A photographer, J. Laurent, took some photos of the Cadiz skyline in about 1850 or so.
Jose Caravaca found that the photos contain something in the sky, on two of the photos.
The "object" is reversed for each photo; that is, the thing is pointing one way in one photo and another way in a second photo.
He's asking if anyone has an opinion about the "thing" seen.
I think the "object" is a photo or lens flaw.
But your opinion is what Senor Caravaca seeks.
