Near-Earth Asteroid 2014 DX110 getting close: a long exposure image (4 Mar. 2014)
While waiting for it to reach the minimum distance tomorrow, at Virtual Telescope we imaged the Near-Earth Asteroid 2014 DX110 while it was showing among the clouds. After a relatively short exposure, we wanted to have a longer one, showing very well its fast motion.
Above is a 240 seconds exposure, remotely taken with the Planewave 17 robotic unit. The Paramount ME mount was tracking the apparent motion of the minor planet, so stares left a trail, while the asteroid looks as a point of light.
At the imaging time, this ~30 meters rock was at about 1.3 millions of km from the Earth. It is clear that the mount handled this fast mover very well.
