You'll be surprised at what you can capture using your DSLR in movie crop mode. (it gets you in a little closer to the object, not sure if your camera will have that option)
This Jupiter was captured using my Canon 550D through my 10" Dob using a 4x Powermate.
I used the free program "Any Video Converter" to convert to avi.
It was stacked using Autostakkert.
The stacked image was then opened in Registax to apply Wavelets.
Final tiny bit of processing was done in Photoshop CS3.
I hope you have a go. Once you get the hang of it, it's awesome good fun.
