    Notes:
    --------
    
    (1) This concludes report for 11th July. I will not be using this
    particular lens again for serious satellite work as limiting magnitude
    is not faint enough and useless for geostationary work.
    
    (2) the next lens to be tested is a French TV camera telephoto lens
    operating with a focal length of 15mm to 150mm at f/2.8. It will be
    relatively easy to motorize the focus and focal length adjustment.
    Image quality looks very good but first impressions are it does not
    go as faint as my 145mm lens. Examination of the optical elements shows
    signs of fungal growth and numerous small scratches which will only
    serve to scatter light and reduce performance - this is probably why
    the lens was scraped and I got it for nothing. Beggars cant be
    choosers:-))
    
    Cheers
    Greg
