Transparency was low today because of clouds and dew. Fortunately,derotation saved the day... Seeing was excellent.
On the first image,the two NEB white ovals seem go be getting close to each other.
Will there be another merger soon? It is interesting that in 1 hour,the NEB shows a lot of contrast!
During the first image,the NEB is very busy with outbreaks and rifts.
While the region closer to the GRS looks quiet!
The NTBn looks interesting with small ovals surrounded by dark materials.
Oval BA is very dark. The dark cyclonic oval following BA is very prominent.
In between the two images,I received the news that great British Astronomer,Sir Patrick Moore passed away.
I would like to dedicate this imaging session in his memory.
I could never forget when he showed me his journal of visual Jupiter observations,when I visited him at his home in Selsey.
His down to earth humor and patience to explain complex scientific details in layman's terms have drawn millions into Astronomy and the sciences.
Rest in Peace Sir Pat. I'm sure your view of the heavens are much better now...

In this presentation RGB is at acquisition's size and color stamps are 75% sized.
Next sequence shows an "L" exploitable for an L-RGB picture; differences with RGB are real: more contrast and details!

I have been sorry to learn about the death of Patrick Moore... it
reminds me when we lose Audouin Dolfus a few years ago :(
During a brief hole in the cloud cover on the same day I have been able
to take one LRGB image.

I have a monochrome Flea 3 camera now, but haven't quite worked out the optimum settings for it.
Here are some early results.
I think the gain was too high, resulting in a ringing effect. Still, something useful might be got from these images.
The RGB is made from an RGBRGB sequence of 40s videos at 60fps. Io and its shadow are smeared by their orbital movement.
Also provided is a single 40s red.
