Two images (one as insert) showing movement in 24hrs.  Distance 50AU.  The ephemeris magnitude is 17. 
I have had this plotted on Skymap for a while, so with the Moon absent I imaged the area over two evenings and found it easy to detect.  The camera is IMX174 (global shutter) 12/16bit,  and the gain was set at 300 (range 10-480)
