ようやく少しマシな気流となりました。
SEDらしきものがSEBnの明部の前端にある気がします。
BAはSTBの途切れとしか眼視では分かりませんが、画像では暖色系になっています。
STrZのリング暗班も健在です

木星が昇るのが早くなったので、夕食前に1枚取り、久しぶりに合計3枚取りました。
I=180°付近でSEBnが少し淡くなっています。SEDの本陣と思われます。
BAは相変わらずですが、ボンヤリと明るく見えます。
STrZの大リングは、BAよりもだいぶ後方に行きました

大寒波で乱高下のある厳しいシーイングでした。

Clear skies but with frequent passing clouds that partially compromised transparency.
I can't exactly define the seeing,but details were visible on the screen.
The shadow of the satellite Io was clear,but Jupiter looked like a bubble. Perhaps the jet streams?
The GMR is just setting on the east side.
Anyway,this time I tried a new setup. I removed the ADC and the 2.25X Baader Barlow and used the 2X Televue Barlow.
I'm not displeased with the result at all.

Today I had the pleasure of meeting Dale Hollenbaugh who was visiting Curacao. Dale brought 2 planetary cameras and we made a small comparison.
For me it was a great opportunity to test the camera's in combination with my gear: a Celestron 14" EdgeHD with a Baader 1.3xBarlow.
The cameras that we tested are the ZWO ASI585MC (pixel size 2.9 μm),
ZWO ASI676MC (pixel size 2.0 μm) and the PlayerOne Neptune-664C ((pixel size 2.9μm). The last one is my own camera.
Here are the results of stacking 50% of 3.000 frames that were captured in a 30-second SER-file.
Only the wavelets in Registax are applied and I increased the saturation. No de-rotation,no sharpening and no de-noising.
Due to the smaller pixel size of the ASI676MC camera I removed the 1.3xBarlow lense.
Which has the advantage that you captured more light and with the same 80% histogram
I could almost lowered the gain by 50% in comparison with the other cameras.
The speed of all 3 cameras is more a less the same. In my configuration I could capture 100 FPS.
The ASI585 looked very nice in the live view but the result lacks details.
My conclusion is that I am happy and stay with my current camera the Neptune-664C.
The ASI676MC camera looked very promising and has the advantage of the smaller pixel-size and enables me to shoot at prime focal length.
The mono version of this camera is probably very interesting to use with the Methane filter.
Of course this test is not final and is maybe not as objective as you hope.
The seeing is of course changing and improving in the night,but besides that is was a great opportunity to test with my own gear.
The sweet spot for me seems to be the combination of the Neptune-664C camera,the 1.3xBarlow with the C14.
