    NOTES:
    =======
    (1) Apart from VORTEX 6 unable to use the meade CCD camera as cirrus too
        thick.
    
    (2) All other observations done using video until cirrus wiped me out.
    
    (3) The two SBBS 1 objects are brilliant when they come out of earths
        shadow but fade quite dramatically as they head southwards after
        culmination.
    
    Cheers
    Greg
