When taking a picture using F10, the picture file has a
noticeable problem with the upper left quadrant
background star field: it shines through the foreground
object(s), and it's brighter than the remaining background
stars in the picture. This problem cannot be detected on
the monitor screen, it only shows up when looking at the
photo file in a photo editor. This problem is severe
enough that it ruins the 'believability' of the picture.
