Seeing conditions varied significantly during the session,with a definite downward trend towards sunrise.
I did get a short spell of a few minutes of better seeing where I managed a good R,and half decent G and B,for the RGB.
The IR bore the brunt of the degenerating conditions and also dew formation.
I note that John Rogers has recently made mention of the wave formation in the NEBn following the WSZ,and as it happened I was looking directly down on it.
The fine dark line extending almost all the way across the SEB southern region is also quite striking.

Jupiter,Io & Ganymede on May 18th,2020,under correct conditions but
low in the sky. Ganymede the biggest satellite shows some details,and
we can see the great red spot rising,and an intersting dark feature at
meridian in the south part of the north equatorial band.
