    NOTES:
    ---------
    
    (1) Have been experimenting trying to get fainter. Tried a 5 inch f/5
        MOONWATCH APOGEE refractor with the FLI CCD camera but not a great
        success as focus is too soft. Then tried my CELESTRON 6 inch reflector
        which is badly in need of being re aluminized - results above and,
        whilst I still have a little work to do, appears able to give me
        another magnitude penetration. I still have a CELESTRON 5 inch f/5
        reflector to try out but doubt if it will be as good as the 6 inch
        despite its poor reflection surface. I will have it re-aluminized
        in my winter cloudy season.
    
    (2) As I was experimenting I was not using the usual image capture
        software so time only good to 1 second or so.
    
    (3) Conditions very poor - about 85-90% cloud most of the time so
        trying to get in brief clearings
    
    (4) Unknown seen - easy object.  Why is that most of my recent unknowns
        all have an inclination around 40 degrees ? This one was easy and
        slow moving
    
    Cheers
    Greg
