I haven't decided what to do about the bright lower left corner. I'm reluctant to pass it off as a gradient issue because the MCG gradient model shows no sign of it at all. On the other hand, the nearest bright stars in that vicinity are the mag 9 double pair Couteau 2938. I'm inclined to believe that we are seeing the halo caused by that pair.
