I had variable seeing this morning during my Saturn session.
Dione was in transit near the south polar region,and I have included a cropped section of the best R capture showing the transit.
Dione was just leaving the transit in the IR.
Unfortunately the G and B were poor,giving a low res RGB.

Seeing was 7-8/10. Transparency 3/5.

I already sent my image of Jupiter with a Shadow Transit of Io exiting the planet.
Just finished processing the Saturn image from that morning. To my surprise a shadow transit of the moon Tethys was occurring! This is my first observation of a shadow transit on Saturn! The seeing was very good and the transparency was above average with some haze. I derotated six one-minute videos. See the results.
I have a question regarding the LD compensation in WinJupos. What values should I use for LD value and LD angle?
I watched Chris Go's excellent series of videos on YouTube and Chris initially recommended a value of 0.65 and 0.65. In a later video he changed the values to 0.90 and 0.90. I find I get artifacts around the edges of the planet using either of these values. I left the LD compensation box unchecked in producing this image. Leaving the LD compensation unchecked produced the best results. Any comments/suggestions?
What number should I use for the LD value and LD angle? Are there different values for different planets. What is your experience? Please advise. Look forward to hearing from everyone.

このところずっと梅雨の雲間を縫っての撮影で、まとまったセット数が確保できないので、デローテーションができません。全部単発です。
そのために、日によって随分と解像力・像の荒れかたに差があります。早く梅雨明けしてくれませんかね。
