Heres a finished sketch of Jupiter from a Dec 14 observation lasting 90 minutes under 4-6/10 Pickering seeing. Under these conditions then features never looked etched or sharp or crisp but reveal in a leisurely manner with a fair amount of softness. Its not BAD seeing but its work to make things out with any certainty that show without question under 7/10 or better.
Some points of note....
The South Polar region didnt cough up a single spot b ut in this seeing I dont feel too bad. Is 1" or less in detail and the seeing really was never there definitively. What DID show in place of the white spots were dark regions. These dark spots are the surrounding gases of a dark value which was strong enough to come through owing to there more generous surface area - but never a single spot. And I tried.
GRS had color unmistakebly but its buddy did not. The Monolith was seen to come and go.
The grey part of the SEB preceding the GRS has a little mottled with at least two spots darker withn it.
The spot or circular hollow appeared double which Im guessing is the seeing morphing the spot hither and yon. This was a persistent effect however and I was frankly surprised it wasnt in a CCD image of comparable CM shot the same night. Odd.
Festoons have appeared blue in good seeinjg but tonight was merely greyish. A gentle low contrast wash filled he EQ zone but only the center swath. Festoons were wonderfully smooth.
NEB had interesting dips and hollows. Indeed there was itnerior detail too but fleeting and I didnt document its exact position.
The NTB was kind of ignored, sorry.
The North Polar region had this darkening along its edge as drawn.
Magnification ceiling was 200x though forays into higher ags were tried with somewhat profitable but limited results.
I DID resolve Ios flattened diffraction appearance at 364x - sketch coming. The seeing made this possible but here the magnification truly needed here showed well just how soft the seeing was and could be. Through it all the egg shape was seen but with work - such is the challenge of 5 pickering.
Hope you like.
