透明度は悪く露出も普段の1.5倍かかりました。
ラッキーなことにL画像撮影時のみシーイングが安定してくれました。
LRGB1セットのみWinJupos LRGB De-Rotationです。

シーイングが今シーズンベストでした。今回もB画像が拡散気味で、青色のにじみが目立っています。

Attached is a drawing of Saturn made last night while waiting for the Perseids.
A number of belts present on the disk and it seemed to me that the A-Ring looked a little darker-
this may have been due to the haze which was present in the sky.

Imaged Saturn August 12th in fair to good seeing. The vertices of the North Polar Hexagon are well resolves as is the North Polar Vortex.
The 2010 GWS AV is resolved in the 685nm-Pass IR and also in the R channel data. It is very faintly visible also in RGB.
I measure it to be at approx Lat+42.8 L3 165.7. To highlight this feature I have created an animation from the IR and R data,
so covering 10.5 minutes of Saturn rotation, have indicated the AV in both data sets used in the animation.
