Nice one Mark
I think the Swan is a fairly subtle visual illusion - you've got way too much firepower there for it to come through. Maybe switch over to a 15" dob for the visual effect!
(I could see it in dobs at the South Pacific SP ok)
I'm probably wrong, but I see it as per below.
This link with a much less sensitive pic shows it a bit more too I think.....
