Improve error message on failed image query

Feature request

I searched for 2010 KV8 over a 7 month period with 1 hr time steps. It crashed, likely because of too many ephemeris points, but the error message in the GUI is not informative:

Application Output:

            This terminal widget will not refresh in real-time until each full step completes.
            Please be patient after initiating a run.

Can a better error message be provided in this case? Or at least some guidance to the user on what to do next?
