Subject: Saturn storm animation!

I grabbed some data on Saturday morning but seeing was only good and not excellent.  To make the best of the early hour I made a two frame animation with data taken about half an hour apart.  The storm in that Northern hemisphere band moves with amazing speed to the point where I have to reevaluate my imaging parameters.  In the past I'd take my time collecting data between RGB colours since the bands are relatively stable and featureless (unlike Jupiter).  I take about 3 minutes to collect 2000 frames at 15 fps for each colour but I think I now have to limit my data collection to about 1 minute per colour.

Even with the 12" mirror at f/15 Saturn remains a fairly faint target when imaged through colour filters at 15 fps.
