Asteroid 2004 BL86

On January 26, 2015, the Putman Mountain Observatory telescope was pointed to a near earth object (referred to as an NEO designated 2004 BL86) that passed within 750,000 miles from Earth.  This asteroid was photographed in a timed video sequence of approximately 50 separate images.  Each image in the video sequence is a five second exposure.  The telescope was tracking the background stars, and therefore, the stars appear fixed with the asteroid moving in front of the background stars.
