Thanks Harry.  I looked through the Control Point Table, looking for large
distances.  There were a few that were around 40-50.  They looked very good
to me so I don't understand why the distances are larger than the others.
I deleted a few but since they looked ok, I left the others in.  Not sure
what I'm looking for.

Also, I did try what I suggested a bit earlier.  I put the same image on
both sides and was able to add some horizontal line control points twice to
the same image.  Don't know yet whether or not that will cause the horizon
to be straighter.  Will report soon.
