It's curious about the sharpness. This sort of image is certainly a good test of the lens. I took the photo at f4.5 ie wide open. This should have the worst image quality for the lens and it seems too. An enlarged image from the centre around M7 is pretty sharp but when you go to the edge there is some smearing of the stars especially in the corners of the image. This shows in the enlargment of M20. This is all only visible with a very big enlargement ie 5000 pixels wide. I will try it stopped down a bit next time and see how much better it is.
