Going to try and get it again tonight with more shorter, guided shots.

In the end, I did several shots (30 sg. exposure) with a DSLR over the area it was supposed to be.
Careful inspection of some images revealed it as a really dim trail on the sky, several arcminutes from its predicted position. This object is movig really fast right now.
The pictures I made are not very good because I have lots of LP and the asteroid is too dim. Anyway, an animation follows.

We loaded the daily astorb.dat from Lowell into TheSkyX Pro and it was dead on in the center of the field.
Thanks for the advice.
I tried the Minor Planet & Comet Ephemerids Service:

... with near perfect results. Somehing odd happens with the orbital elements/software I was working with. This service from MPC is good enough for me.
