This image was intended to be an eye-catching image of a faint nebula (NGC 1714-15) and bright stars in the Large Magellanic Cloud, but as the three separate exposures continued a cloud of another kind intervened. The insulating vessel ('dewar') containing the CCD at liquid nitrogen temperatures sprung a slow leak and moisture from the air condensed on the cold window. The pattern of condensation changed quickly over part of the glass, and was different for each exposure, hence the vivid (but completely unreal) colours in the haze haloes around some of the brighter stars.
