    NOTES:
    -----------
    (1) Testing out different lenses. 80mm f/2 lens - too fast for my sky,
    could only do short exposures. Focus too soft - unsuitable for tracking.
    50mm f/1.8 lens - apart from small image scale does not perform too
    badly. 80mm lens used with Meade DSI Pro II CCD camera and 50mm lens used
    with MINTRON video camera. Stopped by cloud eventually.
    
    (2) All measured manually - too lazy to set up APEX for a one time only 
    application.
    
    Cheers
    Greg
