Seeing was rather poor but the ADC helped to stabilise the image.
The main feature was the NEB which is rather broad,the NTB seemed easier to see tonight,and the the boundary of the NPR was also darker.
A slight greenish hue present to the NTZ.

Under average conditions with Saturn at a mere 20° high,
no details visible in infrared but I could capture Titan (upper right) and Japetus (mid bottom) which is usuallt farther:

Seeing is often better for me on this planet this year than on Jupiter,despite the elevation being not so different...

Imaged Saturn July 30th in good seeing.
The 685nm IR very well resolves the North polar vortex and vertices of the hexagon along with the concentric banding structure within the North polar collar.
The 2010 GWS AV is resolved in the final two IR data sets of the session toward the F limb at approx Lat+43.2 L3 330.9.
A ripple is resolved in the evolved remnant of the 2010 GWS along the Southern edge of that thin dark band at approx Lat+47 L3 261.9 best seen in the IR but also resolved in the RGB data.
A bright spot is resolved in RGB data at approx Lat+35.2 L3 301.2. Of further interest is the Ch4 image captured during this session,
the seeing was good and the Ch4 resolved quite a bright band centrally located in the EZ.
Above this bright band and parallel to it,still within the EZ,is a quite prominent thin dark band.
