    the debris theory sounds very plausible to me Markus. If you look at the
    high res IC1795 shot on my website, you see that the center track is rather
    wide and diffuse as if there is a trash line there with it. That would be
    consistent with your theory about there being debris.
    I find it hard to believe this is atmospheric. I had thought briefly that it
    may be an internal reflection problem, but I'd expect other artifacts to
    show up with bright stars and so on if that were the case. I just don't see
    the artifacts.
    So what is the explanation for Schmidling's discontinuity? Here is what he
    said when asked about the date/time and observing location.
    "The date stamp on the fits says 1/5/02 22:09 local time (CST). My notes say
    6. The site is near Rockford Illinios."
    He was shooting M1, The Crab Nebula. Any chance it was a satellite?
