I see what you mean Jase - looks slightly out of focus with respect to the rest of the frame.
How does one go about remedying this if the DSLR isn't 'square'?
The night this image was taken was quite breezy - I wonder if this effect may be caused by a shaky sub in the stack...but why would that effect just one corner!!??
Any ideas?
