You know Al, I was looking at this this morning, I also thought this, then I blew the image up and put my reading glasses on and they looked round again. I was going to go to the optometrist to get checked out for astigmatism. I've been thinking I've been a bit astigmatic for a little while now, old tired eyes, makes it hard to judge when things are right, particularly when focusing. If they are out of round it'll be a registration problem.

Can anyone confirm that the stars are elongated up and down in the image? Preferably someone with good vision.

Cheers
Stuart
