Ok - I've never actually done this before; I was approx 6 feet from a 27 inch monitor when I took this image. This is the center. It actually looks ok to me but I'm not sure.[ATTACHMENT NOT FOUND]
I remember Klaus said in his post that when doing this type of tests the lens should be slightly defocused. Am I wrong?
You tend to see it better when slightly defocused.
However, this looks alright to me. Not 100% perfect but pretty good.
As mentioned the test doesn't cover the whole scope though - there may still be edge issues.
