Looks like a moon or LP gradient to me... longer exposures will really show up gradients... especailly if theres any moisture in the air...

A Quick look at the sky from last night puts luna in the right sort of place to cause this type of gradient...

Yeah.. that will be the moon's fault. It was so bright last night that even Eta Cygni (η Cyg) was barely visible.
