Seeing was above average for this image. Earlier it was shockingly bad with wind but things settled down somewhat. Best seeing was early, this was taken well before culmination but Jupiter was already a respectable 63deg in elevation.

Captured with a Flea3 using FireCapture 2.1. Stacked in AS!2 with wavelets in R6. RGB image combined in WinJupos. This is a 1.2X image with Jovian south up.

Comments or questions welcome. Thanks for looking!

Glenn,

Excellent, great processing! I was out about an hour after you and the seeing was above average for me as well. What was odd was that I would get 5 seconds of steady seeing followed by 1-2 seconds of fuzz. I'm not sure if it was internal (I don't have my fans right now) or the sky. These high clouds are going to make tonight's session iffy.

Thanks all!

Paul the seeing was a little strange. Although I could sometimes see detail it was like thru a diffuser as the contrast was just not there. The red channel looked almost like all the features were near the top end of the histogram as if the gamma was set much higher than 1. Weird. I resorted to using only 15% of the frames for this second image below.

Moey, the scope was a Celestron Edge C14.

About half an hour later I captured this image. Thanks for looking!

Great job on getting the detail out in these images Glenn on what I have to agree was in strange seeing conditions. In my images the red channel came out in what was a diffuse like condition lacking much detail, Green and blue were ok but not great. Lets hope seeing gets back to normal which I hope is good seeing before opposition.

Despite the tenuous seeing both images offer a comprehensive collection of detail that I enjoyed studying for over an entire minute. Do you or does anyone use a seeing forecast other than the CSC? I've been using the one provided by the Canadian Weather Office which covers all of North America; it seems to work rather well:

Masterful work, Glenn. Best skies is all we need for opposition!

More great work, Glenn. The spiky stuff along the NTB is really interesting. And that black spot near Oval BA is really getting dark. Does anyone know if it will collide with BA?

Excellent Glenn! :applause:

Battled wind myself last night trying to eke something out "Downunder" with all the other challenges.....frustrating personally, but it is good to see so many fine images posted by others! :)

Good question. I researched my images and you can do the same and get some idea whats happening. Last year the dark spot was more of a dark ring, that has apparently consolidated and become darker and more purple/brown since then. But the distance between the spot and Oval BA has pretty much stayed constant. At least thats my interpretation. Oval BA has evolved some with a secondary annulus which makes it appear to be closer to the spot but the centers are separated by the same distance.

Wonderful Glenn! I love how bright and not washed out your images are. So much glorious detail too!

Goood stuff, Glenn!

Damian Peach posted an image of Jupiter a week or so ago showing a split in the dark spot trailing BA. Your images seem to resolve the split that ran roughly norht/south.
