A period of reasonable to good seeing last night combined with a break in seemingly endless cloud,gave me opportunity to grab some shots of Jupiter last night and into the morning.
Here's a capture built from using single derotated RGB's.

Attached is the stack of 9 derotated images of Jupiter prepared from nine 60 second videos taken between 0547 and 0554 UT on November 30,2012.
Seeing was below average,around 4/10.
Videos were taken with Firecapture 2.2 and a Flea3 color camera coupled to the 7.25" f/14 Schupman medial with a 3x Barlow lens giving an effective focal ratio of f/48.5.
Videos were preprocessed in PIPP followed by alignment and stacking of the best 1200 frames out of 1900 in Registax6.
The nine images obtained from this process were derotated and stacked in WinJUPOS,and further sharpened with Registax6.

This morning saw unusually good seeing for this location.
The diffraction pattern of Aldrebaran which I use to collimate with on screen looked almost perfect.
Unfortunately there was cloud as Jupiter culminated at midnight,and it took a long time to move off.
The beautiful filigree patterns in the cirrus illuminated by the moonlight,with a rainbow halo around the Moon,
showed the stability of the high atmosphere.
At 1am the cirrus patterns disappeared and the entire sky fugged over with a mist,but I kept monitoring Jupiter,
and it cleared at 01:15 with seeing still good.
Here is oval BA rising and WS-Z near the centre of the disk. (Thanks John for the labelled map!)

We had fair seeing and moderate transparency last night for these images of Jupiter,
showing the same view of the GRS I had last week.

Finally some fine seeing after a long period of really bad airmasses. Data are in the image.
