and processes okay.)   Since images are
        3326 x 2504 pixels they have to be examined a bit at a time since
        cant display entire image in full resolution.
    
    (3) All in all something like 800 positions on about 150 satellites -
        took about 6 hours to mark "satellite-like objects" in the images and
        APEX took about 40 minutes to process 99% of them.
    
    (4) New 8-inch f/4 reflector - doesnt look like arriving today and since
        not many people work on saturdays Ill only get it monday. The mirror
        is spherical - thats why cheap - but have organised with a local
        amateur telescope maker (ATM) to parabolize it if image quality not
        good enough.
    
        I swopped him some "surplus junk" for a 12" f/4 parabolic reflector
        on a dobsonian mount but this will only be delivered in a few weeks
        time.... Not exactly sure what Im going to do with it as FOV will
        only be about 1 degree with the CCD camera and I will have to build
        some encoding system to get adequate position resolution for remote
        use....  Will keep me out of trouble for some time!
    
    Cheers
    Greg
