Comments: Imaged Saturn August 5th targeting a transit of the –55 long lived red spot. The spot was at the CM very early for me with Saturn quite low however I was able to resolve it. As it happened Tethys was also in transit but near the P limb. My data from this session covers 3 hr 50 min of Saturn rotation so a significant proportion of it’s circumference.
Detail resolved in these data.
A faint white oval at approx Lat+37.1 L3 147.7 resolved in IR, R and RGB.
A bright slightly elongated spot just below the ring shadow at approx Lat-18.9 L1 77 resolved in IR.
Tethys in transit at approx Lat-42.6 L3 59.2 resolved in IR and R.
Long lived red spot approx Lat-56.2 L3 89.3 resolved in IR.
