Thnx & Certainly do Greg, I always crop off some but here is pixel crop from the whole single frame, top left corner..
Hope gives an idea of corners I get - not too shabby all considering the width of view.
I do find these Art Lens's are much better at controlling coma and particularly color fringing than the Canons range, by a long shot actually, i will never buy another Canon lens for astro unless they correct the issues..
