    NOTES:
    ---------
    (1) Looks like my cloudy season is starting rather early. There was
        virtually no summer and now cloud every night often with rain
        - rather unusual for this part of the world.
    (2) Main purpose was to get USA 227 and USA 235 which I just got before
        the rain came down. Managed to get everything inside before any
        damage done - the tracking set-up has 230V AC and +15V DC exposed to
        to weather so rain or moisture not welcome !
    (3) Some magnitudes may be a little wonky due to photographing through
        drifting cloud.
    
    Cheers
    Greg
