Four stacked 60-second images taken over the course of 80 minutes on 2001 December 22 from my driveway inside the D.C. beltway capture two asteroids cruising through the constellation of Perseus. Asteroid 973 Aralia (right side of image) is about magnitude 14.4, while asteroid 1677 Tycho Brahe (left side of image) is about magnitude 16.3.
