SPX350 F29.5, PGRFlea3, Baader RGB filters, Astronomik IR742. 140033hrs UT.
Seeing was forecast to be good and sky clear but high mist and scudding cloud dominated giving me only one opportunity to get Jupiter over an hour past the meridian at 37 degrees alt and it turned out well. Cloud then came in stopping my Mars ambitions.
I took 80 sec subs and tried the derotate avi in WinJupos before stacking but it produced a negative image which VirtualDub fixed. The derotated video results were better than the straight avi's when assembled in WJ.
The derotated detail had better contrast with less noise and edge and pole detail seemed better. This derot processing takes some time.
My planetary processing skills are a little rusty.

Thanks, John.
