On the same night, I took a quick shot of comet ISON, near Mars. It turns out that during that time, the second-largest largest known near-Earth object (NEO), asteroid Eros, was racing by as well. In the 3 frames I took, you could see them both moving.
My final result here is of the best from from the three (so is noisy)...a single 4min exposure and in mono (as this was through a single filter, Lum). I have annotated the result.
