With me rating the seeing during my Saturn session this morning at 4/10,I stuck with R/IR monitoring captures.
I have to admit my attention was heavily distracted during processing by the Women’s Football World Cup quarter final between Australia and France- an amazing game! Congrats to my Aussie friends and commiserations to my French friends.

久し振りに雲に邪魔されずに撮影できました。でもIRを撮影後、雲が広がり、画像処理中に雨が降り出したので
慌ててルーフを閉じました。シーイングはまずまずでしたが、湿度が高く透明度は低めでした。

良い気流で、縞模様が綺麗に出ました。北半球に白斑らしいものがあるようです。
カシニの空隙の両側が白く明るいのは、処理によるノイズの気がします。

シーイングは安定していた。表面に顕著な変化は認められなかった。
Seeing was stable. No significant surface changes were observed.

台風7号接近中にも関わらず晴れて好シーイングだったのでRGB以外のも赤外、UV、CH4でも撮影しました。

I'm back from my 2023 mission at the AstroQueyras observatory,and we have benefited from two good nights,one being incredible. Here is a selection of the best images taken from both nights. I have been observing at the T620 (F/15 Cassegrain) instead of the T500.
Anthony Wesley observed a spoke on ring B recently,and some have been caught as well here,with Ic and CH4 filters !
Many subtle details can be see on the animations. The animation technique is very powerful for Saturn,since the smallest details are often hard to confirm on a still image... Note some bright CH4 spots on the EZ,I didn't think it was possible to observe activity on that band...
The camera is used at prime focus without any barlow. Added to the altitude of the site which almost reaches 3000 meters,it makes UV imaging more easy. I am using now a quite "extreme" UV filter along with the usual Johnson U,the U340 from Asahi Spectra. I detect an evolution of the albedo of the planet with the 340 filter,where the EZ is darker,and the rest of the globe slightly brighter (this can be see on the HST images between the F395N and the F343M)
