Details:
First successful tracking of an asteroid as it passed close by the Earth. Old news, but finally had time to process the images and use bmp2avi.
Images taken Dec 12 2017 between 0139h MST and 0331h 30s exposures back to back using a C8 and QHY9 mono. The object was ~16 million miles away, about 5 km across and at mag 11 at the time.
