I'm not fully sure what you mean by shake... probably because I didn't explain what I was using very well.

The camera itself wasn't shaking as it was held in place with my bracket. It is a video camera, and I actually filmed the shown area as it travelled across my field of view, then stacked it in Registax. I wasn't in contact with the scope at all during the time it was filming.

Westsky- would your idea about resting the scope against something be good for stopping wind shake? Although I havn't noticed a lot of wind at my place since I've started astronomy, there could be the odd breeze I havn't picked up. Would something keeping the OTA stable be a good idea? Or would it just be too hard to move the OTA to realign?

67Champ - I used my 32mm eyepiece (with the camera held to the eyepiece) with my f5 Dob. That makes it about 39X or so power I believe. Also, I did use the camera zoom (the digital zoom) to after 10X, but probably just before 20X (maybe 16 or 17?). I have been able to use the camera's digital zoom now ALOT more than I was a few nights ago, as I found the manual focus button. That way, the only focusing I need to do is with the telescope focuser, and the image doesn't randomly blur in and out. Here is an example of size comparison with the zoom I am now able to use. My display picture is the size I could use a few days ago. With manual zoom, I can now get Saturn to be larger (See attched image). The larger image is only a test (and is therefore extremly crappy), and I am sure I could get it looking much better with another night of Saturn.

EDIT: Forgot to mention (this relates to 1ponders post), my actual telescope doesn't have any balance problems. I thought it would with the added wait of camera bracket + camera, but it still balances beautifully. The only time when it doesn't balance is when I am pointing the scope at something quite low on the horizon, and seeing as I pretty much only really have overhead + a bit of sky visible due to my family living in a small forest of type, it doesn't bother too much.
