Its not the telescope or camera, its your processing skills (Sorry).
You have a very good camera and an excellent scope.
There are some help links here
http://web.aanet.com.au/gama/help.html which is on my help web page. It should take you up a notch in skills i hope.
As for the Jupiter over exposure, as others suggested, you need to stop down your scope (Block more light) to get the image better.
Good luck.
