シーイングはかなり良かったけど、薄雲があり透明度が低かったので、拡大率を落しました。

Dopo tanto tempo una serata di seeing accettabile,sebbene l'altezza di Giove non abbia permesso di sfruttarla a pieno.
Ho fatto una prova anche impostando la webcam a 352x288,si paga qualcosa in termini di risoluzione effettiva,ma si puo riprendere a 20 fps ed 1/20 di secondo (vista la trasparenza non ottimale 1/25 era insufficiente),ed elaborare cosi 2400 frames contro 1800.
La ripresa e stata riscalata alle dimensioni di 640x480 dopo l'elaborazione.
Allego anche una ripresa fatta con le classiche impostazioni,il confronto e interessante,e credo che la ripresa a risoluzione ridotta alla fine sia preferibile.
Saluti a tutti!

I have been enjoying all of the great images that you are sending out. I have attached my first images for the current apparition.
There are 3 sequences of R,G,B,IR,methane and a RGB composite. The first set also includes a UV frame and a false colour MIU composite. The mornign was quite hazey and I was not able to continue the UV images after the first set,as Jupiter was only 21 deg above the horizon. Seeing was good despite its altitude,5-6/10. The second series was interupted by cloud,and the time between images is irregular. The third series was the sharpest,spanning the least time and seeing had improved to 7-8/10.
I note a fairly dark material in the red spot hollow on the following side of the GRS. It is most prominent in the IR/'methane bands and shows well in the MIU false colour image.
All images through the 30cm SCT @ f26,Lu-075M CCD,Schuler filters (R,G,B,Ir,Uv) and Custom Scientific Methane (889nm,18nm FWHM). Captured with Lucam Recorder and processed with Registax 3.0.
Please let me know if you have any questions.

Here is another set of Jupiter images, these from the second night. The area p. the GRS is presented.
Some interesting details across the Planet, such as the closed circulation ahead of the GRS, and a serrated appearance to the SEBN. Overall, the dynamic activity is rather less on this hemisphere of the Planet, especially in the placid SEB.
