Very intersting shot---a lot of physics going on there. Is it
possible to apply some x,y flipping to make the picture sky-right,
with north-up and east-left? At present north is to the right and
east is down (i.e. reverted "inside-out").
Another question: is the lens not sharp enough (or too vignetted)
to use at f/4 or f/4.7? Or maybe too much (sphero)chromatism to use
with separate filters + unfiltered and still keep it sharp? Or just
all of the above?
