Comments: Imaged Saturn July 31st 2019 in good seeing targeting the 2010 GWS AV, have very good data. The 685nm-Pass IR data best resolves the GWS AV while it also is seen in the R channel data. It is difficult to see this feature in RGB but it is there albeit very faintly. The most prominent detail resolved by wavelength from this session; The IR data nicely resolves the GWS AV it is a dark spot seemingly embedded in a faint brighter annulus. I measure it to be at approx Lat+42.8 L3 181 the IR data also resolves the ripple on the Northern edge of the EZ at approx Lat+16.2 L1 298.3 the IR also resolves a linear feature within the EZ; The R channel data also resolves the GWS AV along with a compact dark spot at approx Lat+60.4 L3 208.9 a bright spot is resolved at approx Lat+28.7 L3 171.2 the R data also resolves a thin bright linear feature in the NEB very close to the edge of the EZ. The RGB data also resolves the bright spot at Lat+28.7. The Ch4 data also resolves the linear feature within the EZ. All data well resolves the North polar hexagon and Polar vortex with IR and R data also resolving the morphology of the NPR. I have animations of IR, R and RGB data sets which particularly well show the rotation of the polar hex vertices.
