Condition was close to perfect today.  Seeing was great but transparency was a bit variable.

This might be the "boring" side of Jupiter but there are a lot of interesting activity.
Note the wavy band on the northern edge of the NTB.
White Spot Z on the NEBn is very prominent and this spot seem to be brightening on the methane band.
Note the dark red barges on the NEB.  The activity on the STB also looks interesting.

Here’s a set in reasonable conditions this morning.
The GRS is setting and the NEB remains quiet with dark barges,with similar colouration to the EZn,
while the SEB remains less red and more indistinct.
Some decent details in the methane,but still a ways to go to the best resolution.
The small white spot on the N(N?)TB is resolved as pale in the methane band.
Thin clouds halted the second RGB run,which is only a couple of frames in each band.
Clear skies,

A good image of the GRS. Some bright spots are to the left and north of the GRS.
I can see about three white ovals on NEBn. Two ovals are on SSTB. Note about three barges on NTBn.
A dark segment on NNTB and some spots on NTZ.
I thoght I could have a better image result because a little before to start imaging I observed the planet with my TMB 5mm eyepiece
and I could resolve the two parts of SEB pretty well and in most of the time,
even the moons were very tiny rounded with little dispersion,but I guess it would have been better near the opposition.

An rgb image & the individual filter components as well as a small red-filter animation showing
how the seeing conditions depreciated markedly during the imaging session.
Also included is a 2-frame rgb animation.

Imaged Jupiter May 17th in good seeing, 
very fine small scale detail was clearly visible in the live feed from the camera for the entire session.
Many tiny dark spots and small bright ovals are resolved in the NPR. 
The Northern edge Of the NTB is dominated by an incredibly delicate scallop pattern. 
Two prominent red barges are resolved in the NEB along with several large diffuse bright oval 
features most apparent in G, RGB and B data. 
The boundary between the EZ and NEB is dominated by a thin red linear feature. 
The EZ has an orange hue to it and there is significant very fine small scale detail within the SEB 
which is particularly well seen in the 685nm IR and R data. 
Two small white ovals are rotating in from the F limb in the SSTeB and very fine detail is resolved within the SPR.
