I think you misunderstand what I said. Scott's question was specific to
the moon. And my answer was limited to the question. I said keep it in
the center of the frame and don't worry until you get a really long lens.
With the moon in the center of the frame, coma shouldn't be an issue.
Its big enough and bright enough to use modest apertures and not have
star type problems, but small enough with even with 500 mm on 4/3, it
only covers the very center portion of the frame.
