Jupiter Again

I went outside again with the telescope and webcam, and I think I discovered what the problem was in photographing Jupiter.

I was able to get a much better quality image, and I really didnt do anything different.   Tonight's sky, the seeing was a good bit better, and it was much clearer, and I'm VERY happy with this image I was able to grab:
As you can see, there is a lot more detail in this image.  The equipment used was the Logitech C310 with a 2X barlow and the 70 mm Meade NG70, refitted to a polar mount.  There was no clock drive.  I used an avi of 20 frames, chose the best frames, which I think I ended up with 7 frames and stacked them with Registax.   Then with the saved image, I loaded it in Gimp 2.6.11.  There I adjusted the color balance very slightly, used unsharp mask, and adjusted the brightness and contrast very slightly.  I did VERY little processing in Gimp before I posted this image here.

So I believe the problems I was having was due to seeing.
