シーイングに恵まれないので，細部は明らかでない。
Seeing is not good,so details are not clear.

I started a lengthy imaging session last night,which would include some attempts on Neptune,and later Jupiter,with a check-in on Saturn. Conditions were not as good as the last few evenings,and I don’t see anything of significance to note.

Here's the full set of images from the 29th, in what turned out to be the worst seeing of that night after a good IR image. In IR, there is a bright outbreak in the northern hemisphere near the meridian, and the large outbreak in the southern hemisphere looks to be evolving a little. Also yet another spoke (5th spoke activity of the season for me since 24th August). Wandering moon Iapetus was near to Saturn, and faint moon Mimas was transiting. Mimas might actually be (barely) visible as a paler patch on the lower edge of one of the darker bands in IR (inset). No sign of its shadow though.
No major features resolved in the RGB and methane images in notably worse seeing, but the spoke in the IR image is also visible in the red filter images.
