南中前はまずまずのシーイングでした。

Seeing was variable this evening.
Saturn's rings are still bright but not as bright as around opposition.
The polar hexagon and dark polar spot are distinct.

I was expecting jetstream interference last night,but conditions turned out fairly well.
I don't know if I am imagining things(not impossible!),
but I again was able to see the rotation of a dark area in the equatorial zone(more noticeable in red channel) whilst processing.
I estimate it at latitude -2 deg and system I long 345 and is approaching the CM in the RGB image.
In the IR image the equatorial dark spot is on the CM and just about detectable at this wavelength.
