    Notes:
    -----------
    (1) The pathetic weather conditions persist - is it ever going to clear
    up again properly ?. Both nights dodging clouds before wiped out.
    
    (2) Purpose was to evaluate the 6 inch f/2.7 reflector for routine
    tracking. Looks promising but conditions so far too poor to form a real
    opinion, the last nights being plagued by bright moon, clouds, rather poor
    focus ( focus seems to change depending on telescope position so will have
    to install remote focus control.), and inability of camera to integrate 
    properly
    with all the cloud passing over.
    
    Cheers
