Just as a side note for anyone who isn't sure, the last blink images that I posted are Hubble data, the field is tiny compared to what I've been able to capture, even on a tight crop.

I got my original field wrong, only by a tiny amount but I spotted the wrong moving star. I also may have misread the DR2 data for the parallax measurement but I'm not sure. It wouldn't be unusual to spot a small star (brown dwarf) between us and 47 Tuc as it is estimated that there is a bucket load of them out there... Yes, bucket load is a scientific amount!
As for having a parallax of 1.1 arc seconds, that would potentially make it within the Oort Cloud which I suppose could be a possibility considering it is Hubble tanking the images.
