Update - 20130306 - Some treatments of the 1sec avi data using imageJ.

Update - 20130305 - This is probably the last effort with Panstarrs for a few days. Finally got to put the ED80mm and DMK51AS on to the comet head. I let it drift across the FOV taking 1sec images
Still to work over the set of avi's. Here is a first look at the data...
