雲が多い天気でしたが、シーイング、透明度ともに良好で晴れ間に撮像できました。

セブ島は台風の影響で星が見えない夜が続いています。やっと少し晴れ、衝を過ぎた土星画像が得られました。
薄雲空の悪条件ですが土星環の本体の影がほとんど見えません。悪気流、イメージは悪いけど45㎝反射の光軸は良く合ってきました。

シーイングがかなり悪い状態でしたが、しばらく待つと少し安定したので撮影しました。

Only IR 742nm data was OK due to the poor seeing.
I've stacked the RGB with the IR (70 with 30%) to show both some detail and also some color.
A large spot in the South is seen,as are many details around the equator.
The animation shows a lot of details rotating with the planet.
Here is a partial map of Saturn compiled from observations on September 21,22 and 23,2025. All images acquired in near IR (742nm filter). Images used for the map are also shown.
Of note are the two spots marked as O1 and O2 around the South Temperate Zone/Belt. However,note the many details in the Equatorial Zone North (marked with an arrow),some of which are visible also in RGB images. The Equatorial Zone South also presents some details,but much less obvious.
The black spot in the middle of the map is the shadow of Rhea transiting the planet on September 22. Rhea itself is the brighter spot just South of the shadow.
