Good effort. To bring out the detail you need a much shorter exposure.
One trick you could try is to take video of jupiter, and then use Registax (free software -
http://www.astronomie.be/registax/) to combine all of the video frames into a final image. Registax can be set to reject any individual video frames where the image has been blurred by camera wobbles or from turbulence in the atmosphere so that only the best frames are kept - these are the ones that are then used to stack for the final image.
The camera I use for planetary (a QHY5) takes video. I usually have it set at about 50 fps. I see that your Canon IXUS105 takes video at 30fps, so i would give that a go using short videos of about 30-60secs each. Good luck!
(ps - have you considered using a digicam bracket rather than the old-stickytape-to-the-eyepiece trick. Will be more reliable for focus and camera alignment, and you wont be putting stress on the lens motor. You can get them from Andrews Communication for $39. Follow the "Long Perng" link from
here and then scroll down the page. Delivery would probably only be $10-15. Something to save up for maybe...
