20080216 Cloudy day quiet sun

Seeing 2/10, transparency 1/10, Borg 45ED II, SM40/BF10/PST, DMK31AF03. Sky condition too bad, not really suitable for imaging, but anyway:-

1312 (GMT+8), prominence only... this is easier under this kind of situation, since you can push the gain and lower the shutter to do an overexposure, it helps to cut through the cloud:-

1327 (GMT+8), stacking means averaging, so the moving cloudy could be averaged out sometimes:-

Finally a video taken to see how worse the situation is:-
