Details:
Two images, taken 24 hours apart, show the movement of Ceres and Vesta in this composite of stacked images. The upper is Sept. 21st, the lower the 22nd. In the lower image, the red arrow shows the original placement, with the green arrow the new location. The white tick mark near each in both photos points to the same star nearby to help reveal further the displacement. Canon 2Ti, with f/1.8 50mm lens set to f/4, 3.2 sec @ ISO 1600, stacked of 15-18 images each. The first frame is lightened to help differentiate the two images.
