Comments: Imaged Saturn September 22nd in good seeing covering 1 hr 41 min’s of Saturn rotation. Have very good data at all wavelengths with best RGB’s I have produced this apparition. The 685nm IR data resolves two bright spots leading a dark spot on the edge of the NPR with the dark spot at approx Lat+65.3 L3 44 and bright spots at approx Lat++63.9 L3 33.8 & Lat+64.2 L3 22.5. The IR data also resolves a prominent mid-latitude bright spot at approx Lat+29.4 l3 60.5 The RGB data resolves a dark spot leading a bright spot on the edge of the NPR but they are at different co-ordinates to the features resolved in the IR. The dark spot is at approx Lat+64.8 L3 24.7 with a bright spot at Lat+65 L3 32.7 The RGB data resolves one of the ripples on the Southern edge of the NNTeB at approx Lat+47.5 L3 21.9 and mid-latitude bright spots are well resolved at approx Lat+35.9 L3 21.4, Lat+29.8 L3 60.3 and Lat+29 L3 9.4 a bright EZ plume is also resolved at approx Lat+10.7 L1 20.1. The R and G channel data resolved all of the features mentioned above in the RGB other than the NNTeB ripple which was not as well defined, I think it took the combination of the R, G and B to do the trick. The CH4 data resolves structure within the EZ including a formation of bright spots along the edge of the ring shadow, have measured and marked on of the spots at approx Lat-0.9 L1 66.6.
