    hi Ralfn,
    
    looks impressive at first sight. However, as I told you before,
    for most of your previous shots of ISS there are things that I
    can't explain or relate to existing details, especially all the
    irregularities and bright dots that appear here and there.
    For example, there is no reason why the left edge of the
    payload bay would not look straight and even.
    Almost 20 years of imaging of all celestial objects
    make me do think to noise, perhaps amplified or
    transformed by processing into something that
    look like details.
    
    So, to decide, I would really like to:
    - know if this is one shot or a combination of several ones
    - see the raw image(s)
    - know the exact processing that has been applied:
    sharpening/smoothing/enlargement etc.
    
    thank you Ralf!
