If anything the seeing for the 3rd run was even better than the second. Of course Ganymede has moved further away, so I increased the effective FOV.
There is a very interesting deep red spot in the NEB. I noticed this during processing as it was so dark for the green and blue images. The Oval BA has taken an almost light yellow colour and seems to be coming out in sympathy with the Equatorial Zone.

I thought a south up orientation with no text gives a certain je ne sais quoi.
