Condition was very challenging today. The sky was mostly cloudy with some areas of thin clouds.
I had to image through clouds to get these images. Seeing was good but transparency was poor.
I had to capture a lot of data to compensate the poor transparency.
The GRS is well resolved in these images. Note the outbreaks on the wake of the GRS have disappeared.
There are not bright features on methane band. The "chimney" above the GRS is open again.
The NEB is very pale and faded. In methane band,note the long dark streak on the EZn/NEBs.

I made two RGB/ IR 642 nm BP runs with the GRS in transit on 22nd September.
The seeing remained very good throughout.
I increased the focal length from 10.5m to 13.5m for the 2nd run to improve the image scale
as the seeing was good enough to require that.
The resultant resolution was quite good in both cases.
I finished with a CH4 run. I made this at Prime Focus
and it is probably the best Methane Band image I have captured with the ZWO ASI 462MC.

Here is a big set of images from 22nd September,conditions started off superb,
but declined a bit towards the back end of the imaging run.
It includes my first decently sharp UV image,partly thanks to a little help from Niall.
The SEB is a delicate set of grey stripes below a darker EZ that merges with the NEBs in UV.
Some very nice clean CH4 and RGB images early in the run cover the region preceding the GRS,
covering the more recent STB outbreak.
The NNTB red spot looks huge and prominent,there is a nice chain of spots on the STB at 90deg long,
the new outbreak is nicely resolved as a small bluish streak in RGB,and has a chain of dark spots NW &SE in methane.
The GRS has a bright core in CH4 and is somewhat lozenge-shaped,sat in a large bay below the open chimney,
while there is a delicate dark curling cloud in CH4 on the EZ p. the GRS.
The area between Clyde’s Spot and DS6 is complex with a series of ripples/pale spots.
Of the NEB barges,the two f. the GRS are particularly dark.
The RGB map has an image from the 23rd to replace the poorer last image from the 22nd.
There is a series of Jupiter images taken in infrared.
There is a large sector of low altitude in the EZ (CH4/Y) and note a curious patch in the south polar hood in methane band.

Imaged Jupiter September 22nd have reasonable 685nm IR and fair RGB data.
I note the prominent v-thin dark band and formation of compact dark spots in the NNTB.
Three red barges are resolved in the NEB and the EZ is quite disturbed particularly in IR. The GRS is seen toward the F limb and the GRS chimney is wide open.
The Northern region of the SEB is significantly disturbed,quite chaotic really,particularly in IR.
The CH4 data is not great but seems to resolve a bright spot in the GRS chimney.

Hi - apologies for the late sending,here are our Jovian images for the 22nd September 2021
captured in good conditions where a wealth of fine details can be seen across the disk.
I include WinJUPOS integrations as well as a set of single capture images & a North & South Polar projection.
