That's pretty much correct, except to say that we are stable "enough"- we're happy to accept a few pixels of smear in order to get these unprecedented ring images. We maintain our pointing for these long exposures with frequent thruster firings (about once per second), which are sufficient to keep our targets within a ~4x4 pixel box in the LORRI images. Hence the squiggly stars. We are actually thrilled with how well this technique is working (we hadn't had much chance to test it before the flyby)- pretty good for a little spacecraft with no reaction wheels...
