Here are my first Jupiter images of the apparition. Altitude about 23 deg.
The last few in a very bright sky.
Three filters were used, R, B and a mid-IR of 807nm. Colour combinations
were made as R(synth G)B and (IR used as R)(synth G)B, the B being common to
the pairs.
Each colour a stack of 1200 frames at 10 fps. Processing in Registax and
Photoshop.
Blue barges are prominent on the S edge of NEB. There is perhaps a white
spot in the SSTB area resolved in IR 07:42.
I have left Io on, the red spot at lower left of its 3parent2 drifting
further out as time goes on.
