Comments: Imaged Saturn July 16th targeting a transit of the Lat-55 long lived bright spot. Seeing was variable and initially I was worried that I would not be able to stack enough frames to eek out the spot but the data proved just good enough.
Have only 685nm IR and CH4 data, R G and B were a waste of time.
These data cover 2 hr 28 min of Saturn rotation.
The long lived bright spot is resolved at approx Lat-55.5 L3 153.9.
A v-long thin bright feature mid SEB is seen centered at approx Lat-33.2 extending from L3 161.2 back to L3 199. Previously when I have captured this feature in good seeing it has resolved into multiple bright spots v-close together.
