Hi Roger,
I think you have done well with a tough candidate! Perhaps you might pick a target next that has a lot of colour, isn't so small, and is brighter! That might give you a better feel for CCDStack when you are not fighting so many difficulties. I'm a big fan of CCDStack. It made a huge difference to me when someone kindly suggested I give it a try. In case it wasn't already mentioned, the tutorials of Adam Block - one each for CCDStack and Photoshop - are outstanding. If you have any questions about CCDStack I can try to help you with what I do know.
Peter
