UA/ANU Siding Spring Survey Observes EPOXI's Spacecraft
Caption: Astronomer Robert McNaught of the Siding Spring Observatory recovered (successfully imaged) EPOXI's spacecraft on 29 Dec 2008. The five 10-second exposures were tracked on the motion of the spacecraft resulting in the star streaks. There is a 16 second gap between exposures. Mr. McNaught provides more details below.

These long exposures were just for publicity. All reported astrometry was from 1 sec exposures, tracked on EPOXI's motion, with the images generally very faint. For the record, the pipeline magnitudes for these 10 sec exposures are 17.8V, 17.5V, 17.3V, 16.9V and 17.5V.
I failed to see EPOXI on images taken around 10:20UT and 16:05UT, either on single or stacked 1 sec exposures. At the end of the night, EPOXI was in front of the Large Magellanic Cloud, so I didn't attempt it then, difficult as it was in open skies.
