I was looking to image an asteroid with the Seestar, and looking on Sky Safari let me know that (15) Eunomia would be well placed in Auriga early in the evening.
I know that the Sky Atlas doesn't have a search capability for Asteroids, but zooming in on the right area of the sky, showed a dot and label for Eunomia.
However, it was not in the same place as shown on my other App, and on taking the image, it seems that Sky Atlas has an error of just under 1/2 degrees in the position. I attach an image showing the Sky Atlas position, the Sky Safari Position, and the actual position as imaged 
How often are orbital elements updated for asteroids>
