Comments: Imaged Saturn August 22nd 2019 in good seeing. Have very good depth of detail. The most prominent features by wavelength are; 685nm-Pass IR very well resolves the vertices of the North Polar hexagon along with the North Polar vortex. Considerable structure is seen within the NPR with a most prominent white spot at approx Lat+73.3 L3 2.5 there appear to be some dark features at approx Lat+32 L3 31.7 this maybe multiple dark spots in close proximity to one another. There remain two dark, parallel linear features within the EZ, these have been visible for some time. The R channel data is exceptional with a smorgasbord of well resolved detail to great depth across the field. The evolving changes to the morphology of the NPR are well seen and reveal a linear structure of quite thin dark and bright bands. Prominent bright spots are resolved at approx Lat+35.4 L3 332.9 and Lat+29.8 L3 17.5. A very conspicuous thin bright band is resolved in the NEB very near the border with the EZ. There are multiple features seen within the EZ, best seen in the R channel animation as are the prominent tin dark parallel linear features within the EZ. The RGB data is also exceptional, regarding the same depth of resolved detail seen in the R channel does not diminish with the addition of the G & B data. The NPR structure is very well seen and the animation of the RGB data shows many resolved features across the field.
