hi ken

I assume you sent the jupiter image thru registax?
the colours need aligning, as you can se teh redchannel hangs over the left hand side of the planet. this might help somewhat

also either the seeing was particularly bad or your focus might not have been spot on.
(wish i had bought my lappy with me, i could have fiddled with it)
as for the other 2, how long was the exposure? the stars look burnt (i know nothing of widefield processing tho).
hope this helps a bit... one newbie to another
