Imaged Saturn this morning, targeting the dark spot on the edge of the storm remnant.
Captured data over a 3 hr session, the seeing was quite reasonable early then went west before stabilizing just in time to image the dark spot.
Of interest in my first data set is a quite bright, concentrated spot in the EZ. I have imaged this previously, in the same data set is a bright spot in the NEB.
Have included a R channel animation, only 3 frames over the 3 hours. The bright EZ spot can be seen close to the P limb, the bright NEB spot pops in and out approx midway between the F limb & the CM while the dark spot down on the storm remnant is in the final 2 of 3 frames and moves from the F side to the CM. The dark spot also shows up nicely in the polar projections of the R & IR data.
