Sadly bad skies today, so no data collected >:(
However, here is the latest news......
There seems to be an apparent, if somewhat tenuous, orbital motion around a central star/point. Only very rough measurements at this time, I'll do some more detailed calculations later. This point is within the circle indicated on the dss image.
Here is the latest gif animation (the last image was taken using 180 sec exposure and slightly overexposed)

I may be jumping to conclusions here. I have not yet been convinced that this is just an imaging artifact.
