Was the 2nd one artifically sized up? I think it's stretching it too far, given the conditions.. I agree with bird in that the first one looks sharper and nicer.
btw you can still use K3ccd and wcctrl - wcctrl just sets the camera capture settings, you can still use k3ccdtools to take the avi's.
Great shots though, that's the sort of Saturn i'll be very happy with when I get it. WIsh I had that image scale too
