    NOTES:
    ------
    (1) Most of the above obtained by using APEX which I have now got to
        work most of the time with the wide field images. At the moment the
        success seems to have been the introduction of an infra-red blocking
        filter. This appears to give a darker background and sharper images.
        It basically kills the "bloated" appearance of stars that are reddish
        in colour. Further tests are needed to be done to determine if there
        is any loss in brightness due to introduction of the filter but
        first impressions are that this is negligible.
    
    (2) Bright unknown. When I initially observed it I thought it was MILSTAR
        1 rocket somewhat off course but when reducing the images MILSTAR 1R
        was close to the predicted position whereas the much brighter unknown
        was nowhere near anything that could be the candidate. Maybe its
        Marco's unknown ?
    
    (3) Ive had enough of satellites for today - processing wide field
        images is a real pain, even with using APEX!
    
    Cheers
