Conditions were just reasonable after an afternoon rain storm that cleared the air pollution.
What has affected seeing were both strong jetstream of 50 m/s and ground level humidity about 93%.
Temperature of 20 degrees Celsius was nice for a winter night.
There were some wind gusts,around 8 m/s,that shook my C8 Evolution mount a bit.
Hopefully Saturn is very forgiving and a good final image was produced.

The seeing was bad.

Imaged Saturn August 14th,considerable amounts of cloud were moving through but the gaps big enough for my data runs provided good seeing.
The North polar vortex and vertices of the hexagon are very well resolved in the 685nm IR data.
The IR data also resolves some of the concentric structure within the North polar collar and the IR animation nicely resolves the brightest segment of that structure rotating in from the F limb.
The R and RGB data resolves the dark and bright fast moving spots just inside the polar collar which I measure as follows; dark spot at approx Lat+63.1 L3 224.2,bright spot at approx Lat+62.1 L3 232.2.
All wavelengths resolve the largest amplitude ripple in the EZ impinging into the NEB.
