Thanks. No sir no filters were used. 22x60 sec exposures showed an
area which covers my aprox 1' image and would have been much larger. I
will post this as soon as I figure out or someone points out what this
is. It may be part of something larger which I do not find in the area
and is very faint but big. Thanks for your time
Mike
