Hi Christophe,
Thanks for the excellent Saturn images. Please see the
attached image. I composited two of your images that
are sufficiently close in time to avoid smearing caused by rotation. The
improved S/N and strong sharpen brings out the low contrast details of the
cloud belts. As you can see, the small spot remains, and
moves with the rotation of the Planet.
As was noted last apparition, these spots are very low
contrast features, and require excellent seeing to be captured clearly.
Here is the data i took from the
images:
04:04.6 UT
CM3=206.1 -40.4
04:08.8 UT
CM3=202.8 -40.0
If anything, the spot at this very preliminary stage shows a
slightly retrograding drift, but its to early to
provide accurate drifts of the feature.
Keep up the excellent work!.
Best Wishes,

Hi Eric,
Thanks for the great Saturn image. It reveals all the fine
belts and zones clearly. Also note the small dark SPC, with bright collar
remains from last apparition, and the belts generally look much the same as
before solar conjunction.
Hope you are able to shoot more soon :).
Best Wishes,
