Joan, motion on the .gif will be determined by the image scale. I'm pretty sure Patrick images at a much longer focal length than the astrograph Tombaugh used. I could be wrong, but I think Tombaugh was using a wide-field camera to cover as much area as possible with each exposure. If Patrick images at the same scale that he takes his supernovae search frames, motion should be noticeable in only a couple of days.

That's a very good idea. Too bad it wasn't mentioned sooner, a .gif of a day or two might not show much. It's my understanding that Tombaugh found Pluto fairly quickly, once he started the work. One of the reasons he was chosen was because he had "sharp eyes." Pluto had been found much early, but no one caught the movement before 1930.
