10cmでの土星です。透明度が悪く、30msだとゲインを大きくすることになり、45msでも撮ってみました。
枚数は7割位に減りますが、45msの方がよく写ったように思います。C環も出たし、本体の縞も写るとは、デジタルの威力ですね。

Finally a usable image where you see a lot of detail,yet with poor resolution in the rings and without a prominent C ring.
Using the conversion tool of the Irfan software I left what it would look like if I had made an RGB capture.

Imaged Saturn August 1st in good seeing,have very good data across all channels. The most prominent features are two largish bright spots well within the NPR with one of them hard up against the edge of the North Polar Hexagon. I measure these spots to be at approx Lat+77.2 L3 328.8 and Lat+72.2 L3 319.2. The vertices of the Hexagon are very well defines as is the North Polar Vortex. I have frequently resolved a ripple on the Northern edge of the EZ impinging into the NEB,I note in these data two well resolved ripples on the edge of the EZ and I measure them to be at approx Lat+15.8 L1 309.8 and Lat+ 15.6 L1 333.2. I also note a parallel pair of linear features within the EZ and a very thin bright linear feature in the NEB,very close to the edge of the EZ particularly well resolved in the R channel data.
